Practical hints
Flat tire
Lifting the vehicle
Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
or other sizable objects.
One wheel chock is included with
vehicle tool kit (
page 373).
When changing wheel on a level surface:

Place the wheel chock (located in the
vehicle tool kit) in front of and another
sizable object behind the wheel that is
diagonally opposite to the wheel being
changed.
When changing wheel on a hill:

Place the wheel chock and other size-
able object on the downhill side block-
ing both wheels of the other axle.

Take the two-piece wheel wrench and
the jack out of the vehicle tool kit
(page 373). Assemble wheel wrench.

On wheel to be changed, loosen but do
not yet remove the wheel bolts
(approximately one full turn with
wrench).
Warning!
G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. To help
avoid personal injury, use the jack only to lift
the vehicle during a wheel change. Never
get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always
firmly set parking brake and block wheels
before raising vehicle with jack.
Do not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use, es-
pecially on hills. Always try to use the jack
on level surface. Make sure the jack arm is
fully seated in the jack take-up bracket.
Always lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.

-5 Wheel bolts

Tighten the five wheel bolts evenly, fol-
lowing the diagonal sequence
illustrated ( 1 to 5 ), until all bolts are
tight. Observe a tightening torque of
80 lb-ft (110 Nm). Before storing the jack, it should be fully
collapsed, with handle folded in (storage
position) (
page 374).

Store the jack, the damaged wheel and
the other vehicle tools in the wheel well
below the trunk floor (
page 375).
Warning!
G
Inflate spare wheel with collapsible tire only
after the wheel is properly mounted.
Inflate the spare wheel tire using the electric
air pump before lowering the vehicle.
Warning!

Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
80 lb-ft (110 Nm).
