■Rear view monitor system camera
■ Smear effect
In the following cases, it may become
difficult to see the images on the
screen, even when the system is func-
tioning correctly:
●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 camera has scratches or dirt on
it.
● The sun or headlights are shining
directly into the camera lens.
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.

CAUTION
■When using the rear view monito r system, observe the following pre-
cautions to avoid an accident that coul d result in death or serious inju-
ries:
● Never depend solely on the monitor system when reversing.
● Always check visually and with the mirrors to confirm your intended path is
clear.
● Depicted distances between objects and flat surfaces differ from actual
distances.
● Do not use the system if the back door is 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.
● As the camera has a water proof construction, do not detach, disassemble
or modify it. This may cause incorrect operation.
● Do not allow organic solvent, car wax, window cleaner or glass coat to
adhere to the camera. If this happens, wipe it off as soon as possible.
● If the temperature changes rapidly, such as when hot water is poured on
the vehicle in cold weather, the system may not operate normally.
● When the camera is used under fluorescent lights, sodium lights, or mer-
cury lights, the lights and the illuminated areas may appear to flicker.
● When washing the vehicle, do not apply intensive bursts of water to the
camera or camera area. Doing so may result in the camera malfunction-
ing.

Driving assist systems
When the TRAC/VSC/ABS systems are operatingThe slip indicator light will flash
while the TRAC/VSC/ABS sys-
tems are operating.
To help enhance driving safety and performance, the following sys-
tems operate automatically in res ponse to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavi ly when operating the vehicle.
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface
■Brake assist
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation
■VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces
■TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spin-
ning when starting the vehicle or accelerating on slippery roads
■Hill-start assist control
P. 256
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel

252 2-4. Using other driving systems
Disabling the TRAC systemIf the vehicle gets stuck in mud, dirt or snow, the TRAC system may
reduce power from the EV system to the wheels. Pressing to turn
the system off may make it easier for you to rock the vehicle in order
to free it. To turn the TRAC system off,
quickly press and release .
The “TRAC OFF” indicator light
will come on.
Press again to turn the sys-
tem back on.
■Turning off both TR AC and VSC systems
To turn the TRAC and VSC systems off, press and hold for more than 3
seconds while the vehicle is stopped.
The “TRAC OFF” indicator light and VS C OFF indicator light will come on.
Press again to turn the systems back on.
■ When the “TRAC OFF” indicator light comes on even if the VSC OFF
switch has not been pressed
TRAC cannot be operated. Contact your Toyota dealer.

When driving
■Sounds and vibrations caused by the ABS, brake assist, TRAC, and
VSC systems
●A sound may be heard from the motor compartment when the EV system
is started or just after the vehicle begins to move, if the brake pedal is
depressed forcefully or repeatedly, or 1 - 2 minutes after the EV system is
stopped. 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.
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may
be heard. This does not indicate a malfunction.
■ Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
●When the “POWER” switch is turned off
● If only the TRAC system is turned off, the TRAC will turn on when vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-enabling
will not occur when vehicle speed increases.
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur,
refrain from excessive steering input or stop the vehicle and turn the EV sys-
tem off. The EPS system should return to normal within 10 minutes.
■ If the slip indicator comes on...
It may indicate a malfunction in the TRAC, VSC and ABS. Contact your
Toyota dealer.

254 2-4. Using other driving systems
CAUTION
■The ABS does not operate effectively when
●The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or slick roads.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle's stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the fol-
lowing situations:
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with potholes or uneven surfaces
■ TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC system is operating.
Drive the vehicle carefully in conditions where stability and power may be
lost.
■ When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
■ When the TRAC/VSC syst ems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to ensure vehicle stability and driving force,
do not turn the TRAC/VSC systems off unless necessary.

CAUTION
■Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRAC and VSC systems will not function correctly if different tires
are installed on the vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

Hill-start assist control
■Hill-start assist control operating conditions
●The system operates in the following situations:
• The shift position is in a position other than P.
• The parking brake is not applied.
• The accelerator pedal is not depressed.
● Hill-start assist control cannot be operated while the slip indicator light is
illuminated.
■ Hill-start assist control
●While hill-start assist control is operating, the brakes remain automati-
cally applied after the driver releases the brake pedal. The stop lights and
the high mounted stoplight turn on.
● Hill-start assist control operates for about 2 seconds after the brake pedal
is released.
● If the slip indicator does not flash and the buzzer does not sound when
the brake pedal is further depressed, slightly reduce the pressure on the
brake pedal (do not allow the vehicl e to roll backward) and then firmly
depress it again. If the system still does not operate, check that the oper-
ating conditions explained above have been met.
Assists with starting off and tem porarily maintains braking power
even if the foot is re moved from the brake peda l when starting off on
an incline or a slippery slope.
To engage hill-start assist con-
trol, further depress the brake
pedal when the vehicle is
stopped completely.
A buzzer will sound once to
indicate the system is acti-
vated. The slip indicator will
also start flashing.
