Only winter tyres bearing the
isnowflake
symbol in addition to the M+S marking pro-
vide the best possibleg rip in wintry road con-
ditions. Only these tyres will allowd riving
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 atread 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 alower 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 aq ualified specialist workshop, e.g. at a
Mercedes-Ben zService 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 183).
When you have fitted the M+S tyres:
X Check the tyre pressures (Y page 321).
X Restart the tyre pressure loss warning sys-
tem (Y page 322). 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 corneringc har-
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 Centr efor this purpose. In particular,
work relevant to safety or on safety-related
systems must be carried out at aqualified
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 ,orthat are of acorre-
spondin gstandard of quality.
If you inten dtofit snow chains, please bear
the following point sinmind:
R it is not permissible to attac hsnow 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-
genc yspare 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 64) when pulling away with snow
chains fitted. This way you can allow the
wheels to spin in acontrolled manner, ach-
ieving an increased driving force (cutting
action). 320

Engine oil selection is based on the respective
outside temperatures and in accordance with
the SAE classification (viscosity). The table
below shows you which SAE classifications
are to be used. The low-temperature proper-
ties of engine oils can be significantly
impaired during operation due to, for exam-
ple, ageing or soot and fuel accretion. It is
therefore strongly recommended to observe
regularo il changes using an approved engine
oil with the appropriate SA Eclassification. Brake fluid
G
WARNING
The brak efluid constantly absorb smoisture
fro mt he air; this lowers its boiling point.
If the boiling point of the brake fluid is too low,
vapour pockets may form in the brake system
when the brakes are applied hard (e.g. when
driving downhill). This would impair braking
efficiency.
You should have the brake fluid renewed at
regular intervals. The brake fluid change inter-
vals can be found in the Service Booklet.
Only use brake fluid approved by Mercedes-
Benz.I nformation about approved brake flu-
ids can be obtained from any Mercedes-Benz
Service Centre.
