WARNING
■SRS airbag precautions
● 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 pillars 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 collision.
■ Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform 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

■Avoiding damage to vehicle parts
● Do not turn the steering wheel fully in either direction and hold it there for
an extended period of time.
Doing so may damage the power steering motor.
● When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.
■ If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehi-
cle.
● It may be difficult to control your vehicle.
● The vehicle will make abnormal sounds or vibrations.
● The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( →P. 381)
■ When encounterin g flooded roads
Do not drive on a road that has flooded after heavy rain, etc. Doing so may
cause the following serious damage to the vehicle:
● Fuel cell system stalling
● Short in electrical components
● Fuel cell system damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have your Toyota dealer check the following:
● Fuel cell system
● Brake function
● Changes in quantity and quality of transmission fluid, etc.
● Lubricant condition for the bearings and suspension joints (where possi-
ble), and the function of all joints, bearings, etc.
If the shift control system is damaged by flooding, it may not be possible to
shift the shift position to P, or from P to other positions. When the shift posi-
tion cannot be changed from P to any other position, the front wheels will
lock, and you will be unable to tow the vehicle with the front wheels on the
ground, as the front wheels may be locked. In this case, transport the vehi-
cle with both front wheels or all four wheels lifted.
■ If the vehicle will not shift out of the P position
There is a possibility that the 12-volt battery is discharged. Check the 12-
volt battery in this situation.

Sensor detection information
●The sensor’s detection areas are limited to the areas around the vehicle’s
bumper.
● Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect an obstacle. 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.)
In especially cold weather, if a sensor is frozen the screen may show an
abnormal display, or obstacles may not be detected.
• 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 wireless antenna.
• Towing eyelets are installed.
• 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 a sensor to be closer
than they are.
● The shape of the obstacle may prevent a sensor from detecting it. Pay par-
ticular attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of
your vehicle
