Indicator and warning lamps

Technology that monitors itself

The system runs a check on the
warning and indicator lamps marked
by "

l

" each time you switch on the
ignition. They each light up once for dif-
ferent 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.
The following section describes how
you should respond.

Red: stop immediately

Battery charge current

l

The battery is no longer being
charged. This indicates a defect
in the alternator drive belt or in the
charging circuit of the alternator. Please
contact the nearest BMW center.
You should never attempt to con-
tinue driving with a defective drive
belt, as the engine could overheat and
sustain serious damage. If the drive belt
is defective, increased steering effort is
also required.

Engine oilChecking oil level1. Park the vehicle on a level surface
2. Switch the engine off after it has
reached normal operating tempera-
ture
3. After approx. 5 minutes, pull the dip-
stick out and wipe it off with a clean
lint-free cloth, paper towel, or similar
material
4. Carefully push the dipstick all the
way into the guide tube and pull it
out again
5. The oil level should be in between
the two marks on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions.390de647
The oil volume between the two marks
on the dipstick corresponds to approx.
1.1 US quarts (1 liter). Do not fill beyond
the upper mark on the dipstick. Excess
oil will damage the engine.460de189
Adding engine oilWhile you should wait until the level has
dropped to just above the lower mark
before adding oil, you should never
allow the oil level to fall below this
mark.
BMW engines are designed to
operate without oil additives; the
use of additives could lead to damage
in some cases. This is also true for the
manual transmission, the automatic
transmission, the differential, and the
power steering system.<
Recommendation: have the oil changed
by your BMW center only.390de626
