OverviewControlsMaintenanceRepairsDataIndex
Parking brake Manual transmission The parking brake is primarily designed
to prevent the vehicle from rolling while
parked. It operates on the rear wheels.To engageThe detent engages automatically, the
indicator lamp in the instrument cluster
comes on when the ignition key is in
position 2, refer to page 18.To releasePull up slightly on the lever, press the
button (arrow) and lower the lever.
If exceptional circumstances
make it necessary to engage the
parking brake while the vehicle is in
motion, do not pull it with excessive
pressure. Keep your thumb pressed
against the release button while care-
fully pulling the lever up to apply
moderate pressure.
Excessive pressure can lead to over-
braking and loss of traction (fishtailing)
at the rear.
The brake lamps do not come on when
the parking brake is engaged.
Vehicles with manual transmission:
Always engage the parking brake when
parking on hills and slopes, as first gear
or reverse may not provide adequate
resistance to rolling.
Vehicles with automatic transmission:
Place the selector lever in "Park".<
To avoid corrosion and one-sided
braking, apply the parking brake lightly
from time to time when coasting to a
standstill (at a traffic signal, for
instance), provided that it is safe to do
so.
Reverse Select only when the vehicle is
stationary. Press the shift lever to the
left to overcome the slight resistance.
As you do this, the backup lamps will
turn on automatically when the ignition
key is in position 2.
Do not hold the vehicle in place on
slopes by slipping or "riding" the
clutch. Use the parking brake instead.
Riding the clutch leads to severe and
premature clutch wear.<

Automatic transmission with Steptronic
*
You can drive as with a normal auto-
matic transmission. In addition, you can
also shift manually.
When you move the selector lever from
the "D" position to the left into the M/S
range, the performance-oriented shift
programs of the automatic transmission
are engaged. Steptronic enters the
manual selection mode and executes
the desired shift whenever you tap the
selector lever in the direction indicated
by "+" or "Ð". Whenever you want to use
automatic again, just move the selector
lever toward the right to position D.
Range selection
P R N D M/S + Ð
Starting the engineThe engine can only be started in
selector lever positions P ("Park") or N
("Neutral").Range selectionA detent prevents inadvertent shifts to
the "Reverse" or "Park" selector lever
positions. To disengage the detent,
press the button on the front side of
the selector lever button (arrow).
While the vehicle is stationary and
before shifting out of "Park" or
"Neutral", depress the footbrake in
order to disengage the selector lever's
lock mechanism (Shiftlock).
Hold the footbrake down until starting
off. The vehicle will otherwise "creep"
when a drive position is engaged.<
To prevent the vehicle from
starting off on its own, always
move the selector lever to position P
or N and engage the parking brake
before leaving your vehicle with the
engine running.
Do not leave the vehicle unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a potential safety hazard.<
P ParkSelect only when the vehicle is
stationary. Transmission locks to
prevent rear wheels from turning.R ReverseSelect only when the vehicle is
stationary.

Electronic transmission control
module
If the indicator lamp comes on,
there is a malfunction in the
transmission system.
Bring the vehicle to a stop, select trans-
mission position "P", engage the
parking brake and switch the engine off
(ignition key to position 0).
Wait a few seconds, then start the
engine.
If the indicator lamp goes out after a
few seconds, normal transmission
performance has been restored. Drive
off normally.
If the indicator lamp does not go out, all
selector lever positions can still be
selected; however in the forward posi-
tions the vehicle has limited perfor-
mance as it drives only in 3
rd and 4
th
gear.
If this happens, avoid extreme engine
loads and consult the nearest BMW
center.
Never work in the engine
compartment when a drive gear
(forward or reverse) is engaged. If you
do this, the vehicle could move.<
For towing or jump-starting, refer to the
information beginning on page 134.

lamps accompanied by a periodic
clicking sound from the relay).To signal brieflyPress the lever up to but not beyond
the detent. It then returns to the center
position when released.
If the flashing of the turn signal
indicators and the clicking from
the relay are both faster than normal,
one of the turn signal indicators has
failed.<

To deceleratePress button (Ð) briefly:
If you are already driving with active
cruise control, the speed is decreased
by approx. 0.6 mph (1 km/h) every time
you tap the button.
Press and hold button (Ð):
With the cruise control active, the
system automatically reduces the
throttle opening to slow the vehicle.
When you release the button, the
system maintains and stores the
current speed.
To interrupt the cruise controlWhen the system is activated, press the
button. The indicator lamp stays on.
You can use the cruise control again
whenever you want by calling up the
speed that was stored last.
In addition, cruise control is interrupted
automatically:
>When the brakes are applied
>When you apply pressure to the
clutch pedal, or when you move the
automatic transmission selector lever
from D to N
>If you exceed or fall below the preset
speed for an extended period (by
depressing the accelerator, for
example).
To call up the stored speedPress button:
The vehicle accelerates to and main-
tains the last speed stored.

