AIRBAG OFF indicator lamp must be con-
tinuously lit.
If you secure a forward-facing child
restraint system to the front-passenger
seat, you must move the front-passenger
sea tas far back as possible.
R make sure there are no heavy or sharp-
edged objects in the pockets of clothing.
R do not lean forwards, e.g. over the cover of
the driver's/front-passenger front airbag,
particularly when the vehicle is in motion.
R do not put your feet on the dashboard.
R only hold the steering wheel on the outside.
This allows the airbag to be fully deployed.
You could be injured if the airbag is
deployed and you are holding the inside of
the steering wheel.
R do not lean on the doors from inside the
vehicle.
R make sure that there are no people, ani-
mals or objects between the vehicle occu-
pants and the area where the airbags are
deployed.
R do not place any objects between the seat
backrest and the door.
R do not hang any hard objects, for example,
coat hangers, on the grab handles or coat
hooks.
R do not attach accessories, e.g. cup holders,
to the doors.
It is not possible to rule out a risk of injury
being caused by an airbag, due to the high
speed at which the airbag must be deployed. G
WARNING
Airbag functionality can only be assured if the
following parts are not covered and no badges
or stickers are attached to them:
R padded steering wheel boss
R front-passenger airbag cover
R door trim
R outer side of seat bolsters G
WARNING
When an airbag deploys, a small amount of
powder is released.T he powder may cause
short-term breathing difficulties to persons
suffering from asthma or other pulmonary
conditions.
In order to prevent potential breathing diffi-
culties, you should leave the vehicle as soon
as it is safe to do so. You can also open the
window to allow fresh air to enter the vehicle
interior. The powder does not constitute a
health hazard and does not indicate that there
is a fire in the vehicle. G
WARNING
The airbag parts are hot after the airbag has
been deployed. Do not touch them as you
could burn yourself.
Have the airbags replaced at a qualified spe-
cialist workshop. Otherwise, occupants are
not protected by the airbags in the event of
another accident.
Front airbags The front airbags increase protection for the
driver's and front-passenger's head and
chest.

Observe the "Important safety notes" sec-
tion (Y page 53).
BAS PLUS assists you in braking during haz-
ardous situations at speeds above 30 km/h
and uses the radar sensor system to evaluate
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.
At speeds up to approximately 70 km/h, BAS
PLUS may also detect stationary obstacles,
for example, stopped or parked vehicles.
Should you approach an obstacle and BAS
PLUS has detected a risk of collision, BAS
PLUS calculates the braking force necessary
to avoid a rear-end collision. Should you
depress the brake sharply, BAS PLUS can
automatically increase the braking force to a
level suitable for the traffic conditions.
If BAS PLUS demands particularly high brak-
ing force, preventative passenger protection
measures (PRE-SAFE ®
) are activated simul-
taneously.
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally againi f:
R you release the brake pedal.
R there is no longe rany dange rofarear-end
collision.
R no obstacle is detected in front of your
vehicle.
BAS PLUS is then deactivated.
Vehicles with COMAND and anavigation sys-
tem: the radar sensor system is switched off
automatically in the vicinity of radio telescope
facilities ( Ypage 312).
Vehicles without COMAND and a navigation
system and vehicles for Australia: the radar
sensor system and on-board computer must
be switched off in the vicinity of radio tele-
scope facilities ( Ypage 194). For BA
SPLUS to assist you when driving, the
radars ensor system must be switched on and
operational; see "Rada rsensor system" in the
index. 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 cover-
ing the sensors
R snow or heavy rain
R interference by other radar sources
R the possibility of strong radar reflections,
for example, in multi-storey car parks
R a narrow vehicle travelling in front, e.g. a
motorbike
R a vehicle travelling in front on a different
line 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
critical situations. There is a risk of an acci-
dent .Always pay careful attention to the traf-
fic situation and be ready to brake.
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensors checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at slow speeds where there is no visible
damage to the front of the vehicle.
If BA SPLUS is not available due to a malfunc-
tion in the radars ensor system, the brake Driving safet

several seconds. The
·distance warn-
ing lamp then lights up in the instrument
cluster.
R you are rapidly approaching the vehicle in
front. An intermittent warning tone will
then sound and the ·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.
If the driver and passengers have fastened
their seat belts, PRE-SAFE ®
Brake can also
can also perform the following at speeds of
above approximately 30 km/h:
R brake the vehicle automatically from a
speed of up to approximately 200 km/h
R trigger preventative passenger protection
measures (PRE-SAFE ®
) (Y page 43)
Due to the nature of the system, particularly
complicated driving conditions may cause
unnecessary warnings or the unnecessary
intervention of PRE-SAFE ®
Brake. To end this,
you can either depress the accelerator pedal
further, activate kickdown or release the
brake pedal.
The braking action of PRE-SAFE ®
Brake is
ended automatically if:
R you drive slower than approximately
15 km/h.
R you manoeuvre 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 up to approximately 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 initially alert you both visually and acous-
tically. If you do not brake or take evasive
action, the system will warn you by automat-
ically braking the vehicle gently. If there is an
increased risk of collision, preventative
passenger protection measures (PRE-SAFE ®
)
are activated (Y page 43). If the risk of colli-
sion remains and you do not brake, take eva-
sive action or accelerate significantly, the
vehicle may perform automatic emergency
braking. Automatic emergency braking is not
performed until immediately prior to an acci-
dent that can no longer be avoided. G
WARNING
Even if PRE-SAFE ®
Brake slows the vehicle
before an imminent rear-end collision, the
system cannot avert a collision without the
intervention of the driver. There is a risk of an
accident. Brake according to the situation or
take evasive action. Delayed intervention by
the driver can lead to an accident. G
WARNING
PRE-SAFE ®
Brake cannot always clearly iden-
tify 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 par-
ticular 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 cover-
ing the sensors
R snow or heavy rain
R interference by other radar sources
R the possibility of strong radar reflections,
for example, in multi-storey car parks 60
