If the parking brake is off and the light remains on, have
the brake system inspected as soon as possible.
19. Full Time Indicator Light — If Equipped This light alerts the driver that the vehicle is in
the FULL TIME four–wheel drive mode, and

Should your vehicle run out of fuel, the fuel system must
be re-primed in order to start the engine. Factors such as
temperature, which affects the viscosity of the fuel, how
long the vehicle has been sitting and other factors will
influence how quickly the engine starts.
Re-Priming the Diesel Fuel System
The following procedure must be followed after com-
pletely running out of fuel.
1. Add a minimum of 2 gallons (7.57L) of diesel fuel to
the fuel tank.
2. Open the hood.
3. Depress the fuel-water separator knob 20 consecutive
times. 4. Turn the ignition to START and crank the engine a
maximum of 10 seconds. If the engine does not start,
repeat Step 3.
NOTE:
The engine will typically start within 10 sec-
onds; the engine will idle then stall, purging air from the
fuel lines and filter.

FUEL TANK FILLER CAP (GAS CAP)
CAUTION!
•To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
•DO NOT put gasoline in your diesel vehicle (if
equipped). If you accidentally put gasoline in
your vehicle, DO NOT start the engine. This will
cause damage to the fuel system. Have the fuel
system flushed.
The gas cap is located behind the fuel filler door, on the
left 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. When tightening the gas cap, tighten until 2 or 3 clicks
are heard to insure that the cap is properly seated.

Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“GAS CAP” message will be displayed in the odometer
(located on the instrument cluster). Replace, or tighten
the fuel filler cap properly to turn the message off (light
will time out). If the problem continues, the message will
appear the next time the vehicle is started. Refer to
“Onboard Diagnostic System — OBDII” in Section 7 of
this manual for more information. (See page 316 for more
information.)
CAUTION!
Damage to the fuel system or emission control
system could result from using an improper fuel
tank filler cap (gas cap). A poorly fitting cap could let
impurities into the fuel system.
WARNING!
•Never add fuel when the engine is running.
•Never have any smoking materials lit in or near
the vehicle when the fuel cap is removed or the
tank filled.
