166 STARTING AND OPERATING
(Continued)
4. Fill the vehicle with fuel.
NOTE:
When the fuel nozzle “clicks” or shuts off, the fuel
tank is full.
Wait five seconds before removing the fuel nozzle
to allow excess fuel to drain from the nozzle.
5. Remove the fuel nozzle, reinstall fuel cap and close
fuel filler door.
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 prop-
erly tightened.
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 diagnostic 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 ENGINE
(IF EQUIPPED)
The fuel filler cap is located on the driver'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.
1. Open the fuel filler door.
Fuel Filler Door
WARNING!
Never have any smoking materials lit in or near the
vehicle when the fuel door is open or the tank is being
filled.
Never add fuel when the engine is running. This is in
violation of most state and federal fire regulations and
may cause the Malfunction Indicator Light to turn on.
A fire may result if fuel is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place fuel 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 aftermarket cap can
cause the Malfunction Indicator Light (MIL) to illumi-
nate, due to fuel vapors escaping from the system.
To avoid fuel spillage and overfilling, do not “top off
the fuel tank after filling.
CAUTION!
