If a warning message is displayed on the multi-information display

A system may be temporarily unavailable or there may be a malfunction in the system.

In the following situations, perform the actions specified in the table. When the normal operating conditions are detected, the message will disappear and the system will become operational.

If the message does not disappear, contact your Toyota dealer.

Situation	Actions
When the area around a camera is covered with dirt, moisture (fogged up, covered with con- densation, ice, etc.), or other for- eign matter	Using the wiper and A/C function, remove the dirt and other attached matter (P. 342, 349).
When the temperature around the front camera is outside of the operational range, such as when the vehicle is in the sun or in an extremely cold environ- ment	If the front camera is hot, such as after the vehicle had been parked in the sun, use the air conditioning system to decrease the temperature around the front camera. If a sunshade was used when the vehicle was parked, depending on its type, the sunlight reflected from the surface of the sunshade may cause the temperature of the front camera to become excessively high.
	If the front camera is cold, such after the vehicle is parked in an extremely cold environment, use the air conditioning sys- tem to increase the temperature around the front camera.
The area in front of the front camera is obstructed, such as when the hood is open or a sticker is attached to the part of the windshield in front of the front camera.	Close the hood, remove the sticker, etc. to clear the obstruction.
When “Pre-Collision System Unavailable” is displayed	Check whether there is attached materi- als on the radar sensor and radar sensor cover, and if there is, remove it.

In the following situations, if the situation has changed (or the vehicle has been driven for some time) and the normal operating conditions are detected, the message will disappear and the system will become opera- tional.

If the message does not disappear, contact your Toyota dealer.

When the temperature around the radar sensor is outside of the opera- tional range, such as when the vehicle is in the sun or in an extremely cold environment

When the front camera cannot detect objects in front of the vehicle, such as when driving in the dark, snow, or fog, or when bright lights are shining into the front camera

Depending on the conditions in the vicinity of the vehicle, the radar may judge the surrounding environment can not be properly recognized. In that case, “Pre-Collision System Unavailable” is displayed.

: If equipped

Pre-collision warning

Pre-collision brake assist

When the system determines that the possibility of a frontal colli- sion is high, the system applies greater braking force in relation to how strongly the brake pedal is depressed.

Pre-collision braking

When the system determines that the possibility of a frontal colli- sion is high, the system warns the driver. If the system determines that the possibility of a frontal collision is extremely high, the brakes are automatically applied to help avoid the collision or reduce the collision speed.

WARNING

Limitations of the pre-collision system

The driver is solely responsible for safe driving. Always drive safely, taking care to observe your surroundings.

Do not use the pre-collision system instead of normal braking operations under any circumstances. This system will not prevent collisions or lessen collision damage or injury in every situation. Do not overly rely on this sys- tem. Failure to do so may lead to an accident, resulting in death or serious injury.

Although this system is designed to help avoid a collision or help reduce the impact of the collision, its effectiveness may change according to vari- ous conditions, therefore the system may not always be able to achieve the same level of performance.

Read the following conditions carefully. Do not overly rely on this system and always drive carefully.

Conditions under which the system may operate even if there is no pos- sibility of a collision: P. 267

Conditions under which the system may not operate properly: P. 269

Do not attempt to test the operation of the pre-collision system yourself. Depending on the objects used for testing (dummies, cardboard objects imitating detectable objects, etc.), the system may not operate properly, possibly leading to an accident.

Pre-collision braking

When the pre-collision braking function is operating, a large amount of braking force will be applied.

If the vehicle is stopped by the operation of the pre-collision braking func- tion, the pre-collision braking function operation will be canceled after approximately 2 seconds. Depress the brake pedal as necessary.

The pre-collision braking function may not operate if certain operations are performed by the driver. If the accelerator pedal is being depressed strongly or the steering wheel is being turned, the system may determine that the driver is taking evasive action and possibly prevent the pre-colli- sion braking function from operating.

In some situations, while the pre-collision braking function is operating, operation of the function may be canceled if the accelerator pedal is depressed strongly or the steering wheel is turned and the system deter- mines that the driver is taking evasive action.

If the brake pedal is being depressed, the system may determine that the driver is taking evasive action and possibly delay the operation timing of the pre-collision braking function.

