Tire Chains
{WARNING
If your vehicle has P215/70R16,
P235/75R16, P265/70R17, P235/
50R18, or P265/65R18 size tires,
do not use tire chains. They can
damage your vehicle because
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.(Continued)
WARNING (Continued)
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, readjust,
or remove the device if it is
contacting your vehicle. Do not
spin the vehicle's wheels.
If you do find traction devices that
will fit, install them on the rear
tires. Notice:
If your vehicle has a tire
size other than P215/70R16, P235/
75R16, P265/70R17, P235/50R18,
or P265/65R18 use tire chains
only where legal and only when
you must. Use chains that are the
proper size for your tires. Install
them on the tires of the rear axle.
Do not use chains on the tires of
the front axle. Tighten them as
tightly as possible with the ends
securely fastened. Drive slowly
and follow the chain
manufacturer's instructions.
If you can hear the chains
contacting your vehicle, stop and
retighten them. If the contact
continues, slow down until it
stops. Driving too fast or
spinning the wheels with chains
on will damage your vehicle.

Vehicle Care 10-69
If a Tire Goes Flat
It is unusual for a tire to blowout
while driving, especially if the tires
are maintained properly. If air goes
out of a tire, it is much more likely to
leak out slowly. But if there ever is a
blowout, here are a few tips about
what to expect and what to do:
If a front tire fails, the flat tire
creates a drag that pulls the vehicle
toward that side. Take your foot off
the accelerator pedal and grip the
steering wheel firmly. Steer to
maintain lane position, and then
gently brake to a stop, well off the
road, if possible.A rear blowout, particularly on a
curve, acts much like a skid and
may require the same correction as
used in a skid. Stop pressing the
accelerator pedal and steer to
straighten the vehicle. It may be
very bumpy and noisy. Gently brake
to a stop, well off the road,
if possible.
{WARNING
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has been
driven on while severely
underinflated or flat may cause a
blowout and a serious crash.
Never attempt to re-inflate a tire
that has been driven on while
severely underinflated or flat.
Have your dealer or an authorized
tire service center repair or
replace the flat tire as soon
as possible.
{WARNING
Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the
appropriate safety equipment and
training. If a jack is provided with
the vehicle, it is designed only for
changing a flat tire. If it is used for
anything else, you or others could
be badly injured or killed if the
vehicle slips off the jack. If a jack
is provided with the vehicle, only
use it for changing a flat tire.
If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place, well off the road,
if possible. Turn on the hazard
warning flashers. See Hazard
Warning Flashers on page 6‑4.

{WARNING
Changing a tire can be
dangerous. The vehicle can slip
off the jack and roll over or fall
causing injury or death. Find a
level place to change the tire.
To help prevent the vehicle
from moving:1. Set the parking brake firmly.
2. Put an automatic transmission in P (Park) or a
manual transmission in
1 (First) or R (Reverse).
3. For four-wheel-drive vehicles, be sure the
transfer case is in a drive
gear– not in N (Neutral).
4. Turn off the engine and do not restart while the vehicle
is raised.
5. Do not allow passengers to remain in the vehicle.

get under a vehicle when it is
supported only by a jack.
{WARNING
Raising the vehicle with the jack
improperly positioned can
damage the vehicle and even
make the vehicle fall. To help
avoid personal injury and vehicle
damage, be sure to fit the jack lift
head into the proper location

{WARNING
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.
8. Remove any rust or dirt from thewheel bolts, mounting surfaces
and spare wheel.
9. Install the spare tire.
{WARNING
Never use oil or grease on bolts
or nuts because the nuts might
come loose. The vehicle's wheel
could fall off, causing a crash.

{WARNING
Wheel nuts that are improperly or
incorrectly tightened can cause
the wheels to become loose or
come off. The wheel nuts should
be tightened with a torque wrench
to the proper torque specification
after replacing. Follow the torque
specification supplied by the
aftermarket manufacturer when
using accessory locking wheel
nuts. SeeCapacities and
Specifications on page 12‑2 for
original equipment wheel nut
torque specifications.
Notice: Improperly tightened
wheel nuts can lead to brake
pulsation and rotor damage. To
avoid expensive brake repairs,
evenly tighten the wheel nuts in
the proper sequence and to the
proper torque specification. See
Capacities and Specifications on
page 12‑2 for the wheel nut
torque specification.
12. Tighten the wheel nuts firmly in a crisscross sequence, as
shown, by turning the wheel
wrench clockwise.
Reinstall the center cap when
the regular wheel and tire are
reinstalled. Place the cap on the
wheel and tap it into place until it is
flush with the wheel. The cap only
goes on one way. Be sure to line up
the tab on the center cap with the
indentation on the wheel.
Storing a Flat or Spare Tire
and Tools
{WARNING
Storing a jack, a tire, or other
equipment in the passenger
compartment of the vehicle could
cause injury. In a sudden stop or
collision, loose equipment could
strike someone. Store all these in
the proper place.
Notice: Storing an aluminum
wheel with a flat tire under your
vehicle for an extended period of
time or with the valve stem
pointing up can damage the
wheel. Always stow the wheel
with the valve stem pointing
down and have the wheel/tire
repaired as soon as possible.
Store the tire under the rear of the
vehicle in the spare tire carrier.
1. Put the tire on the ground at the rear of the vehicle with the valve
stem pointed down.

Secondary Latch System
This vehicle has an underbody‐
mounted tire hoist assembly that
has a secondary latch system. It is
designed to stop the spare tire from
suddenly falling off the vehicle. For
the secondary latch to work, the
spare must be installed with the
valve stem pointing down. See
“Storing a Flat or Spare Tire and
Tools”underTire Changing on
page 10‑70.
{WARNING
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. To release the spare tire from the
secondary latch:1. Check under the vehicle to see if
the cable end fitting is visible.
2. If the cable end fitting is not visible, proceed to Step 6.
If it is visible, first try to tighten
the cable by turning the wheel
wrench clockwise until you hear
two clicks or feel it skip twice.
The cable cannot be
overtightened. 3. Loosen the cable by turning the
wheel wrench counterclockwise
three or four turns.
4. Repeat this procedure at least two times. If the spare tire
lowers to the ground, continue
with Step 5 under “Storing a Flat
or Spare Tire and Tools” under
Tire Changing on page 10‑70.
5. Turn the wrench counterclockwise until
approximately 15 cm (6 in) of
cable is exposed.
6. Stand the wheel blocks on their shortest ends, with the backs
facing each other.

12. Reinsert the jack handle intothe jack. Lower the jack by
turning the wheel wrench
counterclockwise. Keep
lowering the jack until the
spare tire slides off the jack or
is hanging by the cable.
{WARNING
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
under the spare.
13. Disconnect the jack handle from the jack and carefully
remove the jack. Use one hand
to push against the spare while
firmly pulling the jack out from
under the spare tire with the
other hand. If the spare tire is hanging from
the cable, insert the hoist end
of the extension into the hoist
shaft hole in the bumper and
turn the wheel wrench
counterclockwise to lower the
spare the rest of the way.
14. Tilt the tire retainer at the end
of the cable and pull it through
the wheel opening. Pull the tire
out from under the vehicle. 15. If the cable is hanging under
the vehicle, turn the wheel
wrench clockwise to raise
the cable.
Have the hoist assembly
inspected as soon as you can.
A spare or flat tire can not be
stored using the hoist
assembly until it has been
replaced.
