WARNING
Active Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In these cases, Active Brake Assist may:
warn or brake for no reason
R
not issue a warning
R
not brake
R
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and do not rely on Active Brake Assist
alone. Be prepared to brake or manoeuvre if
necessary.
G
WARNING
The distance warning function does not react:
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
when cornering
R
The distance warning function may not give
warnings in all critical situations. There is a
risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
Always adapt your speed to suit the prevailing
road and traffic conditions.
G
WARNING
Severe jolting, for example in the case of a
collision, may cause the radar sensors to be
misaligned. The function of Active Brake
Assist is then impaired.
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
Have Active Brake Assist checked at a quali-
fied specialist workshop.
Driving systems and driving safety systems
Function of BAS (Brake Assist Sys-
tem)
G
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
If BAS is malfunctioning, the ÷ warning lamp
lights up while the engine is running
(
page 246) and the multifunction display
Y
shows a message (
BAS supports you with additional braking force
in an emergency braking situation.
If you depress the brake pedal quickly, BAS is
activated:
BAS automatically boosts the braking pres-
R
sure of the brakes.
BAS can shorten the braking distance.
R
ABS prevents the wheels from locking.

When you release the brake pedal, the brakes
function as usual again. BAS is deactivated.
Function of DSR (Downhill Speed Reg-
ulation)
G
If the speed driven and the target speed devi-
ate and you activate DSR on a slippery road
surface, the wheels may lose traction. There is
an increased risk of skidding and accidents.
Take the road surface and the difference
between the speed driven and the target
speed into account before activating DSR.
On vehicles with all-wheel drive, DSR can be
activated as assistance when driving downhill
off-road. The speed for DSR is not adjustable.
The target speed is 5 km/h in drive mode 4L and
is 8 km/h in drive mode 4H. DSR may not always
be able to keep to the target speed, depending
on the road surface and tyres.
If you fail to adapt your driving style, DSR can
neither reduce the risk of accident nor override
the laws of physics. It cannot take into account
road, weather or traffic conditions. DSR is only
