Dynamic radar cruise control
In vehicle-to-vehicle distance control mode, the vehicle automatically accelerates and decelerates to match the speed changes of the pre- ceding vehicle even if the accelerator pedal is not depressed. In con- stant speed control mode, the vehicle runs at a fixed speed. Use the dynamic radar cruise control on freeways and highways. ● Vehicle-to-vehicle distance control mode (P. 279) ● Constant speed control mode (P. 285)

Summary of functions
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. 287 • Conditions under which the vehicle-to-vehicle distance control mode
may not function correctly: →P. 289 ●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
This mode employs a radar sensor to detect the presence of vehicles up to approximately 328 ft. (100 m) ahead, determines the current vehicle-to-vehicle following distance, and operates to maintain a suit- able following distance from the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on long downhill slopes.
Driving in vehicle-to-vehicle distance control mode
Example of constant speed cruising When there are no vehicles ahead 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. Example of deceleration cruising and follow-up cruising 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. Example of acceleration 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.

Pulling the lever toward you cancels the speed control. The speed control is also canceled when the brake pedal is depressed. Pushing the lever up resumes the cruise control and returns vehicle speed to the set speed. However, cruise control does not resume when the vehicle speed is approximately 25 mph (40 km/h) or less.
When your vehicle is too close to 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. Switching to constant speed con- trol mode is only possible when operating the lever with the cruise control off. Accelerate or decelerate, with accelerator pedal operation, to the desired vehicle speed (at or above approximately 30 mph [50 km/h]) and push the lever down to set the speed. Cruise control “SET” indicator will come on. The vehicle speed at the moment the lever is released becomes the set speed.

Selecting constant speed control mode
■Dynamic radar cruise control can be set when
●The shift lever is in D or range 4 or higher of S has been selected. ●Vehicle speed is at or above approximately 30 mph (50 km/h).
■Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After acceler- ating, the set speed resumes. However, during vehicle-to-vehicle distance control mode, the vehicle speed may decrease below the set speed in order to maintain the distance to the preceding vehicle.
■Automatic cancelation of vehicle-to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the fol- lowing situations: ●Actual vehicle speed falls at or below approximately 25 mph (40 km/h). ●VSC is activated. ●TRAC is activated for a period of time. ●When the VSC or TRAC system is turned off. ●The sensor cannot detect correctly because it is covered in some way. ●Pre-collision braking is activated. ●The operation cannot be switched for 5 seconds or more after operating the
four-wheel drive control or the center differential lock switch. (4WD models) If vehicle-to-vehicle distance control mode is automatically canceled for any other reason, there may be a malfunction in the system. Contact your Toyota dealer.

■Brake system operation sound
If the brakes are applied automatically while the vehicle is in vehicle-to-vehi- cle distance control mode, a brake system operation sound may be heard. This does not indicate a malfunction.
■Warning messages and buzzers for dynamic radar cruise control
Warning messages and buzzers are used to indicate a system malfunction or to inform the driver of the need for caution while driving. If a warning message is shown on the multi-information display, read the message and follow the instructions.
■When the sensor may not be correctly detecting the vehicle ahead
In the case of the following and depending on the conditions, operate the brake pedal when deceleration of the system is insufficient or operate the accelerator pedal when acceleration is required. As the sensor may not be able to correctly detect these types of vehicles, the approach warning (P. 284) may not be activated. ●Vehicles that cut in suddenly ●Vehicles traveling at low speeds ●Vehicles that are not moving in the same lane
●Vehicles with small rear ends (trailers with no load on board, etc.)
●Motorcycles traveling in the same lane ●When water or snow thrown up by the surrounding vehicles hinders the
detecting of the sensor ●When your vehicle is pointing upwards
(caused by a heavy load in the luggage compartment, etc.)
●Preceding vehicle has an extremely high ground clearance
■Conditions under which the vehicle-to-vehicle distance control mode may not function correctly
In the case of the following conditions, operate the brake pedal (or accelera- tor pedal, depending on the situation) as necessary. As the sensor may not be able to correctly detect vehicles ahead, the system may not operate properly.
●When the vehicle ahead of you decelerates suddenly ●When driving on a road surrounded by a structure, such as in a tunnel or on
a bridge ●While the vehicle speed is decreasing to the set speed after the vehicle
accelerates by depressing the accelerator pedal
●When the road curves or when the lanes are narrow
●When steering wheel operation or your position in the lane is unstable

The diagram shows the detection range of the sensors. Note that the sensors cannot detect obstacles that are extremely close to the vehicle. The range of the sensors may change depending on the shape of the object, etc.
■The system can be operated when
●The engine switch is in ON mode. ● Intuitive parking assist function is on. ●The vehicle speed is less than about 6 mph (10 km/h). ●A shift position other than P is selected.
■Sensor detection information
●The sensor’s detection areas are limited to the areas around the vehicle’
front and rear bumpers. ●The following situations may occur during use.
• Depending on the shape of the object and other factors, the detection dis- tance may shorten, or detection may be impossible.
• Detection may be impossible if static objects draw too close to the sen- sor.
• There will be a short delay between static object detection and display (warning buzzer sounds). Even at low speeds, there is a possibility that the object will come within 11.9 in. (30 cm) before the display is shown and the warning buzzer sounds.
• It might be difficult to hear the buzzer due to the volume of the audio sys- tem or air flow noise of the air conditioning system.
• It may be difficult to hear the sound of this system due to the buzzers of other systems.

WARNING
■Cautions regarding the use of the system
There is a limit to the degree of recognition accuracy and control perfor- mance that this system can provide, do not overly rely on this system. The driver is always responsible for paying attention to the vehicle’ surroundings and driving safely.
■To ensure the system can operate properly
Observe the following precautions. Failing to do so may result in the vehicle being unable to be driven safely and possibly cause an accident. ●Do not damage the sensors, and always keep them clean. ●Do not attach a sticker or install an electronic component, such as a backlit
license plate (especially fluorescent type), fog lights, fender pole or wire- less antenna near a radar sensor.
●Do not subject the surrounding area of the sensor to a strong impact. If subjected to an impact, have the vehicle inspected by your Toyota dealer. If the front or rear bumper needs to be removed/installed or replaced, con- tact your Toyota dealer.
●Do not modify, disassemble or paint the sensors. ●Do not attach a license plate cover. ●Keep your tires properly inflated.
■When to disable the function
In the following situations, disable the function as it may operate even though there is no possibility of a collision. ●Failing to observe the warnings above. ●A non-genuine Toyota suspension (lowered suspension, etc.) is installed.
■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. ●When using a high pressure washer to wash the vehicle, do not spray the
sensors directly, as doing so may cause a sensor to malfunction. ●When using steam to clean the vehicle, do not direct steam too close to the sensors as doing so may cause a sensor to malfunction.
