Exterior lighting
General notes
For reasons of safety, Mercedes-Benz recom-
mends that you drive with the lights switched on
even during the daytime. In some countries,
operation of the headlamps varies due to legal
requirements and self-imposed obligations.

Setting options
Exterior lighting can be set using:
Rthe light switch
Rthe combination switch (Ypage 116)

The exterior lighting (except the parking/stand-
ing lamps) switches off automatically if you:
Rremove the SmartKey from the ignition lock
Ropen the driver's door with the SmartKey in
position 0in the ignition lock
Automatic headlamp mode
à is the favored light switch setting. The light
setting is automatically selected according to
the brightness of the ambient light (exception:
poor visibility due to weather conditions such as
fog, snow or spray):
RSmartKey in position 1in the ignition lock: the
parking lamps are switched on or off auto-
matically depending on the brightness of the
ambient light.
RWith the engine running (USA only): if you
have switched on the Daytime Running
Lightsfunction in the on-board computer,
the daytime running lamps or the parking
lamps and low-beam headlamps are switched
on or off automatically depending on the
brightness of the ambient light.
XTo switch on automatic headlamp mode:
turn the light switch to Ã.
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 light-
ing at all times.

The daytime running lamps improve the visibility
of your vehicle during the day. The daytime run-ning lamps function is required by law in Can-
ada. 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 sta-
tionary 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 L, the manual settings take prec-
edence over the daytime running lamps.
USA only:
The daytime running lamps improve the visibility
of your vehicle during the day. To do this, the
daytime running lamps function must be
switched on using the on-board computer
(
Ypage 275).
If the engine is running and you turn the light
switch to TorL, the manual settings
take precedence over the daytime running
lamps.
Low-beam headlamps
Even if the light sensor does not detect that it is
dark, the parking lamps and low-beam head-
lamps switch on when the ignition is switched on
and the light switch is set to the Lposition.
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 ignition lock to posi- tion 2or start the engine.
XTurn the light switch to L.
The green Lindicator lamp in the instru-
ment cluster lights up.
Rear fog lamp
The rear fog lamp improves visibility of your
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.
XTo switch on the rear fog lamp: turn the
SmartKey in the ignition lock to position 2or
start the engine.
XTurn the light switch to LorÃ.
XPress the Rbutton.
The yellow Rindicator lamp in the instru-
ment cluster lights up.
XTo switch off the rear fog lamp: press the
R button.
The yellow Rindicator lamp in the instru-
ment cluster goes out.
Parking lamps
!If the battery has been excessively dis-
charged, the parking lamps or standing lamps
are automatically switched off to enable the
next engine start. Always park your vehicle
safely and sufficiently lit according to legal
standards. Avoid the continuous use of the
T parking lamps for several hours. If pos-
sible, switch on the Xright or the Wleft
standing lamp.
XTo switch on: turn the light switch to T.
The green Tindicator lamp in the instru-
ment cluster lights up.
Standing lamps
Switching on the standing lamps ensures the
corresponding side of the vehicle is illuminated.
XTo switch on the standing lamps: the
SmartKey should not be in the ignition lock or
it should be in position 0.
XTurn the light switch toW(left-hand side of
the vehicle) or X(right-hand side of the
vehicle).
Vehicles towing a trailer: both the right-hand
and left-hand standing lamps (tail lamps) are
always illuminated on the trailer.

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 con-
ditions.
In particular, the detection of obstacles can be
restricted if there is:
Rpoor visibility, e.g. due to fog, heavy rain or
snow
Rdirt on the sensors or the sensors are
obscured

The _ indicator lamp in the multifunction
display lights up when it is dark and the light
sensor activates the low-beam headlamps.
If you are driving at speeds above approx-
imately 16 mph (25 km/h):
The headlamp range is set automatically
depending on the distance between the vehi-
cle and other road users.
If you are driving at speeds above approx-
imately 19 mph (30 km/h) and no other road
users have been detected:
The high-beam headlamps are switched on
automatically. The Kindicator lamp in the
instrument cluster also lights up.
If you are driving at speeds below approx-
imately 16 mph (25 km/h) or other road users
have been detected or the roads are ade-
quately lit:
The high-beam headlamps are switched off
automatically. The Kindicator lamp in the
instrument cluster goes out. The _indi- cator lamp in the multifunction display
remains lit.
XTo switch off:
move the combination switch
back to its normal position or move the light
switch to another position.
The _ indicator lamp in the multifunction
display goes out.

Certain climatic and physical conditions may
cause moisture to form in the headlamp. This

This Operator's Manual describes all models
and all standard and optional equipment of
your vehicle available at the time of publica-
tion of the Operator's Manual. Country-spe-
cific differences are possible. Please note

Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up.
To prevent the windows from fogging up:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only briefly
Rswitch on the cooling with air dehumidifica-
tion function
Rswitch on the defrost windshield function
briefly, if required
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances out of the air.
For vehicles with a combustion engine, the
"Cooling with air dehumidification" function is
only available when the engine is running. For
hybrid vehicles, the "Cooling with air dehumidi-
fication" function is also available via the elec-
tric refrigerant compressor when the engine is
not running. Optimum climate control is only
achieved with the side windows and roof closed.
The residual heat function can only be activated
or deactivated with the ignition switched off
(
Ypage 138).
iVentilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (
Ypage 92).
This will speed up the cooling process and the
desired interior temperature will be reached
more quickly.
If you start the engine using your smartphone,
the last selected climate control setting is reac-
tivated (
Ypage 148).
iThe integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants
and odors. A clogged filter reduces the
amount of air supplied to the vehicle interior.
For this reason, you should always observe
the interval for replacing the filter, which is
specified in the Maintenance Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance Book- let.
iVehicles with AIR-BALANCE package: in
addition to ioniz ation, the vehicle has an air
filter with anti-allergenic properties that con-
tribute to improved air filtration.
iIt is possible that under certain circumstan-
ces the residual heat function may be activa-
ted automatically an hour after the SmartKey
has been removed in order to dry the auto-
matic climate control. The vehicle is then ven-
tilated for 30 minutes.
