Indicator and warning lampsYellow: check as soon as possible
Antilock Brake System (ABS) l
ABS has been deactivated in
response to system malfunction.
Conventional braking efficiency is avail-
able without limitations. Please have
the system inspected by your BMW
center.
For additional information, refer to
page 119.
ABS warning lamp for Canadian
models.
Engine oil level
Comes on while driving: the oil
level is at the absolute
minimum; therefore, add engine oil as
soon as possible. Do not drive more
than 30 miles (50 km) until you do.
For additional information, refer to
page 139.
Engine oil level
Comes on after the engine has
been shut off: Add more engine
oil the next time you stop for gas.
For additional information, refer to
page 139.
Brake pads l

Have the brake pads checked.
For additional information, refer
to page 121.
Tire Pressure Control (RDC) l
Check the tire inflation pressure.
Refer to pages 28 and 86.
Automatic Stability Control plus
Traction (ASC+T)/Dynamic
Stability Control (DSC) l
Indicator lamp flashes:
The system is active and governs drive
force and braking force.
The indicator lamp stays lit:
ASC+T has been switched off via the
button, or it is defective, or, the DSC
has been turned off, ADB is in ready
mode.
Please consult the nearest BMW center
in the event of a system malfunction.
For additional information, refer to
ASC+T beginning on page 80.
BMW 325xi, 330xi:
The DSC has either been turned off or
is defective. ADB-X is in ready mode. If
the warning lamp does not go out after
pressing the DSC button repeatedly,
then both the DSC
and ADB-X are
defective.
Please consult the nearest BMW
center.
For additional information, refer to
page 84.
Automatic Stability Control plus
Traction (ASC+T)/Dynamic
Stability Control (DSC) and
brake warning lamp l
The indicator lamps remain on:
The DSC and ADB/DBC have
been switched off by means of the
button or are defective.
Please consult the nearest BMW
center.
For additional information, refer to
page 82.
BMW 325xi, 330xi:
DSC and ADB-X are defective. ADB-X
cannot be switched off.
Please consult the nearest BMW
center.

To ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you comply
with the following recommendations.
Engine and differentialUp to 1,200 miles (2,000 km):
Drive at varying engine speeds and
road speeds, but do not exceed
4,500 RPM or a road speed of 100 mph
(160 km/h) during this initial period.
Obey your local and state maximum
speed limits.
Do not apply full throttle and avoid
pressing the accelerator beyond the
kickdown point.
After 1,200 miles (2,000 km), you can
gradually increase the engine speed or
road speed.
Follow the same break-in procedure if
either the engine or the differential is
replaced in the future.
TiresDue to technical factors associated
with their manufacture, tires do not
achieve their full traction potential until
an initial break-in period has elapsed.
For this reason, drive cautiously during
the first 200 miles (300 km).
Obey your local and state maximum
speed limits.
When the vehicle is operated on
wet or slushy roads, a wedge of
water may form between the tire and
the road surface. This phenomenon is
referred to as aquaplaning, or hydro-
planing, and can lead to partial or
complete loss of traction, vehicle
control and braking effectiveness.
Reduce your speed on wet roads.<
Brake systemBrake pads and disks do not attain their
optimal wear patterns until after approx.
300 miles (500 km).
To break-in the separate parking brake
drums, apply the parking brake lightly
when coasting to a standstill (at a traffic
signal, for instance), provided that
traffic conditions allow you to do so.
To avoid corrosion, repeat this proce-
dure from time to time.
The brake lamps do not come on
when the parking brake is set.
Vacuum for the brake system servo unit
on your BMW is available only when the
engine is running. When you move the
vehicle with the engine off Ð when
towing, for example Ð substantially
higher levels of pedal force will be
required to brake the vehicle. optimally after about 300 miles
(500 km). Engage the gears carefully
during the break-in period.
Break-in procedures

120n
Disc brakesDisc 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 oper-
ating conditions where brake applica-
tions are less frequent, there is an
increased tendency for corrosion of the
discs 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
discs by brake applications is not
reached.
If the brake discs are corroded, they will
tend to respond to braking with a
pulsating effect that even extended
brake applications will fail to cure.
For your own safety: use only
brake pads that BMW has
approved for your particular 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 if they are installed.<
Driving notesWhen driving in wet conditions and in
heavy rain, it is effective to apply light
pressure to the brakes every few miles
or kilometers. Be aware of traffic condi-
tions to ensure that this maneuver does
not endanger other road users. The
heat that is generated by the brake
applications helps to dry the brake
pads and discs.
Maximum braking force is obtained
while the wheels are not locked, but
rather when they are still barely turning
immediately prior to locking. ABS main-
tains this state automatically. If the ABS
fails, you should revert to the staggered
braking technique described on
page 122.
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.
The braking effect of the engine can be
further increased by downshifting, into
first gear, if necessary. In the manual
mode of the automatic transmission,
you can also downshift into first gear.
Refer to page 66.Should engine braking prove inade-
quate, you should still avoid extended,
continuous braking. Instead of main-
taining 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), releasing the pedal,
and then repeating the application
(staggered braking). The cooling
phases between active braking inter-
vals prevent the brakes from over-
heating, thus ensuring that full braking
capacity remains available at all times.
Do not coast with the clutch
depressed or with the shift lever
or selector lever in neutral. Do not drive
with the engine shut off. The engine
provides no braking effect when the
clutch is depressed or the transmission
is in neutral, and there is no power-
assist for braking or steering when the
engine is not running.
BMW 325xi, 330xi: have brake inspec-
tions performed at a BMW center only.
If you do not, parts of the four-wheel
drive system could be damaged.
Do not allow floor mats, carpets or any
other objects to protrude into the area
around the brake pedal, the clutch or
the accelerator which could obstruct
their freedom of movement.<

Brake systemBrake fluid level
If the brake warning lamp
comes on and the parking brake
has been released:
The brake fluid level is too low in the
reservoir (refer to page 143).
If the brake fluid level is too low and
brake pedal travel has become notice-
ably longer, there may be a defect in
one of the hydraulic circuits of the brake
system.
Brake warning lamp for Cana-
dian models.
Proceed to the nearest BMW
center. Higher brake application
pressure may be necessary under these
conditions, and brake pedal travel may
be significantly longer. Please
remember to adapt your driving style
accordingly.<
Brake pads
If the warning lamp for the brake
pads lights up:
The brake pads have reached
their minimum pad thickness. Proceed
to the nearest BMW center as soon as
possible to have the pads replaced.
For your own safety: use only
brake pads that BMW has
approved for your particular 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 if they are installed.<
