Indicator and warning lamps
Technology that monitors itself
Indicator and warning lamps that are identified
by
+ are tested for proper functioning whenever
the ignition key is turned. They each light up
once for different periods of time.
If a malfunction occurs in one of the monitored
systems, the corresponding light does not go
out after the engine has started, or it lights up
again while the vehicle is in motion. You can find
more information about each system on the
specified pages.

completely closed. Even if you do not close
the area causing the alert, the remaining
areas are secured and the indicator lamp
flashes continuously after 10 seconds.
However, the interior motion sensor is not
activated
>If the indicator lamp goes out immediately
after the vehicle is unlocked:
No manipulation or attempted intrusions
have been detected in the period since the
system was armed
>If the indicator lamp flashes for 10 seconds
immediately after the vehicle is unlocked:
An attempted entry has been detected in
the period since the system was armed.
After an alarm has been triggered, the indicator
lamp will flash continuously.
Tilt alarm sensor and interior motion
sensor
Tilt alarm sensor
The inclination of the vehicle is monitored. The
alarm system reacts, e.g. to attempts to steal
the wheels or tow the vehicle.
Interior motion sensor*
The system monitors the footwells and the
seating areas of the driver and passenger. Even
when the convertible top is open, the alarm sys-
tem including the interior motion sensor is
armed. Objects falling into the vehicle, e.g.
leaves, can trigger unintentional alarms, refer to
Avoiding unintentional alarms.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion sensor
can be deactivated at the same time. In this way
you can avoid unintentional alarms, e.g. in the
following situations:
>In duplex garages
>When the vehicle is being transported on a
car-carrying train
>If animals are to be left in the vehicle.
To deactivate the tilt alarm and interior
motion sensors
Press the button on the remote control
a second time immediately after locking.
The indicator lamp lights up briefly and then
flashes continuously. The tilt alarm sensor and
the interior motion sensor are deactivated until
the vehicle is again unlocked and locked.

Adjustments

and makes adjustments accordingly.
Colored decals were provided with the keys to
help you distinguish between the different per-
sonal remote control keys.
What the system can do
You can learn about the entire array of features
that Vehicle Memory and Key Memory offer you
at your BMW center. A few examples follow
below:
Examples for Vehicle Memory:
>Various signals as acknowledgement when
locking or unlocking your vehicle: refer to
page17
>Windows are opened automatically, refer to
page20
>Reminder that the key is still in the ignition
switch after the driver's door has been
opened, refer to page37
>Activation/deactivation of the Follow-me-
home function: refer to page56
>Activation/deactivation of daytime driving
lamps: refer to page56
>Sets the units of measure for displaying
time, outside temperature, distance trav-
eled and fuel consumption in the instru-
ment cluster, refer to page48.
Examples for Key Memory:
>Locking of the vehicle when you start off:
refer to page18

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
the selector lever to the right toward D.

rupted when you approach this sector.
Fuel gauge
When indicator lamp1 begins to stay on contin-
uously, there are still approx. 2.1 gallons/8 liters
of fuel in the fuel tank.
Tank capacity: approx. 14.5 gallons/55 liters.
If the tilt of the vehicle varies, for example when
you are driving in mountainous areas, the nee-
dle may fluctuate slightly.
Fill the fuel tank well before it is empty.
Driving to the last drop of fuel can prevent
the engine from operating properly and result in
damage.<
