Switching off the engine
You should never remove the igni-
tion key when the vehicle is in
motion, as the steering lock could
engage.
When you leave the vehicle, always
remove the ignition key and engage the
steering lock.<
Always engage the parking brake
when parking on downhill roads.
Engaging a gear may not sufficiently
secure the vehicle against rolling.<
Manual transmissionTurn the ignition key to position 1 or 0.Sequential M gearbox with
DrivelogicIf you turn the ignition key to position 1
or 0 with the selector lever in the for-
ward or reverse position, a gear auto-
matically remains engaged.
If you turn the ignition key to position 1
or 0 with the selector lever in position
N, a warning tone and the flashing gear
indicator in the SMG Drivelogic display
remind you that no gear is engaged to
secure the vehicle against rolling.
The warning stops after approx.
10 seconds. If you move the selector
lever into a forward or reverse position
during this time, a gear is automatically
engaged.
Parking brakeThe parking brake is designed primarily
to prevent the vehicle from rolling when
it is parked. It operates against the rear
wheels.To engageThe detent engages automatically, and
the indicator lamp in the instrument
cluster comes on when the ignition key
is in position 2, refer to page 18.To releasePull up slightly on the lever, press the
button and lower the lever.

If exceptional circumstances
make it necessary to engage the
parking brake while the vehicle is in
motion, do not pull it with excessive
pressure. Keep your thumb pressed
against the release button while care-
fully pulling the lever up.
Excessive pressure can lead to over-
braking and loss of traction – fishtailing
– at the rear axle.
The brake lamps do not come on when
the parking brake is engaged.
Always engage the parking brake when
parking on downhill roads. Engaging a
gear may not sufficiently secure the
vehicle against rolling.<
To avoid corrosion and one-sided
braking, apply the parking brake
from time to time when coasting to a
standstill – at a traffic light, for example
– provided that it is safe to do so.<
Manual transmission
When shifting gears in the 5th/6th
gear plane, be sure to press the
gearshift lever to the right in order to
prevent inadvertent selection of a gear
in the 3rd/4th gear plane. Do not hold
the vehicle in place on slopes by slip-
ping or 'riding' the clutch. Use the park-
ing brake instead. Riding the clutch
leads to severe and premature clutch
wear.<
ReverseSelect only when the vehicle is station-
ary. Press the shift lever to the left to
overcome the resistance.
As you do this, the backup lamps will
light up automatically when the ignition
key is in position 2.

Sequential M gearbox with Drivelogic*The conceptThe sequential M gearbox with
Drivelogic is an automated manual
gearbox with which clutching and shift-
ing is assumed by an electro-hydraulic
system.
The SMG Drivelogic is operated via two
shift paddles on the steering wheel and
the selector lever in the center console.
It offers the following functions:
>Sequential and automated shifting
mode
>Ability to choose between different
driving programs – Drivelogic
>Gradient assistance, refer to page 70
>Upshift display and shift lights, refer
to page 71
>RPM matching on downshifts
>Driving dependent functions:
The respective driving situation, e.g.
cornering, mountain driving or brak-
ing, is detected by sensors and taken
into account for shifting, e.g. to
achieve optimum gear selection dur-
ing deceleration and subsequent
acceleration
>Slip recognition at the rear axle for
increasing driving stability, e.g. dur-
ing downshifting on slippery road
surfaces>Operating safety through protection
against misshifting.
Under normal operating conditions, fuel
consumption is lowest when driving in
the first driving program of the auto-
mated shifting mode.
Selector lever positionsR: Reverse position
N: Neutral position
Forward position with one-touch mode:
>S: sequential mode
>D: automated mode
>+: upshifting in sequential mode
>–: downshifting in sequential mode.
The SMG Drivelogic is ready for opera-
tion from ignition key position two or
higher.
For your safety, it is only possible to
engage a driving position with the vehi-
cle stopped approx. two seconds after
engaging position 0 with the footbrake
depressed – shift-lock function.

DrivelogicDrivelogic makes various driving pro-
grams available to you.
Press the Drivelogic repeatedly until the
desired driving program is shown in the
SMG display of the instrument cluster,
refer to page 68.
In the automated mode you can select
from five driving programs ranging from
convenience mode/winter operation to
sporty and highly dynamic.
In the first automated driving program,
starting off takes place in second gear,
which is advisable under winter road
conditions with ice and snow.
In the sequential mode you can choose
from six driving programs ranging from
balanced, dynamic driving – 1 – to
sporty, puristic driving – 6. The sporty,
puristic driving program can only be
activated with the Dynamic Stability
Control (DSC) deactivated, refer to
page 83.
To maintain vehicle stability,
always drive with the DSC acti-
vated on whenever possible.<
Following each change between the
sequential and the automated mode,
the last driving program selected in the
respective mode is active. Exception:
instead of the last selected sequential
driving program 6, program 5 is acti-
vated only after the engine has been
started again.
Your vehicle is set so that when
the engine is started, the last
selected driving program saved in your
key is activated for each shifting
mode.<
Gradient assistanceThe gradient assistance enables start-
ing off on grades with virtually no roll-
back. It can be activated in the sequen-
tial and automated mode with the vehi-
cle stopped and can be used for both
forward and reverse driving.
The vehicle may roll slightly before
it is held by the gradient assis-
tance after releasing the footbrake.
Two seconds after the footbrake is
released, the vehicle begins to roll, as it
is no longer held with the gradient
assistance.<
1. Depress footbrake with vehicle
stopped
2. Activate the gradient assistance by
pulling the left paddle for at least
0.5 seconds. An increase in the
engine speed indicates that the gra-
dient assistance is activated
Briefly pulling the left paddle again
deactivates the gradient assis-
tance again.<
3. Release the footbrake and start off
within 2 seconds.
The gradient assistance must be reacti-
vated before each use.

