Rthere are vehicles or obstacles, e.g. crashbarriers, located on both sides of your vehi-cle.
Ra vehicle approaches you too closely at theside.
Ryou have adopted a sporty driving style withhigh cornering speeds.
Ryou clearly brake or accelerate.
Ra driving safety system intervenes, e.g.
ESP®or PRE-SAFE®Brake.
RESP®is switched off.
Ra loss of tire pressure or a defective tire isdetected.

Active Lane Keeping Assist
General notes
Active Lane Keeping Assist monitors the areain front of your vehicle by means of multifunc-tion camera Cat the top of the windshield.Various areas to the front, rear and side ofyour vehicle are also monitored with the aid ofthe radar sensor system. Active Lane KeepingAssist detects lane markings on the road andcan warn you before you leave your lane unin-tentionally. If you do not react to the warning,a lane-correcting application of the brakes canbring the vehicle back into the original lane.
This function is available in a speed rangebetween 40 mph and 120 mph (60 km/h and200 km/h).
For Active Lane Keeping Assist to assist youwhen driving, the radar sensor system must beoperational.
Important safety notes
If you fail to adapt your driving style, ActiveLane Keeping Assist can neither reduce therisk of accident nor override the laws of phys-ics. Active Lane Keeping Assist cannot takeinto account road, weather or traffic condi-tions. Active Lane Keeping Assist is only anaid. You are responsible for the distance to thevehicle in front, for vehicle speed, for brakingin good time and for staying in your lane.
Active Lane Keeping Assist cannot continu-ously keep your vehicle in its lane.
GWARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.

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.
Outside temperature display
You should pay special attention to road con-ditions when temperatures are around freezingpoint.

Cleaning the sensors
!If you clean the sensors with a powerwasher, make sure that you keep a distanceof at least 11.8 in(30 cm) between the vehi-cleand the power washer nozzle. Informa-tion about the correct distance is availablefrom the equipment manufacturer.
XClean sensors Cof the driving systemswith water, car shampoo and a soft cloth.
Cleaning the reversing camera
!Do not clean the camera lens and the areaaround the rear view camera with a powerwasher.

Cleaning the exhaust pipe
GWARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could
burn yourself. There is a risk of burns.
Always be particularly careful and supervise
children closely around the exhaust pipe and
the exhaust pipe trims. Allow these compo-
nents to cool down before touching them.
!Do not clean the exhaust pipe with acid-based cleaning agents, such as bathroomcleaner or wheel cleaner.
XClean the exhaust pipe with a chrome careproduct tested and approved by Mercedes-Benz.
Impurities combined with the effects of roadgrit and corrosive environmental factors maycause flash rust to form on the surface. Youcan restore the original shine of the exhaustpipe by cleaning it regularly, especially in win-ter and after washing.
