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.
 
Red: Stop immediately
 
Battery charge 
 
l
 
 
The battery is no longer being 
charged. There is a malfunction 
of the alternator ribbed V-belt or in the 
charging circuit of the alternator. Please 
contact the nearest BMW center.
If the ribbed V-belt is defective, do 
not continue driving. If you do so, 
the engine could be damaged due to 
overheating. If the ribbed V-belt is de-
fective, increased steering effort is also 
required.<
Engine oil pressure l 
Stop the vehicle and switch off 
the engine immediately. Check 
the engine oil and top up 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 oc-
curred. Reduce vehicle speed immedi-
ately and stop the vehicle. Avoid hard 
brake applications. Do not oversteer.
