Starting the engine
Do not run the engine in closed rooms,
otherwise the inhalation of toxic exhaust
gases can cause unconsciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless, but highly toxic gas.
Never leave an unattended vehicle with the
engine running, otherwis e such a vehicle repre-
sents a potential safety hazard.
Before leaving the car wi th the engine running,
place the transmission in neutral or move the
selector lever to position P and set the parking
brake to prevent the car from moving. <
Avoid frequent starting in quick succes-
sion as well as repeat ed start attempts in
which the engine does no t start. Otherwise, the
fuel is not burned or incompletely burned and
there is a danger of overheating and damaging
the catalytic converter. <
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving right
away, but at moderate engine speeds.

Parking brake
The concept
Your BMW is equipped with an electromechan-
ical parking brake that can be set and released
by using a button.
The parking brake is primarily used to prevent
the vehicle from rolling when it is parked.
When the vehicle is stationary, the parking
brake acts on the rear wheels via an electrome-
chanical mechanism. When the vehicle is rolling
or being driven, the parking brake acts on the disc brakes of the front and rear wheels via the
hydraulic brake system.
Setting the brake
Pull the button. The parking brake is set.
The indicator lamp in the instrument
cluster and the LED on the button light
up red. The parking brake is set.
Indicator lamp in Canadian models.
To set the parking brake, the remote control
does not need to be in the ignition lock.
While driving
In the rare case that the parking brake needs to
be used while driving, pull the button for a
lengthy period:
The vehicle brakes hard while the button is
being pulled. The indicator lamp in the instrument
cluster lights up red, a sound is issued
and the brake lamps light up.
Indicator lamp in Canadian models.
As soon as you brake the vehicle almost to a
standstill, approx. 2 mph/3 km/h, the parking
brake remains set.
Releasing
Take the remote cont rol with you when
leaving the vehicle so that children, for
example, cannot release the parking brake. <

Upshifts and downshifts are executed only
when they will result in a plausible combination
of engine and vehicle speed; thus, for example,
a downshift that would cause the engine to
overrev will not be executed by the system. The
gear selected is briefly displayed in the instru-
ment cluster, followed by the gear actually
in use.
Shifting gears via sh ift paddles* on the
steering wheel
The shift paddles allow yo u to shift gears with-
out taking your hands off of the steering wheel.
> When you use the shift paddles on the
steering wheel to shif t gears in automatic
mode, the transmission switches to

box components in which the gears are
changed without loss of torque.
You operate the transmission using the selector
lever and two shift paddles on the steering
wheel.
It offers the following functions:
> Selection between manual and automatic
operation: sequential mode or drive mode
> Automatic downshifting and protection
against selecting the wrong gear, even in
sequential mode
> Launch Control acceleration assistant, refer
to page 58
> Automatic double de-clutch
System limitations
This transmission is equipped with an over-
heating protection system that protects the
clutches against extremely high loads.