WARNING

When to disable the pre-collision system

In the following situations, disable the system, as it may not operate prop- erly, possibly leading to an accident resulting in death or serious injury:

When the vehicle is being towed

When your vehicle is towing another vehicle

When transporting the vehicle via truck, boat, train or similar means of transportation

When the vehicle is raised on a lift with the engine running and the tires are allowed to rotate freely

When inspecting the vehicle using a drum tester such as a chassis dyna- mometer or speedometer tester, or when using an on vehicle wheel bal- ancer

When a strong impact is applied to the front bumper or front grille, due to an accident or other reasons

If the vehicle cannot be driven in a stable manner, such as when the vehi- cle has been in an accident or is malfunctioning

When the vehicle is driven in a sporty manner or off-road

When the tires are not properly inflated

When the tires are very worn

When tires of a size other than specified are installed

When tire chains are installed

When a compact spare tire or an emergency tire puncture repair kit is used

If equipment (snow plow, etc.) that may obstruct the radar sensor or front camera is temporarily installed to the vehicle

Enabling/disabling the pre-collision system

The system is automatically enabled each time the engine switch is turned to ON.

Changing the pre-collision warning timing

The pre-collision warning timing can be changed on (P. 565) of the multi-information display.

The operation timing setting is retained when the engine switch is turned off.

The warning will begin to operate earlier than with the default timing.

This is the default setting.

The warning will begin to operate later than with the default timing.

Operational conditions

The pre-collision system is enabled and the system determines that the pos- sibility of a frontal collision with a vehicle or pedestrian is high.

Each function is operational at the following speeds:

Pre-collision warning:

Vehicle speed is between approximately 7 and 110 mph (10 and 180 km/h). (For detecting a pedestrian, vehicle speed is between approximately 7 and 50 mph [10 and 80 km/h].)

The relative speed between your vehicle and the vehicle or pedestrian ahead is approximately 7 mph (10 km/h) or more.

Pre-collision brake assist:

Vehicle speed is between approximately 20 and 110 mph (30 and 180 km/h). (For detecting a pedestrian, vehicle speed is between approximately 20 and 50 mph [30 and 80 km/h].)

The relative speed between your vehicle and the vehicle or pedestrian ahead is approximately 20 mph (30 km/h) or more.

Pre-collision braking:

Vehicle speed is between approximately 7 and 110 mph (10 and 180 km/h). (For detecting a pedestrian, vehicle speed is between approximately 7 and 50 mph [10 and 80 km/h].)

The relative speed between your vehicle and the vehicle or pedestrian ahead is approximately 7 mph (10 km/h) or more.

The system may not operate in the following situations:

If a battery terminal has been disconnected and reconnected and then the vehicle has not been driven for a certain amount of time

If the shift lever is in R

If VSC is disabled (only the pre-collision warning function will be opera- tional)

If the low speed four-wheel drive indicator is illuminated (only the pre-colli- sion warning function will be operational)

Pedestrian detection function

The pre-collision system detects pedestri- ans based on the size, profile, and motion of a detected object. However, a pedes- trian may not be detected depending on the surrounding brightness and the motion, posture, and angle of the detected object, preventing the system from operating properly. (P. 271)

Cancellation of the pre-collision braking

If either of the following occur while the pre-collision braking function is oper- ating, it will be canceled:

The accelerator pedal is depressed strongly.

The steering wheel is turned sharply or abruptly.

Conditions under which the system may operate even if there is no pos- sibility of a collision

In some situations such as the following, the system may determine that there is a possibility of a frontal collision and operate.

When the warning buzzer sounds, check the surrounding road situation and carefully operate the steering wheel to move the vehicle back to the center of the lane.

: If equipped

Vehicle sway warning

WARNING

Before using LDA system

Do not rely solely upon the LDA system. The LDA system does not auto- matically drive the vehicle or reduce the amount of attention that must be paid to the area in front of the vehicle. The driver must always assume full responsibility for driving safely by always paying careful attention to the sur- rounding conditions and operating the steering wheel to correct the path of the vehicle. Also, the driver must take adequate breaks when fatigued, such as from driving for a long period of time.

Failure to perform appropriate driving operations and pay careful attention may lead to an accident, resulting in death or serious injury.

To avoid operating LDA system by mistake

When not using the LDA system, use the LDA switch to turn the system off.

WARNING

Before using dynamic radar cruise control

Driving safely is the sole responsibility of the driver. Do not rely solely on the system, and drive safely by always paying careful attention to your sur- roundings.

The dynamic radar cruise control provides driving assistance to reduce the driver’s burden. However, there are limitations to the assistance provided. Read the following conditions carefully. Do not overly rely on this system and always drive carefully.

