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 1/16 inch (2 mm). When the tread is worn to the
tread wear indicators, the tire should be replaced.
Many states have laws requiring tire replacement at this
point.
Life of Tire
The service life of a tire is dependent upon varying
factors including but not limited to:
•Driving style
•Tire pressure
•Distance driven
340 STARTING AND OPERATING

WARNING!
Tires and 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 an accident 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 balance of many
characteristics. They should be inspected regularly forwear and correct cold tire inflation pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed (refer to the paragraph on
“Tread Wear Indicators”). Refer to the “Tire and Loading
Information” placard for the size designation of your tire.
The service description and load identification will be
found on the original equipment tire. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your vehicle. We recommend
that you contact your original equipment or an autho-
rized tire dealer with any questions you may have on tire
specifications or capability.

ONBOARD DIAGNOSTIC SYSTEM (OBD II)
Vehicles equipped with California emissions controls
have a sophisticated onboard diagnostic system called
OBDII. This system monitors the performance of the
emissions, engine, and automatic transmission control
systems. When these systems are operating properly,
your vehicle will provide excellent performance and fuel
economy, as well as engine emissions well within current
government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light.” It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be driveable and not
need towing, see your dealer for service as soon as
possible.CAUTION!
Prolonged driving with the “Malfunction Indicator
Light” on could cause further damage to the emission
control system. It could also affect fuel economy and
driveability. The vehicle must be serviced before any
emissions tests can be performed.
If the “Malfunction Indicator Light” is flashing,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
REPLACEMENT PARTS
Use of genuine Moparparts for normal/scheduled
maintenance and repairs is highly recommended to in-
sure the designed performance. Damage or failures
caused by the use of non-Mopar parts for maintenance
and repairs will not be covered by the manufacturer’s
warranty.
410 MAINTAINING YOUR VEHICLE

NOTE:Care should be taken in disposing of used fluids
from your vehicle. Used fluids, indiscriminately dis-
carded, can present a problem to the environment. Con-
tact your local authorized dealer, service station, or
government agency for advice on recycling programs
and for where used fluids and filters can be properly
disposed of in your area.
NOTE:The fuel filter and water separator assembly is
located on the driver’s side of the engine.
Drain a small amount from the fuel/water separator
filter periodically or when the WATER IN FUEL indicator
lamp is on. Pull outward on the drain valve lever, located
on the side of the filter, and allow any accumulated water
to drain. Hold the drain valve open until all water and
contaminants have been removed. Close the drain release
valve, by returning it to the inward position, when clean
fuel is visible.NOTE:The Fuel / Water separator drain valve is
identified by its yellow handle and is located on the
inboard side of the fuel filter housing.
If more than a couple ounces of fuel has been drained,
follow the directions below for “Priming if the engine has
run out of fuel.”
WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.
Priming if the engine has run out of fuel
1. Add a substantial quantity of fuel to the tank 5 to 10
gallons (19L to 38L).

At Each Oil Change
•Change the engine oil filter.
•Inspect the exhaust system.
•Inspect the brake hoses.
•Inspect the U-Joints ( if equipped) and front suspen-
sion components.
•Check the automatic transmission fluid level.
•Check the manual transmission fluid level.
•Check the coolant level, hoses, and clamps.
•Lubricate outer tie rod ends (4X4) models only.
•Lubricate Front Drive Shaft Fitting ( 4X4).
Inspection and service should also be performed anytime
a malfunction is observed or suspected. Retain all re-
ceipts.
Oil Change Indicator System
Your vehicle is equipped with an engine oil change
indicator system. This system will alert you when it is
time to change your engine oil by displaying the words
“Oil Change Required” on your Electronic Vehicle Infor-
mation Center (EVIC). The engine oil change indicator
system is duty cycle based, which means the engine oil
change interval may fluctuate depending on your per-
sonal driving style. Driving styles such as frequent stop
and go type driving can increase the frequency of the
engine oil change. This is the result of more frequent
regeneration of the exhaust aftertreatment system, which
can decrease the life of the engine oil. Failure to change
the engine oil per the maintenance schedule can result in
internal engine damage.

For information on resetting the Oil Change Indicator
message, refer to “Oil Change Required – If Equipped,”
under “Personal Settings (Customer Programmable Fea-
tures),” in the “Electronic Vehicle Information Center
(EVIC)” Section of this manual.
Perform Service Indicator
Your vehicle will require emissions maintenance at a set
interval. To help remind you when this maintenance is
due, the Electronic Vehicle Information Center (EVIC)will display “Perform Service”. When the “Perform Ser-
vice” message is displayed on the EVIC it is necessary to
have the emissions maintenance performed. Emissions
maintenance includes replacing the Closed Crankcase
Ventilation (CCV) filter element, cleaning or replacement
of the EGR Cooler, and cleaning or replacement of the
EGR Valve. The procedure for clearing and resetting the
Perform Serviceindicator message is located in the
appropriate Service Information.
