TRAILER TOWINGIn this section you will find safety tips and
information on limits to the type of towing you
can reasonably do with your vehicle. Before
towing a trailer, carefully review this information
to tow your load as efficiently and safely as
possible.
To maintain warranty coverage, follow the re-
quirements and recommendations in this
manual concerning vehicles used for trailer
towing.
Common Towing DefinitionsThe following trailer towing related definitions
will assist you in understanding the following
information.
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your
vehicle. This includes driver, passengers,
cargo and trailer tongue weight. The total load
must be limited so that you do not exceed the
GVWR.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the
weight of all cargo, consumables and equip-
ment (permanent or temporary) loaded in or on
the trailer in its loaded and ready for operation 
condition.
The recommended way to measure GTW is to
put your fully loaded trailer on a vehicle scale.
The entire weight of the trailer must be sup-
ported by the scale.
Gross Combination Weight Rating (GCWR)
The GCWR is the total permissible weight of
your vehicle and trailer when weighed in com-
bination. NOTE:
The GCWR rating includes a 150 lbs (68 kg)
allowance for the presence of a driver.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front
and rear axles. Distribute the load over the front
and rear axles evenly. Make sure that you do
not exceed either front or rear GAWR.
WARNING!
It is important that you do not exceed the
maximum front or rear GAWR. A dangerous
driving condition can result if either rating is
exceeded. You could lose control of the ve-
hicle and have an accident.
Trailer Tongue Weight (TW)
The TW is the downward force exerted on the
hitch ball by the trailer. In most cases it should
not be more than 5% of the trailer load. You
must consider this as part of the load on your
vehicle.

ONBOARD DIAGNOSTIC SYSTEM –
OBD II
Your vehicle is equipped with a sophisticated
onboard diagnostic system called OBD II. This
system monitors the performance of the emis-
sions, engine, and automatic transmission con-
trol systems. When these systems are operat-
ing properly, your vehicle will provide excellent
performance and fuel economy, as well as
engine emissions well within current govern-
ment regulations.
If any of these systems require service, the
OBD II system will turn on the “Malfunction
Indicator Light” (MIL). It will also store diagnos-
tic codes and other information to assist your
service technician in making repairs. Although
your vehicle will usually be drivable and not
need towing, see your authorized dealer for
service as soon as possible.
CAUTION!
•Prolonged driving with the MIL on could
cause further damage to the emission con-
trol system. It could also affect fuel
economy and drivability. The vehicle must
be serviced before any emissions tests can
be performed.
• If the MIL is flashing while the engine is
running, severe catalytic converter damage
and power loss will soon occur. Immediate
service is required.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system
determines that the fuel filler cap is
loose, improperly installed, or
damaged, a loose gascap indica-
tor will display in the EVIC telltale
display area. Refer to “Electronic
Vehicle Information Center (EVIC)” in “Under-
standing Your Instrument Panel” for further in-
formation. Tighten the fuel filler cap properly
and press the SELECT button to turn off the message. If the problem continues, the mes-
sage will appear the next time the vehicle is
started.
A loose, improperly installed, or damaged fuel
filler cap may also turn on the Malfunction
Indicator Light (MIL).
REPLACEMENT PARTSUse of genuine MOPAR
parts for normal/
scheduled maintenance and repairs is highly
recommended to ensure the designed perfor-
mance. Damage or failures caused by the use
of non-MOPAR parts for maintenance and
repairs will not be covered by the manufactur-
er’s warranty.
MAINTENANCE PROCEDURESThe pages that follow contain the required
maintenance services determined by the engi-
neers who designed your vehicle.
Besides those maintenance items specified in
the fixed maintenance schedule, there are
other components which may require servicing
or replacement in the future.

•Or, disconnect the negative cable from the
battery.
• Anytime you store your vehicle, or keep it out
of service (i.e. vacation) for two weeks or
more, run the air conditioning system at idle
for about five minutes in the fresh air and
high blower setting. This will ensure ad-
equate system lubrication to minimize the
possibility of compressor damage when the
system is started again.

High Intensity Discharge Headlamps
(HID) – If Equipped
The headlamps are a type of high voltage
discharge tube. High voltage can remain in the
circuit even with the headlamp switch off and
the key removed. Because of this, you should
not attempt to service a headlamp bulb your-
self. If a headlamp bulb fails, take your
vehicle to an authorized dealer for service.
WARNING!
A transient high tension occurs at the bulb
sockets of High Intensity Discharge (HID)
headlamps when the headlamp switch is
turned ON. It may cause serious electrical
shock or electrocution if not serviced properly.
See your authorized dealer for service.
NOTE:
On vehicles equipped with High Intensity
Discharge (HID) headlamps , when the head-
lamps are turned on, there is a blue hue to
the lamps. This diminishes and becomes

MAINTENANCE SCHEDULE
Maintenance Schedule – Gasoline
Engine
The oil change indicator system will remind you
that it is time to take your vehicle in for sched-
uled maintenance.
On Electronic Vehicle Information Center
(EVIC) equipped vehicles “Oil Change Re-
quired” will be displayed in the EVIC and a
single chime will sound, indicating that an oil
change is necessary.
The oil change indicator message will illumi-
nate approximately 7,000 miles (11 200 km)
after the most recent oil change was per-
formed. Have your vehicle serviced as soon as
possible, within 500 miles (800 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
6 months since your last oil change even
if the oil change indicator message is
NOT illuminated. •
Change your engine oil more often if you
drive your vehicle off-road for an ex-
tended period of time.
• Under no circumstances should oil
change intervals exceed 7,500 miles
(12 000 km) or 6 months, whichever
comes first.
Your authorized dealer will reset the oil change
indicator message after completing the sched-
uled oil change. If this scheduled oil change is
performed by someone other than your autho-
rized dealer the message can be reset by
referring to the steps described under ”Elec-
tronic Vehicle Information Center” in “Under-
standing Your Instrument Panel” for further in-
formation.
At Each Stop for Fuel
• Check the engine oil level about 5 minutes
after a fully warmed engine is shut off.
