SCHEDULED SERVICING
Scheduled Servicing — Gasoline Engine
The scheduled services listed in this manual
must be done at the times or mileages speci-
fied to protect your vehicle warranty and
ensure the best vehicle performance and re-
liability. More frequent maintenance may be
needed for vehicles in severe operating con-
ditions, such as dusty areas and very short
trip driving. Inspection and service should
also be done anytime a malfunction is sus-
pected.
The oil change indicator system will remind
you that it is time to take your vehicle in for
scheduled maintenance.
An “Oil Change Required” will be displayed
in the instrument cluster 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 notmonitor the time since the last oil change.
Change your vehicle’s oil if it has been
12 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 extended
period of time.
• Under no circumstances should oil change intervals exceed 7,500 miles (12,000 km)
or 12 months, whichever comes first.
Your authorized dealer will reset the oil
change indicator message after completing
the scheduled oil change. If this 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 “Get-
ting To Know Your Instrument Panel” for
further information. Once A Month Or Before A Long Trip
• Check engine oil level.
• Check windshield washer fluid level.
• Check tire pressure and look for unusual
wear or damage. Rotate tires at the first
sign of irregular wear, even if it occurs
before the oil indicator system turns on.
• Check the fluid levels of the coolant reser- voir and brake master cylinder, fill as
needed.
• Check function of all interior and exterior lights.

Scheduled Servicing — Diesel Engine
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 fre-
quent short-trips, trailer tow, extremely hot or
cold ambient temperatures will influence
when the “Oil Change Required” message is
displayed. Severe Operating Conditions can
cause the change oil message to illuminate
as earlier than specified. Have your vehicle
serviced as soon as possible, within the next
500 miles (805 km).
To help you have the best driving experience
possible, the manufacturer has identified the
specific vehicle maintenance service inter-
vals that are required to keep your vehicle
operating properly and safely. The manufacturer recommends that these
maintenance intervals be performed at your
selling dealer. The technicians at your deal-
ership know your vehicle best, and have ac-
cess to factory trained information, genuine
Mopar parts, and specially designed elec-
tronic and mechanical tools that can help
prevent future costly repairs.
The maintenance intervals shown should be
performed as indicated in this section.
NOTE:
•
The actual interval for changing the oil and
replacing the engine oil filter depends on the
vehicle usage conditions, it is signaled by the
warning light or message (if present) in the
instrument panel. It should not exceed
12,500 miles (20,000 km) or 12 months.
• Flush and replace the engine coolant at

tire system for leaks. DO NOT REMOVE THE
COOLANT PRESSURE CAP WHEN THE
COOLING SYSTEM IS HOT.
Adding Washer Fluid
The windshield and rear window washers
share the same fluid reservoir. The fluid res-
ervoir is located in the front of the engine
compartment. Be sure to check the fluid level
in the reservoir at regular intervals. Fill the
reservoir with windshield washer solvent (not
radiator antifreeze) and operate the system
for a few seconds to flush out the residual
water.
When refilling the washer fluid reservoir, take
some washer fluid and apply it to a cloth or
towel and wipe clean the wiper blades, this
will help blade performance.
To prevent freeze-up of your windshield
washer system in cold weather, select a solu-
tion or mixture that meets or exceeds the
temperature range of your climate. This rat-
ing information can be found on most washer
fluid containers.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite
and burn you. Care must be exercised
when filling or working around the washer
solution.
Brake System
In order to assure brake system performance,
all brake system components should be in-
spected periodically. Refer to the “Mainte-
nance Plan” in this section for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your
foot resting or riding on the brake pedal
can result in abnormally high brake tem-
peratures, excessive lining wear, and pos-
sible brake damage. You would not have
your full braking capacity in an emergency.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should
be checked whenever the vehicle is serviced,
or immediately if the brake system warning
light is on. If necessary, add fluid to bring
level within the designated marks on the side
of the reservoir of the brake master cylinder.
Be sure to clean the top of the master cylin-
der area before removing cap. With disc
brakes, fluid level can be expected to fall as
the brake pads wear. Brake fluid level should
be checked when pads are replaced. If the
brake fluid is abnormally low, check the sys-
tem for leaks.
Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for further information.
WARNING!
• Use only manufacturer's recommendedbrake fluid. Refer to “Fluids And Lubri-
cants” in “Technical Specifications” for
further information. Using the wrong
type of brake fluid can severely damage
your brake system and/or impair its per-
formance. The proper type of brake fluid

