Important safety notes
G WARNING
Very hot or very cold air can flow from the air
vents. This could result in burns or frostbite 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 air
through the air vents into the vehicle interior,
please observe the following notes: R
keep the air inlet between the windshield
and the hood free of blockages, such as ice,
snow or leaves. R
never cover the air vents or air intake grilles

Important safety notes
G WARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle while driving, you will be distracted from
traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate the 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
the country in which you are currently driving
when operating the on-board computer.
G WARNING
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
or warnings from certain systems in the mul-
tifunction display. You should therefore make sure your vehicle is operating safely at all
times.
If the operating safety of your vehicle is
impaired, pull over as soon as it is safe to do
so. Contact a qualified specialist workshop.
For an overview, see the instrument panel
illustration ( Y
page 31).
Displays and operation
Instrument cluster lighting The light sensor in the instrument cluster
automatically controls the brightness of the
multifunction display. In daylight, the displays
in the instrument cluster are not illuminated.
The lighting in the instrument cluster, in the
displays and the controls in the vehicle inte-
rior can be adjusted using the brightness con-
trol knob.
The brightness control knob is located on the
bottom left of the instrument cluster
( Y
page 31). X
Turn the brightness control knob clockwise
or counter-clockwise.
If the light switch is set to the X , ` or
X position, the brightness is dependent
upon the brightness of the ambient light.
Speedometer with segments
The speedometer is divided into segments
only on vehicles with DISTRONIC PLUS.
The segments in the speedometer indicate
which speed range is available. R
DISTRONIC PLUS activated ( Y
page 186):
One or two segments in the set speed
range light up. R
DISTRONIC PLUS detects a vehicle in front
that is driving at a slower speed than the
stored speed:

For safety reasons, Mercedes-Benz recom-
men ds that you only use batteries which have
been tested and approved for your vehicle by
Mercedes-Benz. These batteries pro vide
increased impact protection to prevent veh i-
cle occupants from suffering acid burns
should the battery be damaged in the event of
an acc iden t.
In order for the battery to achieve the max i-
mum poss ible service life, it must always be
suff icie nt ly charge d.
Like other batteries, the vehicle battery may
disc harge over time if you do not use the
veh icle . In th is case, have the battery discon-
nected at a qualif ied specialist workshop. You
can also charge the battery with a charger
recommended by Mercedes-Benz. Contact a qualif ied spec ialist workshop for further infor-
mation.
Have the battery condition of charge checked
more frequently if you use the vehicle main ly
for short trips or if you leave it standing idle
for a lengthy per iod. Consult a qualif ied spe-
cialist workshop if you wish to leave your
vehicle parked for a long period of time.
On ly replace a battery with a battery that has
been recommended by Mercedes-Benz.
Remo ve the Sm artKey if you park the vehicle
and do not require any electrical consumers.
The vehicle will then use very lit tle energy,
t hus conserving battery power.
If the power supply has been interrupted, e.g.
if you reconnect the battery, you will have to:R
set the clock via Aud io 20 or COMAND (see
separate operating instructions). R
reset the function for folding the exterior
mirrors in/out automatically, by folding the
mirrors out once ( Y
