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 current

l

The battery is no longer being
charged. There is a malfunction
of the alternator drive belt or in the
charging circuit of the alternator. Please
contact the nearest BMW center.
If the drive belt is defective, do not
continue driving. The engine could
be damaged due to overheating. If the
V-belt is defective, increased steering
effort is also required.

<


Engine oil pressure

l

Stop vehicle immediately and
switch off engine. Check the
engine oil level and top up as required.
If the oil level is correct: please contact
the nearest BMW center.
Do not continue driving, other-
wise, the engine could be
damaged because of inadequate lubri-
cation.

<



Tire Pressure Warning (RDW)
In addition, an acoustic signal is
sounded: a flat tire has
occurred. To come to an immediate
stop, reduce speed, while avoiding any
sudden, jerky braking or steering
maneuvers.
For additional information, refer to
page 78.
Brake hydraulic system

l

If the lamp comes on when the
parking brake is not engaged:
Check the brake fluid level. Before
driving further, be sure to read the addi-
tional information on pages 107
and 126.

BMW center.
For additional information,refer to
pages 56, 158.

Red and yellow: continue driving
cautiously
If the 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.
For additional information, refer to
pages 76, 105.
ABS, CBC and DSC indicator
and warning lamps for Canadian
models.
Yellow: check as soon as possible
Antilock Brake System (ABS) l
ABS has been deactivated in
response to system malfunction.
Conventional braking efficiency is avail-
able and unrestricted. Please have the
system inspected by your BMW center.
For additional information, refer to
page 104.
ABS warning lamp for Canadian
models.
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 30 miles (50 km) until you do.
For additional information, refer to
page 123.
Engine oil level
Comes on after the engine has
been shut off: add more engine
oil the next time you stop for gas.
For additional information, refer to
page 123.
Brake pads l
Have the brake pads checked.
For additional information, refer
to page 107.

Indicator and warning lamps
Tire Pressure Warning (RDW) l
RDW has been switched off or
has been deactivated because
of a malfunction. In the event of a
malfunction, have the system checked
by your BMW center.
For additional information, refer to
pages 26, 78.
Dynamic Stability Control
(DSC) l
The indicator lamp flashes when
the system is active and governs drive
force and braking force.
If the indicator lamp fails to go out after
the engine is started, or if it comes on
during normal driving and stays on:
DSC has been switched off via the
button or because of a malfunction.
In the event of a malfunction, have the
system checked by the nearest BMW
center.
For additional information, refer to
page 76 and on.
Add washer fluid
The washer fluid is too low.
Top up the fluid at the earliest
opportunity.
For additional information, refer to
page 122.
Service Engine Soon l
If the indicator lamp comes on
either continuously or intermit-
tently, this indicates a fault in the emis-
sions-related electronic systems.
Although the vehicle remains opera-
tional, you should have the systems
checked by your BMW center at the
earliest possible opportunity.
For additional information, refer to
page 135.
Warning lamp: Service Engine
Soon for Canadian models.
Engine electronics l
There is a fault in the engine's
electronic control system. The
electronics allow for continued driving
with reduced engine output or speed.
Please have the system inspected by
your BMW center.
Add coolant
The coolant level is too low.
Add coolant at the earliest
opportunity.
For additional information, refer to
page 125.
Green: for your information

Tire Pressure Warning (RDW)The conceptThe Tire Pressure Warning (RDW) moni-
tors the tire pressure in all four wheels
while driving. The system detects
whenever the inflation pressure in a tire
drops significantly.
Controlling the tire pressure is based
on monitoring the speed of the tires
relative to each other. A flat tire is
detected and reported because the
speed suddenly deviate drastically from
one another.
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 27),
and adjusting their pressure if neces-
sary
2 Turn the ignition key to position 2
3 Continue to press the button until the
yellow indicator lamp in the instru-
ment cluster lights up. After a short
time, the indicator lamp will go out
automatically
4 After a few minutes, the RDW will
accept the current inflation pressure
as the value to be measured against,
and from that point on, can detect
and report a flat tire.

Side lamps
With the switch in this position,
the front, rear and side vehicle
lighting comes on. You can use
the side marker lamps for parking.
Refer to page 82 for one-sided lighting
as an additional possibility for parking.
Low beam headlamps
When you switch the ignition off
with the low beam headlamps
on, only the side lamps will
remain on.
"Follow-Me-Home" lamps:
If you activate the headlamp
flasher after you have parked the
vehicle, the low beam lamps will remain
on for a short period of time. You may
also have this function deactivated if
you wish.<
"LIGHTS ON" warningWhenever you open the driver's door,
after having turned the ignition key to
position 0, you will hear a buzzing
sound for a few seconds to remind you
that the lamps have not been switched
off.Daytime running lamps
*
If you desire, the lamp switch can be
left in the second position. When the
ignition is switched off, the external
lighting is also switched off.
Turn the rotary dial to control the
lighting when the side or low beam
lamps are on.

Brake system Brake fluid level
If the brake warning lamp
comes on with the parking
brake released:
The brake fluid level is too low in the
reservoir (refer to page 126).
If the brake fluid level is too low and
brake pedal travel has become notice-
ably longer, there may be a defect in
one of the brake system's hydraulic
circuits.
Brake warning lamp for Cana-
dian models.
Proceed to the nearest BMW
center. Higher brake application
pressure may be necessary under these
conditions, and brake pedal travel may
be significantly longer. Please
remember to adapt your driving style
accordingly.<
Brake pads
If the warning lamp for the brake
pads lights up: only the
minimum pad thickness still
remains on the brake pads. Proceed to
the nearest BMW center as soon as
possible to have the pads replaced.
For your own safety: use only
brake pads which BMW has
approved for your specific vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<
