tap the button, the speed increases by
approx. 0.6 mph (1 km/h).
Press and hold button (+):
The vehicle accelerates without pres-
sure on the accelerator pedal. When
you release the button, the system
stores and maintains the current speed.
If, on a downhill gradient, the
engine braking effect is not suffi-
cient, the controlled speed can be
exceeded. Speed can drop on uphill
grades if the engine output is insuffi-
cient.<
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 registers and maintains 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 depress the clutch pedal
>If you exceed or fall below the
programmed speed for an extended
period (by depressing the acceler-
ator, for example). To recall the stored settingPress button:

Dynamic Stability Control (DSC)DSC maintains vehicle stability, even in
critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as enhancing
traction. In addition, the system recog-
nizes unstable vehicle conditions
(understeering or oversteering, for
example) and holds the vehicle on a
sure course by intervening via the
engine and by braking at the individual
wheels.
The system starts up automatically
each time you start the engine.Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition.
Refer to page 17.
Indicator lamp flashes:
The system is active and governs drive
and braking force.
If the indicator lamp fails to go out after
the engine is started, or if it comes on
during normal driving and stays on:
There is a system malfunction or the
system was deactivated with the button.
You can continue to drive the vehicle
normally, but without DSC. Please
consult your BMW center for repairs.
To deactivate the systemPress the button, the indicator lamp
lights up and remains on continuously.
When DSC is deactivated, you are
driving with conventional power
transfer.
In the following exceptional circum-
stances, it may be effective to deacti-
vate the DSC for a short period:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving with snow chains.39mde124
To reactivate the systemPress the button again; the indicator
lamp goes out.
The laws of physics cannot be
repealed, even with DSC. An
appropriate driving style always
remains the responsibility of the driver.
Do not use the extra safety margins
furnished by these systems as an
excuse for taking unnecessary risks. 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 pedal.

To ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you
observe the following.
Your BMW M5 is a masterpiece of
superlative technology. To ensure
that you derive maximum satisfaction
from its extensive array of advanced
features while simultaneously creating
the basis for many years of driving plea-
sure, we urge you to observe the
following precautions during the initial
period of operation.<
Engine and differentialUp to 1,200 miles (2,000 km):
Drive at varying engine speeds and
road speeds, but do not exceed
5,500 rpm or 105 mph (170 km/h)
during this period.
Comply with all speed limits.
Do not depress the accelerator pedal to
the full-throttle position.
Following the Break-in inspection at
1,200 miles (2,000 km), you can gradu-
ally increase engine or road speeds.
You should also comply with these
break-in procedures if the engine or
differential is replaced at a later point.
TiresOwing to technical factors associated
with their manufacture, tires do not
achieve their full traction potential until
an initial break-in period has elapsed.
Thus drive with extra care during the
initial 200 miles (300 km).
Comply with all speed limits.
When the vehicle is operated on
wet or slushy roads, a wedge of
water may from 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 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
traffic 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
vehicle with the engine shut off Ð when
towing, for instance Ð substantially
higher levels of pedal force will be
required to brake the vehicle. optimally after about 300 miles
(500 km). During the run-in period, treat
the engine with care and do not engage
it at high engine speeds.

OverviewControlsMaintenanceRepairsDataIndex
Driving notes Antilock Brake System
Brakes:
Do not rest your foot on the brake
pedal while driving. Even light but
consistent pedal pressure can lead to
high temperatures, brake wear and
possibly even brake failure.
Aquaplaning:
When driving on wet or slushy roads,
reduce vehicle speed. If you do not, a
wedge of water may form between the
tires and the road surface. This
phenomenon is referred to as aqua-
planing, or hydroplaning, and can lead
to partial or complete loss of traction,
vehicle control and braking effective-
ness.
Driving through water:
When there is water on the roads, do
not drive in it if it is deeper than 1 ft
(30 cm). If the water is at that depth,
drive only at walking speed, otherwise
the vehicle can sustain damage to the
engine, the electrical systems and the
transmission.
Rear parcel tray:
Do not place heavy or hard objects on
the rear parcel tray. If you do so, they
could pose a danger to vehicle occu-
pants during a braking or evasive
maneuver.
Clothes hooks:
When suspending clothing from the
hooks, ensure that they will not obstruct
the driver's vision. Do not hang any
heavy objects on the hooks, otherwise,
passengers could be injured e.g. during
any hard braking or evasive maneuvers,
or during an accident.<
The conceptThe Antilock Brake System (ABS) keeps
the wheels from locking during braking,
thereby enhancing active driving safety.Braking with ABSIf you are in a situation that requires full
braking, you will exploit the full benefits
of the ABS system if you apply
maximum pedal pressure ("panic stop").
Since the vehicle maintains steering
responsiveness, you can avoid possible
obstacles with a minimum of steering
effort, despite the full brake application.
Pulsation at the brake pedal combined
with sounds from the hydraulic circuits
indicates to the driver that ABS is in its
active mode.

108n
Brake systemBrake fluid level 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 brake system's hydraulic
circuits.
Proceed to the nearest BMW
center. Higher brake application
pressure may be necessary under these
conditions, and the vehicle may exhibit
a slight tendency to pull to one side
when the brakes are applied. Braking
distances may also be longer. Please
remember to adapt your driving style
accordingly.<
Disc brakesLimited vehicle use, extended periods
with the vehicle parked or in storage,
and operating conditions in which
braking is restricted to gentle, low-
pressure applications will all increase
the tendency for corrosion to form on
the rotors; this is often accompanied by
a simultaneous accumulation of
contamination 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 a good idea 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 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.
By minimizing the loads placed on the
brake system, this strategy helps
ensure that optimal brake system
response will remain available at all
times.
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.
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
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.<

1. Turn the cap counterclockwise
slightly in order to allow accumulated
pressure to escape
2. If the coolant is low, slowly add
coolant until the correct level is
reached Ð do not overfill.
Comply with the applicable envi-
ronmental laws regulating the

Brake fluid level
The warning lamp for the brake
system hydraulic circuits comes
on and/or the message "CHECK
BRAKE FLUID" appears in the
Check Control panel:
Brake fluid level too low.
To add brake fluidThe brake fluid reservoir is located
under the microfilter housing on the
driver's side of the vehicle. For adding
brake fluid or for determining 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 may result in extended
brake pedal travel. If this occurs, refer
to the information on page 108.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability of the brake system, have the
brake fluid changed every two years at
a BMW center. Refer also to the Service
and Warranty Information Booklet (US
models) or the Warranty and Service
Guide Booklet (Canadian models).
Brake fluid is toxic and damages the
vehicle's paint. You should always store
it in its original container and in a loca-
tion which is out of reach of children.
Do not spill the 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.<
