Floor matYou can turn the floor mat over to trans-
port soiled objects, etc. The rubber-
coated side is suitable for washing and
is also designed to inhibit sliding.
The fittings at the corners of the lug-
gage compartment provide you with a
convenient means of attaching luggage
compartment nets* and flexible straps
for securing luggage.
Refer also to Cargo loading on
page 106.
Alarm system*The conceptThe vehicle alarm system responds:
>When a door, the hood or the lug-
gage compartment lid is opened
>To movement inside the vehicle –
interior motion sensor
>To variations in the vehicle's tilt angle
such as those occurring during
attempts to steal the wheels or tow
the vehicle – tilt alarm sensor.
>To interruption of battery voltage.
The system responds to unauthorized
vehicle entry and attempted theft by
simultaneously activating the following:
>The acoustic alarm sounds for
30 seconds
>The hazard warning flashers are acti-
vated for approx. five minutes
>The high beams flash on and off in
rhythm with the hazard warning flash-
ers.To arm and disarm the alarm
systemWhen the vehicle is locked or unlocked
via the remote control or the driver's
door lock, the alarm system is also
simultaneously armed or disarmed.You can have different acknowl-
edgment signals set to confirm
arming and disarming.<
You can also open the luggage com-
partment lid when the system is armed
by pressing the remote control button,
refer to page 30. The lid is once again
secured when it is closed.
Extended pressure on the button sets
off the alarm – Panic mode, refer to
page 30.

Indicator lamp displays>The indicator lamp below the interior
rearview mirror flashes continuously:
the system is armed
>The indicator lamp flashes immedi-
ately after the vehicle is locked: doors
or luggage compartment lid are not
completely closed. Even if you do not
close the alerted area(s), the remain-
ing areas are secured, and the indi-
cator lamp will flash continuously
after 10 seconds. However, the inte-
rior motion sensor is not activated
>The indicator lamp goes out immedi-
ately after the vehicle is unlocked: no
manipulation or attempted intrusions
have been detected in the period
since the system was armed
>The indicator lamp flashes for
10 seconds immediately after the
system is armed: an attempted entry
has been detected in the period since
the system was armed.
Following triggering of an alarm, the
indicator lamp will flash continuously.Tilt alarm sensor and interior
motion sensorTilt alarm sensor:
The tilt of the vehicle is monitored. The
alarm system reacts, for example, to
attempts to steal the wheels or tow the
vehicle
Interior motion sensor:
In order for the interior motion sensor to
function properly, the windows and the
glass sunroof must be completely
closed.Avoiding unintentional alarmsThe tilt alarm sensor and interior motion
sensor may be switched off at the same
time. You can do this to prevent a false
alarm, e.g. in the following situations:
>In garages with elevator ramps
>When the vehicle is being trans-
ported by train
>When animals are to remain in the
vehicle.
To deactivate the tilt alarm and
interior motion sensors>Press the button on the remote con-
trol twice.
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
unlocked and locked again.
You can have the tilt alarm sensor
and the interior motion sensor
permanently deactivated.<
The system inadvertently deacti-
vates the tilt alarm sensor and the
interior motion sensor if the conve-
nience closing of windows and glass
sunroof is interrupted within the first
10 seconds and then restarted. The
vehicle must then be unlocked and
relocked before the sensors will resume
operation.<

engine, refer to Starting the engine on
page 60.Sequential modeEach time the engine is started, the
sequential mode is activated as soon as
you move the selector lever into the for-
ward driving position while the brake is
depressed.
The gears are shifted via the shift pad-
dles or the selector lever.
It is also possible to drive off in second
gear, e.g. on snow-covered roads.DDrive modeIn 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.
For rapid acceleration, e.g. during
passing, depress the accelerator pedal
completely: kickdown.To switch back to sequential mode: tap
the selector lever again to the right
toward D or change the current gear via
the shift paddles or the selector lever.
KickdownYou can achieve maximum acceleration
using kickdown.
Depress the accelerator pedal past the
increased resistance point at the full-
throttle position.
Shifting gearsWith the selector lever:
>To upshift, tap the selector lever
toward +
>To downshift, tap the lever toward —.
With the shift paddles on the steering
wheel:
>To upshift, pull one of the shift pad-
dles
>To downshift, push the paddle.
You accelerate from higher gears, e.g.
during passing, by manually downshift-
ing.
In the following situations, the SMG in
the sequential mode assists you:
>Upshifts and downshifts are only exe-
cuted at appropriate combinations of
engine rpm and vehicle speed. For

instance, downshifts that would
result in excessive engine speed can-
not be executed
>When you brake the car to a stop, the
transmission automatically shifts
down to first gear
>As speed diminishes, the transmis-
sion will shift down automatically,
without any action on your part, just
before the vehicle slows to below
each gear's minimum speed.

