Useful information
i This Operator's manual describes all
models and all standard and optional equip- ment of your vehicle available at the time of
publication of the Operator's manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.
i Read the information on qualified special-
ist workshops (Y page 26). Exterior lighting
General notes
For reasons of safety, Mercedes-Benz recom- mends that you drive with the lights switchedon even during the daytime. In some coun-
tries, operation of the headlamps varies due
to legal requirements and self-imposed obli-
gations. Driving abroad
Conversion to symmetrical low beam Switch the headlamps to symmetrical low
beam in countries in which traffic drives on
the opposite side of the road from the country
where the vehicle is registered. This prevents glare to oncoming traffic. When using sym-
metrical lights, the edge of the road is not lit
as widely and as far ahead as normal.
Have the headlamps converted at a qualified
specialist workshop as close to the border as
possible before driving in these countries.
Conversion to asymmetrical low beam
after returning Have the headlamps converted back to asym-
metrical low-beam headlamps at a qualified
specialist workshop as soon as possible after crossing the border again. Setting the exterior lighting

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.
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.
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.
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
0058 position. This is a particularly useful
function in the event of rain and fog.
X To switch on the low-beam headlamps:
turn the SmartKey in the ignition lock to
position 2or start the engine.
X Turn the light switch to 0058.
The green 0058indicator lamp in the instru-
ment cluster lights up.

fog, snow or rain, the fog lamps improve vis-
ibility as well as making it easier for other road
users to see you. They can be operated
together with the parking lamps or together
with the parking lamps and low-beam head-
lamps.
X To switch on the front fog lamps: turn
the SmartKey in the ignition lock to position 2 or start the engine.
X Turn the light switch to 0058or0058.

The yellow 005Eindicator lamp in the
instrument cluster goes out.
i When the rear fog lamp is switched on,
the center brake lamp in the tail lamp
switches off due to a legal requirement.
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

sponding side of the vehicle will flash.
X To switch off the hazard warning lamps:
press button 0043.
The hazard warning lamps switch off auto-
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
Not active: if you are driving at speeds above
45 mph (70 km/h) or switch off the turn sig-
nal 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. Exterior lighting
111Lights and windshield wipers Z

Extended range fog lamps
The extended range fog lamps reduce the
glare experienced by the driver and improve
the illumination of the edge of the road.
Active: if you are driving at speeds below
40 mph (70 km/h) and you switch on the rear
fog lamp.
Not active: if, following activation, you are
driving at speeds above 60 mph (100 km/h)
or if you switch off the rear fog lamp. 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. 112
