ESP MERCEDES-BENZ GLK SUV 2012 Owner's Manual

In these cases, PRE-SAFE
®
Brake may:
R give an unnecessary warning and then
brake the vehicle
R neither give a warning nor intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and be ready to brake, especially if
PRE-SAFE ®
Brake warns you. Terminate the
intervention in a non-critical driving situation.
In particular, the detection 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 radar sources
R the possibility of strong radar reflections,
for example, in multi-storey car parks
R a narrow vehicle travelling in front, e.g. a
motorcycle
R a vehicle travelling in front on a different
line G
WARNING
PRE-SAFE ®
Brake does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As a result, PRE-SAFE ®
Brake may neither
give warnings nor intervene in all critical sit-
uations. There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
In order to maintain the appropriate distance
to the vehicle in front and thus prevent a col-
lision, you must apply the brakes yourself.
X To activate/deactivate: activate or deac-
tivate PRE-SAFE ®
Brake in the on-board
computer (Y page 237).
When PRE-SAFE ®
Brake is activated, the
Ä symbol appears in the multifunction display, as long as the HOLD function is
deactivated (Y
page 186).
On vehicles with Parking Guidance, the
Ä symbol is displayed when Pis
engaged or you are driving faster than
35 km/h.
For PRE-SAFE ®
Brake to assist you when driv-
ing, the radar sensor system must:
R be switched on (Y page 242)
R be operational (Y page 272)
Vehicles with COMAND and a navigation sys-
tem: the radar sensor system is switched off
automatically in the vicinity of radio telescope
facilities (Y page 375).
Vehicles without COMAND and a navigation
system and vehicles for Australia: the radar
sensor system and on-board computer must
be switched off in the vicinity of radio tele-
scope facilities (Y page 242).
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensors checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at slow speeds where there is no visible
damage to the front of the vehicle. Anti-theft systems

G
WARNING
Adaptive Highbeam Assist is only an aid
designed to assist driving. The driver is
responsible for adjusting the vehicle's lighting
to the prevailing light, vision and traffic con-
ditions.
The system may be impaired or deactivated:
R if there is poor visibility, e.g. due to snow,
rain, fog or spray
R if the area of the windscreen around the
optical sensor is dirty, misted up or covered
up, e.g. by a sticker
The system may not recognise the following
road users:
R road users that have no lighting, e.g. pedes-
trians
R road users that have poor lighting, e.g.
cyclists
R road users whose lighting is not clearly visi-
ble, e.g. road users behind a crash barrier
R on rare occasions: road users that have
lights that may be recognised too late or not
at all
The automatic main-beam headlamps will not
be deactivated, or they may be activated
despite road users travelling in front of or
approaching the vehicle.
Thus, you could cause an accident and injure
yourself and others. Always observe traffic
conditions and, if necessary, dip the lights
manually.
You can use this function to set the head-
lamps to change between dipped beam and
main beam automatically. The system recog-
nises vehicles with their lights on, either
approaching from the opposite direction or
travelling in front of your vehicle, and conse- quently switches the headlamps from main
beam to dipped beam.
The system automatically adapts the dipped-
beam headlamp range depending on the dis-
tance to the other vehicle. Once the system
no longer detects any other vehicles, it reac-
tivates the main-beam headlamps.
The system's optical sensor is located behind
the windscreen near the overhead control
panel. X
To activate: activate the Adaptive High-
beam Assist function using the on-board
computer (Y page 240).
X Turn the light switch to Ã.
X Press the combination switch beyond the
pressure point in the direction of arrow :

If it is dark and the light sensor activates
the dipped-beam headlamps, the _
indicator lamp in the instrument cluster
lights up.
If you are driving at speeds above
45 km/h:
the headlamp range is set automatically

vehicle and other road users.

ognised: 116
