Indicator and warning lamps
Technology that monitors itself
The system runs an operational check
on the indicator and warning lamps
identified with the
l
symbol each time
you switch on the ignition. 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 defective
alternator drive belt or a problem with
the alternator's charge circuit. 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; 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 warning lamp
l
If the lamp comes on when the
parking brake is not engaged:
check the brake fluid level. Before
driving further, be sure to comply with
the instructions on pages 106 and 118
Brake warning lamp for Cana-
dian models.
Tire Pressure Monitor (RDC)/
Flat Tire Monitor
l
In addition, an acoustic signal is
sounded: a tire failure has occurred.
Reduce vehicle speed immediately and
stop the vehicle. Avoid hard brake
applications. As you steer the vehicle,
use caution and avoid overcorrecting.
For additional information: refer to
pages 78 and 80

Brake systemBrake fluid level If the brake fluid level is too low and
brake pedal travel has become longer,
there may be a defect in one of the
brake system's hydraulic circuits.
Proceed to the nearest BMW
center. It may be necessary to
apply higher levels of pressure to the
pedal when stopping and braking
distances may also be longer. Please
remember to adapt your driving style
accordingly.
and operating conditions in which
braking is restricted to gentle, low-
pressure applications will all increase
the tendency for corrosion to form on
the rotors; this is often accompanied by
a simultaneous accumulation of
contamination on the brake pads. The
pads must exert a certain minimal level
of pressure against the rotors for the
disc brakes' inherent self-cleaning
effect to remain effective; the pressure
available under the above conditions
may not provide adequate cleansing.
If the brake rotors are corroded, they
will tend to respond to braking with a
pulsating effect that even extended
brake applications will fail to cure.
When driving in heavy rain and on wet
roads it is a good idea to apply light
pressure to the brake pedal every few
miles. Monitor traffic conditions to
ensure that this maneuver does not
pose a hazard to you or to other road
users. The heat generated in this
process helps dry the pads and rotors
to ensure that your brake system will
respond with undiminished efficiency
when you need it.
When descending steep hills and
extended grades, downshift to a gear
that will allow you to continue safely
with only a minimal amount of braking.
By minimizing the loads placed on the
brake system, this strategy helps
ensure that optimal brake system
response will remain available at all
times. Use care to avoid exceeding the
approved engine-speed range, refer to
page 66.Do not coast with the clutch
depressed or with the transmis-
sion in neutral. Do not coast with the
engine shut off. The engine provides no
braking effect when the clutch is
depressed and there is no power-assist
for braking or steering when the engine
is not running.
BMW 325xi, 330xi: always refer all
brake inspection and service work to
your BMW center, as failure to observe
the special procedures could result in
damage to brake system components.
Never allow floor mats, carpets or any
other objects to protrude into the area
around the accelerator, clutch and
brake pedals and obstruct their move-
ment.<
Brake pads
For your own safety: use only
brake pads that the manufacturer
has released for your particular vehicle
model. The manufacturer cannot eval-
uate 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.<

Brake fluidWarning lamp
The brake warning lamp comes
on when the parking brake is
not engaged: the brake fluid
level is too low, refer to page 17.
Brake warning lamp for Cana-
dian models.
Adding brake fluidFor 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 results in extended
pedal travel. Refer to the information on
page 106.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the brake system's
safety and reliability, have the brake
fluid changed every two years at a
BMW center, refer to page 67 and to
the Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide Booklet (Canadian
models).
Brake fluid is toxic and damages the
vehicle's paint. You should always store
it in original container and in a location
which is out of reach of children.
Do not spill the fluid and do not fill the
brake fluid reservoir beyond the MAX
mark. The brake fluid could ignite upon
contact with hot engine parts and
cause serious burns.<
Comply with the applicable envi-
ronmental laws regulating
the disposal of brake fluid.<
