Seat heating
*
Roller sun blind
*
The seat cushion and backrest can
be heated with the ignition key in posi-
tion 2.
You can call up different heating modes
by repeatedly pressing the keys.
When the three indicator lamps are illu-
minated, the highest heating mode is
activated. One lamp indicates the
lowest heating mode. The temperature
is regulated with a thermostat in each
mode.
You can also switch the higher heating
modes off directly:
Press and hold the button slightly
longer.460us285
To actuate, press the button briefly with
the ignition key in position 2.
The illustration depicts the arrangement
of the buttons if the vehicle is fully
equipped. This may vary, depending on
the equipment actually installed.460us286

HiFi system Ð harman kardonSpecial acoustical effects are activated
or deactivated every time you press the
button.
When the system is activated, the
impression of a significantly larger
passenger compartment is created at
all seating areas, together with an
improvement of the stereo effect.
When reception is weak, the system
frequently switches between stereo and
mono operation. Switch it off.460us287
To openPull the handle. The lamp comes on.To closeFold the cover up.To lockLock with one of the master keys.
A master key can also be used for
unlocking.
If you turn over only your door and
ignition keys for valet parking
(refer to page 32), for example, access
to the glove compartment is not
possible.<460de041
To prevent injury in the event of
a crash, close the glove compart-
ment immediately after use.<
Rechargeable flashlight

The flashlight is located on the left-
hand side of the glove compartment.
It features integral overload-protection
so it can be left in its holder continu-
ously.
Be sure that the flashlight is
switched off when it is inserted
into its holder. Failure to comply with
this precaution could lead to over-
charging and damage.<

Cigarette lighter

Ashtray, rear
Press the lighter in. Remove the lighter
as soon as it retracts.
Hold or touch the hot cigarette
lighter by the knob only. Holding
or touching it in other areas could result
in burns.
The cigarette lighter remains opera-
tional when the ignition key has been
removed. For this reason, children
should never be left in the vehicle unat-
tended. for flashlights, car vacuum cleaners,
etc., up to a rating of approx. 200 watts
at 12 volts. Avoid damaging the socket
due to inserting plugs of different
shapes or sizes.460de290
To openPush the cover open.To emptyPress on the edge of the raised cover in
the opening direction (arrow). You can
now pull the ashtray upward for
removal.460de104

Deceleration sensors continuously
monitor the acceleration forces acting
upon the vehicle. If, as the result of a
frontal collision, a deceleration is
reached at which the protection of the
safety belts alone is no longer
adequate, the gas generators of the
driver and passenger-front airbags are
ignited simultaneously. However, the
passenger-side airbag is only triggered
if an additional sensor has recognized
that the passenger seat is occupied.
In the event of a side collision, the head
protection and side airbags in the front
and rear
* are triggered if necessary.

The airbags located under the marked
covers inflate and unfold in a matter of
a few milliseconds. In this process, they
tear through the designed separation
points of the upholstered covers or
press them out.
Because the inflation process must be
virtually instantaneous, it is necessarily
accompanied by a certain amount of
ignition and inflation noise. The gas
required to inflate the airbags is not
dangerous, and the smoke associated
with it dissipates.
The entire process is completed within
fractions of a second.

Self-diagnostics All of the important electrical and elec-
tronic systems in the vehicle are tested
regularly and automatically Ð the driver
does not have to perform any extra
operations or adjustments.
The indicator lamps also come on
briefly after the ignition has been turned
on.
While you are driving, the functional
status of the actuator motors (for the
windshield wipers, power windows,
seats, sliding/tilt sunroof, etc.) is
constantly analyzed by current
measurements in their relays.460de177
In the same manner, the electrical
resistance of the airbag ignition genera-
tors and all of the remaining airbag
components is measured at all times.
Any fault in this system would be
detected immediately by a current fluc-
tuation that would necessarily accom-
pany it. The fault would be indicated
immediately by the airbag warning
lamp.
Even after you shut off the engine, the
overall functional status of your vehicle
is monitored. For example, all of the
flaps of the heating and ventilation
system travel to the nearest limit posi-
tion. This ensures that the defrost func-
tion is always available even if a
malfunction in the air conditioner
system/automatic climate control
should occur while the vehicle is
parked overnight, for instance.
A calibration cycle runs every tenth time
the engine is shut off. During this cycle,
the actuator motors of all the heating
and ventilation flaps travel to their limit
stops in both directions. The limit posi-
tions and the return travel paths are
checked in this manner in order to
ensure that appropriate adjustments for
the operating elements can be made at
any time.You will hear the sounds of the air flaps
as the air conditioning system/auto-
matic climate control carry out their
self-diagnostic functions after the igni-
tion has been turned off. All of the other
self-diagnostics functions operate
silently in the background.
Any possible faults detected during
these self-diagnostics can be read out
by your BMW center during the next
regularly-scheduled maintenance and
corrected with a minimum of time.
