ComputerAfter three incorrect code entries,
or three attempts to start the engine
without a code entry, the alarm will
sound for 30 seconds on vehicles
equipped with an alarm system.
Setting the alarm in an emergency:
If you have forgotten the code, proceed
as follows:
1. Disconnect the battery, wait about
2 minutes, then reconnect it. Note
that on vehicles with an alarm
system, the alarm will sound
2. Turn the ignition key to position 1:
The time display will count down for
the next ten minutes
3. After ten minutes, start the engine.
If the code becomes available
again in the meantime, it can be
entered during the waiting period after
pressing the CODE button.<
Remote controlYou can press the button in the turn
signal indicator lever to retrieve infor-
mation from the computer for display.
To do this, press:
>The button on the lever until PROG 1
shows on the display
>The MID buttons in the order in which
you wish the information to be dis-
played.
Each time an entry is stored, the pro-
gram number appears on the display.
To terminate the selection procedure:
Press the right side of the button.39mde118
To display all the available information,
press:

Park Distance Control (PDC)
*
PDC does not remove the driver's
personal responsibility for evalu-
ating the distance between the vehicle
and any obstacles. Even with the sen-
sors, there is a blind spot in which
objects cannot be detected. This
applies especially in those cases where
the system approaches the physical
limits of ultrasonic measurement, as
occurs with e. g. tow bars and trailer
couplings, and in the vicinity of thin or
wedge-shaped objects.
Certain sources of sound, such as a
loud radio, could drown out the PDC
signal tone.<
Keep the sensors clean and free
of ice or snow in order to ensure
that they will continue to operate effec-
tively.
Do not apply high-pressure spray to the
sensors for a prolonged period of time.
Maintain an adequate distance of more
than 4 in (10 cm).<

M Dynamic Driving ControlThe system guarantees that whenever
desired, the system will switch the Ser-
votronic and the accelerator pedal
response from the sporty-comfortable
mode to a pure performance mode.
This means that steering response
becomes more performance-oriented
and the response of the accelerator
pedal is much more spontaneous (Per-
formance Recognition). 39mde125
Performance Recognition Press the button with the ignition key in
position 2: the indicator lamp comes
on.
Deactivating Performance Recognition:
Press the button again; the indicator
lamp goes out.
The coordinated performance-comfort
mode is activated automatically each
time you start the engine.

Flat Tire MonitorFlat tireIn the event of a flat tire, the message,
"TIRE DEFECT" will appear in the
Check Control. This visual alert will be
accompanied by a gong.
If this occurs, reduce vehicle speed
immediately and stop the vehicle. Avoid
hard braking and overcorrecting at the
steering wheel.
Correct the flat tire using the M Mobility
system (refer to page 128).
The Flat Tire Monitor cannot alert
you to severe and sudden tire
damage caused by external factors.
Another factor which the Flat Tire Mon-
itor 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 22.
Do not carry out any kind of system
activation when using snow chains.
Under these kinds of conditions, false
warnings and unidentified losses in
pressure are possible.
In certain circumstances, when driving
on snow-covered or slippery road sur-
faces, there may be a delay in identi-
fying any loss in inflation pressure.
Performance-oriented driving (slip at
the drive wheels, high levels of lateral
acceleration) can also delay the appear-
ance of status messages in the Flat Tire
Monitor's display panel.<
System malfunctionsThe message "TIRECONTROL INAC-
TIVE" appears in the Check Control
and remains on until the problem is cor-
rected.
The same message is displayed if there
is a system malfunction.
Please refer the problem to your BMW
center.

Automatic climate controlTips for pleasant drivingUse the automatic system (switch on
with AUTO button 6). Select an interior
temperature that you find comfortable.
The following description will lead you
through additional individual settings.
Your BMW center can program
the settings of your vehicle in such
a manner that, when you unlock the
vehicle with your individualized key,
your own personalized setting for the
automatic climate control is initiated. The AUTO program
assumes the adjustment of
the air distribution and the air supply for
you and Ð in addition to that Ð adapts
the temperature to external influences
(summer, winter) to meet preferences
you can specify.
Individual air distribution
You also have the option of
individually configuring the
air distribution pattern to
suit your own personal pref-
erences. While the AUTO
program is then deactivated, the auto-
matic airflow control remains in opera-
tion. The system directs air to the win-
dows , the upper body and into
the footwells . You can reactivate the
automatic air distribution mode by
selecting the AUTO button.
Temperature
You can make individual
temperature settings on the
driver's side or the front
passenger side. The figures in the dis-
play provide a general indication of
interior temperature. We recommend a
setting of 72 7 (22 6) for a congenial
interior climate, even when the air con-
ditioner is in operation. When you start
the vehicle, the system ensures that the
selected temperature is achieved as
quickly as possible. It then maintains
this temperature, regardless of the
season.
Air supply
In the AUTO program, the
airflow is controlled auto-
matically. AUTO will appear in display 9,
refer to the overview on page 87.
Use "+" and "Ð" to vary the airflow.
Your setting is displayed with bars and
the automatic air supply is switched off.
The automatic air distribution setting is
maintained. You can reactivate the
automatic air supply by pressing the
AUTO button.
When you press "Ð" during operation at
the lowest blower speed, all displays
are canceled: the blower, heating and
air conditioning are switched off. The
outside air supply is deactivated. By
pressing the desired button on the
automatic climate control (except MAX
button 16), you can switch the system
back on.
To defrost windows and remove
condensation
This program quickly
removes ice and conden-
sation from the windshield and the side
windows.

Automatic climate control Draft-free ventilation You can adjust the vent outlets for the
upper body area for optimal personal
comfort:
1 Rotary dials for infinitely-variable
opening and closing the vent outlets
2 Rotary levers for airflow direction
3 Rotary dial allows you to control the
temperature of the airflow as desired:
>Turn toward blue Ð colder
>Turn toward red Ð warmer.390de685

way as the front dial to adjust the

Microfilter, activated-charcoal
filter The microfilter removes dust and pollen
from the incoming air. The activated-
charcoal filter provides additional pro-
tection by filtering gaseous pollutants
from the outside air. Your BMW center
replaces this combined filter as a stan-
dard part of your scheduled mainte-
nance. A substantial reduction in airflow
indicates that the filter must be
replaced before scheduled mainte-
nance.
