186 Controls in detailAutomatic climate controlThe automatic climate control is operation-
al whenever the engine is running. You can
operate the automatic climate control sys-
tem in either the automatic or manual
mode. The system cools or heats the inte-
rior depending on the selected interior
temperature and the current outside tem-
perature.Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the passenger compartment through
the air distribution system.
The air conditioning will not engage (no
cooling) if the A/Cmode is deactivated
(
page 193).
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
on 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 control (
page 185) 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.
i
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before its
scheduled interval. A clogged filter will reduce
the air volume to the interior.
If the vehicle interior is hot, ventilate the interior
before driving off. The automatic climate control
will then adjust the interior temperature to the
set value much faster.
Keep the air intake grille in front of the wind-
shield free of snow and debris.
When the retractable hardtop is closed, do not
obstruct air flow by placing objects on the air
flow-through exhaust slots below the rear win-
dow.
