In this section, you will find information about
the following driving safety systems:
R ABS ( Anti-lock BrakingSystem)
R BAS ( Brake Assist System)
R BAS PLUS ( BrakeAssist System Plus*)
R Adaptive brake lamps
R ESP ®
(Electronic StabilityProgram)
R EBD ( Electronic Brake-force Distribution)

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 adapty our driving
style to the prevailing road and weather con-
ditions. Maintain sufficient distance from
other road users and objects on the road.
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. 56
Driving safety systemsSafety

If ESP
®
intervenes, the ÷warning lamp
flashes in the instrument cluster. G
Risk of accident
If the ÷ 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 yourd riving style to suitt he prevail-
ing road and weather conditions.
Otherwise, the vehicle could go into a skid.
ESP ®
cannot reduce the risk of an accident if
you drive too fast. ESP ®
cannot override the
laws of physics.
! Switch the ignition off when:
R the parking brake is being tested using a
dynamometer
R the vehicle is being towed with the front/
rear axle raised
Application of the brakes by ESP ®
may oth-
erwise destroy the brake system.
! Do not tow vehicles with 4MATIC with the
front or rear axle raised.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
ETS/4ETS (Electronic Traction System) 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. On vehicles with 4MATIC, more drive
torque is also transferred to the wheel or
wheels with traction.
Traction control remains active if you deacti-
vate ESP ®
. G
Risk of accident
Traction control cannot reduce the risk of an
accident if you drive too fast. Traction control
cannot override the laws of physics.
Deactivating/activating ESP ®
(except
AMG vehicles) ESP
®
is activated automatically when the
engine is started.
It may be best to deactivate ESP ®
in the fol-
lowing situations:
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.E SP®
will
otherwise not be able to stabilise the vehicle
if the vehicle starts to skid or a wheel starts
to spin.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R the engine's torque is no longer limited and
the drive wheels can spin. The spinning of
the wheels results in a cutting action, which
provides bette rgrip.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
If ESP ®
is deactivated and one or more wheels
start to spin, the ÷ESP®
warning lamp in
the instrument cluster flashes. In such situa-
tions, ESP ®
will not stabilise the vehicle.

mode
ESP
®
is activated automatically when the
engine is started.
It may be best to activate SPORT handling
mode in the following situations:
R when using snow chains
R in deep snow
R on sand or gravel
Otherwise, you should only use SPORT han-
dling mode on designated race circuits. G
Risk of accident
Deactivate SPORT handling mode and acti-
vate ESP ®
as soon as the situations described
above no longer apply. Otherwise, SPORT
handling mode will only be able to stabilise
the vehicle to a limited degree if the vehicle
starts to skid or a wheel starts to spin.
When SPORT handling mode is activated:
R ESP ®
only improves driving stability to a
limited degree.
R the engine's torque is restricted to a limited
degree and the drive wheels can spin. The
spinning of the wheels results in a cutting
action, which provides better grip. R
traction control is still activated.
R ESP ®
still provides support when you brake
firmly.
If SPORT handling mode is activated and one
or more wheels start to spin, the ÷ESP®
warning lamp in the instrument cluster
flashes. ESP ®

cause the drive wheels to los
etheir 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 Shift the transmission to position N.
X Try to bring the vehicle under control by
using corrective steering.
i For more information on driving with
snow chains, see (Y page 304).Driving systems
Cruise control
Important safety notes Cruise control maintains a constant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden, you must select shift range
1, 2or 3in good time. By doing so, you will
make use of the braking effect of the engine,
which relieves the load on the brake system
and prevents the brakes from overheating
and wearing too quickly. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 30 km/h. G
Risk of accident
Cruise control cannot take account of road
and traffic conditions.
Always pay attention to traffic conditions
even when cruise control is activated. Cruise control is only an aid designed to assist
driving. You are responsible for the vehicle's
speed and for braking in good time.
G
Risk of accident
Do not use cruise control:
R in road and traffic conditions which do not
allow you to maintain a constant speed (e.g.
heavy traffic or winding roads). You could
otherwise cause an accident.
R on slippery roads. Braking or accelerating
could cause the drive wheels to lose trac-
tion and the vehicle could then skid.
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
Cruise control lever You can operate cruise control and variable
SPEEDTRONIC with the cruise control lever.

