The hazard warning lamps automatically
switch on if:
R
an air bag is deployed
R the vehicle decelerates rapidly from a
speed of above 45 mph (70 km/h) and
comes to a standstill
The hazard warning lamps switch off
automatically if the vehicle reaches a speed
of above 6 mph (10 km/h) again after a full
brake application.
i The hazard warning lamps still operate if
the ignition is switched off. Cornering light function
The cornering light function improves the
illumination of the road over a wide angle in
the direction you are turning, enabling better
visibility in tight bends, for example. It 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 tur nsignal or
tur nthe 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
Not active: if you are driving at speeds above
25 mph (40 km/h) or switch off the turn
signal or turn the steering wheel to the
straight-ahead position. The cornering lamp may remain lit for a short
time, but is automatically switched off after
no more than three minutes. Active light function
The active light function is a system that
moves the headlamps according to the
steering movements of the front wheels. In
this way, relevant areas remain illuminated
while driving. This allows you to identify
pedestrians, cyclists and animals.
Active: whenthe lights are switched on. Adaptive Highbeam Assist
Important safety notes G
WARNING
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
accident.
Always carefully observe the traffic conditions
and switch off the high-beam headlamps in
good time. Exterior lighting

Important safety notes
G
WARNING
Bulbs, lamps and connectors can get very hot
when 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.
Vehicles with static LED headlamps:
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
voltage.
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.
Protec tbulbs from moisture during
operation .Do not allow bulbs to come into
contact with liquids.
Replace only the bulbs listed (Y page 143).
Have the bulbs that you cannot replace 142

Clean the windshield using washer fluid
after washing the vehicle in an automatic
car wash.
! Intermittent wiping with rain sensor: due
to optical influences and the windshield
becoming dirty in dry weather conditions,
the windshield wipers may be activated
inadvertently. This could then damage the
windshield wiper blades or scratch the
windshield.
For this reason, you should always switch
off the windshield wipers in dry weather. Combination switch

In the 0001or0002 position, the appropriate
wiping frequency is set automatically
according to the intensity of the rain. In
the 0002 position, the rain sensor is more
sensitive than in the 0001position, causing
the windshield wipers to wipe more
frequently. If the wiper blades are worn, the windshield
will no longer be wiped properly. This could
prevent you from observing the traffic
conditions. Replace the wiper blades twice a
year, ideally in spring and fall.
Replacing the wiper blades
Important safety notes G
WARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you could
be trapped by the wiper arm. There is a risk
of injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
! To avoid damaging the wiper blades,
make sure that you touch only the wiper
arm of the wiper.
! Never open the hood if a windshield wiper
arm has been folded away from the
windshield.
Never fold a windshield wiper arm without
a wiper blade back onto the windshield.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release
the windshield wiper arm without a wiper
blade and it falls onto the windshield, the
windshield may be damaged by the force of
the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at aqualified
specialist workshop.
