■ 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 intuitive 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.

■Rear view monitor system camera
■ Smear effect
The rear view monitor system camera is
located on the tailgate as shown in the
illustration.
In the following cases, it may become dif-
ficult to see the images on the screen,
even when the system is functioning cor-
rectly.
●The vehicle is in a dark area, such
as at night.
● The temperature near the lens is
extremely high or low.
● Water droplets are on the camera
lens or humidity is high, such as
when it rains.
● Foreign matter, such as snow or
mud, adheres to the camera lens.
● The sun or headlights are shining
directly into the camera lens.
● A bright object such as a white wall
is reflected in the mirror surface
over the monitor.
● When the camera has scratches or
dirt on it.
If a bright light, such as sunlight
reflected off the vehicle body, is picked
up by the camera, a smear effect* char-
acteristic to the camera may occur.
*: Smear effect A phenomenon that
occurs when a bright light is picked
up by the camera; when transmitted
by the camera, the light source
appears to have a vertical streak
above and below it.

240 2-4. Using other driving systems
■Flicker effect
When the camera is used under fluorescent lights, sodium lights, mercury
lights etc., the lights and the illuminated areas may appear to flicker.
CAUTION
■When using the rear view monitor system
Observe the following precautions to avoid an accident that could result in
death or serious injuries
● Never depend solely on the rear view monitor system when reversing.
● Always check visually and with the mirrors to confirm your intended path is
clear.
● Always check the vehicle surroundi ng area, because the guide lines are
estimates of distance and location.
● The guide lines are assistant lines and do not change even if the steering
wheel is turned.
● Depicted distances between objects and flat surfaces differ from actual
distances.
● Do not use the system if the tailgate open.
■ Conditions which may affect the rear view monitor system
● If the back of the vehicle has been hit, the camera’s position and mounting
angle may have changed. Have the vehicle inspected by your Toyota
dealer.
● Rapid temperature changes, such as when hot water is poured on the
vehicle in cold weather, may cause the system to function abnormally.
● If the camera lens is dirty, it cannot transmit a clear image. Rinse with
water and wipe with a soft cloth. If extremely dirty, wash with a mild
cleanser and rinse.
● The displayed image may be darker and moving images may be slightly
distorted when the system is cold.
■ Caution while driving in reverse
Do not change modes while the vehicle is moving.

244 2-4. Using other driving systems
■If the 4LO indicator light blinks
●If the 4LO indicator continues to blink when shifting between 4H and 4L,
stop the vehicle completely, move the shift lever to N and operate the
switch again.
● If the shift lever is moved before the 4LO indicator turns on/off, the trans-
fer mode may not be shifted completely. The transfer mode disengages
both the front and rear driveshafts from the powertrain and allows the
vehicle to move regardless of the shift position. (At this time, the indicator
blinks and the buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic transmission is in
P. You or someone else could be seriously injured. You must complete the
shifting of the transfer mode.
To complete the shifting, stop the vehicle completely, return the shift lever
to N, and confirm that the shift was completed (The indicator turns on/off).
● If the engine coolant temperature is too low, the transfer mode may not
be able to be shifted. When the engine is warmer, operate the switch
again.
If the 4LO indicator light continues to blink even after attempting the above,
there may be a malfunction in the engine, the brake system or the four-
wheel drive system. In this case, you may not be able to shift between 4H
and 4L. Have the vehicle inspected by your Toyota dealer immediately.
■ Shifting to 4L
VSC is automatically turned off.
■ Four-wheel drive usage frequency
You should drive in four-wheel drive for at least 10 miles (16 km) each
month.
This will assure that the front drive components are lubricated.

254 2-4. Using other driving systems
■When the TRAC OFF indicator light comes on even if the VSC OFF
switch has not been pressed
TRAC system cannot be operated. Contact your Toyota dealer.
■ Automatic reactivation of TRAC, A-TRAC, VSC and Trailer Sway Con-
trol
Turning the engine switch off after turning off the TRAC, A-TRAC, VSC and
Trailer Sway Control systems will automatically re-enable them.
■ Sounds and vibrations caused by the ABS, TRAC, A-TRAC, VSC,
Trailer Sway Control and Brake Assist system
● A sound may be heard from the engine compartment when the engine is
started and just after the vehicle begins to move. This sound does not
indicate that a malfunction has occurred in any of these systems.
● Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ If the brake system overheats
TRAC or A-TRAC will cease operation, and the slip indicator will change
from flashing to being on continuously to alert the driver. Stop the vehicle in
a safe place. (There is no problem with continuing normal driving.)
■ Shifting to 4L
VSC and Trailer Sway Control are automatically turned off.
