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 "
 
l
 
" 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.

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

Stop the vehicle immediately 
and switch off the engine. 
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.

In addition, an acoustic signal is 
sounded: a tire failure has 
occurred. Reduce vehicle speed imme-
diately to stop the vehicle. Avoid hard 
brake applications. Do not oversteer.
