do not drive with aflat tire. Immediately
replace the flat tire with your spare wheel, or
consult aqualified specialist workshop.
Accessories that are not approved for your
vehicle by Mercedes-Benz or that are not being used correctly can impair the operating
safety.
Before purchasin gand using non-approved
accessories, visit aqualified specialist work-
shop and inquire about:
R suitability

Information on driving
R If the vehicle is heavily loaded, chec kthe
tire pressures and correct them if neces-
sary.
R While driving, pay attention to vibrations,
noises and unusual handling characteris-
tics, e.g. pulling to one side. This may indi- cate that the wheels or tires are damaged.If you suspect that atire is defective,
reduce your speed immediately. Stop the
vehicle as soon as possible to chec kthe
wheels and tires for damage. Hidden tire
damage could also be causing the unusual
handling characteristics. If you find no
signs of damage, have the wheels and tires checked at aqualified specialist workshop.
R When parkin gyour vehicle, make sure that
the tires do not get deformed by the curb or
other obstacles. If it is necessary to drive
over curbs, speed humps or similar eleva- 250

General notes

Observe the notes in the "Changing awheel"
section (Y page 270). Drivin
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.

The tire pressure table contains the recom-
mended pressures for col dtiresfor various
