3. Remove and replace the battery. When re-
placing the battery, match the + sign on the
battery to the + sign on the inside of the battery
clip, located on the back cover. Avoid touching
the new battery with your fingers. Skin oils may
cause battery deterioration. If you touch a
battery, clean it with rubbing alcohol.
4. To assemble the RKE transmitter case, snap
the two halves together.
General InformationThe RKE transmitter and receivers operate on a
carrier frequency of 433.92 MHz as required by
EEC regulations. These devices must be certi-
fied to conform to specific regulations in each
individual country. Two sets of regulations are
involved: ETS (European Telecommunication
Standard) 300–220, which most countries use,
and German BZT federal regulation 225Z125,
which is based on ETC 300–220 but has addi-
tional unique requirements. Other defined re-
quirements are noted in ANNEX VI of COMMIS-
SION DIRECTIVE 95/56/EC. Operation is
subject to the following two conditions:
•This device may not cause harmful interfer-
ence. •
This device must accept any interference
received, including interference that may
cause undesired operation.
If your RKE transmitter fails to operate from a
normal distance, check for these two condi-
tions:
1. Weak battery in RKE transmitter. The ex-
pected life of the battery is a minimum of three
years.
2. Closeness to a radio transmitter such as a
radio station tower, airport transmitter, and
some mobile or CB radios.
DOOR LOCKSThe power door locks can be manually locked
from inside the vehicle by using the door lock
knob. To lock each door, push the door lock
knob on each door trim panel downward. To
unlock the front doors, pull the inside door
handle to the first detent. To unlock the rear
doors, pull the door lock knob on the door trim
panel upward. If the lock knob is down when
the door is closed, the door will lock. Therefore,
make sure the key is not inside the vehicle
before closing the door.
WARNING!
• For personal security and safety in the
event of an accident, lock the vehicle doors
when you drive, as well as when you park
and leave the vehicle.
• When leaving the vehicle, always remove
the key fob from the ignition and lock your
vehicle.
• Never leave children alone in a vehicle, or
with access to an unlocked vehicle.

WARNING!
•Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
• It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a
collision, people riding in these areas are
more likely to be seriously injured or killed.
• Do not allow people to ride in any area of
your vehicle that is not equipped with seats
and seat belts.
• Be sure everyone in your vehicle is in a
seat and using a seat belt properly.
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you uncon-
scious and can eventually poison you. To
avoid breathing (CO), follow these safety tips: Do 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.
If it is necessary to sit in a parked vehicle with
the engine running, adjust your heating or
cooling controls to force outside air into the
vehicle. Set the blower at high speed.
If you are required to drive with the trunk/liftgate
open, make sure that all windows are closed
and the climate control BLOWER switch is set
at high speed. DO NOT use the recirculation
mode.
The best protection against carbon monoxide
entry into the vehicle body is a properly main-
tained engine exhaust system.
Whenever a change is noticed in the sound of
the exhaust system, when exhaust fumes can
be detected inside the vehicle, or when the
underside or rear of the vehicle is damaged,
have a competent mechanic inspect the com-
plete exhaust 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.
Safety Checks You Should Make
Inside The Vehicle
Seat Belts
Inspect the belt system periodically, checking
for cuts, frays, and loose parts. Damaged parts
must be replaced immediately. Do not disas-
semble or modify the system.
Front seat belt assemblies must be replaced
after a collision. Rear seat belt assemblies must
be replaced after a collision if they have been
damaged (i.e., bent retractor, torn webbing,
etc.). If there is any question regarding belt or
retractor condition, replace the belt.
Air Bag Warning Light
The light should come on and remain on for four
to eight seconds as a bulb check when the
ignition switch is first turned ON. If the light is
not lit during starting, see your authorized
dealer. If the light stays on, flickers, or comes
on while driving, have the system checked by
an authorized dealer.

Periodic Safety Checks You Should
Make Outside The Vehicle
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones, nails,
glass, or other objects lodged in the tread or
sidewall. Inspect the tread for cuts and cracks.
Inspect sidewalls for cuts, cracks and bulges.
Check the wheel nuts for tightness. Check the
tires (including spare) for proper cold inflation
pressure.Lights
Have someone observe the operation of exte-
rior lights while you work the controls. Check
turn signal and high beam indicator lights on
the instrument panel.
Door Latches
Check for positive closing, latching, and lock-
ing.
Fluid Leaks
Check area under vehicle after overnight park-
ing for fuel, engine coolant, oil, or other fluid
leaks. Also, if gasoline fumes are detected or if
fuel, power steering fluid, or brake fluid leaks
are suspected, the cause should be located
and corrected immediately.

