Important safety notes
If you fail to adapt your driving style or if you
are inattentive, the driving safety systems can
neither reduce the risk of an accident nor
override the laws of physics. Driving safety
systems are merely aids designed to assist
driving. You are responsible for the distance
to the vehicle in front, for vehicle speed and
for braking in good time. Always adapt your
driving style to suit the prevailing road,
weather and traffic conditions and maintain a
safe distance from the vehicle in front. Drive
carefully.
i The driving safety systems described only
work as effectively as possible when there
is adequate contact between the tyres and the road surface. Please pay special atten-
tion to the notes on tyres, recommended
minimum tyre tread depths etc.
(Y page 364).
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. ABS (Anti-lock Braking System)
General notes 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.
The yellow !ABS warning lamp in the
instrument cluster lights up when the ignition
is switched on. It goes out when the engine is running.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 70). G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid- ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
If ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information on the ABS warning lamp (Y page 289) and
display messages which may be shown in the
instrument cluster (Y page 262).
ABS works from a speed of about
8 km/hupwards, regardless of road-surface
conditions. ABS works on slippery surfaces,
even when you only brake gently.
Brakes 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.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions; this serves as a reminder to take extra care while driving. BAS (Brake Assist)
General notes 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. 70
Driving safety systemsSafety
Important safety notes
i
Observe the "Important safety notes" sec-
tion (Y page 70). G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Braking X
Keep the brake pedal depressed firmly 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. BAS PLUS (Brake Assist System Plus)
General notes i
Observe the "Important safety notes" sec-
tion (Y page 70).
BAS PLUS is only available on vehicles with
DISTRONIC PLUS.
For BAS PLUS to assist you, the radar sensor system must be:
R activated (Y page 255)
R operational
With the aid of the radar sensor system, BAS
PLUS can detect obstacles that are in the
path of your vehicle for an extended period of
time.
If the radar sensor system is malfunctioning,
BAS PLUS will not be available. The brake
system is still available with complete brake
boosting effect and BAS. Important safety notes G
WARNING
BAS PLUS cannot always clearly identify
objects and complex traffic situations.
In such cases, BAS PLUS may:
R intervene unnecessarily
R not intervene
There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. Terminate the
intervention in a non-critical driving situation. G
WARNING
BAS PLUS does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As a result, BAS PLUS may not intervene in all
critical situations. There is a risk of an acci-
dent.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
In the event of snowfall or heavy rain, detec-
tion can be impaired.
Detection by the radar sensor system is also
impaired in the event of:
R dirt on the sensors or obscured sensors
R interference by other radar sources
R strong radar reflections, for example, in
multi-storey car parks
R a narrow vehicle travelling in front, e.g. a
motorcycle
R a vehicle travelling in front on a different
line
Following damage to the front end of the vehi-
cle, have the radar sensor settings and oper- ation checked at a qualified specialist work-
shop. This also applies to collisions at slow
speeds where there is no visible damage to
the front of the vehicle. Driving safety systems
71Safety Z
Function
To avoid a collision, BAS PLUS calculates the
brake force necessary if:
R you approach an obstacle and
R BAS PLUS has detected a risk of collision
When driving at a speed under 30 km/h : if
you depress the brake pedal, BAS PLUS is
activated. Braking assistance from BAS PLUS is carried out at the last possible moment.
When driving at a speed above 30 km/h : if
you depress the brake pedal sharply, BAS
PLUS automatically increases the brake pres- sure to a degree suited to the traffic situation.
BAS PLUS provides braking assistance in haz- ardous situations at speeds above 7 km/h.
At speeds of up to approximately 70 km/h,
BAS PLUS can also detect stationary objects.
Examples of stationary objects are stopped or parked vehicles.
i If BAS PLUS demands particularly high
braking force, preventative passenger pro-
tection measures (PRE-SAFE ®
) are activa-
ted simultaneously.
