gwiths ummer tires
At temperatures below 45 ‡(+7† ), summer
tires experience aconsiderable loss in elas-
ticity and therefore traction and braking
power. Change the tires on you rvehicle to
M+S tires. Using summe rtires at very cold
temperatures coul dcause cracks to form,
thereb ydamaging the tires permanently.
Mercedes-Benz cannot accep tresponsibility
for this type of damage. M+S tires
G
WARNING
M+S tires with atire tread depth of less than
00CF in (4 mm )are not suitabl efor use in winter
and do not provide sufficient traction. There is
ar isk of an accident.
M+S tires with atread depth of less than 00CFin
(4 mm) must be replaced immediately.
At temperatures below 45 ‡(+7† ), use win-
ter tires or all-season tires. Both type softire
are identified by the M+S marking.
Only winter tires bearing the 004Dsnowflake
symbol in addition to the M+S marking pro-
vide the best possibl egrip in wintry road con-
ditions. Only these tires will allow driving
safety systems such as ABS and ESP ®
to
function optimally in winter. Thi sisbecause
these tires were specifically developed for
driving in snow.
Use M+S tires of the same make and tread on
allw heels to maintain safe handling charac-
teristics.
Always observe the maximu mpermissible
spee dspecified for the M+S tires you have
mounted.
When you have mounted the M+S tires:
X Check the tire pressure s(Ypag e253).
X Restart the tire pressure monitor
(Y pag e259). 252

Snow chains
G
WARNING
If snow chains are installed to the front
wheels, they may drag against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tires.
There is arisk of an accident.
To avoid hazardous situations:
R never install snow chains to the front
wheels
R always install snow chains in pairs to the
rear wheels.
! On some tire sizes there is not enough
space for snow chains. To avoid damage to
the vehicle or tires, observe the "Wheel and tire combinations" section under "Tires and
wheels".
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 are of acorresponding
standard of quality.
R You may not attach snow chains to all
wheel-tire combination ,see the informa-
tion under "Wheels and tires" in the "Tech-
nical data" section.
R Only use snow chains when driving on
roads completely covered by snow.
Remove the snow chains as soon as possi- ble when you come to aroad that is not
snow-covered.
R Local regulations may restrictt he use of
snow chains. Observe the appropriate reg- ulations if you wish to mount snow chains.
R Do not exceed the maximum permissible
speed of 30 mph (50 km/h).
i You can deactivate ESP ®
(Y page 55)
when pulling away with snow chains instal-
led. You can thereby allow the wheels to
spin in acontrolled manner, achieving an
increased driving force (cuttinga ction). Tire pressure

Important safety notes G
WARNING
Underinflated or overinflated tires pose the
following risks:
R the tires may burst, especially as the load
and vehicle speed increase.
R the tires may wear excessively and/or
unevenly, which may greatly impair tire
traction.
R the driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is arisk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires includ-
ing the spare wheel:
R monthly, at least
R if the load changes
R before beginning along journey
R under different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.
i The specifications on the sample Tire and
Loading Information placard and tire pres-
sure tables are examples. Tire pressure
specifications are vehicle-specific and may
deviate from the data shown here. The tire pressure specifications that are valid for
your vehicle can be found on the Tire and
Loading Information placard and tire pres-
sure table on the vehicle.
General notes The recommended tire pressures for the tires
mounted at the factory can be found on the
labels described here.
Further information on tire pressures can be
obtained at aqualified specialist workshop. Tire pressure
253Wheels and tires Z

If the tire pressure is not set correctly, this
can leadtoane xcessive build up of heat and
as udden loss of pressure.
For more information, contact aqualified spe-
cialist workshop. Important notes on tire pressure
G
WARNING
If the tire pressure drops repeatedly,t he
wheel, valve or tire may be damaged. Tire
pressure that is too low may resultina tire
blow-out. There is arisk of an accident.
R Check the tire for foreign objects.
R Check whether the wheelisl osing air or the
valve is leaking.
If you are unabletor ectify the damage, con-
tact aqualifieds pecialist workshop. G
WARNING
If you fit unsuitable accessorie sonto tire
valves ,the tire valves may be overloaded and
malfunction, which can cause tire pressure
loss. Due to their design, retrofitted tire pres- sure monitors keep the tire valve open. This
can also resultint ire pressure loss. There is a
risk of an accident.
Only screw the standard valve cap or other
valve caps approved by Mercedes-Benz for
yourv ehicle onto the tire valve.
Use asuitable pressure gauge to check the
tire pressure. The outer appearance of atire
does not permit any reliable conclusion about the tire pressure. On vehicle sequippedw ith
the electronic tire pressure monitor, the tire
pressure can be checked in the on-board
computer.
The tire temperature and pressure increase
when the vehicle is in motion. This is depend-
ent on the driving speed and the load.
Therefore ,you shouldo nly correct tire pres-
sures when the tires are cold. The tires are cold:
R if the vehicle has been parked without
direct sunlight on the tires for at least three
hours and
R if the vehicle has not been driven further
than 1mile (1.6 km)
The tire temperature changes depending on
the outsid etemperature ,the vehicle speed
and the tire load. If the tire temperature
changes by 18 ‡(10 †), the tire pressure
changes by approximately 10 kPa (0.1 bar/
1.5 psi).T ake this into account when check-
ing the pressure of warm tires. Only correct
the tire pressure if it is too low for the current
operating conditions. If you check the tire
pressure when the tires are warm, the result- ing valuew illbeh igherthan if the tires were
cold. This is normal. Do not reduce the tire
pressure to the values pecified for cold tires.
The tire pressure would otherwis ebetoo low.
Observe the recommended tire pressures for
cold tires:
R on the Tire and Loading Information placard
on the B-pilla ronthe driver's side
R in the tire pressure table on the inside of the
fuel filler flap Underinflated or overinflated tires
Underinflated tires G
WARNING
Tires with pressure that is too low can over-
heat and burst as aconsequence. In addition,
they also suffer from excessive and/or irreg-
ularw ear, which can severel yimpair the brak-
ing propertie sand the driving characteristics.
There is arisk of an accident.
Avoid tire pressures that are too low in all the
tires, including the spare wheel.
Underinflated tires may:
R overheat, leading to tire defects
R adversely affect handling Tire pressure
