Flat Tire Monitor
M Engine dynamics control
In the event of a flat tire
The indicator lamp in the instru-
ment cluster will light up red in
the event of a flat tire with
ensuing loss in pressure. In addition, an
acoustic signal is sounded. To come to
an immediate stop, reduce speed, while
avoiding any sudden, jerky braking or
steering maneuvers.
Fix the flat tire using the M Mobility
system, refer to page 126.
Reset the indicator lamp: the red indi-
cator lamp has to be switched off
manually after putting on a new wheel.
At this point, hold the Flat Tire Monitor
button down until the indicator lamp
goes out. Reinitialize the system after-
ward.
The Flat Tire Monitor cannot alert
you to severe and sudden tire
damage caused by external factors.
Another factor which the Flat Tire
Monitor does not recognize is the
balanced and very gradual pressure
loss that takes place in all tires over an
extended period of time.<
Check the tire inflation pressure
on a regular basis and correct if
necessary, refer to page 24.
Under certain circumstances, there
may be false warnings or a delayed
detection of losses in pressure when
driving on snow-covered or slippery
road surfaces.
Performance-oriented driving (slip at
the drive wheels, high levels of lateral
acceleration) can also delay the
appearance of status reports in the Flat
Tire Monitor's display.<
System malfunctionAs long as there is still a malfunction,
the indicator lamp in the instrument
cluster will stay lit up yellow.
Please contact your BMW center for
additional information.
The system (sport-mode identification)
will cause the engine to respond spon-
taneously to the motion of the acceler-
ator pedal. Activating/deactivating
sport-mode identificationActivating: with the key in ignition key
position 2, press the sport button. The
indicator lamp will light up.

without any additional pressure on
the accelerator pedal when the system
is activated.<

again; the indicator lamp will go out.
The sporty-comfortable mode is deacti-
vated every time the engine is started.

Air conditionerDraft-free ventilation You can adjust the blower controls for
the upper body area to select the
optimum airflow rates and directions for
your personal requirements:
1 Rotary dials for opening and closing
the vent outlets through an infinitely
variable range
2 Lever for adjusting airflow direction
3 With the rotary dial you can adjust the
temperature of the outgoing air:
>Turn toward blue Ð colder
>Turn toward red Ð warmer.
MicrofilterA microfilter, which traps incoming dust
and pollen, has been installed in your
vehicle. Your BMW center will replace it
during routine maintenance. A substan-
tial reduction in airflow indicates that
the filter needs to be replaced early.

condensation1. Set the blower speed control for the
air supply rate to position 4

Automatic climate control
*
Tips for pleasant drivingUse the automatic system (switch on
AUTO button 7). Select the desired
interior temperature.
Detailed setting options are described
for you in the following sections.
You vehicle is set in such a
manner that, when you unlock the
vehicle with the remote control of your
personal key, your own personalized
setting for the automatic climate control
is initiated. The AUTO program assumes
the adjustment of the air distri-
bution and the air supply for you and Ð
in addition to that Ð adapts the temper-
ature to external influences (summer,
winter) to meet preferences you can
specify.
Individual air distribution
You can cancel the AUTO
program by selecting specific
distribution patterns to suit your
own individual requirements.
While the AUTO program is then deacti-
vated, the automatic air supply control
remains in operation. The system
directs air to the windows , the upper
body and into the footwells . You
can reactivate the automatic air supply
by pressing the AUTO button.
Temperature
The displayed temperatures are
reference values for the interior
temperature. We recommend 727
(+226) as a comfortable setting, even
if the air conditioner is on. When you
start the vehicle, the system ensures
that the selected temperature is
reached as quickly as possible. It then
maintains this temperature, regardless
of the season.
Air supply (blower)
By pressing the left or right side
of the button, you can vary the
air supply. This deactivates the auto-
matic air supply Ð the AUTO display
disappears from the panel. Neverthe-
less, the automatic air distribution
remains unchanged. You can reactivate
the automatic air supply by pressing the
AUTO button.
When you set the lowest blower speed
by pressing the left half of the button,
all of the displays are canceled: the
blower, heating and air conditioner are
switched off, and the air supply is
stopped. You can reactivate the system
by pressing any button for the auto-
matic climate control.
To defrost windows and remove
condensation
This program quickly removes
ice and condensation from the
windshield and side windows.

Microfilter, activated-charcoal
filterThe built-in microfilter removes dust
and pollen from the incoming air. The
activated-charcoal filter provides addi-
tional protection by filtering gaseous
pollutants from the outside air. Your
BMW center will replace the combined
filter as a standard part of your sched-
uled maintenance. A substantial reduc-
tion in air supply indicates that the filter
needs to be replaced early.
To actuate, press the button briefly with
ignition key in position 1 or higher.

Ski bag
*
The ski bag allows the safe and clean
transport of up to 4 pairs of standard
skis or up to two snowboards.
The length of the ski bag and the addi-
tional space provided in the luggage
compartment make it possible to carry
skis up to 6.8 ft long (2.1 0 m). Because
of the tapered shape of the ski bag, it
can only accommodate two pairs of
skis 6.8 ft long (2.1 0 m).
Loading1. Fold the center armrest outward.
Loosen the trim from the upper
Velcro¨ fastener and place it on the
armrest
2. Press button 1 downward and swing
the cover forward
3. Extend the ski bag between the front
seats. The zipper provides conve-
nient access to stored items. It may
be opened to allow the ski bag to dry
4. Press knob 2: the cover in the
luggage compartment is unlocked.
To store the ski bag, perform the above
steps in reverse sequence.
Securing the loadSecure the bag's contents by tightening
down the retaining strap at the buckle.
Please be sure that the skis are
clean before loading them into the
bag. Be careful to avoid damage from
sharp edges.<

Securing the cargo in the luggage
compartment >For small, light items, use the rubber-
lined non-skid side of the floor mat or
secure with a luggage compartment
net
* or elastic straps, refer to
page 36
>For large, heavy pieces, see your
BMW center for load-securing
devices
*. Lashing eyes (arrow) are
provided at the inner corners of the
luggage compartment for attaching
these load-securing devices.
Read and comply with the information
enclosed with the load-securing
devices.
A special luggage system is available
as an option for your BMW. Please
observe the precautions included with
the installation instructions.AnchorsAccess to the anchors:
To fold up the covers (arrow), please
use the tool which is provided with the
luggage system.Loading and driving notesBecause roof racks raise the center of
gravity of the vehicle when loaded, they
exercise a major effect on its handling
and steering response.
When loading, be sure to remember not
to exceed the approved roof weight,
the approved gross vehicle weight or
the axle loads. You will find the specifi-
cations under "Technical Data" on
page 138.
Make sure that the load is not too
heavy, and attempt to distribute it
evenly. Always load the heaviest pieces
first (on the bottom). Be sure that
adequate clearance is maintained for
raising the sliding/tilt sunroof, and that
objects do not project into the opening
path of the luggage compartment lid.
Secure the roof luggage correctly
and securely to prevent it from
shifting or being lost during driving
(danger for following traffic).<
Drive smoothly and avoid sudden
acceleration or braking. Do not corner
at high speeds.
