■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when
the brakes are applied suddenly, or
if the brakes are applied while driv-
ing 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.
■VSC+ (Vehicle Stability Con-
trol+)
Provides cooperative control of the
ABS, TRC, VSC and EPS.

4-5. Using the driving support systems
■TRC (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
Helps to reduce the backward
movement of the vehicle when
starting on an uphill
■EPS (Electric Power Steering)
Employs an electric motor to
reduce the amount of effort needed
to turn the steering wheel.
■Active Torque Split AWD sys-
tem
Automatically switches from front-
wheel drive to all-wheel drive
(AWD) according to the driving con-
ditions, helping to ensure reliable
handling and stability. Examples of
conditions where the system will
switch to AWD are when cornering,
going uphill, starting off or acceler-
ating, and when the road surface is
slippery due to snow, rain, etc.
■Emergency brake signal
When the brakes are applied sud-
denly, the emergency flashers auto-
matically flash to alert the vehicle
behind.
■The secondary Collision Brake
(if equipped)
When the SRS airbag sensor
detects a collision and the system
operates, the brakes and brake
lights are automatically controlled
to reduce the vehicle speed and
help reduce the possibility of further
damage due to a secondary colli-
sion.
■When the TRC/VSC systems are operating
The slip indicator light will flash while the
TRC/VSC systems are operating.
■Disabling the TRC system
If the vehicle gets stuck in mud, dirt or
snow, the TRC system may reduce
power from the engine to the wheels.

●The parking brake is engaged
●2 seconds at maximum elapsed after the brake pedal is released
●Engine switch is turned to OFF
■Sounds and vibrations caused by the ABS, brake assist, VSC, TRC and hill-start assist control sys-
tems
●A sound may be heard from the
engine compartment when the brake pedal is depressed repeatedly, when the engine is started or 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 also 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 malfunc-
tion.
■Automatic reactivation of TRC and VSC systems
After turning the TRC and VSC systems
off, the systems will be automatically re- enabled in the following situations:
●When the engine switch is turned off
●If only the TRC system is turned off,
the TRC will turn on when vehicle speed increases.If both the TRC 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 engine off.
The EPS system should return to nor- mal within 10 minutes.

WARNING
●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 con-
trol to hold the vehicle on an incline, as doing so may lead to an acci-dent.
■When the TRC/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 TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-tions. As these are the systems to
help ensure vehicle stability and driv- ing force, do not turn the TRC/VSC systems off unless necessary.
■Expert mode precautions
●Do not use on public roads.
●Use only when the road conditions and safely of the surrounding area
can be ensured.
●Proper use of expert mode requires
a professional level of driving skill. When using expert mode, always check the road conditions and sur-
rounding area and drive more care- fully than usual.
■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 pres-
sure level. The ABS, TRC and VSC systems will not function correctly if different tires
are installed on the vehicle. Contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer for further information when replacing tires or wheels.
■Handling of tires and the suspen-sion
Using tires with any kind of problem
or modifying the suspension will affect the driving assist systems, and may cause a system to malfunction.
■Secondary Collision Brake (if equipped)
Do not rely solely upon the Secondary Collision Brake. This system is designed to help reduce the possibil-
ity of further damage due to a second- ary collision, however, that effect changes according to various condi-
tions. Overly relying on the system may result in death or serious injury.
■Active Torque Split AWD system
●The Active Torque Split AWD sys-tem is designed to ensure driving
stability on general roads and not for off-road driving such as for rally-ing. Do not subject the system to
extreme driving conditions.
●Drive carefully on slippery road sur-
faces.

4-6. Driving tips
Driving
the driving conditions:
 Do not try to forcibly open a win-
dow or move a wiper that is fro-
zen. Pour warm water over the
frozen area to melt the ice. Wipe
away the water immediately to
prevent it from freezing.
 To ensure proper operation of
the climate control system fan,
remove any snow that has accu-
mulated on the air inlet vents in
front of the windshield.
 Check for and remove any
excess ice or snow that may
have accumulated on the exte-
rior lights, vehicle’s roof, chassis,
around the tires or on the brakes.
 Remove any snow or mud from
the bottom of your shoes before
getting in the vehicle.
Accelerate the vehicle slowly, keep
a safe distance between you and
the vehicle ahead, and drive at a
reduced speed suitable to road
conditions.
 Park the vehicle and shift the
shift lever to 1 or R without set-
ting the parking brake. The park-
ing brake may freeze up,
preventing it from being
released. If the vehicle is parked
without setting the parking brake,
make sure to block the wheels.
Failure to do so may be danger-
ous because it may cause the
vehicle to move unexpectedly,
possibly leading to an accident.
Use the correct tire chain size when
mounting the tire chains.
Chain size is regulated for each tire
size.
Side chain:
3 mm (0.12 in.) in diameter
10 mm (0.39 in.) in width
30 mm (1.18 in.) in length
Cross chain:
4 mm (0.16 in.) in diameter
14 mm (0.55 in.) in width
25 mm (0.98 in.) in length

late on the windows for a long period.
Clean the windows with a soft, damp cloth as soon as possible.• Do not use wax or glass cleaners that
contain abrasives when cleaning the windows.• Do not use any metallic objects to
remove condensation build up.
●When the water-repellent perfor-
mance has become insufficient, the coating can be repaired. Consult any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
■Plated portions
If dirt cannot be removed, clean the
parts as follows:
●Use a soft cloth dampened with an
approximately 5% solution of neutral detergent and water to clean the dirt off.
●Wipe the surface with a dry, soft cloth to remove any remaining moisture.
●To remove oily deposits, use alcohol wet wipes or a similar product.
■Carbon film (if equipped)
●Do not attach a roof carrier on the car-bon-film. It may damage the film sur-
face.
●On l y u se lo w t em pe r a tu r e wat e r ; 50 ° C
(122°F) or less, for an automatic car wash and high pressure washer.
Do not use the high pressure washer to
the film edge to avoid coming off.
●Do not take heated water more than 90°C (194°F) directly. It may cause the film to come off easily.
●Only use a neutral detergent which is approved for car wash use and water.
●Do not wax or apply a coating to the film to keep film textured appearance.
●Dirt like bird droppings and oil should be cleaned off with a neutral detergent
immediately.
■Brake
●Painted brake calipers
• When using detergent, use neutral
detergent. Do not use hard brushes or abrasive cleaners, as they will dam-age the paint.
• Do not use detergent on the brake cal- ipers when they are hot.• Wash detergent off immediately after
use.
●Rust may form if the vehicle is parked
with wet brake pads or disc rotors, causing them to stick. Before parking the vehicle after it is washed, drive
slowly and apply the brakes several times to dry the parts.
