CAUTION
■If a safety system warning light does not come on
Should a safety system light such as the ABS or SRS airbag warning light
not come on when you start the engine, this could mean that these systems
are not available to help protect you in an accident, which could result in
death or serious injury. Have the vehicle inspected by your Toyota dealer
immediately if this occurs.
■ Warning lights
Warning lights inform the driver of malfunctions in any of the
vehicle’s systems. ( P. 504)
*1: These lights turn on when the engine switch is turned to the “ON”
position to indicate that a system check is being performed. They
will turn off after the engine is started, or after a few seconds. There
may be a malfunction in a system if a light does not come on, or if
the lights do not turn off. Have the vehicle inspected by your Toyota
dealer for details.

When driving
■Sensor detection information
●Certain 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.
• The sensor is frozen.
• The 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.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather
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.
● The shape of the obstacle may prevent the sensor from detecting it. Pay
particular attention to the following obstacles:
• Wires, fences, ropes etc.
• Cotton, snow and other materials that absorb radio waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction
of your vehicle
• Objects just under the bumper
• Objects very close to your vehicle
• A person near the vehicle (depending on the type of clothes worn)

Driving assist systems
When VSC and TRAC are operating
If the vehicle is in danger of slip-
ping or the front wheels (2WD
models), or 4 wheels (AWD mod-
els) spin, the indicator flashes to
indicate that VSC/TRAC system
have been engaged.
A buzzer (intermittent) sounds to
indicate that VSC is 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)
Maintains drive power and prevents the front wheels (2WD models) or
4 wheels (AWD models) from spinning when starting the vehicle or
accelerating on slippery roads.

216 2-4. Using other driving systems
To disable TRAC (2WD models only)If the vehicle gets stuck in fresh snow or mud, TRAC may reduce
power from the engine to the wheels. You may need to turn the sys-
tem off to enable you to rock the vehicle in order to free it.
■ Turning off TRAC
Push the button to turn off
TRAC.
The “TRAC OFF” indicator light
should come on.
Push the button again to turn the
system back on.
■ Automatic reactivation of TRAC (2WD models only)
Turning the engine switch off after turning off the TRAC system will automat-
ically re-enable it.
■ Sounds and vibrations caused by ABS, brake assist, VSC and TRAC
●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 after ABS is activated.
• The brake pedal may move down slightly after ABS is activated.

When driving
■Another situation in which the “T RAC OFF” indicator light comes on
(2WD models only)
When the “VSC” warning light comes on, the “TRAC OFF” indicator light
comes on even if the “TRAC OFF” switch is not pushed.
CAUTION
■ 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 the wet or slick
road.
■ Stopping distance when ABS is operating on the wet or slick roads
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.

218 2-4. Using other driving systems
CAUTION
■When VSC is activated
The slip indicator light flashes and a warning buzzer sounds. Always drive
carefully. Reckless driving may cause an accident. Exercise particular care
when the indicator light flashes and a buzzer sounds.
■ When TRAC is off (2WD models only)
Be especially careful and drive at a speed appropriate to the road condi-
tions. As this is a system to ensure vehicle stability and driving force, do not
turn off TRAC 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 recom-
mended tire pressure level.
The ABS and VSC systems will not function correctly if different tires are fit-
ted 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.

When driving
●
Due to the added load of the trailer, your vehicle's engine may
overheat on hot days (at temperatures over 85°F [30°C]) when
driving up a long or steep grade. If the engine coolant temperature
gauge indicates overheating, immedi ately turn off the air condition-
ing (if in use), pull your vehicle off the road and stop in a safe spot.
(  P. 536)
● Always place wheel blocks under both the vehicle and the trailer
wheels when parking. Apply the parking brake firmly, and put the
transmission in P. Avoid parking on a slope, but if unavoidable, do
so only after performing the following:
Apply the brakes and keep them applied.
Have someone place wheel blocks under both the vehicle and
trailer wheels.
When the wheel blocks are in pl ace, release the brakes slowly
until the blocks absorb the load.
Apply the parking brake firmly.
Shift into P and turn off the engine.
● When restarting after parking on a slope:
With the transmission in P, start the engine. Be sure to keep
the brake pedal pressed.
Shift into a forward gear. If reversing, shift into R.
Release the parking brake and brake pedal, and slowly pull or
back away from the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks.

Maintenance and care
■
Adding fluid
Make sure to check the fluid type and prepare the necessary items.
Fluid type FMVSS No.116 DOT 3 or SAE J1703 brake fluid
Items Clean funnel
■ Brake fluid can absorb moisture from the air
Excess moisture in the fluid can cause a dangerous loss of braking effi-
ciency. Use only newly opened brake fluid.
CAUTION
■When filling the reservoir
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with clean
water immediately.
If you still experience discomfort, see a doctor.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious pro\
blem.
