Changing Wheels - Mercedes-Benz Light Truck ML 320 Operator's Manual

Changing Wheels

Move vehicle to a level area which is a
safe distance from the roadway.
Important!
The vehicle doors lock if key is in
steering lock position 2 and the left
front wheel is rotated. Do not leave key
in steering lock while changing a
wheel.
1. Set parking brake and turn on
hazard warning flasher.
2. Move selector lever to position "P",
turn off engine, and remove key
from steering lock.
3. Prevent vehicle from rolling away
by blocking wheels with wheel
chocks (not supplied with vehicle)
or sizable wood block or stone.
When changing a wheel on a hill,
place chocks on the downhill side
blocking both wheels 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.
4. Using the wrench, loosen but do not
yet remove the wheel bolts.
5. Open jack enough to still fit under
vehicle.
The jack take-up brackets are
located directly behind the front
wheel housings and in front of the
rear wheel housings.
6. Place jack on firm ground. Position
the jack under the take-up bracket so
that it is always vertical (plumb-line)
as seen from the side, even if the
vehicle is parked on an incline.
7. Open jack further until jack arm
end seats firmly in the take-up
bracket and its base sits sqarely on
the ground. Jack up the vehicle until
the wheel is clear of the ground.
Never start engine while vehicle is
raised.
