327Changing a wheel/fitting the emer-
gency spare wheel*
G
Risk of accident
The wheel dimensions and tyre size of the
spare wheel*, the emergency spare
wheel* and standard wheels may differ
from one another.
The handling characteristics of your vehicle
will change if you fit an emergency spare
wheel*. Adapt your style of driving accord-
ingly.
You may only use the emergency spare
wheel* for a short while. Do not exceed the
maximum speed of 80 km/h and do not
deactivate ESP ®
.
Never drive the vehicle with more than one
emergency spare wheel* fitted. 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 323).
X If a trailer is coupled, uncouple it.
X Position the wheels in the straight-ahead
position.
X Take the following from the stowage well
beneath the luggage compartment floor:
R
the wheel wrench
R the wheel chock
R the jack
X Secure the vehicle to prevent it from rolling
away.
On level ground: place chocks or similar
items under the front and rear of the wheel
that is diagonally opposite the wheel you
wish to change. Securing a vehicle on level ground (example illus-
tration)
X
On downhill gradients: place chocks or
similar items under both wheels of the
other axle. Securing a vehicle on slight downhill slopes (exam-
ple illustration) Practical advice
