WARNING!
• 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 run-
ning. This is in violation of most state
and federal fire regulations 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.
CAUTION!
• Damage to the fuel system or emission
control system could result from using
an improper fuel filler cap. A poorly
fitting cap could let impurities into the
fuel system. Also, a poorly fitting after-
market cap can cause the “Malfunction
Indicator Light (MIL)” to illuminate, due
to fuel vapors escaping from the system.
• To avoid fuel spillage and overfilling, do
not “top off” the fuel tank after filling.
NOTE:
• When the fuel nozzle “clicks” or shuts off,
the fuel tank is full.
• Tighten the fuel filler cap about 1/4 turn
until you hear one click. This is an indica-
tion that the cap is properly tightened.
• If the fuel filler cap is not tightened prop-
erly, the MIL will come on. Be sure the cap
is tightened every time the vehicle is
refueled.
Loose Fuel Filler Cap Message
After fuel has been added, the vehicle diag-
nostic system can determine if the fuel filler
cap is possibly loose, improperly installed, or
damaged. If the system detects a malfunc-
tion, the “gASCAP” message will display in
the odometer display. Tighten the gas cap
until a "clicking" sound is heard. This is an
indication that the gas cap is properly tight-
ened. Push the odometer reset button to turn
the message off. If the problem persists, the
message will appear the next time the vehicle
is started. This might indicate a damaged
cap. If the problem is detected twice in a row,
the system will turn on the MIL. Resolving
the problem will turn the MIL off.
