²The lap portion should be low on the hips and as snug
as possible.
²Check belt fit periodically. A child's squirming or
slouching can move the belt out of position.
If the shoulder belt contacts the face or neck, move the
child closer to the center of the vehicle. Never allow a
child to put the shoulder belt under an arm or behind
their back.
Transporting Pets
Airbags deploying in the front seat could harm your pet.
An unrestrained pet will be thrown about and possibly
injured, or injure a passenger during panic braking or in
a collision. Pets should be restrained in the rear seat in
pet harnesses or pet carriers that are secured by seat belts.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine in
your new vehicle. Drive moderately during the first 300
miles (500 km). After the initial 60 mi (100 km), speeds up
to 50 or 55 mph (80 or 90 km/h) are desirable. While
cruising, brief full-throttle acceleration, within the limits
of local traffic laws, contributes to a good break-in.
Avoid wide-open throttle acceleration in low gear.
The engine oil installed in the engine at the factory is a
high-quality, energy-conserving type lubricant. Oil
changes should be consistent with the anticipated cli-
matic conditions under which vehicle operation will
occur. The recommended viscosity and quality grades are
discussed in Section 7 under Maintenance Procedures,
Engine Oil.
NON-DETERGENT OR STRAIGHT MINERAL OILS
MUST NEVER BE USED.
76 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Exhaust Gas
WARNING!
Exhaust gases contain carbon monoxide, a potentially
toxic gas that, by itself, is colorless and odorless. To
avoid inhaling these gases, the following precautions
should be observed:
²Do not run the engine in a closed garage or in confined
areas any longer than needed to move your vehicle in
or out of the area.
²If it is necessary to sit in a parked vehicle with the
engine running for more than a short period, adjust
your climate control system to force outside air into
the vehicle. Set the blower at high speed and the
controls in any position except OFF or MAX A/C.
²The best protection against carbon monoxide entry
into the vehicle body is a properly maintained engine
exhaust system.
Be aware of changes in the sound of the exhaust system,
exhaust fumes detected inside the vehicle, or damage to
the underside or rear of the vehicle. Have a competent
authorized mechanic inspect the complete exhaust sys-
tem 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 or adjust as required.
78 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

To reset a trip odometer, display the desired trip odom-
eter to be reset then push and hold the button until the
display resets (approximately two seconds).
Vehicle Warning Messages
When the appropriate conditions exist, messages such as
ªdoorº (indicates that a door(s) may be ajar), ªhoodº (if
the hood is open or ajar, on vehicles with remote start),
ªgASCAPº (which indicates that your gas cap is possibly
loose or damaged),9CHANgE OILº (indicates that the
engine oil should be change), ªLoWASHº (low washer
fluid), ªESPOFFº (indicates that ESP is turned off), and
ªnoFUSEº (indicates that the IOD fuse is removed from
the Integrated Power Module), will display in the odom-
eter.
NOTE:There is also an engine hour function. This
indicates the total number of hours the engine has been
running. To display the engine hours perform the follow-
ing: Place the ignition in RUN, but do not start theengine. With the odometer value displayed, hold the trip
button down for a period of six seconds. The odometer
will change to trip value first, then it will display the
engine hour value. The engine hours will be displayed
for a period of 30 seconds until the ignition is turned OFF
or the engine is started.
Change Oil Message
Your vehicle is equipped with an engine oil change
indicator system. The ªCHANgE OILº message will flash
in the instrument cluster odometer for approximately 12
seconds after a single chime has sounded to indicate the
next scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means the
engine oil change interval may fluctuate dependent upon
your personal driving style.
Unless reset, this message will continue to display each
time you turn the ignition switch to the ON/RUN
position. To turn off the message temporarily, press and
200 UNDERSTANDING YOUR INSTRUMENT PANEL

release the Trip Odometer button on the instrument
cluster. To reset the oil change indicator system (after
performing the scheduled maintenance) refer to the fol-
lowing procedure.
1. Turn the ignition switch to the ON position(Do not
start the engine).
2. Fully depress the accelerator pedal slowly three
times within 10 seconds.
3. Turn the ignition switch to the OFF/LOCK position.
NOTE:If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary repeat this procedure.
17. Front Fog Light Indicator Ð If Equipped
This light shows when the front fog lights are ON.18. Malfunction Indicator Light
This light is part of an onboard diagnostic system
which monitors the emissions and engine control
system. If the vehicle is ready for emissions
testing, the light will come on when the ignition is first
turned on and remain on, as a bulb check, until the
engine is started. If the vehicle is not ready for emissions
testing the light will come on when the ignition is first
turned on and remain on for 15 seconds, then blink for 5
seconds, and remain on until the vehicle is started. If the
bulb does not come on during starting, have the condi-
tion investigated promptly.
If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.
Although your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.

