Vehicles that have the Tire Pressure Monitor
System (TPMS) will need to have the TPMS
sensors reset after a tire rotation. See “TPMS
Sensor Identication Codes” underTire Pressure
Monitor System on page 490.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specications on page 546.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make 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 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 needed, to get all the rust or dirt off.
SeeChanging a Flat Tire on page 506.
When It Is Time for New Tires
One way to tell when it
is time for new tires is
to check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of tread
remaining. Some
commercial truck tires
may not have treadwear
indicators.
You need a new tire if any of the following
statements are true:
You can see the indicators at three or more
places around the tire.
You can see cord or fabric showing through
the tire’s rubber.
The tread or sidewall is cracked, cut or
snagged deep enough to show cord or fabric.
The tire has a bump, bulge, or split.
The tire has a puncture, cut, or other damage
that cannot be repaired well because of the
size or location of the damage.

If a Tire Goes Flat
It is unusual for a tire to blowout while you are
driving, especially if you maintain your vehicle’s
tires properly. 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.{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 the
jacking equipment to change a at tire safely.

To access the spare tire, refer to the following
graphics and instructions:
A. Hoist Assembly
B. Hoist Shaft
C. Hoist Shaft Access
Cover/HoleD. Jack Handle
Extensions
E. Wheel Wrench
F. Hoist CableG. Tire Retainer
H. Spare Tire (Valve
Stem Pointed Down)
I. Hoist Shaft
Access HoleJ. Hoist End of
Extension Tool
K. Spare Tire Lock
1. To reach the hoist shaft access cover (C),
you will rst need to remove the hitch cover.
Remove it by turning the two fasteners located
at the bottom of the cover counterclockwise
and then pull the cover down and rotate
towards you.
2. Remove the hoist shaft access cover (C) on
the bumper to access the spare tire lock (K).
509

5. Insert the open end
of the extension (J)
through the hole
in the rear
bumper (I) (hoist
shaft access hole).
Be sure the hoist end (J) of the extension (D)
connects to the hoist shaft (B). The ribbed
square end of the extension is used to lower
the spare tire.
6. Turn the wheel wrench (E) counterclockwise
to lower the spare tire (H) 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 518for more information.7. Use the wheel
wrench hook that
allows you to
pull the hoist cable
towards you, to
assist in reaching
the spare tire.
8. Tilt the tire
retainer (G) at the
end of the cable
when the tire
has been lowered,
so it can be
pulled up through
the wheel opening.
9. Put the spare tire near the at tire.
511

{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 needed,
to get all the rust or dirt off.
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. Put the wheel nuts back on with the rounded
end of the nuts toward the wheel after
mounting the spare tire.
8. Tighten each wheel nut by hand. Then use
the wheel wrench to tighten the nuts until the
wheel is held against the hub.
9. Turn the wheel wrench counterclockwise to
lower the vehicle. Lower the jack completely.
516

4. Repeat this procedure at least two times.
If the spare tire lowers to the ground,
continue with Step 5 ofRemoving the
Spare Tire and Tools on page 507.
5. If the spare tire does not lower, turn the wheel
wrench counterclockwise until approximately
6 inches (15 cm) of cable is exposed.
6. Stand the wheel blocks on their shortest ends,
with the backs facing each other.
7. Place the bottom
edge of the jack (A)
on the wheel
blocks (B),
separating them so
that the jack is
balanced securely.8. Attach the jack handle, extension, and wheel
wrench to the jack and place it (with the
wheel blocks) under the vehicle toward the
front of the rear bumper.

Storing a Flat or Spare Tire and
Tools
{CAUTION:
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
at tire under your vehicle for an extended
period of time or with the valve stem pointing
up may 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. Refer to the following graphics
and instructions to help you:
A. Hoist Assembly
B. Hoist Shaft
C. Hoist Shaft Access
Cover/HoleD. Jack Handle
Extensions
E. Wheel Wrench
F. Hoist Cable

Fabric/Carpet
Use a vacuum cleaner with a soft brush attachment
frequently to remove dust and loose dirt. A canister
vacuum with a beater bar in the nozzle may only be
used on oor carpet and carpeted oor mats. For
soils, always try to remove them rst with plain
water or club soda. Before cleaning, gently remove
as much of the soil as possible using one of the
following techniques:
For liquids: gently blot the remaining soil with a
paper towel. Allow the soil to absorb into the
paper towel until no more can be removed.
For solid dry soils: remove as much as possible
and then vacuum.
To clean, use the following instructions:
1. Saturate a lint-free, clean white cloth with
water or club soda.
2. Wring the cloth to remove excess moisture.3. Start on the outside edge of the soil and
gently rub toward the center. Continue
cleaning, using a clean area of the cloth each
time it becomes soiled.
4. Continue to gently rub the soiled area until the
cleaning cloth remains clean.
5. If the soil is not completely removed, use a
mild soap solution and repeat the cleaning
process that was used with plain water.
If any of the soil remains, a commercial fabric
cleaner or spot lifter may be necessary. When a
commercial upholstery cleaner or spot lifter is to be
used, test a small hidden area for colorfastness
rst. If the locally cleaned area gives any
impression that a ring formation may result, clean
the entire surface.
After the cleaning process has been completed, a
paper towel can be used to blot excess moisture
from the fabric or carpet.
