172 Controls in detailAutomatic climate controlThe 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.
Setting the temperature
Use temperature controls1 and7 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 in the
footwell can be very hot or very cold (de-
pending on the set temperature). This may
cause burns or frostbite on unprotected skin
in the immediate area of the air vents. Al-
ways keep sufficient distance between un-
protected parts of the body and the footwell
air vents. If necessary change the air flow
using the air distribution controls to direct
the air away from the footwell air vents
(page 174).
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.
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.
iWhen operating the climate control
system in automatic mode, you will
only rarely need to adjust the tempera-
ture, air volume and air distribution.
174 Controls in detailAutomatic climate controlAdjusting air distribution
Use air distribution controls2 and6
(page 171) to separately adjust the air
distribution on each side of the passenger
compartment. The following symbols are
found on the controls:
Adjusting manually
Press the control knob.
The U light on the control knob
goes out. The air distribution can be ad-
justed manually.Adjusting automatically

The U light on the control knob
comes on. The air distribution is adjust-
ed automatically.
Windshield fogged on the outside
Switch the windshield wipers on.
Turn the air distribution control to h
or j.
Maximum cooling MAXCOOL
If the left and right air distribution controls
as well as the airflow volume control are
set to U and there is a high need for
cooling, MAXCOOL is activated.
This provides the fastest possible cooling
of the vehicle interior (when retractable
hardtop is closed).
