8. Lower the vehicle by turning the jack screw to the left,and remove the jack.
9. Finish tightening the lug nuts. Push down on the wrench while tightening for increased leverage. Alter-
nate nuts until each nut has been tightened twice.
Refer to “Torque Specifications” in this section for
correct lug nut torque.
10. Remove the jack assembly and wheel blocks.
11. Secure the tire, jack, and tools in their proper loca- tions.
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.
Road Tire Installation
1. Mount the road tire on the axle.
2. Install the remaining lug nuts with the cone shapedend of the nut toward the wheel. Lightly tighten the
lug nuts.
WARNING!
To avoid the risk of forcing the vehicle off the jack,
do not tighten the lug nuts fully until the vehicle has
been lowered. Failure to follow this warning may
result in serious injury.
3. Lower the vehicle to the ground by turning the jack handle counterclockwise.
4. Finish tightening the lug nuts. Push down on the wrench while at the end of the handle for increased
leverage. Tighten the lug nuts in a star pattern until
580 WHAT TO DO IN EMERGENCIES

If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
position, not the ACC position.
If the vehicle’s battery is discharged, refer to “Gear
Selector Override” in this section for instructions on
shifting the automatic transmission out of PARK for
towing.
CAUTION!
•Do not use sling type equipment when towing.
Vehicle damage may occur.
• When securing the vehicle to a flatbed truck, do not
attach to front or rear suspension components.
Damage to your vehicle may result from improper
towing.
Without The Ignition Key
Special care must be taken when the vehicle is towed
with the ignition in the LOCK position. The only ap-
proved method of towing without the ignition key is
with a flatbed truck. Proper towing equipment is neces-
sary to prevent damage to the vehicle.
Four–Wheel Drive Models
The manufacturer recommends towing with all wheels
OFF the ground. Acceptable methods are to tow the
vehicle on a flatbed or with one end of the vehicle raised
and the opposite end on a towing dolly.
590 WHAT TO DO IN EMERGENCIES

Air Conditioning Filter Replacement (A/C Air
Filter)
WARNING!
Do not remove the A/C air filter while the vehicle is
running, or while the ignition is in the ACC or
ON/RUN mode. With the A/C air filter removed and
the blower operating, the blower can contact hands
and may propel dirt and debris into your eyes,
resulting in personal injury.
The A/C air filter is located in the fresh air inlet behind
the glove box. Perform the following procedure to re-
place the filter:
1. Open the glove compartment and remove all contents.
2. Push in on the sides of the glove compartment and lower the door. 3. Pivot the glove compartment downward.
4. Disengage the two retaining tabs that secure the two
air filter access doors to the HVAC housing.
Glove Compartment
1 — Glove Compartment Travel Stops
2 — Glove Compartment
612 MAINTAINING YOUR VEHICLE

7. Install the A/C air filter with the air filter positionindicators pointing in the same direction as removal.
CAUTION!
The A/C air filter is identified 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.
8. Close A/C Air Filter access doors and secure retaining tabs.
9. Rotate the glove compartment door back into position.
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, decklid, sliding doors and hood hinges, should
be lubricated periodically with a lithium based grease,
such as MOPAR Spray White Lube 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 attention should also be given to hood latching
components to ensure proper function. When performing
other underhood services, the hood latch, release mecha-
nism and safety catch should be cleaned and lubricated.
The external lock cylinders should be lubricated twice a
year, preferably in the Fall and Spring. Apply a small
amount of a high quality lubricant, such as MOPAR Lock
Cylinder Lubricant directly into the lock cylinder.
614 MAINTAINING YOUR VEHICLE

Power Disc Brakes
Disc brakes do not require adjustment; however, several
hard stops during the break-in period are recommended
to seat the linings and wear off any foreign material.
Brake Master Cylinder
The fluid level in the master cylinders should be checked
whenever the vehicle is serviced. If necessary, add fluid
to bring level to the full level mark on the side of the
reservoir of the brake master cylinder. With disc brakes,
fluid level can be expected to fall as the brake pads wear.
If the brake fluid level is abnormally low, check system
for leaks.
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information.
WARNING!
•Use only manufacturer’s recommended brake
fluid. Refer to “Fluids, Lubricants, And Genuine
Parts” in “Maintaining Your Vehicle” for further
information. Using the wrong type of brake fluid
can severely damage your brake system and/or
impair its performance. The proper type of brake
fluid for your vehicle is also identified on the
original factory installed hydraulic master cylinder
reservoir.
• To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that has
been in a tightly closed container. Keep the master
cylinder reservoir cap secured at all times. Brake
fluid in a open container absorbs moisture from the
air resulting in a lower boiling point. This may

MAINTAINING YOUR VEHICLE 631

CAUTION!
If the fluid temperature is below 50°F (10°C) it may
not register on the dipstick. Do not add fluid until
the temperature is elevated enough to produce an
accurate reading. Run the engine at idle, in PARK, to
warm the fluid.
8. Reinstall the engine cover and snap it down securely onto the four mounting studs.
9. Check for leaks. Release the parking brake.
NOTE: To prevent dirt and water from entering the
transmission after checking or replenishing fluid, make
sure that the dipstick cap is properly reseated. It is
normal for the dipstick cap to spring back slightly from
its fully seated position, as long as its seal remains
engaged in the dipstick tube.
Fluid And Filter Changes
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
In addition, change the fluid and filter if the fluid
becomes contaminated (with water, etc.), or if the trans-
mission is disassembled for any reason.
Clutch Hydraulic System (Manual Transmission)
— If Equipped
The clutch hydraulic system is fed by a segregated
volume of fluid within the brake system master cylinder
reservoir. In the event of leakage or wear, use only the
manufacturer’s recommended brake fluid. Refer to “Flu-
ids, Lubricants, And Genuine Parts” in “Maintaining
Your Vehicle” for further information.
