259Changing a wheel/fitting the spare
wheel*
G
Risk of accident
The wheel dimensions and tyre size of the
"Minispare" emergency spare wheel* may
differ from those of the standard wheels.
Your vehicle's handling characteristics will
change when a "Minispare" emergency
spare wheel* is fitted. Adapt your style of
driving accordingly.
The "Minispare" emergency spare wheel*
may only be used for a short time. Do not
exceed the maximum speed of 80 km/h
and do not deactivate ESP ®
.
Never drive the vehicle with more than one
"Minispare" emergency spare wheel* fit-
ted. G
Risk of accident
Have the "Minispare" emergency spare
wheel* or the spare wheel* replaced with
a new wheel as soon as possible at a quali-
fied specialist workshop which has the nec-
essary specialist knowledge and tools to
carry out the work required. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centre for this pur- pose. In particular, work relevant to safety
or on safety-related systems must be car-
ried out at a qualified specialist workshop.
Preparing the vehicle X
Prepare the vehicle as described
(Y page 253).
X If a trailer is coupled, uncouple it.
X Place the wheels in the straight-ahead posi-
tion.
X Take the "Minispare" emergency spare
wheel* or the spare wheel* out of the stow-
age well under the luggage compartment
floor.
X Take the following out of the left-hand
stowage compartment in the luggage com-
partment

Wheel wrench
X Using wheel wrench 1, loosen the bolts on
the wheel you wish to change by about one
full turn. Do not unscrew the bolts com-
pletely.
Raising the vehicle G
Risk of injury
The jack is designed only to raise the vehi-
cle for a short time while a wheel is being
changed.
The vehicle must be placed on stands if you
intend to work under it.
Make sure that the jack is placed on a firm,
non-slip, level surface. Do not use wooden
blocks or similar objects as a jack underlay. Otherwise, the jack will not be able to ach-
ieve its load-bearing capacity due to the
restricted height.
Do not start the engine at any time while
the wheel is being changed.
Do not lie under the vehicle when it is being
supported by the jack. If you do not raise
the vehicle as described, it could slip off the
jack (e.g. if the engine is started or a door
or the tailgate is opened or closed) and you
could be seriously injured. G
Risk of accident
If you fail to position the jack correctly, the
vehicle may:
R slip off the jack
R injure you or others
R be damaged
Thus, it is important to make sure that the
jack is positioned correctly in the respec-
tive jacking points. Before positioning the
jack, remove any dirt that may have collec-
ted in the jacking points.
The jacking points for the jack are located
behind the wheel housings of the front wheels
and in front of the wheel housings of the rear
wheels. 1
