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.
RWith the engine running (Canada only):
depending on the ambient light, the day-
time running lamps or the parking lamps
and the low-beam headlamps are switched
on or off automatically.
XTo switch on the automatic headlamps:
turn the light switch to the Ãposition.
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.
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 2
or start the engine.
XTurn the light switch to the LorÃ
position.
XPress the Rbutton.
The yellow Rindicator lamp in the
instrument cluster lights up.
XTo switch off the rear fog lamp: press the
R button.
The yellow Rindicator lamp in the
instrument cluster goes out.

Hazard warning lamps
XTo switch on the hazard warning lamps:press button :.
All turn signals flash. If you now switch on a
turn signal using the combination switch,
only the turn signal lamp on the corre-
sponding side of the vehicle will flash.
XTo switch off the hazard warning lamps:
press button :.
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

Z

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:
Rwho have no lights, e.g. pedestrians
Rwho have poor lighting, e.g. cyclists
Rwhose 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. Youare 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:
Rpoor visibility, e.g. due to fog, heavy rain or
snow
Rdirt on the sensors or the sensors are
obscured
Switching Adaptive Highbeam Assist
on/off
XTo switch on: turn the light switch to Ã.
XPress the combination switch beyond the
pressure point in the direction of arrow :.
The _ indicator lamp in the multifunc-
tion display lights up if it is dark and the
light sensor activates the low-beam head-
lamps.
If you are driving at speeds above 25 km/h:
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
vehicle 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
adequately lit:
The high-beam headlamps are switched off
automatically. The Kindicator lamp in
the instrument cluster goes out. The _
indicator 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 instrument
cluster goes out.
Headlamps fogged up on the inside
Certain climatic and physical conditions may
cause moisture to form in the headlamp. This
moisture does not affect the functionality of
the headlamp.

Replacing bulbs
Important safety notes
GWARNING
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:
Ryou touch it
Rit is hot
Ryou drop it
Ryou 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.
Only replace the bulbs listed (
Ypage 130).
Have the bulbs that you cannot replace your- self replaced at a qualified specialist work-
shop.
If you require assistance replacing bulbs, con-
sult a qualified specialist workshop.
If the new bulb still does not light up, consult
a qualified specialist workshop.
Headlamps and lights are an important
aspect of vehicle safety. You must therefore
make sure that these function correctly at all
times. Have the headlamp setting ch ecked
r

egularly.
Vehicles with LED headlamps: the front
and rear light clusters of your vehicle are
equipped with LED light bulbs. Do not replace the bulbs yourself. Contact a qualified spe-
cialist workshop which has the necessary
specialist knowledge and tools to carry out
the work required.
