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 re moving 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.

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.
If the fuel filler door opener switch is inopera-
ble, contact your Lexus dealer to service the
vehicle. If you must refuel your vehicle, you
can open the fuel filler door manually as
shown. The system to lower internal pressure
