For safety and security
CAUTION
■SRS airbag precautions
● Do not use seat accessories which cover the parts where the SRS side
airbags inflate as they may interfere with inflation of the airbags. Such
accessories may prevent the side airbags from activating correctly, disable
the system or cause the side airbags to inflate accidentally, resulting in
death or serious injury.
● Do not strike or apply significant levels of force to the area of the SRS air-
bag components.
Doing so can cause the SRS airbags to malfunction.
● Do not touch any of the component parts immediately after the SRS air-
bags have deployed (inflated) as they may be hot.
● If breathing becomes difficult after the SRS airbags have deployed, open a
door or window to allow fresh air in, or leave the vehicle if it is safe to do
so. Wash off any residue as soon as possible to prevent skin irritation.
● If the areas where the SRS airbags are stored, such as the steering wheel
pad and front and rear pillar garnishes, are damaged or cracked, have
them replaced by your Toyota dealer.
● Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents the sensor
from detecting the passenger’s weight properly. As a result, the SRS front
airbags for the front passenger may not deploy in the event of a collisi\
on.
■ Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or per form any of the following modifications
without consulting your Toyota dealer. The SRS airbags may malfunction or
deploy (inflate) accidentally, causing death or serious injury.
● Installation, removal, disassembly and repair of the SRS airbags
● Repairs, modifications, removal or replacement of the steering wheel,
instrument panel, dashboard, seats or seat upholstery, front, side and rear
pillars or roof side rails
● Repairs or modifications of the front fender, front bumper, or side of the
occupant compartment
● Installation of a grille guard (bull bars, kangaroo bar, etc.), snow plows,
winches or roof luggage carrier
● Modifications to the vehicle’s suspension system
● Installation of electronic devices such as mobile two-way radios and CD
players
● Modifications to your vehicle for a person with a physical disability

2104-5. Using the driving support systems
■The intuitive parking assist can be operated when
●Front corner sensors:
• The engine switch is in the “ON” position.
• The shift lever is in R.
• The shift lever is not in P or R and vehicle speed is less than about 6 mph
(10 km/h).
● Rear corner and rear center sensors:
• The engine switch is in the “ON” position.
• The shift lever is in R.
■ Sensor detection information
●The sensor’s detection areas are limited to the areas around the vehicle’s
front corner and rear bumpers.
● 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. (Wiping the sensors will resolve
this problem.)
• The sensor is frozen. (Thawing the area will resolve this problem.)
• 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 ultra-
sonic 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 radio 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.
• The area directly under the bumpers is not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Toyota suspension (lowered suspension, etc.) is installed.
• People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there are instances in which, because of
their shape, signs and other objects may be judged by the sensor to be closer
than they are.

Driving
CAUTION
■When the VSC and Trailer Sway Control are 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 TRAC/VSC/A-TRAC/Trailer Sway Control 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 driving
force, do not turn the TRAC/VSC/A-TRAC/Trailer Sway Control systems off
unless necessary.
■ 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 pressure level.
The ABS, TRAC, A-TRAC, VSC and Trailer Sway Control systems will not
function correctly if different tires are installed on the vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.
■ Trailer Sway Control precaution
The Trailer Sway Control system is not able to reduce trailer sway in all situ-
ations. Depending on many factors such as the conditions of the vehicle,
trailer, road surface, and driving environment, the Trailer Sway Control sys-
tem may not be effective. Refer to your trailer owner’s manual for informa-
tion on how to tow your trailer properly.
■ If trailer sway occurs
Observe the following precautions.
Failure to do so may cause death or serious injury.
● Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering wheel.
● Begin releasing the accelerator pedal immediately but very gradually to
reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle
and trailer should stabilize. ( →P. 178)

2504-6. Driving tips
When driving your vehicle off-road, please observe the following pre-
cautions to ensure your driving enjoyment and to help prevent the clo-
sure of areas to off-road vehicles.
● Drive your vehicle only in areas where off-road vehicles are permit-
ted to travel.
● Respect private property. Get owner’s permission before entering
private property.
● Do not enter areas that are clos ed. Honor gates, barriers and signs
that restrict travel.
● Stay on established roads. When c onditions are wet, driving tech-
niques should be changed or trav el delayed to prevent damage to
roads.
CAUTION
■ Off-road vehicle precautions
Always observe the following precautions to minimize the risk of death, seri-
ous injury or damage to your vehicle:
● In a rollover crash, an unbelted person is significantly more likely to die
than a person wearing a seat belt. Therefore, the driver and all passengers
should always fasten their seat belts.
● Avoid sharp turns or abrupt maneuvers, if at all possible.
Failure to operate this vehicle correctly may result in loss of control or
vehicle rollover causing death or serious injury.
● Avoid loading any items on the roof that will raise the vehicle’s center of
gravity.
● Always slow down in gusty crosswinds. Because of its profile and higher
center of gravity, your vehicle is more sensitive to side winds than an ordi-
nary passenger car. Slowing down will allow you to have better control.
● When driving off-road or in rugged te rrain, do not drive at excessive
speeds, jump, make sharp turns, strike objects, etc. This may cause loss
of control or vehicle rollover causing death or serious injury. You are also
risking expensive damage to your vehicle’s suspension and chassis.
● Do not drive horizontally across steep slopes. Driving straight up or
straight down is preferred. Your vehicle (or any similar off-road vehicle)
can tip over sideways much more easily than forward or backward.

CAUTION
■Off-road driving precautions
Always observe the following precautions to minimize the risk of death, seri-
ous injury or damage to your vehicle:
● Drive carefully when off the road. Do not take unnecessary risks by driving
in dangerous places.
● Do not grip the steering wheel spokes when driving off-road. A bad bump
could jerk the wheel and injure your hands. Keep both hands and espe-
cially your thumbs on the outside of the rim.
● Always check your brakes for effectiveness immediately after driving in
sand, mud, water or snow.
● After driving through tall grass, mud, rock, sand, rivers, etc., check that
there is no grass, bush, paper, rags, stone, sand, etc., adhering or trapped
on the underbody. Clear off any such matter from the underbody. If the
vehicle is used with these materials trapped or adhering to the underbody,
a breakdown or fire could occur.
● In a rollover crash, an unbelted person is significantly more likely to die
than a person wearing a seat belt. Therefore, the driver and all passengers
should fasten their seat belts whenever the vehicle is moving.
● When driving off-road or in rugged te rrain, do not drive at excessive
speeds, jump, make sharp turns, strike objects, etc. This may cause loss
of control or vehicle rollover causing death or serious injury. You are also
risking expensive damage to your vehicle’s suspension and chassis.

Maintenance and care
CAUTION
■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.
■ Precautions regarding the exhaust pipe
Exhaust gases 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 hot exhaust pipe can cause burns.
NOTICE
■To prevent paint deterioration and corrosion on the body and compo-
nents (aluminum wheels, etc.)
