Observe the following precautions while refu
eling the vehicle. Failure to do so may
result in death or serious injury.
●After exiting the vehicle and before openin g 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 fr om static electricity can cause fuel vapors
to ignite while refueling.

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, pressurized fuel

●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 th at 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.
●Stop filling the tank after the fuel nozzle automatically clicks off.