Automatic Stability Control plus Traction (ASC+T)

The conceptThis system optimizes vehicle stability
and traction, especially when just
starting off, when accelerating or when
going through curves.
ASC+T recognizes the danger present
in traction loss and will increase driving
stability and traction by reducing the
engine's output, and if necessary, by
applying the brakes to the rear wheels.
ASC+T is ready each time you start the
engine.
Indicator lamp
The indicator lamp in the instru-
ment cluster will go out shortly
after the ignition has been
switched on, refer to pages 18, 19.
The indicator lamp flashes:
ASC+T controls the drive and braking
forces.
The indicator lamp fails to go out
after the engine is started, or it
comes on during normal driving and
stays on:
There is a system malfunction or the
system was switched off with the
button. Consequently, interventions to
increase driving stability (as described
in the preceding column) are no longer
available. You can still drive the vehicle
perfectly well without ASC+T.
In the event of a fault, please consult
your BMW center, refer to
pages 18, 19.<
To switch off ASC+TPress the button; the indicator lamp
comes on and stays on.
The illustration depicts the arrangement
of the buttons if the vehicle is fully
equipped. This may vary, depending on
the equipment actually installed.
In the following rare situations, it may
be effective to switch off the ASC+T for
a brief period:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving with snow chains.
To maintain vehicle stability,
always drive with the ASC+T acti-
vated whenever possible.<

Dynamic Stability Control (DSC)
* Ð BMW 325i
The conceptThe Dynamic Stability Control (DSC)
maintains vehicle stability, even in crit-
ical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, it recognizes
unstable vehicle conditions, such as
under- or oversteering, and, as far as is
possible within the laws of physics,
helps keeping the vehicle on a steady
course by reducing engine speed and
brake applications to the individual
wheels.
DSC is operational every time you start
the engine. DSC incorporates the func-
tionality of the Automatic Differential
Brake (ADB) and the Cornering Brake
Control (CBC).
ADB (Automatic Differential Brake)
relies on selective braking applications
at the drive wheels to furnish the func-
tionality of a conventional limited-slip
differential for enhanced traction in crit-
ical driving conditions such as those
encountered on snow-covered road
surfaces, etc.
The ADB is in standby mode when DSC
is switched off.
Indicator lamp
The indicator lamp in the instru-
ment cluster will go out shortly
after the ignition has been
switched on, refer to pages 18, 19.
The indicator lamp flashes:
DSC controls the drive and braking
forces.
The indicator lamp stays lit:
DSC has been switched off via the
button; ADB is operational.
ADB control intervention is not indi-
cated.
The indicator lamp and the
brake warning lamps remain on
continuously:
The DSC, ADB and DBC have
been switched off via the button
or are defective.
The vehicle will remain completely
operational, however, without DSC. In
the event of a fault, please see your
BMW center, refer to pages 18, 19.
Indicator and warning lamps for
Canadian models.
To switch DSC off/activate ADBPress the DSC button briefly; the indi-
cator lamp comes on and stays on.
DSC is switched off; ADB is opera-
tional.
In the following rare situations, it may
be effective to activate the ADB for a
brief period:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving on snow-covered
grades, in deep snow, or on a snow-
covered surface that has been
packed down from being driven on
>When driving with snow chains.
Traction is increased by deactivating
the control systems that enhance trac-
tion under normal conditions.

Dynamic Stability Control (DSC)
* Ð BMW 325i
Switch the DSC and ADB offHold the DSC button down for at least
3 seconds. The indicator and the yellow
brake warning lamps will remain on
continuously.
The systems for enhancing stability and
traction are deactivated, and there is no
active braking intervention or torque
control.
To maintain vehicle stability,
always drive with the DSC
switched on whenever possible.<
Switch DSC and ADB back onPress the button again; the indicator
lamps will go out
The laws of physics cannot be
repealed, even with DSC. It will
always be the driver's responsibility to
drive in a manner that matches road
conditions. This is why you should not
use the additional safety margin the
system provides as an excuse to take
risks.
When ADB is in its standby mode, DSC
is deactivated; DSC does not intervene
to enhance vehicle stability under these
conditions.
Do not make any modifications to the
DSC system. Allow only authorized
technicians to perform service proce-
dures on the DSC.<
Dynamic Brake Control (DBC)DBC is an integral component of the
DSC system.
The system responds to sudden, high-
intensity applications of force to the
brake pedal by automatically braking
the vehicle with maximum boost to
achieve the shortest-possible braking
distances during "panic stops". This
system exploits all the benefits of ABS.
Do not reduce the pressure exerted
against the brake pedal until the
braking maneuver has been completed.
DBC is deactivated when you release
the brake pedal.
