{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.6. Raise the vehicle by turning the jack handle
clockwise. Raise the vehicle far enough off

accident. When you change a wheel,
remove any rust or dirt from the places
where the wheel attaches to the vehicle.

CAUTION: (Continued)
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

surface.
{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.
10. Put the nuts on by hand. Make sure the
rounded end is toward the wheel.
11. Tighten each nut by hand until the wheel is
held against the hub. If a nut cannot be

{CAUTION:
Incorrect wheel nuts or improperly
tightened wheel nuts can cause the wheel
to come loose and even come off. This
could lead to an accident. Be sure to use
the correct wheel nuts. If you have to
replace them, be sure to get new original
equipment wheel nuts. Stop somewhere
as soon as you can and have the nuts
tightened with a torque wrench to the
proper torque specication. See
Capacities and Specifications on page 474
for wheel nut torque specication.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. See
Capacities and Specifications on page 474for
the wheel nut torque specication.
13. Use the wrench to
tighten the wheel
nuts rmly in a
crisscross sequence
as shown.

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 if the cable holding
the spare tire is damaged. For the secondary
latch to work, the tire must be stored with the valve
stem pointing up. SeeStoring a Flat or Spare
Tire and Tools on page 450for instructions
on storing the spare or at tire correctly.
{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.
{CAUTION:
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 the spare.
446

To release the spare tire from the secondary latch,
do the following:
1. Check under the
vehicle to see if the
cable is visible. If
it is not visible,
proceed to Step 6.2. If 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 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 2 ofRemoving the Spare
Tire and Tools on page 438.
5. Turn the wrench counterclockwise until
approximately 6 inches (15 cm) of cable
is exposed.
447

6. Attach the jack handle, extension(s) and the
wheel wrench to the jack and place it under
the vehicle towards the front of the rear
bumper. Position the center lift point of the
jack under the center of the spare tire.
7. Turn the wrench clockwise to raise the jack
until it lifts the end tting.
8. Continue raising the jack until the spare tire
stops moving upward and is held rmly in
place. The secondary latch has released and
the spare tire is balancing on the jack.9. 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.
10. Disconnect the jack handle from the jack and
carefully remove the jack. Use one hand to
push against the spare while rmly pulling the
jack out from under the spare tire with the
other hand.
11. If the spare tire is
hanging from the
cable, insert
the socket end of
the extension
into the hoist shaft
hole on a 45 degree
angle downward.
448

12. Be sure that the socket end of the extension
connects to the hoist shaft.
Turn the wheel wrench counterclockwise to
lower the spare the rest of the way.
13. Tilt the retainer at the end of the cable and
pull it through the wheel opening. Pull the
tire out from under the vehicle.Notice:If you drive away before the spare tire
or secondary latch system cable has been
reinstalled, you could damage your vehicle.
Always reinstall this cable before driving your
vehicle.
14. Turn the wheel wrench clockwise to raise the
cable back up if the cable is hanging under
the vehicle.
Have the hoist assembly inspected as soon as
you can. You will not be able to store a spare tire
using the hoist assembly until it has been
repaired or replaced.
449

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.
{CAUTION:
The underbody-mounted spare tire needs
to be stored with the valve stem pointing
up. If the spare tire is stored with the
valve stem pointing downward, its
secondary latch will not work properly
and the spare tire could loosen and
suddenly fall from your vehicle. If this
happened when your vehicle was being
driven, the tire might contact a person or
another vehicle, causing injury and, of
course, damage to itself as well. Be sure
the underbody-mounted spare tire is
stored with its valve stem pointing up.
Notice:An aluminum wheel with a at tire
should always be stored under the vehicle with
the hoist. However, storing it that way for an
extended period could damage the wheel.
To avoid this, always stow the wheel properly
with the valve stem pointing up and have
the wheel repaired as soon as possible.
