GS350/250_EE (OM30C36E)
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, pressurized fuel may spray out 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 igni-
tion hazard.
When refueling
Observe the following precautions to prevent fuel overflowing from the
fuel tank:
Securely insert the fuel nozzle into the fuel filler neck.
Stop filling the tank after the fuel nozzle automatically clicks off.
Do not top off the fuel tank.
NOTICE
Refueling
Do not spill fuel during refueling.
Doing so may damage the vehicle, such as causing the emission control
system to operate abnormally or damaging fuel system components or the
vehicle’s painted surface.
