CAUTION
■Conditions under which the vehicle -to-vehicle distance control may
not function correctly
Apply the brakes as necessary in the following conditions as the laser radar
sensor 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
● When your vehicle is towing a trailer or during emergency towing
■ Handling the laser 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 clean at all times.
Clean the sensor 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, surrounding area.
● Do not modify or paint the sensor.
● Do not replace them with non-genuine parts.

Intuitive parking assist
: If equipped
The intuitive parking assist is designed to inform you of the approxi-
mate distance between your vehicle and an obstruction by indicator
and buzzer when parking the veh icle. This system uses sensors to
detect obstructions.
This system works when the engine switch is in the ON position and
the shift lever is not in P.
Back and rear corner sensors work only when the shift lever is in
R.
Front corner sensors work when:
● The shift lever is in R
● The shift lever is not in P or R and vehicle speed is approximate
6 mph (10 km/h) or less.

■Intuitive parking assist switch
Press the switch to turn on.
(To turn off, press the switch
again.)
When on, the buzzer sounds
to inform the driver that the
system is operational. At this
time, the indicator will come
on.

When driving
■When two or more obstacles are detected simultaneously
The buzzer system responds to the nearest zone.
■ When multiple obstacles are detected in front and behind the
vehicle at the same time
The buzzer will change in the following manner.
● If an obstacle has been detected within 15.7 in. (400 mm) of the
front or 33.5 in. (850 mm) in rear of the vehicle (a continuous
buzzer is sounding), and a new obstacle is detected at the other
end of the vehicle, the buzzer will sound 7 times then one contin-
uous buzzer.
● If an obstacle has been detected within 15.7 in. (400 mm) of the
front or 33.5 in. (850 mm) in rear of the vehicle (a continuous
buzzer is sounding), and a new ob stacle is detected at the same
way at the other end of the vehi cle, the buzzer will sound 3 times
then one continuous buzzer.

Sensors that operate and detection rangeThe following diagrams show the sensor detection range. Note that
sensors may not be able to detect obstacles that are extremely close
to the vehicle.

sors may not be able to detect obstacles that are extremely close to the vehi-
cle.
The range of the sensors may change depending on the shape of the object\
etc.

■Sensor detection information
●Certain vehicle conditions and the surrounding environment may affect
the ability of a sensor to correctly detect an obstacle. Particular instances
where this may occur are listed below.
• There is dirt, snow or ice on a sensor.
• A sensor is frozen.
• A 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.
• The area directly under the bumpers is not detected. Objects lower than the sensors or thin stakes etc. may be detected ini-
tially, but as they draw closer, they may cease to be detected.
• A towing hitch is mounted to the vehicle.
• A non-genuine Toyota suspension (lowered suspension etc.) is installed.
• When attaching a two-way radio antenna.
• When a towing eyelet is mounted on your vehicle.
• When the bumper is damaged.
In addition to the examples above, there are instances in which, because of
their shapes, signs and other objects may be judged by a sensor to be closer
than they are.

224 2-4. Using other driving systems
●The shape of the obstacle may prevent a 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
• A person near the vehicle (depending on the type of clothes worn)
• When the bumper is damaged.
■ Certification (Canada only)
This ISM device complies with Canadian ICES-001.
■ If the indicator is continuously on
Have the vehicle inspected by your Toyota dealer.
■ If the indicator remains blinking but do not sound the buzzer
Clean the sensors with soft cloth.
CAUTION
■Caution when using the intuitive parking assist
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.
● When moving forward or reversing, always check your surroundings for
safety and drive carefully.
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.
