®
system G
WARNING
The PRE-SAFE ®

system reduces the impact of
an accident on vehicle occupants, as long as
their seat belts have been fastened correctly.
Although your vehicle is equipped with a PRE-
SAFE ®
system, the possibility of injury in the
event of an accident cannot be ruled out. You
should therefore always drive carefully and
adapt your driving style to the prevailing road,
weather and traffic conditions. G
WARNING
Make sure that nobody can become trapped
as you adjust the seat.
! Make

sure that there are no objects in the
footwell or behind the seats when resetting
the seats. There is a risk that the seats
and/or the objects could be damaged.
PRE-SAFE ®
takes preemptive measures to
protect occupants in certain hazardous
situations.
PRE-SAFE ®
intervenes:
R if BAS intervenes, e.g. in emergency
braking situations
R if, on vehicles with DISTRONIC PLUS, BAS
PLUS intervenes powerfully
R if, on vehicles with DISTRONIC PLUS, the
radar sensor system detects an imminent
danger of collision in certain situations
R in critical driving situations, e.g. when
physical limits are exceeded and the
vehicle understeers or oversteers severely
PRE-SAFE ®
takes the following measures
depending on the hazardous situation
detected:
R the front seat belts are pre-tensioned.
R the front-passenger seat is adjusted if it is
in an unfavorable position.

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 and weather
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 tires and
the road surface. Please pay special
attention to the notes on tires,
recommended minimum tire tread depths,
etc. (Y page 326).
In wintry driving conditions, always use
winter tires (M+S tires) and if necessary,
snow chains. Only in this way will the
driving safety systems described in this
section work as effectively as possible. ABS (Anti-lock Braking System)
Important safety notes i
Observe the "Important safety notes"
section ( Y page 63).G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking
characteristics may be severely impaired.
Additionally, further driving safety systems
are

deactivated. There is an increased danger
of skidding and accidents.
Drive on carefully. Have ABS checked
immediately at a qualified specialist
workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp ( Y page 258) and
display messages which may be shown in the
instrument cluster (Y page 229).
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.
Braking 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)
i Observe the "Important safety notes"
section ( Y page 63). 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. 64

Safety

BAS PLUS (Brake Assist System Plus)
i Observe the "Important safety notes"
section ( Y page 63).
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.
BAS PLUS can also react to stationary
obstacles, e.g. stopped or parked vehicles, at
speeds of up to approximately 40 mph
(70 km/h).
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
For speeds above 20 mph (30 km/h): if you
apply the brakes forcefully, BAS PLUS
automatically increases the braking force to
a level suitable for the traffic conditions.
For speeds below 20 mph (30 km/h): if you
apply the brakes, BAS PLUS is activated.
Braking is performed as late as possible.
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.
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:
R
switched on (Y page 223)
R operational ( Y page 243)
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 Driving safety systems
65
Safety Z

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.
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 of up to 40 mph (70 km/h), PRE-
SAFE ®
Brake can also detect stationary
obstacles, for example, 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, preventive passenger protection
measures (PRE-SAFE ®
) are activated
(Y page 52). 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 the 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 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. 70
