Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for wear
and cracking. SeeScheduled Maintenance on page 6-4
for more information.
Replacement blades come in different types and are
removed in different ways. For proper type and length,
seeNormal Maintenance Replacement Parts on
page 6-13.
To replace the windshield wiper blade assembly do the
following:
1. Lift the wiper arm and turn the blade until it is
facing away from the windshield.
2. Squeeze the tabs (B) on each side of the wiper
blade assembly to remove the wiper arm (A)
from the blade (C).
Allowing the wiper blade arm to touch the windshield
when no wiper blade is installed could damage
the windshield. Any damage that occurs would not
be covered by your warranty. Do not allow the
wiper blade arm to touch the windshield.

There may be an accessory inator kit stored in the rear
compartment on the passenger’s side. It includes a
20-foot (6 m) hose with an air pressure gage and nozzle
adapters.
{CAUTION:
Inating something too much can make it
explode, and you or others could be injured.
Be sure to read the inator instructions, and
inate any object only to its recommended
pressure.
To use your accessory inator system, do the following:
1. Turn the ignition to ACCESSORY or RUN.
2. Attach the appropriate nozzle adapter, if required,
to the end of the hose that has the pressure gage.
3. Attach that end of the hose to the object you wish
to inate.
4. Remove the protective cap covering the outlet.
5. Attach the other end of the hose to the outlet.
6. Press the accessory inator switch. The light in the
switch will come on to show the system is working.If the accessory inator system does not turn on or the
light does not come on, the fuse may be blown or

page 5-96or see your dealer for service.
Your accessory inator will automatically shut off after
about 10 minutes. The light in the switch will blink. After
about one minute you can use the system again.
Press the switch and the indicator light will come on.
Notice:If you run the accessory inator longer than
30 minutes at a time, you could damage the inator.
The repairs would not be covered by your warranty.
Run the inator for short periods of time only.
After running the accessory inator for 30 minutes, wait

rmly in a crisscross
sequence, as shown.
Notice:Wheel covers will not t on your compact
spare. If you try to put a wheel cover on the compact
spare, you could damage the cover or the spare.
11. Do not try to put a wheel cover on the compact
spare tire. It will not t. Store the wheel cover
securely in the rear of the vehicle until you have the
at tire repaired or replaced.
Secondary Latch System
Your vehicle may have an underbody-mounted tire hoist
assembly equipped with a secondary latch system. It
is designed to stop a tire from suddenly falling off your
vehicle if the cable holding the spare tire is damaged.
For the secondary latch to work, the tire must be stowed
with the valve stem pointing down.Your vehicle uses the underbody tire hoist assembly to
store either the compact spare or a at road tire.
SeeStoring a Flat or Spare Tire and Tools on page 5-83
for instructions on storing the spare or at tire correctly.
{CAUTION:
Before beginning this procedure read all the
instructions. Failure to read and follow the
instructions could damage the hoist assembly
and you and others could get hurt. Read and
follow the instructions listed below.
{CAUTION:
Someone standing too close during the
procedure could be injured by the jack. If the
spare tire does not slide off the jack
completely, make sure no one is behind you or
on either side of you as you pull the jack out
from the spare.

5. Raise the tire fully against the underside of the
vehicle. Continue turning the folding wrench until
you feel more than two clicks. This indicates that the
compact spare tire is secure and the cable is
tight. The spare tire hoist cannot be overtightened.
6. Make sure the tire is stored securely. Push, pull (A),
and then try to turn (B) the tire. If the tire moves,
use the folding wrench to tighten the cable.Storing the Flat Tire on a
Front-Wheel-Drive Vehicle
The at tire is stored the same as the spare tire for
front-wheel-drive vehicles. Refer to “Storing the Spare
Tire” listed previously.
Storing the Flat Tire on an
All-Wheel-Drive Vehicle
1. Remove the tire storage bag and cable package
from the jack storage area.
2. Remove the small center cap by tapping the back
of the cap with the extension of the shaft, if the
vehicle has aluminum wheels.
3. Put the at tire in the tire storage bag and place it
in the rear storage area with the valve stem
pointing toward the front of the vehicle.

Storing the Tools
A. Strap
B. Bag and Tools
C. Jack
Put back all tools as they were stored in the jack
storage compartment and put the compartment cover
back on.To put the cover back on, line up the tabs on the right
of the cover with the slots in the cover opening. Push the
cover in place and push down the tab so that it rests
in the groove. This secures the cover in place.
Store the center cap or the plastic bolt-on wheel covers
until a full size tire is put back on the vehicle. When you
replace the compact spare with a full-size tire, reinstall
the bolt-on wheel covers or the center cap. Hand-tighten
them over the wheel nuts, using the folding wrench.
Compact Spare Tire
Although the compact spare tire was fully inated when
the vehicle was new, it can lose air after a time.
Check the ination pressure regularly. It should be
60 psi (420 kPa).
After installing the compact spare on the vehicle, stop
as soon as possible and make sure the spare tire
is correctly inated. The compact spare is made to
perform well at speeds up to 65 mph (105 km/h)
for distances up to 3,000 miles (5 000 km), so you can
nish your trip and have the full-size tire repaired or
replaced at your convenience. Of course, it is best
to replace the spare with a full-size tire as soon as
possible. The spare tire will last longer and be in good
shape in case it is needed again.
