BAS (Brake Assist System)
i Observe the "Important safety notes"
section ( Y page 64). 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.
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)
i Observe the "Important safety notes"
section ( Y page 64).
BAS PLUS is only available in vehicles
equipped with DISTRONIC PLUS.
For BAS PLUS to assist

you when driving, the
radar sensor system must be:
R activated (Y page 229)
R operational
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.
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. BAS PLUS provides braking assistance in
hazardous situations at speeds greater than
4 mph (7 km/h).
At speeds of up to approximately 40 mph
(70 km/h), BAS PLUS can also detect
stationary objects. Examples of stationary
objects are 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

less than 20 mph (30 km/h) : if
you depress the brake pedal, BAS PLUS is
activated. Braking is performed as late as
possible.
At a speed greater than 20 mph
(30 km/h) : if you depress the brake pedal
sharply, BAS PLUS automatically raises the
brake pressure to a value adapted to the
traffic situation.
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
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. 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 Driving safety systems
65
Safety Z

R
there are 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. ESP
®
(Electronic Stability Program)
General notes i
Observe the "Important safety notes"
section ( Y page 64).
ESP ®
monitors driving stability and traction,
i.e. power transmission between the

tires 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 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. ETS/4ETS (Electronic Traction System) i
Observe the "Important safety notes"
section ( Y page 64).
ETS/4ETS 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. In addition, more drive torque is
transferred to the wheel or wheels with
traction.
Traction control remains active, even if you
deactivate ESP ®
.
Important safety notes i
Observe the "Important safety notes"
section ( Y page 64). G
WARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilize the vehicle. Additionally, further
driving safety systems are deactivated. This
increases the risk of skidding

and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop.
! When testing the electric parking brake
on a braking dynamometer, switch off the
ignition. Application of the brakes by
ESP ®
may otherwise destroy the brake
system.
Vehicles without 4MATIC: observe the notes
on ESP ®
(Y page 322) when towing the
vehicle with a raised rear axle.
! Vehicles with 4MATIC: function or
performance tests may only be carried out
on a 2-axle dynamometer. Before you
operate the vehicle on such a
dynamometer, please consult a qualified
workshop. You could otherwise damage
the drive train or the brake system.
ESP ®
is deactivated if the 00BB warning lamp
in the instrument cluster lights up
continuously when the engine is running. 66
Driving safety systems
Safety

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 00BA 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 front
passenger 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 prevent the intervention of the PRE-
SAFE ®
Brake 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.
At speeds of up to approximately 40 mph
(70 km/h), PRE-SAFE ®
Brake can also detect
stationary objects. Examples of stationary
objects are 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 52). If the risk of collision
with the vehicle in front remains and you do
not brake, take evasive action or accelerate
significantly, automatic braking may be
performed up to a level of 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.
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:
R dirt on the sensors or anything else
covering the sensors
R snow or heavy rain70

interference by other radar sources
R there are strong radar reflections, for
example in parking garages
R a narrow vehicle traveling in front, e.g. a

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 an appropriate distance
from 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 225).
When PRE-SAFE ®
Brake is activated, the
00C7 symbol appears in the multifunction
display as long as the HOLD function is
deactivated ( Y page 179).
On vehicles with Parking Guidance, the
00C7 symbol is displayed when position P
is engaged or you are driving faster than
22 mph (35 km/h ).
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. Theft deterrent locking system
Immobilizer
The immobilizer prevents your vehicle from
being started without the correct SmartKey.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. The
engine can be started by anyone with a valid
SmartKey that is left inside the vehicle.
X To activate with the SmartKey: remove
the SmartKey from the ignition lock.
X To activate with KEYLESS-GO: switch the
ignition off and open the driver's door.
X To deactivate: switch on the ignition.
i The immobilizer is always deactivated
when you start the engine.
In the event that the engine cannot be
started when the starter battery is fully
charged, the immobilizer may be faulty.
