Mercedes-Benz B-Class Electric Drive Operator's Manual page 327

Also observe the notes in the "Changing a
wheel" section.
Observe the following when raising the
vehicle:
To raise the vehicle, only use the vehicle-
R
specific jack that has been tested and
approved by Mercedes-Benz. If used incor-
rectly, the jack could tip over with the vehi-
cle raised.
The jack is designed only to raise and hold
R
the vehicle for a short time while a wheel
is being changed. It must not be used for
performing maintenance work under the
vehicle.
Avoid changing the wheel on uphill and
R
downhill slopes.
Before raising the vehicle, secure it from
R
rolling away by applying the parking brake
and inserting wheel chocks. Do not disen-
gage the parking brake while the vehicle is
raised.
The jack must be placed on a firm, flat and
R
non-slip surface. On a loose surface, a
large, flat, load-bearing underlay must be
used. On a slippery surface, a non-slip
underlay must be used, e.g. rubber mats.
Do not use wooden blocks or similar
R
objects as a jack underlay. Otherwise, the
jack will not be able to achieve its load-
bearing capacity due to the restricted
height.
Make sure that the distance between the
R
underside of the tires and the ground does
not exceed 1.2 in (3 cm).
Never place your hands and feet under the
R
raised vehicle.
Do not lie under the vehicle.
R
Do not start the drive system when the
R
vehicle is raised.
Never open or close a door or the tailgate
R
when the vehicle is raised.
Make sure that no persons are present in
R
the vehicle when the vehicle is raised.
Changing a wheel
Using lug wrench :, loosen the bolts on
X
the wheel you wish to change by about one
full turn. Do not unscrew the bolts com-
pletely.
Jacking points
The jacking points are located just behind the
front wheel housings and just in front of the
rear wheel housings (arrows).
Take ratchet wrench ? out of the vehicle
X
tool kit and place it on the hexagon nut of
jack = so that the letters AUF are visible.
Position jack = at jacking point ;.
