Handbrake
The handbrake is primarily intended to prevent
the vehicle from rolling while parked; it brakes
the rear wheels.
Indicator lamp
The indicator lamp lights up, and a sig-
nal also sounds when starting off. The
handbrake is applied.
Indicator lamp for Canadian models.
Engaging
The lever locks in position automatically.
Releasing
Pull slightly upwards, press the button and
lower the lever.
If exceptional circumstances should
make it necessary to apply the handbrake
while the vehicle is in motion, do not pull it too
strongly. In doing so, continuously press the
button of the handbrake lever. Otherwise
excessive pressure can lead to the rear wheels
locking up and loss of traction – fishtailing – at
the rear axle.<
To prevent corrosion and one-sided brak-
ing action, occasionally apply the hand-
brake lightly when the vehicle is slowly coming
to a stop if the traffic conditions are suitable.
The brake lamps do not light up when the hand-
brake is applied.<

Manual transmission
While shifting in the 5th/6th gear lane,
press the gearshift lever toward the right,
otherwise accidental shifting into the 3rd or 4th
gear could result in engine damage.<
Reverse gear
Select only when the vehicle is stationary.
When pressing the gearshift lever to the left,
overcome some resistance.
SMG Sequential Manual
Transmission*
The concept
The SMG Sequential Manual Transmission is
an automated manual transmission in which an
electrohydraulic system handles the clutching
and gear changes.
The SMG is operated with the selector lever
and two shift paddles on the steering wheel.
It offers you the following functions:
>Optional manual or automatic operation:
Sequential mode or Drive mode
>You have a choice of two driving programs:
Normal or Sport, refer to Dynamic Driving
Control page63
>Automatic downshifting and prevention of
incorrect shifting even in Sequential opera-
tion
>Acceleration assistant, refer to page64
Selector lever positions
>R: Reverse gear
>N: Neutral
>One-touch functions for Sequential mode:
+: manual upshifting
–: manual downshifting
>D: activate/deactivate the Drive mode
The transmission automatically shifts
into N if the driver's door is opened with
the engine running and neither the pedals, the
shift paddles nor the selector lever are oper-
ated.
This is signaled by an acoustic signal and the
flashing display N in the instrument cluster; a
message appears on the Control Display.<
Gear display
R N 1 to 6
The currently engaged gear is displayed, pre-
ceded by a D in Drive mode.
It is only possible to recognize whether
the desired selector lever position is
engaged with this display.<

Shiftlock
Press the brake pedal before shifting out of N;
the shift command will not be executed unless
the brake is applied.
R Reverse
Select only when the vehicle is stationary.
Sequential mode
After every engine start, as soon as the selector
lever is pushed to the right and the brake pedal
is depressed, the Sequential mode is activated.
You can shift up and down using the shift pad-
dles or the selector lever. You do not need to
remove your foot from the accelerator to do so.
It is also possible to start off in second gear, e. g.
in slippery conditions.
In the following situations, SMG thinks for you:
>Upshifts and downshifts are executed only
when they will result in a plausible combina-
tion 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 stationary, the trans-
mission automatically downshifts into first
gear.
>Shortly before dropping below a gear-
dependent minimum speed, the transmis-
sion downshifts automatically even without
your intervention.
D Drive mode
In the Drive mode, all forward gears are shifted
automatically.
Shifting from Sequential mode to Drive mode:
press selector lever to the right toward D.
Kick-down: for rapid acceleration, e. g. when
passing, press the accelerator pedal as far
down as it will go. You achieve maximum accel-
eration.
To switch back into the Sequential mode: press
selector lever to the right again toward D or shift
using the shift paddles or the selector lever.Start off quickly on slopes. Do not hold
the vehicle on a hill by pressing the accel-
erator, but apply the handbrake instead. Other-
wise overheating can occur in the transmission
region.<
Gear changes
Using selector lever
>To upshift, pull the selector lever back.
>To downshift, push the selector lever for-
ward.
Using shift paddles on steering wheel
>To upshift, pull one of the shift paddles.
>To downshift, press.
Dynamic Driving Control
The Dynamic Driving Control makes it possible
for your BMW to react in an even more perfor-
mance-oriented manner at the push of a button:
>The engine responds more spontaneously
to accelerator pedal movements.
>Gearshifts are faster.
>The engine speed range is used optimally in
the Drive mode.
>Cruise control
*:
The stored speed is reached more quickly
when it is requested.

back, the manual mode is activated and the
Steptronic shifts the gear. The instrument clus-
ter shows M1 through M6.
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. The
selected gear is briefly displayed in the instru-
ment cluster, followed by the current gear.
To use the automatic function again, move the
selector lever to the right into position D.

Cruise control*
The concept
The cruise control is available for use at speeds
of approx. 20 mph/30 km/h and higher. The
vehicle stores and maintains the speed that you
set using the lever mounted on the steering col-
umn.
Do not use the cruise control under driv-
ing conditions that do not permit a con-
stant speed, e.g. when driving on winding
roads , in heavy traffic o r in poor roa d co nditions
such as snow, rain, ice, and loose road surface.
Otherwise you could loose control of the vehi-
cle and cause an accident.<
