Ignition lock
0 Steering locked
This is the only position in which the ignition key
can be inserted or removed.
After removing the key, turn the steering wheel
slightly to the left or right until the lock engages.
If the key is not removed, an acoustic signal
sounds when the driver's door is opened.
Interlock
Vehicles with automatic transmission:
In order to turn the key back to position0 or to
remove it, move the selector level into position
P first.
1 Steering unlocked
You will find that it is often easier to turn the
ignition key from position0 to 1 if you move the
steering wheel slightly to help disengage the
detent.
Individual electrical equipment and accessories
are available for use.
2 Ignition switched on
All systems are operational.
3 Starting engine
Engine
Engine idle speed is controlled by the engine
computer system. Increased speeds at start-up are normal and should decrease as the engine
warms up. If engine speed does not decrease,
service is required.
To prevent the battery from discharging, always
deactivate electrical devices that are not in use.
Switch the ignition off when the vehicle is not
being driven.
Do not leave the engine running in
enclosed spaces. Otherwise, inhaling the
hazardous exhaust gases could lead to uncon-
sciousness and death. The exhaust gases con-
tain carbon monoxide, an odorless and color-
less, but highly toxic gas.
Do not leave the vehicle unattended with the
engine running. An unattended vehicle with a
running engine poses a safety hazard.
Before you leave the vehicle with the engine
running, place the engine in idle first or engage
the P position and apply the parking brake. If
you fail to do this, the vehicle could move.<
Starting the engine
Do not press the accelerator pedal while start-
ing the engine.
Do not let the engine warm up in idling position.
Instead, begin to drive at moderate engine
speeds.
Vehicles with manual transmission:
Step on the clutch when starting the vehi-
cle. A lockout prevents the engine from starting
if the clutch is not depressed.<
Do not end the starting procedure too early, but
do not continue it for more than 20 seconds.
Release the ignition key immediately when the
engine starts.
If the engine fails to start on the first attempt,
e.g. if it is very hot or cold:
Press the accelerator pedal halfway down.
Cold starts at very low temperatures, below
approx. +57/–156, and at high altitudes,
above 3,300 ft/1,000 m:

To release
Pull up slightly on the lever, press the button
and lower the lever.
If, in exceptional circumstances, it should
be necessary to engage the parking brake
while the vehicle is in motion, do not pull it with
excessive pressure. Keep the release button on
the parking brake lever pressed down while
pulling up the lever.
Excessive pressure can lead to overbraking and
loss of traction, fishtailing, at the rear axle.
The brake lamps do not come on when the
parking brake is engaged.<

Sequential manual gearbox
SMG*
The concept
The sequential manual gearbox SMG is an
automated manual gearbox with which clutch-
ing and shifting is assumed by an electro-
hydraulic system.
The SMG is operated via two shift paddles on
the steering wheel and the selector lever in the
center console.
It offers the following functions:
>Optionally manual or automatic operation:
sequential mode or drive mode
>Ability to choose between two different
driving programs: standard or Sport, refer to
page41
>Protection against misshifting, and auto-
matic downshifting at minimum engine rpm
even in sequential mode
>Kickdown function in the drive mode
>Acceleration assistant, refer to page42.
The SMG is ready for operation when the igni-
tion key is in position 2.
Selector lever positions
You can see the current selector lever position
in the center console.
>R: Reverse
>N: Neutral
>One-touch functions for the sequential
mode
+: manual upshifting
–: manual downshifting>D: Drive mode.
N is automatically selected if the driver's
door is opened while the engine is run-
ning and the driver does not actuate the pedals,
the shift paddles or the selector lever.
This is accompanied by an acoustic signal and a
flashing N in the instrument cluster.<
Gear indicator

While the vehicle is stationary and before shift-
ing out of N, depress the footbrake, as other-
wise the desired gear shift is not executed.
R Reverse
Select only when the vehicle is stationary.
Sequential mode
Each time the engine is started, the sequential
mode is activated as soon as you move the
selector lever towards the right while depress-
ing the brake pedal.
The gear is changed via the shift paddles or the
selector lever.
It is also possible to drive off in second gear, e.g.
on slippery roads.
D Drive mode
In the drive mode all forward gears are shifted
automatically.
To switch from sequential to drive mode: tap

