If you fail to adapt your driving style or if you
are inattentive, th edriving safety systems can
neither reduc ethe riskofana ccidentnor
override th elaws of physics. Drivin gsafety
systems are merely aids designe dtoassist
driving .You are responsible for maintaining
th ed istanc etothevehicle in front, for vehicle
speed, for braking in good time, and for stay- ing in lane .Always adapt your driving style to
suit th eprevailin groad and weather condi-
tions and maintain asafe distanc efromt he
vehicle in front. Drive carefully.
The driving safety systems describe donly
work as effectivel yaspossible when there is
adequat econtac tbetween th etyres and the
road surface. Pleas epay special attentio nto
th en otes on tyres, recommended minimum
tyr etread depths etc. (Y page 416).
In wintry driving conditions, always use winter
tyres (M+ Styres) and ,ifnecessary, snow
chains .Onlyint hisw ay will th edriving safety
systems describe dinthiss ectio nwork as

When driving at
aspee dabove 30 km/h :if
you depress the brake peda lsharply,B AS
PLUS automatically increases the brake pres- sure to adegre esuited to the traffic situation.
BAS PLUS provides braking assistance in haz- ardous situations with vehicles in front within
as pee drange between 7km/h and
250 km/h.
Up to aspee dofa pproximately 70 km/h, BAS
PLUS may react to:
R stationary objects in the path of yourv ehi-
cle, e.g. stoppe dorparked vehicles
R pedestrians in the path of yourv ehicle
R obstacles crossing yourp ath, which move
in the detection range of the sensors and
are recognised by them
i If BAS PLUS demands particularly high
braking force, preventative passenger pro-
tection measures (PRE-SAFE ®
)a re activa-
ted simultaneously.
X Keep the brake peda ldepressed 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 arisk of collision
R no obstacl eisdetected in front of your
vehicle
R you depress the accelerator pedal
R you activate kickdown COLLISIONP
REVENTIONASSIST
PLUS
General notes COLLISION PREVENTIO
NASSIST PLUS con-
sists of adistance warning function with an
autonomous braking function and Adaptive
Brake Assist.
COLLISION PREVENTIO NASSIST PLUS can
help you to minimise the risk of acollision with the vehicl
einfront or reduce the effects
of such acollision.
If COLLISION PREVENTIO NASSIST PLUS
detects that there is arisk of acollision, you
willbew arned visuallya nd acoustically.Ify ou
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 acritical situation, the COLLISION
PREVENTIO NASSIST PLUS Adaptive Brake
Assist assists you.
Switchin gthe soun don/off COLLISION PREVENTIO
NASSIST PLUS is
activated after every ignition cycle .You can
activate or deactivate COLLISION PREVEN-
TION ASSIST PLUS in the on-board computer
(Y page2 87). When deactivated, the dis-
tance warning function and the autonomous
braking function are alsod eactivated.
If COLLISION PREVENTIO NASSIST PLUS is
deactivated, the æsymbol appears in the
assistance graphics display.
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 rada rsources
R strong rada rreflections, for example, in
multi-storey car parks
R an arrow vehicl etravelling in front, e.g. a
motorcycle
R av ehicl etravelling in front on adifferent
line
R new vehicles or after aservice on the COL-
LISION PREVENTIO NASSIST PLUS system
Please observe the information in the sec-
tion on running-in the vehicle
