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.

Fuel gauge Coolant temperature gauge Once the indicator lamp stays on
continuously, there are still approx.
2 gallons (8 liters) of fuel in the fuel
tank.
For fuel tank capacity, refer to
page 181.
If the tilt of the vehicle varies (extended
driving in mountainous areas, for
example), there may be slight fluctua-
tions of the needle.
Fill the fuel tank well before it is
empty. Driving to the last drop of
fuel can result in damage to the engine
and/or the catalytic converter.<
When the ignition is switched on, the
indicator lamp in the fuel display will
light up briefly to confirm that the
system is operational.
BlueThe engine is still cold. Drive at
moderate engine and vehicle speeds. RedTo confirm that the system is opera-
tional, the warning lamp in the coolant
temperature gauge will light up briefly
when the ignition is switched on.
If the lamp comes on while operating
the vehicle: the engine is overheated.
Stop and switch the engine off immedi-
ately and allow it to cool down.
Checking coolant level, refer to
page 129.
Between the blue and red zonesNormal operating range. It is not
unusual for the needle to rise as far as
the edge of the red zone in response to
high outside temperatures or severe
operating conditions.

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.

82n
Tire Pressure Warning (RDW)Activating/deactivating the
systemThe system is automatically active in
ignition key position 2 and is therefore
always on during driving.
To deactivate the system: tap the
button, the indicator lamp will light up
yellow.
To activate the system: tap the button
again; the indicator lamp goes out.
Deactivate the system while driving
with snow chains, since false warnings
and undetected losses in pressure are
possible under these kinds of condi-
tions.
In the event of a flat tire
The indicator lamp on the instru-
ment cluster will light up red in
the event of a significant loss in
tire pressure. In addition, an acoustic
signal is sounded. To come to an imme-
diate stop, reduce speed, while
avoiding any sudden, jerky braking or
steering maneuvers.
Fix the flat tire using the M Mobility
system (refer to page 153).
Resetting the indicator lamp: the red
indicator lamp has to be turned off
manually after putting on a new wheel.
At this point, hold the RDW button
down until the indicator lamp goes out.
Re-initialize the system afterward.
The RDW cannot alert you to
severe and sudden tire damage
caused by external factors.
The RDW will not identify the natural,
even loss of pressure in all four tires,
either.<
Check the tire inflation pressure
on a regular basis and correct if
necessary. Refer to page 27.
Under certain circumstances, there
may be false warnings or a delayed
detection of losses in pressure when
driving on snow-covered or slippery
road surfaces.
A sporty driving style (slip at the wheels
receiving the torque, high lateral accel-
erations) can lead to delayed RDW
warnings.<
System malfunctionAs long as there is still a malfunction,
the indicator lamp on the instrument
cluster will remain yellow.
Please contact your BMW center for
additional information.

Parking lamps/Side marker lamps
With the switch in this position,
vehicle lighting is illuminated on
both sides. You can use the side
lamps for parking. Refer to page 85 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 turn the headlamp flasher
on after you have parked the vehicle,
the low beam headlamps will remain on
for a short period of time. You can also
have this function deactivated.<
"LAMPS 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.Daylight driving 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.
In order to spare the battery, all of
the lamps in the vehicle are
switched off automatically approx.
15 minutes after the ignition key has
been turned to position 0.<
Turn the rotary dial to control the
lighting when the side lamps or low
beam headlamps are on.
