WARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is a risk of an accident.
Always steer, apply the brakes or accelerate
the vehicle yourself, especially if Lane Keep-
ing Assist alerts you.
If you fail to adapt your driving style, Lane Keep-
ing Assist can neither reduce the risk of an acci-
dent nor override the laws of physics. Lane
Keeping Assist cannot take into account road,
weather or traffic conditions. Lane Keeping
Assist is only 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
lane.
Lane Keeping Assist does not keep your vehicle
in its lane.
The system may be impaired or may not function if:
R there is poor visibility, e.g. due to insufficient
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 windscreen is dirty, misted up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
R no or several, unclear lane markings are pres-
ent for one lane, e.g. in a construction area
R the lane markings are worn away, dark or cov-
ered 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 detec-
ted
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 highly variable shade conditions on
the road
Activating Lane Keeping Assist
X Activate Lane Keeping Assist using the on-
board computer; to do so, select Standard
Standard or
Adaptive
Adaptive (Ypage 183).
If you drive at speeds above 60 km/h and lane
markings are detected, the lane markings in
the assistance graphics display (Y page 182)
are shown in green. When
Standard
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 cer-
tain period of time.
R a driving safety system intervenes, such as
ABS, BAS or ESP ®
.
When Adaptive 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 cer-
tain period of time.
R a driving safety system intervenes, such as
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 lane quickly.
R you cut the corner on a sharp bend.
In order that you are warned only when neces-
sary and in good time if you cross the lane mark-
ing, the system detects certain conditions 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 motorway
R the system detects solid lane markings
The warning vibration occurs later if:
R the road has narrow lanes
R you cut the corner on a bend Driving systems

tive braking effect by applying the brake your-
self. Charge level display

(Y page 177).

played n the COMAND/Audio display.
The charge level of the high-voltage battery has dropped into the reserve range if the drive sys-
tem is running and:
R the Drive battery Reserve level Drive battery Reserve level mes-
sage appears in the display
R the indicator lamp in the instrument cluster
lights up
Charge the high-voltage battery from a state of
charge of less than 20% at a:
R mains socket
R charging station
The braking performance of the electric motor
using recuperative braking is, in some operating
modes, either reduced or not effective:
R when the charge status of the high-voltage
battery increases
R if the high-voltage battery is not yet at a nor-
mal operating temperature
R when the vehicle is almost stationary
R in transmission position N
R during and after ESP stability control
If you do not make an additional effort to apply
the brake yourself, the braking effect may not be sufficient. If necessary, counteract the reduced regenerative braking effect by applying the
brake yourself. Operating the on-board computer
