Mercedes-Benz 2013 CLA, Owner'S Manual

Page: 321 / 352

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(
Y
page 173).
When you have fitted the M+S tyres:
X
Check the tyre pressures (
Y
page 319).
X
Restart the tyre pressure loss warning sys-
tem (
Y
page 321).
For more information on driving with the
emergency spare wheel, see (

Snow chains
G
WARNING
If snow chains are fitted to the rear wheels,
they may scrape against the vehicle body or
chassis components. This could cause dam-
age to the vehicle or the tyres. There is a risk
of an accident.
To avoid hazardous situations:
R
never fit snow chains on the rear wheels
R
always fit snow chains in pairs to the front
wheels.
! Vehicles with steel wheels: if you wish
to fit snow chains to steel wheels, make
sure that you remove the respective
wheels' hubcaps first. The hubcaps may
otherwise be damaged.
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that
have been specially approved for your vehicle
by Mercedes-Benz, or that are of a corre-
sponding standard of quality.
If you intend to fit snow chains, please bear
the following points in mind:
R
snow chains cannot be fitted to all wheel-
tyre combinations. Permissible wheel-tyre
combinations (
Y
page 329).
R
only use snow chains when the road sur-
face is completely snow-covered. Remove
the snow chains as soon as possible when
you come to a road that is not snow-cov-
ered.
R
local regulations may restrict the use of
snow chains. Observe the appropriate reg-
ulations if you wish to fit snow chains.
R
do not exceed the maximum permissible
speed of 50 km/h.
R
when snow chains are fitted, never use
Active Parking Assist (
Y
page 186).
i You may wish to deactivate
ESP
®
(
Y
page 68) when pulling away with
snow chains fitted. This way you can allow
the wheels to spin in a controlled manner,
achieving an increased driving force (cut-
ting action).
For more information on driving with the
emergency spare wheel, see (
Y

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.
