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 V-belt or in the
charging circuit of the alternator. Please
contact the nearest BMW center.
If the V-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 the vehicle immediately
and switch off the engine.
Check the engine oil level; top up as
required. If the oil level is correct:
please contact the nearest BMW
center.
Do not continue driving. The
engine could be damaged
because of inadequate lubrication. <
Parking brake*/
Brake hydraulic system l
Comes on when you engage the
parking brake. For additional informa-
tion: refer to page 66.
Comes on although the parking brake
is released: have the brake fluid level
checked. Before continuing your
journey, be sure to read the notes on
pages 141 and 161.
Also comes on in the Check Control
with the message "CHECK BRAKE
LININGS." Parking brake warning lamp

Blue
The engine is still cold. Drive at
moderate engine and vehicle speeds.
Red
When you switch on the ignition, the
warning lamp comes on briefly to
confirm that the system is operational.
If the warning lamp comes on while
driving or the message "COOLANT
TEMPERATURE" appears in the Check
Control
*: the engine is overheated.
Shut off the engine immediately and
allow it to cool down.

Normal 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.
Checking coolant level: refer to
page 160.
The range of available displays varies
according to your individual vehicle's
equipment.
Green lamps
The number of illuminated lamps
decreases as the time for your next
maintenance visit approaches.
Yellow lamp
This field appears together with
OILSERVICE or INSPECTION.
Maintenance is due. Please contact
your BMW center for an appointment.

The maintenance deadline has been
passed.

Overview
79nCheck Control
Graphic display*
The following alerts or status messages
are displayed with icons from ignition
key position 2 and up until the defects
are corrected:
1 Check low beams
2 Add washer fluid (goes out after
approx. 1 minute)
3 Door open
4 Tailgate open
5 Check brake and tail lamps. A defective center brake lamp is indi-
cated by the upper symbol
When you open the door after stopping,
a warning signal sounds without a
visual indicator for:
> LIGHTS ON and
> KEY IN IGNITION LOCK.

Alphanumeric display*
Text messages are used to alert the
driver to system malfunctions when the
ignition key is turned to position 2. The
alert is accompanied by a gong.
1 Status report symbol
2 Display
3 CHECK button
Messages concerning system faults are
differentiated based on two priorities:
390us111
Priority 1
These defects are immediately indi-
cated by a gong and a flashing warning
symbol 1. Simultaneous defects will be
displayed consecutively. These status
messages remain in the display until the
defects are corrected. They cannot be
deleted by pressing the CHECK
button 3:
> RELEASE PARKINGBRAKE
> COOLANT TEMPERATURE
The coolant is overheated. Stop the
vehicle immediately and switch off
the engine. Refer to pages 78
and 160.
> STOP!ENGINE OILPRESS
The oil pressure is too low. Stop the
vehicle immediately and switch off
the engine. Refer to page 22.

Disc brakes Disc brakes furnish optimum decelera-
tion and braking control and greater
fade resistance under heavy use.
When the vehicle is driven only occa-
sionally, during extended periods when
the vehicle is not used at all, and in
operating conditions where brake appli-
cations are less frequent, there is an
increased tendency for corrosion of the
discs and accumulation of contamina-
tion on the brake pads. This occurs
because the minimal pressure which
must be exerted by the pads to clean
the discs by brake applications is not
reached.
If the brake discs are corroded, they will
tend to respond to braking with a
pulsating effect which even extended
application will fail to cure.
For your own safety: use only
brake pads that BMW has
released for your particular 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.<
Driving notes When driving in wet conditions and in
heavy rain, it is advisable to apply light
pressure to the brake pedal every few
miles (kilometers). Watch traffic condi-
tions to ensure that this maneuver does
not endanger other road users. The
heat which is generated by the brake
applications helps to dry the brake
pads and discs.
Maximum braking force is obtained
while the wheels continue to rotate,
peaking when the wheels remain on the
verge of locking without actually doing
so. ABS maintains this state automati-
cally. If the ABS fails, you should revert
to the staggered braking technique
(refer to page 142).
Extended or steep mountain descents
should be driven in the gear in which
only minimal periodic brake applica-
tions is required. This avoids excessive
strain on the brakes and possible
impairment of the braking effect.
You can further increase the engine's
braking effect by selecting a lower gear,
downshifting as far as first gear.
When driving a vehicle with automatic
transmission, you can still downshift
into first gear. Refer to page 69.If engine braking should prove to be
inadequate, you should still avoid
extended, continuous braking. Instead
of maintaining low to moderate pres-
sure over an extended period of time,
you should decelerate by applying
more substantial pressure to the brake
pedal (watch for following traffic), then
releasing the pedal, then repeating the
application. This staggered braking
technique allows the brakes to cool in
the intervals between active braking
phases, preventing overheating and
ensuring that full braking capacity
remains available at all times.
Do not coast with the clutch
depressed or with the transmis-
sion or selector lever in neutral. Do not
drive with the engine shut off. The
engine provides no braking effect when
the clutch is depressed or the transmis-
sion is in neutral, and there is no
power-assist for braking or steering
when the engine is not running.
Have brake inspections performed at
an BMW center only. If you do not,
parts of the four-wheel drive system
could be damaged. Never allow floor
mats, carpets or any other objects to
protrude into the area around the accel-
erator, clutch and brake pedals and
obstruct their movement.<
