i
In wintry driving conditions, always use
winter tyres (M+S tyres) and if necessary,
snow chains. Only in this way will the driv-
ing safety systems described in this section
work as effectively as possible. G
Risk of accident
The risk of an accident is significantly
increased by driving too fast. This is particu-
larly the case when cornering as well as on
wet or slippery roads or when driving too close
to the vehicle in front.
The driving safety systems described in this
section can neither reduce this risk nor over-
ride the laws of physics.
For this reason, always adapt yourd riving
style to the prevailing road and weather con-
ditions. Maintain sufficient distance from
other road users and objects on the road. ABS (Anti-lock Braking System)
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the vehi-
cle when braking.
ABS works from a speed of about 8 km/h
upwards, regardless of road-surface condi-
tions. ABS works on slippery surfaces, even
when you only brake gently. G
Risk of accident
Do not depress the brake pedal several times
in quick succession (pumping) .Depress the
brake firmly and evenly. Pumping the brake
pedal reduces the braking effect.
Braking If ABS intervenes when braking, you will feel
a pulsing in the brake pedal.
X If ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
X To make a full brake application:
depress the brake pedal with full force. G
Risk of accident
If ABS is faulty, the wheels could lock when
braking .This limits the steerability of the vehi-
cle when braking and the braking distance
may increase.
If ABS is deactivated due to a malfunction,
then BAS and ESP are also deactivated. There
is an increased risk of your vehicle skidding in
certain situations.
You should always adapt your driving style to
suit the prevailing road and weather condi-
tions. BAS (Brake Assist)
BAS operates in emergency braking situa-
tions. If you depress the brake pedal quickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance.
X Keep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. G
Risk of accident
If BAS has malfunctioned, the braking system
remains available with full brake boosting
effect. However, braking force is not auto-
matically increased in emergency braking sit-
uations and the stopping distance may
increase. Adaptive brake lamps
i Adaptive brake lamps are only available in
certain countries.
If you brake sharply from a speed of more
than 50 km/h or if braking is assisted by BAS,
the brake lamps flash rapidly.Int his way,
traffic travelling behind you is warned in an
even more noticeable manner.
If you brake sharply from a speed of more
than 70 km/h to a standstill, the hazard warn-
ing lamps are activated automatically .Ifthe 46

brakes are applied again, the brake lamps
light up continuously. The hazard warning
lamps switch off automatically if you travel
faster than 10 km/ h.You can also switch off
the hazard warning lamps using the hazard
warning switch button (Y page 216).ESP
®
(Electronic Stability Program)
You can selec tbetween the three following
states of ESP ®
:
R ESP ®
is activated.
R ESP ®
Sport is activated.
R ESP ®
is deactivated.
ESP ®
is activated as soon as you start the
engine. When ESP ®
Sport is activated, the
0005 warning lamp lights up in the instrument
panel. When ESP ®
is deactivated, the 0001
and 0002 warning lamps light up in the instru-
ment panel.
Characteristics of ESP ®ESP
®
monitors driving stability and traction,
i.e. power transmission between the tyres
and the road surface.
If ESP ®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilise the
vehicle. If necessary, the engine output is also
modified to keep the vehicle on the desired
course within physical limits. ESP ®
assists
the driver when pulling away on wet or slip-
pery roads. ESP ®
can also stabilise the vehi-
cle during braking.
When ESP ®
intervenes, the 0002warning
lamp flashes in the instrument panel. G
Risk of accident
If the 0002 warning lamp in the instrument
cluster flashes, proceed as follows: R
do not deactivate ESP ®
under any circum-
stances
R only depress the accelerator pedal as far as
necessary when pulling away
R adapt your driving style to suit the prevail-
ing road and weather conditions
Otherwise, the vehicle could go into a skid.
ESP ®
cannot reduce the risk of an acciden tif
you drive too fast. ESP ®
cannot override the
laws of physics.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
ESP ®
is activated automatically when the
engine is running .Inthe following situations,
it may be better to activate ESP ®
Sport or
deactivate ESP ®
:
R when using snow chains
R in deep snow
R on sand or gravel G
Risk of accident
Activate ESP ®
as soon as the situations
described above no longer apply.O therwise,
ESP ®
will only be able to stabilise the vehicle
to a limited degree if the vehicle starts to skid
or if a wheel starts to spin.
Characteristics of ESP ®
Sport ESP
®
Sport raises the interventio nthreshold
for stabilising the vehicle. This allows for a
sportier driving style on designated race cir-
cuits and may in certain situations improve
the traction in comparison with ESP ®
.
If you activate ESP ®
Sport:
R ESP ®
only improves driving stability to a
limited degree.
R engine torque is only restricted to a limited
degree and the drive wheels are able to
spin. The spinning wheels produce a cut-
ting effect for better traction. Driving safety systems

