2015 MERCEDES-BENZ GLK-CLASS SUV low beam

Cornering light function
The cornering light function improves the illu-
mination of the road over a wide angle in the direction you are turning, enabling better vis-
ibility in tight bends, for example. The corner- ing light function can only be activated when
the low-beam headlamps are switched on.
Active: R if you are driving at speeds below 25 mph
(40 km/h) and switch on the turn signal or
turn the steering wheel
R if you are driving at speeds between
25 mph (40 km/h) and 45 mph (70 km/h)
and turn the steering wheel
The cornering lamp may remain lit for a short
time, but is automatically switched off after
no more than three minutes.
Adaptive Highbeam Assist
General notes
You can use this function to set the head-
lamps to change between low beam and high beam automatically. The system recognizes
vehicles with their lights on, either approach-
ing from the opposite direction or traveling in front of your vehicle, and consequently
switches the headlamps from high beam to
low beam.
The system automatically adapts the low-
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 high-beam headlamps. The system's optical sensor is located behind
the windshield near the overhead control
panel.
Important safety notes
GWARNING
Adaptive Highbeam Assist does not recognize road users:
R who have no lights, e.g. pedestrians
R who have poor lighting, e.g. cyclists
R whose lighting is blocked, e.g. by a barrier
In very rare cases, Adaptive Highbeam Assist
may fail to recognize other road users that
have lights, or may recognize them too late. In this or similar situations, the automatic high-
beam headlamps will not be deactivated or
activated regardless. There is a risk of an acci-
dent.
Always carefully observe the traffic conditions and switch off the high-beam headlamps in
good time.
Adaptive Highbeam Assist cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist is only an aid. You are responsible for adjusting the vehicle's
lighting to the prevailing light, visibility and
traffic conditions.

Other bulbs
GWARNING
Bulbs, lamps and connectors can get very hotwhen operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before changing a bulb.
Do not use a bulb that has been dropped or if
its glass tube has been scratched.
The bulb may explode if: R you touch it
R it is hot
R you drop it
R you scratch it
Only operate bulbs in enclosed lamps
designed for that purpose. Only install spare
bulbs of the same type and the specified volt- age.
Marks on the glass tube reduce the service
life of the bulbs. Do not touch the glass tube
with your bare hands. If necessary, clean the
glass tube when cold with alcohol or spirit and
rub it off with a lint-free cloth.
Protect bulbs from moisture during opera-
tion. Do not allow bulbs to come into contact
with liquids.
There are bulbs other than the Xenon bulbs
that you cannot replace. Replace only the
bulbs listed ( Y page 123). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop.
If you require assistance changing bulbs, con- sult a qualified specialist workshop.
If the new bulb still does not light up, consult
a qualified specialist workshop.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure that these function correctly at all times.
Have the headlamp setting checked regularly.
