250 STARTING AND OPERATING
Fuel Filler Cap
CAUTION!
• Damage to the fuel system or emissions 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 and may
cause the "Malfunction Indicator Light (MIL)" to
turn on, due to fuel vapors escaping from the
system.
• To avoid fuel spillage and overfilling, do not "top
off" the fuel tank after filling.
WARNING!
• Never have any smoking materials lit in or near the
vehicle when the gas cap is removed or the tank is
being filled.
