When ABS is malfunctioning, other systems,
including driving safety systems, will also
become
inoperative.
Observe the information
on the ABS warning lamp ( Y page 257) and
display messages which may be shown in the
instrument cluster (Y page 224).
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the
vehicle when braking.
ABS works from a speed of about 5 mph
(8 km/h) upwards, regardless of road-surface
conditions. ABS works on slippery surfaces,
even if you only brake gently.
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.
Brakes X
If ABS intervenes: continue
to depress the
brake pedal vigorously until the braking
situation 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
indication of hazardous road conditions, and
functions as a reminder to take extra care
while driving. BAS (Brake Assist System)
G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
BAS operates in emergency braking
situations. If you depress the brake pedal quickly, BAS automatically boosts the braking
force,
thus

shortening the stopping distance.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. BAS PLUS (Brake Assist System Plus)
BAS PLUS is only available in vehicles
equipped with DISTRONIC PLUS.
BAS PLUS provides braking assistance in
hazardous situations at speeds greater than
4 mph (7 km/h) and uses radar sensor
technology to assess the traffic situation.
With the

help of the radar sensor system, BAS
PLUS can detect obstacles that are in the
path of your vehicle for an extended period of
time.
At speeds up to 40 mph (70 km/h), BAS PLUS
may also detect stationary obstacles, for
example, stopped or parked vehicles.
To prevent a front-end collision, BAS PLUS
calculates the brake force necessary if:
R you approach an obstacle, and
R BAS PLUS has detected a risk of collision
At a speed greater than 20 mph
(30 km/h) : if you depress the brake sharply,
BAS PLUS automatically raises the brake
pressure to a value adapted to the traffic
situation.
At a speed less than 20 mph (30 km/h) : if
you depress the brake, BAS PLUS is
activated. The increase in brake pressure will
be carried out at the last possible moment.
If BAS PLUS demands particularly high
braking force, preventative passenger
protection measures (PRE-SAFE ®
) are
activated simultaneously.
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.58
Driving safety systems
Safety

BAS PLUS is deactivated and the brakes
function as usual, if:
R
you release the brake pedal.
R there is
no longer any danger of a rear-end
collision.
R no obstacle is detected in front of your
vehicle.
For BAS PLUS to assist you when driving, the
radar sensor system must be switched on and
operational. You will find further information
under the keyword "Radar sensor system”.
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. G
WARNING
BAS PLUS cannot always clearly identify
objects and complex traffic situations. BAS
PLUS cannot intervene in these cases. There
is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake.
In particular, the detection of obstacles can
be impaired if there is:
R dirt on the sensors or anything else
covering the sensors
R snow or heavy rain
R interference by other radar sources
R the possibility of strong radar reflections,
for example in parking garages
R a narrow vehicle traveling in front, e.g. a
motorbike
R a vehicle

traveling in front on a different line
relative to the center of your vehicle 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
accident.
Always pay careful attention to the traffic
situation and be ready to brake.
Following damage to the front end of the
vehicle, have

the configuration and operation
of the radar sensors checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the front of the vehicle.
i This device has been approved by the FCC
as a "Vehicular Radar System". The radar
sensor is intended for use in an automotive
radar system only. Removing, altering or
tampering with the device will void any
warranties, and is not permitted by the
FCC. Do not tamper with, alter, or use the
device in any non-approved way.
Any unauthorized modification to this
device could void the user's authority to
operate the equipment. ESP

(Electronic Stability Program)
Important safety notes !
Switch the ignition off when:
R the electric

parking brake is being tested
using a brake dynamometer.
R the vehicle is being towed with the rear
axle raised.
Application of the brakes by ESP ®
may
otherwise destroy the brake system.
ESP ®
is deactivated if the å warning lamp
in the instrument cluster lights up
continuously when the engine is running.
If the ÷ warning lamp and the å
warning lamp are lit continuously, ESP ®
is not
available due to a malfunction.
Observe the information on warning lamps
(Y page 259) and display messages which
may be shown in the instrument cluster
(Y page 224). Driving safety systems

Safety Z

If ESP
®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize 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 stabilize the vehicle during braking.
If ESP ®
intervenes, the ÷ ESP®
warning
lamp flashes in the instrument cluster.
If ESP ®
intervenes:
X Do not deactivate ESP ®
under any
circumstances.
X only depress the accelerator pedal as far as
necessary when pulling away.
X adapt your driving style to suit the
prevailing road and weather conditions.
i Only use wheels with the recommended
tire sizes. Only then will ESP ®
function
properly.
ETS (Electronic Traction System) Traction control is part of ESP
®
.
Traction control brakes the drive wheels
individually 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 if you
deactivate ESP ®
.
Deactivating/activating ESP ®
(except
AMG vehicles) G
WARNING
If you deactivate ESP ®
, ESP ®
no longer
stabilizes the vehicle. There is an increased
risk of skidding and an accident.
Only deactivate ESP ®
in the situations
described in the following.
! Avoid spinning the driven wheels for an
extended period with ESP ®
deactivated.
You could

