WARNING
The distance warning function does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
Thus ,the distance warning function cannot
provid eawarning in all critical situations.
There is arisk of an accident.
Always pay carefu lattention to the traffic sit-
uation and be read ytobrake. G
WARNING
The distance warning function cannot always
clearly identify objects and comple xtraffic
situations.
In such cases, the distance warning function
may:
R give an unnecessary warning
R not give awarning
There is arisk of an accident.
Always pay carefu lattention to the traffic sit-
uation; do not rely on the distance warning
function alone.
Function The distance warning function issues awarning
at speeds:
R of approximately 30 km/h or more, if, over
severa lseconds, the distance maintained to
the vehicl etravelling in front is insufficient.
The · distance warning lamp then lights
up in the instrument cluster.
R of approximately 7km/h or more, if you rap-
idlya pproach avehicl einf ront. An intermit-
tent warning tone willt hen sound,and the
· distance warning lamp willl ight up in the
instrument cluster.
X Brake immediatel yinorder to increas ethe
distance from the vehicl einfront.
or
X Take evasive action provided it is safe to do
so.
Due to the nature of the system, particularly
complicated but non-critical driving conditions
may alsoc ausethe system to display awarning. With the help of the rada
rsensor system, the
distance warning function can detect obstacles
that are in the path of yourv ehiclefor an exten-
ded period of time.
Up to aspee dofa pproximatel y70k m/h, the
distance warning function can alsor eact to sta-
tionary obstacles, such as stoppe dorparked
vehicles.
Autonomous braking function If the drive
rdoes not react to the distance warn-
ing signa linacritical situation, COLLISION PRE-
VENTION ASSIST PLUS can assist with the
autonomous braking function.
The autonomous braking function:
R gives the drive rmore time to react to critical
driving situations
R can help the drive rtoavoidana ccident or
R reduces the effects of an accident
Vehicles without DISTRONIC PLUS: the
autonomous braking function is available in the
following spee dranges:
R 7-1 05 km/h for moving objects
R 7-50k m/h for stationary objects
Vehicles with DISTRONIC PLUS: the autono-
mous braking function is available in the follow-
ing spee dranges:
R 7-2 00 km/h for moving objects
R 7-50k m/h for stationary objects
Due to the nature of the system, complicated
but non-critical driving situations may also
caus ethe autonomous braking function to inter-
vene.
If the autonomous braking function demands
particularl yhigh braking force, preventative
passenger protection measures (PRE-SAFE ®
)
are activated simultaneously (Y page54).
Adaptive Brake Assist General notes
i Observe the "Important safety notes" sec-
tion (Y page66).
With the help of Adaptive Brake Assist, the dis-
tance warning signa lcan detect obstacles that
are in the path of yourv ehiclefor an extended
period of time.
If Adaptive Brake Assist detects arisk of acol-
lision with the vehicl einfront, it calculates the 70

you apply the brakes forcefully, Adaptiv eBrake
Assist will automatically increase the braking

Adaptiv eBrakeA ssist provides brakin gassis-
tanc einh azardous situation satspeeds above
7k m/h. It uses radar sensor technology to
assess the traffic situation.
Up to aspeed of approximately 250 km/h,
Adaptiv eBrakeA ssist is capable of reacting to
movin gobjects that have already been detected
as such at least onc eover the period of obser-
vation.
Up to aspeed of approximately 70 km/h, Adap-
tive Brak eAssist react stostationary obstacles.
If Adaptiv eBrakeA ssist demands particularly
high brakin gforce, preventativ epassenger pro-
tection measures (PRE-SAFE ®
)a re activated
simultaneously (Y page 54).
X Keep the brake pedal depressed until the
emergency brakin gsituation is over.
ABSp revents the wheels from locking.
The brakes will work normally again if: R you release the brake pedal
R ther eisnol onger any danger of acollision
R no obstacle is detected in fron tofyour vehicle
Adaptiv eBrakeA ssist is then deactivated.

WARNING
Adaptiv eBrakeA ssist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptiv eBrakeA ssist can:
R interven eunnecessarily
R not intervene
There is arisk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. Terminate the
intervention in anon-critical driving situation. G
WARNING
Adaptiv eBrakeA ssist does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As aresult, the Adaptiv eBrak eAssist may not
interven einall critical conditions. There is a
risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake.
Due to the natur eofthe system, particularly
complicated but non-critical driving conditions
may also cause Brak eAssist to intervene.
If Adaptiv eBrak eAssist is not available due to a
malfunction in the radar sensor system, the
brake system remains available with full brake
boostin geffec tand BAS. Adaptive brake lights
The adaptive brake lights warn following traffic
in an emergency brakin gsituation:
R by flashing brake lamps
R by activating the hazard warning lamps
If you brake sharply from aspeed of more than
50 km/ horifb raking is assisted by BAS or BAS
PLUS, the brake lamp sflashr apidly.Int his way,
traffic travelling behind you is warned in an even more noticeable manner.
If you brake sharply from aspee dofm ore than
