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.
● Use your own eyes to confirm the vehicle’s surroundings, as the displayed
image may become faint or dark, and moving images will be distorted, or
not entirely visible when the outside temperature is low. When backing up,
be sure to check behind and all around the vehicle visually and with the
mirrors before proceeding.
● Depicted distances between objects and flat surfaces differ from actual
distances.
● Do not use the system if the back door is open.
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.

NOTICE
■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.
■ Camera precautions
●As the camera has a water proof construction, do not detach, disassemble
or modify it. This may cause incorrect operation.
● Do not subject the camera to a strong impact.
● If the camera lens becomes dirty, it cannot transmit a clear image. If water
droplets, snow, or mud adhere to the lens, rinse with water and wipe with a
soft cloth. If the lens is extremely dirty, wash it with a mild cleanser and
rinse. Do not rub hard.
● 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.
● Do not strongly rub the camera lens. If the camera lens is scratched, it
cannot transmit a clear image.
● 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.

When driving
Driving assist systems
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.
■Enhanced VSC (Enhanced Vehicle Stability Control)
Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road
surfaces by controlling steering performance.
■TRAC (Traction Control)
Helps to maintain drive power and prevent the front wheels (2WD mod-
els) or four wheels (4WD models) from spinning when starting the vehi-
cle or accelerating on slippery roads.
■ Hill-start assist control
P. 228
■Downhill assist control system (4WD models only)
P. 230
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.

224 2-4. Using other driving systems
When the Enhanced VSC/TRAC systems are operatingIf the vehicle is in danger of slip-
ping, rolling backwards when
starting on an incline, or the front
wheels (2WD models) or four
wheels (4WD models) spin, the
indicator flashes to indicate that
the Enhanced VSC/TRAC sys-
tems have been engaged.
To disable TRAC and/or Enhanced VSCIf the vehicle gets stuck in fresh snow or mud, TRAC and Enhanced
VSC may reduce power from the engine to the wheels. You may
need to turn the system off to enable you to rock the vehicle in order
to free it.
■ Turning off TRAC
Quickly push and release the
button to turn off TRAC.
The “TRAC OFF” indicator light
should come on.
Push the button again to turn the

The “TRAC OFF” and Enhanced
VSC off indicator light should
come on.
Push the button again to turn the
system back on.
■When the “TRAC OFF” indicator light comes on even if the Enhanced
VSC/TRAC off switch has not been pressed
TRAC, hill-start assist control and downhill assist control cannot be oper-
ated. Contact your Toyota dealer.
■ Automatic reactivation of TRAC and Enhanced VSC
Vehicles without smart key system
Turning the engine switch OFF after turning off the TRAC and Enhanced
VSC systems will automatically re-enable them.
Vehicles with smart key system
Turning the “ENGINE START STOP” switch OFF after turning off the
TRAC and Enhanced VSC systems will automatically re-enable them.
■ Automatic TRAC reactivation
If only the TRAC system is turned off, the TRAC system will turn on when
vehicle speed increases.
■ Automatic TRAC and Enha nced VSC reactivation
If the TRAC and Enhanced VSC systems are turned off, the systems will not
turn on even when vehicle speed increases.

226 2-4. Using other driving systems
■Sounds and vibrations caused by the ABS, TRAC, Enhanced VSC and
brake assist
● A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indi-
cate 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 when the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ EPS operation sound
When the steering wheel operates, a motor sound (whirring sound) may be
heard.
This does not indicate a malfunction.
■ Reduced effectiveness of EPS
The effectiveness of EPS 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 engine off. The sys-
tem should return to normal within 10 minutes.
■ If the slip indicator comes on...
It may indicate a malfunction in the Enhanced VSC and TRAC. Contact your
Toyota dealer.
CAUTION
■The ABS does not operate effectively when
●Tires with inadequate gripping ability are used (such as excessively worn
tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or slick road.

When driving
CAUTION
■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 in the following situ-
ations.
● 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 roads
■ 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.
Do not drive the vehicle in conditions where stability and power may be lost.
■ When the Enhanced 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 TRAC and Enhanced VSC are off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are systems to help ensure vehicle stability and driving force,
do not turn off TRAC and Enhanced VSC unless necessary.
■ Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total
load capacity. In addition, make sure that the tires are inflated to the appro-
priate tire pressure level.
The ABS and Enhanced VSC systems will not function correctly if different
tires are fitted on the vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.
■ Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause the system to malfunction.

228
2-4. Using other driving systems
Hill-start assist control
■Hill-start assist control operating conditions
The system operates in the following situations:
• The shift lever is in a position other than P.
• The parking brake is not applied.
• The accelerator pedal is not depressed.
■ 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.
Hill-start assist control helps to prevent the vehicle from rolling
backwards when starting on an incline or 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.

CAUTION
■Hill-start assist control
●Do not overly rely on hill-start assist control. Hill-start assist control may
not operate effectively on extremely steep inclines or roads covered in ice.
● Unlike the parking brake, hill-start assist control is not intended to hold the
vehicle stationary for an extended period of time. Do not attempt to use
hill-start assist control to hold the vehicle on an incline for an extended
period of time, as doing so may lead to an accident.
