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-

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.
Only for Canada:
The daytime running lamps improve the visi-
bility of your vehicle during the day. The day- time running lamps function is required by lawin 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 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.
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
(Y page 277).
If the engine is running and you turn the light
switch to 0060or0058, the manual settings
take precedence over the daytime running
lamps.
i In the USA, the daytime running lamps are
deactivated upon delivery from the factory.

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.

Tips for driving with DISTRONIC PLUS General notes
Pay particular attention in the following traffic
situations:
R cornering, going into and coming out of a
bend
R vehicles traveling on a different line
R other vehicles changing lanes
R narrow vehicles
R obstructions and stationary vehicles
R crossing vehicles
In such situations, brake if necessary. DIS-
TRONIC PLUS is then deactivated.
Cornering, going into and coming out of a bend The ability of DISTRONIC PLUS to detect vehi-
cles when cornering is limited. Your vehicle
may brake unexpectedly or late. Driving syste

Activating ATTENTION ASSIST
X
Activate ATTENTION ASSIST using the on-
board computer (Y page 276).
When ATTENTION ASSIST is deactivated, the 00D7 symbol appears in the multifunction
display in the assistance graphic display.
ATTENTION ASSIST is activated automatically
after the engine is started up.
Warning and display messages in the
multifunction display If fatigue or increasing lapses in concentra-
tion are detected, a warning appears in the
multifunction display: Attention Assist: Attention Assist:
Take a Break!
Take a Break!
In addition to the message shown in the mul-
tifunction display, you will then hear a warn-
ing tone.
X If necessary, take a break.
X Confirm the message by pressing the 0076
button on the steering wheel.
On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you
do not take a break, you will be warned again
after 15 minutes at the earliest. The precon-
dition for this is that ATTENTION ASSIST still
detects typical indicators of fatigue or
increasing lapses in concentration. Night View Assist Plus
General notes In addition to the illumination provided by the
normal headlamps, Night View Assist Plus
uses infrared light to illuminate the road.
Night View Assist Plus camera 0043picks up the
infrared light and displays a monochrome
image in COMAND. The image displayed in
COMAND corresponds to a road lit up by high- beam headlamps. This enables you to see the
road's course and any obstacles in good time. If pedestrian recognition is activated, pedes-
trians recognized by the system are highligh-
ted in the Night View Assist Plus display.
Light from the headlamps of oncoming vehi-
cles does not affect the Night View Assist Plus
display in the multifunction display. This is
also the case if you cannot switch on the high-
beam headlamps due to oncoming traffic.
i Infrared light is not visible to the human
eye and therefore does not glare. Night
View Assist Plus can therefore remain
switched on even if there is oncoming traf- fic.
Important safety notes Night View Assist Plus is only an aid and is not
a substitute for attentive driving. Do not rely
on the Night View Assist Plus display. You are responsible for the distance to the vehicle in
front, for vehicle speed and for braking in
good time. Drive carefully and always adapt
your driving style to suit the prevailing road
and traffic conditions.
The system may be impaired or may not func-
tion if:
R there is poor visibility, e.g. due to snow,
rain, fog or spray
R the windshield is dirty, fogged up or cov-
ered, for instance by a sticker, in the vicinity
of the camera
R on bends, on uphill gradients or downhill

If a lane-correcting brake application occurs,
display 0043appears in the multifunction dis-
play.
If you leave your lane, under certain circum-
stances the vehicle will brake briefly on one
side. This is meant to assist you in bringing
the vehicle back to the original lane.
This function is available in the range between
40 mph and 120 mph (60 km/h and
200 km/h).
A lane-correcting brake application can only
be made after driving over a solid, recogniz-
able lane marking. Before this, a warning
must be given by means of intermittent vibra-
tion in the steering wheel. In addition, a lane
with lane markings on both sides must be
recognized. The brake application also
slightly reduces vehicle speed.
i A further lane-correcting brake applica-
tion can only occur after your vehicle has
returned to the original lane.
No lane-correcting brake application occurs
if:
R you clearly and actively steer, brake or
accelerate.
R you cut the corner on a sharp bend.
