180 Controls in detailClimate controlThe climate control is operational whenev-
er the engine is running. The system cools
or heats the interior depending on the se-
lected interior temperature and the cur-
rent outside temperature.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 179).
Warning!
G
When operating the climate control, the air
that enters the passenger compartment
through the air vents can be very hot or very
cold (depending on the set temperature).
This may cause burns or frostbite to unpro-
tected skin in the immediate area of the air
vents. Always keep sufficient distance be-
tween unprotected parts of the body and the
air vents. If necessary, use the air distribu-
tion controls (
page 179) to direct the air
to air vents in the vehicle interior that are
not in the immediate area of unprotected
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.

Setting the temperature
Use temperature controls1 and4
(page 179) 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

The climate control system will corre-
spondingly adjust the interior air tem-
perature.

Turn temperature control
1and/or4 (
page 179) slightly
counterclockwise.
The climate control system will corre-
spondingly adjust the interior air tem-
perature.
iWhen the climate control system is
switched off, the outside air supply and
circulation are also switched off. Only
choose this setting for a short time.
Otherwise the windows could fog up.

Turn air volume control2
(page 179) to level2 or higher.
Otherwise the windows may fog over.

effect.Windshield fogged on the outside

Switch the windshield wipers on
(page 56).

Turn air distribution control3 to
positionaorY (
page 179).
Air recirculation mode
Switch to air recirculation mode to prevent
unpleasant odors from entering the vehicle
from the outside (e.g. before driving
through a tunnel). This setting cuts off the
intake of outside air and recirculates the
air in the interior.
iThe cooling remains switched on.
Warning!
G
Fogged windows impair visibility, endanger-
ing you and others. If the windows begin to
fog on the inside, switching off the air
recirculation mode immediately should clear
interior window fogging. If interior window
fogging persists, make sure the air
conditioning (
page 187) is activated, or
press buttonP.

188 Controls in detailClimate controlMaximum cooling
Turn thumbwheels5and8
(page 178) upwards to the first stop.
The fixed center air vents4and9
(page 178) and the adjustable air
vents6and7 (
page 178) are
open.

For draft-free ventilation, move the
sliders for the center air vents
6and7 (
page 178) to the middle
position.

Turn thumbwheels1andc
(page 178) for the adjustable side air
vents2andb (
page 178) to the
fully open position.

Set air distribution control3
(page 182) to positiona.
The air distribution directs the air
through the center and side air vents.

Set air volume control2 (
page 183)
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.
