dealer for service. It is likely the vehicle has lost
power steering assistance. Refer to “Electronic
Vehicle Information (EVIC)” in “Understanding
Your Instrument Panel” for further information.
If the “POWER STEERING SYSTEM OVER
TEMP” message and an icon are displayed on
the EVIC screen, it indicates that extreme steer-
ing maneuvers may have occurred, which
caused an over temperature condition in the
power steering system. You will lose power
steering assistance momentarily until the over
temperature condition no longer exists. Once
driving conditions are safe, then pull over and
let vehicle idle for a few moments until the light
turns off. Refer to “Electronic Vehicle Informa-
tion (EVIC)” in “Understanding Your Instrument
Panel” for further information.
NOTE:
•Even if power steering assistance is no
longer operational, it is still possible to
steer the vehicle. Under these conditions
there will be a substantial increase in
steering effort, especially at very low ve-
hicle speeds and during parking maneu-
vers. •
If the condition persists, see your autho-
rized dealer for service.
5.7L EngineThe standard power steering system will give
you good vehicle response and increased ease
of maneuverability in tight spaces. The system
will provide mechanical steering capability if
power assist is lost.
If for some reason the power assist is inter-
rupted, it will still be possible to steer your
vehicle. Under these conditions, you will ob-
serve a substantial increase in steering effort,
especially at very low vehicle speeds and
during parking maneuvers.
NOTE:
• Increased noise levels at the end of the
steering wheel travel are considered nor-
mal and do not indicate that there is a
problem with the power steering system.
• Upon initial start-up in cold weather, the
power steering pump may make noise for
a short amount of time. This is due to the
cold, thick fluid in the steering system. This noise should be considered normal,
and it does not in any way damage the
steering system.WARNING!
Continued operation with reduced power
steering assist could pose a safety risk to
yourself and others. Service should be ob-
tained as soon as possible.
CAUTION!
Prolonged operation of the steering system at
the end of the steering wheel travel will in-
crease the steering fluid temperature and it
should be avoided when possible. Damage to
the power steering pump may occur.
Power Steering Fluid CheckChecking the power steering fluid level at a
defined service interval is not required. The
fluid should only be checked if a leak is sus-
pected, abnormal noises are apparent, and/or
the system is not functioning as anticipated.
Coordinate inspection efforts through an autho-
rized dealer.
221

CAUTION!
Do not use chemical flushes in your power
steering system as the chemicals can dam-
age your power steering components. Such
damage is not covered by the New Vehicle
Limited Warranty.
WARNING!
Fluid level should be checked on a level
surface and with the engine off to prevent
injury from moving parts and to ensure accu-
rate fluid level reading. Do not overfill. Use
only manufacturer’s recommended power
steering fluid.
If necessary, add fluid to restore to the proper
indicated level. With a clean cloth, wipe any
spilled fluid from all surfaces. Refer to “Fluids,
Lubricants, and Genuine Parts” in “Maintaining
Your Vehicle” for further information.
MULTI-DISPLACEMENT SYSTEM
(MDS) (IF EQUIPPED) — 5.7L
ENGINE ONLY
This feature offers improved fuel economy by
shutting off four of the engine’s eight cylinders
during light load and cruise conditions. The
system is automatic with no driver inputs or
additional driving skills required.
NOTE:
The MDS system may take some time to
return to full functionality after a battery
disconnect.
PARKING BRAKEBefore leaving the vehicle, make sure that the
parking brake is fully applied and place the
shift lever in the PARK position.
The foot operated parking brake is located
below the lower left corner of the instrument
panel. To apply the park brake, firmly push the
park brake pedal fully. To release the parking
brake, press the park brake pedal a second
time and let your foot up as you feel the brake
disengage. When the parking brake is applied with the
ignition switch in the ON position, the “Brake
Warning Light” in the instrument cluster will
illuminate.
NOTE:
•
When the parking brake is applied and the
transmission is placed in gear, the “Brake
Warning Light” will flash. If vehicle speed
is detected, a chime will sound to alert the
driver. Fully release the parking brake
before attempting to move the vehicle.

