Useful information
This Operator's Manual describes all models
as well as standard and optional equipment of your vehicle that were available at the time of going to print. Country-specific variations are
possible. Note that your vehicle may not be
equipped with all of the described functions.
This also applies to systems and functions
relevant to safety.
Read the information on qualified specialist
workshops (Y page 25). Exterior lighting
Important safety notes
For reasons of safety, we recommend that
you drive with the lights switched on even
during the daytime. There may be differences
in operation due to legal requirements and
voluntary recommendations in some coun-
tries. Bulb failure indicator
The bulb failure indicator is only an aid. You
are responsible for the proper functioning of
the vehicle lighting. Insufficient or non-func-
tioning vehicle lighting puts the operating
safety of the vehicle at risk.
For this reason, check the condition and func-
tion of your vehicle's lighting system and, if
necessary, that of the trailer before each jour- ney.
The bulb failure indicator monitors all of the
exterior lighting lamps, except the perimeter
lamp and the trailer lighting. If a bulb fails,
either the 0049(Ypage 35) indicator lamp
lights up, or you will see a corresponding
message in the display (Y page 208).
i Depending on the equipment, the bulb
failure indicator can fail for all lamps with
the exception of the turn signal lamps. Light switch

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.
Automatic headlamp mode is only a driving
aid. You are responsible for the vehicle light-
ing at all times.
Depending on ambient light, the rain and light sensor automatically switches on the parking lamps, low-beam headlamps and the license
plate lamp. This excludes weather-related
impairments to visibility, such as snow, fog or
spray.
If there is fog, snow or spray, turn the light
switch quickly from 0058to0058. You could
otherwise briefly interrupt operation of the
headlamps.
X To switch on automatic headlamp
mode: turn the light switch to 0058.
Key in position 1in the ignition lock: the
parking lamps switch on or off automati-
cally depending on the ambient light.

the "daytime running lamps" function using the on-board computer, the daytime run-
ning lamps are switched on. The parking
lamps and low-beam headlamps also
switch on or off automatically, depending
on the ambient light.
When the low-beam headlamps are
switched on, the 0058indicator lamp in the
instrument cluster lights up.
Fog lamps/rear fog lamp G
WARNING
If you suspect that driving conditions will be
foggy, turn the light switch to 0058before you
start your journey. Your vehicle may other-
wise not be visible and you could endanger
yourself and others. G
WARNING
In low ambient lighting or foggy conditions,
only switch from position 0058to0058 with
the vehicle at a standstill in a safe location.
Switching from 0058to0058 will briefly
switch off the headlamps. Doing so while driv-
ing in low ambient lighting conditions may
result in an accident.

Cornering lamps
The cornering lamps improve the illumination of the road over a wide angle in the direction
you are turning, enabling better visibility in
tight bends, for example.
The cornering light function switches on
automatically, if:
R you are traveling at a speed of less than
25 mph (40 km/h) and you switch on a turn signal or turn the steering wheel.
R you are traveling at a speed between
25 mph (40 km/ h)and 43 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 3 minutes.
i If reverse gear is engaged the lamp on the
opposite side of the vehicle switches on
instead. Hazard warning lamps
G
WARNING
The rear exterior light will be covered if you:
R open the rear doors by 90°
R open the rear dropside.
The vehicle will then be difficult for other road users to see or will not be seen by them at all,
particularly if it is dark or visibility is poor.
There is a risk of an accident.
You should therefore ensure in this and simi-
lar situations that the vehicle is visible from
the rear in accordance with the relevant
national regulations, by using the warning tri- angle, for instance. Hazard warning lamp switch
X
To switch on/off: press the002Fhazard
warning lamp switch.
If you have indicated a turn while the hazard
warning lamps are switched on, only the turn signal lamps on the side of the vehicle selec- ted will light up.
The hazard warning lamps switch on auto-
matically if:
R an air bag is deployed.
R you brake sharply and bring the vehicle to a
halt from a speed of more than 45 mph
(70 km/h).
If the hazard warning lamps have been
switched on automatically, press the 002F
hazard warning lamp switch to switch them
off.
i The hazard warning lamps work even
when the ignition is switched off. Headlamp cleaning system
The headlamps are cleaned automatically
with a high-pressure water jet if the "Wipe
with washer fluid" function is activated
(Y page 107) while the low-beam headlamps
are on and the engine is running.
You can find information on refilling washer
fluid in the "Maintenance and care" section
(Y page 255). Exterior lighting
