repeatedly to run through the following
control sequence:
>Indicator lamps off: outside air flows
into the vehicle
>Left-hand indicator lamp on Ð AUC
mode: the system recognizes pollutants
in the outside air and blocks the flow of
air when necessary. The system then
recirculates the air currently within the
vehicle.
Depending on the air quality, the auto-
matic system then switches back and
forth between outside air supply and
recirculation of the air within the vehicle
>Right-hand indicator lamp on: the out-
side air supply into the vehicle is com-
pletely blocked. The system then recir-
culates the air currently within the
vehicle.
If condensation starts to form on the
inside window surfaces during opera-
tion in the recirculated-air mode, you
should switch it off while also increasing air
supply as required. The recirculated-air
mode should not be used over a sustained
longer period of time, as the air quality
inside the vehicle deteriorates.<
Rear window defroster
When the rear window
defroster is activated,
the indicator lamp comes on.
The rear window defroster switches off
automatically.
You can have your vehicle adjusted in
such a way that the rear window
defroster switches on automatically. It is
then switched on at outside temperatures
of less than approx. +46/397within
5 minutes of the engine start.<
Ventilation
The air vents for the upper body area can
be adjusted:
1Serrated dials for opening and closing
the vent outlets through an infinitely-
variable range
2Selector levers for airflow direction
3Use the serrated dial 3 to adjust the
amount of cool air that is added to the
airflow emerging from the vent outlets
for the upper body
Ventilation for cooling
Adjust the vents to direct the flow of cool
air in your direction, for instance, if the inte-
rior has become too warm, etc.
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 built-in microfilter removes dust and
pollen from the incoming air. The activated-
charcoal filter provides additional protec-
tion by filtering gaseous pollutants from the
outside air. This combined filter is replaced
when maintenance is performed by your
BMW Sports Activity Vehicle Center. A
substantial reduction in air supply indicates
that the filter must be replaced before nor-
mal maintenance.

Checking coolant level and topping
up coolant
Check the coolant level with the engine
cold, approx. 687/206:
1.Turn the cap of the expansion tank
counterclockwise to allow any accumu-
lated pressure to escape, then continue
turning to open
2.The coolant level is correct if the upper
end of the red float bar is at least at the
same height as the top edge of the filler
neck, refer to arrow. The bar end may
only protrude by a maximum of i in/
2 cm, i.e. up to the second mark on the
float bar, refer also to sketch beside the
filler neck
3.If necessary, add coolant. Slowly add
coolant until the correct level is reached
Ð do not overfill.
Always observe all applicable rules
and regulations for environmental
protection when disposing of used anti-
freeze and anticorrosion agents.<
Brake system
Malfunction
Brake fluid
The warning lamp lights up red
despite the handbrake being
released: stop immediately.
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. Contact the nearest
BMW Sports Activity Vehicle Center.During continued driving increased
brake pedal pressure may be neces-
sary, and considerably longer braking dis-
tances may result. Please adapt your driv-
ing style accordingly.<
Warning lamp for Canadian models.
Brake pads
The indicator lamp comes on.
The brake pads have reached their
minimum pad thickness. See your
BMW Sports Activity Vehicle Center imme-
diately to have the pads replaced.
For your own safety: use only brake
pads that BMW has released for your
particular vehicle model. As BMW cannot
assess the suitability of other brake pads
for use on your vehicle, we are unable to
assume continued responsibility for the
vehicle's operating safety if non-approved
pads are installed.<

tem, refer to page 77.

Maintenance
The BMW maintenance
system
The BMW maintenance system is designed
in such a way that it reliably ensures the
road safety and operating reliability of the
vehicle Ð keeping the cost for you as low as
possible.
Regular maintenance is not only required
for the safety of the vehicle, it also
improves the resale value.
Service Interval Display
The BMW Maintenance System takes the
driving conditions of the vehicle into
account when determining service inter-
vals:
From the point of view of maintenance,
62,000 miles/100,000 km accumulated in
short-distance urban driving are not the
equivalent of the same distance covered at
moderate speeds in long-distance high-
way travel.
The BMW maintenance system is divided
into engine oil service as well as Inspec-
tions I and II.
Determining the maintenance intervals
according to the actual loads on the vehi-
cle covers every kind of operating situa-
tion. However, even those who drive only
short distances Ð significantly less than
6,200 miles/10,000 km annually Ð should
have the engine oil changed at least every
2 years since oil deteriorates over time,
regardless of use.Brake fluid is hygroscopic: it absorbs
moisture from the atmosphere over
the course of time. To ensure that the brake
system continues to provide safe and reli-
able performance, remember to have the
brake fluid changed every two years at the
latest by a BMW Sports Activity Vehicle
Center, also refer to page 46 and to the
Service and Warranty Information Booklet
for US models or the Warranty and Service
Guide Booklet for Canadian models.<
Service and Warranty Information
Booklet for US models/Warranty and
Service Guide Booklet for Canadian
models
For detailed information on required main-
tenance items and the work involved,
please refer to the Service and Warranty
Information Booklet for US models or to the
Warranty and Service Guide Booklet for
Canadian models.
Depending on operating conditions, it may
be advisable to have the body checked for
damage from rocks or gravel as a precau-
tion against corrosion.
BMW recommends that you have
your BMW Sports Activity Vehicle
Center perform the maintenance and
repair.
Check that the maintenance work is
recorded in the Service and Warranty
Information Booklet for US models or the
Warranty and Service Guide Booklet for
Canadian models. These entries will serve
as proof that the vehicle has received reg-
ular maintenance.<
