Changing Wheels
1. Set parking brake.
2. Move selector lever to position
“ p . ,
3. Prevent vehicle from rolling away
by blocking wheels with wheel
chocks: When changing a wheel
on a hill, place chocks behind
each wheel of the axle opposite to
the axle to be worked on; on a
level road, place one chock in
front and one behind of the wheel
that is diagonally opposite to the
wheel being changed.
4. Using the combination wrench,
loosen but do not yet remove the
wheel bolts.
5. Clean jack supporting tube, if
necessary. (Jack tubes are behind
the front wheel housings and in
front of the rear wheel housings.)
6. Insert jack arm fully into tube hole
up to the stop. Position the jack
so that it will always be vertical as
seen from the side, even on
inclines. Jack up the vehicle until
the wheel is clear off the ground.
7. Then unscrew wheel bolts com­
pletely. Keep bolt threads pro­
tected from dirt and sand.
While removing last bolt, hold
wheel against axle to avoid paint
damage on rim.
8. Remove wheel.
9. Adjust the jack to allow the wheel
to be slipped on without being
lifted.
10. Slip on wheel and press against
wheel mounting flange. Turn in
wheel bolts.
To avoid paint damage, place
wheel flat against hub and hold it
there while installing first wheel
bolt.
11. Lower car and remove jack.
Tighten the five bolts evenly by
tightening every other bolt until
all the bolts are tight. Observe a
tightening torque of 110 Nm/
80 Ib-ft.
12. Correct tire pressure.
Tire pressure
A table (see fuel filler flap or last
page) lists the tire inflation pressures
specified for summer and winter tires
as well as for the varying operating
conditions.
