183 Controls in detail
Good visibility
Rear window defroster
The rear window defroster uses a large
amount of power. To keep the battery
drain to a minimum, switch off the defrost-
er as soon as the rear window is clear. The
defroster is automatically deactivated af-
ter approximately 6 to 17 minutes of oper-
ation depending on the outside
temperature.
Switch on the ignition (
page 39).
Activating

Press button F on the automatic cli-
mate control panel (
page 185).
The indicator lamp on the button
comes on.Deactivating

Press button F (
page 185) once
more.
The indicator lamp on the button goes
out.
Warning!
G
Any accumulation of snow and ice should be
removed from the rear window before driv-
ing. Visibility could otherwise be impaired,
endangering you and others.
!
The rear window defroster cannot be
switched on when the retractable hardtop is
open. The indicator lamp will start flashing if the
hardtop is open.


Close the retractable hardtop.
The rear window defroster can then be switched
on.
!
If the rear window defroster switches off too
soon and the indicator lamp starts flashing, too
many electrical consumers are operating simul-
taneously and there is insufficient voltage in the
battery. The system responds automatically by
switching the rear window defroster off.
As soon as the battery has sufficient voltage, the
rear window defroster automatically switches
back on automatically.

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.

as well as the airflow volume control are
set to U and there is a high need for
cooling, MAXCOOL is activated.
“MAX COOL” appears on the temperature
controls 6 and b (
page 185).
This provides the fastest possible cooling
of the vehicle interior (when retractable
hardtop is closed).