When the sensor may not be correctly detecting the vehicle ahead:

P. 291

Conditions under which the vehicle-to-vehicle distance control mode may not function correctly: P. 293

Set the speed appropriately depending on the speed limit, traffic flow, road conditions, weather conditions, etc. The driver is responsible for checking the set speed.

Even when the system is functioning normally, the condition of the preced- ing vehicle as detected by the system may differ from the condition observed by the driver. Therefore, the driver must always remain alert, assess the danger of each situation and drive safely. Relying on this sys- tem or assuming the system ensures safety while driving can lead to an accident, resulting in death or serious injury.

Switch the dynamic radar cruise control off using the “ON-OFF” button when not in use.

Cautions regarding the driving assist systems

Observe the following precautions, as there are limitations to the assistance provided by the system.

Failure to do so may cause an accident resulting in death or serious injury.

Assisting the driver to measure following distance

The dynamic radar cruise control is only intended to help the driver in determining the following distance between the driver’s own vehicle and a designated vehicle traveling ahead. It is not a mechanism that allows care- less or inattentive driving, and it is not a system that can assist the driver in low-visibility conditions. It is still necessary for driver to pay close attention to the vehicle’s surroundings.

WARNING

Assisting the driver to judge proper following distance

The dynamic radar cruise control determines whether the following dis- tance between the driver’s own vehicle and a designated vehicle traveling ahead is within a set range. It is not capable of making any other type of judgement. Therefore, it is absolutely necessary for the driver to remain vigilant and to determine whether or not there is a possibility of danger in any given situation.

Assisting the driver to operate the vehicle

The dynamic radar cruise control has limited capability to prevent or avoid a collision with a vehicle traveling ahead. Therefore, if there is ever any danger, the driver must take immediate and direct control of the vehicle and act appropriately in order to ensure the safety of all involved.

Situations unsuitable for dynamic radar cruise control

Do not use dynamic radar cruise control in any of the following situations. Doing so may result in inappropriate speed control and could cause an acci- dent resulting in death or serious injury.

Roads where there are pedestrians, cyclists, etc.

In heavy traffic

On roads with sharp bends

On winding roads

On slippery roads, such as those covered with rain, ice or snow

On steep downhills, or where there are sudden changes between sharp up and down gradients

Vehicle speed may exceed the set speed when driving down a steep hill.

At entrances to freeways and highways

When weather conditions are bad enough that they may prevent the sen- sors from detecting correctly (fog, snow, sandstorm, heavy rain, etc.)

When there is rain, snow, etc., on the front surface of the radar sensor or front camera

In traffic conditions that require frequent repeated acceleration and decel- eration

When your vehicle is towing a trailer or during emergency towing

When an approach warning buzzer is heard often

Note that vehicle-to-vehicle distance will close in when traveling on long downhill slopes.

The vehicle travels at the speed set by the driver. The desired vehicle-to- vehicle distance can also be set by operating the vehicle-to-vehicle dis- tance switch.

When a preceding vehicle driving slower than the set speed appears

When a vehicle is detected running ahead of you, the system automatically decelerates your vehicle. When a greater reduction in vehicle speed is necessary, the system applies the brakes (the stop lights will come on at this time). The system will respond to changes in the speed of the vehicle ahead in order to maintain the vehicle-to-vehicle distance set by the driver. Approach warning warns you when the system cannot decelerate suffi- ciently to prevent your vehicle from closing in on the vehicle ahead.

When there are no longer any preceding vehicles driving slower than the set speed

The system accelerates until the set speed is reached. The system then returns to constant speed cruising.

Radar cruise control indicator will come on and a message will be displayed on the multi-information display.

Press the button again to deacti- vate the cruise control.

If the “ON-OFF” button is pressed and held for 1.5 seconds or more, the system turns on in constant speed control mode. (P. 289)

Cruise control “SET” indicator will come on.

The vehicle speed at the moment the lever is released becomes the set speed.

Increases the speed Decreases the speed

Fine adjustment: Momentarily move the lever in the desired direction.

Large adjustment: Hold the lever up or down to change the speed, and release when the desired speed is reached.

In the vehicle-to-vehicle distance control mode, the set speed will be increased or decreased as follows:

For the U.S. mainland, Hawaii

Fine adjustment: By 1 mph (1.6 km/h)*1 or 1 km/h (0.6 mph)*2 each time the lever is operated

Large adjustment: Increases or decreases in 1 mph (1.6 km/h)*1 or 1 km/h (0.6 mph)*2 increments for as long as the lever is held

Fine adjustment: By 1 mph (1.6 km/h)*1 or 1 km/h (0.6 mph)*2 each time the lever is operated

Large adjustment: Increases or decreases in 5 mph (8 km/h)*1 or 5 km/h (3.1 mph)*2 increments for as long as the lever is held

Fine adjustment: By 1 mph (1.6 km/h)*1 or 1 km/h (0.6 mph)*2 each time the lever is operated

Large adjustment: The speed will continue to change while the lever is held.

