WARNING

To avoid malfunction of the front camera

Observe the following precautions.

Otherwise, the front camera may not operate properly, possibly leading to an accident resulting in death or serious injury.

Keep the windshield clean at all times.

If the windshield is dirty or covered with an oily film, water droplets, snow, etc., clean the windshield.

If a glass coating agent is applied to the windshield, it will still be neces- sary to use the windshield wipers to remove water droplets, etc. from the area of the windshield in front of the front camera.

If the inner side of the windshield where the front camera is installed is dirty, contact your Toyota dealer.

Do not attach objects, such as stickers, transparent stickers, etc., to the outer side of the windshield in front of the front camera (shaded area in the illus- tration).

A: From the top of the windshield to approximately 0.4 in. (1 cm) below the bottom of the front camera

B: Approximately 7.9 in. (20 cm) (Approximately 4.0 in. [10 cm] to the right and left from the center of the front camera)

If the part of the windshield in front of the front camera is fogged up or cov- ered with condensation or ice, use the windshield defogger to remove the fog, condensation or ice. ( P. 393, 399, 407)

If water droplets cannot be properly removed from the area of the wind- shield in front of the front camera by the windshield wipers, replace the wiper insert or wiper blade.

Do not attach window tint to the windshield.

Replace the windshield if it is damaged or cracked.

After replacing the windshield, the front camera must be recalibrated. Con- tact your Toyota dealer for details.

Do not allow liquids to contact the front camera.

Do not allow bright lights to shine into the front camera.

Do not dirty or damage the front camera.

When cleaning the inside of the windshield, do not allow glass cleaner to contact the lens of the front camera. Also, do not touch the lens.

If the lens is dirty or damaged, contact your Toyota dealer.

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	Action
When the area around a camera is covered with dirt, moisture (fogged up, covered with condensation, ice, etc.), or other foreign matter	Using the wiper and A/C function, remove the dirt and other attached matter. ( P. 393, 399, 407)
When the temperature around the front camera is outside of the opera- tional range, such as when the vehi- cle is in the sun or in an extremely cold environment	If the front camera is hot, such as after the vehicle had been parked in the sun, use the air conditioning sys- tem 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 condi- tioning system to increase the tem- perature 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 See Owner's Manual” is displayed	Check whether there is attached materials on the radar sensor and radar sensor cover, and if there is, remove it.

257

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 cannot be properly recognized. In that case, “Pre-Collision System Unavailable See Owner's Manual” is dis- played.

Pre-collision warning

When the system determines that the possibility of a frontal collision is high, a buzzer will sound and a warning message will be displayed on the multi- information display to urge the driver to take evasive action.

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

4-5. Using the driving support systems

259

Emergency steering assist

If the system determines that the possibility of a frontal collision is high and that there is sufficient space for the vehicle to be steered into within its lane, and the driver has begun evasive maneuver or steering, emergency steering assist will assist the steering move- ments to help enhance the vehicle stability and for lane departure prevention.

During operation, the indicator will illuminate in green.

Intersection right/left turn assistance

If the system determines that there is a high possibility of a collision in the following situations, it will assist with Pre-collision warning and, if necessary Pre-collision braking.

Depending on the configuration of the intersection, it may not be possible to support.

When you turn right/left at an intersection and cross the path of an oncoming vehicle

WARNING

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.

Emergency steering assist

As emergency steering assist operation will be canceled when the system determines that lane departure prevention function has been completed.

Emergency steering assist may not operate or may be cancel in the follow- ing cases as the system may determine the driver is taking actions.

If the accelerator pedal is being depressed strongly, the steering wheel is being operated sharply, the brake pedal is being depressed or the turn signal lever is being operated. In this case, the system may deter- mine that the driver is taking evasive action and the emergency steering assist may not operate.

In some situations, while the emergency steering assist is operating, operation of the function may be canceled if the accelerator pedal is depressed strongly, the steering wheel is operated sharply or the brake pedal is being depressed and the system determines that the driver is taking evasive action.

When the emergency steering assist is operating, if the steering wheel is held firmly or is operated in the opposite direction to that which the system is generating torque, the function may be canceled.

When driving on downhill slopes, the vehicle-to-vehicle distance may become shorter.

The vehicle travels at the speed set by the driver.

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 the vehicle ahead of you stops, your vehicle will also stop (vehicle is stopped by system control). After the vehicle ahead starts off, pressing the “+ RES” switch or depressing the accelerator pedal (start-off operation) will resume follow-up cruising. If the start-off operation is not performed, sys- tem control continues to keep your vehicle stopped.

299

When the turn signal lever is operated and your vehicle moves to an over- taking lane while driving at 50 mph (80 km/h) or more, the vehicle will accelerate to help to overtake a passing vehicle.

The system’s identification of what is an overtaking lane may be deter- mined solely based on the location of the steering wheel in the vehicle (left side driver position versus right side driver position.) If the vehicle is driven to a region where the overtaking lane is on a different side from where the vehicle is normally driven, the vehicle may accelerate when the turn signal lever is operated in the opposite direction to the overtaking lane (e.g., if the driver normally operates the vehicle in a region where the overtaking lane is to the right but then drives to a region where the overtaking lane is to the left, the vehicle may accelerate when the right turn signal is activated).

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.

Dynamic radar cruise control indi- cator will come on and a message will be displayed on the multi-infor- mation display.

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

If the cruise control main switch is pressed and held for 1.5 seconds or more, the system turns on in constant speed control mode. ( P. 305)

The sensor’s detection areas are limited to the areas around the vehicle’s bumper.

Depending on the shape of the object and other factors, the detection dis- tance may shorten, or detection may be impossible.

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

There will be a short delay between object detection and display. Even at slow speeds, there is a possibility that the object will come within the sen- sor’s detection areas before the display is shown and the buzzer sounds.

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

If “Parking Assist Unavailable Clean Parking Assist Sensor” is displayed on the multi-information display

A sensor may be dirty or covered with snow or ice. In such cases, if it is removed from the sensor, the system should return to normal.
