Fuel Filler Cap (Gas Cap)
The gas cap is behind the fuel filler door. If the gas cap is
lost or damaged, be sure the replacement cap is for use
with this vehicle.
CAUTION!
Damage to the fuel system or emission control
system could result from using an improper fuel
tank filler tube cap (gas cap). A poorly fitting cap
could let impurities into the fuel system.
STARTING AND OPERATING 283
WARNING!
• Remove the fuel tank filler tube cap (gas cap)
slowly to prevent fuel spray from the filler neck
which may cause injury.
• The volatility of some fuels may cause a buildup
of pressure in the fuel tank that may increase
while you drive. This pressure can result in a
spray of fuel and/or vapors when the cap is
removed from a hot vehicle. Removing the cap
slowly allows the pressure to vent and prevents
fuel spray.
• Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank filled.
• Never add fuel to the vehicle when the engine is
running.
