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 dipped-beam headlamps are switched on.
Active:
R if you are driving at speeds below
40 km/h and the turn signal is activated or
the steering wheel is turned.
R if you are driving at speeds between
40 km/h and 70 km/h and turn the steer-
ing wheel.
Not active: if you are driving at speeds above
40 km/h or switch off the turn signal or turn
the steering wheel to the straight-ahead posi-
tion.
The cornering lamp may remain lit for a short
time, but is automatically switched off after
no more than three minutes.
Motorway mode Motorway mode increases the range of the
beam.
Active:
R
if you are driving at speeds above
110 km/h and do not make any large steer-
ing movements for 1,000 m.
R if you are driving at speeds above
130 km/h.
Not active: if you are driving at speeds below
80 km/h following activation.
Extended range foglamps The extended range foglamps reduce the
glare experienced by the driver and improve
the illumination of the edge of the carriage-
way.
Active:
if you are driving at speeds below
70 km/h and you switch on the rear foglamp.
Not active: if, following activation, you are
driving at speeds above 100 km/h or if you
switch off the rear foglamp.
Off-road lights The off-road lights facilitate the early recog-
nition of objects/obstacles when driving off-
road thanks to a symmetrical, wider and
brighter distribution of light from the dipped-
beam headlamps.
Active: when driving at speeds below
50 km/h and the Off-road program is
switched on (Y page 215).
Not active: when driving at speeds above
50 km/h. Exterior lighting

Keep bulbs out of the reach of children. Oth-
erwise, they could damage the bulbs, for
example, and injure themselves.
Never use a bulb which has been dropped.
Such a bulb may break or even explode and
injure you.
Halogen bulbs are pressurised and can
explode when you change them, particularly
if they are very hot. You should therefore wear
eye protection and gloves when you are
changing them.
There are bulbs other than the xenon bulbs
that you cannot replace. Replace only the
bulbs listed (Y page 119). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop.
If you require assistance changing bulbs, con-
sult a qualified specialist workshop.
Do not touch the glass tube of new bulbs with
your bare hands. Even minor contamination
can burn into the glass surface and reduce
the service life of the bulbs. Always use a lint-
free cloth or only touch the base of the bulb
when fitting.
Only use bulbs of the correct type.
If the new bulb still does not light up, consult
a qualified specialist workshop.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly. Overview of bulb replacement – bulbs
You can replace the following bulbs. The
details for the bulb type can be found in the
legend. Halogen headlamps

WARNING
The windscreen will not longer be wiped prop-
erly if the wiper blades are worn. This could
prevent you from observing the traffic condi-
tions, thereby causing an accident. Replace
the wiper blades twice a year, ideally in spring
and autumn.
! Do not operate the windscreen wipers
when the windscreen is dry, as this could damage the wiper blades. Moreover, dust
that has collected on the windscreen can
scratch the glass if wiping takes place when
the windscreen is dry.
! If the windscreen wipers leave smears on
the windscreen after the vehicle has been
washed in an automatic car wash, this may
be due to wax or other residue. Clean the
windscreen with washer fluid after an auto-
matic car wash. Combination switch

WARNING
If you depress the brake, DISTRONIC PLUS is
deactivated unless your vehicle is stationary.
DISTRONIC PLUS then no longer brakes your
vehicle. In such cases, control the distance
from vehicles travelling in front with the brake
alone. You could otherwise cause an accident
and thereby injure yourself and others. The
driver remains fully responsible for the vehi-
cle's distance from other vehicles, the speed
being driven and for braking in good time.
Changing lanes
If you change to the overtaking lane, DIS-
TRONIC PLUS supports you if:
R you are driving faster than 60 km/h.
R DISTRONIC PLUS is maintaining the dis-
tance to a vehicle in front.
R you switch on the respective turn signals.
R DISTRONIC PLUS does not detect a danger
of collision.
If these conditions are met, your vehicle is
accelerated. Acceleration will be interrupted
if changing lanes takes too long or if the dis-
tance between your vehicle and the vehicle in
front becomes too small.
i When changing lanes, DISTRONIC PLUS
monitors the left lane for left-hand-drive
vehicles and the right lane for right-hand-
drive vehicles. G
WARNING
DISTRONIC PLUS and Active Blind Spot Assist
are only an aid designed to assist driving.
They do not relieve you of the responsibility
of paying attention. The driver remains fully
responsible for the vehicle's distance from
other vehicles, the vehicle's speed and for
braking in good time. Always pay attention to
traffic conditions and your surroundings. Oth-
erwise, you may fail to recognise dangers in
time, cause an accident and injure yourself
and others. Vehicles with COMAND Online
i
The following function is not operational
in all countries.
DISTRONIC PLUS uses additional information
from your navigation system so that it can
adapt to certain traffic situations. This is the
case if, while following a vehicle, DISTRONIC
PLUS is active and you:
R approach or drive around a roundabout
R approach a T-junction
R turn off at a motorway exit
Even if the vehicle in front leaves the detec-
tion range, DISTRONIC PLUS temporarily
maintains the current driving speed and does
not accelerate. This is based on the current
map data in the navigation system. Example: roundabout
The current speed is maintained:
R
approximately 10 seconds before the
roundabout/T-junction and for approx-
imately 1.5 seconds when driving on the
roundabout
R approximately 12 seconds before reaching
a motorway exit and approximately 4 sec-
onds after the motorway exit
Afterwards, the vehicle accelerates back to
the set speed you specified.

Blind Spot Assist Important safety notes
Blind Spot Assist uses a radar sensor system
to monitor the areas on both sides of your
vehicle. It supports you from speeds of
30 km/h. A warning display in the exterior
mirrors draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
change lane, you will also receive an optical
and audible collision warning. For monitoring,
Active Blind Spot Assist uses sensors in the
rear bumper.

WARNING
Blind Spot Assist is only an aid designed to
assist driving. It may fail to detect some vehi-
cles and is no substitute for attentive driving.
Blind Spot Assist cannot detect road and traf-
fic conditions. It may fail to detect narrow Driving systems
