Ignition lock
0 Steering locked
The key can only be inserted or removed in
this position.
After removing the key, turn the steering
wheel slightly until it locks.
Vehicles with automatic transmission:
only move the selector lever from
position P with the engine running. To turn
the key back to position 0 or to remove it,
first place the selector lever in position P:
Interlock.<
1 Steering unlocked
A slight steering wheel movement often
makes it easier to turn the key from 0 to 1.
Individual current consumers are ready for
operation.
2 Ignition switched on
All vehicle systems are ready for operation.
3 Start engine
Starting the engine
Do not run the engine in closed
rooms, as otherwise the inhaling of
toxic exhaust gases can cause uncon-
sciousness and death. The exhaust gases
contain carbon monoxide, an odorless and
colorless, but highly toxic gas. Never leave
an unattended vehicle with the engine run-ning, as such a vehicle represents a poten-
tial safety hazard.<
Do not allow the engine to warm up by
leaving it running while the vehicle remains
stationary. Instead, begin to drive immedi-
ately at a moderate engine speed.
When starting the engine, do not press the
accelerator pedal.
Your BMW is equipped with the con-
venience starting feature. Here, it is
sufficient to turn the ignition key only briefly
to position 3 'Start engine' and to let go of it
right away. The system responds by auto-
matically engaging the starter for a certain
period and allowing it to run until the engine
starts, after which it then disengages auto-
matically. The automatic starting mode will
not operate or will be canceled if the bat-
tery voltage is low. The engine can be
started by jump-starting, refer to
page 192.<
Press the accelerator pedal halfway down
when starting if
>the engine fails to start on the first
attempt, for instance, if it is very hot or
cold
>the engine is started at very low tem-
peratures, as of approx. +5 7/Ð156,
at high altitudes over approx. 3,300 ft/
1,000 m.
Avoid frequent starting in quick suc-
cession or repeated start attempts in
which the engine does not start. Otherwise,
the fuel is not burned or inadequately
burned and there is a danger of overheat-
ing and damaging the catalytic converter. 1.Apply the handbrake
2.Gearshift lever in idle position
3.Press the clutch pedal
4.Start the engine.
Before leaving the vehicle with the
engine running, place the gearshift

Selector-lever positions
The current selector-lever position is dis-
played on the center console.
R: Reverse gear
N: Neutral, idle
Position for forward driving with one-touch
functions:
Sequential mode
+: manual upshifts
Ñ: manual downshifts
D: Drive mode.
The SMG is operational in ignition key posi-
tion 2.
Idle is automatically engaged if the
driver's door is opened with the
engine running and neither pedals, shift
paddles nor the selector lever are oper-
ated.
This is signaled by an acoustic signal and
the flashing gear indicator. The gear dis-
play N appears in the instrument cluster.
A driving position can only be selected with
the driver's door closed.
When the vehicle is unlocked, a buzzing
sound in the area of the transmission sig-
nals that the system is ready for opera-
tion.<
Shiftlock
For your safety a driving position can only
be engaged from the selector lever
position N with the vehicle stationary with
the brake pedal depressed.
Observe the following when driving
Start off quickly on slopes. Do not
hold the vehicle on a hill by pressing
the accelerator, but apply the handbrake
instead. Otherwise overheating can occur
in the area of the transmission.<
R Reverse
Select R only when the vehicle is com-
pletely stopped.
N Neutral: idle
Engage prior to every engine start, refer
also to page 50.
Sequential mode
After every engine start, as soon as the
selector lever is brought into a forward gear
position and the brake is pressed, the
sequential mode is activated.
The gear is changed using the shift paddles
or selector lever.
Driving off is also possible in second gear,
e.g. when there is snow on the roadway.
D Drive mode
In the Drive mode, all forward gears are
shifted automatically.
To switch from the sequential to Drive
mode: briefly press the selector lever to the
right towards D.
For rapid acceleration, e.g. overtaking,
press the accelerator pedal as far down as
it will go Ð kickdown.
Kickdown:
The kickdown mode provides maximum
acceleration.
Press the accelerator pedal beyond the
full-throttle resistance point.
To return to the sequential mode: briefly
press the selector lever back to the right

towards D or change the current gear using
the shift paddles or selector lever.
Gear changes
Using selector lever
>To shift up, briefly press the selector
lever towards +
>To shift down, briefly press towards Ñ.
Using shift paddles on steering
wheel
>To shift up, pull one of the shift paddles
>To shift down, press.
You accelerate from higher gears, e.g.
when overtaking, by shifting down manu-
ally.
In the following situations, the SMG in the
sequential mode assists you:
>Upshifts and downshifts are executed
only when they will result in a plausible
combination of engine and vehicle
speed; thus, for example, a downshift
that would cause the engine to overrev
will not be executed by the system
>When the vehicle is stopped, the trans-
mission automatically downshifts into
first gear
>Shortly before dropping below a gear-
dependent minimum speed, the trans-
mission downshifts automatically even
without your intervention.

The gear currently selected, the selected

Malfunctions
Indicator lamp
If the indicator lamp lights up, a
malfunction has occurred in the
transmission system.
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.
If this happens, avoid extreme engine loads
and consult the nearest BMW center.
Warning tone
In case of overheating in the area of the
transmission, an acoustic signal indicates
that you should stop or start off quickly if
possible so that the system can cool down
again.
