Important safety notes
!
Make sure that there are no objects in the
footwell or behind the seats. There is a risk
that the seats and/or the objects could be
damaged when PRE-SAFE ®
is activated.
Although your vehicle is equipped with PRE-
SAFE ®
, the possibility of injury in the event of an
accident cannot be ruled out. 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.
Function PRE-SAFE
®
intervenes:
R in emergency braking situations, e.g. when
BAS is activated
R in critical driving situations, e.g. when physi-
cal limits are exceeded and the vehicle under- steers or oversteers severely
R on vehicles with the Driving Assistance pack-
age: if BAS PLUS intervenes powerfully or the
radar sensor system detects an imminent
danger of collision in certain situations
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detected:
R the front seat belts are pre-tensioned
R if the vehicle skids, the front side windows are
closed
R vehicles with the memory function: the front-
passenger seat is adjusted if it is in an unfav-
ourable position
R vehicles with a multicontour seat: the air pres-
sure in the side bolsters of the backrest is
increased
If the hazardous situation passes without result-
ing in an accident, PRE-SAFE ®
slackens the belt
pre-tensioning. On vehicles with multicontour
seats, the air pressure in the side bolsters is
reduced again. All settings made by PRE-SAFE ®
can then be reversed.
If the seat belt pre-tensioning is not reduced:
X Move the seat backrest or seat back slightly
when the vehicle is stationary.
Seat belt pre-tensioning is reduced and the
locking mechanism is released.
The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. Informa-
tion about the convenience function can be
found under "Belt adjustment" (Y page 41). PRE-SAFE
®
PLUS (anticipatory occu-
pant protection PLUS)
Introduction PRE-SAFE
®
PLUS is only available in vehicles
with the Driving Assistance package.
Using the radar sensor system, PRE-SAFE ®
PLUS is able to detect that a head-on or rear-end collision is imminent. In certain hazardous sit-
uations, PRE-SAFE ®
PLUS takes pre-emptive
measures to protect the vehicle occupants.
Important safety notes The intervention of PRE-SAFE
®
PLUS cannot
prevent an imminent collision.
The driver is not warned before the intervention
of PRE-SAFE ®
PLUS.
PRE-SAFE ®
PLUS does not intervene:
R if the vehicle is reversing
R when the vehicle is towing a trailer and there
is a risk of a rear-end collision
When driving, or when parking or exiting a park- ing space with assistance from Active Parking
Assist, PRE-SAFE ®
PLUS will not apply the
brakes.
Function PRE-SAFE
®
PLUS intervenes in certain situa-
tions if the radar sensor system detects an
imminent head-on or rear-end collision.
PRE-SAFE ®
PLUS takes the following measures
depending on the hazardous situation detected:
R if the radar sensor system detects that a
head-on collision is imminent, the seat belts
are pre-tensioned
R if the radar sensor system detects that a rear-
end collision is imminent:
- the rear hazard warning lamps are activa-
ted and flash at a higher frequency
- the brake pressure is increased if the driver
applies the brakes when the vehicle is sta-
tionary
- the seat belts are pre-tensioned 48
Occupant safetySafety

ABS (Anti-lock Braking System)
General notes 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.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from a speed of about 8 km/h,
regardless of road-surface conditions. ABS
works on slippery surfaces, even when you only
brake gently.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 61). 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.
If ABS is malfunctioning, other systems, includ-
ing driving safety systems, will also become
inoperative. Observe the information on the ABS warning lamp (Y page 256) and display mes-
sages which may be shown in the instrument
cluster (Y page 230).
Brakes X
If ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation 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; this serves as a
reminder to take extra care while driving. BAS (Brake Assist)
General notes 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" sec-
tion (Y page 61). G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Brakes 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 PLUS) with
Cross-Traffic Assist
General notes BAS PLUS can help you to minimise the risk of a
collision with a vehicle or a pedestrian and
reduce the effects of such a collision. If BAS
PLUS detects a danger of collision, you are
assisted when braking.
i Pay attention to the important safety notes
in the "Driving safety systems" section
(Y page 61).
BAS PLUS is only available on vehicles with the
Driving Assistance package.
For BAS PLUS to assist you when driving, the
radar sensor system and the camera system
must be operational. 62
Driving safety systemsSafety

Function
To avoid a collision, BAS PLUS calculates the
brake force necessary if:
R you approach an obstacle and
R BAS PLUS has detected a risk of a collision
When driving at a speed under 30 km/h: if
you depress the brake pedal, BAS PLUS is acti-
vated. Braking assistance from BAS PLUS is car-
ried out at the last possible moment.
When driving at a speed above 30 km/h: if
you depress the brake pedal sharply, BAS PLUS automatically increases the brake pressure to adegree suited to the traffic situation.
BAS PLUS provides braking assistance in haz-
ardous situations with vehicles in front within a
speed range between 7 km/h and 250 km/h.
Up to a speed of approximately 70 km/h, BAS
PLUS may react 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 obstacles crossing your path, which move in
the detection range of the sensors and are
detected
i If BAS PLUS demands particularly high brak-
ing force, preventative passenger protection
measures (PRE-SAFE ®
) are activated simulta-
neously.
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 func-
tion 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 COLLISION PREVENTION ASSIST
PLUS
General notes i
Observe the "Important safety notes" sec-
tion (Y page 61).
COLLISION PREVENTION ASSIST PLUS consists of a distance warning function with an autono- mous braking function and Adaptive Brake
Assist.
COLLISION PREVENTION ASSIST PLUS can help
you to minimise the risk of a collision with the
vehicle in front or reduce the effects of such a
collision.
If COLLISION PREVENTION ASSIST PLUS
detects that there is a risk of a collision, you will
be warned visually and acoustically. If you do not react to the visual and audible collision warning,
autonomous braking can be initiated in critical
situations. If you apply the brake yourself in a
critical situation, the COLLISION PREVENTION
ASSIST PLUS Adaptive Brake Assist assists you.
Important safety notes In particular, the detection of obstacles can be
impaired in the case of:
R dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other radar sources
R strong radar reflections, for example, in multi-
storey car parks
R a narrow vehicle travelling in front, e.g. a
motorcycle
R a vehicle travelling in front on a different line
R new vehicles or after a service on the COLLI-
SION PREVENTION ASSIST PLUS system
Please observe the information in the section on running-in the vehicle (Y page 138).
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 slow speeds where there is no visible damage to thefront of the vehicle.
Activating/deactivating The COLLISION PREVENTION ASSIST PLUS is
automatically active after switching on the igni-
tion.
You can activate or deactivate COLLISION PRE-
VENTION ASSIST PLUS in the on-board com-
puter (Y page 221). When deactivated, the dis-
tance warning function and the autonomous
braking function are also deactivated.
If COLLISION PREVENTION ASSIST PLUS is
deactivated, the æsymbol appears in the
assistance graphics display. 64
