Independent Ventilation - BMW 318i Owner's Handbook Manual

Switching cooling function on/off
When the cooling function is on, air
is cooled and dried, then reheated
according to the temperature set-
ting. Depending on weather conditions, the
windscreen may fog over momentarily when
the engine is started.
The cooling function is switched on automati-
cally with the AUTO program. The passenger
compartment can only be cooled if the engine is
running.
Rear window heating
The heater is switched off auto-
matically after a certain time.
Depending on the equipment ver-
sion, upper wires are used as an aerial and are
not part of the rear window heating.
Ventilation
1 Knurled wheels to open and close the air
outlets continuously
2 Levers for changing the direction of the air-
flow
3 Knurled wheel for more or less cool air via
the air outlets for the upper body
Ventilation for cooling
Adjust the outlets so that cool air is directed
towards you, e.g. if the car's interior has
become hot.
Draught-free ventilation
Adjust the outlets so that the airflow passes the
occupants without striking their bodies directly.

Ventilation in the rear
1 Knurled wheel to open and close the air out-
lets continuously
2 Knurled wheel to adjust the temperature:
> Turn towards blue: cooler
> Turn towards red: warmer
3 Levers for changing the direction of the air-
flow
Micro-filter/activated charcoal filter
The micro-filter traps dust and pollen in the
incoming air. The activated charcoal filter in
addition removes gaseous pollutants from the
air entering the car. This combined filter is
changed by BMW Service during routine main-
tenance work.

Independent ventilation*/

heating system*
The principle
The independent ventilation system ventilates
the passenger compartment and lowers its
temperature under some circumstances.
The independent heating system warms up the
passenger compartment; snow and ice can be
removed more easily.
Two different switch-on times can be pre-
selected. The systems can also be switched on
or off directly or via the remote control. They
remain switched on for 30 minutes.
Due to their high power consumption, you
should not switch on the systems twice in a row
without first letting the battery recharge while
the vehicle is being driven.