wheels which have been approved by
Mercedes-Ben
zspecifically for your vehi-
cle. These tyres have been specially adap-
ted for use with the driving safety systems,
such as ABS or ESP ®
.Ify ou use other tyres
and wheels, Mercedes-Benz cannot accept
any responsibility for damage that may
result from this. Further information about
tyres, wheels and approved combinations
can be obtained from any Mercedes-Benz
Service Centre.
If you use tyres other than those tested and
recommended for Mercedes-Benz vehi-
cles, characteristics such as handling, vehi-
cle noise emissions and fuel consumption
may be adversely affected. In addition, the
wheels may come into contact with the
body or axle components when heavily loa-
ded or when driving with snow chains. This
could result in damage to the tyres or the
vehicle.
! Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As a result,
Mercedes-Benz cannot guarantee vehicle
safety if retreaded tyres are fitted. Do not
fit used tyres if you have no information
about their previous usage. G
Risk of accident
Tyres, wheels or accessories which have not
been approved by Mercedes-Benz for your
vehicle or are not used as they should be, can
impair driving safety. As a result, you could
cause an accident .Before purchasing and
using them, enquire about their suitability,
legal stipulations and factory recommenda-
tions at a Mercedes-Benz Service Centre.
Modification work on the brake system and
wheels is not permitted, nor is the use of
spacer plates or brake dust shields. This inva-
lidates the General Operating Permit for the
vehicle. Notes on selecting, fitting and replacing
tyres R
Only fit tyres and wheels of the same type
and make.
R Only fit tyres of the correct size onto the
wheels.
R After fitting new tyres, run them in at mod-
erate speeds for the first 100 km as they
only reach their full performance after this
distance.
R Fit new tyres on the front wheels first if
tyres of the same size are required on the
fron tand rea rwheels.
R Replace the tyres after six years at the lat-
est, regardless of wear. This also applies to
the collapsible emergency spare wheel* 17
.
R Do not drive with tyres which have too little
tread depth, as this significantly reduces
the traction on wet roads (aquaplaning).
! Store tyres that are not being used in a
cool, dry and preferably dark place. Protect
the tyres against oil, grease, petrol and die-
sel.
Notes on regularly inspecting wheels
and tyres R
Regularly check the wheels and tyres of
your vehicle for damage (e.g. cuts, punctu-
res, tears, bulges on tyres and deformation,
cracks or severe corrosion on wheels), at
least every 14 days, as well as after driving
off-road or on rough roads. Damaged
wheels can cause a loss of tyre pressure.
R Regularly check the tyre tread depth and
the condition of the tread across the whole
width of the tyre (Y page 272). If neces-
sary, turn the front wheels to full lock in
order to inspect the inner side of the tyre
surface.
R All wheels must have a valve cap to protect
the valve against dirt and moisture. Do not
fit anything onto the valve (such as tyre
pressure monitoring systems) other than
17 Only for certain countries. Tyres and wheels

obtained at a qualified specialist workshop,
e.g. from a Mercedes-Benz Service Centre.
Under these circumstances, you should also
restrict the maximum speed of the vehicle
using permanent SPEED-
TRONIC 19
(Y page 245) so that it does not
exceed the maximum permissible speed for
the winter tyres.
Once you have fitted the winter tyres:
X Check the tyre pressures (Y page 272).
X Restart the tyre pressure monitor
(Y page 273).
i Speeds of up to 240 km/h with winter
tyre variant 1: despite what is stated on the
tyre pressure information label (fuel filler
flap), for speeds up to 240 km/ha nd winter
tyre variant 1 (Y page 354), the tyre pres-
sures can be reduced:
R front −40 kPa (−0.4 bar)
R rear −60 kPa (−0.6 bar)
This improves the ride comfort of your vehi-
cle; however, the fuel consumption may
increase slightly. G
Ris
kofa ccident
If you fit the spare wheel* when driving with
winter tyres, bear in mind that driving stability
will be impaired owing to unstable cornering
characteristics caused by the differen ttyres.
You should therefore adapt your driving style
and drive carefully.
Have the spare wheel* replaced at the near-
est qualified specialist workshop which has
the necessary specialist knowledge and tools
to carry out the wor krequired. Mercedes-
Benz recommends that you use a Mercedes-
Benz Service Centre for this purpose. In par-
ticular, work relevant to safety or on safety-
related systems must be carried out at a quali-
fied specialist workshop. Snow chains
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains which
have been specially approved for your vehicle
by Mercedes-Benz, or are of a corresponding
standard of quality.
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.
R snow chains must not be fitted to emer-
gency spare wheels, e.g. Minispare.
R fit snow chains only in pairs and only to the
rear wheels. Observe the manufacturer's
installation instructions.
Do not exceed the maximum permissible
speed of 50 km/h.
i You may wish to deactivate ESP ®
when
pulling away with snow chains fitted
(Y page 47). This way you can allow the
wheels to spin in a controlled manner, ach-
ieving an increased driving force (cutting
action). Winter driving
G
Risk of accident
Do not shift down for additional engine brak-
ing on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Engage neutral.
X Try to bring the vehicle under control using
corrective steering.

Please bear the following in mind
G
Risk of accident
Due to the special tyre tread in combination
with the optimised rubber compound, there is
an increased risk of aquaplaning and skidding
on a damp or wet road surface. Make sure that
ESP ®
is activated for the corresponding road
surface conditions.
Tyre grip is noticeably reduced at low outside
temperatures and low tyre operating temper-
atures. This leads to an increased risk of skid-
ding and resulting vehicle instability. Use win-
ter tyres when the outside temperature falls
below 7†.
If others use the vehicle with the high per-
formance tyres fitted, you as the vehicle
owner must point out the safety guidelines
and/or limitations to these persons.
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres and
wheels which have been approved by
Mercedes-Benz specifically for yourv ehi-
cle. These tyres have been specially adap-
