Rollover protection system In the event of an accident or some
other critical driving situation – extreme
tilting in the longitudinal or transverse
axis, loss of contact with the ground –
the rollover protection system will be
automatically activated. The protective
bars located in the rear head restraints
extend within fractions of a second.
In addition to the integrated rollover bar
in the windshield frame, the rollover
protection system affords all the vehicle
occupants necessary headroom.
Always keep the travel path for the
rollover protection system free
and clear. Under no circumstances
should you cover the head restraints.
In the event of less serious accidents,
the safety belt will protect you and,
depending on the severity of the acci-
dent, so will the safety belt tensioner
and the multi-stage airbag restraint sys-
tem as well.<
If, after being automatically triggered,
the protective function is not needed,
then the rollover protection system can
be lowered back into place. No special
tool is needed for this.
1. Using a screwdriver from the
onboard tool kit, remove the cover
panel; to do this, position the screw-
driver under the notch
2. Push the lever toward the front of the
vehicle and keep it in this position

Shifting gears with shift paddles on
steering wheel:
>To upshift, briefly pull the right pad-
dle +
>To downshift, briefly pull the left pad-
dle –.
Shift paddles with various widths
matched to the shape of your
hand are available from your BMW cen-
ter.<
Shifting gears with selector lever:
>To upshift, pull the selector lever
backward in the '+' direction
>To downshift, push the selector lever
in the '–' direction.
No automatic upshifting is carried out in
the sequential mode.
You accelerate from higher gears, e.g.
during passing, by manually downshift-
ing.
In the following situations the
SMG Drivelogic anticipates your
actions in the sequential mode:
>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 are
not executed
>During a stop the gearbox is auto-
matically downshifted into the first
gear so that, e.g. before a traffic light,
it is only necessary to accelerate to
continue driving
>As speed diminishes, the gearbox
downshifts automatically, without you
taking any action, just before the
vehicle slows to below each gear's
minimum speed.D - Automated modeEach time the engine is started, the
automated mode is activated as soon
as you move the selector lever into the
forward driving position.
In the automated mode all forward
gears are shifted automatically.To switch from sequential to automated
mode: tap the selector lever to the right
toward 'D'. Watch the display in the
instrument cluster, refer to page 71.
For rapid acceleration, e.g. during
passing, depress the accelerator pedal
completely – kickdown. The gearbox
now downshifts depending on the
selected driving program.
Even in the automated mode, you can
help specify the shifting point: if a gear-
dependent minimum speed is
exceeded, you can upshift by slowly
reducing pressure on the accelerator
pedal. In the process, the respective
driving situation is detected by sensors
and taken into account.

85 Technology 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. To do this,
four ultrasonic sensors in the rear
bumper measure the distance to the
nearest object. The range for the sen-
sors located at both rear corners ends
approx. 2 ft/60 cm behind the bumpers.
The range for the two middle sensors is
slightly less than 5 ft/1.50 m.
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 your BMW center
resolve the problem.
PDC does not remove 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.<

Tips for pleasant drivingUse the automatic mode – switch on
with AUTO button 6. Select the desired
interior temperature.
Detailed setting options are described
for you in the following sections.
You can make the settings of your
vehicle in such a manner that,
when you unlock the vehicle with the
remote control of your personal key,
your own personalized setting for the
automatic climate control is initiated. supply
The AUTO program adjusts the
air distribution and the air sup-
ply for you and in addition adapts the
temperature to external influences –
summer, winter – to meet preferences
you can specify.
Individual air distribution
You can cancel the AUTO pro-
gram by selecting specific dis-
tribution patterns to suit your
own individual requirements.
While the AUTO program is then deacti-
vated, the automatic airflow control
remains in operation. Air flows onto
the windows , toward the upper
body , and into the footwell . You
can reactivate the automatic air supply
by pressing the AUTO button.Temperature
The interior temperature that
appears in the display panel is a
general figure intended for refer-
ence purposes. We recommend
727/+226 as a comfortable setting,
even if the air conditioning is on. When
you start the vehicle, the system
ensures that the selected temperature
is reached as quickly as possible. It
then maintains this temperature,
regardless of the season.
To select the units of measure 6/7
of the display, refer to page 83.
Air supply/Blower
By pressing the upper or lower
button, you can vary the air sup-
ply. This deactivates the auto-
matic air supply – the AUTO display dis-
appears from the panel. Nevertheless,
the automatic air distribution remains
unchanged. You can reactivate the
automatic air supply by pressing the
AUTO button.
When the lowest blower speed is set
and you press the lower button, all of
the displays are canceled: the blower,
heating and air conditioner are
switched off, and the air supply is
stopped. You can reactivate the system
by pressing any button for the auto-
matic climate control.To defrost windows and remove
condensation
This program quickly removes
ice and condensation from the
windshield and the side windows.
Air conditioning
The air is cooled and dehumidi-
fied and – depending on the
temperature setting – rewarmed.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started. Air conditioning helps
prevent the windows from fogging up.
Condensation forms during opera-
tion of the air conditioning system,
which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
