Rear outlet vents (F)
The rear outlet vents are controlled by the rear climate control system.
However, external conditions and manual settings also have influences on the
actual operation of the rear outlet vents by blocking air flows or changing air
flow volumes.
The rear outlet vents may blow slightly cooler air when the heater is operat-
ing due to some heat loss through the air ducts from the front of the vehicle.
To prevent this, the rear outlet vents may not blow any air immediately after a
cold start when the outside temperature is detected to be extremely low in
winter and the engine has not sufficiently warmed up.
Side outlet vents (D)
G90 is equipped with temperature sensors inside the side outlet vents to
accurately measure and control air temperature both in the driver’s seat and
the front passenger’s seat. However, when the side outlet vents are closed,
the temperature sensor will measure air temperature only inside the side out-
let vents. For accurate temperature control, open the side outlet vents.

Front mode selection button
The mode selection button controls
the direction of the air flow through
the ventilation system.
The air flow outlet port is converted
as follows:

floor air vents to help provide pleas-
ant air quality inside the passenger
compartment.
Bi-Level (B, C, D, E, F, G)
Air flow is directed towards the face
and the floor.
