CAUTION
■When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do so may
result in death or serious injury.
●After exiting the vehicle and before opening the fuel door, touch an unpainted
metal surface to discharge any static electricity. It is important to discharge static
electricity before refueling because sparks resulting from static electricity can
cause fuel vapors to ignite while refueling.
●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 body 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 refueling
Securely insert the fuel nozzle into the fuel filler neck. If fuel is added with the nozzle
slightly lifted away from the fuel filler neck, the automatic shut off function may not
operate, resulting in fuel overflowing from the tank.
■When replacing the fuel cap
Do not use anything but a genuine Lexus fuel tank cap designed for your vehicle.
Doing so may cause a fire or other incident which may result in death or serious
injury.
