Changing Wheels
1. Move vehicle to a level area which
is a safe distance from the road­
way.
2. Set parking brake and turn on
hazard warning flasher.
3. Move selector lever to position "P".
4. Prevent vehicle from rolling away
by blocking wheels with wheel
chocks or sizeable wood block or
stone (not supplied with vehicle).
When changing a wheel on a hill,
place chocks on the downhill side
of each wheel of the other axle.
76
On a level road, place one chock
in front of and one behind the
wheel that is diagonally opposite
to the wheel being changed.
5. Using the combination wrench,
loosen but do not yet remove the
wheel bolts.
6. Remove cap from the jack support
tube opening by inserting a screw
driver and prying it out. (The tube
openings are located directly
behind the front wheel housings
and in front of the rear wheel
housings.)
7. Insert jack arm fully into the tube
hole up to the stop.
8. Position the jack so that it will
always be vertical (plumb-line) as
seen from the side (see arrow),
even if the vehicle is parked on an
incline. Jack up the vehicle until
the wheel is clear off the ground.
Warning!
The jack is designed exclu­
sively for jacking up the
vehicle at the jack tubes built
into either side of the vehicle.
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 vehicle is raised.
Be certain that the jack is
always vertical when in use,
especially on hills. Lower the
vehicle onto sufficient capaci­
ty jackstands before working
under the vehicle.
