If you leave your lane, under certain circum-stances the vehicle will brake briefly on oneside. This is meant to assist you in bringing thevehicle back to the original lane.
If a lane-correcting brake application occurs,display Cappears in the multifunction dis-play.
A lane-correcting brake application can bemade after driving over a lane marking recog-nized as being solid or broken. Before this, awarning must have been issued by means of avibration through the steering wheel. In addi-tion, a lane with lane markings on both sidesmust have been detected.
In the case of a broken lane marking beingdetected, a lane-correcting brake applicationcan only be made if a vehicle has been detec-ted in the adjacent lane. The following vehiclescan have an influence on brake application:oncoming traffic, vehicles that are overtakingand vehicles that are driving parallel to yourvehicle.
iA further lane-correcting brake applicationcan only occur after your vehicle hasreturned to the original lane.
No lane-correcting brake application occurs if:
Ryou clearly and actively steer, brake oraccelerate
Ryou cut the corner on a sharp bend
Ryou have switched on the turn signal
Ra driving safety system intervenes, e.g.
ESP®, PRE-SAFE®Brake or Active Blind SpotAssist
Ryou have adopted a sporty driving style withhigh cornering speeds or high rates of accel-eration
RESP®is switched off
Rthe transmission is not in position [
Ran obstacle has been detected in the lane inwhich you are driving
Rwhen a loss of tire pressure or a defectivetire has been detected and displayed
There is a possibility that the Active LaneKeeping Assist could misjudge the given trafficsituation. An inappropriate brake applicationmay be interrupted at any time if you:
Rsteer slightly in the opposite direction
Rswitch on the turn signal
Rclearly brake or accelerate
A lane-correcting brake application is interrup-ted automatically if:
Ra driving safety system intervenes, e.g.
ESP®, PRE-SAFE®Brake or Active Blind SpotAssist
Rlane markings are no longer detected
Switching on Active Lane Keeping Assist
XSwitch on Active Lane Keeping Assist usingthe on-board computer; to do so, selectStandardStandardorAdaptiveAdaptive(Ypage 199).If you drive at speeds above 40 mph(60 km/h) and lane markings are detected,the lines in the assistance graphic displayare shown in green (Ypage 198). ActiveLane Keeping Assist is ready for use.
WhenStandardStandardis selected,
No warning vibration occurs if:
Ryou switch on the turn signals. In thisevent, the warnings are suppressed for acertain period of time.
Ra driving safety system intervenes, such
as ABS, BAS or ESP®.
WhenAdaptiveAdaptiveis selected,
No warning vibration occurs if:

Important safety notes
GWARNING
If you operate information systems and com-
munication equipment integrated in the
vehicle when driving, you may be distracted
from the traffic situation. You could also
lose control of the vehicle. There is a risk of
an accident.
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 equipment when the vehicle is station-
ary.
You must observe the legal requirements forthe country in which you are currently drivingwhen operating 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 messagesor warnings from certain systems in the multi-function display. You should therefore makesure your vehicle is operating safely at alltimes.
If the operating safety of your vehicle isimpaired, pull over as soon as it is safe to doso. Contact a qualified specialist workshop.
For an overview, see the instrument panelillustration (Ypage 33).
Displays and operation
Instrument cluster lighting
The lighting in the instrument cluster, in thedisplays and the controls in the vehicle interiorcan be adjusted using the brightness controlknob.
The brightness control knob is located on thebottom left of the instrument cluster(Ypage 33).
XTurn the brightness control knob clockwiseor counter-clockwise.If you turn the light switch (Ypage 109) tothe X, `or Xposition, the bright-ness will depend upon the brightness of theambient light.
The light sensor in the instrument clusterautomatically controls the brightness of themultifunction display. In daylight, the dis-plays in the instrument cluster are not illu-minated.
Speedometer with segments
The segments in the speedometer indicatewhich speed range is available.
RCruise control activated (Ypage 154):
The segments light up from the storedspeed to the maximum speed.
RActive Distance Assist DISTRONIC activated(Ypage 156):
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 thevehicle in front and the stored speed lightup.
Tachometer
!Do not drive in the overrevving range, asthis could damage the engine.
The red band in the tachometer indicates theengine's overrevving range.
The fuel supply is interrupted to protect theengine when the red band is reached.
