WARNING!
•Always fully apply the parking brake when leav-
ing your vehicle, or it may roll and cause damage
or injury. Also be certain to leave an automatic
transmission in Park, a manual transmission in
Reverse or first gear. Failure to do so may allow
the vehicle to roll and cause damage or injury.
•Leaving children in a vehicle unattended is dan-
gerous for a number of reasons. A child or others
could be injured. Children should be warned not
to touch the parking brake or the gear selector
lever. Don’t leave the keys in the ignition. A child
could operate power windows, other controls, or
move the vehicle.
•Be sure the parking brake is fully disengaged
before driving, failure to do so can lead to brake
problems due to excessive heating of the rear
brakes.
When parking on a hill, turn the front wheels toward the
curb on a downhill grade and away from the curb on an
uphill grade.
The parking brake should always be applied whenever
the driver is not in the vehicle.
BRAKE SYSTEM
If power assist is lost for any reason (for example,
repeated brake applications with the engine off), the
brakes will still function. However, you will experience a
substantial increase in braking effort to stop the vehicle.
If either the front or rear hydraulic systems lose normal
capability, the remaining system will still function with
some loss of overall braking effectiveness. This will be
evident by increased pedal travel during application,
greater pedal force required to slow or stop, and activa-
tion of the BRAKE warning lamp and the ABS lamp (if
equipped) during brake use.

WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.
Priming if the engine has run out of fuel
1. Add a substantial quantity of fuel to the tank 5 to 10
gallons (19 to 38L).
2. Crank the engine for 1 to 2 seconds. If the engine does
not start, then release the key or starter button back to the
RUN position (do not turn the key back to the OFF
position). The electric fuel transfer pump will continue to
run and purge air from the system for about 20 seconds.
After 20 seconds, attempt to start the engine again.
3. Start the engine using the Normal Starting Procedure.4. Repeat the procedure if the engine does not start.
CAUTION!
Do not engage the starter motor for more than 15
seconds at a time. Allow two minutes between the
cranking intervals.
NOTE:The engine may run rough until the air is forced
from all the fuel lines.

place and for the position indicator lights to be operable.
If the key in not ON, the shift will not take place and no
position indicator lights will be on or flashing.NOTE:Flashing neutral (N) position indicator light
indicates that shift requirements have not been met.
CAUTION!
Damage to the transmission may occur if the trans-
mission is shifted into Park (P) with the transfer case
in Neutral (N) and the engine RUNNING. With the
transfer case in Neutral (N) ensure that the engine is

TOWING A DISABLED VEHICLE
Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other
equipment designed for the purpose, following equip-
ment manufacturer’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing device to
the main structural members of the vehicle—not to
bumpers or associated brackets. State and local laws
applying to vehicles under tow must be observed.
4-Wheel- Drive Vehicles
CAUTION!
To avoid damage to the transfer case while towing,
always use one of the following methods.
NOTE:The Transfer Case must be in the neutral posi-
tion, and the transmission must be in Park (Automatic
Transmission), or in gear (Manual Transmission) to tow a
4WD vehicle with one end of the vehicle raised.
The manufacturer recommends towing with all wheels
OFFthe ground. Acceptable methods are to tow vehicle
on a flatbed or with one end of vehicle raised and the
opposite end on a towing dolly.
2–Wheel- Drive Vehicles
Provided that the transmission is operable, tow with the
transmission in Neutral and the ignition key in the OFF
position along with the front wheels raised and the rear
wheels on the ground. Speed must not exceed 30 mph (50
km/h) and distance must not exceed 15 miles (25 km).
368 WHAT TO DO IN EMERGENCIES

CAUTION!
Do not drain the fuel/water separator filter when the
engine is running.
Drain a small amount from the fuel/water separator
filter periodically or when the WATER IN FUEL indicator
lamp is on. Pull outward on the drain valve lever, located
on the side of the filter, and allow any accumulated water
to drain. Hold the drain valve open until all water and
contaminants have been removed. Close the drain release
valve, by returning it to the inward position, when clean
fuel is visible.
NOTE:The Fuel / Water separator drain valve is
identified by its yellow handle and is located on the
inboard side of the fuel filter housing.If more than a couple ounces of fuel has been drained,
follow the directions below for “Priming if the engine has
run out of fuel.”
WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.
Priming if the engine has run out of fuel
1. Add a substantial quantity of fuel to the tank 5 to 10
gallons (19L to 38L).
2. Crank the engine for 1 to 2 seconds. If the engine does
not start, then release the key or starter button back to the
RUN position (do not turn the key back to the OFF
position). The electric fuel transfer pump will continue to

1. Disconnect the battery negative (-) cable before remov-

2. Use specified fuses only.
3. Always properly reinstall the cover.VEHICLE STORAGE
If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to mini-
mize the drain on your vehicle’s battery:
•Disconnect the Ignition-Off Draw fuse (I.O.D.) fuse
located in the Integrated Power Module, located in the
engine compartment. The I.O.D. cavity includes a
snap-in retainer that allows the fuse to be discon-
nected, without removing it from the fuse block.
•The electronic shift transfer case should be placed in
the 4HI mode and kept in this position to minimize the
battery drain.
•As an alternative to the above steps you may, discon-
nect the negative cables from both batteries.
NOTE:When reinstalling the IOD fuse, the gages in the
Instrument Cluster will do a full sweep, when the
ignition key is cycled to RUN. This is a normal condition.
