2011 MERCEDES-BENZ C-CLASS COUPE snow chains

Only winter tyres bearing the
isnowflake
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 ®
to
function optimally in winter, as these tyres
have been designed specificallyf or driving on
snow.
Use M+S tyres of the same make and tread
on all wheels to maintain safe handling char-
acteristics. G
WARNING
M+S tyres with a tread depth of less than
4mmm ust 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.
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 (Y page 176).
When you have fitted the M+S tyres:
X Check the tyre pressures (Y page 339).
X Restart the tyre pressure loss warning sys-
tem (Y page 340). G
WARNING
If you fit the spare wheel when driving with M
+S tyres, bear in mind that driving stability will
be impaired due to unstable cornering char-
acteristics caused by the different 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 aMercedes-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. Snow chains
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 it is not permissible to attach snow chains
to all wheel-tyre combinations; see the
information under "Wheel/tyre combina-
tions" in the "Wheels and tyres" section.
R snow chains must not be fitted to emer-
gency spare wheels, e.g. a "Minispare"
emergency spare wheel.
R fit snow chains only in pairs and only to the
rear wheels. Observe the manufacturer's
installation instructions.
! 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.
Do not exceed the maximum permissible
speed of 50 km/h.
i You may wish to deactivate ESP ®
(Y page 67) when pulling away with snow
chains fitted. This way you can allow the
wheels to spin in a controlled manner, ach-
ieving an increased driving force (cutting
action). 338
Winter operationWheels and tyres

is kept open continuously, which may lead to
air loss.

WARNING
Should the tyre pressure drop repeatedly:
R chec kthe tyre for foreign bodies.
R check whether the wheel is losing air or the
valve is leaking.
R make sure that only a valve cap approved
by Mercedes-Benz is fitted on the tyre
valve.
Tyre pressures that are too low have a nega-
tive effect on vehicle safety, which could lead
you to cause an accident.
If possible, only correct tyre pressures when
the tyres are cold. The tyres are cold when
the vehicle has been parked for at least three
hours or has been driven less than 1.5 km.
Depending on the ambient temperature, the
speed you are driving at and the load on the
tyres, the tyre temperature and thus the tyre
pressure may change by approximately
10 kPa (0.1 bar/1.5 psi) per 10 †. Take this
into account when checking the pressure of
warm tyres and only correct it if it is too low
for the current operating conditions.
Driving with tyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R cause increased tyre damage
R have a negative effect on handling charac-
teristics and thus the driving safety (e.g. by
causing aquaplaning)
i The tyre pressure values given for low
loads are minimum values which offer you
good ride comfort characteristics.
However, you can also use the values given
for higher loads. These are permissible and
will not adversely affect the running of the
vehicle. H
Environmental note
Check the tyre pressure regularly, at least
every 14 days. Tyre pressure loss warning system
Important safety notes While the vehicle is in motion, the tyre pres-
sure loss warning system monitors the set
tyre pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in a tyre. If the speed
of rotation of a wheel changes as a result of
a loss of pressure, a corresponding warning
message will appearint
he multifunction dis-
play. G
WARNING
The tyre pressure loss warning system does
not warn you of an incorrectly set tyre pres-
sure. The table on the inside of the fuel filler
flap will help you decide whether the tyre
pressures should be corrected.
The tyre pressure loss warning system does
not replace the need to regularly check your
vehicle's tyre pressures, since an even loss of
pressure on several tyres at the same time
cannot be detected by the tyre pressure loss
warning system.
The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tyre is penetrated by a foreign object.
In the event of a sudden loss of pressure, bring
the vehicle to a halt by braking carefully. Do
not make any sudden steering movements
when doing so.
The function of the tyre pressure loss warning
system is limited or delayed if:
R snow chains are fitted to your vehicle's
tyres.
R road conditions are wintry.
R you are driving on sand or gravel.
R you adopt a very sporty driving style (cor-
nering at high speeds or driving with high
rates of acceleration).
R you are towing a very heavy or large trailer.
R you are driving with a heavy load (in the
vehicle or on the roof). 340
