the roadway.
2. Set parking brake and turn on
hazard warning flasher.
3. With manual transmission, shift
gear shift lever to 1 st or reverse
gears, with automatic transmission,
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; 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 the protective cover from
the jack support tube opening by

ning of the cover and prying it out.
The tube openings are located di­
rectly behind the front wheel hous­
ings 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 al­
ways be vertical (plumb-line) as
seen from the side (see arrow),
even on inclines. Jack up the ve­
hicle until the wheel is clear off the
ground.
Warning!
The jack is designed exclusive­
ly 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 only by the
jack. Keep hands and feet
away from the area under the
lifted tire. Jack stands must
be used when working under
the vehicle. Always set park­
ing brake and block wheels
before raising vehicle with
jack.

pletely. Keep bolt threads protect­
ed from dirt and sand.

Insert wheel bolts and tighten
them slightly. To avoid paint dam­
age, place wheel flat against
hub and hold it there while in­
stalling first wheel bolt. Unscrew
