Changing a Flat Tire
If your vehicle is a Two-mode Hybrid, see the Two-mode
Hybrid manual for more information.
If a tire goes at, avoid further tire and wheel damage
by driving slowly to a level place. Turn on the hazard
warning ashers. SeeHazard Warning Flashers
on page 3-6.
{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. If you have a four-wheel-drive vehicle,
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.
6. Put the wheel 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 the vehicle has a at tire (B), use the following
example as a guide to assist you in the placement
of wheel blocks (A).

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.
5. 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 5-99for more information.

hook that allows you to
pull the hoist cable
towards you, to assist
in reaching the
spare tire.

Removing the Flat Tire and
Installing the Spare Tire
1. Do a safety check before proceeding. SeeChanging
a Flat Tire on page 5-86for more information.
2. If your vehicle has a center cap that covers the wheel
fasteners, place the chisel end of the wheel wrench
in the slot on the wheel and gently pry the cap out.
If the wheel has a bolt-on hub cap, loosen
the plastic nut caps by turning the wheel wrench
counterclockwise. The plastic nut caps will be
retained in the hub cap after it is removed from the
wheel.3. Use the wheel wrench to loosen all the wheel nuts.
Turn the wheel wrench counterclockwise to loosen
the wheel nuts. Do not remove the wheel nuts yet.

Front Tire Flat:If the at tire is on a front tire of the
vehicle, you will need to use the jack handle and only
one jack handle extension. Attach the wheel wrench
to the jack handle extension. Attach the jack handle
to the jack (A). Position the jack on the frame behind
the at tire where the frame sections overlap. 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 clear the ground.Front Position – 2500 Models
Rear Position – 1500 Models
5-94

Rear Tire Flat:If the at tire is on a rear tire of the
vehicle, you will need to use the jack handle (B) and
both jack handle extensions (C). Attach the wheel
wrench (D) to the jack handle extensions (C). Attach
the jack handle (B) to the jack (A). Use the jacking
pad provided on the rear axle. Turn the wheel
wrench (D) clockwise to raise the vehicle. Raise the
vehicle far enough off the ground so there is enough
room for the spare tire to clear the ground.
{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. Rear Position – All Other Models

10. Turn the wheel wrench counterclockwise to lower
the vehicle. Lower the jack completely.
11. Tighten the nuts rmly in a crisscross sequence as
shown by turning the wheel wrench clockwise.
{CAUTION:
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 specication
CAUTION: (Continued)
CAUTION: (Continued)
after replacing. Follow the torque specication
supplied by the aftermarket manufacturer when
using accessory locking wheel nuts. See
Capacities and Specifications on page 5-122for
original equipment wheel nut torque specications.
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
specication. SeeCapacities and Specifications on
page 5-122for the wheel nut torque specication.
When you reinstall the regular wheel and tire, you must
also reinstall either the center cap or the bolt-on hub
cap, depending on which your vehicle has.
For center caps, line up the tab on the center cap
with the slot in the wheel. The cap only goes in
one way. Place the cap on the wheel and press until
it snaps into place.
For bolt-on hub caps, line up the plastic nut caps
with the wheel nuts and tighten clockwise by
hand to get them started. Then tighten with the
wheel wrench until snug.

Secondary Latch System
Your vehicle has an underbody-mounted tire hoist
assembly equipped with a secondary latch system. It is
designed to stop the spare tire from suddenly falling off
your 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 on page 5-102.
{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.To release the spare tire from the secondary latch:
1. Check under the
vehicle to see if the
cable end is visible. If
the cable is not visible
proceed to Step 6.
2. If it is visible, rst try to tighten the cable by turning
the wheel wrench clockwise until you hear two clicks
or feel it skip twice. You cannot overtighten the cable.
3. Loosen the cable by turning the wrench
counterclockwise three or four turns.
