8. Remove all the wheel
nuts and the at tire.
{CAUTION:
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, 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 5-88.9. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and spare wheel.
10. Place the spare tire on the wheel-mounting surface.
{CAUTION:
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.
11. Put the nuts on by hand. Make sure the cone
shaped end is toward the wheel.
12. Tighten each nut by hand until the wheel is held
against the hub. If a nut cannot be turned by
hand, use the wheel wrench and see your dealer
as soon as possible.

Secondary Latch System
This vehicle may have an underbody-mounted tire hoist
assembly equipped with a secondary latch system. It is
designed to stop the spare tire, if the vehicle has one,
from suddenly falling off the 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 5-100for 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 under spare.
To release the spare tire from the secondary latch:
1. Check under the
vehicle to see if the
cable is visible. If it is
not visible, proceed
to Step 6.

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.

Spare Tire
This vehicle may have a spare tire. Although the spare
tire was fully inated when the vehicle was new, it can
lose air after a time. Check the ination pressure
regularly. SeeInflation - Tire Pressure on page 5-60
andLoading the Vehicle on page 4-31for information
regarding proper tire ination and loading your vehicle.
For instruction on how to remove, install or store a spare
tire, seeRemoving the Flat Tire and Installing the Spare
Tire on page 5-92andStoring a Flat or Spare Tire and
Tools on page 5-100.
After installing the spare tire on your vehicle, you should
stop as soon as possible and make sure the spare is
correctly inated. The spare tire is made to perform well
at speeds up to 70 mph (112 km/h) at the recommended
ination pressure, so you can nish your trip.
Have the damaged or at road tire repaired or replaced
as soon as you can and installed back onto your vehicle.
This way, a spare tire will be available in case you need it
again. Do not mix tires and wheels of different sizes,
because they will not t. Keep your spare tire and its
wheel together.
