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 asafe 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 note son tires,
recommended minimu mtire tread depths,
etc. (Y page 344).
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)
General information AB
Sr egulates 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.
The yellow 0017ABS 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"
section (Y page 68). 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 ABSi s malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Y page 278) and
display messages which may be shown in the
instrument cluster (Y page 249).
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface
conditions. ABS works on slippery surfaces,
even if you only brake gently.
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 AssistS
ystem)
General information BAS operates in emergency braking
situations. If you depress the brake pedal
quickly, BAS automatically boosts the braking
force, thus shortening the stopping distance.
Important safety notes
i
Observe the "Important safety notes"
section (Y page 68). G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident. Driving safety systems

PLUS) with Cross-Traffic Assist
General information i
Observe the "Important safety notes"
section (Y page 68).
BAS PLUS is only available on vehicles with
the Driving Assistance package.
For BAS PLUS to assist you when driving, the
radars ensor system and the camera system
must be operational.
With the help of a sensor system and a
camera system, BAS PLUS can detect
obstacles:
R that are in the path of your vehicle for an
extended period of time
R that cross the path of your vehicle
In addition, pedestrians in the path of your
vehicle can be detected.
BASP LUS detects pedestrians by using
typical characteristics such as the body
contours and posture of aperson standing
upright.
If the radar sensor system or the camera
system is malfunctioning, BAS PLUS
functions are restricted or no longer
available. The brake system is still available
with complete brake boostin geffect and BAS.
i Observe the restrictions described in the
"Important safety notes"
section“ (Y page 70). BAS PLUS can help you to minimize the risk
of a collision with a vehicle or a pedestrian
and reduce the effects of such a collision. If
BAS PLUS detects a dange
rofcollision, you
are assisted when braking.
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
situation and be ready to brake. Terminate the
intervention in a non-critical driving situation. G
WARNING
BAS PLUS does not react:
R to small people, e.g. children
R to animals
R to oncoming vehicles
R when cornering
As aresult, 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.
In the event of snowfall or heavy rain, the
recognition can be impaired.
Recognition by the radar sensor system is
also impaired in the event of:
R dirt on the sensors or anything else
covering the sensors
R 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
motorbike 70
Driving safet
ysystemsSafety

R
a vehicle traveling in fron tonadifferent line
R vehicles quickly moving into the radar
senso rsystem detection range
Recognition by the camera system is also
impaired in the event of:
R dirt on the camera or if the camera is
covered
R there is glare on the camera system, e.g.
from the sun being low in the sky
R darkness
R if:
-pedestrians move quickly, e.g. into the
path of the vehicle
- the camera system no longer recognizes
a pedestrian as a person due to special
clothing or other objects
- a pedestrian is concealed by other
objects
- the typical outline of a person is not
distinguishable from the background
Following damage to the fron tend of the
vehicle, have the configuratio nand operation
of the rada rsensors checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the fron tofthe vehicle.
Following damage to the windshield, have the
configuration and operation of the camera
system checked at a qualified specialist
workshop.
Function To avoid a collision, BAS PLUS calculates the
brake force necessary if:
R you approach an obstacle, and
R BAS PLUS has detected arisk of collision
When driving at a speed under 20 mph
(30 km/h):ify ou depress the brake pedal,
BAS PLUS is activated. The increase in brake
pressure will be carried out at the last
possible moment.
When driving at a speed above 20 mph
(30 km/h) :ifyou depress the brake pedal
sharply, BAS PLUS automatically raises the brake pressure to a value adapted to the
traffic situation.
BAS PLUS provides braking assistance in
hazardous situations with vehicles in front
within a speed range between
4mph
(7 km/h) and 155 mph (250 km/ h).
At speeds of up to approximately 44 mph
(70 km/h), BAS PLUS reacts to:
R stationary objects in the path of your
vehicle, e.g .stopped or parked vehicles
R pedestrians in the path of your vehicle
R objects crossing your path
i 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 situatio nis 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 a risk of collision
R no obstacle is detected in front of your
vehicle
R you depress the accelerator pedal
R you activate kickdown COLLISIONP

Adaptive Brake Assist
i
Observe the "Importan tsafety notes"
sectio n(Ypage 68). G
WARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic
situations.
In such cases, Adaptive Brake Assist may:
R intervene unnecessarily
R not intervene
There is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake. Terminate the
intervention in a non-critical driving situation. G
WARNING
Adaptive Brake Assist does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R to stationary obstacles
R when cornering
As a result, Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake.
Adaptive Brake Assist aids you in braking
during hazardous situations at speeds above
4m ph (7 km/h) and uses the radar sensor
system to evaluate the traffic situation.
With the help of Adaptive Brake Assist, the
distance warning signal can detec tobstacles
that are in the path of your vehicle for an
extended period of time.
Should you approach an obstacle and
Adaptive Brake Assist has detected a risk of
collision, Adaptive Brake Assist calculates the
braking force necessary to avoid a rear-end
collision. Should you apply the brakes
vigorously, Adaptive Brake Assist will automatically increase the braking force to a
level suitable for the traffic conditions.
X
Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally again 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 fron tofyour
vehicle
Adaptive Brake Assist is then deactivated.
Up to vehicle speeds of around 155 mph
(250 km/h), adaptive Brake Assist is capable
of reacting to moving objects that have
already been recognized as such at least once
over the period of observation. Adaptive
Brake Assist does not react to stationary
obstacles.
If Adaptive Brake Assist is not available due
to a malfunction in the radar sensor system,
the brake system remains available with full
brake boosting effect and BAS.
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 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
Following damage to the front end of the
vehicle, have the configuration and operation
of the radar sensor 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. Driving safety systems
