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 charg-
ing 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 re-
quired. If the oil level is correct: please
contact the nearest BMW center.
Do not continue driving. The en-
gine could be damaged because
of inadequate lubrication.

Comes on when you engage the
parking brake.
For additional information: refer to
page 65.
Comes on although the parking brake
is released: have the brake fluid level
checked. Before continuing your jour-
ney, be sure to read the notes on
pages 123 and 141.
Also comes on in the Check Control
with the message "CHECK BRAKE

Coolant temperature gauge Service Interval Display Blue The engine is still cold. Drive at moder-
ate engine and vehicle speeds. Red When you switch on the ignition, the
warning lamp comes on briefly to con-
firm that the system is operational.
Comes on while driving and the mes-
sage "COOLANT TEMPERATURE" ap-
pears in the Check-Control
*: the engine
is overheated. Shut off the engine im-
mediately and allow it to cool down.

Between the blue and red zones Normal operating range. It is not un-
usual 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 140.
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. Red lamp The maintenance deadline has been
passed. 390us008

Check 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 ap-
prox. 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 vi-
sual indicator for:
>LIGHTS ON and
>KEY IN IGNITION LOCK. 390de121
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 76
and 140.
>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 op-
erating conditions where brake applica-
tions are less frequent, there is an in-
creased tendency for corrosion of the
rotors and accumulation of contamina-
tion on the brake pads. This occurs be-
cause the minimal pressure which must
be exerted by the pads to clean the ro-
tors by brake applications is not
reached.
If the brake rotors 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 re-
leased for your particular vehicle
model. BMW cannot evaluate non-ap-
proved brake pads to determine if they
are suited for use, and therefore cannot
ensure the operating safety of the vehi-
cle 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 rotors.
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 124).
Extended or steep mountain descents
do not necessarily have to lead to re-
duced braking efficiency. Move the se-
lector lever to the appropriate lower
range in which only minimal periodic
brake applications are required.
You can increase the engine's braking
effect by selecting progressively lower
gears, downshifting as far as 1st gear,
on steep descents. If engine braking should prove to be in-
adequate, you should still avoid ex-
tended, continuous braking. Instead of
maintaining low to moderate pressure
over an extended period of time, you
should decelerate by applying more
substantial pressure to the brake pedal
(watch for following traffic), then releas-
ing the pedal, then repeating the appli-
cation. This staggered braking tech-
nique allows the brakes to cool in the
intervals between active braking
phases, preventing overheating and en-
suring that full braking capacity remains
available at all times.
Do not coast with the selector le-
ver in ÒNeutralÒ. Do not drive with
the engine shut off. The engine pro-
vides no braking effect when the trans-
mission is in ÒNeutralÒ, and there is no
power-assist for braking or steering
when the engine is not running.
Have brake inspections performed at
an authorized 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 accelerator and brake ped-
als and obstruct their movement.<
