Lane Keeping Assist
General notes
Lane Keeping Assist monitors the area in
front of your vehicle by means of multifunc-
tion camera C which is attached behind the
top of the windshield. Active Lane Keeping
Assist detects lane markings on the road and
can warn you before you leave your lane unin-
tentionally.
This function is available in the range between
40 mph and 120 mph (60 km/h and
200 km/h).
A warning may be given if a front wheel
passes over a lane marking. It will warn you by
means of intermittent vibration in the steer-
ing wheel for up to 1.5 seconds. Important safety notes
G WARNING
Lane Keeping Assist may not always clearly
recognize lane markings.
In this case, Lane Keeping Assist may: R
give an unnecessary warning R
not give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and stay in lane, in particular if
warned by Lane Keeping Assist.
G WARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is
a risk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane Keep-
ing Assist.
If you fail to adapt your driving style, Lane
Keeping Assist can neither reduce the risk of
an accident nor override the laws of physics.
Lane Keeping Assist cannot take into account
the road, traffic and weather conditions. Lane
Keeping Assist is merely an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in your lane.
The Lane Keeping Assist does not keep the
vehicle in the lane.
The system may be impaired or may not func-
tion if: R
there is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray R
there is glare, e.g. from oncoming traffic,
the sun or reflection from other vehicles
(e.g. if the road surface is wet) R
the windshield is dirty, fogged up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera R
there are no, several or unclear lane mark-
ings for a lane, e.g. in areas with road con-
struction work Driving systems 207
Driving and parking Z

R
the lane markings are worn away, dark or
covered up, e.g. by dirt or snow R
the distance to the vehicle in front is too
small and the lane markings thus cannot be
detected R
the lane markings change quickly, e.g.
lanes branch off, cross one another or
merge R
the road is narrow and winding R
there are strong shadows cast on the road
Switching on Lane Keeping Assist X
Activate Lane Keeping Assist using the on-
board computer; to do so, select Standard
or Adaptive ( Y
page 220).
If you drive at speeds above 40 mph
(60 km/h) and lane markings are detected,
the lines in the assistance graphics display
( Y
page 219) are shown in green. Lane
Keeping Assist is ready for use.
When Standard
is selected, no warning vibra-
tion occurs if: R
you have switched on the turn signal. In this
event, the warnings are suppressed for a
certain period of time. R
a driving safety system intervenes, such as
ABS, BAS or ESP ®
.
When Adaptive is selected, no warning vibra-
tion occurs if: R
you have switched on the turn signal. In this
event, the warnings are suppressed for a
certain period of time. R
a driving safety system intervenes, e.g.
ABS, BAS or ESP ®
.R
you accelerate hard, e.g. kickdown. R
you brake hard. R
you steer actively, e.g. swerve to avoid an
obstacle or change lanes quickly. R
you cut the corner on a sharp bend.
In order that you are warned only when nec-
essary and in good time if you cross the lane
marking, the system recognizes certain con-
ditions and warns you accordingly. The warning vibration occurs earlier if: R
you approach the outer lane marking on a
bend. R
the road has very wide lanes, e.g. a free-
way. R
the system recognizes solid lane markings.
The warning vibration occurs later if: R
the road has narrow lanes. R
you cut the corner on a bend.208

purposes.
Notes on 4MATIC vehicles
! Vehicles with 4MATIC must not be towed
with either the front or the rear axle raised,
as doing so will damage the transmission.
Vehicles with 4MATIC may only either be
towed away with both axles on the ground or
be loaded up and transported.
If the vehicle's transmission, front, or rear
axle is damaged, have the vehicle transported
on a truck or trailer.
In the event of damage to the electrical
system:
If the battery is defective, the automatic
transmission will be locked in position P . To
shift the automatic transmission to position
N , you must provide power to the vehicle's
electrical system in the same way as when
jump-starting ( Y
page 319).
Have the vehicle transported on a transporter
or trailer.324
