Avoid frequent starting in quick succes-
sion or repeated starting attempts in
which the engine does not start. Otherwise, the
fuel is not burned or inadequately burned and
there is a danger of overheating and damaging
the catalytic converter.<
Switching off engine
Do not remove the remote control from
the ignition lock while the vehicle is roll-
ing, otherwise the steering-wheel lock would
engage while steering.
When leaving the vehicle, always take the
remote control with you.
When parking on a downhill incline, apply the
handbrake, otherwise the vehicle could roll
away.<
Manual transmission
1.Briefly press the Start/Stop button with the
vehicle stopped.
2.Shift into first gear or reverse.

Handbrake
The handbrake is primarily intended to prevent
the vehicle from rolling while parked; it brakes
the rear wheels.
Indicator lamp
The indicator lamp lights up, and a sig-
nal also sounds when starting off. The
handbrake is applied.
Indicator lamp for Canadian models.
Engaging
The lever locks in position automatically.
Releasing
Pull slightly upwards, press the button and
lower the lever.
If exceptional circumstances should
make it necessary to apply the handbrake
while the vehicle is in motion, do not pull it too
strongly. In doing so, continuously press the
button of the handbrake lever. Otherwise
excessive pressure can lead to the rear wheels
locking up and loss of traction – fishtailing – at
the rear axle.<
To prevent corrosion and one-sided brak-
ing action, occasionally apply the hand-
brake lightly when the vehicle is slowly coming
to a stop if the traffic conditions are suitable.
The brake lamps do not light up when the hand-
brake is applied.<

Socket for OBD Onboard
Diagnostics interface
Components which are decisive for the
exhaust-gas composition can be checked via
the OBD socket with a device.
This socket is located to the left on the driver's
side, on the underside of the instrument panel
under a cover.
Exhaust-gas values
The warning lamp lights up. The
exhaust-gas values worsen. Have the
vehicle checked as soon as possible.
Display of the previously described
malfunction in Canadian models.
The lamp flashes under certain conditions. This
is a sign of excessive misfiring of the engine. In
this case you should reduce speed and drive to
the nearest BMW center as soon as possible.
Heavy engine misfiring causes serious damage
to the emission-relevant components, espe-
cially the catalytic converter, within a short time.
If the fuel filler cap is not properly tight-
ened, the OBD system will assume that
fuel vapor escapes. Then a display lights up. If
the cap is then tightened, the display will go out
within a few days.<
Event Data Recorders
Your vehicle may be equipped with one or sev-
eral measuring and diagnosis modules, or with
a device for recording or transmitting certain
vehicle data or information. If you have also
signed a contract of participation for
BMW Assist, certain vehicle data can be trans-
mitted or recorded to enable corresponding
services.
Care
Important information on the care and mainte-
nance of your BMW is contained in the Caring
for your vehicle brochure.
