SMG Sequential manual
transmission and automatic
transmission
Your BMW is equipped with the conve-
nience starting feature. Here, it is sufficient
to turn the ignition key only briefly to posi-
tion 3 'Start engine' and to let go of it right
away. The system responds by automati-
cally engaging the starter for a certain
period and allowing it to run until the engine
starts, after which it then disengages auto-
matically.
SMG Sequential manual
transmission
1.Press the brake pedal
2.Engage selector-lever position N
3.Start the engine.
If the engine does not start, engage
the last gear selected again, refer to
instrument cluster display, and then
engage selector-lever position N.<
Automatic transmission with
Steptronic
1.Press the brake pedal
2.Engage selector-lever position P or N
3.Start the engine.
Switching off engine
Do not remove the ignition key while
the vehicle is rolling, as otherwise the
steering wheel lock would engage while
steering.
When leaving the vehicle, remove the igni-
tion key and lock the steering.
When parking on a downhill incline, apply
the handbrake, as otherwise the vehicle
could roll away.<
Manual transmission
1.Turn the ignition key to position 1 or 0
2.Engage first or reverse gear.
SMG Sequential manual

1.Engage a drive position
2.Turn the ignition key to position 1 or 0.
A signal sounds if the idle position N is
engaged on stopping the engine.
Automatic transmission with
Steptronic
1.Engage selector-lever position P
2.Turn the ignition key to position 1 or 0.
Handbrake
The handbrake is primarily intended to pre-
vent the vehicle from rolling while parked;
it brakes the rear wheels.
Indicator lamp
The indicator lamp lights up, and an
acoustic signal also sounds when
starting off. The handbrake is
engaged.
Indicator lamp for Canadian mod-
els.
Engaging
The lever locks into place automatically;

If exceptional circumstances should
make it necessary to engage the
handbrake while the vehicle is in motion,

Driving
58 speed; thus, for example, a downshift
that would cause the engine to overrev
will not be executed by the system
>When the vehicle is stationary, the
transmission automatically downshifts
into first gear
>Shortly before dropping below a gear-
dependent minimum speed, the trans-
mission downshifts automatically even
without your intervention.
Malfunction
The warning lamp lights up and a
message appears on the Control
Display. There is a malfunction in
the transmission system. Avoid high loads.
While it will remain still possible to move
the selector lever to any desired position,
the transmission will revert to operation in
its default mode with only a limited number
of forward gears.
Have the system checked as soon as pos-
sible.
Information on jump-starting and towing
begins on page 185.
Overheating
The warning lamp lights up and a
message appears on the Control
Display. In addition, an acoustic
signal sounds. Overheating in the area of
the transmission. If possible, stop or drive
off quickly so that the system can cool
down.
Automatic transmission
with Steptronic*
In addition to the fully automatic mode, you
can also shift manually with Steptronic,
refer to page 59.
Selector-lever positions
P R N D M/S + –
Possible displays
P R N D DS M1 to M6
The selector lever position is indicated, and
in the manual mode the gear currently
engaged.
Changing selector-lever positions
An interlock prevents inadvertent gear-
shifts into selector-lever positions R and P.
To cancel the interlock, press the button on
the front of the selector lever knob, refer to
arrow.
Shiftlock
Press the brake pedal before shifting out
of P or N; the shift command will not be
executed unless the brake is applied.
To prevent the vehicle from creeping after
you select a driving position, maintain pres-
sure on the brake pedal until you are ready
to start.
To prevent the vehicle from rolling,
always select selector-lever posi-
tion P and engage the handbrake before
leaving the vehicle with the engine running.
Never leave an unattended vehicle with the
engine running, as such a vehicle repre-
sents a potential safety hazard.<

DSC Dynamic Stability Control
DSC optimizes vehicle stability during
acceleration and when starting from a full
stop, as well as optimizing traction. The
system recognizes any tendency for the
vehicle to assume an unstable attitude
such as oversteer or understeer; it then
counteracts this tendency with a combina-
tion of graduated reductions in engine
torque and selective braking intervention at
individual wheels. DSC provides optimal
stability within the limits defined by the
laws of physics.
The DSC is operational every time you start
the engine. DSC includes the functionality
of the DTC Dynamic Traction Control and
DBC Dynamic Brake Control, see below.
Indicator lamp
The indicator lamp goes out soon
after you start the engine.
The indicator lamp flashes:
DSC controls the drive and braking forces.
The indicator lamp stays lit:
DSC has been switched off via the button.
DTC Dynamic Traction Control
In special driving states, e.g. in deep snow,
DTC ensures maximum forward momen-
tum. The gain in forward momentum also
involves a reduction in driving stability.
DTC is active up to approx. 45 mph/
70 km/h, whereas DSC is only effective to
a limited degree.
You may find it useful to briefly activate
DTC under the following special circum-
stances:
>When rocking the vehicle and starting
off in deep snow or on loose road sur-
faces
>When ascending snow-covered hills,
and when driving in deep or on hard-
packed snow
>When driving with snow chains.
Activating DTC
>Press the DSC button briefly; the DTC
indicator lamp in the instrument cluster
lights up continuously.
Deactivating DTC again
Press the DSC button briefly again; the
DTC indicator lamp in the instrument clus-
ter goes out.
Switching off DSC
Press the DSC button until the DSC indica-
tor light in the instrument cluster lights up
continuously, however not longer than
approx. 10 seconds. DSC and DTC are
deactivated. In addition, the stability pro-
moting intervention of the active steering is
deactivated, refer to page 80.
A message appears on the Control Display.
Please note any supplementary information
that appears there.
To maintain optimal stability, drive
with the system on whenever possi-
ble.<
Reactivating DSC
Press the DSC button briefly; the indicator
lamp in the instrument cluster goes out.
