Installing A Trailer Hitch
NOTE:If you install a trailer hitch after you purchase
the vehicle, you must install a Moparspare tire hold
down kit. The kit will allow you to properly secure the
spare tire and jack assembly.
WARNING!
Do not operate the vehicle without a properly se-
cured tire and jack assembly. Any loose items may be
thrown forward in a collision or hard stop and strike
occupants, causing serious or fatal injury.
Trailer Hitch Classification
The following chart provides the industry standard for
the maximum trailer weight a given trailer hitch class can
tow and should be used to assist you in selecting the
correct trailer hitch for your intended towing condition.Refer to the Trailer Towing Weights (Maximum Trailer
Weight Ratings) chart for the Maximum GTW towable
for your given drivetrain.

290 STARTING AND OPERATING

Towing Requirements
To promote proper break-in of your new vehicle driv-
etrain components, the following guidelines are recom-
mended:
CAUTION!
•Avoid towing a trailer for the first 500 mi (805 km)
of vehicle operation. Doing so may damage your
vehicle.
•During the first 500 mi (805 km) of trailer towing,
limit your speed to 50 mph (80 km/h).
Perform the maintenance listed in Section 8 of this
manual. When towing a trailer, never exceed the GAWR
or GCWR ratings.
WARNING!
Improper towing can lead to an injury accident.
Follow these guidelines to make your trailer towing
as safe as possible:
Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have an accident.
•When hauling cargo or towing a trailer, do not over-
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to the
brakes, axle, engine, transmission, steering, suspen-
sion, chassis structure or tires.
STARTING AND OPERATING 293

•Turn on the Hazard Warning Flasher.
•Block both the front and rear
of the wheel diagonally oppo-
site the jacking position. For
example, if changing the right
front tire, block the left rear
wheel.
•Passengers should not remain in the vehicle while the
vehicle is being jacked.
Jacking Instructions
WARNING!
Carefully follow these tire changing warnings to help prevent
personal injury or damage to your vehicle:
•Always park on a firm, level surface as far from the edge of
the roadway as possible before raising the vehicle.
•Block the wheel diagonally opposite the wheel to be raised.
•Set the parking brake firmly and set an automatic transmis-
sion in park; a manual transmission in reverse.
•Never start or run the engine with the vehicle on a jack.
•Do not let anyone sit in the vehicle when it is on a jack.
•Do not get under the vehicle when it is on a jack.
•Only use the jack in the positions indicated and for lifting
this vehicle during a tire change.
•If working on or near a roadway, be extremely careful of
motor traffic.
•To assure that spare tires, flat or inflated are securely stowed,
spares must be stowed with the valve stem facing the
ground.
•Turn on the Hazard warning flasher.
Jack Warning Label
306 WHAT TO DO IN EMERGENCIES

3. There are two front jacking locations and two rear
jacking locations on each side of the body. The front
locations are outlined by two triangular cutouts, the rear
ones by two rectangular cutouts. For vehicles equipped
with plastic trim, the plastic has been cut away to expose
the jacking locations in the body.
Do not raise the vehicle until you are sure the jack is
securely engaged.
4. Turn the jack screw to the left until the jack can be
placed under the jacking location. Once the jack is
positioned, turn the jack screw to the right until the jack
head is properly engaged with the lift area closest to the
wheel to be changed.WARNING!
Raising the vehicle higher than necessary can make
the vehicle less stable. It could slip off the jack and
hurt someone near it. Raise the vehicle only enough
to remove the tire.
5. Using the swivel wrench raise the vehicle by turning
the jack screw to the right. Raise the vehicle only until the
tire just clears the surface and enough clearance is
obtained to install the spare tire. Minimum tire lift
provides maximum stability.
6. Remove the wheel nuts and pull the wheel and wheel
covers, where applicable, off the hub. Install the spare
wheel and wheel nuts with the cone shaped end of the
nuts toward the wheel. Lightly tighten the nuts. To avoid
the risk of forcing the vehicle off the jack, do not tighten
the nuts fully until the vehicle has been lowered.
308 WHAT TO DO IN EMERGENCIES

