Air Bag Warning Light
The ORC monitors the readiness of the electronic
parts of the air bag system whenever the ignition
switch is in the START or ON/RUN position. If
the ignition switch is in the OFF position or in the
ACC position, the air bag system is not on and the air bags
will not inflate.
The ORC contains a backup power supply system that may
deploy the air bag system even if the battery loses power or
it becomes disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight seconds
for a self-check when the ignition switch is first in the
ON/RUN position. After the self-check, the Air Bag Warn-
ing Light will turn off. If the ORC detects a malfunction in
any part of the system, it turns on the Air Bag Warning
Light, either momentarily or continuously. A single chime
will sound to alert you if the light comes on again after
initial startup.
The ORC also includes diagnostics that will illuminate the
instrument panel Air Bag Warning Light if a malfunction is
detected that could affect the air bag system. The diagnos-
tics also record the nature of the malfunction. While the air bag system is designed to be maintenance free, if any of the
following occurs, have an authorized dealer service the air
bag system immediately.
•
The Air Bag Warning Light does not come on during the
four to eight seconds when the ignition switch is first in
the ON/RUN position.
• The Air Bag Warning Light remains on after the four to
eight-second interval.
• The Air Bag Warning Light comes on intermittently or
remains on while driving.
NOTE: If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. In this condition
the air bags may not be ready to inflate for your protection.
Have an authorized dealer service the air bag system
immediately.
WARNING!
Ignoring the Air Bag Warning Light in your instrument
panel could mean you won’t have the air bag system to
protect you in a collision. If the light does not come on
as a bulb check when the ignition is first turned on,

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 49

CAUTION!
•Failure to properly maintain your vehicle or perform
repairs and service when necessary could result in
more costly repairs, damage to other components or
negatively impact vehicle performance. Immediately
have potential malfunctions examined by an autho-
rized dealer or qualified repair center.
•
Your vehicle has been built with improved fluids that
protect the performance and durability of your vehicle
and also allow extended maintenance intervals. Do not
use chemical flushes in these components as the chemi-
cals can damage your engine, transmission, or air con-
ditioning. Such damage is not covered by the New
Vehicle Limited Warranty. If a flush is needed because
of component malfunction, use only the specified fluid
for the flushing procedure.
Engine Oil
Checking Oil Level — 3.6L Engine
To assure proper engine lubrication, the engine oil must be
maintained at the correct level. Check the oil level at
regular intervals, such as once a month. The best time to
check the engine oil level is about five minutes after a fully
warmed engine is shut off. Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Maintain the
oil level between the MIN and MAX markings on the
dipstick. Adding 1.0 quart (1.0 liter) of oil when the reading
is at the MIN mark will result in a MAX reading on these
engines.
CAUTION!
Overfilling or underfilling will cause oil aeration or
loss of oil pressure. This could damage your engine.
Checking Oil Level — 5.7L and 6.4L Engine
To assure proper engine lubrication, the engine oil must be
maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop. The best time to
check the engine oil level is about five minutes after a fully
warmed engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Maintain the
oil level in the “SAFE” range. Adding 1.0 quart (1.0 liter) of
oil when the reading is at the bottom of the “SAFE” range

MAINTAINING YOUR VEHICLE 447

NOTE:Vehicles equipped with a 5.7L engine must use SAE
5W-20 oil. Failure to do so may result in improper opera-
tion of the Fuel Saver Technology. Refer to “Fuel Saver
Technology – If Equipped” in “Starting And Operating” for
further information.
Lubricants which do not have both the engine oil certifi-
cation mark and the correct SAE viscosity grade number
should not be used.
Engine Oil Viscosity — 6.4L Engine
Use Pennzoil Ultra 0W-40 engine or equivalent Mopar oil
meeting the FCA Material Standard MS-12633 for use in all
operating temperatures.
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 “Engine Compart-
ment” in “Maintaining Your Vehicle” for further informa-
tion.
Synthetic Engine Oils
You may use synthetic engine oils provided the recom-
mended oil quality requirements are met, and the recom-
mended maintenance intervals for oil and filter changes are
followed. Synthetic engine oils which do not have both the engine oil
certification mark and the correct SAE viscosity grade
number should not be used.
Materials Added To Engine Oil
The manufacturer strongly recommends against the addi-
tion 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 additives.
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 sta-
tion 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 with a new filter at
every engine oil change.
Engine Oil Filter Selection
This 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
450 MAINTAINING YOUR VEHICLE

