2012 BMW 335I cooling

Display in the instrument clusterThe READY display in the tach‐
ometer signals that the Auto
Start/Stop function is ready to
start the engine automatically.
Note
The engine is not switched off automatically in
the following situations:▷External temperature below approx. +37 ℉/
+3 ℃.▷The external temperature is high and auto‐
matic climate control is running.▷The passenger compartment has not yet
been heated or cooled to the required level.▷The engine is not yet at operating tempera‐
ture.▷The wheels are at a sharp angle or the steer‐
ing wheel is being turned.▷After driving in reverse.▷Fogging of the windows when the automatic
climate control is switched on.▷The vehicle battery charge is very low.▷The engine compartment lid is unlocked.▷The parking assistant is activated.▷Stop-and-go traffic.▷The transmission selector lever is in position
N or S/M.
Starting the engine
The engine starts automatically under the fol‐
lowing conditions:
▷Manual transmission:
The clutch pedal is pressed.▷Automatic transmission:
By releasing the brake pedal.
After the engine starts, accelerate as usual.
Safety mode
After the engine switches off automatically, it
will not start again automatically if any one of the
following conditions are met.▷The driver's safety belt is unbuckled and the
driver's door is open.▷The hood was unlocked.
Some indicator lamps light up for varying
lengths of time.
The engine can only be started via the Start/
Stop button.
Note
Even if driving away was not intended, the de‐
activated engine starts up automatically in the
following situations:
▷Excessive warming of the passenger com‐
partment when the cooling function is
switched on.▷The steering wheel is turned.▷Automatic transmission: the transmission
position is changed from D to N, R, or M/S.▷Automatic transmission: the transmission
position is changed from P to N, D, R, or M/
S.▷The vehicle begins rolling.▷Fogging of the windows when the automatic
climate control is switched on.▷The vehicle battery charge is very low.▷Excessive cooling of the passenger com‐
partment when the heating is switched on.▷Low brake vacuum pressure; this can occur,
for example, if the brake pedal is depressed
a number of times in succession.
Preventing an automatic engine stop
with automatic transmission
The concept
To make it possible to drive away very quickly,
such as at an intersection, the automatic engine
stop can be actively prevented.

Climate control functions in detail
Manual air distribution Turn the wheel to select the de‐
sired program.▷ Windows.▷ Upper body region.▷ Windows, upper body region, and foot‐
well.▷ Footwell.
Defrosting windows and removing
condensation
Direct the air distribution toward windows, in‐
crease the air flow and temperature, and, if nec‐
essary, use the cooling function.
Rear window defroster Press the button.
The rear window defroster switches off
automatically after a certain period of time.
Air flow, manual Press the left or right side of the button:
decrease or increase air flow.
The air flow of the air conditioner may be re‐
duced automatically to save battery power.
AUTO program Press the button.
Air volume, air distribution, and tem‐
perature are controlled automatically.
Depending on the selected temperature and
outside influences, the air is directed to the
windshield, side windows, upper body, and into
the footwell.
The cooling function, refer to page 135, is
switched on automatically with the AUTO pro‐
gram.
Temperature Turn the wheel to set the desired
temperature.
The automatic climate control reaches this tem‐
perature as quickly as possible, if necessary by
increasing the cooling or heating output, and
then keeps it constant.
Avoid rapidly switching between different tem‐
perature settings. The automatic climate control
will not have sufficient time to adjust the set
temperature.
Cooling function
The passenger compartment can only be
cooled with the engine running.
Press the button.
The air is cooled and dehumidified and
– depending on the temperature setting –
warmed again.
Depending on the weather, the windshield may
fog up briefly when the engine is started.
The cooling function is switched on automati‐
cally with the AUTO program.
When using the automatic climate control, con‐
densation water, refer to page 158, develops
that exits underneath the vehicle.
Recirculated-air mode
You can respond to unpleasant odors or pollu‐
tants in the immediate environment by tempo‐
rarily suspending the supply of outside air. The
system then recirculates the air currently within
the vehicle.
Press the button repeatedly to select
an operating mode:Seite 135Climate controlControls135

▷LED off: outside air flows in continuously.▷LED on, recirculated-air mode: the supply of
outside air into the vehicle is permanently
blocked.
If the windows fog over, switch off recirculated-
air mode and increase the air volume, if neces‐
sary.
Continuous recirculated-air mode
The recirculated-air mode should not be
used for an extended period of time, as the air
quality inside the vehicle deteriorates steadily. ◀
Switching the system on/off
Switching off Press the left button at the minimum
speed.
Switching on
Press any button except the seat heating but‐
tons.
Microfilter, recirculated air filter
The microfilter removes dust and pollen from
the incoming air.
The recirculated-air filter removes dust from the
interior air in recirculated-air mode.
These filters should be replaced during sched‐
uled maintenance of your vehicle., refer to

perature, maximum air flow and recirculated-air
mode.
Air flows out of the vents for the upper body re‐
gion. Open them for this purpose.
The air is cooled fastest when the engine is run‐
ning.
The air flow can be adjusted when the program
is active.

Automatic recirculated-air control/
recirculated-air mode
You can respond to unpleasant odors or pollu‐
tants in the immediate environment by tempo‐
rarily suspending the supply of outside air. The
system then recirculates the air currently within
the vehicle.
Press the button repeatedly to select
an operating mode:▷LEDs off: outside air flows in continuously.▷Left LED on, automatic recirculated-air con‐
trol: a sensor detects pollutants in the out‐
side air and controls the shutoff automati‐
cally.▷Right LED on, recirculated-air mode: the
supply of outside air into the vehicle is per‐
manently blocked.
If the windows are fogged over, switch off the
recirculated-air mode and press the AUTO but‐
ton to utilize the condensation sensor. Make
sure that air can flow onto the windshield.
Continuous recirculated-air mode
The recirculated-air mode should not be
used for an extended period of time, as the air
quality inside the vehicle deteriorates steadily. ◀

Parked-car ventilation
The concept
The parked-car ventilation ventilates the vehicle
interior and lowers its temperature, if necessary.
The system can be switched on and off at any
external temperature, either directly or by using
two preset switch-on times. It remains switched
on for 30 minutes.
Open the vents to allow air to flow out.
Operation can be performed via iDrive.
