Starting the engine
General information
Enclosed areas
Do not let the engine run in enclosed
areas; otherwise, breathing of exhaust fumes
may lead to loss of consciousness and death.
The exhaust gases contain carbon monoxide, an
odorless and colorless but highly toxic gas.◀
Unattended vehicle
Do not leave the vehicle unattended with
the engine running; doing so poses a risk of dan‐
ger.
Before leaving the vehicle with the engine run‐
ning, set the parking brake and place the trans‐
mission in position P or neutral to prevent the
vehicle from moving.◀
Frequent starting in quick succession
Avoid repeated futile attempts at starting
the car and avoid starting the car frequently in
quick succession. Otherwise, the fuel is not
burned or is inadequately burned, and there is
the danger of overheating and damaging the
catalytic converter.◀
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving at mod‐
erate engine speeds.

Socket for OBD Onboard
Diagnosis
Position
There is an OBD socket on the driver's side for
checking the primary components in the vehicle
emissions.
Emissions
▷The warning lamp lights up:
Emissions are deteriorating. Have
the vehicle checked as soon as pos‐
sible.
Canadian model: warning light indi‐
cates the engine symbol.
▷The warning lamp flashes under certain cir‐
cumstances:
This indicates that there is excessive misfir‐
ing in the engine.
Reduce the vehicle speed and have the sys‐
tem checked immediately; otherwise, seri‐
ous engine misfiring within a brief period can
seriously damage emission control compo‐
nents, in particular the catalytic converter.
Fuel cap
The indicator lamp lights up.
If the fuel cap is not properly tightened,
the OBD system may conclude that fuel
vapor is escaping. If the cap is then tightened,
the display should go out in a short time.
Data memory
Your vehicle records data relating to vehicle op‐
eration, faults and user settings. These data are
stored in the remote control and can be read out
with suitable devices, particularly when the ve‐
hicle is serviced. The data obtained in this way
provide valuable information for service proc‐
esses and repair or for optimizing and develop‐
ing vehicle functions further.
In addition, if you signed a service contract for
BMW Assist, certain vehicle data can be sent
directly from the vehicle to facilitate the desired
services.