Change Engine Oil
Follow the Maintenance Schedule for recommended en-
gine oil change intervals.
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer only
recommends engine oils that are API-certified and meet
the requirements of DaimlerChrysler Material Standard
MS-6395.
American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacturer only recommends
API-Certified engine oils.
Engine Oil Viscosity (SAE Grade)
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy. The engine oil filler
cap also shows the recommended engine oil viscosity for
your engine. For information on engine oil filler cap
location, refer to the ªEngine Compartmentº illustration
in this section.
452 MAINTAINING YOUR VEHICLE

NOTE:Vehicles equipped with a 5.7L engine must use
SAE 5W-20 oil. Failure to do so may result in improper
operation of the Multi-Displacement System (MDS). Re-
fer to ªMulti-Displacement Systemº under ªStarting and
Operatingº in Section 5.
NOTE:For 2500/3500 trucks with a 5.7L engine oper-
ating under a gross combined weight rating of 14,000 lbs.
or greater, SAE 5W-30 engine oil is recommended for all
operating temperatures.
Lubricants, which do not have both the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber, should not be used.
Synthetic Engine Oils
You may use synthetic engine oils if the recommended oil
quality requirements are met, and the recommended
maintenance intervals for oil and filter changes are
followed.
Materials Added to Engine Oil
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental addi-
tives.
Disposing of Used Engine Oil and Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact your authorized dealer, service
station, or governmental agency for advice on how and
where used oil and oil filters can be safely discarded in
your area.

Engine Oil Filter
The engine oil filter should be replaced at every engine
oil change.
Engine Oil Filter Selection
The manufacturer's engines have a full-flow type oil
filter. Use a filter of this type for replacement. The quality
of replacement filters varies considerably. Only high-
quality filters should be used to assure most efficient
service. Mopar Engine Oil Filters are a high-quality oil
filter and are recommended.
Drive Belts Ð Check Condition and Tension
Belt tension is controlled by means of an automatic
tensioner. No belt tension adjustments are required.
However, belt and belt tensioner condition should be
inspected at the specified intervals and replaced if re-
quired. See your authorized dealer for service.At the mileage indicated in the maintenance schedule, all
belts and tensioner should be checked for condition.
Improper belt tension can cause belt slippage and failure.
Belts should be inspected for evidence of cuts, cracks,
glazing or frayed cords and replaced if there is indication
of damage which could result in belt failure. Low gen-
erator belt tension can cause battery failure.
Also check belt routing to make sure there is no interfer-
ence between the belts and other engine components.
Spark Plugs (Gas Engines)
Spark plugs must fire properly to assure engine perfor-
mance and emission control. New plugs should be in-
stalled at the specified mileage. The entire set should be
replaced if there is any malfunction due to a faulty spark
plug. Malfunctioning spark plugs can damage the cata-
lytic converter. For proper type of replacement spark
plugs, refer to the ªSpark Plugsº under ªFluids, Lubri-
cants and Genuine Partsº in Section 7.

Front Prop Shaft Lubrication Ð 2500/3500 (4X4)
Models
Lubricate the front driveshaft grease fitting at each oil
change listed in the appropriate Maintenance Schedule
for your vehicle. Use Moparttype MS-6560 (lithium-
based grease), or equivalent.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, doors, liftgate, tailgate, sliding doors and
hood hinges, should be lubricated periodically to assure
quiet, easy operation and to protect against rust and
wear. Prior to the application of any lubricant, the parts
concerned should be wiped clean to remove dust and
grit. After lubricating, excess oil and grease should be
removed. Particular attention should also be given to
hood latching components to ensure proper function.
When performing other underhood services, the hood
latch, release mechanism and safety catch should be
cleaned and lubricated. The external lock cylinders
should be lubricated twice a year, preferably in the Fall
and Spring. Apply a small amount of a high-quality
lubricant such as MopartLock Cylinder Lubricant di-
rectly into the lock cylinder.
