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 122 and 135.
Brake warning lamp for Cana-
dian models.
Flat Tire Monitor
●
In addition, an acoustic signal is
sounded: there is a flat tire.
Reduce speed and carefully come to a
stop. Avoid sudden braking and steer-
ing maneuvers.
For additional information: refer to
page 91
Red and yellow: continue driving
cautiously
The brake warning lamp comes
on together with the yellow indi-
cator lamps for ABS
●
and
DSC:
The entire ABS, CBC, DSC and
ADB-X/DBC control system has
failed. Continue driving cau-
tiously and defensively. Avoid
full brake applications. Please have the
system checked by your BMW center
as soon as possible.

ing lamps for Canadian models.
Red: an important reminder
Brake warning lamp

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

Dynamic Stability Control (DSC)
and brake warning lamp
●
The indicator lamps remain on:
DSC/DTC have been switched
off with the button or are faulty.
Please consult the nearest BMW
center.
Additional information beginning on
page 86
325xi:
DSC and ADB-X system malfunction.
There is no provision for switching off
ADB-X.
Please consult the nearest BMW cen-
ter.

ing lamps for Canadian models.
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.

Add washer fluid
The washer fluid level is too low.
Top off the fluid at the earliest
opportunity.
For additional information: refer to
page 132
CHECK GAS CAP*
●
This indicator lamp comes on
when the gas cap is loose or
missing.
Close the gas 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.
For additional information: refer to
page 138
Service Engine Soon
indicator lamp for Canadian
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.

page 134
Green: for your information

Brake systemBrake fluid levelLow brake fluid level in the reservoir
combined with longer than usual pedal
travel may indicate a defect in one of
the 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.
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
rotors and accumulation of contamina-
tion on the brake pads. This occurs
because the minimal pressure that must
be exerted by the pads to clean the
rotors by brake applications is not
reached.
Corrosion on brake rotors is signaled by
a running or pulsation during braking;
even extended subsequent braking will
not cure this phenomenon.
It is a good idea to periodically dry the
brakes with a gentle application when
driving in rain and on wet roads. 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
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.
This helps avoid placing excessive
loads on the brake system. Use care to
avoid exceeding the approved engine-
speed range, refer to page 79.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.
325xi: always refer all brake inspection
and service work to your BMW center,
as failure to observe the special proce-
dures could result in damage to com-
ponents 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 which BMW has
approved for your specific 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.<

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.
Brake warning lamp for Cana-
dian 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 122.
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
it in its closed original container 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.<
