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, tou ch an
unpainted metal surface to discharge any static electricity. It is important to
discharge static electricity before refueling because sparks re sulting from
static electricity can cause fuel vapors to ignite while refuel ing.
● Always hold the grips on the fuel tank cap and turn it slowly t o remove it.
A whooshing sound may be heard when the fuel tank cap is loosen ed.
Wait until the sound cannot be heard before fully removing the cap.
In hot weather, pressurized 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 p ossible ignition
hazard.
