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.
Doing so may cause a fire or other incident which may result in death or serious
injury.
■When opening the fuel cap
Do not remove the cap quickly. In hot weather, fuel under pressure could cause
injury by spraying out of the filler neck if the cap is suddenly removed.
