WARNING
If you deactivate ESP ®
, ESP ®
no longer sta-
bilises the vehicle. There is an increased risk
of skidding and an accident.
Only deactivate ESP ®
in the situations descri-
bed in the following.
It may be best to deactivate ESP ®
in the fol-
lowing situations:
R when using snow chains
R in deep snow
R on sand or gravel

M+S tyres with a tread depth of less than
4 mm must be replaced.
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 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. These tyres have
been developed specifically for driving in
snow.
Use M+S tyres of the same make and tread on
all wheels to maintain safe handling charac-
teristics.
Always observe the maximum permissible
speed specified for the M+S tyres you have
fitted.
If you fit M+S tyres that have a lower maxi-
mum 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.
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 177).
When you have fitted the M+S tyres:
X Check the tyre pressures (Y page 330).
X Restart the tyre pressure loss warning sys-
tem (Y page 331).
X Restart the tyre pressure monitor
(Y page 334).
Information about driving with an emergency spare wheel (Y page 349). 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 fit
snow chains on steel wheels, you may dam-
age the hub caps. Remove the hub caps
from the relevant wheels before fitting the
snow chains.
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that
have been specifically approved for your vehi- cle 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 340).
R only use snow chains 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 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 192).
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, ach-
ieving an increased driving force (cutting
action).

pressure can be checked using the on-board
computer.
If possible, only correct tyre pressures when
the tyres are cold.
The tyres are cold:
R if the vehicle has been parked with the tyres
out of direct sunlight for at least three
hours and
R if the vehicle has not been driven further
than 1.6 km
Depending on the ambient temperature, the
speed at which you are driving and the load on the tyres, the tyre temperature and thus the
tyre pressure changes by approximately
10 kPa (0.1 bar/1.5 psi) per 10 †. Take this
into account when checking the pressure of
warm tyres. Only correct the tyre pressure if it
is too low for the current operating condi-
tions.
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 driving safety (e.g. aqua-
planing)
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 andwill not adversely affect the running of the
vehicle. Tyre pressure loss warning system
General 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 aloss of pressure, a corresponding warning message will appear in the multifunction dis-
play.
You can recognise the tyre pressure loss
warning in the multifunction display in the
Service
Service menu, by the Run Flat Indica‐ Run Flat Indica‐
tor active Restart with OK
tor active Restart with OK message.
Further information on the message display
can be found under "Restarting the tyre pres- sure loss warning system" (Y page 332).
Important safety notes The tyre pressure warning system does not
warn you of an incorrectly set tyre pressure.
Observe the notes on the recommended tyre pressure (Y page 330).
The tyre pressure loss warning does not
replace the need to regularly check the tyre
pressures. An even loss of pressure on sev-
eral tyres at the same time cannot be detec-
ted 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. Avoid
abrupt steering manoeuvres.
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). Tyre pressure
