Tire Chains
{CAUTION:
If your vehicle has dual wheels or P265/75R16,
LT265/75R16, P265/70R17 or P275/55R20 size
tires, don’t use tire chains. They can damage
your vehicle because there’s 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
CAUTION: (Continued)
CAUTION: (Continued)
instructions. To help avoid damage to your
vehicle, drive slowly, readjust or remove the
device if it’s contacting your vehicle, and don’t
spin your wheels.
If you do nd traction devices that will t,
install them on the rear tires.″
Notice:If your vehicle does not have dual wheels
and is equipped with a tire size other than
P265/75R16, LT265/75R16, P265/70R17 or
P275/55R20, 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. Don’t 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.

If a Tire Goes Flat
It’s unusual for a tire to “blowout” while you’re driving,
especially if you maintain your tires properly. If air goes
out of a tire, it’s 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’d 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.{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.
If a tire goes at, the next part shows how to use your
jacking equipment to change a at tire safely.

Changing a Flat Tire
If a tire goes at, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your
hazard warning ashers.
{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 an automatic transmission shift lever in
PARK (P), or shift a manual transmission to
FIRST (1) or REVERSE (R).
3. If you have a four-wheel-drive vehicle,
be sure the transfer case is in a drive
gear—not in NEUTRAL.
CAUTION: (Continued)
CAUTION: (Continued)
4. Turn off the engine and do not restart
while the vehicle is raised.
5. Do not allow passengers to remain in
the vehicle.
To be even more certain the vehicle won’t
move, you can 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 you have a at tire, use the following as a guide
to assist you in the placement of the wheel blocks.
5-92

3. Remove the wheel blocks and the wheel block
retainer by turning the wing nut counterclockwise.
4. Remove the wing nut used to retain the storage
bag and tools by turning it counterclockwise.
You’ll use the jack handle extensions and the wheel
wrench to remove the underbody-mounted spare tire.

1. Open the spare tire lock cover on the bumper and
use the ignition key to remove the lock (if your
vehicle is equipped with a hoist lock (J)).
2. Assemble the wheel wrench (H) and the two jack
handle extensions (I) as shown.
5-95

3. Insert the hoist end
(open end) (F) of the
extension through
the hole (G) in the
rear bumper.
Be sure the hoist end of the extension connects to the
hoist shaft (E). The ribbed square end of the extension
is used to lower the spare tire.
4. Turn the wheel wrench (H) counterclockwise to
lower the spare tire to the ground. Continue to
turn the wheel wrench until the spare tire can be
pulled out from under the vehicle.
If the spare tire does not lower to the ground, the
secondary latch is engaged causing the tire
not to lower. SeeSecondary Latch System on
page 5-105.5. Use the wheel wrench
hook which allows you
to pull the hoist
cable towards you to
assist in reaching
the spare tire.
6. Tilt the retainer (D) at
the end of the cable
when the tire has been
lowered, so it can
be pulled up through
the wheel opening.
7. Put the spare tire near the at tire.

Removing the Flat Tire and
Installing the Spare Tire
Use the following pictures and instructions to remove
the at tire and raise the vehicle.
The tools you’ll be using include the bottle jack (A), the
wheel blocks (B), the jack handle (C), the jack handle
extensions (D), and the wheel wrench (E).1. If your vehicle has
wheel nut caps, loosen
them by turning the
wheel wrench
counterclockwise.
If the vehicle has a center cap with wheel nut caps,
the wheel nut caps are designed to stay with the
center cap after they are loosened. Remove
the entire center cap.
5-97

If the wheel has a smooth center cap, place the
chisel end of the wheel wrench in the slot on
the wheel, and gently pry out.
If the wheel has bolt-on wheel covers, loosen the
plastic nut caps by turning the wheel wrench
in a counterclockwise direction. If needed, nish
loosening them by hand. The nut caps will not come
off. Using the at end of the wheel wrench, pry
along the edge of the cover until it comes off.2. Use and turn the wheel wrench counterclockwise
to loosen the wheel nuts. Don’t remove the wheel
nuts yet.
Notice:If your vehicle has QUADRASTEER™ and
you use a jack to raise the vehicle without
positioning it correctly, you could damage the
QUADRASTEER™ system. When raising your
vehicle on a jack, avoid contact with tie rods and tie
rod boots.

C. Rear Location (All Series)
3. Position the jack under the vehicle as shown. If the
at tire is on the front of the vehicle (two-wheel-drive
1500 Series vehicles), position the jack under the
bracket attached to the vehicle’s frame, behind
the at tire. If the at tire is on the front of the
vehicle (all other models), position the jack on the
frame behind the at tire.
If the at tire is on the rear, position the jack under
the rear axle between the spring anchor and the
shock absorber bracket.If you have added a snow plow to the front of your
vehicle, lower the snow plow fully before raising
the vehicle.
{CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack you
could be badly injured or killed. Never get
under a vehicle when it is supported only
by a jack.
{CAUTION:
Raising your 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 t the
jack lift head into the proper location before
raising the vehicle. Jacking Locations
5-99

4. Make sure the jack head is positioned so that the
rear axle is resting securely between the grooves
that are on the jack head. Turn the wheel
wrench clockwise to raise the vehicle. Raise the
vehicle far enough off the ground so there is enough
room for the spare tire to t under the wheel well.5. Remove all the wheel
nuts and take off the
at tire.
{CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
the places where the wheel attaches to the
vehicle. In an emergency, you can use a cloth
or a paper towel to do this; but be sure to use
a scraper or wire brush later, if you need to, to
get all the rust or dirt off. Rear Position
5-101

6. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and spare wheel.
{CAUTION:
Never use oil or grease on studs or nuts. If
you do, the nuts might come loose. Your wheel
could fall off, causing a serious accident.7. After mounting the
spare, put the wheel
nuts back on with
the rounded end of the
nuts toward the
wheel.
8. Tighten each wheel nut by hand. Then use the
wheel wrench to tighten the nuts until the wheel
is held against the hub.