Driving systemsDriving and parking

Make sure when parking that you position
your vehicle so that it does not make con-
tact with the kerb as the vehicle is lowered.
Your vehicle could otherwise be damaged.
Setting the vehicle level
Select the "Normal" setting for normal road
surfaces and "Raised" for driving with snow
chains or on particularly poor road surfaces.
Your selection remains stored even if you
remove the key from the ignition lock. G
Risk of injury
Make sure that nobody is in the vicinity of the
wheel housing or under the vehicle while low-
ering the vehicle when it is stationary. Other-
wise, limbs could become trapped. Setting raised level

Suspension tuning General notes
The electronically controlled damping system
works continuously.T
his improves driving
safety and ride comfort.
The damping is tuned individually to each
wheel and depends on:
R your driving style, e.g. sporty
R the road surface condition,e .g. bumps
R your individual selection, i.e .sports or com-
fort
Your selection remains stored even if you
remove the key from the ignition lock. Sports tuning
The firmer suspension tunin

Driving systemsDriving and parking

procedure is calculated, e. g. overhanging
loads, tail sections or loading ramps of goods
vehicles. In some circumstances, Active Park-
ing Assist may therefore guide you into the
parking space too early. This may lead to a
collision. For this reason, you should avoid
using Active Parking Assist in such situations.
G
Risk of accident
The front of the vehicle will veer out in the
direction of the oncoming traffic during the
parking operation .Insome cases the vehicle
will also take you onto sections of the oncom-
ing lane during the parking procedure.
You are responsible for safety at all times and
must pay attention to any road users
approaching or passing. Stop the vehicle if
necessary or cancel the Active Parking Assist
parking procedure. G
Risk of injury
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
Use Active Parking Assist for parking spaces:
R that are parallel to the direction of travel
R that are on straight roads, not bends
R that are on the same level as the road, e.g.
not on the pavement
Parking tips:
R on narrow roads, drive as closely as possi-
ble past the parking space.
R parking spaces that are littered, overgrown
or partially occupied by trailer drawbars
might be identified incorrectly or not at all.
R snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R pay attention to the PARKTRONIC
(Y page 171) warning messages during the
parking procedure.
R you can intervene in the steering procedure
to correct it at any time. Active Parking
Assist will then be cancelled. R
when transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
R never use Active Parking Assist when snow
chains or an emergency spare wheel are
fitted.
R make sure that the tyre pressures are
always correct. This has adirec tinfluence
on the parking characteristics of the vehi-
cle.
R the way your vehicle is positioned in the
parking space after parking is dependent
on various factors .These include the posi-
tion and shape of the vehicles parked in
front and behind it and the conditions of the
location. In some cases, Active Parking
Assist may guide you too far into a parking
space, or not far enough into it. In some
cases, it may also lead you across or onto
the kerb. If necessary, you should abort the
parking procedure with Active Parking
Assist.
R you can also engage forward gear prema-
turely. The vehicle redirects and does not
drive as far into the parking space. Should
a gear be changed too early to achieve a
sensible parking position, the parking pro-
cedure will be aborted.
! If unavoidable, you should drive over
obstacles such as kerbs slowly and not at
a sharp angle. Otherwise, you may damage
the wheels or tyres.
Detecting parking spaces Active Parking Assist is switched on automat-
ically when driving forwards. The system is
operational at speeds of up to approximately
35 km/h. While in operation, the system inde-
pendently locates and measures parking
spaces on both sides of the vehicle. When
driving at speeds below 35 km/h, you will see
the parking symbol as a status indicator in the
instrumentc luster.Active Parking Assist only
displays parking spaces on the front-
passenger side as standard .Parking spaces
on the driver's side are displayed as soon as 174
Driving systemsDriving and parking

