power tools is not recommended and can damage the
winch.Tire Changing Procedure
WARNING!
•
Getting under a jacked-up vehicle is dangerous.
The vehicle could slip off the jack and fall on you.
You could be crushed. Never get any part of your
body under a vehicle that is on a jack. Never start
or run the engine while the vehicle is on a jack. If
you need to get under a raised vehicle, take it to an
authorized service center where it can be raised on
a lift.

WARNING! (Continued)
•
Do not raise this vehicle using a bumper jack. The
jack is designed as a tool for changing tires on this
vehicle only. It is not recommended that the jack
be used for service purposes or to lift more than
one wheel at a time.
Preparations1. Park the vehicle on a firm, level surface. Avoid ice or
slippery areas.
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 the danger of being hit when
operating the jack or changing the wheel.
2. Set the parking brake.

include cleaning of the condenser fins and a performance
test. Drive belt tension should also be checked at this
time.
WARNING!
•
Use only refrigerants and compressor lubricants
approved by the manufacturer for your air condi-
tioning system. Some unapproved refrigerants are
flammable and can explode, injuring you. Other
unapproved refrigerants or lubricants can cause
the system to fail, requiring costly repairs. Refer to
Section 3 of the Warranty Information book for
further warranty information.
•
The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal
injury or damage to the system, adding refrigerant
or any repair requiring lines to be disconnected
should be done by an experienced repairman.NOTE:
Use only manufacturer approved A/C System
Sealers, Stop Leak Products, Seal Conditioners, Compres-
sor Oil, or Refrigerants.
Refrigerant Recovery and RecyclingR-134a air conditioning refrigerant is a hydrofluoro-
carbon (HFC) that is endorsed by the Environmental
Protection Agency (EPA) and is an ozone-saving product.
However, the manufacturer recommends that air condi-
tioning service be performed by authorized dealers or
other service facilities using recovery and recycling
equipment.Front Prop Shaft Lubrication — 2500/3500 (4X4)
ModelsLubricate the front driveshaft grease fitting at each oil
change. Refer to the “Maintenance Schedule” in Section 8
for the proper maintenance intervals. Use MOPAR Type
MS-6560 (lithium-based grease), or equivalent.

Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing CO, refer
to “Exhaust Gas” in the “Safety Tips” section of this
manual.The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device.
Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.

MAINTENANCE SCHEDULEThe oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
The “Change Oil” message will flash in the instrument
cluster odometer and a single chime will sound, indicat-
ing that an oil change is necessary.
Based on engine operation conditions the oil change
indicator message will illuminate, this means that service
is required for your vehicle. Have your vehicle serviced
as soon as possible, within the next 500 miles (805 km).
NOTE:•
The oil change indicator message will not monitor the
time since the last oil change. Change your vehicles oil
if it has been six months since your last oil change even
if the oil change indicator message is NOT illumi-
nated.
•
Change your engine oil more often if you drive your
vehicle off-road for an extended period of time.
•
Under no circumstances should oil change intervals
exceed 6,000 miles (10 000 km) or six months, which-
ever comes first.
Your dealer will reset the oil change indicator message
after completing the scheduled oil change. If this sched-
uled oil change is performed by someone other than your
dealer the message can be reset by referring to the steps
described under “Odometer/Trip Odometer” under “In-
strument Cluster Description” in Section 4 of this
manual.
