FUSES
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
WARNING!
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. Fail-
ure to use proper fuses may result in
serious personal injury, fire and/or prop-
erty damage.
• Before replacing a fuse, make sure that
the ignition is off and that all the other
services are switched off and/or disen-
gaged.
• If the replaced fuse blows again, contact
an authorized dealer.
• If a general protection fuse for safety
systems (air bag system, braking sys-
tem), power unit systems (engine sys-
tem, transmission system) or steering
WARNING!
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 descrip-
tion 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 Fuse Micro Fuse Description
F01 80 Amp Black –Rad Fan Control Module – If Equipped
F03 60 Amp Yellow –Rad Fan – If Equipped
F05 40 Amp Green –Compressor for Air Suspension – If Equipped
F06 40 Amp Green –Antilock Brakes/Electronic Stability Control Pump

NOTE:
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 di-
rectly off positive post which has a positive
(+)symbol on or around the post.
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.
1. Apply the parking brake, shift the auto- matic transmission into PARK and turn
the ignition to LOCK. 2. Turn off the heater, radio, and all unnec-
essary 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.
WARNING!
Do not allow vehicles to touch each other
as this could establish a ground connec-
tion and personal injury could result.
Jump Starting Procedure
WARNING!
Failure to follow this jump starting proce-
dure 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 ve-
hicle.
Connecting The Jumper Cables
1. Connect the positive (+)end of the jumper
cable to the positive (+)post of the dis-
charged 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.
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
219

WARNING!
personal injury. Only use the specific
ground point, do not use any other exposed
metal parts.
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.
CAUTION!
Do not connect jumper cable to any of the
fuses on the positive battery terminal. The
resulting electrical current will blow the
fuse.
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 nega-
tive (-)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 posi- tive (+)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.
CAUTION!
Accessories plugged into the vehicle
power outlets draw power from the vehi-
cle’s battery, even when not in use (i.e.,
cellular devices, etc.). Eventually, if
plugged in long enough without engine
operation, the vehicle’s battery will dis-
charge sufficiently to degrade battery life
and/or prevent the engine from starting.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission in NEUTRAL, but do not in-
crease the engine idle speed while prevent-
ing vehicle motion with the brakes.
NOTE:
There are steps that you can take to slow
down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the engine
cooling system and turning the A/C off can
help remove this heat.
• You can also turn the temperature control to maximum heat, the mode control to floor
and the blower control to high. This allows
the heater core to act as a supplement to
the radiator and aids in removing heat from
the engine cooling system.
