• Tighten the gas cap about one quarter turn until you
hear one click. This is an indication that the cap is
properly tightened.
• If the gas cap is not tightened properly, the MIL will
come on. Be sure the gas cap is tightened every time
the vehicle is refueled.
CAUTION!
• Damage to the fuel system or emission control
system could result from using an improper fuel
cap (gas cap). A poorly fitting cap could let impu-
rities into the fuel system. Also, a poorly fitting
aftermarket cap can cause the "Malfunction Indi-
cator Light (MIL)" to illuminate, due to fuel vapors
escaping from the system.
• A poorly fitting gas cap may cause the MIL to turn
on.
• To avoid fuel spillage and overfilling, do not "top
off" the fuel tank after filling.
• Never have any smoking materials lit in or near the
vehicle when the gas cap is removed or the tank is
being filled.
• Never add fuel when the engine is running. This is
in violation of most state and federal fire regula-
tions and may cause the MIL to turn on.
• A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on
the ground while filling.
