Indicator and warning
lamps
Technology that monitors itself
Indicator and warning lamps that are iden-
tified by
+ are tested for proper functioning
whenever the ignition key is turned. They
each light up once for different periods of
time.
If a fault should occur in one of these sys-
tems, the corresponding lamp does not go
out after the engine is started or it lights up
again while the vehicle is moving. The indi-
cated pages provide information on what
measures to take.

>Forceful braking and braking with ABS:
Brake lamps 1 and 2 light up on both
vehicle sides together with the center
brake lamp.
Antilock Brake System ABS
The concept
ABS keeps the wheels from locking during
braking, thereby enhancing active driving
safety.
Malfunction
If the yellow indicator lamps for the
Antilock Brake System ABS come
on together with the brake warning
lamp and the indicator lamp for the
Dynamic Stability Control DSC:
The entire ABS and DSC control
system has failed. Continue driving
cautiously and defensively. Avoid
hard brake applications. Please have the
system checked by your BMW center as
soon as possible.
ABS and DSC indicator and warn-
ing lamps for Canadian models.
Braking with ABS
If you are in a situation which requires full
braking, you will exploit the full benefits of
the ABS system if you apply maximum
brake pressure – panic stop.
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.
Flat Tire Monitor
The concept
The tire pressure is determined using the
signals of the ABS sensors.
The system provides an alert whenever the
tire pressure of one tire drops relative to
that of another.
Prerequisites
In order for the system to "learn" the cor-
rect tire inflation pressures, please do the
following:
>Check the inflation pressure in all tires
>Compare to the inflation pressure table
– refer to page 72 – and correct if nec-
essary
>Initialize the system.
Check the tire pressures regularly
and correct if necessary. Refer to
page 71.<
Indicator lamp
In the event of a flat tire
The indicator lamp lights up red; in
addition, an acoustic signal is
sounded:
Respond immediately by carefully reducing
vehicle speed to under 50 mph / 80 km/h.
Avoid hard brake applications and steering
maneuvers.
If your vehicle is equipped with
Run Flat tires, note the information on
page 75.<
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 recog-
nize is the even and very gradual pressure
loss that takes place in all tires over an
extended period of time.<
