Lane Keeping Assist
General notes
Lane Keeping Assist monitors the area in front ofyour vehicle by means of multifunction cam-eraCwhich is attached behind the top of thewindshield. Lane Keeping Assist detects lanemarkings on the road and can warn you beforeyou leave your lane unintentionally.
This function is available in the range between40 mph and 120 mph (60 km/h and 200 km/h).
A warning may be given if a front wheel passesover a lane marking. It will warn you by means ofintermittent vibration in the steering wheel forup to 1.5 seconds.
Important safety notes
GWARNING
Lane Keeping Assist cannot always clearly
detect lane markings.
In such cases, Lane Keeping Assist can:
Rgive an unnecessary warning
Rnot give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Lane Keeping Assist alerts you.
GWARNING
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 Keep-ing Assist can neither reduce the risk of an acci-dent nor override the laws of physics. LaneKeeping Assist cannot take into account theroad, traffic and weather conditions. Lane Keep-ing Assist is merely an aid. You are responsiblefor the distance to the vehicle in front, for vehi-cle speed, for braking in good time and for stay-ing in your lane.
The Lane Keeping Assist does not keep the vehi-cle in the lane.
The system may be impaired or may not functionif:
Rthere is poor visibility, e.g. due to insufficientillumination of the road, or due to snow, rain,fog or spray
Rthere is glare, e.g. from oncoming traffic, thesun or reflection from other vehicles (e.g. ifthe road surface is wet)
Rthe windshield is dirty, fogged up, damaged orcovered, for instance by a sticker, in the vicin-ity of the camera
Rthere are no or several unclear lane markingsfor one lane, e.g. roadworks
Rthe lane markings are worn away, dark or cov-ered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is too shortand thus the lane markings cannot be detec-ted
Rthe lane markings change quickly, e.g. lanesbranch off, cross one another or merge
Rthe road is narrow and winding
Rthere are highly variable shade conditions onthe roadway
Switching on Lane Keeping Assist
XSwitch on Active Lane Keeping Assist usingthe on-board computer; to do so, selectStandardStandardorAdaptiveAdaptive(Ypage 176).If you drive at speeds above 40 mph(60 km/h) and lane markings are detected,the lines in the assistance graphic are shown

Important safety notes
GWARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle when driving, you may be distracted from
the traffic situation. You could also lose con-
trol of the vehicle. There is a risk of an acci-
dent.
Only operate this equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
You must observe the legal requirements for thecountry in which you are currently driving whenoperating the on-board computer.
GWARNING
If the instrument cluster has failed or mal-
functioned, you may not recognize function
restrictions in systems relevant to safety. The
operating safety of your vehicle may be
impaired. There is a risk of an accident.
Drive on carefully. Have the vehicle checked
at a qualified specialist workshop immedi-
ately.
The on-board computer only shows messages orwarnings from certain systems in the multifunc-tion display. You should therefore make sureyour vehicle is operating safely at all times.
If the operating safety of your vehicle isimpaired, pull over as soon as it is safe to do so.Contact a qualified specialist workshop.
For an overview, see the instrument panel illus-tration (Ypage 33).
Displays and operation
Instrument cluster lighting
The light sensor in the instrument cluster auto-matically controls the brightness of the multi-function display. In daylight, the displays in theinstrument cluster are not illuminated.
The lighting in the instrument cluster, in the dis-plays and the controls in the vehicle interior canbe adjusted using the brightness control knob.
The brightness control knob is located on thebottom left of the instrument cluster(Ypage 33).
XTurn the brightness control knob clockwise orcounter-clockwise.If the light switch is set to theX,`orXposition, the brightness is dependentupon the brightness of the ambient light.
Speedometer with segments
The speedometer is only divided into segmentsin vehicles with Active Distance AssistDISTRONIC.
The segments in the speedometer indicatewhich speed range is available.
RActive Distance Assist DISTRONIC activated(Ypage 152):
One or two segments in the set speed rangelight up.
RActive Distance Assist DISTRONIC detects avehicle in front moving more slowly than thestored speed:
The segments between the speed of the vehi-cle in front and the stored speed light up.
Tachometer
!Do not drive in the overrevving range, as thiscould damage the engine.
The red band in the tachometer indicates theengine's overrevving range.
The engine is limited within a range to protectthe engine when the red band is reached.
Outside temperature display
You should pay special attention to road condi-tions when temperatures are around freezingpoint.
Bear in mind that the outside temperature dis-play indicates the temperature measured anddoes not record the road temperature.
The outside temperature display is in the multi-function display (Ypage 181).

%QThe yellow ABS warning lamp is lit while the engine is running.
ABS (Anti-lock Braking System) is deactivated due to a malfunction. Therefore,
BAS (Brake Assist), Active Brake Assist, ESP®(Electronic Stability Program), theHOLD function and hill start assist, for example, are also deactivated.
ATTENTION ASSIST is deactivated.
GWARNING
The brake system continues to function normally, but without the functions listedabove. The wheels could therefore lock if you brake hard, for example.
The steerability and braking characteristics may be severely affected. The brakingdistance in an emergency braking situation can increase.
If ESP®is not operational, ESP®is unable to stabilize the vehicle.
There is an increased risk of skidding and an accident.
XObserve the additional display messages in the multifunction display.

%QThe yellow ABS warning lamp is lit while the engine is running.
ABS is temporarily unavailable. Therefore, BAS, Active Brake Assist, ESP®, EBD(electronic brake force distribution), the HOLD function and hill start assist, forexample, are also deactivated.
Possible causes are:
Rself-diagnosis is not yet complete
Rthe on-board voltage may be insufficient
ATTENTION ASSIST is deactivated.
