CAUTION
■When refueling the vehicle
Observe the following precautions while refueling the vehicle. 
Failure to do so, may result in death or serious injury.
● Touch the vehicle or some other metal surface to discharge any static
electricity. 
Sparks resulting from discharging static electricity may cause the fuel
vapors to ignite.
● Always hold the grips on the fuel tank cap and turn it slowly to remove it. 
A whooshing sound may be heard when the fuel tank cap is loosened.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out the filler neck and cause injury.
● Do not allow anyone that has not discharged static electricity from their
bodies to come close to an open fuel tank.
● Do not inhale vaporized fuel. 
Fuel contains substances that are harmful if inhaled.
● Do not smoke while refueling the vehicle. 
Doing so may cause the fuel to ignite and cause a fire.
● Do not return to the vehicle or touch any person or object that is statically
charged. 
This may cause static electricity to build up, resulting in a possible ignition
hazard.
■ When replacing the fuel tank cap
Do not use anything but a genuine Toyota fuel tank cap designed for your
vehicle. Doing so may cause a fire or other incident which may result in
death or serious injury.

reached and easily
depressed to the extent
required. (P. 78)
Adjust the seatback so that
the controls are easily oper-
able.

CAUTION
■While driving
● Do not adjust the position of the driver’s seat. 
Doing so could cause the driver to lose control of the vehicle.
● Do not place a cushion between the driver or passenger and the seatback. 
A cushion may prevent correct posture from being achieved, and reduce
the effectiveness of the seat belt and head restraint, increasing the risk of
death or serious injury to the driver or passenger.
● Do not place anything under the front seats. 
Objects placed under the front seats may become jammed in the seat
tracks and stop the seat from locking in place. This may lead to an acci-
dent. The adjustment mechanism may also be damaged.
■ Adjusting the seat position
● Do not recline the seat more than necessary when the vehicle is in motion,
to reduce the risk of sliding under the lap belt. 
If the seat is too reclined during an accident, the lap belt may slide part the
hips and apply restraint forces directly to the abdomen or your neck may
contact the shoulder belt, increasing the risk of death or serious injury.
● Take care when adjusting the seat position to ensure that other passen-
gers are not injured by the moving seat.
● Do not put your hands under the seat or near the moving parts to avoid
injury. 
Fingers or hands may become jammed in the seat mechanism.
