When you have fitted the M+S tyres:
X
Check the tyre pressures (
Y
page 364).
X
Restart the tyre pressure monitor
(
Y
page 368).
X
Restart the tyre pressure loss warning system
(
Y
page 366).

Snow chains
G
WARNING
If you have fitted snow chains to the front
wheels, they may scrape against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tyres.
There is a risk of an accident.
To avoid hazardous situations:
R
never fit snow chains on the front wheels
R
fit snow chains to the rear wheels in pairs.
!
You must drive at a raised vehicle level if
snow chains have been fitted. The vehicle
could otherwise be damaged. Observe the
notes in the "AIRMATIC package" section.
!
When driving with snow chains fitted, do not
use the ADS sport mode (Adaptive Damping
System). The vehicle could otherwise be dam-
aged.
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that have
been approved for Mercedes-Benz or that are of
an equivalent standard of quality. For more
information, please contact a qualified special-
ist workshop.
Fit the snow chains on all driven wheels for max-
imum tractive power and driving stability. If you
own snow chains for two driven wheels only, fit
the snow chains to the wheels on the rear axle.
The vehicle then remains more stable under
braking.
If you wish to fit snow chains, please bear the
following points in mind:
R
snow chains cannot be fitted to all wheel/tyre
combinations. Permitted wheel/tyre combi-
nations (
Y
page 374).
R
use snow chains only if the road surface is
completely snow-covered. Remove the snow
chains as soon as possible when you come to
a road that is not snow-covered.
R
local regulations may restrict the use of snow
chains. Observe the appropriate regulations if
you wish to fit snow chains.
R
do not exceed the maximum permissible
speed of 50 km/h.
R
never use Parking Pilot when snow chains are
fitted (
Y
page 204).
You may wish to deactivate ESP
®
when pulling
away with snow chains fitted (
Y
page 73). This
allows the wheels to spin in a controlled manner,
achieving increased propulsive force (cut).

Tyre pressure
Tyre pressure specifications
G
WARNING
Underinflated or overinflated tyres pose the
following risks:
R
the tyres may burst, especially as the load
and vehicle speed increase.
R
the tyres may wear excessively and/or
unevenly, which may greatly impair tyre
traction.
R
the driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is a risk of an accident.
Observe the recommended tyre pressure and
check the tyre pressure of all the tyres includ-
ing the spare wheel:
R
at least every two weeks
R
when the load changes
R
before embarking on a longer journey
R
for changed operating conditions, e.g. off-
road driving
If necessary, correct the tyre pressure.
G
WARNING
If you fit unsuitable accessories onto tyre
valves, the tyre valves may be overloaded and
malfunction, which can cause tyre pressure
loss. Due to their design, retrofitted tyre pres-
