MERCEDES-BENZ SLK-Class 2015 R172 Owner's Manual

Automatic headlamp mode
G
WARNING
When the light switch is set to 0058, the low-
beam headlamps may not be switched on
automatically if there is fog, snow or other
causes of poor visibility due to the weather
conditions such as spray. There is a risk of an
accident.
In such situations, turn the light switch to
0058.
The automatic headlamp feature is only an
aid. The driver is responsible for the vehicle's lighting at all times.
0058 is the favored light switch setting. The
light setting is automatically selected accord- ing to the brightness of the ambient light
(exception: poor visibility due to weather con-
ditions such as fog, snow or spray):
R SmartKey in position 1in the ignition lock:
the parking lamps are switched on or off
automatically depending on the brightness of the ambient light.
R With the engine running: if you have acti-
vated the daytime running lamps function
via the on-board computer, the daytime
running lamps or the low-beam headlamps
and parking lamps are switched on or off
automatically depending on the brightnessof the ambient light.
X To switch on automatic headlamp
mode: turn the light switch to 0058.
Only for Canada:
The daytime running lamps improve the visi-
bility of your vehicle during the day. The day-
time running lamps function is required by law in Canada. It cannot therefore be deactivated.
When the engine is running and the vehicle is
stationary: if you move the selector lever from
a drive position to P, the daytime running
lamps/low-beam headlamps go out after
three minutes.
When the engine is running, the vehicle is
stationary and in bright ambient light: if you turn the light switch to
0060, the daytime
running lamps and parking lamps switch on.
If the engine is running and you turn the light switch to 0058, the manual settings take
precedence over the daytime running lamps.
USA only:
The daytime running lamps improve the visi-
bility of your vehicle during the day. To do this,
the daytime running lamps function must be
switched on using the on-board computer
(Y page 205).
If the engine is running and you turn the light
switch to 0060or0058, the manual settings
take precedence over the daytime running
lamps.

matically 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 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 Exterior lighting
111Lights and windshield wipers Z

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 steer-
ing movements of the front wheels. In this
way, relevant areas remain illuminated while
driving. This allows you to identify pedes-
trians, cyclists and animals.
Active: when the lights are switched on. 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 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 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.
In particular, the detection of obstacles can
be restricted if there is:
R poor visibility, e.g. due to fog, heavy rain or
snow
R dirt on the sensors or the sensors are
obscured 112

Important safety notes
Xenon bulbs G
DANGER
Xenon bulbs carry a high voltage. You can get an electric shock if you remove the cover of
the Xenon bulb and touch the electrical con-
tacts. There is a risk of fatal injury.
Never touch the parts or the electrical con-
tacts of the Xenon bulb. Always have work on
the Xenon bulbs carried out at a qualified spe-
cialist workshop. If your vehicle is equipped with Xenon bulbs,
you can recognize this by the following: the
cone of light from the Xenon bulbs moves
from the top to the bottom and back again
when you start the engine. For this to be
observed, the lights must be switched on
before starting the engine.
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.
Other bulbs 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.
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 115). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop. 114

Switching the windshield wipers
on/off
! Do not operate the windshield wipers
when the windshield is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windshield can
scratch the glass if wiping takes place when the windshield is dry.
If it is necessary to switch on the windshield wipers in dry weather conditions, always
use washer fluid when operating the wind-
shield wipers.
! If the windshield wipers leave smears on
the windshield after the vehicle has been
washed in an automatic car wash, wax or
other residues may be the reason for this.
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

wiping frequency is set automatically accord-
ing to the intensity of the rain. In the 0063
position, the rain sensor is more sensitive
than in the 0062position, causing the wind-
shield 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 condi-
tions, thereby causing an accident. 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 wind-
shield.
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 a qualified
specialist workshop.
! Always position the windshield wiper
arms vertically before folding them away
from the windshield. By doing so, you will
avoid damage to the hood.
