switched on automatically with the AUTO pro‐
gram.
Convertible program
When the hardtop is open, the convertible pro‐
gram is activated as well. In the convertible
program, the automatic climate control is opti‐
mized for driving with the hardtop open. In ad‐
dition, the air flow is increased as the vehicle
speed increases.
The efficiency of the convertible program can
be greatly enhanced by installing the wind de‐
flector.
Temperature Turn the ring to set the desired
temperature.
The automatic climate control reaches this
temperature as quickly as possible, if needed
by increasing the cooling or heating output,
and then keeps it constant.

perature settings. Otherwise, the automatic cli‐
mate control will not have sufficient time to ad‐
just the set temperature.

engine running.
Press button.
The air will be cooled and dehumidi‐
fied and, depending on the temperature set‐
ting, warmed again.

side windows may fog up briefly when the en‐
gine is started.

cally with the AUTO program.Seite 146ControlsClimate control146
