Indicator and warning lamps

Technology that monitors itself

Indicator and warning lamps that are
identified by

●

are tested for proper
functioning whenever the ignition key is
turned. They each light up once for dif-
ferent 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

●

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 seri-
ous engine damage. If the drive belt is
defective, increased steering effort is
also required.

<

Engine oil pressure

●

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 cen-
ter.
Do not continue driving, as the
engine could sustain serious dam-
age from inadequate lubrication.

<

Brake warning lamp

●

If the lamp comes on when the
parking brake is not engaged:
check the brake fluid level. Before driv-
ing further, be sure to comply with the
instructions on pages 116 and 129.
Parking brake warning lamp for
Canadian models.
Tire Pressure Monitor (TPM)/Flat
Tire Monitor

●

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 85, 86

Red and yellow: continue driving
cautiously

The brake warning lamp comes
on together with the yellow indi-
cator lamps for ABS

●
and
ASC+T/DSC:
The entire ABS, CBC,
ASC+T/DSC and
ADB/ADB-X/DBC control sys-
tem has failed. Continue driving
cautiously and defensively. Avoid full
brake applications. Please have the
system checked by your BMW center
as soon as possible.

brake is engaged – an additional
acoustic signal sounds when starting
off. For additional information: refer to

brake warning lamp

●

The indicator lamps remain on:
The ASC+T/ADB or DSC/DTC
have been switched off manually or
there is a system malfunction.
Please consult the nearest BMW cen-
ter.

Dynamic Brake Control (DBC)

●

Malfunction in DBC system.
Conventional braking efficiency
is available and unrestricted.
Have the system repaired at your BMW
center as soon as possible.

models.
Add washer fluid
The washer fluid level is too low.
Top off the fluid at the earliest
opportunity.
For additional information: refer to
page 126
CHECK FILLER CAP

●

This indicator lamp comes on
when the fuel filler cap is loose
or missing.
Close the filler cap tightly: refer to
page 24
SERVICE ENGINE SOON

●

If the indicator lamp comes on
either continuously or intermit-
tently, this indicates a fault in the emis-
sions-related electronic systems.
Although the vehicle remains opera-
tional, you should have the systems
checked by your BMW center at the
earliest possible opportunity.

page 132
SERVICE ENGINE SOON

models.

Engine electronics

●

There is a fault in the electronic
engine-management system.
You can continue to drive with reduced
engine output or engine speed. Please
have the system inspected at your
BMW center.
Add coolant
The coolant level is too low. Add
coolant at the earliest opportu-
nity.
For additional information: refer to
page 128

Green: for your information

Turn signal indicator
Flashes when the turn signals
are on.
Rapid flashing indicates a system mal-
function.

Lights up when the cruise con-
trol is activated: ready for oper-
ation via the steering wheel with multi-
function buttons.

Brake systemBrake fluid levelIf the brake fluid level is too low and
brake pedal travel has become longer,
there may be a defect in one of the two
brake system's hydraulic circuits.
Proceed to the nearest BMW cen-
ter. 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 accord-
ingly.<Disc brakesLimited vehicle use, extended periods
with the vehicle parked or in storage,
and operating conditions in which brak-
ing is restricted to gentle, low-pressure
applications will all increase the ten-
dency for corrosion to form on the
rotors; this is often accompanied by a
simultaneous accumulation of contami-
nation 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 useful 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 undi-
minished 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 71.
Do not coast with the clutch
depressed or with the transmis-
sion or selector lever 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: always refer all brake
inspection and service work to your
BMW center, as failure to observe the
special procedures could result in dam-
age to components of the all-wheel
drive.
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 BMW has
released for your particular vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suitable for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<

Comply with the applicable envi-
ronmental laws regulating the dis-
posal of antifreeze agents with corro-
sion inhibitor.<
Brake fluidIndicator lamp
The brake warning lamp comes
on when the parking brake is
not engaged: the brake fluid
level is too low, refer to page 18.
Parking brake warning lamp for
Canadian models.
Adding brake fluidFor adding brake fluid or for determin-
ing 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
brake pedal travel. Refer to the informa-
tion on page 116.
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 by a
BMW center. Refer to the Service and
Warranty Information Booklet for US
models or the Warranty and Service
Guide Booklet for Canadian models.
Brake fluid is toxic and damages the
vehicle's paint. You should always store
them in their original containers and in a
location which is out of reach of chil-
dren.
Do not spill the brake 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.<
