the following situations:
 Excessive warming of the
car's interior when the air con-
ditioning is switched on.

Depending on the vehicle equip- ment and country-specific ver-
sion, the vehicle features a
variety of sensors for assessing
the traffic situation. The Auto
Start/Stop function uses this
information to adapt to various
traffic situations in a proactive
manner.
For instance, this applies to the
following situations:

If a situation is detected in
which the stopping time is
expected to be very short, the
engine is not switched off
automatically. A message
appears on the Control Dis-
play, depending on the situa-
tion.
 If a situation is detected in
which the vehicle needs to
drive off immediately, the
engine is started automati-
cally.
The function may be restricted if
the navigation data is invalid,
outdated or not available, for
example.
The engine is not automatically
switched off.
The engine is started during an
automatic engine stop.

Do not rapidly switch between
different temperature settings.
Otherwise, the automatic air
conditioning will not have suffi-
cient time to adjust the set tem-
perature.
The air in the car's interior will
be cooled and dehumidified
and, depending on the tempera-
ture setting, warmed again.
The car's interior can only be
cooled with the drive-ready state
switched on. Air conditioning is switched on
with the engine running.
Depending on the weather, the
windshield and side windows
may fog up briefly when
drive-ready state is switched on.
The air conditioning is switched
on automatically with the AUTO
program.
When using the automatic air
conditioning, condensation
water develops and collects
underneath the vehicle.
The system is set to the lowest
temperature, optimum air flow
and recirculated-air mode with
the drive-ready state switched
on.
The function is available with
external temperatures above
approx. 32 °F/0 °C and with the
