Fuel Filler Cap (Gas Cap)

The gas cap is located behind the fuel filler door, on the driver’s side of the vehicle. If the gas cap is lost or damaged, be sure the replacement cap has been designed for use with this vehicle.

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 impurities into the fuel system. Also, a poorly fitting aftermarket cap can cause the “Malfunction Indicator 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.

WARNING:
• Never have any smoking materials lit in or near the vehicle when the gas cap is removed or the tank filled.
• Never add fuel when the engine is running. This is in violation of most state and federal fire regulations and will 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.

NOTE:
• When the fuel nozzle “clicks” or shuts off, the fuel tank is full.
• 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.

Loose Fuel Filler Cap Message

If the vehicle diagnostic system determines that the fuel filler cap is loose, improperly installed, or damaged, a gASCAP” message will display in the odometer or a “CHECK GASCAP” message will be displayed in the Electronic Vehicle Information Center (EVIC). Refer to “Electronic Vehicle Information Center” in “Understanding Your Instrument Panel” for further information. Tighten the fuel filler cap until a “clicking” sound is heard. This is an indication that the fuel filler cap is properly tightened. Refer to “Onboard Diagnostic System” in “Maintaining Your Vehicle” for further information.
