Important safety notes
GWARNING
Very hot or very cold air can flow from the
air vents. This could result in burns or frost-
bite in the immediate vicinity of the air
vents. There is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh airthrough the air vents into the vehicle interior,please observe the following notes:
Rkeep the air inlet between the windshieldand the hood free of blockages, such as ice,snow or leaves.
Rnever cover the air vents or air intake grillesin the vehicle interior.
iFor optimal climate control in the vehicle,open the air vents completely and set theadjusters to the central position.

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 32).
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 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 32).
XTurn the brightness control knob clockwiseor counter-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 seg-ments in vehicles with Active Distance AssistDISTRONIC.
The segments in the speedometer indicatewhich speed range is available.
RActive Distance Assist DISTRONIC activated(Ypage 158):
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 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 con-ditions when temperatures are around freezingpoint.
Bear in mind that the outside temperature dis-play indicates the temperature measured anddoes not record the road temperature.

For safety reasons, Mercedes-Benz recom-mends that you only use batteries which havebeen tested and approved for your vehicle byMercedes-Benz. These batteries provideincreased impact protection to prevent vehicleoccupants from suffering acid burns shouldthe battery be damaged in the event of anaccident.
In order for the battery to achieve the maxi-mum possible service life, it must always besufficiently charged.
Like other batteries, the vehicle battery maydischarge over time if you do not use the vehi-cle. In this case, have the battery disconnec-ted at a qualified specialist workshop. You canalso charge the battery with a charger recom-mended by Mercedes-Benz. Contact a quali-fied specialist workshop for further informa-tion.
Have the battery condition of charge checkedmore frequently if you use the vehicle mainlyfor short trips or if you leave it standing idlefor a lengthy period. Consult a qualified spe-cialist workshop if you wish to leave your vehi-cle parked for a long period of time.
Only replace a battery with a battery that hasbeen recommended by Mercedes-Benz.
Remove the SmartKey if you park the vehicleand do not require any electrical consumers.The vehicle will then use very little energy,thus conserving battery power.
If the power supply has been interrupted, e.g.if you reconnect the battery, you will have to:
Rset the clock using the multimedia system(see the Digital Operator's Manual)
Rreset the function for folding the exteriormirrors in/out automatically, by folding themirrors out once (Ypage 99)
Charging the battery
GWARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is
a risk of an explosion.
Particularly avoid fire, open flames, creating
sparks and smoking. Ensure there is suffi-
cient ventilation while charging and jump-
starting. Do not lean over a battery.
GWARNING
Battery acid is caustic. There is a risk of
injury.
Avoid contact with skin, eyes or clothing. Do
not inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash away battery acid immedi-
ately with plenty of clean water and seek
medical attention.
GWARNING
A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing the vehicle or charging the battery,
gases can escape from the battery. There is
a risk of an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
!Only use battery chargers with a maximumcharging voltage of 14.8 V.
!Only charge the battery using the jump-starting connection point.
The jump-starting connection point is in theengine compartment (Ypage 295).
XOpen the hood.
XConnect the battery charger to the positiveterminal and ground point in the same orderas when connecting the donor battery in thejump-starting procedure (Ypage 295).
If the indicator/warning lamps do not light upin the instrument cluster at low temperatures,it is very likely that the discharged battery hasfrozen. In this case you may neither jump-startthe vehicle nor charge the battery. The servicelife of a thawed-out battery may be shorter.The starting characteristics can be impaired,
