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.
Pressing to turn the system off may
make it easier for you to rock the vehicle
in order to free it.
To turn the TRC system off, quickly
press and release .
The “TRC OFF” indicator light will come
on.
Press again to turn the system
back on.

on.
●The system judges from the vehicle
deceleration that is not a sudden brak-
ing operation.
■Secondary Collision Brake operat-
ing conditions (if equipped)
The system operates when the SRS air-
bag sensor detects a collision while the
vehicle is in motion.
However, the system does not operate in any of the following situations.
●The vehicle speed is below 10 km/h (6
mph)
●Components are damaged
■Secondary Collision Brake auto-
matic cancelation (if equipped)
The system is automatically canceled in
any of the following situations.
●The vehicle speed drops below
approximately 10 km/h (6 mph)

Maintenance and care
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.
●Only use low temperature water; 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.
