Mercedes-Benz C-Class 2014 Owner's Manual page 443

Changing a wheel
440
must be positioned vertically, directly under
the jacking point of the vehicle.
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 the jack is
used incorrectly, it could tip over while the
vehicle is 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 suitable 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 positioning wheel chocks. Do not
release 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 tyres and the ground does
not exceed 3 cm.
never place your hands or feet under the
R
raised vehicle.
do not lie under the vehicle.
R
do not start the engine when the vehicle is
R
raised.
do not open or close a door or the boot lid
R
when the vehicle is raised.
make sure that no persons are present in
R
the vehicle when the vehicle is raised.

trim: the wheel trim covers the wheel bolts.
