You may wish to deactivate

ESP ( page 48) when pulling away with
Y
snow chains fitted. This way you can allow
the wheels to spin in a controlled manner,
achieving an increased driving force (cut-
ting action).
M+S tyres
G
WARNING
M+S tyres with a tread depth of less than
4 mm must be replaced. They are no longer
suitable for winter use and can no longer pro-
vide sufficient grip. This could cause you to
lose control of your vehicle and cause an acci-
dent.
G WARNING
If you fit the emergency spare wheel when
driving with M+S tyres, bear in mind that driv-
ing stability will be impaired due to unstable
cornering characteristics caused by the dif-
ferent tyres. You should therefore adapt your
driving style and drive carefully.
Have the spare wheel replaced at the nearest
qualified specialist workshop which has the
necessary specialist knowledge and tools to
carry out the work required. Mercedes-Benz
recommends that you use a Mercedes-Benz
Service Centre for this purpose. In particular,
work relevant to safety or on safety-related
systems must be carried out at a qualified
specialist workshop.
At temperatures below +7 †, use winter tyres
or all-season tyres. Both types of tyre are
identified by the M+S marking.
Only winter tyres bearing the i snowflake
symbol in addition to the M+S marking pro-
vide the best possible grip in wintry road con-
ditions. Only these tyres will allow driving
safety systems such as ABS and ESP
function optimally in winter, as these tyres
have been designed specifically for driving on
snow.
Use M+S tyres of the same make and tread
on all wheels to maintain safe handling char-
acteristics.
Always observe the maximum permissible
speed specified for the M+S tyres you have
fitted.
If you fit M+S tyres which have a lower max-
imum permissible speed than that of the vehi-
cle, affix an appropriate warning sign in the
driver's field of vision. This can be obtained
at a qualified specialist workshop, e.g. at a
Mercedes-Benz Service Centre.
Under these circumstances, you should also
restrict the maximum speed of the vehicle
using permanent SPEEDTRONIC so that it
does not exceed the maximum permissible
speed for the M+S tyres(
When you have fitted the M+S tyres:

Tyre pressure
Recommended tyre pressure
You will find a table of tyre pressures for var-
ious operating conditions on the inside of
your vehicle's fuel filler flap.
Operation with emergency spare wheel:
The applicable value for the emergency spare
wheel is stated on the spare wheel and in the
technical data section.
The table inside the fuel filler flap may state
tyre pressures for different load conditions.
These are defined in the table as different
numbers of passengers and amounts of lug-
gage. The actual number of seats may vary –
for more information please refer to the vehi-
cle's registration documents.