Tread Wear Indicators
Tread wear indicators are in the original
equipment tires to help you in determining
when your tires should be replaced.
These indicators are molded into the bottom
of the tread grooves. They will appear as
bands when the tread depth becomes a
1/16 of an inch (1.6 mm). When the tread is
worn to the tread wear indicators, the tire
should be replaced. Refer to “Replacement
Tires” in this section for further information.
Life Of Tire
The service life of a tire is dependent upon
varying factors including, but not limited to:
• Driving style.
• Tire pressure - Improper cold tire inflationpressures can cause uneven wear patterns
to develop across the tire tread. These ab-
normal wear patterns will reduce tread life,
resulting in the need for earlier tire replace-
ment.
• Distance driven.
• Performance tires, tires with a speed rating of V or higher, and Summer tires typically
have a reduced tread life. Rotation of these
tires per the vehicle scheduled mainte-
nance is highly recommended.
WARNING!
Tires and the spare tire should be replaced
after six years, regardless of the remaining
tread. Failure to follow this warning can
result in sudden tire failure. You could lose
control and have a collision resulting in
serious injury or death. Keep dismounted tires in a cool, dry place
with as little exposure to light as possible.
Protect tires from contact with oil, grease,
and gasoline.
Replacement Tires
The tires on your new vehicle provide a bal-
ance of many characteristics. They should be
inspected regularly for wear and correct cold
tire inflation pressures. The manufacturer
strongly recommends that you use tires
equivalent to the originals in size, quality and
performance when replacement is needed.
Refer to the paragraph on “Tread Wear Indi-
cators” in this section. Refer to the Tire and
Loading Information placard or the Vehicle
Certification Label for the size designation of
your tire. The Load Index and Speed Symbol
for your tire will be found on the original
equipment tire sidewall.
It is recommended to replace the two front
tires or two rear tires as a pair. Replacing just
one tire can seriously affect your vehicle’s
handling. If you ever replace a wheel, make
sure that the wheel’s specifications match
those of the original wheels.

tires. Rotation will increase tread life, help to
maintain mud, snow, and wet traction levels,
and contribute to a smooth, quiet ride.
Refer to the “Maintenance Plan” for the
proper maintenance intervals. The reasons
for any rapid or unusual wear should be
corrected prior to rotation being performed.
The suggested Front Wheel Drive (FWD) rota-
tion method is the “forward cross” shown in
the following diagram. This rotation pattern
does not apply to some directional tires that
must not be reversed.
The suggested Four Wheel Drive (4WD) Tire
rotation method is the “rearward cross”
shown in the following diagram.
CAUTION!
Proper operation of four-wheel drive ve-
hicles depends on tires of equal size, type
and circumference on each wheel. Any
difference in tire size can cause damage to
the power transfer unit. Tire rotation
schedule should be followed to balance
tire wear.
STORING THE VEHICLE
If the vehicle should remain stationary for
more than a month, observe the following
precautions:
• Park your vehicle in a covered, dry andpossibly airy location the windows open
slightly. • Check that the Electric Park Brake is not
engaged.
• Disconnect the negative (-) terminal from the battery post and be sure that the battery
is fully charged. During storage check bat-
tery charge quarterly.
• If you do not disconnect the battery from the electrical system, check the battery
charge every 30 days.
• Clean and protect the painted parts by applying protective waxes.
• Clean and protect polished metal parts by applying protective waxes.
• Apply talcum powder to the front and rear wiper blades and leave raised from the
glass.
• Cover the vehicle with an appropriate cover taking care not to damage the painted sur-
face by dragging across dirty surfaces. Do
not use plastic sheeting which will not allow
the evaporation of moisture present on the
surface of the vehicle.
• Inflate the tires at a pressure of +7.25 psi (+0.5 bar) higher than recommended on
the tire placard and check it periodically.Front Wheel Drive (FWD) Tire Rotation

Leather Parts
Your leather upholstery can be best preserved
by regular cleaning with a damp soft cloth.
Small particles of dirt can act as an abrasive
and damage the leather upholstery and
should be removed promptly with a damp
cloth. Care should be taken to avoid soaking
your leather upholstery with any liquid.
Please do not use polishes, oils, cleaning
fluids, solvents, detergents, or ammonia-
based cleaners to clean your leather uphol-
stery. Application of a leather conditioner is
not required to maintain the original condi-
tion.
NOTE:
If equipped with light colored leather, it
tends to show any foreign material, dirt, and
fabric dye transfer more so than darker col-
ors. The leather is designed for easy cleaning.
CAUTION!
Do not use Alcohol and Alcohol-based
and/or Ketone based cleaning products to
clean leather seats, as damage to the seat
may result.
Glass Surfaces
All glass surfaces should be cleaned on a
regular basis with any commercial
household-type glass cleaner. Never use an
abrasive type cleaner. Use caution when
cleaning the inside rear window equipped
with electric defrosters or windows equipped
with radio antennas. Do not use scrapers or
other sharp instruments that may scratch the
elements.
When cleaning the rear view mirror, spray
cleaner on the towel or cloth that you are
using. Do not spray cleaner directly on the
mirror.