Automatic transmission with Steptronic*In addition to the fully automatic opera-
tion, you can also shift gears manually
with Steptronic, refer to page 68.
When you move the selector lever from
the D position to the left into the M/S
range, the performance-oriented shift
programs of the automatic transmission
are engaged. Steptronic enters the
manual selection mode and executes
the desired shift whenever you tap the
selector lever in the direction indicated
by + or –. Whenever you want to use
the automatic mode again, just shift the
selector lever toward the right to posi-
tion D.
Under normal operating conditions, fuel
consumption is lowest when driving in
position D.Selector lever positionsP R N D M/S + –Starting the engineThe engine can only be started in selec-
tor lever positions P – for Park – or N –
for Neutral.
Range selectionA catch prevents inadvertent movement
of the selector lever to positions R and
P. To deactivate the catch, press the
button on the front of the selector lever
knob, see arrow.
While the vehicle is stationary and
before shifting out of Park or Neu-
tral, depress the footbrake in order to
disengage the selector lever's lock
mechanism – Shiftlock.<
Hold the footbrake down until
starting off. Otherwise the vehicle
will 'creep' when a drive position is
engaged. To prevent the vehicle from
starting off on its own, always move the
selector lever to position P and engage
the parking brake before leaving your
vehicle with the engine running.
Do not leave the vehicle unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a safety hazard.<

KickdownYou can achieve maximum road perfor-
mance using kickdown.
Depress the accelerator pedal past the
increased resistance point at the full-
throttle position.
M/S manual operation and Sport
programWhen you move the selector lever from
the D position to the left into the M/S
range, the sport program is activated,
indicated by the letters SD in the instru-
ment cluster. The M/S mode is recom-
mended for performance-oriented driv-
ing. Steptronic enters the manual
selection mode and executes the
desired shift whenever you tap the
selector lever in the direction indicated
by + or –.
This mode allows you to execute
upshifts manually by tapping the lever
toward +, while downshifts are selected
by tapping in the – direction. The dis-
plays M1 through M5 appear in the
instrument cluster.
The transmission will only execute
upshifts and downshifts that will result
in an appropriate combination of vehi-
cle speed and engine rpm. For
instance, downshifts that would result
in excessive engine speed are not exe-
cuted. The desired, then the actual
gear, briefly appear in the instrument
cluster.
Whenever you want to use the auto-
matic mode again, just shift the selector
lever toward the right to position D.
Shifting from M/S to the selector lever
positions P, R and N is possible only by
going through D.
To accelerate quickly in the man-
ual mode for maneuvers such as
passing another vehicle, shift down
manually or employ the kickdown
mode.<
Shifting from M/S to the selector lever
positions P, R and N is possible only by
going through D.

Wait a few seconds, then start the
engine.
If the indicator lamp goes out after a
few seconds, normal transmission per-
formance has been restored. You may
continue to drive as usual.
If the indicator lamp does not go out,
you can place the selector lever in all
positions. However, the vehicle will now
only operate in 3rd and 4th gear.
If this happens, avoid extreme engine
loads and consult the nearest autho-
rized BMW center.
Never work in the engine com-
partment when a drive gear – for-
ward or reverse – is engaged. If you do
this, the vehicle could move.<

80Technology for safety and driving convenience
Park Distance Control (PDC)*The conceptPDC assists you when you back into a
parking space. Acoustic signals alert
you to the momentary distance to an
object behind your vehicle. For this pur-
pose, four ultrasonic sensors in the rear
bumper measure the distance to the
next object. The monitoring range for
the rear bumper's two corner sensors
extends outward roughly 2 ft/60 cm,
while the two centrally located sensors
detect objects at distances of up to
approx. 5 ft/1.50 meters.
PDC is a parking aid that can
identify objects if they are
approached slowly, as is generally the
case when parking. Avoid driving
towards objects rapidly; due to underly-
ing physical principles, the system may
otherwise alert you too late for you to
take evasive steps.<
The system starts to operate automati-
cally approx. one second after you shift
into Reverse or move the selector lever
into the R position with the ignition key
in position 2.
Let this short period elapse before
driving backwards.<
PDC is deactivated when you shift back
out of Reverse.
You can have a signal set to con-
firm that the PDC has been acti-
vated. The signal then sounds when
you shift into Reverse or move the
selector lever into the R position. indicated by a tone sounding at various
intervals. As the distance between vehi-
cle and object decreases, the intervals
between the tones become shorter. A
continuous tone indicates the pres-
ence of an object less than 1 ft/30 cm
away.
The warning signal is canceled after
approx. three seconds if the distance to
the object remains constant during this
time – if you are moving parallel to
a wall, for instance.
System malfunctions will be indicated
by a continuous high-pitched tone
when the system is activated the first
time. Please have the problem fixed by
your BMW center.
PDC does not replace the driver's
personal responsibility for evaluat-
ing the distance between the vehicle
and any objects. Even when sensors
are involved, there is a blind spot in
which objects cannot be detected. This
applies especially in those cases where
the system approaches the physical
limits of ultrasonic measurement, as
occurs with tow bars and trailer cou-
plings, and in the vicinity of thin or
wedge-shaped objects. Moreover, low
objects that have already been
detected – such as a curb edge – can
disappear out of the detection range of
the sensors before a continuous tone
sounds.
Loud sources of sound from outside or
inside the vehicle could drown out the
PDC signal tone.<
Keep the sensors clean and free
of ice or snow in order to ensure
that they will continue to operate effec-
tively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Always maintain a distance of more
than 4 in/10 cm.<

Adaptive headlights*The conceptAdaptive headlights is a variable head-
lamp control system for dynamically
illuminating the road. Depending on the
steering angle and other factors the
light from the headlamps follows the
course of the road.Activating Adaptive headlights
With the ignition key in position
2, turn the light switch to the
automatic headlamp control
position, refer to page 85. The LED next
to the symbol lights up.
To avoid blinding oncoming traffic,
adaptive headlights are
>not active while reversing,
>active only towards the front passen-
ger side while the vehicle is at a
standstill.
System malfunctionThe LED next to the symbol for auto-
matic headlamp control flashes. The
adaptive headlight system is malfunc-
tioning or out of order. Have the system
checked as soon as possible.
Instrument lightingTurn the rotary dial to adjust the illumi-
nation intensity.
