If you open the driver's door when the ignition is
switched off, then the exterior lighting is
switched off if the light switch is in position0, 2,
or3.
Switch on the parking lamps as needed, switch
position1.
Parking lamps
In switch position1, the vehicle is lit on all sides.
You can use the parking lamps for parking.
The parking lamps will discharge the bat-
tery. For this reason, avoid using them for
extended periods; otherwise, it may no longer
be possible to start the engine. It is preferable to
switch on the one-sided roadside parking
lamps, refer to page60.<
Low beams
The low beams light up when the switch is in
position2 and the ignition is on.
Defective lamps
The indicator lamp lights up:
At least one bulb of the exterior lighting
on the vehicle is defective.
Replacing bulbs, refer to page112.
Door handle lighting
When the parking lamps or low beams are
switched on, the interior door handles are also
illuminated. The intensity of the lighting is
adjusted using the instrument lighting control.
Welcome lamps
If, when parking the vehicle, you leave the light
switch in position2 or3, the parking lamps and
the interior lamps light up briefly when the vehi-
cle is unlocked with the remote control.
Pathway lighting
When you activate the headlamp flasher after
parking the vehicle and switching off the lamps,
the low beams will come on for a brief period.
You may also have this function deacti-
vated if you wish.<
Daytime driving lamps*
If so desired, the light switch can remain in
position0, 1, or3.
In positions0 and3, after the ignition is
switched off, the exterior lighting is automati-
cally switched off. In position1, the parking
lamps are lit after the ignition is switched off.
The parking lamps can be switched on as
needed as described under Parking lamps.
You can have the daytime driving lamps
activated on your vehicle.<

Automatic headlamp control*
In switch position3, the low beams are
switched on or off automatically, for example in
tunnels, at dawn and dusk, and in the event of
precipitation. The Adaptive Head Light
* is acti-
vated.
When you enter a tunnel with bright ceiling
lighting, this can delay the switching on of your
low beams.
The headlamps can also come on when the sun
is low on the horizon in a blue sky.
The low beams remain switched on
regardless of the ambient light when you
switch on the front fog lamps
*.
When the daytime driving lamps are activated,
refer to page59, the low beam headlamps are
always switched on when the switch is in posi-
tion3 and the ignition is switched on.<
If so desired, the light switch can remain in
position3. The exterior lamps are automatically
switched off after the ignition is switched off.
Automatic headlamp control cannot
serve as a substitute for the driver's judg-
ment in determining when the vehicle lamps
should be switched on. For example, the sys-
tem cannot detect fog or hazy weather. To
avoid safety risks, you should always switch on
the low beams manually under these condi-
tions.<
You can have the sensitivity of the head-
lamp control adjusted.<
Adaptive Head Light*
The concept
Adaptive Head Light is a variable headlamp
control system that enables better illumination
of the road surface. Depending on the steering
angle and other parameters, the light from the
headlamp follows the course of the road.
In tight curves, e.g. serpentines, or when mak-
ing turns, up to a speed of approx. 43 mph/
70 km/h, a turning lamp is switched on and illu-
minates the inside of the curve.
Activating Adaptive Head Light
With the ignition on, turn the light switch to the
Automatic headlamp control position, refer to
page59.
The turning lamp is switched on automatically
depending on the steering angle or the turn sig-
nal position.
In order not to blind oncoming traffic, the Adap-
tive Head Light points toward the passenger
side when the vehicle is stopped. When driving
in reverse, only the turning lamp is active and
lights up the region on the outside of the curve.
Malfunction
The LED next to the symbol for automatic head-
lamp control flashes. Adaptive Head Light is
malfunctioning or has failed. Have the system
checked as soon as possible.

Roadside parking lamps, left or right*
You also have the option of lighting up just one
side of your vehicle when parking. When doing
so, be sure to comply with national regulations.
After switching off the engine, press the lever
up or down past the resistance point, arrow 3.
The roadside parking lamps drain the bat-
tery. For this reason, avoid using them for
extended periods; otherwise, it may no longer
be possible to start the engine.<

Front fog lamps*
Briefly press the button to switch on/off.
The parking lamps or low beams must
be switched on for the fog lamps to
operate. The green indicator lamp lights
up when the fog lamps are on.
If the automatic headlamp control is acti-
vated, the low beams will come on auto-
matically when you switch on the fog lamps.<
Instrument lighting
Turn the serrated dial to adjust the illumination
intensity.
Interior lamps
The interior lamps, footwell lamps*, door exit
lighting
* and courtesy lamps* are controlled
automatically.
With the courtesy lamps, LED lamps are located
in both exterior mirrors to illuminate the exterior
area before the front doors.
If you wish, you can have the interior
lamps switch on after you unlock the vehi-
cle mechanically. You may have this function
activated/deactivated if you wish.<
If the interior lamps remain switched on
after locking the vehicle, one of the doors
or the liftgate may not be completely closed.<
Switching interior lamps on and off
manually

