WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased .There is arisk of accident.
In an emergenc ybraking situa tion, depress
the bra kepedal with full force. AB Sprevents
th ew heels fr om locking.
BAS operate sinemergency brakin gsitua-
tions. If you depress the brake pedal quickly,
BAS automatically boosts the brakin gforce,
thus shortening the stoppin gdistance.
The brakes will func tion as usual onc eyou
release the brake pedal. BA Sisd eactivated. BAS PLUS (Brake Assist Syste
mPlus)
i Observe the "Importan tsafety notes" sec-
tion (Y page 61).
BAS PLUS is only available on vehicles with
DISTRONIC PLUS.
BAS PLUS provides braking assistance in haz-
ardous situations at speeds greater than
7k m/h and uses rad ar sensortechnology to
assess the traffic situation.
With the help of the rada rsensor system ,BAS
PLU Scan 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 det ects tationar yobstacles,
for example, stopped or parked vehicles.
To prevent afront-en dcollision, BA SPLUS
calculate sthe brake force necessary if:
R you approach an obstacle, and
R BA SP LUS ha sdetected arisk of collision
If you ar edriving at aspeed over
30 km/h:ify ou depress the brake sharply,
BA SP LUS automatically raise sthe brake
pressur etoavalue adapted to the traffic sit-
uation. If you are driving at
aspeed under
30 km/h:ify ou depress the brake, BA SPLUS
is activated. Braking will be carried ou tatthe
last possible moment.
If BA SPLUS demand sparticularly high brak-
ing force, preventative passenger protection
measures (PRE-SAFE ®
)a re activate dsimul-
taneously.
X Keep the brake pedal depressed until the
emergenc ybraking situatio niso ver.
ABS prevents th ewheels from locking.
BA SP LUS is deactivate dand the brakes func-
tion as usual ,if:
R you release th ebrake pedal.
R there is no longe rany danger of arear-end
collision.
R no obstacl eisdetected in front of your
vehicle.
If you have activated DSR (Y page 251), BAS
PLU Sisa lso deactivated.
The radar sensor system is switched off auto-
matically in the vicinit yofradio telescope
facilities in the following vehicles:
R vehicles with COMAND Online and naviga-
tion

As aresult, Adaptive Br akeA ssist may not
int ervene in al lcritica lconditions .There is a
risk of an accident.
Always pay carefu lattention to the traffic sit-
uation and be ready to brake.
Adaptive Brake Assist aids you in braking dur-
ing hazardous situations at speeds above
30 km/h and uses the radar sensor system
to evaluate the traffic situation.
With the hel pofthe adaptive Brake Assist ,the
distanc ewarning signal can detect obstacles
that are in the path of your vehicle for an
extended period of time.
Should you approach an obstacle and the
adaptive Brake Assis thas detected arisk of
collision, the adaptive Brake Assist calculates
the brakin gforc enecessar ytoavoidac olli-
sion with the vehicle in front .Should you
apply the brakes forcefully ,the adaptive
Brake Assist will automatically increase the
brakin gforc etoal evel suitable for the traffic
conditions.
X Keep the brak epedal 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 brak epedal.
R there is no longer any danger of arear-end
collision.
R no obstacl eisdetected in front of your
vehicle.
Adaptive Brake Assist is then deactivated.
If adaptive Brake Assist demands particularly
high braking force, preventative passenger
protec tion measure s(PRE-SAFE ®
)a re activa-
ted simultaneousl y.
Up to vehicl espeeds of around 25 0km/h,
th ea daptiv eBrake Assist is capable of react-
ing to moving objects that have alread ybeen
recognised as such at least once over the
period of observation .Adaptiv eBrake Assist
does not react to stationary obstacles. If th
eadaptiv eBrake Assist is not available
du et oam alfunction in the radar senso rsys-
tem, the brake syste mremains available with
ful lbrake boostin geffect and BAS.
In particular, th edetection 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 rada rsources
R the possibility of stron gradar reflections,
for example, in multi-storey car parks
R an arrow vehicle travelling in front ,e.g. a
motorcycle
R av ehicle travelling in front on adifferent
line
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensor 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. Adaptive brake lamps
If you brake sharply from aspeed of more
than 50 km/ horifbraking is assisted by BAS
or BAS PLUS, th ebrake lamp sflash rapidly.
In this way, traffic travelling behind you is
warned in an even more noticeable manner.
If you brake sharply from aspeed of more
than 70 km/ htoastandstill, the hazard warn-
ing lamps are activated automatically .Ifthe
brakes ar eapplied again, the brak elamps
light up continuously .The hazard warning
lamps switc hoff automatically if you travel
faster than 10 km/h .You can also switc hoff
th eh azard warning lamps using the hazard
warning button (Y page 122). Driving safety systems
