2013 MERCEDES-BENZ GL-Class sensor

If Active Blind Spot Assist detects a risk of a
lateral collision in the monitoring range, a
course-correcting brake application is carried
out. This is meant to assist you in avoiding a
collision.
If a course-correcting brake application
occurs, red warning lamp 0002flashes in the
exterior mirror and a dual warning tone
sounds. In addition, display 0003appears in the
multifunction display.
The course-correcting brake application is
available in the speed range betwee n20m ph
(30 km/h) and120 mph (200km/h).
Either no braking application, or a course-
correcting brake application adapted to the
driving situation occurs if:
R there are vehicles or obstacles, e.g. crash
barriers, located on both sides of your
vehicle.
R a vehicle approaches you too closely at the
side.
R you have adopted a sporty driving style with
high cornering speeds.
R you clearly brake or accelerate. R
a driving safety system intervenes, e.g.
ESP ®
or PRE-SAFE ®
Brake.
R ESP ®
is switched off.
R the off-road program is activated (vehicles
without the ON&OFFROA Dpackage).
R off-road program 1 or 2 is activated
(vehicles with the ON&OFFROAD package).
R the LOW RANGE off-road gear is activated
