BMW Night Vision*
The concept
BMW Night Vision is a driver assistance system
that is designed to provide enhanced vision for
certain objects at night. This can be especially
helpful for detecting people and larger animals.
When objects are detected, the driver may be
able to take appropriate action sooner. For
example, the driver may identify and detect the
presence of persons or animals in the road
ahead or off to the sides and can be more alert,
slow down or stop, blow the horn, etc. The
driver can decide which actions are appropriate
and then react accordingly.
A certain area in front of the vehicle is viewed by
an infrared camera and a generated image is
shown on the Control Display. The resulting
thermal image shows the relative heat radiation
of the objects present in the camera's field of
view. Warmer objects appear brighter and
cooler objects appear darker. Contrast is
dependent on the temperature difference
between the objects and the background and
on the amount of heat radiation of the object
itself. As a result, it is quite possible that a per-
son is not continually recognizable as a person
in shape, since the thermal radiation can be
affected by different clothing which blocks heat
loss. Objects with little temperature difference
to the surrounding area, or little heat radiation
are less noticeable, for example in cold weather.Any improvement in detection depends on
many factors such as the object size and tem-
perature compared to the surroundings, or
other nearby objects, the visual recognition
skills of the driver, weather conditions, and
other factors.
Driving hints
With the system active, periodically but briefly,
glance at the thermal image on the Control Dis-
play to notice objects that could be people or
larger animals. The glance should be similar to
glancing at the rear view mirror. Do not stare at
the image for long periods while driving, as this
will take your attention away from the road. If
you notice an object of interest ahead, be pre-
pared to slow down or stop, blow the horn, or
take other appropriate action.
System limits
The system is designed to supplement but not
replace forward vision through the windshield.
The driver is responsible for safe driving at
night. BMW Night Vision is not designed to be
used as a continuous viewing window for driv-
ing at night.
No system, no matter how sophisticated, can
operate without limitations. BMW Night Vision
operation is subject to physical and environ-
mental limitations that will reduce the ability of
the system to detect and display a clear thermal
image. Some of the situations in which these
limitations can occur are:
>on steep hilltops or depressions and in tight
curves
>in tunnels, as the contrast is inherently low
>when the camera lens is dirty

A congenial climate
For almost all conditions, the AUTO program1
offers the optimal air distribution and air vol-
ume. Select an interior temperature you find
pleasant.
The following section contains more detailed
information on the available setting options.
The settings are stored for the remote key cur-
rently in use.
AUTO program
The AUTO program handles the
adjustment of air distribution to the
windshield and side windows, in
the direction of the upper body, and in the foot-
well, as well as the adjustment of the air volume. It also adapts your instructions for the tempera-
ture to outside influences throughout the year.
The cooling is switched on automatically with
the AUTO program. At the same time, a con-
densation sensor controls the program so as to
prevent window condensation as much as pos-
sible.
Intensity of AUTO program
You can adjust the intensity of the AUTO pro-
gram by repeatedly pressing the AUTO button.
If you briefly press the button, the current set-
ting is displayed in the lower status line of the
Control Display.

menu.
2.Move the controller toward "Climate".
3.Turn the controller to select driver's side or
passenger side.
4.Turn the controller to select the field.
5.Press the controller repeatedly until the
desired program is displayed:
>"low"
>"medium"

Automatic recirculated air control/
recirculated air mode
You can respond to unpleasant
odors or pollutants in the immedi-
ate environment by temporarily
suspending the supply of outside air. The sys-
tem then recirculates the air currently within the
vehicle. In AUC mode, a sensor detects pollut-
ants in the outside air and controls the shut-off
automatically.
Press the button repeatedly to run through the
following control sequence:
>LEDs off: outside air flows into the vehicle
continuously.
>Left LED on, AUC mode: the system
detects pollutants in the outside air and
responds by blocking the supply of outside
air when required.
>Right LED on, recirculated-air mode: the
supply of outside air into the vehicle is con-
tinuously blocked.If condensation starts to form on the
inside window surfaces during operation
in the recirculated-air mode, you should switch
it off while also increasing air supply as
required. Make sure that air can flow to the
windshield, e.g. by pressing the AUTO button.
The recirculated-air mode should not be used
over a longer period of time, as the air quality
inside the vehicle deteriorates continuously.<
Switching off automatic climate control
The air volume, the heater, and the
air conditioner mode are all
switched off.
You can restart the automatic climate control by
pressing any of its buttons except the REST
button.
Temperature adjustment
You can turn to select the desired
temperatures for the driver's and
passenger sides. Your settings
appear on the status line of the
Control Display. The number
shown in the display provides a general indica-
tion of interior temperature.
The automatic climate control adjusts this tem-
perature as quickly as possible at any time of
year, if necessary with the maximum cooling or
heating capacity, and then keeps it constant.
When switching between different tem-
perature settings in rapid succession, the
automatic climate control does not have suffi-
cient time to achieve the set temperature.<
Using iDrive
1.Open the start menu.
2.Open "Climate".
3.Turn the controller to select driver's side or
passenger side.
4.Turn the controller to select the field and
press the controller.

6.Press the controller to save the setting.
Maximum cooling
Maximally cooled air is obtained as
quickly as possible from an outside
temperature above 327/06 and
with the engine running.
The automatic climate control
changes over to the lowest temperature and
switches into the recirculated-air mode. The
maximum air quantity only flows out of the vents
for the upper body, so open these vents for
maximum cooling.
Air volume
You can vary the air volume by
turning. You can reactivate the
automatic air supply mode by
pressing the AUTO button.
Manual air distribution
You can adapt the air distribution to your own
personal preferences:
1.Open the start menu.
2.Open "Climate".
3.Turn the controller to select driver's side or
passenger side.4.Select the desired field and press the con-
troller.

side windows
2Air to the upper body
3Air to footwell
You can only use the condensation sensor in
the AUTO program. Press the AUTO button
when you notice condensation on windows and
want to use the advantages of the condensation
sensor.
Defrosting windows and removing
condensation
Quickly remove ice and condensa-
tion from the windshield and front
side windows.
Residual heat
The system uses the warmth
stored in the engine to heat the
interior when the ignition is off, e.g.
while the vehicle is stopped at a
railroad crossing.
The function can be switched on when the fol-
lowing conditions are met:
>up to 15 minutes after switching off the
engine
>with the engine at operating temperature
>with sufficient battery voltage
>at an outside temperature below 777/
256
The LED lights up when the function is
switched on.

ready state.
Switching cooling function on and off
manually
When activated, the air conditioner
mode cools and dehumidifies the
incoming air, reheating it as
required, depending on the temperature set-
ting. Depending on the weather, the windshield
may fog over briefly when the engine is started.
The cooling function is switched on automati-
cally with the AUTO program. The passenger
compartment can only be cooled with the
engine running.
Rear window defroster
The rear window defroster
switches off automatically after a
while.
Front ventilation

Microfilter/activated-charcoal filter
The microfilter removes dust and pollen from
the incoming air. The activated-charcoal filter
provides additional protection by filtering gas-
eous pollutants from the outside air. Your BMW
center replaces this combined filter as a stan-
dard part of your scheduled maintenance.
