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 stationar yobstacles,
for example, stopped or parked vehicles.
Should yo uapproach an obstacl eand BAS
PLUS ha sdetected ariskofc ollision, BAS
PLUS calculates the braking force necessary
to avoid arear-en dcollision. Should you apply
the brakes forcefully,B AS PLUS can auto-
matically increase the braking force to alevel
suitable for the traffic conditions.
If BAS PLUS demands particularly high brak-
ing force, preventative passenger protection
measures (PRE-SAFE ®
)a re activated simul-
taneously.
X Keep the brake pedal depressed until the
emergenc ybraking situation is over.
ABS prevent sthe wheels from locking.
The brakes will work normally again if:
R you release the brake pedal.
R there is no longer any danger of arear-end
collision.
R no obstacle is detected in front of your
vehicle.
BAS PLUS is then deactivated.
The radar sensor system is switched off auto-
matically in the vicinit yofradio telescope
facilities (Y page 345).
Vehicles without COMAND and anavigation
system and vehicles for Australia: the radar
sensor system and on-board computer must
be switched off in the vicinit yofradio tele-
scope facilities (Y page 229).
For BAS PLUS to assist you when driving, the
radar sensor system must be switched on and
operational; see "Radar sensor system" in the
index. G
WARNING
BAS PLUS cannot alwaysc learly identify
object sand complex traffic situations. BAS
PLUS cannot intervene in these cases. There is
arisk 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 sno worh eavy rain
R interference by other radar sources
R the possibilit yofstrong radar reflections,
for example in multi-storey car parks
R an arrow vehicle travellin ginfront,e.g. a
motorbike
R av ehicle travellin ginfront on adifferent
line G
WARNING
BA SP LUS does not react:
R to people or animals
R to oncomin gvehicles
R to crossin gtraffic
R when cornering
As aresult ,BAS PLUS may not intervene in
critical situations .There is arisk 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 aqualified 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 BAS PLUS is not available due to amalfunc-
tion in the radar sensor system, the brake
system remains available with full brake
boosting effect and BAS. Adaptive brake lamps
i Adaptive brake lamps are only available in
certain countries.
If you brake sharply from aspeed of more
than 50 km/h or if braking is assisted by BAS Driving safety systems

passenger protection measures (PRE-SAFE
®
)
are activated (Y page 45). If the risk of colli-
sion remains and you do not brake, tak eeva-
sive action or accelerate significantly, the
vehicle may perfor mautomatic emergency
braking .Automatic emergenc ybraking is not
performed until immediately prio rtoanacci-
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 acollision without the
intervention of the driver. There is arisk 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 alwaysc learly iden-
tify object sand complex traffic conditions.
In these cases, PRE-SAFE ®
Brake may:
R give an unnecessary warning and then
brake the vehicle
R not give awarning or intervene
There is arisk of an accident .Always pay par-
ticular attention to the traffic situation and be
ready to brake, especially if PRE-SAFE ®
Brake
warns you. Terminat ethe intervention in a
non-critical drivin gsituation.
In particular, the detection of obstacles can
be impaired if there is:
R dirt on the sensors or anything else cover-
ing the sensors

Important safety notes
G
WARNING
The seats can still be adjusted when there is
no key in the ignition lock. For this reason,
children should never be left unsupervised in
the vehicle. They could adjust the seats and
become trapped. G
WARNING
Only adjust the driver's seat when the vehicle
is stationary. You will otherwise be distracted
from the road and traffic conditions and you
could lose control of the vehicle as aresult of
the seat moving. This could cause an acci-
dent. G
WARNING
If you adjust the seat height carelessly, you or
others could be trapped and thereby injured.
Children in particular could unintentionally
press the button stoelectrically adjust the
seats and become trapped.
Take care that:
R while moving the seats, your hands do not
get under the lever assembly of the seat
adjustmen tsystem.
R children in th evehicl edon ot slide their
hands under the levers. G
WARNING
Make sure that nobody can becom etrapped
when adjusting the seats.
Observe the notes on airbags.
Secure children as recommended; see the
"Children in the vehicle" section. G
WARNING
Make sure that the back of your head is sup-
ported at eye level by the central area of the
head restraint .Ifyour head is not supported
correctly by the head restraint ,you could suf-
fer asevere neck injury in the event of an
accident .Never drive if the head restraints are
not engaged and set correctly. G
WARNING
As eat belt can only offer its intended degree
of protection when the backrest is almost ver-
tical and the occupant is sitting upright. Avoid
seat position sthat do not allow the seat belt
to be routed correctly. Adjust the backrest so
that it is as upright as possible. Never travel
with the backrest reclined too far backwards.
You could otherwise be seriously or even
fatally injured in the event of an acciden tor
sudden braking.
! To avoid damage to the seats and the seat
heating, observe the following information:
R do not spill any liquids on the seats. If
liquid is spilled on the seats, dry them as
soon as possible.
R if the seat cover sare damp or wet, do not
switch on the seat heating. The seat
heating should also not be used to dry
the seats.
R clean the seat cover sasrecommended;
see the "Interior care" section.
R do not transport heavy loads on the
seats. Do not place sharp objects on the
seat cushions ,e.g. knives, nails or tools.
The seats should only be occupied by
passengers, if possible.

G
WARNING
The electrically adjustable steering wheel can
still be adjusted when there is no key in the
ignition lock. Therefore, do not leave children
unsupervised in the vehicle, as they could
become trapped if the steering wheel is adjus-
ted. G
WARNING
Only adjust the steering wheel when the vehi-
cle is stationary and do not pull away until the
steering wheel adjustment mechanism is
locked in position. You might otherwise drive
without the steering wheel adjustment mech-
anism being locked in position. As aresult,
you could be distracted from road and traffic

The system may be impaired or deactivated:
R
if there is poor visibility, e.g. due to snow,
rain, fog or spray
R if the area of the windscreen around the
optical sensor is dirty, misted up or covered
up, e.g. by asticker
The system may not recognise the following
road users:
R road users that have no lighting, e.g. pedes-
trians
R road users that have poor lighting, e.g.
cyclists
R road users whose lighting is not clearly visi-
ble, e.g. road users behind acrash barrier
R on rare occasions :road users that have
lights that may be recognised too late or not
at all
The automatic main-beam headlamps will not
be deactivated, or they may be activated
despite road users travelling in front of or
approaching the vehicle.
Thus, you could cause an accident and injure
yourself and others. Always observe traffic
conditions and, if necessary, dip the lights
manually. Headlamps misted up inside
The headlamps may mist up on the inside if
there is high atmospheric humidity.
X Drive with the headlamps switched on.
The level of moisture diminishes, depend-
ing on the length of the journey and the
weather conditions (humidity and temper-
ature).
If the level of moisture does not diminish:

will speed up the cooling process and the
desired vehicle interior temperature will be
reached more quickly.
i The integrated filter can filter out most
particles of dust and completely filters out
pollen. Aclogged filter reduces the amount
of air supplied to the vehicle interior .For
this reason, you should always observe the interval for replacing the filter, which is
specified in the Servic
