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.
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.<

Ventilation
1Knurled wheels for opening and closing the
air vents through an infinitely variable range
2Levers for changing airflow direction
3Knurled wheel for more or less cool air from
the air vents for the upper body region
Ventilation for cooling
Adjust the vents to direct the flow of cool air in
your direction, for instance, if the interior has
become too warm.
Draft-free ventilation
Set the vent outlets so that the air flows past
you and is not directed straight at you.
Microfilter
The microfilter removes dust and pollen from
the incoming outside air. It is replaced when
maintenance is performed by your BMW Sports
Activity Vehicle Center. A substantial reduction
in air supply indicates that the filter should be
replaced before normal maintenance.

A congenial climate
For almost all conditions, the AUTO program 12
offers the optimum air distribution and air vol-
ume, 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. Depending on the
weather, the windshield may fog over briefly
when the engine is started.
The cooling function is automatically switched
on along with the AUTO program. It is only pos-
sible to cool the passenger compartment when
the engine is running.

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.<

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.

become too warm.
Draft-free ventilation
Set the vent outlets so that the air flows past
you and is not directed straight at you.
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.

Coolant
Warning lamp
The warning lamp lights up: coolant
level is too low; top off at the next
opportunity.
Do not open the cooling system when the
engine is hot. Escaping coolant can cause
burns.<
Coolant consists of water and coolant additive.
Not all commercially available additives are suit-
able for your BMW. Ask your BMW Sports
Activity Vehicle Center for suitable additives.
Only use suitable additives; otherwise,
engine damage may result. The additives
are harmful to your health, so follow the instruc-
tions on the containers.<
Always observe all applicable environ-
mental laws and regulations when dis-
posing of used coolant additives.<
Checking coolant level
1.Allow engine to cool.
2.Turn the cap of the expansion tank counter-
clockwise to allow any accumulated pres-
sure to escape, then continue turning to
open.
3.The coolant level is correct when it is
between the MIN and MAX marks, also refer
to illustration next to filler neck.
4.If the coolant is low, slowly add coolant up to
the specified level – do not overfill.
5.Screw on the cap and tighten snugly.
6.Have the reason for the coolant loss cor-
rected as soon as possible.
Brake system
Malfunction
Brake fluid
The warning lamp lights up red despite
the handbrake being released.
The brake fluid in the reservoir has
fallen to below the minimum level. At the same
time, a considerably longer brake pedal travel
may be noticeable. Have the system checked
immediately.
During continued driving, increased brake
pedal travel may be necessary, and con-
siderably longer braking distances may result.
Please adapt your driving style accordingly.<
