ally.
Setting the ventilation
General
The direction of the air flows can be set for direct
or indirect ventilation.
Direct ventilation
Align the air flow directly onto the vehicle occu‐
pants. The air flow provides noticeable heating or
cooling depending on the set temperature.
Indirect ventilation
Do not align the air flow directly onto the vehicle
occupants. The vehicle interior is cooled or
heated indirectly depending on the set tempera‐
ture.

Climate
Independent ventilation
Principle
The independent ventilation allows the tempera‐
ture of the interior to be adjusted before the jour‐
ney starts. Depending on the set temperature
and ambient temperature, the interior is ventila‐
ted or heated using any available residual heat
from the engine.
General
The system can be switched on and off directly
or for a preselected departure time.
The system can also be used via the BMW Con‐
nected app.
The switch-on time is calculated based on the
outside temperature. The system will switch on
in good time before the preselected departure
time.

Vehicle is in idle or standby state and not in
drive-ready state.
Battery is sufficiently charged.
When activated, the independent ventilation
uses power from the vehicle battery. As a re‐
sult, the maximum activation time is restricted
to protect the battery. After the engine is
started or after driving a short distance, the
system will be available again.
Ensure that the date and time are set cor‐
rectly in the vehicle.
Open the side nozzles to allow the air to enter
the passenger compartment.