*1: When the set speed is shown in “MPH”

*2: When the set speed is shown in “km/h”

Long Medium Short

The vehicle-to-vehicle distance is set automatically to long mode when the engine switch is turned to ON.

If a vehicle is running ahead of you, the preceding vehicle mark will also be displayed.

Distance options	Vehicle-to-vehicle distance
Long	Approximately 160 ft. (50 m)
Medium	Approximately 130 ft. (40 m)
Short	Approximately 100 ft. (30 m)

1 Pulling the lever toward you cancels the speed control.

The speed control is also canceled when the brake pedal is depressed.

However, cruise control does not resume when the vehicle speed is approximately 25 mph (40 km/h) or less.

a vehicle ahead, and sufficient automatic deceleration via the cruise control is not possible, the display will flash and the buzzer will sound to alert the driver. An example of this would be if another driver cuts in front of you while you are following a vehicle. Depress the brake pedal to ensure an appropriate vehicle-to- vehicle distance.

Warnings may not occur when

In the following instances, warnings may not occur even when the vehicle-to-vehicle distance is small.

When the speed of the preceding vehicle matches or exceeds your vehicle speed

When the preceding vehicle is traveling at an extremely slow speed

Immediately after the cruise control speed was set

When depressing the accelerator pedal

When constant speed control mode is selected, your vehicle will main- tain a set speed without controlling the vehicle-to-vehicle distance. Select this mode only when vehicle-to-vehicle distance control mode does not function correctly due to a dirty radar sensor, etc.

With the cruise control off, press and hold the “ON-OFF” button for 1.5 seconds or more.

Immediately after the “ON-OFF” button is pressed, the radar cruise control indicator will come on. Afterwards, it switches to the cruise control indicator.

WARNING

Sensor detection information

Pay particular attention to the following instances in where this may occur. Failing to do so way result in the vehicle being unable to be driven or parked safety and possibly cause an accident.

The sensor’s detection areas are limited to the areas around the vehicle’s front corner and rear bumpers.

Certain vehicle conditions and the surrounding environment may affect the ability of the sensor to correctly detect obstacles. Particular instances where this may occur are listed below.

There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve this problem.)

The sensor is frozen. (Thawing the area will resolve this problem.)

The sensor is covered in any way.

The vehicle is leaning considerably to one side.

On an extremely bumpy road, on an incline, on gravel, or on grass.

The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines, air brakes of large vehicles, or other loud noises producing ultrasonic waves.

There is another vehicle equipped with parking assist sensors in the vicinity.

The sensor is coated with a sheet of spray or heavy rain.

The vehicle is equipped with a fender pole or radio antenna.

The bumper or sensor receives a strong impact.

The vehicle is approaching a tall or curved curb.

In harsh sunlight or intense cold weather.

The area directly under the bumpers is not detected.

If obstacles draw too close to the sensor.

A non-genuine Toyota suspension (lowered suspension, etc.) is installed.

A backlit license plate, license plate holder, etc., are installed.

People may not be detected if they are wearing certain types and color- ing of clothing.

People, animals, and moving objects may not be able to be detected. In addition to the examples above, there are instances in which, because of their shape, signs and other objects may be judged by the sensor to be closer than they are.

WARNING

The shape of the obstacle may prevent the sensor from detecting it. Pay particular attention to the following obstacles:

Wires, fences, ropes, etc.

Cotton, snow and other materials that absorb sound waves

Sharply-angled objects

Low obstacles

Tall obstacles with upper sections projecting outwards in the direction of your vehicle

The following situations may occur during use.

Depending on the shape of the obstacle and other factors, the detection distance may shorten, or detection may be impossible.

Obstacles may not be detected if they are too close to the sensor.

There will be a short delay between obstacle detection and display. Even at slow speeds, there is a possibility that the obstacle will come within the sensor’s detection areas before the display is shown and the warning beep sounds.

Thin posts or objects lower than the sensor may not be detected for col- lision when approached, even if they have been detected once.

It might be difficult to hear beeps due to the volume of audio system or air flow noise of air conditioning system.

