Tire Chains
{CAUTION:
Do not use tire chains. There is not enough
clearance. Tire chains used on a vehicle
without the proper amount of clearance can
cause damage to the brakes, suspension, or
other vehicle parts. The area damaged by the
tire chains could cause you to lose control of
your vehicle and you or others may be injured
in a crash. Use another type of traction device
only if its manufacturer recommends it for use
on your vehicle and tire size combination and
road conditions. Follow that manufacturer’s
instructions. To help avoid damage to your
vehicle, drive slowly, re-adjust or remove the
device if it is contacting your vehicle, and do
not spin your wheels. If you do nd traction
devices that will t, install them on the rear
tires.
If a Tire Goes Flat
It is unusual for a tire to blowout while you are driving,
especially if you maintain your tires properly. SeeTires
on page 5-58. If air goes out of a tire, It is much more
likely to leak out slowly. But if you should ever have a
blowout, here are a few tips about what to expect and
what to do:
If a front tire fails, the at tire will create a drag that
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel rmly.
Steer to maintain lane position, and then gently brake
to a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you would use
in a skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop, well off the road if possible.
5-82

If a tire goes at, and your vehicle has a compact
spare tire, seeChanging a Flat Tire on page 5-102.
This information shows you how to use your vehicle’s
tire changing equipment and how to change a at
tire safely.
{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without
the appropriate safety equipment and training.
The jack provided with your vehicle is
designed only for changing a at tire. If it is
used for anything else, you or others could be
badly injured or killed if the vehicle slips off
the jack. Use the jack provided with your
vehicle only for changing a at tire.
Tire Sealant and Compressor Kit
If your vehicle has a factory installed tire sealant and
compressor kit, there is no spare tire, no tire changing
equipment and no place to store a tire.
If a tire goes at, avoid further tire and wheel damage
by driving slowly to a level place and stopping.
1. Turn on the hazard warning ashers. SeeHazard
Warning Flashers on page 3-6.
2. Park your vehicle. If your vehicle has an automatic
transmission, set the parking brake rmly and put
the shift lever in PARK (P). SeeShifting Into Park
(Automatic Transmission) on page 2-45. If your
vehicle has a manual transmission, move the
shift lever to REVERSE (R) and set the parking
brake rmly. SeeParking the Vehicle (Manual
Transmission) on page 2-47for additional
information.
3. Turn off the engine.
4. Inspect the at tire.
5-83

If the tire has been separated from the wheel, has
damaged sidewalls, or has a puncture larger than a
14inch (6 mm), the tire is too severely damaged for
the tire sealant and compressor kit to be effective.
SeeRoadside Service on page 7-7.
If the tire has a puncture less than a
14inch (6 mm)
in the tread area of the tire, seeTire Sealant and
Compressor Kit (With Sealant Selector Switch) on
page 5-84orTire Sealant and Compressor Kit
(Without Sealant Selector Switch) on page 5-93.
Tire Sealant and Compressor Kit
(With Sealant Selector Switch)
Your vehicle has a tire sealant and compressor kit that
is capable of temporarily sealing a puncture up to 6 mm in
the tread area of the tire. There is no jack or spare tire.
The kit inates the tire with liquid sealant and air. The tire
sealant and compressor kit can also be used to inate
an underinated tire. After the tire is inated to the
recommended ination pressure, seeInflation - Tire
Pressure on page 5-66for more information, the vehicle
must be driven for ve miles to distribute the sealant in
the tire and seal the puncture. After driving ve miles the
tire pressure must be rechecked and adjusted as needed.See Using the Tire Sealant and Compressor Kit later in
this section. Be sure to read and follow all of the tire
sealant and compressor kit instructions. The kit includes:
A. Selector Switch
B. On/Off Button
C. Air Pressure Gage
D. Tire Sealant
CanisterE. Air Compressor
Accessory Plug
F. Sealant/Air Hose
(Clear)
G. Air Only Hose
After temporarily sealing the tire sealant and compressor
kit, it is recommended to take your vehicle to an
authorized dealer/retailer as soon as possible. If the
sealant is removed within 100 miles (161 kilometers) of
driving, then it is easier to clean from the tire and you are
less likely to require a replacement tire.
5-84

Accessing the Tire Sealant and
Compressor Kit
A. Tire Sealant and Compressor Kit
B. Foam Container
C. Wing Nut
To access the tire sealant and compressor kit:

Tire Sealant
Read and follow the safe handling instructions on the
sealant canister.
The sealant can temporarily seal small punctures in the
tread area of the tire. The sealant cannot seal sidewall
damage, large punctures, or a tire that has unseated
from the wheel. SeeRoadside Service on page 7-7if
you need assistance.
The sealant can only be used to seal one tire. After
usage, the sealant canister and sealant lling hose
assembly must be replaced at a dealer/retailer. See
Removal and Installation of Sealant Canister later in
this section.
Check the tire sealant expiration date on the sealant
canister. The sealant might not be effective beyond
the expiration date. If needed, see your dealer/retailer
for a replacement canister.

hazard warning ashers. SeeHazard Warning Flashers
on page 3-6for more information.
{CAUTION:
Changing a tire can be dangerous. The vehicle
can slip off the jack and roll over or fall on you
or other people. You and they could be badly
injured or even killed. Find a level place to
change your tire. To help prevent the vehicle
from moving:
1. Set the parking brake rmly.
2. Put the shift lever in P (Park).
3. Turn off the engine and do not restart
while the vehicle is raised.
4. Do not allow passengers to remain in the
vehicle.
CAUTION: (Continued)
5-102

CAUTION: (Continued)
To be even more certain the vehicle will not
move, you should put blocks at the front and
rear of the tire farthest away from the one
being changed. That would be the tire, on the
other side, at the opposite end of the vehicle.
When your vehicle has a at tire, use the following
example as a guide to assist you in the placement of
wheel blocks.
The following information tells you how to use the jack
and change a tire.
