4-5. Using the driving support systems
Driving
●Sharply-angled objects
●Low objects
●Tall objects with upper sections pro- jecting outwards in the direction of your vehicle
■Situations in which the system may
not operate properly
Certain vehicle conditions and the sur- rounding environment may affect the
ability of a sensor to correctly detect objects. Particular instances where this may occur are listed below.
●There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors
will resolve this problem.)
●A sensor is frozen. (Thawing the area
will resolve this problem.) In especially cold weather, if a sensor is frozen the sensor display may be
displayed abnormally, or objects, such as a wall, may not be detected.
●When a sensor or the area around a sensor is extremely hot or cold.
●On an extremely bumpy road, on an incline, on gravel, or on grass.
●When vehicle horns, vehicle detec-tors, motorcycle engines, air brakes of large vehicles, the clearance sonar of
other vehicles or other devices which produce ultrasonic waves are near the vehicle
●A sensor is coated with a sheet of spray or heavy rain.
●If objects draw too close to the sensor.
●Pedestrians that are hard to reflect ultrasonic waves (ex. skirts with gath-ers or frills).
●When objects that are not perpendicu-
lar to the ground, not perpendicular to
the vehicle traveling direction, uneven, or waving are in the detection range.
●Strong wind is blowing
●When driving in inclement weather such as fog, snow or a sandstorm
●When an object that cannot be detected is between the vehicle and a detected object
●If an object such as a vehicle, motor-cycle, bicycle or pedestrian cuts in
front of the vehicle or runs out from the side of the vehicle
●If the orientation of a sensor has been changed due to a collision or other impact
●When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an addi- tional trim strip, etc.), bicycle carrier, or snow plow
●If the front of the vehicle is raised or lowered due to the carried load
●If the vehicle cannot be driven in a stable manner, such as when the
vehicle has been in an accident or is malfunctioning
●When a tire chains, compact spare tire or an emergency tire puncture repair kit is used
■Situations in which the system may
operate even if there is no possibil- ity of a collision
In some situations, such as the follow-
ing, the system may operate even though there is no possibility of a colli-sion.
●When driving on a narrow road

4-5. Using the driving support systems
●When driving toward a banner, flag,
low-hanging branch or boom barrier (such as those used at railroad cross-ings, toll gates and parking lots)
●When there is a rut or hole in the sur-face of the road
●When driving on a metal cover (grat-ing), such as those used for drainage
ditches
●When driving up or down a steep
slope
●If a sensor is hit by a large amount of
water, such as when driving on a flooded road
●There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors will resolve this problem.)
●A sensor is coated with a sheet of spray or heavy rain
●When driving in inclement weather such as fog, snow or a sandstorm
●When strong winds are blowing
●When vehicle horns, vehicle detec-tors, motorcycle engines, air brakes of large vehicles, the clearance sonar of
other vehicles or other devices which produce ultrasonic waves are near the vehicle
●If the front of the vehicle is raised or lowered due to the carried load
●If the orientation of a sensor has been changed due to a collision or other
impact
●The vehicle is approaching a tall or
curved curb
●Driving close to columns (H-shaped
steel beams, etc.) in multi-story park- ing garages, construction sites, etc.
●If the vehicle cannot be driven in a
stable manner, such as when the vehicle has been in an accident or is malfunctioning
●On an extremely bumpy road, on an incline, on gravel, or on grass
●When a tire chains, compact spare tire or an emergency tire puncture repair
kit is used
■Detection range of the sensors
Approximately 100 cm (3.3 ft.)
Approximately 150 cm (4.9 ft.)
Approximately 60 cm (2.0 ft.)

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
To turn the TRC and VSC systems off,

■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

6-1. Maintenance and care
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
