daytime running lamps or the parking
lamps and the low-beam headlamps are
switched on or off automatically depending
on the brightness of the ambient light.

depending on the ambient light, the day-
time running lamps or the parking lamps
and the low-beam headlamps are switched

GWARNING
When the light switch is set to Ã, 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
L.
The automatic headlamp feature is only an
aid. The driver is responsible for the vehicle's
lighting at all times.
Canada only:
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 T, the daytime
running lamps and parking lamps switch on.
If the engine is running and you turn the light
switch to the Lposition, the manual set-
tings take precedence over the daytime run-
ning 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
(
Ypage 255).
If the engine is running and you turn the light
switch to the TorL position, the man-
ual settings take precedence over the day-
time running lamps.
Low-beam headlamps
Even if the light sensor does not detect that it
is dark, the parking lamps and low-beam
headlamps switch on when the ignition is
switched on and the light switch is set to the
L position. This is a particularly useful
function in the event of rain and fog.
XTo switch on the low-beam headlamps:
turn the SmartKey in the ign
ition lock to
position 2or start the engine.
XTurn the light switch to the Lposition.
The green Lindicator lamp in the instru-
ment cluster lights up.

vehicle for the traffic behind in the event of
thick fog. Please take note of the country-
specific regulations for the use of rear fog
lamps.

SmartKey in the ignition lock to position 2
or start the engine.

turn signal using the combination switch,
only the turn signal lamp on the corre-
sponding side of the vehicle will flash.

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. It can only
be activated when the low-beam headlamps
are switched on. Active:
Rif you are driving at speeds below 25 mph
(40 km/h) and switch on the turn signal or
turn the steering wheel
Rif 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.
Cornering light function with traffic circle
function:
The cornering light function is activated on
both sides before entering a traffic circle
through an evaluation of the current GPS
position of the vehicle. It remains active until after the vehicle has left the traffic circle. In
this way, pedestrians crossing the road, for
example, are illuminated by your vehicle in
good time.
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

Windshield wipers
Switching the windshield wiper
on/off
!
Do not operate the windshield wipers
when the windshield isdry, as this could
damage the wiperblades. Moreover, dust
that has co llected 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
wiper sin dry weather conditions, always
use washer fluid when operating the wind-
shield wiper s.
!Ifthe windshield wipers leave smears on
the windshield after the vehicle has been
washed inan automat iccar wash, wax or
other residues may bethe reason for this.
Clean the windshield using washer fluid
after washing the vehicle inan automat ic
car wash.
!In term ittent wiping with rain sensor: due
to optical influences and the windshield
becoming dirtyin dry weather conditions,
the windshield wipers may beactivated
inadvertently. This could then damage the
win dshield wiper blades or scratch the
win dshield.
For th isreason, you should always switch
off the windshield wipersin dry weather.

Vehicles with a rain sensor: inthe Ä or
Å position, the appropriate wiping fre-
quency isautomatical lyset according to the
intensity of the rain. Inthe Å position, the
rain sensor ismore sensitive thaninthe Ä
position, causing the windshield wiper to wipe
more frequently.
If the wiper bladesare worn, the windshield
will no longer bewiped properly. This could
prevent you from observing the traff iccond i-
tions.

Important safety notes
GWARNING
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.
!Never open the hood/tailgate if a wiper
arm has been folded away from the wind-
shield/rear window.
Never fold a windshield wiper arm without a
wiper blade back onto the windshield/rear
window.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release the wiper arm without a wiper blade and it
falls onto the windshield/rear window, the
windshield/rear window may be damaged
by the force of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified
specialist workshop.
!To avoid damaging the wiper blades,
make sure that you touch only the wiper
arm of the wiper.
