4500/5500 Models
These vehicles do not come equipped with a
jack.
NOTE:
Jacking and tire changing on 4500/
5500 models should be performed by an autho -
rized dealer, or knowledgeable service
personnel with the appropriate heavy duty
equipment, like a tire service company.
Preparations For Jacking

1. Park the vehicle on a firm, level surface. Avoid ice or slippery areas.

2. Place the gear selector into PARK. On four-wheel drive vehicles, shift the transfer
case to the 4L position.
3. Turn on the Hazard Warning flashers.
4. Apply the parking brake. 5. Turn the ignition OFF.
6. Block both the front and rear of the wheel
diagonally opposite the jacking position. For
example, if the driver’s front wheel is being
changed, block the passenger’s rear wheel.

Wheel Blocked

NOTE:
Passengers should not remain in the vehicle
when the vehicle is being jacked.
Jacking Instructions 4500 And 5500 Series
WARNING!
Do not attempt to change a tire on the side of
the vehicle close to moving traffic. Pull far
enough off the road to avoid being hit when
operating the jack or changing the wheel.
WARNING!
Carefully follow these tire changing warnings
to help prevent personal injury or damage to
your vehicle:
Always park on a firm, level surface as far
from the edge of the roadway as possible
before raising the vehicle.
Turn on the Hazard Warning flashers.
Apply the parking brake firmly and set the
transmission in PARK.
Block the wheel diagonally opposite the
wheel to be raised.
Never start or run the engine with the
vehicle on a jack.
Do not let anyone sit in the vehicle when it
is on a jack.
Do not get under the vehicle when it is on a
jack. If you need to get under a raised
vehicle, take it to a service center where it
can be raised on a lift.

320IN CASE OF EMERGENCY
Preparations For Jump Start
The battery in your vehicle is located in the front
of the engine compartment, behind the left
headlight assembly.
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 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

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.
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.

322IN CASE OF EMERGENCY
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.
GEAR SELECTOR OVERRIDE — 6–SPEED
TRANSMISSION
If a malfunction occurs and the gear selector
cannot be moved out of the PARK position, you
can use the following procedure to temporarily
move the gear selector:

1. Turn the engine OFF.

2. Firmly apply the parking brake.
3. Tilt the steering wheel to the full up position.
4. Press and maintain firm pressure on the
brake pedal. 5. Insert a screwdriver or similar tool into the
access port (ringed circle) on the bottom of
the steering column, and push and hold the
override release lever up.

Gear Selector Override Access Port Location Gear Selector Override Access Port
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam coming
from under the hood, do not open the hood
until the radiator has had time to cool. Never
try to open a cooling system pressure cap
when the radiator or coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could
damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop the
vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops
back into the normal range. If the pointer
remains on HOT (H), and you hear continuous
chimes, turn the engine off immediately and
call for service.

6. Move the gear selector to the NEUTRAL position.
7. The vehicle may then be started in NEUTRAL.
MANUAL PARK RELEASE — 8 – SPEED
TRANSMISSION
To push or tow the vehicle in cases where the
transmission will not shift out of PARK (such as
a depleted battery), a Manual Park Release is
available.
Manual Park Release Cover
Manual Park Release Pull Strap

WARNING!
Always secure your vehicle by fully applying
the parking brake before activating the
Manual Park Release. In addition, you should
be seated in the driver’s seat with your foot
firmly on the brake pedal when activating the
Manual Park Release. Activating the Manual
Park Release will allow your vehicle to roll
away if it is not secured by the parking brake,
or by proper connection to a tow vehicle.
Activating the Manual Park Release on an
unsecured vehicle could lead to serious injury
or death for those in or around the vehicle.

IN CASE OF EMERGENCY325
NOTE:
For trucks equipped with an 8–speed trans -
mission, shifts between DRIVE and REVERSE
can only be achieved at wheel speeds of
5 mph (8 km/h) or less. Whenever the trans -
mission remains in NEUTRAL (N) for more
than two seconds, you must press the brake
pedal to engage DRIVE or REVERSE.
Push the “ESC OFF” switch, to place the Elec -
tronic Stability Control (ESC) system in
“Partial Off” mode, before rocking the
vehicle. Refer to “Electronic Brake Control
System” in “Safety” for further information.
Once the vehicle has been freed, push the
“ESC OFF” switch again to restore “ESC On”
mode.
WARNING!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause damage, or even failure, of the axle
and tires. A tire could explode and injure
someone. Do not spin your vehicle's wheels
faster than 30 mph (48 km/h) or for longer
than 30 seconds continuously without
stopping when you are stuck and do not let
anyone near a spinning wheel, no matter
what the speed.
CAUTION!
Racing the engine or spinning the wheels
may lead to transmission overheating and
failure. Allow the engine to idle with the
transmission in NEUTRAL for at least one
minute after every five rocking-motion
cycles. This will minimize overheating and
reduce the risk of transmission failure
during prolonged efforts to free a stuck
vehicle.
When “rocking” a stuck vehicle by shifting
between DRIVE and REVERSE, do not spin
the wheels faster than 15 mph (24 km/h), or drivetrain damage may result.
Revving the engine or spinning the wheels
too fast may lead to transmission over -
heating and failure. It can also damage the
tires. Do not spin the wheels above 30 mph
(48 km/h) while in gear (no transmission
shifting occurring).

TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled vehicle using a commercial towing service. If the transmission and drivetrain are operable,
disabled vehicles may also be towed as described under “Recreational Towing” in the “Starting And Operating” section.
Proper towing or lifting equipment is required to
prevent damage to your vehicle. Use only tow
bars and other equipment designed for this
purpose, following equipment manufacturer’s
instructions. Use of safety chains is mandatory.
Attach a tow bar or other towing device to main
structural members of the vehicle, not to
bumpers or associated brackets. State and
local laws regarding vehicles under tow must be
observed. If you must use the accessories (wipers,
defrosters, etc.) while being towed, the ignition
must be in the ON/RUN mode, not the ACC
mode.
