M+S tyres with
atread depth of less than
4m mm ust 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 sys-
tems such as ABS and ESP ®
to function opti-
mally in winter. These tyres have been devel-
oped 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 alower maxi-
mum permissible speed than that of the vehi-
cle, affix acorresponding warning label in the
driver's field of vision. This can be obtained at aq ualified 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 217).
When you have fitted the M+S tyres:
X Check the tyre pressures (Y page 420).
X Restart the tyre pressure loss warning sys-
tem (Y page 422).
X Restart the tyre pressure monitor
(Y page 424).

gency spare wheel (Y page 465).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
arisk 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.
! 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 fittingt he
snow chains.
For safety reasons, Mercedes-Ben zrecom-
mends that you only use snow chains that
have been specifically approved for your vehi- cle by Mercedes-Benz, or that are of acorre-
sponding standard of quality. For more infor-
mation, please contact aqualified specialist
workshop.
If you intendtof it 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 431).
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 aroad 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 on vehicles with AIRMATIC, you must drive
at raised vehicle level if snow chains have
been fitted (Y page 231).
R when snow chains are fitted, never use
Active Parking Assist (Y page 239).

ressure specifications G
WARNING
Tyres with insufficien torexcessiv etyre pres-
sure harbour the following hazards:
R the tyres may burst, especially as the load
and vehicle speed increase.
R the tyres may wear excessively or unevenly
which can severely impair tyre traction.
R the handling as well as steerin gand braking
characteristics may be severely affected.
There is arisk of an accident.
Observe the recommended tyre pressures
and check the tyre pressure of all the tyres
including the spare wheel:
R every day before starting ajourney
R when the load changes
R prior to long journey
R for changed operating conditions, e.g. off-
road driving
If necessary, correc tthe tyre pressure. G
WARNING
If you fit unsuitable accessories ontot yre
valves, the tyre valves may be overloaded and malfunction, which can cause tyre pressure
loss. Due to their design, retrofitted tyre pres-
sure monitors keep the tyre valve open. This
can also result in tyre pressure loss. There is a risk of accident.
Only screw standard valve caps or valve caps
specifically provided by Mercedes-Benz for
your vehicle ontot he tyre valve. G
WARNING
If the tyre pressure drops repeatedly, the
wheel, valve or tyre may be damaged. Tyre
pressure that is too low may result in atyre
blow-out. There is arisk of accident.
R Check the tyre for foreign objects.
R Check whether the wheel is losing air or the
valve is leaking.
If you are unable to rectify the damage, con-
tact aqualified specialist workshop. H
Environmenta
lnote
Check the tyre pressure regularly, at least
every 14 days.
You will find atable of tyre pressures for var-
ious operating conditions on the tyre pres-
sure label on the inside of your vehicle's fuel
filler flap (Y page 202).
Operation with an emergency spare
wheel: information on operation with an
emergenc yspare wheel can be found in the
general notes in the "Emergency spare wheel" section (Y page 465).
Operation with atrailer: the applicable
value for the rear tyres is the maximum tyre
pressure value stated in the table inside the
fuel filler flap.
The table of tyre pressures may also state tyre
pressures for different load conditions. These are defined in the table as different numbers
of passengers and amounts of luggage. The
actual number of seats may vary; for more
information, please refer to the vehicle's reg- istration documents.
If tyre sizes are not specified, the tyre pres-
sures stated on the tyre pressure information
label apply for all tyres approved for this vehi- cle. 420
Tyrep
ressureWheels and tyres

If
at yre size precedes atyre pressure, the
following tyre pressure information is only
validf or that tyre size.
Use asuitable pressure gauge to check the
tyre pressure. The outer appearance of atyre
does not permit any reliable conclusion about the tyre pressure. On vehicle sfitted with the
electronic tyre pressure monitor, the tyre
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
vehicle speed and the loadont he tyres, the
tyre temperature and thus the tyre pressure
changes by approximately 10 kPa (0. 1bar/
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 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 anegative effect on handling charac-
teristics and thus driving safety (e.g. aqua-
planing) 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 higherl oads. These are permissible and
willn ot adversely affect the running of the
vehicle.
Speeds up to 210 km/h: despite the values
stated on the tyre pressure information label (fuel filler flap), for speedsupt o210 km/h
and with R16 tyres, the values stated can be
reduced as follows, withou tareduction in
safety:
R Saloon: Ò30 kPa (Ò0.3 bar/Ò4p si)
R Estate: Ò20 kPa (Ò0.2 bar/Ò3p si)
This does not apply to vehicle stowing a
trailer.
This improves the ride comfort of yourv ehi-
cle; however, fuel consumption may increase slightly. Tyre pressure lossw
arning system
General notes Whilet
he 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 atyre. If the speed
