M+S tires

G

WARNING

M+S tires with a tire tread depth of less than

ã in (4 mm) are not suitable for use in winter

and do not provide sufficient traction. There is

a risk of an accident.
M+S tires with a tread depth of less than ã in

(4 mm) must be replaced immediately.

At temperatures below 45 ‡ (+7 †), use win-

ter tires or all-season tires. Both types of tire

are identified by the M+S marking.
Only winter tires bearing the i snowflake

symbol in addition to the M+S marking pro-

vide the best possible grip in wintry road con-

ditions. Only these tires will allow driving

safety systems such as ABS and ESP

®

to

function optimally in winter. These tires have

been developed specifically for driving in

snow.
Use M+S tires 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 tires you have

mounted.
When you have mounted M+S tires:

X

Check the tire pressures (

Y

page 309).

X

Restart the tire pressure monitor

(

Y

page 309).

For more information on driving with the

emergency spare wheel, see (

page 338).

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 a risk 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".

!

Vehicles with steel wheels: if you

mount snow chains on steel wheels, you

may damage the hub caps. Remove the hub

caps from the relevant wheels before

mounting the 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, or are of a corresponding

standard of quality.
If you intend to mount snow chains, please

bear the following points in mind:

R

Snow chains may not be mounted on all

wheel/tire combinations. Permissible

wheel-tire combinations (

Y

page 329).

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 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 mount snow chains.

R

Do not exceed the maximum permissible

speed of 30 mph (50 km/h).

i

You may wish to deactivate ESP

®

(

Y

page 66) when pulling away with snow

chains installed. You can thereby allow the

wheels to spin in a controlled manner, ach-

ieving an increased driving force (cutting

action).

emergency spare wheel, see (
