Starting the engine
Do not run the engine in enclosed areas;
otherwise, the inhalation of toxic exhaust
gases can cause loss of consciousness and
death. The exhaust gases contain carbon mon-
oxide, an odorless and colorless, but highly
toxic gas. Never leave an unattended vehicle
with the engine running; otherwise, such a vehi-
cle represents a potential safety hazard.
Before leaving the car with 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 repeated start attempts in
which the engine does not 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.