The speed stored in memory is deleted.To store and maintain speed or to
acceleratePress button + briefly:
The system stores and maintains the
current vehicle speed. Every time you
tap the button, the speed increases by
approx. 0.6 mph / 1 km/h.
Press and hold button +:
The vehicle accelerates without pres-
sure on the accelerator pedal. When
you release the button, the system
stores and maintains the current speed.
If on a downhill gradient the
engine braking effect is not suffi-
cient, the controlled speed can be
exceeded. Speed can drop on uphill
grades if the engine output is insuffi-
cient. When cruise control is active, every tap
of the button reduces the speed by
approx. 0.6 mph / 1 km/h.
Press and hold button –:
With the cruise control active, the sys-
tem automatically reduces the throttle
opening to slow the vehicle. When you
release the button, the system stores
and maintains the current speed.To interrupt the cruise controlWhen the system is activated, press the
button. The indicator lamp stays on.
You can use the cruise control again
whenever you want by calling up the
speed that was stored last.
In addition, cruise control is interrupted
automatically:
>When the brakes are applied
>When pressing down the clutch pedal
>If you exceed or fall below the pro-
grammed speed for an extended
period – by depressing the accelera-
tor, for example
>Sequential M gearbox with
Drivelogic: when shifting in the
sequential mode – refer to page 67.
when shifting in the sequential mode,
refer to page:.
To recall the stored settingPress button:
The vehicle accelerates to and main-
tains the last speed stored.

Service interval displayRemaining distance to next
serviceThe displays shown in the illustration
appear for a few seconds when the
ignition key is in position 1 or higher or
after the engine is started.
The next service due appears with the
message OIL SERVICE or
INSPECTION, together with the dis-
tance remaining in miles – in kilometers
in Canada – before the next scheduled
service.
The computer bases its calculations of
the remaining distance on the preced-
ing driving style.
A flashing message and a '–' in front of
the number mean that the service inter-
val has already been exceeded by the
distance shown on the display. Please
contact your BMW center for an
appointment.
Check ControlDisplayWhen the ignition key is in position 2,
the following information and/or condi-
tions are indicated using symbols until
the conditions have been corrected.
1Inspect the low-beam and high-beam
headlamps, as well as the parking
lamps
2Door open
3Luggage compartment lid open
4Check tail or brake lamps
When you open the driver's door, after
having turned the ignition key to posi-
tion 0, you will hear an acoustic signal
for a few seconds to remind you that
the lamps have not been switched off.

Dynamic Stability Control (DSC)The conceptDSC maintains vehicle stability, even in
critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, it recognizes
unstable vehicle conditions, such as
understeering or oversteering, and,
within physically feasible limits, helps
keeping the vehicle on a steady course
by reducing the engine speed and
brake applications to the individual
wheels.
DSC starts up automatically each time
you start the engine.The laws of physics cannot be
repealed, even with DSC. The
results of driving irresponsibly rest with
the driver. We therefore urge you to
avoid using the additional 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 proce-
dures on the DSC. At first, you may
need some time to become accus-
tomed to this system's intervention.
However, it guarantees optimum drive
force and at the same time, the best
possible vehicle stability.<
Indicator lamp
The indicator lamp in the instru-
ment cluster will go out shortly
after the ignition has been
switched on, refer to page 20.
>Indicator lamp flashes: DSC is active
and is controlling the drive torque
based on driving conditions
>If the indicator lamp fails to go out
after the engine has been started, or
if it comes on during normal driving
and stays on: DSC has been deacti-
vated via the button or is defective.
Please consult your BMW center for
repairs.
You can continue to drive the vehicle
normally without DSC.

M Engine dynamics controlThe system – Sport mode – will cause
the engine to respond more spontane-
ously to any motion of the accelerator
pedal.Activating/deactivating Sport
modeActivating: with the ignition key in posi-
tion 2, press the SPORT button. The
indicator lamp will come on.
Each time you activate the sys-
tem, the vehicle may gain speed
without any additional pressure on the
accelerator pedal.<
Deactivating: press the SPORT button
again; the indicator lamp will go out.
The Sport mode is deactivated every
time the engine is started.
Brake force displayThe brake force display indicates to the
driver of the vehicle behind you how
hard you are braking your vehicle.
The display has two levels:
>Normal braking: the brake lamps
among the rear lamps and the center
brake lamp light up
>Hard braking or use of ABS: the tail
lamps light up with the same bright-
ness as the brake lamps and thereby
intensify the visual effect of the brake
lamps.
