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, pressur-
ized fuel may spray out of 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 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.
