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 elec-
tricity.
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, pressurized fuel may spray out of 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 igni-
tion hazard.

the vehicle when it is in the sun.
Doing so may result in the following.
• Gas may leak from a cigarette lighter or spray can, and may lead to a
fire.
• The temperature inside the vehicle may cause the plastic lenses and
plastic material of eye glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the
interior of the vehicle, and may also cause a short circuit in the vehi-
cle's electrical components.
Always apply the parking brake, shift the shift lever to P (vehicles with an
automatic transmission only), stop the engine and lock the vehicle.
