CAUTION!
Use the Jump Start Procedure only when the charge
indicator (if equipped) in both batteries is dark in the
center. Do not attempt jump starting when either
battery charge indicator (if equipped) is bright or
yellow. If charge indicator (if equipped) has a green
dot in the center, failure to start is not due to a
discharged battery and cranking system should be
checked.
1. Attach one jumper cable to the positive terminal of
booster battery and the other end of the same cable to the
positive terminal of the discharged battery.
WARNING!
Do not permit vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
400 WHAT TO DO IN EMERGENCIES

2. Connect one end of the other jumper cable to negative
(-) post of booster battery. Connect the other end of the
jumper cable to a good ground on the engine block of the
vehicle with the discharged battery. Make sure a good
connection is made, free of dirt and grease.
WARNING!
•Do not connect the cable to the negative post of the
discharge battery. The resulting electrical spark
could cause the battery to explode.
•During cold weather when temperatures are be-
low freezing point, electrolyte in a discharged
battery may freeze. Do not attempt jump starting
because the battery could rupture or explode. The
battery temperature must be brought up above
freezing point before attempting jump start.3. Take care that the clamps from one cable do not
inadvertently touch clamps from the other cable. Do not
lean over the battery when making connection. The
negative connection must provide good electrical con-
ductivity and current carrying capacity.
4. After the engine is started or if the engine fails to start,
cables must be disconnected in the following order:
a. Disconnect the negative cable at the engine ground.
b. Disconnect the negative cable at the negative post
on booster battery.
c. Disconnect the cable from the positive post of both
batteries.

WARNING!
Any procedure other than above could result in:
1. Personal injury caused by electrolyte squirting out
the battery vent;
2. Personal injury or property damage due to battery
explosion;
3. Damage to charging system of booster vehicle or
of immobilized vehicle.
With Portable Starting Unit
There are many types of these units available. Follow the
manufacturer’s instructions for necessary precautions
and operation.
CAUTION!
It is very important that the starting unit operating
voltage does not exceed 12 Volts D.C. or damage to
battery, starter motor, alternator, or electrical system
may occur.
FREEING A STUCK VEHICLE
If vehicle becomes stuck in snow, sand, or mud, it can
often be moved by a rocking motion. Move the gear
selector rhythmically between DRIVE and REVERSE
(automatic transmissions) and between 1st and RE-
VERSE (manual transmissions), while applying slight
pressure to the accelerator.
In general, the least amount of accelerator pedal pressure to
maintain the rocking motion without spinning the wheels
or racing the engine is most effective. Racing the engine or
spinning the wheels, due to the frustration of not freeing
402 WHAT TO DO IN EMERGENCIES

The PCM derates the engine in order to limit the likeli-
hood of permanent damage to the aftertreatment system.
If this condition is not corrected and a dealer service is
not performed, extensive exhaust aftertreatment damage
can occur. In order to correct this condition it will be
necessary to have the truck serviced by your local
authorized dealer.
Maintenance Free Batteries
The top of the maintenance free batteries are perma-
nently sealed. You will never have to add water, nor is
periodic maintenance required.
NOTE:Replacement batteries should both be of equal
capacity to prevent damage to the vehicle’s charging
system.
WARNING!
•Battery fluid is a corrosive acid solution and can
burn or even blind you. Don’t allow battery fluid
to contact your eyes, skin or clothing. Don’t lean
over a battery when attaching clamps. If acid
splashes in eyes or on skin, flush the area imme-
diately with large amounts of water.
•Battery gas is flammable and explosive. Keep
flame or sparks away from the battery. Don’t use a
booster battery or any other booster source with an
output greater than 12 volts. Don’t allow cable
clamps to touch each other.
•Battery posts, terminals and related accessories
contain lead and lead compounds. Wash hands
after handling.

CAUTION!
•It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post and the negative cable is attached to
the negative post. Battery posts are marked (+)
positive and negative (-) and identified on the
battery case.
•If a “fast charger” is used while battery is in
vehicle, disconnect both vehicle battery cables
before connecting the charger to battery. Do not
use a “fast charger” to provide starting voltage.
Battery Blanket Usage
A battery loses 60% of its cranking power as the battery
temperature decreases to 0°F (-18°). For the same de-
crease in temperature, the engine requires twice as much
power to crank at the same RPM. The use of 120 VAC
powered battery blankets will greatly increase starting
capability at low temperatures. Suitable battery blankets
are available from your authorized Mopardealer.
Air Conditioner Maintenance
For best possible performance, your air conditioner
should be checked and serviced by an Authorized Dealer
at the start of each warm season. This service should
include cleaning of the condenser fins and a performance
test. Drive belt tension should also be checked at this
time.

FUSES (INTEGRATED POWER MODULE)
An integrated Power Module is located in the engine
compartment near the battery. This center contains car-
tridge fuses and mini fuses. A description of each fuse
and component may be stamped on the inside cover
otherwise the cavity number of each fuse is stamped on
the inside cover that corresponds to the following chart.Cavity Cartridge

CAUTION!
•When installing the Integrated Power Module
cover, it is important to ensure the cover is prop-
erly positioned and fully latched. Failure to do so
may allow water to get into the Integrated Power
Module, and possibly result in a electrical system
failure.
•When replacing a blown fuse, it is important to
use only a fuse having the correct amperage rating.
The use of a fuse with a rating other than indicated
may result in a dangerous electrical system over-
load. If a properly rated fuse continues to blow, it
indicates a problem in the circuit that must be
corrected.
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.
