WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could injure someone in the vehicle. Always
stow the jack parts and the extra tire and wheel in the
places provided.
7. Install wheel center cap (if equipped) and remove wheel blocks. Do not install chrome or aluminum wheel center
caps on the spare wheel. This may result in cap damage.
8. Lower the jack to its fully closed position. If the jack will not lower by turning the dial (thumbwheel) by hand, it
may be necessary to use the jack drive tube in order to
lower the jack. Stow the replaced tire, jack, and tools as
previously described.
9. Adjust the tire pressure when possible.
Hub Caps/Wheel Covers — If Equipped
The hub caps must be removed before raising the vehicle
off the ground.
CAUTION!
Use extreme caution when removing the front and rear
center caps. Damage can occur to the center cap and/or
the wheel if screwdriver type tools are used. A pulling
motion, not a pry off motion, is recommended to
remove the caps.
For single rear wheel (SRW) models, use the flat blade on
the end of the lug wrench to pull the hub cap off. Insert the
blade end into the pull off notch and carefully pull the hub
cap off with a back and forth motion.
On 3500 models with dual rear wheels (DRW), you must
first remove the hub caps. The jack handle driver has a
hook at one end that will fit in the pull off notch of the rear
hub caps. Position the hook and pull straight out on the
ratchet firmly. The hub cap should pop off. The wheel skins
can now be removed. For the front hub cap, use the flat
blade on the end of the lug wrench to pull the caps off. The
wheel skin can now be removed.
438 WHAT TO DO IN EMERGENCIES
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.
You must use the flat end of the lug wrench to pull off the
wheel skins. Locate the hub cap pull notches (2 notches on
each cap). Insert the flat tip completely and using a back
and forth motion, loosen the wheel skin. Repeat this
procedure around the tire until the skin pops off.
Replace the wheel skins first using a rubber mallet. When
replacing the hub caps, tilt the cap retainer over the lug nut
bolt circle and strike the high side down with a rubber
mallet. Be sure that the hub caps and wheel skins are firmly
seated around the wheel.
Dual Rear Wheels
Slots in the wheels will assist in properly orienting the
inner and outer wheels. Align these slots when assembling
the wheels for best access to the tire valve on the inner wheel. The tires of both dual wheels must be completely off
the ground when tightening to insure wheel centering and
maximum wheel clamping.
Dual wheel models require a special heavy-duty lug nut
tightening adapter (included with the vehicle) to correctly
tighten the lug nuts. Also, when it is necessary to remove
and install dual rear wheels, use a proper vehicle lifting
device.
NOTE:
When installing a spare tire (if equipped) as part of
a dual rear wheel end combination, the tire diameter of the
two individual tires must be compared. If there is a
significant difference, the larger tire should be installed in
a front location. The correct direction of rotation for dual
tire installations must also be observed.
It is recommended that wheel stud nuts be kept torqued to
specifications at all times. Torque wheel stud nuts to
specifications at each lubrication interval.
Wheel Nuts
All wheel nuts should be tightened occasionally to elimi-
nate the possibility of wheel studs being sheared or the bolt
holes in the wheels becoming elongated. This is especially
important during the first few hundred miles/kilometers
of operation to allow the wheel nuts to become properly

WHAT TO DO IN EMERGENCIES 439
set. All wheel nuts should first be firmly seated against the
wheel. The wheel nuts should then be tightened to recom-
mended torque. Tighten the wheel nuts to final torque in
increments. Progress around the bolt circle, tightening the
wheel nut opposite to the wheel nut just previously
tightened until final torque is achieved.
To Stow The Flat Or Spare — If Equipped
Refer to Upfitters Body Builders Guide for information on
stowing your spare tire (if equipped).
HOISTING
A conventional floor jack may be used at the jacking
locations. Refer to the graphics that show jacking locations.
However, a floor jack or frame hoist must never be used on
any other parts of the underbody.
CAUTION!
Never use a floor jack directly under the differential
housing of a loaded truck or damage to your vehicle
may result.
JUMP-STARTING PROCEDURES
If your vehicle has a discharged battery, it can be jump-
started using a set of jumper cables and a battery in another
vehicle or by using a portable battery booster pack. Jump-
starting can be dangerous if done improperly, so please
follow the procedures in this section carefully.
NOTE:When using a portable battery booster pack, follow
the manufacturer ’s operating instructions and precautions.
WARNING!
Do not attempt jump-starting if the battery is frozen. It
could rupture or explode and cause personal injury.
CAUTION!
Do not use a portable battery booster pack or any other
booster source with a system voltage greater than
12 Volts or damage to the battery, starter motor, alter-
nator or electrical system may occur.
440 WHAT TO DO IN EMERGENCIES
MAINTENANCE SCHEDULE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that service
is required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, extremely hot or cold
ambient temperatures, and E85 fuel usage will influence
when the “Oil Change Required” message is displayed.
Severe Operating Conditions can cause the change oil
message to illuminate as early as 3,500 miles (5,600 km)
since last reset. Have your vehicle serviced as soon as
possible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other than
your authorized dealer, the message can be reset by
referring to the steps described under “Instrument Cluster
Display” in “Understanding Your Instrument Panel” for
further information.Gasoline Engines:
Under no circumstances should oil change intervals exceed
8,000 miles (13,000 km), twelve months or 350 hours of
engine run time, whichever comes first. The 350 hours of
engine run or idle time is generally only a concern for fleet
customers.
Severe Duty:
Change Engine Oil at 4,000 miles (6,500 km) if the vehicle
is operated in a dusty and off road environment or is
operated predominately at idle or very low engine RPM’s.
This type of vehicle use is considered Severe Duty.
Once A Month Or Before A Long Trip:
•
Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual
wear or damage
• Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering and automatic transmis-
sion, and fill as needed
• Check function of all interior and exterior lights
