IN CASE OF EMERGENCY353
For 2500/3500 Single Rear Wheel (SRW)
models, use the flat end of the lug wrench to
hook and pull off the hub cap. Find the opening
in the hub cap, insert the lug wrench, and pull
off the cap. If you need to pry against the wheel,
protect the wheel surface.

Lug Wrench Insertion Location — Hub Cap

On 3500 models with Dual Rear Wheels (DRW),
you must first remove the hub caps—use the
procedure noted for the single rear wheel. For
the wheel covers (wheel skins), insert the flat
end of the lug wrench between the outer edge
of the wheel cover and the wheel. Pry against
the wheel to remove the wheel cover. Repeat
this procedure around the wheel until the cover
pops off.
Lug Wrench Insertion Location — Wheel Cover

Replace the wheel covers using a rubber mallet
to ease the installation. Align the wheel cover
vent holes to the wheel vent holes. Tap on the
wheel cover as needed to firmly seat it evenly
around the wheel.FUSES
CAUTION!
Use a pulling motion to remove the hub
cap. Do not use a twisting motion when
removing the hub cap, damage to the hub
cap; finish may occur.
The rear hub caps on the dual rear wheel
has two pull off notches. Make sure that the
hook of the jack handle driver is located
squarely in the cap notch before attempting
to pull off.
WARNING!
When replacing a blown fuse, always use
an appropriate replacement fuse with the
same amp rating as the original fuse. Never
replace a fuse with another fuse of higher
amp rating. Never replace a blown fuse with
metal wires or any other material. Do not
place a fuse inside a circuit breaker cavity
or vice versa. Failure to use proper fuses
may result in serious personal injury, fire
and/or property damage.
Before replacing a fuse, make sure that the
ignition is off and that all the other services
are switched off and/or disengaged.
If the replaced fuse blows again, contact an
authorized dealer.
If a general protection fuse for safety
systems (air bag system, braking system),
power unit systems (engine system, trans -
mission system) or steering system blows,
contact an authorized dealer.

Power Distribution Center
The Power Distribution Center is located in the
engine compartment near the battery. This
center contains cartridge fuses, micro fuses,
relays, and circuit breakers. 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.

IN CASE OF EMERGENCY363
Preparations For Jump Start
The battery in your vehicle is located in the front
of the engine compartment, behind the driver
side headlight assembly.
NOTE:
If you have a diesel engine, you may have two
batteries, however jump start off the driver
side battery.
The positive battery post may be covered with
a protective cap if equipped. Lift up on the
cap to gain access to the positive battery
post. Do not jump off fuses. Only jump
directly off positive post which has a positive
(+) symbol on or around the post.

Positive Battery Post
1. Apply the parking brake, shift the auto
-
matic transmission into PARK and turn the
ignition OFF.

2. Turn off the heater, radio, and all unneces -
sary electrical accessories.
3. If using another vehicle to jump start the battery, park the vehicle within the jumper
cables’ reach, apply the parking brake and
make sure the ignition is OFF.
Jump Starting Procedure
Connecting The Jumper Cables
WARNING!
Take care to avoid the radiator cooling fan
whenever the hood is raised. It can start
anytime the ignition switch is ON. You can
be injured by moving fan blades.
Remove any metal jewelry such as rings,
watch bands and bracelets that could
make an inadvertent electrical contact. You
could be seriously injured.
Batteries contain sulfuric acid that can
burn your skin or eyes and generate
hydrogen gas which is flammable and
explosive. Keep open flames or sparks
away from the battery.
WARNING!
Do not allow vehicles to touch each other as
this could establish a ground connection and
personal injury could result.
WARNING!
Failure to follow this jump starting procedure
could result in personal injury or property
damage due to battery explosion.
CAUTION!
Failure to follow these procedures could
result in damage to the charging system of
the booster vehicle or the discharged vehicle.

364IN CASE OF EMERGENCY

1. Connect the positive
(+) end of the jumper
cable to the positive (+)
post of the
discharged vehicle.

NOTE:
Do not jump off fuses. Only jump directly off
positive post.
2. Connect the opposite end of the positive (+)
jumper cable to the positive (+) post of the
booster battery.
3. Connect the negative (-) end of the jumper
cable to the negative (-) post of the booster
battery.
4. Connect the opposite end of the negative (-)
jumper cable to a good engine ground
(exposed metal part of the discharged vehicle’s engine) away from the battery and
the fuel injection system.
5. Start the engine in the vehicle that has the booster battery, let the engine idle a few
minutes, and then start the engine in the
vehicle with the discharged battery.
6. Once the engine is started, remove the jumper cables in the reverse sequence. Disconnecting The Jumper Cables

1. Disconnect the negative
(-)

end of the
jumper cable from the engine ground of
the vehicle with the discharged battery.

2. Disconnect the opposite end of the negative (-) jumper cable from the negative (-) post of
the booster battery.
3. Disconnect the positive (+) end of the
jumper cable from the positive (+) post of
the booster battery.
4. Disconnect the opposite end of the positive (+) jumper cable from the positive (+) post
of the vehicle with the discharged battery.
If frequent jump starting is required to start your
vehicle you should have the battery and
charging system inspected at an authorized
dealer.
WARNING!
Do not connect the jumper cable to the
negative (-) post of the discharged battery.
The resulting electrical spark could cause the
battery to explode and could result in
personal injury. Only use the specific ground
point, do not use any other exposed metal
parts.
CAUTION!
Do not connect jumper cable to any of the
fuses on the positive battery terminal. The
resulting electrical current will blow the fuse.
