Automatic climate control
The automatic climate control is operation-
al whenever the engine is running. You can
operate the climate control system in ei-
ther the automatic or manual mode. The
system cools or heats the interior depend-
ing on the selected interior temperature
and the current outside temperature.Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the passenger compartment through
the air distribution system.
Adjusting the temperature
Use temperature controls6 andb to
separately adjust the air temperature on
each side of the passenger compartment.
You should raise or lower the temperature
setting in small increments, preferably
starting at 72°F (22°C).
Increasing
Turn the outer adjustment ring slightly
to the right.
The automatic climate control system
will correspondingly adjust the interior
air temperature.
Warning!
G
When operating the automatic climate con-
trol, the air that enters the passenger com-
partment through the air vents can be very
hot or very cold (depending on the set tem-
perature). This may cause burns or frostbite
to unprotected skin in the immediate area of
the air vents. Always keep sufficient dis-
tance between unprotected parts of the
body and the air vents. If necessary, use the
air distribution controls (
page 187) to di-
rect the air to air vents in the vehicle interior
that are not in the immediate area of unpro-
tected skin.
Warning!
G
Follow the recommended settings for heat-
ing and cooling given on the following pag-
es. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.iIf the vehicle interior is hot, ventilate
the interior before driving off.
Keep the air intake grille in front of the
windshield free of snow and debris.
iWhen operating the climate control
system in automatic mode, you will
only rarely need to adjust the tempera-
ture, air volume and air distribution.

348 Practical hintsReplacing bulbsSafe vehicle operation depends on proper
exterior lighting and signaling. It is there-
fore essential that all bulbs and lamp as-
semblies are in good working order at all
times.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. See an authorized
Mercedes-Benz Center for headlamp ad-
justment.
!You must not change the bulbs or LEDs
yourself, as you could damage the vehi-
cle lighting systems.
Have blown bulbs or LEDs replaced by
an authorized Mercedes-Benz Center.iIf the headlamps are fogged up on the
inside as a result of high humidity, driv-
ing the vehicle a distance should clear
up the fogging.
iSubstitute bulbs will be brought into
use when lamps malfunction. Observe
the messages in the multifunction dis-
play (
page 330).
iIf one of the following bulbs blows, an-
other bulb will adopt its function:
Rear turn signals
Brake lamps
Side lamps
Tail lamps