sive shifting and heat buildup. This action
will also provide better engine braking.
The transmission fluid and filter should be
changed if you REGULARLY tow a trailer for
more than 45 minutes of continuous operation.
Refer to “Maintenance Schedule” for the proper
maintenance intervals.
NOTE:
Check the transmission fluid level before
towing (5.7L engine).
To help maintain a comfortable operating
temperature for your transmission, it is rec-
ommended that when towing a maximum
loaded trailer up steep grades with switch
backs, you should use the ERS function on
the transmission shifter to lock your vehicle
into first gear (5.7L Models Only).
Electronic Speed Control – If Equipped
Do not use in hilly terrain or with heavy loads.
When using the speed control, if you expe-rience speed drops greater than 10 mph
(16 km/h), disengage until you can get back
to cruising speed. Use speed control in flat terrain and with light
loads to maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission
overheating, take the following actions:
City Driving
When stopped for short periods of time, shift
the transmission into NEUTRAL and increase
engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
Trailer Hitch Attaching Points
Your vehicle will require extra equipment to tow
a trailer safely and efficiently. The trailer tow
hitch must be attached to your vehicle using
the provided attaching points on the vehicle’s
frame. Refer to the following chart to determine
the accurate attaching points. Other equip-
ment, such as trailer sway controls and braking
equipment, trailer equalizing (leveling) equip-
ment and low profile mirrors, may also be
required or strongly recommended.

The Keyless Enter-N-Go button (if equipped)
may now be reinstalled if desired. Refer to “Start- ing Procedures/Keyless Enter-N-Go” in “Starting
and Operating” for further information.
NOTE:
•
Steps 1 through 7 are requirements that
must be met prior to pressing the NEU-
TRAL (N) button, and must continue to be
met until the shift has been completed. If
any of these requirements are not met
prior to pressing the NEUTRAL (N) button
or are no longer met during the shift, the
NEUTRAL (N) indicator light will flash
continuously until all requirements are
met or until the NEUTRAL (N) button is
released. •
The ignition switch must be in the ON/
RUN position for a shift to take place and
for the position indicator lights to be op-
erable. If the ignition switch is not in the
ON/RUN position, the shift will not take
place and no position indicator lights will
be on or flashing.
• A flashing NEUTRAL (N) position indica-
tor light indicates that shift requirements
have not been met.
255

CAUTION!
•Failure to properly maintain your vehicle or
perform repairs and service when neces-
sary could result in more costly repairs,
damage to other components or negatively
impact vehicle performance. Immediately
have potential malfunctions examined by
an authorized dealership 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 chemicals can damage your engine,
transmission, power steering or air condi-
tioning. Such damage is not covered by the
New Vehicle Limited Warranty. If a flush is
needed because of component malfunc-
tion, use only the specified fluid for the
flushing procedure.Engine Oil – Gasoline Engines
Checking Oil Level
To assure proper lubrication of your vehicle’s
engine, the engine oil must be maintained at
the correct level. The best time to check the
engine oil level is about five minutes after a fully
warmed up engine is shut off or before starting
the engine after it has sat overnight.
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 level
range. Adding 1 U.S. Quart (0.95L) of oil when
the level is at the bottom of the SAFE range will
result in the level being at the top of the SAFE
range.
CAUTION!
Overfilling or underfilling the crankcase will
cause aeration or loss of oil pressure. This
could damage your engine.
Change Engine Oil
Refer to the “Maintenance Schedule” for the
proper maintenance intervals. NOTE:
Under no circumstances should oil change
intervals exceed 7,500 miles (12 000 km) or
six months whichever comes first.
Engine Oil Selection – Non ACEA
Categories
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 require-
ments of Chrysler Material Standard MS-6395.
American Petroleum Institute (API) Engine
Oil Identification Symbol
This symbol means
that the oil has
been certified by
the American Pe-
troleum Institute
(API). The manu-
facturer only rec-
ommends API Cer-
tified engine oils.
274

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 lubri-
cated twice a year, preferably in the Fall and
Spring. Apply a small amount of a high quality
lubricant, such as MOPARLock Cylinder Lu-
bricant or equivalent directly into the lock cyl-
inder.
Windshield Wiper BladesClean the rubber edges of the wiper blades
and the windshield periodically with a sponge
or soft cloth and a mild nonabrasive cleaner to
remove accumulations of salt or road film.
Operation of the wipers on dry glass for long
periods may cause deterioration of the wiper
blades. Always use washer fluid when using
the wipers to remove salt or dirt from a dry
windshield.
Avoid using the wiper blades to wipe frost or
ice from the windshield. Keep the blade rubber
out of contact with petroleum products such as
engine oil, gasoline, etc. NOTE:
Life expectancy of wiper blades varies de-
pending on geographical area and fre-
quency of use. Poor performance of blades
may be present with chattering, marks, wa-
ter lines or wet spots. If any of these condi-
tions are present, clean the wiper blades or
replace as necessary.
Adding Washer FluidThe fluid reservoir for the windshield washers
and the rear window washer is shared. The fluid
reservoir is located in the engine compartment,
be sure to check the fluid level at regular
intervals. Fill the reservoir with windshield
washer solvent only (not radiator antifreeze).
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 solution or mixture that meets
or exceeds the temperature range of your cli-
mate. This rating 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.
Exhaust SystemThe best protection against carbon monoxide
entry into the vehicle body is a properly main-
tained engine exhaust system.
If you notice a change in the sound of the
exhaust system; or if the exhaust fumes can be
detected inside the vehicle; or when the under-
side or rear of the vehicle is damaged; have an
authorized technician inspect the complete ex-
haust system and adjacent body areas for
broken, damaged, deteriorated, or misposi-
tioned 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 as
required.
278

