Switching off the engine Parking brakeTurn the ignition key to position 1 or 0.
Never remove the ignition key
while the vehicle is rolling. The
steering locks, making it impossible to
steer the vehicle.
Always remove the ignition key and en-
gage the steering lock before leaving
the vehicle.
Vehicles with manual transmission:
Always engage the parking brake when
parking on slopes and inclined sur-
faces, since placing the lever in 1st gear
or reverse may not provide adequate
resistance to rolling.
Vehicles with automatic transmission:
Place the selector lever in "Park."<
Vehicles with automatic transmission
*:
The vehicle must be stationary and the
selector lever in "Park" before you can
remove the ignition key.
To engageThe lever engages automatically and
the "PARK BRAKE" or "BRAKE" (in
Canada "P") indicator lamp comes on in
the instrument cluster in ignition key
position 2. Refer to pages 22 and 23.To releasePull up slightly on the lever, press the
button and lower the lever.
The parking brake is primarily designed
to prevent the vehicle from rolling while
parked. It operates against the rear
wheels.390de042
If, in exceptional circumstances, it
should be 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 up the lever to apply mod-
erate 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 applied.
Vehicles with manual transmission:
Always engage the parking brake when
parking on slopes and inclined sur-
faces, since placing the lever in 1st gear
or reverse may not provide adequate
resistance to rolling.
Vehicles with automatic transmission:
Place the selector lever in "Park."<
To avoid corrosion, apply the parking
brake lightly from time to time when
coasting to a standstill (at a traffic sig-
nal, for instance), provided that it is safe
to do so.

ASC+T/DSC

Stability Control (DSC)
*
These systems contribute to additional
vehicle stability, especially during ac-
celeration and when cornering.
The DSC system enhances the benefits
of the ASC+T. In addition to optimizing
vehicle stability and traction during ac-
celeration or when starting from a
standstill, a further benefit is realized in
cornering. This, of course, is true only
within physically feasible limits.
The system activates automatically
each time you start the engine.390de359
Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly af-
ter you switch on the ignition.
Refer to page 24.
Indicator lamp flashes:
The system is actively regulating drive
torque in response to monitored vehicle
operating conditions.
If the indicator lamp fails to go out after
the engine is started, or if it comes on
during normal driving:
If the system has not been deactivated,
there is a system malfunction. The vehi-
cle remains operational, but without
ASC+T/DSC. Consult your authorized
BMW center for repair.
To deactivate the systemPress the button. The indicator lamp
will come on.
Depending on equipment options, the
button is marked with ASC or DSC.
With deactivated ASC+T/DSC you are
driving with conventional, unregulated
torque transfer.
We recommend that you deactivate the
system for increased traction:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving with snow chains.
Refer also to page 131.To reactivate the systemPress the button again; the indicator
lamp goes out.
The laws of physics cannot be re-
pealed, even with ASC+T/DSC.
Any consequences arising from traction
loss due to excessive vehicle speed re-
main the responsibility of the driver. We
therefore urge you to avoid using the
additional safety margin of the system
as an excuse for taking risks.<
For additional details concerning
ASC+T/DSC, please refer to the chap-
ter describing "Advanced technology"
on page 189.

Break-in procedureTo ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you ob-
serve the following: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
and the following road speeds during
this initial period:
BMW 528i: 100 mph (160 km/h)
BMW 540i: 106 mph (170 km/h)
Obey your local and state maximum
speed limits.
Refrain from using full throttle and avoid
pressing the accelerator beyond the
kickdown point.
Once you have driven 1,200 miles
(2,000 km), engine and vehicle speeds
can gradually be increased.
You should also comply with these
break-in procedures if the engine or dif-
ferential is replaced later in the course
of the vehicle service life.
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 with extra care
during the initial 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 com-
plete loss of traction, vehicle control
and braking effectiveness. Reduce your
speed on wet roads.<
Brake systemApproximately 300 miles (500 km) must
elapse before the brake pads and rotors
achieve the optimal pad-surface and
wear patterns required for trouble-free
operation and long service life later on.
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 traf-
fic conditions allow you to do so. To
avoid corrosion, repeat this procedure
from time to time.
The brake lamps do not come on
when the parking brake is applied.
Vacuum for the brake system servo unit
on your BMW is available only when the
engine is running. When you move the
car with the engine shut off Ð when
towing, for instance Ð substantially
higher levels of pedal force will be
required to brake the vehicle.<

Antilock Brake System (ABS)The conceptABS enhances active safety by helping
to prevent the wheels from locking un-
der braking. The reason: Locked wheels
are dangerous. When the front wheels
slide, the driver loses steering control
over the vehicle. Traction loss at the
rear wheels can cause the rear end to
break into an uncontrolled skid.
ABS is designed to meet two essential
requirements during every brake appli-
cation:
>To help provide vehicle stability
>To help retain steering and maneu-
vering capability on all types of road
surface (asphalt, cement, dirt, mois-
ture, snow and ice).
The system can achieve the shortest
braking distances possible under most
conditions (on straight-away and in
curves, on asphalt, ice, wet road sur-
faces, etc.).
Braking with ABSThe system becomes operative once
the vehicle exceeds a speed of approx.
6 mph (10 km/h). The ABS is deacti-
vated whenever the vehicle's speed
drops back below approx. 4 mph
(6 km/h). This means that the wheels
can lock in the final phase of a brake
application Ð a factor of no significance
in actual use.
If you are in a situation which requires
full braking, you will exploit the full ben-
efits of the ABS system if you apply
maximum brake pressure ("panic stop").
Since the vehicle maintains steering re-
sponsiveness, you can avoid possible
obstacles with a minimum of steering
effort, despite the full brake application.
The ABS system closed-loop control
circuit cycles in fractions of a second.
A pulsation at the brake pedal indicates
to the driver that ABS is active, that is,
that the vehicle is within its maximum
braking range. In addition, the audible
pulsation that accompanies the control
operation calls the attention of the
driver to the reduced traction between
the tires and the road surface (slippery
road surface), and serves as a reminder
that the speed of the car should be re-
duced to adapt to road conditions.On road surfaces which have a loose
layer on a firm base (on gravel or snow,
for instance), the braking distances with
ABS may be longer than with the
wheels locked. The same applies when
snow chains have been mounted. How-
ever, ABS continues to provide en-
hanced vehicle stability and steering re-
sponse under these conditions.
