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.
²When 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 brakes,
axle, engine, transmission, steering, suspension, chas-
sis structure or tires.
²Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.
²Vehicles with trailers should not be parked on a grade.
When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle automatic transmission in
PARK. Always, block or9chock9the trailer wheels.
²GCWR must not be exceeded.
²Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR

WARNING!
Carefully follow these tire changing warnings to
help prevent personal injury or damage to your
vehicle:
²Always park on a firm, level surface as far from
the edge of the roadway as possible before raising
the vehicle.
²Block the wheel diagonally opposite the wheel to
be raised.
²Set the parking brake firmly and set an automatic
transmission in park; a manual transmission in
reverse.
WARNING!
Carefully follow these tire changing warnings to
help prevent personal injury or damage to your
vehicle:
²Never start or run the engine with the vehicle on a
jack.
²Do not let anyone sit in the vehicle when it is on a
jack.
²Do not get under the vehicle when it is on a jack.
²Only use the jack in the positions indicated and
for lifting this vehicle during a tire change.
²If working on or near a roadway, be extremely
careful of motor traffic.
²To assure that spare tires, flat or inflated are
securely stowed, spares must be stowed with the
valve stem facing the ground.
²Turn on the Hazard warning flasher.
416 WHAT TO DO IN EMERGENCIES

CAUTION!
Do not attempt to raise the vehicle by jacking on
locations other than those indicated in Step 5.
6. Place the wrench on the jack screw and turn to the
right until the jack head is properly engaged in the
described location.Do not raise the vehicle until you are
sure the jack is securely engaged.
7. Raise the vehicle by turning the jack screw to the right,
using the swivel wrench. 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.
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.
8. Remove the wheel lug nuts, for vehicles with wheel
covers, remove the cover from the wheel by hand. Do not
pry the wheel cover off. Then pull the wheel off the hub.
9. Install the compact spare tire. Lightly tighten the lug
nuts. To avoid the risk of forcing the vehicle off the jack,
do not tighten the lug nuts fully until the vehicle has been
lowered.
NOTE:Do not install the wheel cover on the compact
spare.
Do not use a hammer or force to install the wheel covers.

of operation, and after each time a tire is changed, to
allow the wheel nuts to become properly set. All nuts
should first be firmly seated against the wheel. The nuts
should then be tightened to recommended torque.
Tighten the nuts to final torque in increments. Progress
around the bolt circle, tightening the nut opposite to the
nut just previously tightened until final torque is
achieved. Recommended torque is 95 ft lbs (130 N´m).
Secure The Spare Tire As Follows:
1. To stow the compact spare tire/cover assembly on
vehicles equipped with Stow 'n Go seating, assemble the
winch handle extensions to form a ªT' and fit the winch
ªTº handle over the drive nut. Rotate the nut to the left
until the winch mechanism stops turning freely. This will
allow enough slack in the cable to allow you to pull the
wheel spacer out from under the vehicle.
WARNING!
A loose compact spare tire/cover assembly, thrown
forward in a collision or hard stop could endanger
the occupants of the vehicle. Always stow the com-
pact spare tire with the cover assembly in the place
provided.
CAUTION!
The winch mechanism is designed for use with the
winch ªTº handle only. Use of an air wrench or other
power tools is not recommended and can damage the
winch.

4. Disengage the two retaining tabs that secure the filter
cover to the HVAC housing and remove the cover.
5. Remove the A/C Air Filter by pulling it straight out of
the housing.6. Install the A/C Air Filter with the arrow on the filter
pointing toward the floor. When installing the filter
cover, make sure the retaining tabs fully engage the
cover.
CAUTION!
The A/C Air Filter is labeled with an arrow to
indicate airflow direction through the filter. Failure
to properly install the filter will result in the need to
replace it more often.
7. Rotate the glove box door back into position.
POWER STEERING Ð FLUID CHECK
Checking the power steering fluid level at a defined
service interval is not required. The fluid should only be
checked if a leak is suspected, abnormal noises are

²Do 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 those hoses nearest to high
heat sources such as the exhaust manifold. Inspect hose
routing to be sure hoses do not come in contact with any
heat source or moving component which 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 wear or damage that could cause failure.FUEL SYSTEM CONNECTIONS
The Electronic Fuel Injection high-pressure fuel system's
hoses and quick connect fittings have unique material
characteristics that provide adequate sealing and resist
attack by deteriorated gasoline.
You are urged to use only the manufacture specified
hoses with quick connect fittings, or their equivalent in
material and specification, in any fuel system servicing. It
is mandatory to replace any damaged hoses or quick
connect fittings that have been removed during service.
Care should be taken in installing quick connect fittings
to ensure they are properly installed and fully connected.
See your authorized dealer for service.

BRAKES
In order to assure brake system performance, all brake
system components should be inspected periodically.
Suggested service intervals can be found in the Mainte-
nance Schedules.
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 wouldn't have your full
braking capacity in an emergency.
Brake And Power Steering Hoses
When the vehicle is serviced for scheduled maintenance,
inspect surface of hoses and nylon tubing for evidence of
heat and mechanical damage. Hard and brittle rubber,cracking, tears, cuts, abrasion, and excessive swelling
indicate deterioration of the rubber. Particular attention
should be made to examining those hose surfaces nearest
to high heat sources, such as the exhaust manifold.
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.
NOTE:Often, fluid such as oil, power steering fluid,
and brake fluid are used during assembly plant opera-
tions to facilitate the assembly of hoses to couplings.
Therefore, oil wetness at the hose-coupling area is not
necessarily an indication of leakage. Actual dripping of
hot fluid when systems are under pressure (during
vehicle operation), should be noted before hose is re-
placed based on leakage.
