Overview of driving safety systems
In this section, you will find information about
the following driving safety systems:
R ABS ( Anti-lock Braking System)
R BAS ( Brake Assist System)
R Adaptive brake lamps
R ESP ®
( Electronic Stability Program)
R EBV (electronic brake-power distribution)
i In wintry road conditions, always use win-
ter tyres (M+S tyres) and, where 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 your driving
style to suit 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 prevailing road and weather conditions.
Off-road ABS*(Vehicles with Off-road
engineering package*) An ABS system specifically suited to off-road
terrain is activated automatically once the off-
road drive program (Y
page 107) is activated.
At speeds below 30 km/h, the front wheels
lock cyclically during braking. The digging-in Driving safety systems

i
Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
ESP ®
trailer stabilisation If your trailer begins to lurch, you can only
stabilise the vehicle/trailer combination by
depressing the brake firmly.
In this situation, ESP
®
assists you and detects
if the trailer begins to lurch. ESP ®
slows the
vehicle down by braking and limiting the
engine output until the vehicle/trailer com-
bination has stabilised.
Trailer stabilisation is active above speeds of
about 65 km/h. G
Risk of accident
If road and weather conditions are bad, trailer
stabilisation will not be able to prevent the
trailer from swerving and thereby reduce the
risk of accident. Trailers with a high centre of
gravity can tip over before ESP ®
can detect
this.
Trailer stabilisation does not work if ESP ®
is
deactivated or disabled because of a mal-
function.
ETS (Electronic Traction Support) 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.
Traction control remains active when you
deactivate 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.
i If heavy demands are made on the brakes,
traction control switches off automatically
for a brief period so that the brakes do not heat up even further. If traction control
does not intervene for this reason, the
d
warning lamp in the instrument clus-
ter lights up. In addition the multi-function
display shows one of the following mes-
sages: ESP inoperative (vehicles with 4-
button multi-function steering wheel) or
ESP currently unavail. See Owner's
Manual (vehicles with 12-button luxury
multi-function steering wheel)*.
Activating/deactivating ESP ® ESP
®
is activated automatically when the
engine is running.
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. ESP ®
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. 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.
i If ESP ®
is deactivated and one or more
wheels start to spin, the dwarning lamp
in the instrument cluster flashes. In such
situations, ESP ®
will not stabilise the vehi-
cle. Driving safety systems

Overview of off-road driving systems
The systems which are relevant for off-road
driving are explained on the following pages:
R 4MATIC (permanent four-wheel drive), for
optimum traction
R DSR (Downhill Speed Regulation)* (vehi-
cles with Off-Road Pro engineering pack-
age*), which assists you when driving
downhill
R Off-road driving program* (vehicles with
Off-road Pro engineering package*), which
assists you when driving off-road
You will find further information about driving
off-road in the "Operation" section
(Y page 158). 4MATIC* (permanent four-wheel
drive)
4MATIC ensures that all four wheels are per-
manently driven. Together with ESP ®
and
ETS, it improves the traction of your vehicle
whenever a drive wheel spins due to insuffi-
cient grip. G
Risk of accident
4MATIC cannot reduce the risk of an accident
if you drive too fast.
If a drive wheel spins due to insufficient grip:
R only depress the accelerator pedal as far as
necessary when pulling away.
R accelerate less when driving.
R adapt your driving style to suit road and
traffic conditions.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tyres (M+S tyres), with snow
chains if necessary.
! When testing the parking brake, operate
the vehicle only briefly (for a maximum of
ten seconds) on a brake test dynamometer.
When doing this, turn the key to position
0 or 1in the ignition. Failure to do this can
cause damage to the drive train or the
brake system.
! A function or performance test should
only be carried out on a twin-axle dyna-
mometer. If you wish to operate the vehicle
on such a dynamometer, please consult a
Mercedes-Benz Service Centre in advance.
You could otherwise damage the drive train
or the brake system. DSR (Downhill Speed Regulation)*
(vehicles with the off-road engineer-
ing package*)
You will find information about driving off-
road in the "Operation" section
(Y page 158).
DSR is an aid to assist you when driving down-
hill. It keeps the speed of travel at the speed
selected on the on-board computer. The
steeper the downhill gradient, the greater the
DSR braking effect on the vehicle. When driv-
ing on flat stretches of road or on an uphill Off-road driving

with off-road engineering package*)
The off-road drive program assists you in driv-
ing off-road and when fording. The engine’s
performance characteristics and the gear-
shifting characteristics of the automatic
transmission are adapted for this purpose.
ABS, ESP ®
and ETS programs especially
adapted to off-road driving are also activated.

Points to remember
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres and
wheels which have been approved by
Mercedes-Benz specifically for your vehi-
cle. These tyres have been specially adap-
ted for use with the control systems, such
as ABS or ESP ®
, and are marked as follows:
R MO = Mercedes-Benz Original
If you use other tyres and wheels,
Mercedes-Benz cannot accept any respon-
sibility 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, 150 Tyres and wheelsOperation

H
Environmental note
Check the tyre pressure regularly, at least
every 14 days. Tyre pressure loss warning
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 appear in the multi-function 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 R
you adopt a very sporty driving style (cor-
nering at high speeds or driving with high
rates of acceleration)
R you are towing a very heavy or large trailer
R you are driving with a heavy load (in the
vehicle or on the roof)
Restarting the tyre pressure loss warn-
ing system Restart the tyre pressure loss warning system
if you have:
R
changed the tyre pressure
R changed the wheels or tyres
R fitted new wheels or tyres
X Before restarting, consult the table of tyre
pressures on the inside of the fuel filler flap
to ensure that the tyre pressure in all four
tyres is set correctly for the operating con-
ditions concerned.
X Also observe the notes in the section on
tyre pressures ( Ypage 152). G
Risk of accident
The tyre pressure loss warning system can
only give reliable warnings if you have set the
correct tyre pressure.
If an incorrect tyre pressure is set, these
incorrect values will be monitored.
A tyre with insufficient pressure results in
vehicle instability when driving, thus increas-
ing the risk of an accident.

Winter driving
Points to remember
Have your vehicle winterproofed at a qualified
specialist workshop, e.g. at a Mercedes-Benz
Service Centre, at the onset of winter. Winter tyres
In temperatures below +7 °C, always use all-
weather tyres or winter tyres and always use
winter tyres in wintry road conditions.
Only winter tyres displaying the snowflake
symbol in addition to the M+S marking pro-
vide optimum grip in wintry road conditions.
Only these tyres will allow the ABS and ESP
driving systems to function optimally in win-
ter, as these tyres have been designed spe-
cifically for driving on snow.
Use winter tyres of the same make and tread
on all wheels to maintain safe handling char-
acteristics. G
Risk of accident
Winter tyres with a tread depth of less than
4 mm must be replaced immediately. They are
no longer suitable for winter use and can no
longer provide sufficient grip. This could
cause you to lose control of your vehicle and
cause an accident.
Always observe the maximum permissible
speed specified for the winter tyres you have
fitted. If you fit winter tyres which have a
lower maximum permissible speed than that
of the vehicle, 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* 26
to the max-
imum permissible speed for the winter tyres
(Y page 110).
Once you have fitted the winter tyres: X
Check the tyre pressures (Y page 152).
X Restart the tyre pressure loss warning sys-
tem (Y page 153). G
Risk of accident
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 different tyres.
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 work required. 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 wheels, e.g. a collapsible emergency
spare wheel.
R Fit snow chains only in pairs and only to the
rear wheels. Comply with the manufactur-
er'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 52). This way, you can allow the
