4. Using the combination wrench,
loosen but do not yet remove the
wheel bolts.
5. Remove protective cap from the
jack support tube. (The tube open­
ings are located directly behind the
front wheel housings and in front of
the rear wheel housings.)
6. Insert jack arm fully into the tube
hole up to the stop. Position the
jack so that it will always be vertical
as seen from the side, even on in­
clines. Jack up the vehicle until the
wheel is clear off the ground.
Warning!
The jack is designed exclusively
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 tire
change. Never get beneath the
vehicle while it is supported only
by the jack. Jack stands must be
used when working under the
vehicle. Always set parking
brake before raising vehicle with
jack.
7. Then unscrew wheel bolts com­
pletely. Keep bolt threads protected
from dirt and sand. While removing
last bolt, hold wheel against hub to
avoid paint damage on rim.
8. Remove wheel.
9. Screw the alignment bolt (sup­
plied in tool kit) into an upper
threaded hole.
10. Adjust the jack height so that the
wheel can be slipped on without
being lifted.
11. Install spare wheel on wheel hub.
Insert wheel bolts and tighten
them slightly. To avoid paint dam­
age, place wheel flat against hub
and hold it there while installing
first wheel bolt. Unscrew the
alignment stud to install the last
wheel bolt.
12. Lower car, remove jack and place
cap into the jack support tube.
