Never allow the engine to operate with the
needle in the red overspeed sector of the
gauge.
To protect the engine, the fuel supply is
interrupted when you approach this sector.
Fuel gauge
When indicator lamp 1 begins to stay on
continuously, there are still approx.
2.1 gallons / 8 liters of fuel in the fuel tank.
Tank capacity: approx. 14.5 gallons/
55 liters.
If the tilt of the vehicle varies, for example
when you are driving in mountainous areas,
the needle may fluctuate slightly.
Fill the fuel tank well before it is
empty. Driving to the last drop of fuel
can prevent the engine from operating
properly and result in damage.<
When you switch on the ignition, the indi-
cator lamp comes on briefly to indicate an
operational check.

Service interval display
Remaining distance to next service
The displays shown in the illustration

key is in position 1 or after the engine is
started.
The next service due appears with the
message OIL SERVICE or INSPECTION,
together with the distance remaining in
miles – in kilometers in Canada – before the
next scheduled service.
The computer bases its calculations of the
remaining distance on the preceding driv-
ing style.
A flashing message and a minus sign in
front of the number mean that the service
interval has already been exceeded by the
distance shown on the display. Please con-
tact your BMW center for an appointment.

Dynamic Stability Control
DSC
The concept
This system optimizes driving stability and
traction, especially when just starting off,
when accelerating or when cornering. It
also maintains vehicle stability, even in crit-
ical driving situations.
DSC recognizes unstable vehicle condi-
tions, such as understeering or oversteer-
ing, and, within physically feasible limits,
helps keeping the vehicle on a steady
course by reducing engine speed and by
brake applications at individual wheels.
The DSC is operational every time you start
the engine. It includes the following func-
tions:
>Automatic Stability Control plus Trac-
tion ASC+T
>Dynamic Traction Control DTC
>Dynamic Brake Control DBC
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repealed even with DSC.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. We
therefore urge you to avoid using the addi-
tional safety margin of the system as an
excuse for taking risks.
Do not make any modifications to the DSC
system. Allow only authorized technicians
to perform service procedures on the
DSC.<
Indicator lamps
The indicator lamps in the instrument clus-
ter go out shortly after you switch on the
ignition.
Dynamic Stability Control DSC indi-
cator lamp flashes:
The system is active and governs
drive torque and braking forces.The indicator lamp stays lit:
Dynamic Stability Control DSC and
Dynamic Traction Control DTC have been
switched off via the button.
Dynamic Traction Control DTC indi-
cator lamp lights up permanently:
DTC has been deactivated via the
DSC button.
Dynamic Stability Control DSC indi-
cator lamp flashes:
Dynamic Traction Control DTC indi-
cator lamp lights up permanently:
DTC is actively regulating drive
torque and braking forces.
Interventions to increase stability are
being performed to a limited degree
only.<
The Dynamic Stability Control DSC
indicator lamp and yellow brake
warning lamp for Dynamic Brake
Control DBC light up continuously:
Dynamic Stability Control DSC,
Dynamic Traction Control DTC and
Dynamic Brake Control DBC are malfunc-
tioning.
Have the system repaired at your BMW
center.
Dynamic Stability Control DSC indi-
cator lamp and yellow brake warn-
ing lamp for Dynamic Brake Control
DBC for Canadian models:
The vehicle remains completely oper-
ational without the DSC, DTC and
DBC functions.<
In the event of a malfunction, please see
your BMW center.

them to be deactivated, the airbags have to
be deactivated with the vehicle ignition key
and the key switch on the outer passen-
ger's side of the instrument panel. Apart
from passengers, do not place any addi-
tional objects on the passenger seat. Do
not fit seat covers, seat cushion padding,
ball mats or other items to the passenger
seat unless they are specifically recom-
mended by BMW. Do not place any items
under the seat. Otherwise, the function of
the seat occupation detection could be
impaired.<
Indicator lamps
Airbag system operational
The airbag indicator lamp in the instrument
cluster indicates the operational readiness
of the entire airbag system and the safety
belt tensioners as of ignition key position 1.
The indicator lamp goes out after a few
seconds.
The indicator lamp in the central console
signals whether or not the passenger air-
bag system is activated or deactivated as
of ignition key position 1.
This lamp pertains only to the passen-
ger airbag system.<>The indicator lamp goes out after a few
seconds:
The passenger airbags are active, e. g.
when an adult is traveling in the vehicle
or the seat is unoccupied
>The indicator lamp lights up continu-
ously:
The passenger airbags are deactivated,
e. g. when a child is traveling in the vehi-
cle in the child-restraint system.
For more information on the operating prin-
ciple of the passenger airbag system and
seat occupation detection, refer to Auto-
matic deactivation of the passenger air-
bags.
Airbag system malfunction
A system malfunction could prevent
the system from responding in the
expected manner to an impact occurring
within its normal response range.
Please have the airbag system inspected
immediately at a BMW center.<
There is a fault in the airbag system
if the airbag indicator lamp behaves
as follows:
>The indicator lamp does not light up as
of ignition key position 1
>The indicator lamp remains on continu-
ously
>The indicator lamp lights up while the
vehicle is being driven.