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
BAS PLUS is deactivated and the brakes func-
tion as usual, if:
R you release the brake pedal
R there is no longer a risk of collision
R no obstacle is detected in front of your
vehicle Adaptive brake lamps
i Observe the "Important safety notes" sec-
tion (Y page 70).
The adaptive brake lights warn following traf- fic in an emergency braking situation:
R by flashing brake lamps
R the hazard warning lamps are activated If you brake sharply from a speed of more
than 50 km/h or if braking is assisted by BAS
or BAS PLUS, the brake lamps flash rapidly. In
this 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. If the
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 button (Y page 126). ESP
®
(Electronic Stability Program)
General notes i
Observe the "Important safety notes" sec-
tion (Y page 70).
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. 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 slippery roads. ESP ®
can also stabilise the vehicle during braking.
ETS/4ETS (Electronic Traction System) ETS/4ETS 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 trans-
ferred to the wheel or wheels with traction.
Traction control remains active if you deacti-
vate ESP ®

Driving safety systemsSafety
ESP
®
trailer stabilisation does not work if
ESP ®
is deactivated or disabled because of a
malfunction. EBD (electronic brake force distribu-
tion)
General notes EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking.
Important safety notes i
Observe the "Important safety notes" sec-
tion for driving safety systems (Y page 70).G
WARNING
If EBD has malfunctioned, the rear wheels can still lock, e.g. under full braking. This increa-
ses the risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have the brake system checked at a qualified spe-
cialist workshop.
Observe information regarding indicator and
warning lamps (Y page 289) as well as dis-
play messages (Y page 264).ADAPTIVE BRAKE
i Observe the "Important safety notes" sec-
tion (Y page 70).
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In addi-
tion to the braking function, ADAPTIVE BRAKE also has the HOLD function (Y page 200)and
hill start assist (Y page 162). PRE-SAFE
®
Brake
General notes i
Observe the "Important safety notes" sec-
tion (Y page 70).
PRE-SAFE ®
Brake is only available on vehicles
with DISTRONIC PLUS.
For PRE-SAFE ®
Brake to assist you when driv-
ing, the radar sensor system must be:
R activated (Y page 255)
R operational
With the help of the radar sensor system,
PRE-SAFE ®
Brake can detect obstacles that
are in front of your vehicle for an extended
period of time.
PRE-SAFE ®
Brake can help you to minimise
the risk of a collision with a vehicle ahead or
reduce the effects of such a collision. If PRE-
SAFE ®
Brake has detected a risk of collision,
you will be warned visually and acoustically as
well as by automatic braking. PRE-SAFE ®
Brake cannot prevent a collision without your intervention.
Important safety notes G
WARNING
PRE-SAFE ®
Brake will initially brake your vehi-
cle by a partial application of the brakes if a
danger of collision is detected. There may be
a collision unless you also brake. Automatic
emergency braking cannot prevent a colli-
sion. There is a risk of an accident.
Always apply the brakes yourself and try to
take evasive action. G
WARNING
PRE-SAFE ®
Brake cannot always clearly iden-
tify objects and complex traffic conditions.
In these cases, PRE-SAFE ®
Brake may:
R give an unnecessary warning and then
brake the vehicle
R neither give a warning nor intervene
There is a risk of an accident. 76
Driving safety systemsSafety
The braking action of PRE-SAFE
®
Brake is
ended automatically if:
R you manoeuvre to avoid the obstacle
R there is no longer any danger of a collision
R there is no longer an obstacle detected in
front of your vehicle
If you approach an obstacle and PRE-SAFE ®
Brake detects a risk of a collision, the system
will alert you both visually and acoustically. If you do not brake or take evasive action, the
system will warn you by automatically braking
the vehicle gently. If there is an increased risk
of collision, preventive passenger protection
measures (PRE-SAFE ®
) are activated
(Y page 54). If a risk of collision remains at
speeds over 30 km/h and you do not brake,
take evasive action or significantly acceler-
ate, automatic braking may be performed up
to a level of automatic emergency braking.
Automatic emergency braking is not per-
formed until immediately prior to an accident
that can no longer be avoided. Anti-theft systems
