WARNING! (Continued)
•Never add fuel when the engine is running. This is
in violation of most state and federal fire regula-
tions and doing so will cause the malfunction
indicator light 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:
•Tighten the gas cap until you hear a “clicking” sound.
This is an indication that the gas cap is tightened
properly. The Malfunction Indicator Light (MIL) in the
instrument cluster may turn on if the gas cap is not
secured properly. Make sure that the gas cap is tight-
ened each time the vehicle is refueled.
•When the fuel nozzle “clicks” or shuts off, the fuel
tank is full.
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 be displayed in the Odometer/
Trip Odometer in the instrument cluster. Refer to “Instru-
ment Cluster Description” in “Understanding Your In-
strument Panel” for further information. Tighten the fuel
filler cap properly and press the odometer/trip odometer
reset button to turn the message off. If the problem
continues, 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
light off. Refer to “Onboard Diagnostic System” in
“Maintaining Your Vehicle” for further information.

STARTING AND OPERATING 243

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). OBD
II will also store diagnostic codes and other information
to assist an authorized service technician in making
repairs. Although your vehicle will usually be drivable
and not need towing, see your authorized dealer for
service as soon as possible.
Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is loose, improperlyinstalled, or damaged. A “gASCAP” message will be
displayed in the instrument cluster. Tighten the gas cap
until a
clicking sound is heard. This is an indication that
the gas cap is properly tightened. Press 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
light off.