Technology for safety and driving convenience

Driving stability control
systems
Your BMW is equipped with a series of systems
that help maintain driving stability even in
adverse driving situations.
Antilock Brake System ABS
ABS keeps the wheels from locking during
braking. Steering stability is maintained even
during full brake applications. In this way, active
safety is enhanced.
ABS is operational each time the engine is
started. Braking safely, refer to page69.
Electronic brake-force distribution
The system controls brake-force application at
the rear wheels in order to obtain increased sta-
bility in the vehicle's braking response.
Dynamic Brake Control DBC
When the brake pedal is depressed quickly, this
system automatically supplies maximum brake-
servo boost, thereby helping to keep the vehi-
cle's braking distance as short as possible dur-
ing full brake applications. At the same time, the
benefits of the ABS are also exploited.
As long as you are braking, do not reduce pres-
sure on the brake pedal. When the brake pedal
is released, the DBC is switched off.
Dynamic Stability Control DSC
DSC prevents slip at the drive wheels while
starting off and accelerating the vehicle. DSC
also recognizes unstable vehicle conditions,
such as fishtailing or nose-diving. In these
cases, and subject to physical limits, DSC helps
to keep the vehicle on a steady course by
reducing engine speed and by applying brakes
at individual wheels.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. Therefore, do not
limit the additional safety margin by practicing
risky driving.<
Dynamic Traction Control DTC
DTC is a variant of the DSC in which forward
momentum is optimized for special road condi-
tions, e.g. snow-covered roads that have not
yet been cleared. The system ensures maxi-
mum forward momentum, but driving stability is
limited. Therefore, drive carefully in accordance
with conditions.
In the following exceptional circumstances, it
may be effective to activate the DTC for a short
period:
>When driving on snow-covered grades, in
slush or on uncleared, snow-covered roads
>When rocking the vehicle or starting off in
deep snow or on loose surfaces
>When driving with snow chains.
Activating DTC
Press the button briefly; the DTC indicator lamp
lights up in the instrument cluster.
Reactivating DTC
Press the button again; the DTC indicator lamp
goes out in the instrument cluster.

Air distribution
You can direct airflow onto the win-
dows , toward the upper body
and into the footwell . All interme-
diate settings are possible.
Air supply/blower
Turn the rotary control to adjust the
air supply. Both heating and ventila-
tion become more effective as the air
supply rate is increased.
Turn the rotary control toward zero:
The blower and the heating are turned off, and
the air supply is stopped.
Temperature
In order to increase the temperature
of the passenger compartment, turn
to the right toward the red zone.
Air conditioning
The air is cooled and dehumidified
and, depending on the temperature
setting, rewarmed.
Depending on the weather, the wind-
shield may fog over briefly when the engine is
started.
Condensation forms during operation of
the air conditioning system, which then
exits under the vehicle. Traces of condensed
water on the ground underneath the vehicle are
thus normal.<
Outside air/recirculated air mode
If there are unpleasant odors in the
outside air, you can temporarily block
the supply of incoming air. The sys-
tem then recirculates the air currently
within the vehicle.
If the windows fog over in the recirculated
air mode, switch this mode off and
increase the air supply as required. Do not use
the recirculated-air mode continuously over a
long period of time as this would otherwise
reduce the air quality in the interior of the vehi-
cle.<
Rear window defroster
The indicator lamp lights up when
the rear window defroster is active.
The rear window defroster switches
off automatically.
Ventilation
You can adjust the blower controls for the upper
body area to obtain the optimum airflow rates
and directions for your personal requirements:
1Rotary dials for opening and closing the
vents at any setting desired
2Slide for adjusting airflow direction
Microfilter
The built-in microfilter removes dust and pollen
from the incoming air and in the recirculated air
mode. Your BMW center will replace this filter
during the regularly scheduled maintenance. A
substantial reduction in airflow indicates that
the filter needs to be replaced earlier.