NOTE:
Your vehicle is capable of water fording in
up to 20 inches (51 cm) of water, while
crossing small rivers or streams. To main-
tain optimal performance of your vehicle’s
heating and ventilation system it is recom-
mended to switch the system into recircula-
tion mode during water fording.
CAUTION!
When driving through water, do not exceed
5 mph (8 km/h). Always check water depth
before entering, as a precaution, and check all
fluids afterward. Driving through water may
cause damage that may not be covered by the
New Vehicle Limited Warranty.
Driving through water more than a few inches/
centimeters deep will require extra caution to
ensure safety and prevent damage to your
vehicle. If you must drive through water, try to
determine the depth and the bottom condition
(and location of any obstacles) prior to enter-
ing. Proceed with caution and maintain a steady controlled speed less than 5 mph
(8 km/h) in deep water to minimize wave ef-
fects.
Flowing Water
If the water is swift flowing and rising (as in
storm run-off), avoid crossing until the water
level recedes and/or the flow rate is reduced. If
you must cross flowing water avoid depths in
excess of 9 inches (23 cm). The flowing water
can erode the streambed, causing your vehicle
to sink into deeper water. Determine exit
point(s) that are downstream of your entry point
to allow for drifting.
Standing Water
Avoid driving in standing water deeper than
20 inches (51 cm), and reduce speed appro-
priately to minimize wave effects. Maximum
speed in 20 inches (51 cm) of water is less than
5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your
vehicle fluids and lubricants (engine oil, trans-
mission oil, axle, transfer case) to assure the
fluids have not been contaminated. Contami-
nated fluid (milky, foamy in appearance) shouldbe flushed/changed as soon as possible to
prevent component damage.
Driving In Snow, Mud And SandIn heavy snow, when pulling a load, or for
additional control at slower speeds, shift the
transmission to a low gear and shift the transfer
case to 4WD LOW if necessary. Refer to “Four-
Wheel Drive Operation” in “Starting and Oper-
ating” for further information. Do not shift to a
lower gear than necessary to maintain forward
motion. Over-revving the engine can spin the
wheels and traction will be lost.
Avoid abrupt downshifts on icy or slippery
roads, because engine braking may cause
skidding and loss of control.
Hill Climbing
NOTE:
Before attempting to climb a hill, determine
the conditions at the crest and/or on the
other side.
Before climbing a steep hill,
shift the trans-
mission to a lower gear and shift the transfer
case to 4WD LOW. Use first gear and 4WD
LOW for very steep hills.

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.

CAUTION!
•It is essential when replacing the cables on
the battery that the positive cable is at-
tached to the positive post, and the nega-
tive cable is attached to the negative post.
Battery posts are marked (+) positive and
(-) negative and identified on the battery
case.
• If a “fast charger” is used while battery is in
the vehicle, disconnect both vehicle battery
cables before connecting the charger to the
battery. Do not use a “fast charger” to
provide starting voltage.
Air Conditioner MaintenanceFor best possible performance, your air condi-
tioner should be checked and serviced by an
authorized dealer at the start of each warm
season. This service should include cleaning of
the condenser fins and a performance test.
Drive belt condition should also be checked at
this time.
CAUTION!
Do not use chemical flushes in your air con-
ditioning system as the chemicals can dam-
age your air conditioning components. Such
damage is not covered by the New Vehicle
Limited Warranty.
WARNING!
•Use only refrigerants and compressor lubri-
cants approved by the manufacturer for
your air conditioning system. Some unap-
proved refrigerants are flammable and can
explode, injuring you. Other unapproved
refrigerants or lubricants can cause the
system to fail, requiring costly repairs.
• The air conditioning system contains refrig-
erant under high pressure. To avoid risk of
personal injury or damage to the system,
adding refrigerant or any repair requiring
lines to be disconnected should be done by
an experienced repairman. NOTE:
Use only manufacturer approved A/C Sys-
tem Sealers, Stop Leak Products, Seal Con-
ditioners, Compressor Oil, and Refrigerants.
Refrigerant Recovery And Recycling
R-134a Air Conditioning Refrigerant is a hydro-
fluorocarbon (HFC) that is endorsed by the
Environmental Protection Agency (EPA) and is
an ozone-saving product. However, the manu-
facturer recommends that air conditioning ser-
vice be performed by authorized dealers or
other service facilities using recovery and recy-
cling equipment.
Body LubricationLocks and all body pivot points, including such
items as seat tracks, door hinge pivot points
and rollers, liftgate, tailgate, sliding doors and
hood hinges, should be lubricated periodically
with a lithium based grease, such as MOPAR
Spray White Lube or equivalent 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
