Changing a wheel/fitting the emer-
gency spare wheel*
G Risk of accident
The wheel dimensions and tyre size of the
emergency spare wheel* may differ from
those of the standard wheels.
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 emergency spare wheel*
replaced as soon as possible at a qualified
specialist workshop which has the neces-
sary specialist knowledge and tools to carry
out the work required. Mercedes-Benz rec-
ommends that you use a Mercedes-Benz
Service Centre for this purpose. In particu-
lar, work relevant to safety or on safety-
* optional
related systems must be carried out at a
qualified specialist workshop.
