WARNING!
An incorrectly anchored tether strap could lead to
increased head motion and possible injury to the
child. Use only the anchor positions directly behind
the child seat to secure a child restraint top tether
strap.
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 vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (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.
Wide-open throttle acceleration in low gear can be detri-
mental and should be avoided.
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil
changes should be consistent with anticipated climate
conditions under which vehicle operations will occur.
The recommended viscosity and quality grades are
shown in “Engine Oil”, under “Maintenance Procedures”
in section 7 of this manual. NON-DETERGENT OR
STRAIGHT MINERAL OILS MUST NEVER BE USED.
80 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

simultaneously. If this occurs, the Electronic Speed Con-
trol System can be reactivated by pushing the Electronic
Speed Control ON/OFF button and resetting the desired
vehicle set speed.
To Activate
Push and release the ON/OFF button located
on the end of the Electronic Speed Control
lever. The Cruise indicator lamp in the instru-
ment cluster will illuminate. To turn the system
off, push and release the ON/OFF button a second time.
The Cruise indicator lamp will turn off. Be sure to turn
the Electronic Speed Control system off when not in use.
NOTE: The Electronic Speed Control system will auto-
matically turn off when the engine is turned off.

WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer-
ship for service if your vehicle overheats. If you
decide to look under the hood yourself, see Section 7
of this manual. Follow the warnings under the Cool-
ing System Pressure Cap paragraph.
24. Transmission Temperature Indicator — If Equipped This light indicates that the transmission fluid
temperature is running hot. This may occur
with severe usage, such as trailer towing. If this
light turns on, safely pull over and stop the
vehicle. Then, shift the transmission into NEUTRAL and
run the engine at idle or faster until the light turns off. 25. Trip Odometer Button
Changing the Display
Press and release this button once to change the display
from odometer to “Trip A.” Press and release it again to
change the display from “Trip A” to “Trip B.” On vehicles
equipped with a Base Cluster, press and release it once
again to display the outside temperature. On vehicles
equipped with a Mid Line Cluster, press and release it
once again to display the outside temperature and com-
pass heading in the screen below the speedometer. Refer
to “Vacuum Fluorescent Display” for details.
Resetting the Trip Odometer
Display the trip mileage that you want to reset, “Trip A”
or “Trip B.” Then push and hold the button (approxi-
mately two seconds) until the display resets to 0. The
odometer must be in Trip Mode to reset the trip odom-
eter.

If Engine Fails to Start

WARNING! (Continued)
•It is dangerous to move the shift lever out of PARK
or NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly on the brake
pedal, the vehicle could accelerate quickly forward
or in reverse. You could lose control of the vehicle
and hit someone or something. Only shift into
gear when the engine is idling normally and when
your right foot is firmly on the brake pedal.
REVERSE
This range is for moving the vehicle rearward. Use this
range only after the vehicle has come to a complete stop.
NEUTRAL
This range is used when the vehicle is standing for
prolonged periods with the engine running. The engine
may be started in this range. Set the parking brake if you
must leave the vehicle. NOTE:
Towing the vehicle, coasting, or driving for any
other reason with shift lever in NEUTRAL can result in
severe transmission damage. Refer to “Recreational Tow-
ing” in Section 5 and “Towing a Disabled Vehicle” in
Section 6 of this manual.
DRIVE
This range is used for most city and highway driving.
2 (Second)
This range is used for moderate grades and to assist
braking on dry pavement or in mud and snow. Begins at
a stop in low gear with automatic upshift to 2nd gear.
Will not shift to 3rd gear.
1 (First)
This range is used for hard pulling at low speeds in mud,
sand, snow, or on steep grades. Begins and stays in low
gear with no upshift. Provides engine compression brak-
ing at low speeds.
298 STARTING AND OPERATING

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 transmission to a
lower gear and shift the transfer case to 4WD LOW. Use
first gear and 4WD LOW for very steep hills.
If you stall or begin to lose headway while climbing a
steep hill, allow your vehicle to come to a stop and
immediately apply the brakes. Restart the engine and
shift to REVERSE. Back slowly down the hill allowing the
compression braking of the engine to help regulate your
speed. If the brakes are required to control vehicle speed,
apply them lightly and avoid locking or skidding the
tires.

Cuts and punctures in radial tires are repairable only in
the tread area because of sidewall flexing. Consult your
authorized dealer for radial tire repairs.
Compact Spare Tire — If Equipped
The compact spare is for temporary emergency use with
radial tires. It is engineered to be used on your style
vehicle only. Since this tire has limited tread life, the
original tire should be repaired (or replaced) and rein-
stalled at the first opportunity.

7. If the vehicle is equipped with Sentry KeyImmobi-
lizer, turn the ignition switch to the ON position for three
seconds before moving the ignition switch to the START
position.
8. Start the engine in the vehicle that has the booster
battery, let the engine idle a few minutes, and then start
the engine in the vehicle with the discharged battery.
9. When removing the jumper cables, reverse the above
sequence exactly. Be careful of the moving belts and fan.

Engine Oil Filter Selection
All of this manufacturer’s engines have a full-flow type
disposable oil filter. Use a filter of this type for replace-
ment. The quality of replacement filters varies consider-
ably. Only high-quality filters should be used to assure
most efficient service. MOPARengine oil filters are
high-quality oil filters and are recommended.
Engine Air Cleaner Filter
Refer to the “Maintenance Schedule” in Section 8 for the
proper maintenance intervals.
NOTE: Be sure to follow the “dusty or off-road condi-
tions” maintenance interval if applicable.

Windshield Wiper Blades
Clean the rubber edges of the wiper blades and the
windshield periodically with a sponge or soft cloth and a
mild non-abrasive cleaner or use the washer solvent. This
will 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 remove frost or ice from
the windshield. Keep the blade rubber out of contact with
petroleum products such as engine oil, gasoline, etc.
Adding Washer Fluid
The windshield and rear window washers share the same
fluid reservoir. The fluid reservoir is located in the front
of the engine compartment. Be sure to check the fluid
level in the reservoir at regular intervals. Fill the reservoirwith windshield washer solvent (not radiator antifreeze)
and operate the system for a few seconds to flush out the
residual water.
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 climate. This
rating information can be found on most washer fluid
containers.
