Indicator and warning lamps

Technology that monitors itself

Indicator and warning lamps that are
identified by "

l

" are tested for proper
functioning 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 in the
following section.

Red: stop immediately

Battery charge current

l

The battery is no longer being
charged. The alternator drive
belt is defective or there is a malfunc-
tion in the charging circuit of the alter-
nator. Please contact the nearest BMW
center.
If the drive belt is defective, stop
and switch off the engine immedi-
ately to prevent overheating and
serious engine damage. If the drive 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 and top off as
required. If the oil level is correct,
please contact the nearest BMW
center.
Do not continue driving, as the
engine could sustain serious
damage from inadequate lubrication.

Brake hydraulic system

l

The brake fluid level is too low.
Before driving further, be sure to
read the notes on pages 104 and 126.

0 Steering lockedThis is the only position in which the
ignition key can be inserted and
removed.
An acoustic warning sounds when you
fail to remove the ignition key after
opening the driver's door.
After removing the key, turn the
steering wheel slightly to the left or right
until the lock engages.367de009
Vehicles with automatic transmis-
sion
*:
Your vehicle is equipped with an inter-
lock. This means that the ignition key
cannot be turned to position 0 and
removed until the selector lever is in
position "P".
Furthermore, the selector lever is
locked in position "P" when the ignition
key is in position 0 or removed from the
ignition lock.
To turn the key back to position 0 or to
remove it, first move the selector lever
to position "P".<
1 Steering unlockedYou will often find that it is easier to turn
the ignition key from position 0 to 1 if
you move the steering wheel slightly to
help disengage the detent.
Individual electrical equipment and
accessories are available for use.2 Ignition onAll electrical equipment and accesso-
ries are available for use.3 Starting the engineVehicles with manual transmission:
When starting, depress the clutch,
since a lock otherwise prevents the
engine from being started.

With the switch in this position,
vehicle lighting on both sides is
on.

When you switch the ignition off
while the low beams are still on,
only the parking lamps (position lamps/
side marker lamps) remain on.

intensity, turn the pulled switch. 367us021
LIGHTS ON warningWhen you open the driver's door after
turning the ignition key to position 0,
a warning signal sounds for a few
seconds to remind you if the headlamps
have not been switched off.Daytime driving lamps
*
The headlamps are automatically
switched on for daylight driving at
ignition key position 2.
Front fog lamps
*
A green indicator lamp comes
on in the instrument cluster to
indicate that the front fog lamps
are on.
It is not possible to switch on the front
fog lamps together with the high
beams.

ABS Disc brakesDynamic Brake Control (DBC)*DBC is included in the DSC, refer to
information beginning on page 74.
If you step on the brake rapidly, this
system automatically produces
maximum braking force boost and thus
helps to achieve the shortest possible
braking distance during "panic stops".
All of the benefits of the ABS system
are exploited under these circum-
stances.
Do not reduce the pressure on the
brake pedal for the duration of the
brake application. When the brake
pedal is released, the DBC is deacti-
vated.
In the event of a malfunction,
the brake warning lamp lights up
yellow. Normal braking effi-
ciency is still fully available.
Have the system checked and
repaired at your BMW center as
soon as possible.
Please observe the section "Infor-
mation for your safety" concerning
the ABS system, which also applies to
the DSC system.<
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, or in oper-
ating conditions where brake applica-
tions are less frequent, there is an
increased tendency for corrosion of the
rotors 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 rotors 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
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 in the event of their use.<
Driving notesWhile driving in wet conditions and in
heavy rain, it is advisable to apply light
pressure to the brake pedal every few
miles Ð watch traffic conditions to
ensure that this maneuver does not
endanger other road users. The heat
generated in this process helps dry the
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
described on page 106.
Extended or steep mountain descents
should be driven in the gear in which
only minimal periodic brake application
is required. This avoids excessive strain
on the brakes and possible
impairment of the braking effect.
You can increase the engine's braking
effect by selecting progressively lower
gears, downshifting into first gear, if
necessary. You can also downshift into
first gear if you are using the manual
mode in a vehicle with automatic trans-
mission, refer to page 63.

Coolant Brake fluid To add coolantWait until the engine cools before
removing the cap from the expansion
tank. The needle of the coolant gauge
in the instrument cluster must be
located in the blue field; otherwise,
there is a danger of scalding.
1. Turn the cap slightly counterclock-
wise in order to allow accumulated
pressure to escape, then open
2. If the coolant is low, slowly add
coolant until the correct level is
reached Ð do not overfill.
The coolant is a mixture of water and
extended-duty antifreeze with corrosion
inhibitor. Always maintain the
prescribed all-season 50 : 50 mixture
ratio for year-round protection against
internal corrosion. No other additives
are required.
Replace the coolant regularly. Refer to
the Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide Booklet (Canadian
models).If the warning lamp for the brake
hydraulic system comes on:
The brake fluid level is too low, refer
also to the instructions on page 104.
For adding brake fluid or for deter-
mining and correcting the cause of
brake fluid loss, consult your BMW
center. Your BMW center is familiar
with the specifications for factory-
approved brake fluids (DOT 4).

Brake fluid loss may result in extended
brake pedal travel. If this occurs, refer
to the notes on page 104.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the operating safety
and reliability of the brake system, have
the brake fluid changed every two years
by a BMW center, refer also to the
Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide Booklet (Canadian
models).367de740

Any BMW center will be happy to
advise you concerning the advisability,
legal implications and factory recom-
mendations for technical modifications
to the vehicle. For this purpose, the
BMW center will require the Vehicle
Identification Number. The engine
number is also required in some
instances.
Light-emitting diodes (LEDs)Light-emitting diodes installed behind
translucent lenses serve as the light
source for many of the controls and
displays in your vehicle. These LEDs
are similar to conventional laser tech-
nology.
Do not remove the protective lens
and avoid staring directly at the
unfiltered beam for extended periods
(several hours), since inflammation of
the iris could result.<
California laws require us to state the
following warning:
Engine exhaust, some of its
constituents, and certain vehicle
components contain or emit chemicals
known to the State of California to
cause cancer and birth defects or other
reproductive harm.<