Only winter tyres bearing the
isnowflake
symbol in addition to the M+S marking pro-
vide the best possible grip in wintry road con-
ditions. Only these tyres will allow driving
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
Risk of accident
M+S tyres with a tread 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 a lower 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 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 SPEEDTRONIC so that it
does not exceed the maximum permissible
speed for the M+S tyres(Y page 164).
When you have fitted the M+S tyres:
X Check the tyre pressures (Y page 305).
X Restart the tyre pressure monitor
(Y page 308). G
Risk of accident
If you fit the spare wheel when driving with M
+S tyres, bear in mind that driving stability will
be impaired due to unstable cornering char-
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 Centre for this purpose. In particular,
work relevant to safety or on safety-related
systems must be carried out at a qualified
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, or that are of a corre-
sponding standard of quality.
If you intend to fit snow chains, please bear
the following points in mind:
R you may not attach snow chains to all
wheel-tyre combinations; see the informa-
tion under "Wheels and tyres" in the "Tech-
nical data" section.
R snow chains must not be fitted to emer-
gency spare wheels, e.g. a "Minispare" or
collapsible emergency spare wheel.
R only fit snow chains in pairs and to the rear
wheels, even on vehicles with 4MATIC.
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 hub-
caps may otherwise be damaged.
On vehicles with AIRMATIC, you must drive at
raised vehicle level if snow chains have been
fitted (Y page 167).
Do not exceed the maximum permissible
speed of 50 km/h.
i You may wish to deactivate
ESP ®
(Y page 58) when pulling away with
snow chains fitted. This way you can allow
the wheels to spin in a controlled manner, 304
Winter operationWheels and tyres

rofitted tyre pressure monitors which are
screwed on to the valve may overload it and
cause it to fail .Due to their design, the valve
is kept open continuously, which may lead to
air loss. G
Ris
kofa ccident
Should the tyre pressure drop repeatedly:
R check the tyre for foreign bodies.
R check whether the wheel is losing air or the
valve is leaking.
R make sure that only a valve cap approved
by Mercedes-Benz is fitted on the tyre
valve.
Tyre pressures that are to olow have a nega-
tive effect on vehicle safety, which could lead
you to cause an accident.
If possible, only correc ttyre pressures when
the tyres are cold. The tyres are cold when
the vehicle has been parked fo ratleast three
hours or has been driven less than 1.5 km.
Depending on the ambient temperature, the
speed you are driving at and the load on the
tyres, the tyre temperature and thus the tyre
pressure may change by approximately
10 kPa (0.1 bar, 1.5 psi) per 10 †. Take this
into accoun twhen checking the pressure of
warm tyres and only correct it if it is too low
for the current operating conditions.
Driving with tyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R cause increased tyre damage
R have a negative effect on handling charac-
teristics and thus the driving safety (e.g. by
causing aquaplaning)
i The tyre pressure values given for low
loads are minimum values which offer you
good ride comfort characteristics.
However, you can also use the values given
for higher loads. These are permissible and
will not adversely affect the running of the
vehicle. H
Environmental note
Check the tyre pressure regularly, at least
every 14 days. Tyre pressure loss warning system
Important safety notes While the vehicle is in motion, the tyre pres-
sure loss warning system monitors the set
tyre pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in a tyre. If the speed
of rotation of a wheel changes as a result of
a loss of pressure, a corresponding warning
message will appearint
he multifunction dis-
play. G
Risk of accident
The tyre pressure loss warning system does
not warn you of an incorrectly set tyre pres-
sure. The table on the inside of the fuel filler
flap will help you decide whether the tyre
pressures should be corrected.
The tyre pressure loss warning system does
not replace the need to regularly check your
vehicle's tyre pressures, since an even loss of
pressure on several tyres at the same time
cannot be detected by the tyre pressure loss
warning system.
The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tyre is penetrated by a foreign object.
In the event of a sudden loss of pressure, bring
the vehicle to a halt by braking carefully. Do
not make any sudden steering movements
when doing so.
The function of the tyre pressure loss warning
system is limited or delayed if:
R snow chains are fitted to your vehicle's
tyres.
R road conditions are wintry.
R you are driving on sand or gravel. 306
