Activating/deactivating the rear view
camera
XTo activate:make sure that the SmartKey isin positionHin the ignition lock.
XMake sure that theActivation by R gearActivation by R gearfunction is selected in the multimedia system;see the Digital Operator's Manual.
XEngage reverse gear.The area behind the vehicle is shown withguide lines in the multimedia system display.
The image from the rear view camera is avail-able throughout the maneuvering process.
To deactivate:the rear view camera deacti-vates if you shift the transmission to]or afterdriving forwards a short distance.
The inner segments of the warning indicator aredisplayed in red if there is a complete systemfailure. The indicator lamp in the PARKTRONICbutton lights up.
If the system fails at the rear of the vehicle:
Rthe rear segments are shown in red whenbacking up.
Rthe rear segments are hidden when drivingforwards.
Messages in the multimedia system dis-
play
The rear view camera may show a distorted viewof obstacles, show them incorrectly or not at all.The rear view camera does not show objects inthe following positions:
Rvery close to the rear bumper
Runder the rear bumper
Rin close range above the handle on the trunklid
!Objects not at ground level may appear tobe further away than they actually are, e.g.:
Rthe bumper of a parked vehicle
Rthe drawbar of a trailer
Rthe ball coupling of a trailer tow hitch
Rthe rear section of an HGV
Ra slanted post
Use the guidelines only for orientation.Approach objects no further than the bottom-most guideline.
CYellow guide line at a distance of approx-imately 13 ft (4.0 m) from the rear of thevehicle
DWhite guide line without steering input –vehicle width including the exterior mirrors(static)

Any unauthorized modification to this devicecould void the user’s authority to operate theequipment.
Radar sensors
The radar sensors for Blind Spot Assist are inte-grated into the rear bumper. Make sure that thebumpers are free from dirt, ice or slush. Thesensors must not be covered, for example bycycle racks or overhanging loads. Following asevere impact or in the event of damage to thebumpers, have the function of the radar sensorschecked at a qualified specialist workshop.Blind Spot Assist may no longer work properly.
Monitoring range of the sensors
In particular, the detection of obstacles can beimpaired if:
Rthere is dirt on the sensors or anything elsecovering the sensors
Rthere is poor visibility, e.g. due to fog, heavyrain or snow
Ra narrow vehicle traveling in front, e.g. amotorbike or bicycle
Rthe road has very wide lanes
Rthe road has narrow lanes
Ryou are not driving in the middle of the lane
Rthere are barriers or other road boundaries
Vehicles in the monitoring range are then notindicated.
Blind Spot Assist monitors the area up to 10 ft(3 m) behind your vehicle and directly next to it.
If the lanes are narrow, vehicles driving in thelane beyond the lane next to your vehicle may beindicated, especially if the vehicles are not driv-ing in the middle of their lane. This may be thecase if the vehicles are driving on the inner sideof their lane.
Due to the nature of the system:
Rwarnings may be issued in error when drivingclose to crash barriers or similar solid laneborders.
Rwarnings may be interrupted when you aredriving alongside particularly long vehicles,such as trucks, for a prolonged time.
Warning display
CWarning display
Blind Spot Assist is not active at speeds belowapproximately 20 mph (30 km/h). Vehicles inthe monitoring range are then not indicated.
When Blind Spot Assist is activated, indicatorlampCin the exterior mirrors lights up yellowat speeds of up to 20 mph (30 km/h). At speedsabove 20 mph (30 km/h), the indicator lampgoes out and Blind Spot Assist is operational.
If a vehicle is detected within the blind spotmonitoring range at speeds above 20 mph(30 km/h), warning lampCon the correspond-ing side lights up red. This warning is alwaysemitted when a vehicle enters the blind spotmonitoring range from behind or from the side.When you overtake a vehicle, the warning onlyoccurs if the difference in speed is less than7 mph (12 km/h).
The yellow indicator lamp goes out if reversegear is engaged. In this event, Blind Spot Assistis no longer active.
The brightness of the indicator/warning lampsis adjusted automatically according to the ambi-ent light.
Collision warning
If a vehicle is detected in the monitoring range ofBlind Spot Assist and you switch on the corre-sponding turn signal, a double warning tonesounds. Red warning lampCflashes. If the turnsignal remains on, vehicles detected are indica-ted by the flashing of red warning lampC.There are no further warning tones.

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).
178Displays and operation
On-board computer and displays

There is a short delay before a change in outsidetemperature appears in the multifunction dis-play.
Coolant temperature gauge
GWARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
!A display message is shown if the coolanttemperature is too high.
If the coolant temperature is over 248 ‡(120 †), do not continue driving. The enginewill otherwise be damaged.
The coolant temperature gage is in the instru-ment cluster on the right-hand side (Ypage 33).
TheHmarking in the coolant temperature gaugecorresponds to a coolant temperature ofapproximately 248 ‡ (120 †).
Under normal operating conditions and at thecorrect coolant level, the coolant temperaturegauge may rise to theHmarking.
