Indicator and warning lamps

Technology that monitors itself

Many of the systems of your BMW
monitor themselves automatically, both
during engine starts and while you are
driving. Indicator and warning lamps
that are identified by "

●

" are tested for

proper functioning whenever the igni-
tion key is turned. They each light up
once for different periods of time.

If a fault should occur in one of these
systems, the corresponding lamp does
not go out after the engine is started, or
it lights up while the vehicle is moving.
You will see how to react to this below.

Red: stop immediately

Battery charge

●

The battery is no longer being
charged. There is a malfunction

of the alternator V-belt or in the
charging circuit of the alternator. Please
contact the nearest BMW center.

If the V-belt is defective, do not
continue driving. If you do so, the

engine could be damaged due to over-
heating. If the V-belt is defective,
increased steering effort is also
required.

Engine oil pressure

●

Stop the vehicle and switch off
the engine immediately. Check

the engine oil and top off as required. If
the oil level is correct, please contact
the nearest BMW center.

Do not continue driving. If you do
so, the engine could be damaged

because of inadequate lubrication.

Tire Pressure Control (RDC)

●

In addition, an acoustic signal is
sounded: a tire failure has

occurred. Reduce vehicle speed imme-
diately and stop the vehicle. Avoid hard
brake applications. Do not oversteer.
