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.
■Turning off both TRC and VSC sys-
tems

■Automatic system cancelation of
emergency brake signal
The emergency brake signal will be can- celed in any of the following situations:
●The emergency flashers are turned 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)
●A certain amount of time elapses during operation
●The accelerator pedal is depressed a large amount
■If a message about AWD is shown on the multi-information displa y
Perform the following actions.

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.
●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.
WARNING
■When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may cause the electrical components, etc.
to catch fire.
■When cleaning the windshield
Set the wiper switch to off. If the wiper switch is in “AUTO”, the wipers may operate unexpectedly in the following
situations, and may result in hands being caught or other serious injuries and cause damage to the wiper
blades.
Off
AUTO
●When the upper part of the wind- shield where the raindrop sensor is
located is touched by hand
●When a wet rag or similar is held
close to the raindrop sensor

6-1. Maintenance and care
WARNING
●If something bumps against the windshield
●If you directly touch the raindrop sensor body or if something bumps
into the raindrop sensor
■Precautions regarding the
exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has cooled sufficiently, as touching a hot
exhaust pipe can cause burns.
■Precaution regarding the rear
bumper with Blind Spot Monitor (if equipped)
If the paint of the rear bumper is
chipped or scratched, the system may malfunction. If this occurs, consult with any authorized Toyota retailer or
Toyota authorized repairer, or any reli- able repairer.
NOTICE
■To prevent paint deterioration and corrosion on the body and components (aluminum wheels,
etc.)
●Wash the vehicle immediately in the following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar or tree sap is present on
the paint surface
• If dead insects, insect droppings or
bird droppings are present on the paint surface
• After driving in an area contami- nated with soot, oily smoke, mine dust, iron powder or chemical sub-
stances
• If the vehicle becomes heavily soiled with dust or mud
• If liquids such as benzene and gas- oline are spilled on the paint sur-face
●If the paint is chipped or scratched, have it repaired immediately.
●To prevent the wheels from corrod-ing, remove any dirt and store in a
place with low humidity when stor- ing the wheels.
■Cleaning the exterior lights
●Wash carefully. Do not use organic substances or scrub with a hard
brush. This may damage the surfaces of the lights.
●Do not apply wax to the surfaces of the lights.
Wax may cause damage to the lenses.
■To prevent damage to the wind-shield wiper arms
When lifting the wiper arms away
from the windshield, pull the driver side wiper arm upward first, and repeat for the passenger side. When
returning the wipers to their original position, do so from the passenger side first.
■When using an automatic car wash
Set the wiper switch to the off posi- tion. If the wiper switch is in “AUTO”, the wipers may operate and the wiper
blades may be damaged.
