When you have fitted the M+S tyres:
X
Check the tyre pressures (
Y
page 345).
X
Restart the tyre pressure loss warning system
(
Y

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.
For safety reasons, Mercedes-Benz recom-
mends that you use only 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.
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, observe the notes on the per-
missible wheel/tyre combinations
(
Y
page 355).
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
on vehicles with AIRMATIC, you must always
drive at a raised vehicle level if snow chains
have been fitted (
Y
page 182)
R
when snow chains are fitted, never use Active
Parking Assist (

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.
