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 BAS PLUS* ( Brake Assist System Plus*)
R Adaptive brake lamps
R ESP ®
( Electronic Stability Program)
R EBV (electronic brake-power distribution)
R ADAPTIVE BRAKE
R Distance warning function* (vehicles with
Distronic*)
R PRE-SAFE ®
Brake* (vehicles with Distronic
Plus*)
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 your driving
style to suit prevailing road and weather con-
ditions. Maintain sufficient distance from
other road users and objects on the road. 48

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, BAS PLUS* 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. 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. BAS PLUS* (Brake Assist Plus)
BAS PLUS provides braking assistance in haz-
ardous situations and uses radar sensor tech-
nology to assess the traffic situation. G
Risk of accident
BAS PLUS is only an aid to assist you when
driving. You are responsible for maintaining a
safe distance from other vehicles, for the vehi-
cle's speed and for braking in good time.
Always pay attention to the traffic conditions.
You may otherwise recognise dangers too
late, cause an accident and injure yourself
and others.
BAS PLUS can detect obstacles that are in the
path of your vehicle for an extended period of
time. Should you approach a detected obsta-
cle quickly, BAS PLUS calculates the braking
force necessary to avoid a rear-end collision.
Should you additionally apply the brakes, BAS
PLUS will automatically increase the braking
force to a level suitable for the traffic condi-
tions.
If BAS PLUS demands particularly high brak-
ing force, PRE-SAFE ®
is activated simultane-
ously.
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking. Driving safety systems

Overview of driving systems
The vehicle's driving systems are described
on the following pages:
R cruise control, Distronic*, Distronic Plus*
and Speedtronic, which are used to control
the speed of the vehicle
R HOLD, which makes pulling away easier,
particularly on steep uphill gradients
R AIRMATIC* and Active Body Control (ABC),
which is used to adjust the vehicle’s sus-
pension system
R 4MATIC* (permanent four-wheel drive), for
optimum traction
R PARKTRONIC and Park Assist*, which
assist you when parking
R reversing camera*, which assists you when
parking
R Night View Assist*, which assists you when
driving in the dark
R Parking Guidance*, which assists you when
looking for a parking space and assists you
when parking
R Blind Spot Assist*, which assists you when
changing lanes
The ABS, BAS, BAS PLUS*, adaptive brake
lights, ESP ®
, EBV, ADAPTIVE BRAKE, distance
warning function* and PRE-SAFE ®
Brake*
driving systems are described in the "Driving
safety systems" section (Y page 48).Cruise control
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 systems

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
R MOE = Mercedes-Benz Original Exten-
ded* (with run-flat characteristics)
Mercedes-Benz Original Extended tyres*
should only be used on wheels that have
been specifically approved by Mercedes-
Benz.
If you use other tyres, wheels or accesso-
ries Mercedes-Benz cannot accept any
responsibility for damage that may result.
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 replac-
ing 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
front and rear wheels.
R Replace the tyres after six years at the lat-
est, regardless of wear. This also applies to
the spare wheel*.
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- 296

short time. This is rectified after a few
minutes of driving, and the tyre pressures
are displayed for the correct positions.
Interchanging the wheels
G
Risk of accident
Interchange the front and rear wheels only if
they have the same dimensions: for example
size, offset, etc.
After every wheel interchange/change, have
the tightening torque checked at a qualified
specialist workshop that has the necessary
specialist knowledge and tools to carry out
the work required. Mercedes-Benz recom-
mends that you use a Mercedes-Benz Service
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified spe-
cialist workshop.
The wheels could work loose if they are not
tightened to a torque of 150 Nm.
For safety reasons, Mercedes-Benz recom-
mends that you only use wheel bolts of the
correct size which have been approved for
Mercedes-Benz vehicles.
The wear patterns on the front and rear tyres
differ, depending on the operating conditions.
Interchange the wheels before a clear wear
pattern has formed on the tyres. Front tyres
typically wear more on the shoulders and the
rear tyres in the centre.
Interchange the wheels every 5,000 km to
10,000 km depending on the degree of tyre
wear, provided that the vehicle has the same
size front and rear tyres. Do not reverse the
direction of tyre rotation.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is interchanged. Check the tyre pressure and,
if necessary, restart the tyre pressure loss
warning system or the tyre pressure moni-
tor*. !
On vehicles fitted with a tyre pressure
monitor*, electronic components are loca-
ted in the wheel.
Tyre-fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Always have the wheels interchanged/
changed at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre. 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.
Observe the notes in the "Changing a wheel"
section (Y page 302). Winter tyres
Use winter tyres at temperatures below
+7 ˚C and in wintry road conditions. Only
winter tyres displaying the isnowflake
symbol in addition to the M+S marking pro-
vide optimum grip in wintry road conditions.
Only these tyres will allow the ABS, ESP ®
and
4MATIC* driving systems to function opti-
mally in winter, as these tyres have been
designed specifically for driving in 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 302