•Do not idle the engine with any spark plug
wires disconnected or removed, such as
when diagnostic testing, or for prolonged
periods during very rough idle or malfunc-
tioning operating conditions.
Cooling System
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam coming
from under the hood, do not open the hood
until the radiator has had time to cool. Never
try to open a cooling system pressure cap
when the radiator or coolant bottle is hot.
Engine Coolant Checks
Check the engine coolant (antifreeze) protec-
tion every 12 months (before the onset of
freezing weather, where applicable). If the en-
gine coolant (antifreeze) is dirty or rusty in
appearance, the system should be drained,
flushed and refilled with fresh engine coolant
(antifreeze). Check the front of the A/C con-
denser for any accumulation of bugs, leaves, etc. If dirty, clean by gently spraying water from
a garden hose vertically down the face of the
condenser.
Check the engine cooling system hoses for
brittle rubber, cracking, tears, cuts, and tight-
ness of the connection at the coolant recovery
bottle and radiator. Inspect the entire system
for leaks.
With the engine at normal operating tempera-
ture (but not running), check the cooling sys-
tem pressure cap for proper vacuum sealing by
draining a small amount of engine coolant
(antifreeze) from the radiator drain cock. If the
cap is sealing properly, the engine coolant
(antifreeze) will begin to drain from the coolant
recovery bottle. DO NOT REMOVE THE COOL-
ANT PRESSURE CAP WHEN THE COOLING
SYSTEM IS HOT.
Cooling System – Drain, Flush, and Refill
If the engine coolant (antifreeze) is dirty and
contains a considerable amount of sediment,
clean and flush with reliable cooling system
cleaner. Follow with a thorough rinsing to re-
move all deposits and chemicals. Properly dis-
pose of the old engine coolant (antifreeze).
Refer to the “Maintenance Schedule” for the
proper maintenance intervals.
Selection Of Coolant
Use only the manufacturer’s recommended en-
gine coolant (antifreeze). Refer to “Fluids, Lu-
bricants, and Genuine Parts” in “Maintaining
Your Vehicle” for further information.CAUTION!
•
Mixing of engine coolant (antifreeze), other
than the specified HOAT engine coolant
(antifreeze), may result in engine damage
and may decrease corrosion protection. If a
non-HOAT engine coolant (antifreeze) is
introduced into the cooling system in an
emergency, it should be replaced with the
specified engine coolant (antifreeze) as
soon as possible.
(Continued)
280

WARNING!(Continued)
• Do not use a pressure cap other than the
one specified for your vehicle. Personal
injury or engine damage may result.
Disposal of Used Engine Coolant
Used ethylene glycol-based engine coolant
(antifreeze) is a regulated substance requiring
proper disposal. Check with your local authori-
ties to determine the disposal rules for your
community. To prevent ingestion by animals
and children, do not store ethylene glycol-
based engine coolant (antifreeze) in open con-
tainers or allow it to remain in puddles on the
ground. If ingested by a child or pet, seek
emergency assistance immediately. Clean up
any ground spills immediately.
Coolant Level
The coolant bottle provides a quick visual
method for determining that the engine coolant
(antifreeze) level is adequate. With the engine
idling, and warm to normal operating tempera-
ture, the level of the engine coolant (antifreeze)
in the bottle should be between the ranges
indicated on the bottle. The radiator normally remains completely full,
so there is no need to remove the radiator cap,
unless checking for engine coolant (antifreeze)
freeze point or replacing engine coolant (anti-
freeze). Advise your service attendant of this.
As long as the engine operating temperature is
satisfactory, the coolant bottle need only be
checked once a month.
When additional engine coolant (antifreeze) is
needed to maintain the proper level, it should
be added to the coolant bottle. Do not overfill.
Points To Remember
NOTE:
When the vehicle is stopped after a few
miles (kilometers) of operation, you may
observe vapor coming from the front of the
engine compartment. This is normally a re-
sult of moisture from rain, snow, or high
humidity accumulating on the radiator and
being vaporized when the thermostat opens,
allowing hot engine coolant (antifreeze) to
enter the radiator.
If an examination of your engine compartment
shows no evidence of radiator or hose leaks,
the vehicle may be safely driven. The vapor will
soon dissipate.
•
Do not overfill the coolant recovery bottle.
• Check engine coolant (antifreeze) freeze
point in the radiator and in the coolant recov-
ery bottle. If engine coolant (antifreeze)
needs to be added, contents of coolant
recovery bottle must also be protected
against freezing.
• If frequent engine coolant (antifreeze) addi-
tions are required, or if the level in the
coolant recovery bottle does not drop when
the engine cools, the cooling system should
be pressure tested for leaks.
• Maintain engine coolant (antifreeze) concen-
tration at 50% HOAT engine coolant (anti-
freeze) (minimum) and distilled water for
proper corrosion protection of your engine,
which contains aluminum components.
• Make sure that the radiator and coolant
recovery bottle hoses are not kinked or ob-
structed.
282

