assists the driver when pulling away on
wet or slippery roads. ESP ®
can also stabilise
the vehicle during braking.
ETS (Electronic Traction System) i
Observe the "Important safety notes" sec-
tion (Y page 54).
ETS traction control is part of ESP ®
.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. In addition, more drive torque is transfer-
red to the wheel or wheels with traction.
Traction control remains active if you deactivate
ESP ®
.

information regarding tyres at specialist tyre
retailers, at qualified specialist workshops or at any Mercedes-Benz Service Centre.
R Only fit tyres and wheels of the same type and
make.
Exception: it is permissible to fit a different
type or make in the event of a flat tyre.
R Only fit tyres of the correct size onto the
wheels.
R Run in new tyres at moderate speeds for the
first 100 km. They only reach their full per-
formance after this distance.
R Do not drive with tyres which have too little
tread depth. This otherwise significantly
reduces the traction on wet roads (aquaplan-
ing).
R Replace the tyres after six years at the latest,
regardless of wear.
Observe the notes on the emergency spare
wheel (Y page 273). Winter operation
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 (Y page 267). Driving with summer tyres
At temperatures below +7 †, summer tyres lose
elasticity and therefore traction and braking
power. Change the tyres on your vehicle to
M+S tyres. Using summer tyres at very cold
temperatures could cause tears to form,
thereby damaging the tyres permanently.
Mercedes-Benz cannot accept responsibility for
this type of damage. G
WARNING
Damaged tyres can cause tyre inflation pres-
sure loss. As a result, you could lose control of your vehicle. There is a risk of accident.
Check the tyres regularly for signs of damageand replace any damaged tyres immediately. M+S tyres
G
WARNING
M+S tyres with a tyre tread depth of less than 4 mm are not suitable for use in winter as they
do not provide sufficient traction. There is a
risk of accident.
M+S tyres with a tread depth of less than
4 mm must be replaced.
At temperatures below +7 †, use winter tyres or all-season tyres. Both types of tyre are identified
by the M+S marking.
Only winter tyres bearing the isnowflake
symbol in addition to the M+S marking provide
the best possible grip in wintry road conditions. Only these tyres will allow driving safety sys-
tems such as ABS and ESP ®
to function opti-
mally in winter. These tyres have been devel-
oped specifically for driving in snow.
Use M+S tyres of the same make and tread on all
wheels to maintain safe handling characteris-
tics.
Always observe the maximum permissible
speed specified for the M+S tyres you have fit-
ted.
If you fit M+S tyre sthat have a lower maximum
permissible speed than that of the vehicle, affix
an appropriate warning label in the driver's field
of vision. This can be obtained at a qualified
specialist workshop.
Under these circumstances, you should also
restrict the maximum design speed of the vehi- cle using permanent SPEEDTRONIC so that it
does not exceed the maximum permissible
speed for the M+S tyres (Y page 130).
When you have fitted the M+S tyres:
X Check the tyre pressures (Y page 264).
X Restart the tyre pressure monitor
(Y page 267).

WARNING
If you have fitted snow chains to the front
wheels, they may scrape against the vehicle
body or chassis components. This could Winter operation
263Wheels and tyres
Z
cause damage to the vehicle or the tyres.
There is a risk of an accident.
To avoid hazardous situations:
R never fit snow chains on the front wheels
R fit snow chains to the rear wheels in pairs.
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that have been specifically approved for your vehicle by
Mercedes-Benz, or that are of a corresponding
standard of quality. For more information,
please contact a qualified specialist workshop.
If you intend to fit snow chains, please bear the
following points in mind:
R snow chains cannot be fitted to all wheel-tyre
combinations. Permissible wheel-tyre combi-
nations (Y page 272).
R only use snow chains if the road surface is
completely snow-covered. Remove the snow
chains as soon as possible when you come to
a road that is not snow-covered.
R local regulations may restrict the use of snow
chains. Observe the appropriate regulations if you wish to fit snow chains.
R do not exceed the maximum permissible
speed of 50 km/h.
When pulling away with snow chains fitted, you can deactivate ESP ®
(Y page 58). This way you
can allow the wheels to spin in a controlled
manner, achieving increased driving force (cut-
ting action).

spare wheel (Y page 273). Tyre pressure
Tyre pressure specifications
G
WARNING
Underinflated or overinflated tyres pose the
following risks:
R the tyres may burst, especially as the load
and vehicle speed increase.
R the tyres may wear excessively and/or
unevenly, which may greatly impair tyre
traction.
R the driving characteristics, as well as steer-
ing and braking, may be greatly impaired. There is a risk of an accident.
Observe the recommended tyre pressure and
check the tyre pressure of all the tyres includ-
ing the spare wheel:
R at least every two weeks
R when the load changes
R before embarking on a longer journey
R for changed operating conditions, e.g. off-
road driving
If necessary, correct the tyre pressure. G
WARNING
If you fit unsuitable accessories onto tyre
valves, the tyre valves may be overloaded and malfunction, which can cause tyre pressure
loss. Due to their design, retrofitted tyre pres-
sure monitors keep the tyre valve open. This
can also result in tyre pressure loss. There is a risk of accident.
Only screw standard valve caps or valve caps
specifically provided by Mercedes-Benz for
your vehicle onto the tyre valve. G
WARNING
If the tyre pressure drops repeatedly, the
wheel, valve or tyre may be damaged. Tyre
pressure that is too low may result in a tyre
blow-out. There is a risk of accident.
R Check the tyre for foreign objects.
R Check whether the wheel is losing air or the
valve is leaking.
If you are unable to rectify the damage, con-
tact a qualified specialist workshop. H
Environmental note
Check the tyre pressure regularly, at least
every 14 days.
The recommended tyre pressures for various
operating conditions can be found in the tyre
pressure table on the fuel filler flap
(Y page 118).
