Using the Tire Sealant and Compressor
Kit to Temporarily Seal and Inate a
Punctured Tire
Follow the directions closely for correct sealant usage.
When using the tire sealant and compressor kit during
cold temperatures, warm the kit in a heated environment
for 5 minutes. This will help to inate the tire faster.
Always do a safety check rst. SeeIf a Tire Goes Flat
on page 5-76. Do not remove any objects that have
penetrated the tire.
1. Remove the tire sealant and compressor kit from its
storage location. SeeTire Sealant and Compressor
Kit Storage on page 5-87.
2. Unwrap the sealant/air hose (F) and the power
plug (H).

19. Stop at a safe location and check the tire pressure.
Refer to Steps 1 through 11 under “Using the Tire
Sealant and Compressor Kit without Sealant to
Inate a Tire (Not Punctured).”
If the tire pressure has fallen more than 10 psi
(68 kPa) below the recommended ination pressure,
stop driving the vehicle. The tire is too severely
damaged and the tire sealant cannot seal the tire.
SeeRoadside Assistance Program on page 7-7.
If the tire pressure has not dropped more than
10 psi (68 kPa) from the recommended ination
pressure, inate the tire to the recommended
ination pressure.
20. Wipe off any sealant from the wheel, tire, and
vehicle.
21. Dispose of the used sealant canister (E) and sealant/
air hose (F) assembly at a local dealer/retailer or in
accordance with local state codes and practices.
22. Replace it with a new canister available from your
dealer/retailer.
23. After temporarily sealing a tire using the tire sealant
and compressor kit, take the vehicle to an authorized
dealer/retailer within a 100 miles (161 km) of driving
to have the tire repaired or replaced.Using the Tire Sealant and Compressor
Kit without Sealant to Inate a Tire
(Not Punctured)
To use the air compressor to inate a tire with air only
and not sealant:

Always do a safety check rst. SeeIf a Tire Goes Flat
on page 5-76.
1. Remove the tire sealant and compressor kit from its
storage location. SeeTire Sealant and Compressor
Kit Storage on page 5-87.
2. Unwrap the air only hose (G) and the power
plug (H).3. Place the kit on the ground.
Make sure the tire valve stem is positioned close to
the ground so the hose will reach it.
4. Remove the tire valve stem cap from the at tire by
turning it counterclockwise.
5. Attach the air only hose (G) onto the tire valve stem
by turning it clockwise until it is tight.
6. Plug the power plug (H) into the accessory power
outlet in the vehicle. Unplug all items from other
accessory power outlets. SeeAccessory Power
Outlet(s) on page 3-18.
If the vehicle has an accessory power outlet, do not
use the cigarette lighter.
If the vehicle only has a cigarette lighter, use the
cigarette lighter.
Do not pinch the power plug cord in the door or
window.

5. Tilt the retainer at the end of the cable when the
tire has been completely lowered, and pull it
through the wheel opening.
6. Pull the tire out from under the vehicle.Notice:If you drive away before the spare tire or
secondary latch system cable has been reinstalled,
you could damage your vehicle. Always reinstall
this cable before driving your vehicle.
7. Put the spare tire near the at tire.
Removing the Flat Tire and
Installing the Spare Tire
1. Do a safety check before proceeding. SeeChanging
a Flat Tire on page 5-88for more information.
2. Use the at end of the wheel wrench to carefully
pry off the center cap.

Secondary Latch System
This vehicle may have an underbody-mounted tire hoist
assembly equipped with a secondary latch system. It is
designed to stop the spare tire, if the vehicle has one,
from suddenly falling off the vehicle if the cable holding
the spare tire is damaged. For the secondary latch to
work, the tire must be stored with the valve stem pointing
up. SeeStoring a Flat or Spare Tire and Tools on
page 5-100for 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 next.
{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 under spare.
To release the spare tire from the secondary latch:
1. Check under the
vehicle to see if the
cable is visible. If it is
not visible, proceed
to Step 6.

1. Attach the handle (A), wheel wrench (B), and
extension (D) in the slots provided.
2. Roll up the instruction label (C) and return to the
slot in the tool kit.
3. Assemble the wheel blocks (F) to the jack.
4. Turn the knob (E) on the jack clockwise to raise the
jack head.
5. Return the rear seat to its proper position.
Spare Tire
This vehicle may have a spare tire. Although the spare
tire was fully inated when the vehicle was new, it can
lose air after a time. Check the ination pressure
regularly. SeeInflation - Tire Pressure on page 5-60
andLoading the Vehicle on page 4-31for information
regarding proper tire ination and loading your vehicle.
For instruction on how to remove, install or store a spare
tire, seeRemoving the Flat Tire and Installing the Spare
Tire on page 5-92andStoring a Flat or Spare Tire and
Tools on page 5-100.
After installing the spare tire on your vehicle, you should
stop as soon as possible and make sure the spare is
correctly inated. The spare tire is made to perform well
at speeds up to 70 mph (112 km/h) at the recommended
ination pressure, so you can nish your trip.
Have the damaged or at road tire repaired or replaced
as soon as you can and installed back onto your vehicle.
This way, a spare tire will be available in case you need it
again. Do not mix tires and wheels of different sizes,
because they will not t. Keep your spare tire and its
wheel together.
5-102

Washing Your Vehicle
The best way to preserve the vehicle’s nish is to keep
it clean by washing it often.
Notice:Certain cleaners contain chemicals that can
damage the emblems or nameplates on the vehicle.
Check the cleaning product label. If it states that
it should not be used on plastic parts, do not use it
on the vehicle or damage may occur and it would
not be covered by the warranty.
Do not wash the vehicle in direct sunlight. Use a car
washing soap. Do not use cleaning agents that
are petroleum based or that contain acid or abrasives,
as they can damage the paint, metal or plastic on
the vehicle. Approved cleaning products can be obtained
from your dealer/retailer. Follow all manufacturers’
directions regarding correct product usage, necessary
safety precautions and appropriate disposal of any
vehicle care product.Rinse the vehicle well, before washing and after to
remove all cleaning agents completely. If they are
allowed to dry on the surface, they could stain.
Dry the nish with a soft, clean chamois or an all-cotton
towel to avoid surface scratches and water spotting.
High pressure car washes may cause water to enter the
vehicle. Avoid using high pressure washes closer than
12 inches (30 cm) to the surface of the vehicle. Use of
power washers exceeding 1,200 psi (8 274 kPa) can
result in damage or removal of paint and decals.
Cleaning Exterior Lamps/Lenses
Use only lukewarm or cold water, a soft cloth and a car
washing soap to clean exterior lamps and lenses.
Follow instructions underWashing Your Vehicle on
page 5-107.

Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to the
vehicle unless you check with your dealer/retailer
rst. Some electrical equipment can damage
the vehicle and the damage would not be covered
by the vehicle’s warranty. Some add-on electrical
equipment can keep other components from
working as they should.
Add-on equipment can drain the vehicle battery, even if
the vehicle is not operating.
The vehicle has an airbag system. Before attempting to
add anything electrical to the vehicle, seeServicing
Your Airbag-Equipped Vehicle on page 1-68.
Headlamps
The headlamp wiring is protected by four fuses. An
electrical overload will cause a lamp to go on and off.
If this happens, have the headlamp wiring checked
right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools. If the
overload is caused by some electrical problem, have it
xed.
Power Windows and Other Power
Options
Circuit breakers in the fuse block protect the power
windows and other power accessories. When the current
load is too heavy, the circuit breaker opens and closes,
protecting the circuit until the problem is xed or
goes away.