WARNING!(Continued)
• Overfilling the brake fluid reservoir can
result in spilling brake fluid on hot engine
parts, causing the brake fluid to catch fire.
Brake fluid can also damage painted and
vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to con-
taminate the brake fluid. Brake seal com-
ponents could be damaged, causing partial
or complete brake failure. This could result
in an accident.
Front/Rear Axle FluidFor 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 “Maintaining Your Vehicle” for further
information. Front Axle Fluid Level Check
The front axle oil level needs to be between
1/8 in (3 mm) below the bottom of the fill hole
and the bottom of the fill hole.
The front axle fill and drain plugs should be
tightened to 22 to 29 ft lbs (30 to 40 N·m).
CAUTION!
Do not over tighten the plugs as it could
damage them and cause them to leak.
Rear Axle Fluid Level Check
The rear axle oil level needs to be between
1/8 in (3 mm) below the bottom of the fill hole
and the bottom of the fill hole.
The rear axle fill and drain plugs should be
tightened to 22 to 29 ft lbs (30 to 40 N·m) on
axles with aluminum housings. The rear axle fill
and drain plugs should be tightened to 22 to
52 ft lbs (30 to 70 N·m) on axles with cast iron
housings.
CAUTION!
Do not over tighten the plugs as it could
damage then and cause them to leak.
Selection of Lubricant
Use only the manufacturer’s recommended
fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information.
Transfer Case
Fluid Level Check
Inspect the transfer case for fluid leaks. If a fluid
leak is found, the transfer case fluid level can
be checked by removing the filler plug located
on the back side of the transfer case. The fluid
level should be at the bottom edge of the filler
plug hole when the vehicle is in a level position.
Adding Fluid
Add fluid at the filler hole, until it runs out of the
hole, when the vehicle is in a level position.
Drain
First remove fill plug, then remove drain plug.
Recommended tightening torque for drain and
fill plugs is 15 to 25 ft lbs (20 to 34 N·m).
284

CAUTION!
When installing plugs, do not overtighten. You
could damage them and cause them to leak.
Selection of Lubricant
Use only the manufacturer’s recommended
fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information.
Automatic Transmission
Selection of Lubricant
It is important that the proper lubricant is used
in the transmission to assure optimum transmis-
sion performance. Use only the manufacturer’s
recommended transmission fluid. Refer to “Flu-
ids, Lubricants, and Genuine Parts” in “Main-
taining Your Vehicle” for further information. It is
important that the transmission fluid be main-
tained at the prescribed level using the recom-
mended fluid.
CAUTION!
Using a transmission fluid other than the
manufacturer’s recommended fluid may
cause deterioration in transmission shift qual-
ity and/or torque converter shudder. Using a
transmission fluid other than the manufactur-
er’s recommended fluid will result in more
frequent fluid and filter changes. Refer to
“Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further informa-
tion.
Special Additives
Automatic Transmission Fluid (ATF) is an engi-
neered product and its performance may be
impaired by supplemental additives. Therefore,
do not add any fluid additives to the transmis-
sion. The only exception to this policy is the use
of special dyes to aid in detecting fluid leaks. In
addition, avoid using transmission sealers as
they may adversely affect seals.CAUTION!
Do not use chemical flushes in your transmis-
sion as the chemicals can damage your trans-
mission components. Such damage is not
covered by the New Vehicle Limited Warranty.
Fluid Level Check – 3.6L and 3.0L Diesel
Engine
Regular fluid level checks are not required. For
this reason, the dipstick is omitted.
If you notice fluid loss or transmission malfunc-
tion, have your authorized dealer check the
transmission fluid level.
