Ignition switched on
All systems are operational.
Starting the engine
Engine idle speed is controlled by the engine
computer system. Increased speeds at start-up
are normal and should decrease as the engine
warms up. If engine speed does not decrease,
service is required.
To prevent the battery from discharging, always
deactivate electrical devices that are not in use.
Switch the ignition off when the vehicle is not
being driven.
Do not leave the engine running in
enclosed spaces. Otherwise, inhalation of
the hazardous exhaust gases could lead to
unconsciousness and death. The exhaust
gases contain carbon monoxide, an odorless
and colorless, but highly toxic gas. Do not leave
the vehicle unattended with the engine running.
An unattended vehicle with a running engine
poses a safety hazard.
Before leaving the car with the engine running,
place the transmission in idle or move the
selector lever to position P and apply the park-
ing brake to prevent the car from moving.<

Cruise control*
The concept
Cruise control is available at speeds of at least
approx. 20 mph/30 km/h. The car stores and
maintains the speed that you specify with the
lever on the steering column.
Do not use cruise control if conditions are
unfavorable for driving at a constant
speed, e.g. due to winding roads, dense traffic,
or poor road conditions such as snow, rain, ice,
loose surface, etc. Otherwise, you could lose
control of the vehicle and cause an accident.<

Technology for driving comfort and safety
Driving stability control
systems
Your BMW is equipped with a s eries of systems
that help maintain driving stability even in
adverse driving situations.
Antilock Brake System ABS
ABS keeps the wheels from locking during
braking. Steering stability is maintained even
during full brake applications. In this way, active
safety is enhanced.
ABS is operational each time the engine is
started. Braking safely, refer to page75.
Electronic brake-force distribution
The system controls brake-force application at
the rear wheels in order to obtain increased sta-
bility in the vehicle's braking response.
Dynamic Brake Control DBC
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. At the same time, the benefits of the ABS
are also exploited.
As long as you want full braking to continue, do
not reduce pressure on the brake.
Dynamic Stability Control DSC
DSC prevents slip at the drive wheels while
starting off and accelerating the vehicle. DSC
also recognizes unstable vehicle conditions,
such as fishtailing or nose-diving. In these
cases, and subject to physical limits, DSC helps
to keep the vehicle on a steady course by
reducing engine speed and by applying brakes
at individual wheels.
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. Therefore, do not limit the additional safety margin by practicing
risky driving.<
Deactivating DSC
Press the button for at least 3 seconds; the indi-
cator lamp for DSC lights up in the instrument
cluster. Dynamic Traction Control DTC and
DSC have been deactivated simultaneously. No
more interventions to increase stability and for-
ward momentum are carried out.
To enhance vehicle stability, reactivate DSC as
soon as possible.
Activating DSC
Press the button again; the indicator lamp goes
out in the instrument cluster.
Checking
The indicator lamp flashes:
DSC controls the drive forces and
brake forces.
The indicator lamp is lit:
DSC has been deactivated completely.
Dynamic Traction Control DTC
DTC is a variant of the DSC in which forward
momentum is optimized for special road condi-
tions, e.g. snow-covered roads that have not
yet been cleared. The system ensures maxi-
mum forward momentum, but driving stability is
limited. Therefore, drive carefully in accordance
with conditions.
