CAUTION
■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.
● 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 expressways
● When weather conditions are bad enough that they may prevent the sen-
sors from functioning correctly (fog, snow, sandstorm, heavy rain, etc.)
● When an approach warning buzzer is heard often
● When your vehicle is towing a trailer or during emergency towing

CAUTION
■When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary when any of the following types of vehicles
are in front of you.
As the sensor may not be able to correctly detect these types of vehicles,
the approach warning ( P. 304) will not be activated, and a fatal or serious
accident may result.
● Vehicles that cut in suddenly
● Vehicles traveling at low speeds
● Vehicles that are not moving
● Vehicles with small rear ends (trailers with no load on board etc.)
● Motorcycles traveling in the same lane
■ Conditions under which the vehicle -to-vehicle distance control may
not function correctly
Apply the brakes as necessary in the following conditions as the radar sen-
sor may not be able to correctly detect vehicles ahead, and a fatal or serious
accident may result:
● When water or snow thrown up by the surrounding vehicles hinders the
functioning of the sensor
● When your vehicle is pointing upwards (caused by a heavy load in the lug-
gage compartment, etc.)
● When the road curves or when the lanes are narrow
● When steering wheel operation or your position in the lane is unstable
● When the vehicle ahead of you decelerates suddenly

CAUTION
■Handling the radar sensor
Observe the following to ensure the cruise control system can function effec-
tively:
Otherwise, the system may not function correctly and could result in an acci-
dent.
● Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or
damage them.
● Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may malfunction.
If the sensor or surrounding area is subject to a strong impact, always
have the area inspected and adjusted by a Toyota dealer.
● Do not disassemble the sensor.
● Do not attach accessories or stickers to the sensor, grille cover or sur-
rounding area.
● Do not modify or paint the sensor and grille cover.
● Do not replace them with non-genuine parts.

Intuitive parking assist
: If equipped
The distance from your vehicle to nearby obstacles when parallel
parking or maneuvering into a garage is measured by the sensors
and communicated via the multi- information display, the touch
screen and a buzzer. Always check the surrounding area when using
this system.
■ Types of sensors
Front corner sensors (if
equipped)
Rear corner sensors
Rear center sensors
■ Intuitive parking assist switch
Turns the intuitive parking
assist on/off
When on, the indicator light
comes on and the buzzer
sounds to inform the driver
that the system is operational.

When the sensors detect an obstacle, a graphic is shown on the multi
information display or touch screen depending on the position and
distance to the obstacle.

The system operates when the ve hicle approaches within the fol-
lowing distances to an obstacle. The indicator flashes and the
buzzer sounds when the system is operating.

Detection range of the sensorsApproximately 2.0 ft. (60 cm)
Approximately 2.8 ft. (85 cm)
Approximately 5.9 ft. (180 cm)
The diagram shows the detection
range of the sensors. Note that
the sensors cannot detect obsta-
cles that are extremely close to
the vehicle.
The range of the sensors may
change depending on the shape
of the object etc.

■Intuitive parking assist can be operated when
Vehicles without a smart key system: The engine switch is in the “ON” posi-
tion.
Vehicles with a smart key system: The “ENGINE START STOP” switch is in
IGNITION ON mode.
● Front corner sensors:
• The shift lever is not in P.
• The vehicle speed is approximately 6 mph (10 km/h) or less.
● Rear corner and back sensors:

■Sensor detection information
● 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.
• The sensor is frozen.
• 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.
• A sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or radio antenna.
• A bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or right-angled curb.
• In harsh sunlight or intense cold weather
In addition to the examples above, there are instances in which, because of
their shapes, signs and other objects may be judged by the sensor to be
closer than they are.
● 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

■ Certification (Canada only)
This ISM device complies with Canadian ICES-001.
■ When there is a malfunction
In the following cases, have the vehicle inspected by your Toyota dealer.
● If the bumper is damaged.
● If the intuitive parking assist indicator light remains on without a beep
sounds.
CAUTION
■Caution when using the Intuitive parking assist-sensor
Observe the following precautions.
Failure to do so may result in the vehicle being unable to be driven safely
and possibly cause an accident.
● Do not use the sensor at speeds in excess of 6 mph (10 km/h).
● Do not attach any accessories within the sensor range.
NOTICE
■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.
