Microfilter/activated-charcoal filter
The microfilter removes dust and pollen
from the incoming air. The activated-char-
coal filter provides additional protection by
filtering gaseous pollutants from the out-
side air. Your BMW center replaces this
combined filter as a standard part of your
scheduled maintenance.
You can select a display of more detailed
information in the Service Interval Display,

Rear air conditioner*
The following settings and operating
modes can be selected and adjusted sep-
arately on the left and right sides:
1Adjusting cooling
2Maximum cooling
3Adjusting air supply manually
4Switching off rear air conditioner
Switching on rear air conditioner
To switch on the rear air conditioner
>select maximum cooling 2
>press the OFF button 4 again
>in the Control Center, select "Rear air
cond." and confirm, refer to Switching
on/off using the Control Center.
When you switch on the rear air con-
ditioner, you simultaneously switch
on the rear cooler, refer to page 113.<
Adjusting cooling
You can also set the system to
provide the desired level of
cooling by turning. We recom-
mend setting the system for
moderate cooling. When you
start the vehicle, this system ensures that
the selected setting is achieved as quickly
as possible. It then maintains this tempera-
ture, regardless of the season.
Adjusting air supply manually
You can adjust the air supply by
turning.
Maximum cooling
This program quickly provides
maximum cooling.
The system automatically switches to the
recirculated-air mode while a high-speed
stream of air simultaneously emerges from
the vent outlets. For this reason you should
ensure that these outlets are open before
selecting this program.
Switching off rear air conditioner
The air conditioner is switched
off.
Press the button again to switch back on.

to as hydroplaning, and is characterized
by a partial or complete loss of contact
between tires and road surface, ultimately
undermining your ability to steer and brake
the vehicle.<
Driving through water
Do not drive through water on the
road if it is deeper than 1 ft/30 cm,
and then only at walking speed at the most.
Otherwise, the vehicle's engine, the electri-
cal systems and the transmission may be
damaged.<
Brake system
Braking with ABS
The best way to achieve the best response
from the ABS is to apply maximum pres-
sure to the brake pedal Ð panic stop. Since
the vehicle maintains steering responsive-
ness, you can nevertheless avoid possible
obstacles with a minimum of steering
effort.
Pulsation at the brake pedal combines with
sounds from the hydraulic circuits to indi-
cate to the driver that ABS is in its active
mode.
Do not drive with your foot resting on
the brake pedal. Otherwise, even light
but consistent pedal pressure can lead to
high temperatures, brake wear and possi-
bly even brake failure.<
Disc brakes
Driving in wet conditions
While driving in wet conditions and in
heavy rain, it is a good idea to apply light
pressure to the brake pedal every few
miles. Monitor traffic conditions to ensure
that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to
ensure that full braking efficiency will then
be available when you need it.
Hills
You can retain full and unimpaired braking
efficiency by downshifting to a gear in
which only minimal brake applications are
needed when descending long or steep
downhill stretches.
You can further enhance the engine's
braking effect by selecting a lower gear
in the automatic transmission's manual
mode, downshifting as far as first gear
on extremely steep stretches, refer to
page 67. This strategy helps you avoid
placing excessive loads on the brake sys-
tem.
Never allow the vehicle to coast with
the transmission in Neutral Ð or with
the engine switched off Ð as there is no
engine braking when the transmission is in
Neutral, and no power-assist for brakes
and steering when the engine is not run-
ning.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
accelerator and brake pedals and obstruct
their movement.<
Corrosion
When the vehicle is driven only occasion-
ally, during extended periods when the
vehicle is not used at all, and in operating
conditions where brake applications are
less frequent, there is an increased ten-
dency for corrosion to form on rotors, while
contaminants accumulate on the brake
pads. This occurs because the minimal
pressure which must be exerted by the
pads during brake applications to clean the
rotors is not reached.
Should corrosion form on the brake rotors,
the brakes will tend to respond with a pul-
sating effect that even extended applica-
tion will fail to cure.
Brake pads
If the brake pad wear warning lamp
appears in the Check Control,
accompanied by a text. Please take
careful note of the additional information on
the Control Display.
