nSensor detection information
lCertain 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 sensor will resolve
this problem.)
The sensor is frozen. (Thawing the sensor will resolve this problem.)
The sensor is covered in any way.
In harsh sunlight or intense cold weather.
When driving on bumpy, sloped or gravel roads, or over grass.
If there is something producing ultrasonic waves nearby, such as
another vehicle’s horn, motorcycle engine noise, air braking sound
from heavy−duty vehicles, or another vehicle using the park assist sys−
tem.
In heavy rain, or if water is splashed on the sensors.
The vehicle is leaning considerably to one side.
If a commercial fender pole or radio antenna is installed.
If moving towards a high curb or a curb corner.
If towing eyelet is installed on your vehicle.
The bumper or sensor receives a strong impact.
A non−genuine Toyota suspension (lowered suspension etc.) is
installed.
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.
lThe shape of the obstacle may prevent the sensor from detecting it. Pay
particular attention to the following obstacles.
Thin objects such as wire, fencing or rope.
Objects that absorb sound waves, such as cotton or snow.
Objects with sharp corners.
Low objects.
Objects where the upper section projects out over the lower section.

CAUTION
nWhen using the Toyota park assist system
Observe the following precautions.
Failing to do so may result in the vehicle being unable to be driven safely
and possibly cause an accident.

lDo not install accessories within the sensors’ detection areas.
NOTICE
nWhen washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.

nThe fourwheel drive control switch can be operated when
lThe “ENGINE START STOP” switch is in IGNITION ON mode.
lThe shift lever is in the “N” position.
lThe vehicle is stopped completely.
nAdvice for driving on slippery roads in “L4” (low speed position)
lIf you shift the four−wheel drive control switch to “L4” and the shift lever to
the “2” range of “S” while driving in steep off−road areas, the output of the
brake can be controlled effectively by the active traction control system,
which assists the driver to control the driving power of 4 wheels.
lUse the “1” range of “S” of the shift lever for maximum power and traction
when your wheels get stuck or when driving down a steep incline. In the
following cases, the output of the brake can be controlled by the active
traction control system if the engine speed is under 3,000 rpm (normally
under 3,000 rpm when the wheels get unstuck).
The four−wheel drive control switch is in the “L4” position and the shift
lever is in the “1” range of “S” or the shift lever is in “D” or “S” with the
transmission downshifted to first gear.
The four−wheel drive control switch is in the “L4” position and the shift
lever is in the “R” position.
nThe center differential lock/unlock button can be operated when
lThe “ENGINE START STOP” switch is in IGNITION ON mode.
lThe vehicle speed is less than 60 mph (100 km/h).
nLocking/unlocking the center differential
lWhen the center differential is locked, VSC (vehicle stability control) is
automatically turned off. (The center di
fferential lock and “VSC OFF” indi−
cator lights come on.)
lIf the operation is not completed, the center differential lock indicator
blinks. If the indicator light does not turn off when unlocking the center
differential, drive straight ahead while accelerating or decelerating, or
drive in reverse.
lIf the center differential lock/unlock is not completed within 5 seconds
while the cruise control system is on, cancel the cruise control system.
