Air conditioner
The air is cooled and
dehumidified and Ñ
depending on the temperature setting Ñ
warmed again when the air conditioner
system is switched on. Depending on
the weather, the windshield may fog
over briefly when the engine is started.
You can reduce condensation forming
on the windows by switching on the air
conditioner.
Condensation forms in the air
conditioner system during opera-
tion, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Maximum cooling
You will get maximum
cooling capacity using this
program if the engine is running and
the outside temperature is above
approx. +41 7(+5 6).
The temperature display 9 jumps to
+60 7 (+16 6), the system switches
over to the recirculated-air mode, and
the air streams out of the ventilation grill
with the maximum amount of flow. That
is why you need to keep these open if
you select this program.
Automatic recirculated-air
control (AUC)
If there are unpleasant
odors or pollutants in the
outside air, you can temporarily block
the airflow from the outside. The
system then recirculates the air
currently within the vehicle.
Press the button repeatedly to run
through the following control sequence:
>Indicator lamps off: outside air supply
operational
>Left-hand indicator lamp on Ð AUC
mode: the system recognizes pollut-
ants 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
automatic system then switches back
and forth between outside air supply
and recirculation of the air within the
vehicle
>Right-hand indicator lamp on: the
outside air supply into the vehicle is
completely blocked. The system then
recirculates the air currently within
the vehicle.
If you have a steering wheel with multi-
function buttons with the button for
recirculated-air mode (refer to page 22),
you can also use this button to switch
between "Off" and the recirculated-air
mode or AUC and the recirculated-air
mode.
If the windows fog over in the
recirculated-air mode, switch the
recirculated-air mode off and increase
the air supply as required.< Rear window defroster
When the rear window
defroster is activated,
the indicator lamp comes on. The
rear window defroster switches off
automatically.

Brake system Brake fluid levelIf the brake fluid level is too low and
brake pedal travel has become longer,
there may be a defect in one of the two
brake system's hydraulic circuits.
Proceed to the nearest
BMW Sports Activity Vehicle
center. Here increased pressure on the
brake pedal may be required, and slight
pulling to the side and longer braking
distances may result. Please remember
to adapt your driving style accord-
ingly.<
Disc brakesWhen the vehicle is driven only occa-
sionally, during extended periods when
the vehicle is not used at all, and in
operating conditions where brake appli-
cations are less frequent, there is an
increased tendency for corrosion of the
rotors and accumulation of contamina-
tion on the brake pads. This occurs
because the minimal pressure which
must be exerted by the pads to clean
the discs by brake applications is not
reached.
If the brake rotors are corroded, they
will tend to respond to braking with a
pulsating effect which even extended
application will fail to cure.
When driving in wet conditions and in
heavy rain, it is advisable to apply light
pressure to the brake pedal from time
to time. Watch traffic conditions to
ensure that this maneuver does not
endanger other road users. The heat
which is generated by the brake appli-
cations helps to dry the brake pads and
rotors. The braking force is then imme-
diately available when required.
Extended or steep mountain descents
should be driven in the gear in which
only minimal periodic brake application
is required. This avoids excessive strain on the brakes and possible impairment
of the braking effect.
Do not coast with the clutch
depressed or with the transmis-
sion or selector lever in neutral. Do not
drive with the engine switched off. The
engine provides no braking effect when
the clutch is depressed or the transmis-
sion is in neutral, and there is no
power-assist for braking or steering
when the engine is not running.
Have brake inspections performed at a
BMW Sports Activity Vehicle center
only. If you do not, parts of the four-
wheel drive system could be damaged.
Never allow floor mats, carpets or any
other objects to protrude into the area
around the accelerator, clutch and
brake pedals and obstruct their move-
ment.<
Brake pads
For your own safety: use only
brake pads that BMW has
released for your particular vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<
