Mercedes-Benz B-Class Electric Drive W245 Operator's Manual page 303

Only position the jack at the appropriate jack-
ing point of the vehicle. The base of the jack
must be positioned vertically, directly under
the jacking point of the vehicle.
! Position a suitable jack correctly on the
intended jacking points. If you fail to posi-
tion the jack correctly, the vehicle may be
damaged.
The jacking points are recesses in the lower
door sill. They can only be seen from under-
neath. There is one located behind each of
the front wheel arches and in front of the
rear wheel arches.
Position the jack in the jacking points so
that when viewed from the side, the jack is
in the vertical position.
! Position a suitable jack only on the jack-
ing points intended for this purpose.
Never position the jack on the high-voltage
battery. Do not jack up the vehicle on the
high-voltage battery. There is otherwise a
risk of damaging the high-voltage battery.
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 is not suited for per-
forming maintenance work under the vehi-
cle.
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.
Changing a wheel
the jack must be placed on a firm, flat and
R
non-slip surface. On a loose surface, a
large, 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).
do not place your hands or feet under the
R
raised vehicle.
do not lie under the vehicle.
R
do not start the electric motor when the
R
vehicle is raised.
do not open or close the doors or the tail-
R
gate when the vehicle is raised.
make sure that no persons are present in
R
the vehicle when the vehicle is raised.
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.
