(page 182) to positiona.
The air distribution directs the air
through the center and side air vents.

to position5.
The ventilation operates with maximum
blower speed.

Turn temperature controls1and4
(page 179) completely counterclock-
wise to their end stops.
The lowest temperature for both sides
is set.
Residual engine heat utilization
With the engine switched off, it is possible
to continue to heat or ventilate the interior
for up to 30 minutes. This feature makes
use of the residual heat produced by the
engine.
iWhen the vehicle’s interior has cooled
down enough, reduce the air volume
and increase the air temperature to
comfortable settings if desired.

193 Controls in detail
Automatic climate control*
The 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 interior through the air distribution
system.
The air conditioning will not engage (no
cooling) if the A/Cmode is deactivated
(
page 192).
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 controls (
page 192) 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.
iSevere conditions (e.g. strong air pollu-
tion) may require replacement of the fil-
ter before its scheduled interval.
A clogged filter will reduce the air vol-
ume to the interior.
If the vehicle interior is hot, ventilate
the interior before driving off. The cli-
mate control will then adjust the interi-
or temperature to the set value much
faster.
Keep the air intake grille in front of the
windshield free of snow and debris.
When the retractable hardtop is closed,
do not obstruct air flow by placing ob-
jects on the air flow-through exhaust
slots below the rear window.

midify is switched on. This function can

Use temperature controls4andc for
the left side or6andb for the right side
(page 192) to separately adjust the air
temperature on each side of the passenger
compartment. You should raise or lower
the temperature setting in small incre-
ments, preferably starting at 72°F (22°C).
The climate control will adjust to the set
temperature as fast as possible.Increasing
