R
a driving safety system intervenes, such as
ABS, BAS or ESP
®
.

tion occurs if:
R

a driving safety system intervenes, e.g. ABS,
BAS or ESP
®
.
R
you accelerate hard, e.g. kickdown.
R
you brake hard.
R
you steer actively, e.g. swerve to avoid an
obstacle or change lanes quickly.
R
you cut the corner on a sharp bend.
In order that you are warned only when neces-
sary and in good time if you cross the lane mark-

and warns you accordingly.
The warning vibration occurs earlier if:
R
you approach the outer lane marking on a
bend.

Active Driving Assistance package
General notes
The Active Driving Assistance package consists
of DISTRONIC PLUS (
Y page 155), Active Blind
Spot Assist (
Y page 190) and Active Lane Keep-
ing Assist (
Y page 193).
Active Blind Spot Assist
General notes
Active Blind Spot Assist uses a radar sensor
system, pointed toward the rear of the vehicle,
to monitor the area to the sides of the vehicle
which the driver is unable to see. A warning dis-
play in the exterior mirrors draws your attention
to vehicles detected in the monitored area. If
you then switch on the corresponding turn sig-
nal to change lane, you will also receive an opti-
cal and audible warning. If a risk of lateral colli-
sion is detected, corrective braking may help
you avoid a collision. Before a course-correcting
brake application, Active Blind Spot Assist eval-
uates the space in the direction of travel and at
the sides of the vehicle. For this, Active Blind
Spot Assist uses the forward-facing radar sen-
sors.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (30 km/h).
Important safety notes
Active Blind Spot Assist is only an aid and is not
a substitute for attentive driving.
G
WARNING
Active Blind Spot Assist does not react to:
R
vehicles overtaken too closely on the side,
placing them in the blind spot area
R
vehicles which approach with a large speed
differential and overtake your vehicle
As a result, Active Blind Spot Assist may nei-
ther give warnings nor intervene in such sit-
uations. There is a risk of an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.