NOTICE

When using intuitive parking assist-sensor

In the following situations, the system may not function correctly due to a sensor malfunction, etc. Have the vehicle checked by your Toyota dealer.

A beep does not sound when you turn the main switch on.

The intuitive parking assist operation display flashes, and a beep sounds when no obstacles are detected.

If the area around a sensor collides with something, or is subjected to strong impact.

If the bumper collides with something.

If the display shows continuously without a beep.

If a display error occurs, first check the sensor.

If the error occurs even if there is no ice, snow or mud on the sensor, it is likely that the sensor is malfunctioning.

Notes when washing the vehicle

Do not apply intensive bursts of water or steam to the sensor area. Doing so may result in the sensor malfunctioning.

The limits of tire gripping performance have been exceeded (such as excessively worn tires on a snow covered road).

The vehicle hydroplanes while driving at high speed on wet or slick roads.

Stopping distance when the ABS is operating may exceed that of nor- mal conditions

The ABS is not designed to shorten the vehicle’s stopping distance. Always maintain a safe distance from the vehicle in front of you, especially in the following situations:

When driving on dirt, gravel or snow-covered roads

When driving with tire chains

When driving over bumps in the road

When driving over roads with potholes or uneven surfaces

TRAC/VSC may not operate effectively when

Directional control and power may not be achievable while driving on slip- pery road surfaces, even if the TRAC/VSC system is operating.

Drive the vehicle carefully in conditions where stability and power may be lost.

Hill-start assist control does not operate effectively when

Do not overly rely on hill-start assist control. Hill-start assist control may not operate effectively on steep inclines and roads covered with ice.

Unlike the parking brake, hill-start assist control is not intended to hold the vehicle stationary for an extended period of time. Do not attempt to use hill-start assist control to hold the vehicle on an incline, as doing so may lead to an accident.

When the TRAC/VSC/Trailer Sway Control are activated

The slip indicator light flashes. Always drive carefully. Reckless driving may cause an accident. Exercise particular care when the indicator light flashes.

WARNING

When the TRAC/VSC/Trailer Sway Control systems are turned off

Be especially careful and drive at a speed appropriate to the road condi- tions. As these are the systems to help ensure vehicle stability and driving force, do not turn the TRAC/VSC/Trailer Sway Control systems off unless necessary.

Trailer Sway Control is part of the VSC system and will not operate if VSC is turned off or experiences a malfunction.

Replacing tires

Make sure that all tires are of the specified size, brand, tread pattern and total load capacity. In addition, make sure that the tires are inflated to the recommended tire inflation pressure level.

The ABS, TRAC, VSC and Trailer Sway Control systems will not function correctly if different tires are installed on the vehicle.

Contact your Toyota dealer for further information when replacing tires or wheels.

Handling of tires and the suspension

Using tires with any kind of problem or modifying the suspension will affect the driving assist systems, and may cause a system to malfunction.

Trailer Sway Control precaution

The Trailer Sway Control system is not able to reduce trailer sway in all situ- ations. Depending on many factors such as the conditions of the vehicle, trailer, road surface, and driving environment, the Trailer Sway Control sys- tem may not be effective. Refer to your trailer owner’s manual for informa- tion on how to tow your trailer properly.

If trailer sway occurs

Observe the following precautions.

Failure to do so may cause death or serious injury.

Firmly grip the steering wheel. Steer straight ahead.

Do not try to control trailer swaying by turning the steering wheel.

Begin releasing the accelerator pedal immediately but very gradually to reduce speed.

Do not increase speed. Do not apply vehicle brakes.

If you make no extreme correction with the steering or brakes, your vehicle and trailer should stabilize. (P. 213)

WARNING

Trailer brake type setting

It is the responsibility of the driver to make sure the trailer brakes are func- tioning normally and adjusted appropriately. Failure to check and maintain trailer brakes may result in loss of vehicle control, crash, or serious injury. Trailer brake control system will work with most electric and electric-over- hydraulic trailer braking systems up to 3 axles (24A output to trailer brakes). Please be sure to test compatibility with the system at low speeds and in a safe area. If a warning message appears in the multi-information display (P. 500), have the vehicle inspected by your Toyota dealer immediately. Some electric-over-hydraulic trailer brakes will take some minimum output to activate. Trailer brake control system will not work with trailer hydraulic surge brakes.

When driving on slippery road surfaces

When stopping with ABS activated, output to the trailer might be reduced in order to reduce the likelihood of trailer wheels to lock. The trailer is not equipped with ABS. Drive safely on slippery road surfaces.
