approximately á in (1.6 mm). If this is the
case, the tire is so worn that it must be
replaced.
Selecting, mounting and replacing
tires
Only mount tires and wheels of the same
R
type and make.
Exception: it is permissible to install a dif-
ferent type or make in the event of a flat
tire. Observe the "Tires with run-flat char-
acteristics" section (
Only mount tires of the correct size onto
R
the wheels.
Break in new tires at moderate speeds for
R
the first 60 miles (100 km). The tires only
reach their full performance after this dis-
tance.
Do not drive with tires which have too little
R
tread depth, as this significantly reduces
the traction on wet roads (hydroplaning).
Replace the tires after six years at the lat-
R
est, regardless of wear.

General notes
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section ( page 299).

Driving with summer tires
At temperatures below 45 ‡ (+7 †), summer
tires lose elasticity and therefore traction and
braking power. Change the tires on your vehi-
cle to M+S tires. Using summer tires at very
cold temperatures could cause cracks to
form, thereby damaging the tires perma-
nently. Mercedes-Benz cannot accept
responsibility for this type of damage.

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
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.
Once the winter tires are mounted:
Check the tire pressures (

Snow chains
G WARNING
If snow chains are mounted on the rear
wheels, the snow chains could cause abrasion
to the vehicle body or to chassis components.
This could cause damage to the vehicle or the
tires. There is a risk of an accident.
