Changing Wheels - Mercedes-Benz 420 SEL 1986 Owner's Manual

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 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 oppo­
site to the wheel being changed.
4. Using the combination wrench,
loosen but do not yet remove the
wheel bolts.
5. Remove cap from the jack support
tube. (The tube openings are loca­
ted 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 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 du­
ring 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 vehic­
le.
7. Then unscrew wheel bolts com­
pletely. Keep bolt threads protec­
ted 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.
