ES350_U
CAUTION
■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, pressur-
ized 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 cap
Do not use anything but a genuine Lexus fuel tank cap designed for your vehicle.
Failure to do so may cause a fire or other incident which may result in death or seri-
ous injury.
NOTICE
■Refueling
Do not spill fuel during refueling.
Failing to do so may damage the vehicle, such as causing the exhaust systems to
operate abnormally or damaging fuel system components or the vehicle's painted
surface.

CAUTION
■While driving
●Do not adjust the position of the driver’s seat while driving.
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 accident. The adjustment
mechanism may also be damaged.
■Adjusting the seat position:
●Take care when adjusting the seat position to ensure that other passengers 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.