WARNING!
To avoid possible personal injury, handle the wheel
covers with care to avoid contact with any sharp
edges.
NOTE:The wheel cover is held on the wheel by the
wheel nuts. When reinstalling the original wheel, prop-
erly align the wheel cover to the valve stem, place the
wheel cover onto the wheel, then install the wheel nuts.
7. Lower the vehicle by turning the jack screw to the left.
8. Finish tightening the nuts. Push down on the wrench
while tightening the wheel nuts. Alternate nuts until each
nut has been tightened twice. Correct wheel nut torque is
100 ft lbs (135 N·m). If you doubt that you have tightened
the nuts correctly, have them checked with a torque
wrench by your authorized dealer or service station.9. Remove the wheel blocks and lower the jack until it is
free. Reassemble the lug wrench to the jack assembly and
stow it in the spare tire area. Secure the assembly using
the means provided.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided.
10. Place the deflated (flat) tire in the cargo area,have the
tire repaired or replaced as soon as possible.
WHAT TO DO IN EMERGENCIES 309

All Transaxles
CAUTION!
If the vehicle being towed requires steering, the
ignition switch must be in the ACC position, not in
the LOCK position.
Do not attempt to use sling type equipment when
towing. When securing the vehicle to a flat bed truck,
do not attach to front or rear suspension components.
Damage to your vehicle may result from improper
towing.
If it is necessary to use the accessories while being towed
(wipers, defrosters, etc.), the key must be in the ON
position, not the ACC position. Make certain the trans-
axle remains in NEUTRAL.
Without The Ignition Key
Special care must be taken when the vehicle is towed
with the ignition in the LOCK position. A dolly should be
used under the front wheels if the rear wheels are raised.
Proper towing equipment is necessary to prevent dam-
age to the vehicle.
Battery power is required to release the brake/
transmission interlock system. There is a removable plug
in the right side of the shifter housing that allows you to
insert your finger to override the system.
Towing This Vehicle Behind Another Vehicle (Flat
Towing With All Four Wheels On The Ground)
CAUTION!
DO NOT flat tow this vehicle. Damage to the driv-
etrain will result.
314 WHAT TO DO IN EMERGENCIES

•Do not change the thermostat for summer or winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory coolant performance, poor gas
mileage, and increased emissions.
Hoses And Vacuum/Vapor Harnesses
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, tears, cuts, abrasions, and exces-
sive swelling indicate deterioration of the rubber.
Pay particular attention to the hoses nearest to high heat
sources such as the exhaust manifold. Inspect hose rout-
ing to be sure hoses do not touch any heat source or
moving component that may cause heat damage or
mechanical wear.
Ensure nylon tubing in these areas has not melted or
collapsed.Inspect all hose connections such as clamps and cou-
plings, to make sure they are secure and no leaks are
present.
Components should be replaced immediately if there is
any evidence of degradation that could cause failure.Fuel System Connections
Electronic Fuel Injection high pressure fuel systems are
designed with tubes and special connects, connections
and clamps which have unique material characteristics to
provide adequate sealing and resist attack by deterio-
rated gasoline.
You are urged to use only the manufacturer’s-specified
tubes, connections and clamps, or their equivalent in
material and specification, in any fuel system servicing.
340 MAINTAINING YOUR VEHICLE

Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Refer to “Maintenance Schedule” under Section 8.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You would not have your full
braking capacity in an emergency.
Brake And Power Steering System Hoses
When servicing the vehicle for scheduled maintenance,
inspect the surface of the hoses and nylon tubing for
evidence of heat and mechanical damage. Hard andbrittle rubber, cracking, tears, cuts, abrasions, and exces-
sive swelling suggest deterioration of the rubber. Particu-
lar attention should be made to examining those hose
surfaces nearest to high heat sources, such as the exhaust
manifold.
Inspect all hose clamps and couplings to make sure they
are secure and no leaks are present.
Ensure nylon tubing in these areas has not melted or
collapsed.
NOTE:Often, fluids such as oil, power steering fluid,
and brake fluid are used during assembly plant opera-
tions to ease the assembly of hoses to couplings. There-
fore, oil wetness at the hose-coupling area is not neces-
sarily an indication of leakage. Actual dripping of hot
fluid when systems are under pressure (during vehicle
operation) should be noted before a hose is replaced
based on leakage.
