STARTING AND OPERATING

(Continued)
NOTE:
When the fuel nozzle “clicks” or shuts off,
the fuel tank is full.
Tighten the fuel filler cap about a quarter
turn until you hear one click. This is an
indication that the cap is properly tight-
ened.
If the fuel filler cap is not tightened properly,
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
malfunction, 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 tightened. 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.
REFUELING THE VEHICLE —
DIESEL
The fuel filler cap is located on the
passenger's side of the vehicle. If the fuel
filler cap is lost or damaged, be sure the
replacement cap is the correct one for this
vehicle.
