WARNING
●Assisting the driver to operate the vehicle
The dynamic radar cruise control has limited capability to prev ent 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 th e 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 ca use 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 s harp up
and down gradients
Vehicle speed may exceed the set speed when driving down a stee p 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 rad ar sensor or
camera sensor
● In traffic conditions that require frequent repeated acceleration and decel-
eration
● When your vehicle is towing a trailer or during emergency towin g
● When an approach warning buzzer is heard often

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-ve hicle dis-
tance switch.
Example of deceleration crui sing 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 s peed 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 su ffi-
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 syst em then
returns to constant speed cruising.

cancels the speed control.
Vehicle-to-vehicle distance control
mode: The speed control is also
canceled when the brake pedal is
depressed.
Constant speed control mode: The
speed setting is also canceled
when the brakes are applied or the
clutch pedal (manual transmission
only) is depressed.
Pushing the lever up resumes the cruise control and returns veh icle
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, war nings may not occur even when th e
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

■Automatic cancelation of c onstant speed control mode
Constant speed control mode is automatically canceled in the following situa-
tions:
● Actual vehicle speed is more than approximately 10 mph (16 km/h ) below
the set vehicle speed.
● Actual vehicle speed falls 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.
● Pre-collision braking is activated.
● 4WD models: The operation cannot be switched for 5 seconds or m ore after
operating the front-wheel drive control switch.
If constant speed control mode is automatically canceled for an y other rea-
son, 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 b e heard.
This does not indicate a malfunction.
■ Warning messages and buzzers for d ynamic 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 detect ing the vehicle ahead
In the case of the following and depending on the conditions, o perate 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 o f vehicles, the
approach warning ( P. 273) may not be activated.
● Vehicles that cut in suddenly
● Vehicles traveling at low speeds
● Vehicles that are not moving in the same lane

WARNING
■Sensor detection information
Pay particular attention to the following instances in where th is may occur.
Failing to do so way result in the vehicle being unable to be d riven or parked
safety and possibly cause an accident.
● The sensor’s detection areas are limited to the areas around the vehicle’s
rear bumper.
● 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 prob lem.)
• 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 gr ass.
• 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 a nd 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 senso r to be
closer than they are.
2884-5. Using the driving support systems
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 w ill 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 detecte d 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
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 a rea.
Doing so may result in the sensor malfunctioning.