filters should be used to assure most efficient service.
Mopar engine oil filters are high quality oil filters and are
recommended.
Engine Air Cleaner Filter
Refer to the “Maintenance Schedule” for the proper main-
tenance intervals.
WARNING!
The air induction system (air cleaner, hoses, etc.) can
provide a measure of protection in the case of engine
backfire. Do not remove the air induction system (air
cleaner, hoses, etc.) unless such removal is necessary
for repair or maintenance. Make sure that no one is
near the engine compartment before starting the ve-
hicle with the air induction system (air cleaner, hoses,
etc.) removed. Failure to do so can result in serious
personal injury.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner filters varies
considerably. Only high quality filters should be used to
assure most efficient service. Mopar engine air cleaner
filters are a high quality filter and are recommended.
Maintenance-Free Battery

Fluid Changes
Refer to the “Maintenance Schedule” for the proper main-
tenance intervals.
Rear Axle
For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons the
exterior surfaces of the axle assembly should be inspected.
If gear oil leakage is suspected inspect the fluid level. Refer
to “Fluids, Lubricants, And Genuine Parts” in “Maintain-
ing Your Vehicle” for further information.
Fluid Level Check
Check the fluid level by removing the fill plug on the axle.
The fluid level should be at the bottom of the fill hole. Add
fluid, if necessary, to maintain the proper level. Refer to
“Fluids, Lubricants, And Genuine Parts” in “Maintaining
Your Vehicle” for further information.
Change Axle Fluid
Refer to the “Maintenance Schedule” for the proper main-
tenance intervals.
Appearance Care And Protection From Corrosion
Protection Of Body And Paint From Corrosion
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice, and chemicals that are sprayed
on trees and road surfaces during other seasons, are highly
corrosive to the metal in your vehicle. Outside parking,
which exposes your vehicle to airborne contaminants, road
surfaces on which the vehicle is operated, extreme hot or
cold weather and other extreme conditions will have an
adverse effect on paint, metal trim, and underbody protec-
tion.
The following maintenance recommendations will enable
you to obtain maximum benefit from the corrosion resis-
tance built into your vehicle.
What Causes Corrosion?
Corrosion is the result of deterioration or removal of paint
and protective coatings from your vehicle.
The most common causes are:
•Road salt, dirt and moisture accumulation.
• Stone and gravel impact.
466 MAINTAINING YOUR VEHICLE

MAINTENANCE SCHEDULE — 5.7L
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
frequent short-trips, trailer tow, extremely hot or cold
ambient temperatures, and E85 fuel usage will influence
when the “Change Oil” or “Oil Change Required” message
is displayed. Severe Operating Conditions can cause the
change oil message to illuminate as early as 3,500 miles
(5,600 km) since last reset. Have your vehicle serviced as
soon as possible, within the next 500 miles (805 km).
The message “Oil Change Required” will be displayed in
the instrument cluster and a single chime will sound,
indicating that an oil change is necessary.
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other than
your authorized dealer, the message can be reset byreferring to the steps described under “Instrument Cluster
Display” in “Understanding Your Instrument Panel” for
further information.
NOTE:
Under no circumstances should oil change intervals
exceed 10,000 miles (16,000 km), twelve months or 350 hours of
engine run time, whichever comes first. The 350 hours of engine
run or idle time is generally only a concern for fleet customers.
Severe Duty All Models
Change Engine Oil at 4,000 miles (6,500 km) if the vehicle
is operated in a dusty and off-road environment or is
operated predominately at idle or only very low engine
RPM’s. This type of vehicle use is considered Severe Duty.
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 your next scheduled service.
• Check the fluid levels of the coolant reservoir, brake
master cylinder, and power steering and fill as needed.
• Check function of all interior and exterior lights.
