Changing Wheels - Mercedes-Benz 300 E 1990 Owner's Manual

Note:
Thoroughly clean the inner side of
the wheels any time you rotate the
wheels or wash vehicle underside.
The use of retread tires is not
recommended. Retread tires may
adversely affect the handling
characteristics and safety of the
vehicle.
Dented or bent rims cause tire
pressure loss and damage to the
tire beads. For this reason, check
rims for damage at regular inter­
vals.
The rim flanges must be checked
for wear before a tire is mounted.
Remove burrs, if there are any.

Changing Wheels

1. Move vehicle to a level area
which is a safe distance from
the roadway.
2. Set parking brake and turn on
hazard warning flasher.
3. Move selector lever to posi­
tion " 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 oppo­
site 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 in­
serting a srewdriver and pry­
ing it out. (The tube openings
are located directly behind the
front wheel housings and in
front of the rear wheel hous­
ings.)
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.
