Indicator and warning lamps

Technology
that monitors itself

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

l

" are tested for proper
operation 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
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 current

l

The battery is no longer being
charged. Indicates a problem
with the alternator's drive belt or a
defect in the charging circuit. Please
contact the nearest BMW center.
Never attempt to continue driving
with a defective alternator drive
belt, as this could result in overheating
and serious engine damage. A defec-
tive belt also leads to a substantial
increase in the amount of effort
required to steer the vehicle.

<


Engine oil pressure

l

Stop vehicle immediately and
switch off engine. Check the
engine oil and top up as required. If the
oil level is correct: please contact the
nearest BMW center.
Do not attempt to continue
driving, as lack of adequate lubri-
cation can lead to serious engine
damage.

Tire Pressure Warning (RDW)
This display is accompanied by
an audible warning signal: the
vehicle has a flat tire. Reduce your
speed immediately and avoid all abrupt
braking or steering maneuvers as you
bring the vehicle to a halt.
For additional information, refer to
page 81.
Brake warning lamp l
If the lamp comes on when the
parking brake is not engaged:

Lock backrest/Please fasten
safety belt l
The warning lamp flashes if a
backrest detent is not locked in place,
or comes on continuously if a safety
belt has not (yet) been fastened. The
visual warning is supplemented by an
acoustic signal.
For detailed information on locking the
backrest, refer to page 51.

belts, refer to page 57.
Airbags l
Please respond to any defects
by having the system checked
at your BMW center as soon as
possible.
For additional information, refer to
pages 61, 168.
Red and yellow:
continue driving cautiously
The red brake warning lamp
comes on together with the
yellow indicator lamps for ABS
and DSC:
The entire ABS, CBC 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.

Yellow: check as soon as possible
Antilock Brake System (ABS) l
ABS has been deactivated in
response to a system malfunc-
tion. Conventional braking efficiency is
available without limitations. Please
have the system checked by your BMW
center.

Engine oil level
Lights up while driving:
The oil level is at the absolute
minimum; therefore, add engine oil as
soon as possible. Do not drive more
than approx. 30 miles (50 km) until you
do.
For additional information, refer to
page 127.
Engine oil level
Comes on after the engine has
been shut off: add more engine

Tire Pressure Warning (RDW)The conceptThe Tire Pressure Warning system
(RDW) monitors the tire inflation pres-
sure in all four tires while driving. The
system is designed to detect whenever
the inflation pressure in a tire drops off
significantly.
By monitoring the speeds of the tires
relative to each other, a flat tire can be
detected and reported because its
speed suddenly deviates drastically
from that of the other tires.
Initializing the systemInitializing is necessary to familiarize the
system with the correct inflation pres-
sure.
Repeat this process after any changes
in tire inflation pressure, tire rotation or
replacement. Do not carry out further
system initialization after correcting the
inflation pressure and letting the system
"learn" what condition is required.
1 Check the tire inflation pressure in all
the tires, comparing them with the
inflation pressure table (page 28),
and adjusting their pressure if neces-
sary
2 Turn the ignition key to position 2
3 Press button until the yellow indicator
lamp on the instrument cluster lights
up. After a little while, the indicator
lamp will go out automatically
4 After a few minutes, the RDW will
accept the current inflation pressure
as its reference value, and from that
point on, can detect and report a flat
tire.