Air volume
You can vary the air volume in
steps 1 through 4. The heating or
cooling output is more effective
with a higher air volume.
Switching system on/off
Turn air volume rotary switch to 0. This com-
pletely shuts off the blower and air conditioning
system and stops the flow of air.
To switch on the air conditioning system, set an
arbitrary air volume.
Temperature
To increase the temperature, turn
to the right, toward red.
For a lower temperature, turn the
rotary switch counterclockwise
toward blue.
Air distribution
You can direct air to flow onto the
windows , toward the upper
body and into the footwell .
Intermediate settings are possible.
Rear window defroster
The rear window heating switches
off automatically after a certain
amount of time. Depending on
your equipment package, the upper wires are
used as an antenna and are not part of the rear
window defroster.
Switching cooling function on/off
When the cooling function is on,
the air is cooled, dehumidified, and
then reheated depending on the
temperature setting. This function is only avail-
able with the engine running.
The cooling function helps to prevent conden-
sation from forming on the windows or to
remove it quickly.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
Recirculated-air mode
You can respond to unpleasant
odors outside the vehicle by tem-
porarily suspending the supply of
outside air. The system then recirculates the air
currently within the vehicle.
If condensation starts to form on the
inside window surfaces during operation
in recirculated-air mode, you should switch it off
and increase the air supply as needed.
The recirculated-air mode should not be used
over a sustained period of time; otherwise, the
air quality inside the vehicle will steadily deteri-
orate.<

A congenial climate
For almost all conditions, the AUTO pro-
gram12 offers the optimum air distribution and
air volume, refer to AUTO program below. You
need only select an interior temperature 5 that
you find pleasant.
The following sections contain more detailed
information on the available setting options.
Your vehicle has been designed to auto-
matically select your personal climate-
control settings whenever you unlock the doors
using your individually programmed remote
control.<
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. It also adapts your instructions for the air
volume and temperature to outside influences
throughout the year, e.g. solar radiation or win-
dow condensation.
The cooling function is switched on automati-
cally along with the AUTO program.
Manually switching air distribution
on/off
You can direct air to flow onto the
windows , toward the upper
body and into the footwell .
You can reactivate the automatic
air distribution mode by selecting
the AUTO button.
Temperature
Set the desired temperature.
The automatic climate control
assures that this temperature is
reached as quickly as possible any
time of year, using maximum cool-
ing or heating capacity as needed, and then
keeps this temperature constant.The highest setting produces the maximum
heat output regardless of the outside tempera-
ture. The lowest setting activates maximum air
conditioning.
When you change between different tem-
perature settings in rapid succession, the
system does not have enough time to achieve
the desired temperature.<
Manually adjusting air volume
By pressing the lower button, you
can reduce the air volume. You can
increase it by pressing the upper
button.
You can reactivate the automatic
air volume mode by pressing the AUTO button.
Switching system on/off
At the lowest fan speed, press the lower button
to turn off the automatic climate control com-
pletely. All displays disappear.
Press any button to turn the automatic climate
control back on again.
Defrosting windows and removing
condensation
Quickly removes ice and conden-
sation from the windshield and
front door windows.
Also switch on the cooling function.
Switching cooling function on/off
When the cooling function is on,
the air is cooled, dehumidified, and
then reheated depending on the
temperature setting. This function is only avail-
able with the engine running.
The cooling function helps to prevent conden-
sation from forming on the windows or to

AUC Automatic Recirculated-air
Control/recirculated air mode
You can set the desired operating
mode by pressing the button
repeatedly:
>LEDs off: outside air continuously flows into
the vehicle.
>Left LED on, AUC mode: a sensor detects
pollutants in the outside air. The system
suspends the supply of outside air as
needed and recirculates the air currently
within the vehicle. As soon as the concen-
tration of pollutants in the outside air has
decreased sufficiently, the system switches
automatically back to supplying outside air.
>Right LED on, recirculated-air mode: the
outside air supply into the vehicle is shut off
continuously. The system then recirculates
the air currently within the vehicle.
If the windows fog over in recirculated-air
mode, then press the AUTO button or
switch off the recirculated air mode and
increase the air volume as needed.
The recirculated-air mode should not be used
over a sustained period of time; otherwise, the
air quality inside the vehicle will steadily deteri-
orate.<

Microfilter/activated-charcoal filter*
The microfilter removes dust and pollen from
the incoming outside air. The activated-char-
coal filter provides additional protection by fil-
tering gaseous pollutants from the outside air.
This combined filter is replaced when mainte-
nance is performed by your BMW Sports Activ-
ity Vehicle Center. A substantial reduction in
air supply indicates that the filter should be
replaced before normal maintenance.