otherwise damage the drivetrain. X
To deactivate: press button :.
The å ESP ®
OFF warning lamp in the
instrument cluster lights up.
X To activate: press button :.
The å ESP ®
OFF warning lamp in the
instrument cluster goes out.
ESP ®
is activated automatically when the
engine is started.
The ECO start/stop function switches the
engine off automatically when the vehicle
stops moving. The engine starts
automatically when the driver wants to pull
away again. ESP ®
remains in its previously
selected status. Example: if ESP ®
was
deactivated before the engine was switched
off, ESP ®
remains deactivated when the
engine is switched on again.
If ESP ®


is deactivated and one or more wheels
start to spin, the ÷ ESP®
warning lamp in
the instrument cluster flashes. In such
situations, ESP ®
will not stabilize the vehicle.
It may be best to deactivate ESP ®
in the
following situations:
R when using snow chains
R in deep snow
R on sand or gravel
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R traction control is still activated.60

ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In
addition to the braking function, ADAPTIVE
BRAKE also has the HOLD function
( Y page 176) and hill start assist
(Y page 138). PRE-SAFE
®
Brake
PRE-SAFE ®
Brake

is only available in vehicles
with DISTRONIC PLUS.
PRE-SAFE ®
Brake can help you to minimize
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.
Starting at a speed of around
4 mph (7 km/h), this function warns you if
you very quickly approach a vehicle in front.
An intermittent warning tone will then sound
and the · distance warning lamp will light
up in the instrument cluster.
X Brake immediately in order to increase the
distance from the vehicle in front.
or
X Take evasive action provided it is safe to do
so.
From a speed of approximately
4 mph (

7 km/h), if the driver and passengers
have fastened their seat belts, PRE-SAFE ®
Brake can brake the vehicle automatically at
speeds up to approximately
124 mph (200 km/h).
Due to the nature of the system, particularly
complicated driving conditions may cause
unnecessary warnings or the unnecessary
intervention of PRE-SAFE ®
Brake. You can end PRE-SAFE
®
Brake
intervention in
a non-critical driving situation at any time by:
R depressing the accelerator pedal further
R activating kickdown
R releasing the brake pedal.
The braking action of PRE-SAFE ®
Brake is
ended automatically if:
R you maneuver to avoid the obstacle.
R there is no longer any danger of a rear-end
collision.
R there is no longer an obstacle detected in
front of your vehicle.
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.
At speeds up to approximately
40 mph (70 km/h), PRE-SAFE ®
Brake can
also detect stationary obstacles such as
stopped or parked vehicles.
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, preventative passenger
protection measures (PRE-SAFE ®
) are
activated (Y page 48).
If, at speeds over 20 mph (30 km/h), a risk
of collision remains and you do not brake,
take evasive action or significantly
accelerate, automatic braking may be
performed up to a level of automatic
emergency braking. Automatic emergency
braking is not performed until immediately
prior to an accident that can no longer be
avoided. G
WARNING
PRE-SAFE ®
Brake will initially brake your
vehicle by a partial application of the brakes
if a

danger of collision is detected. There may
be a collision unless you also brake. Driving safety systems

Safety
Z

Automatic emergency braking cannot prevent
a collision. 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
identify objects and complex traffic
conditions.
In these cases, PRE-SAFE ®
Brake may:
R give an unnecessary warning and then
brake the vehicle
R not give a warning or intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and be ready to brake, especially if
PRE-SAFE ®
Brake warns you. Terminate the
intervention in

a non-critical driving situation.
In particular, the detection of obstacles can
be impaired if there is:
R dirt on the sensors or anything else
covering the sensors
R snow or heavy rain
R interference by other radar sources
R the possibility of strong radar reflections,
for example in parking garages
R a narrow vehicle traveling in front, e.g. a
motorbike
R a vehicle traveling in front on a different line
relative to the center of your vehicle G
WARNING
PRE-SAFE ®
Brake does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As a result, PRE-SAFE ®
Brake may neither
give warnings nor intervene in all critical
situations. There is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake. In
order to maintain the appropriate distance
to the vehicle in front and thus prevent a
collision, you

must apply the brakes yourself.
X To activate/deactivate: activate or
deactivate PRE-SAFE ®
Brake in the on-
board computer ( Y page 214).
When PRE-SAFE ®
Brake is activated, the
Ä symbol appears in multifunction
display, as long as the HOLD function is
deactivated (Y page

176). On vehicles with
Active Parking Assist, the Ä symbol is
displayed when P is engaged or you are
driving faster than 22 mph (35 km/h).
For PRE-SAFE ®
Brake to assist you when
driving, the radar sensor system must be
switched on (Y page 218) and be
operational.
Following damage to the front end of the
vehicle, have

the configuration and operation
of the radar sensors checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the front of the vehicle.
