Overview of driving safety systems
In this section, you will find information about the following driving safety systems:
R ABS ( Anti-lock BrakingSystem)
(Y page 69)
R BAS ( Brake Assist System) (Y page 70)
R BAS PLUS (B rakeAssist System PLUS) with
Cross-Traffic Assist (Y page 70)
R COLLISION PREVENTION ASSIST PLUS
(distance warning function and adaptive
Brake Assist) (Y page 72)

R EBD ( Electronic Brake force Distribution)
(Y page 78)
R ADAPTIVE BRAKE (Y page 78)
R PRE-SAFE ®
Brake (Y page 78)
R STEER CONTROL (Y page 80) Important safety notes
If you fail to adapt your driving style or
become distracted, the driving safety sys-
tems can neither reduce the risk of accident
nor override the laws of physics. Driving
safety systems are merely aids designed to
assist driving. You are responsible for the dis-
tance 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 In wintry driving conditions, always use
winter tires (M+S tires) 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 information 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 0025ABS 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 69). 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.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information on the ABS warning lamp (Y page 282) and
display messages which may be shown in the
instrument cluster (Y page 252).
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface condi-
tions. ABS works on slippery surfaces, even if
you only brake gently. Driving safety systems

dling mode
If SPORT handling mode is activated and one
or more wheels start to spin, the 00E5ESP®
warning lamp in the instrument cluster
flashes. ESP ®
only stabilizes the vehicle to a
limited degree.
When SPORT handling mode is activated:
R ESP ®
only improves driving stability to a
limited degree.
R traction control is still activated.
R engine torque is only restricted to a limited
degree, and the drive wheels are able to
spin.
The spinning of the wheels results in a cut- ting action for better traction on loose sur-
faces.
R ESP ®
still provides support when you
brake.
Characteristics when ESP ®
is deactivated
If ESP ®
is deactivated and one or more wheels
start to spin, the 00E5ESP®
warning lamp in
the instrument cluster does not flash. In such
situations, ESP ®
will not stabilize the vehicle.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R engine torque is restricted to a limited
degree and the drive wheels are able to
spin.
The spinning of the wheels results in a cut-
ting action for better traction on loose sur-faces.
R traction control is still activated.
R PRE-SAFE ®

X
Brake immediately to defuse the situation.
or X Take evasive action provided it is safe to do
so.
PRE-SAFE ®
Brake can also brake the vehicle
automatically under the following conditions:
R the driver and front-passenger have their
seat belts fastened
and
R the vehicle speed is between approx-
imately 4 mph (7 km/h) and 124 mph
(200 km/h)
At a speed of up to approximately 44 mph
(70 km/h), PRE-SAFE ®
Brake can also detect:
R stationary objects in the path of your vehi-
cle, e.g. stopped or parked vehicles
R pedestrians in the path of your vehicle
i If there is an increased risk of collision,
preventive passenger protection measures
(PRE-SAFE ®
) are activated.
If the risk of collision with the vehicle in front
remains and you do not brake, take evasive
action or accelerate significantly, the vehicle
may perform automatic emergency braking,
up to the point of full brake application. Auto- matic emergency braking is not performed
until immediately prior to an imminent acci-
dent.
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 a risk of collision.
R there is no longer an obstacle detected in
front of your vehicle. STEER CONTROL
General information STEER CONTROL helps you by transmitting a
noticeable steering force to the steering
wheel in the direction required for vehicle
stabilization.
This steering assistance is provided in partic-
ular if:
R both right wheels or both left wheels are on
a slippery road surface when you brake
heavily.
R the vehicle starts to skid.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 69).
No steering support is provided from STEER
CONTROL, if:
R ESP ®
is malfunctioning.
R the lighting is faulty.
