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.

A whooshing sound may be heard when the fuel tank cap is loosened. Wait until
the sound cannot be heard before fully re moving the cap. In hot weather, pressur-
ized fuel may spray out of the filler neck and cause injury.

come close to an open fuel tank.

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 an y 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 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.
