>The hazard warning flashers for approx.
five minutes
>The high beams, which flash on and off
in the same rhythm.To arm and disarm the alarm system When you lock (or unlock) the vehicle,
either with the remote control unit or at the
door lock, the alarm system is armed (or
disarmed) at the same time.
The system indicates that is has been
correctly armed by switching on the hazard
warning flashers for a single cycle and by
emitting an acoustic signal.
You can have different acknowledg-
ment signals set to confirm arming
and disarming.<
Even with the alarm system armed, you can
open the luggage compartment lid using
the button 3on the remote control
unit, refer to page 36. The alarm system will
start to monitor the luggage compartment
lid again as soon as it is reclosed. Indicator lamp displays>The indicator lamp below the interior
rearview mirror flashes continuously: the
system is armed
>The indicator lamp flashes when the
system is armed: door(s), the hood or
luggage compartment lid are not
completely closed. Even if you do not close
the alerted area, the system begins to
monitor the remaining areas, and the indi-
cator lamp flashes continuously after
10 seconds. However, the interior motion
sensor is not activated >If the indicator lamp goes out when the
system is disarmed: no manipulation or
attempted intrusions have been detected in
the period since the system was armed
>If the indicator lamp flashes for roughly
5 minutes when you disarm the system, or
until the remote control unit is inserted in
the ignition lock: an attempted entry has
been detected in the period since the
system was armed.
Following triggering of an alarm, the indi-
cator lamp will flash continuously.
Avoiding unintentional alarms The tilt alarm sensor and interior motion
sensor may be switched off at the same
time. You can do this to prevent a false
alarm from being triggered (in garages with
elevator ramps, for instance), or when the
vehicle is transported by trailer or train:
Lock the vehicle, i. e., arm the alarm system
twice in a row by pressing button 2 on the
remote control unit twice in succession,
refer to page 36, or lock the vehicle twice
using the key, refer to page 37.
The indicator lamp flashes briefly and then
flashes continuously. The tilt alarm sensor
and the interior motion sensor are switched
off long as the system is armed.
If you desire, the

>tilt alarm sensor, and
>interior motion sensor
can be switched off permanently. Please
contact your BMW center for assistance.< Interior motion sensor In order for the interior motion sensor to
function properly, the windows and sliding/
tilt sunroof must be completely closed.
Be sure to deactivate the interior motion
sensor, see section on Avoiding uninten-
tional alarms, when you wish to leave the
windows or sliding/tilt sunroof open.

vehicle could start to roll if parked on a
steep slope.< To re-engage the lockout 1.Disengage the release lever by pressing
it together with the red detent lever,
arrow 1
2.Guide the release lever all the way back
into its original position Ð the transmission
lockout is again engaged
3.Fold up and lock the cover panel. Now Ð
and not before Ð the key may be removed.
Once the transmission lockout has
been re-engaged, the warning in the
Check Control should disappear, and the
symbol in the Info Display should change
from N to P. Should this fail to happen,
there is a danger that the vehicle could
start to roll.<
Information on jump-starting, tow-starting
and towing begins on page 187. Turn signal indicators/
headlamp flasher1High beams Ð blue indicator lamp
2Headlamp flasher Ð blue indicator lamp 3Turn signal indicators Ð the green indi-
cator lamp flashes, accompanied by a peri-
odic ticking from the turn signal indicator
relay.
To use the turn signal indicatorsMove the lever beyond the detent position.
It then returns to the center position when
released. Press the lever as far as the
detent to switch off the turn signals. To signal brieflyPress the lever up to but not beyond the
detent. It then returns to the center position
when released.
If the flashing of the indicator lamp and the
ticking from the relay are both faster than
normal, this indicates that one of the bulbs
is defective; if a trailer is attached, this
could also indicate that one of its turn
signal indicator bulbs is defective. Wiper system1Standard wiper speed: press briefly one
time.
Fast wipe: briefly press twice

You also enjoy the option of having the
system show distances to objects in the
Control Display. The Control Display will
also indicate the presence of objects in
green before they are close enough to
generate a signal tone.
Select "PDC pic." from the "Settings" menu
and confirm your selection. This activates
the PDC display.
The display then appears in the Control
Display whenever PDC is automatically or
manually activated.
The previous display automatically reap-
pears after the system is deactivated.
Confirm in the menu to return to
the previous display.<
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always
remains with the driver. Even when sensors
are involved, there is a blind spot in which
objects cannot be detected. The system is
also subject to the physical limits that apply
to all forms of ultrasonic measurement,
such as those encountered with tow bars
and trailer couplings, as well as thin and
wedge-shaped objects, etc. After initial
detection, low objects such as curbs, etc.,
may disappear again before the system
starts to generate a continuous warning
tone. Loud noises from outside and inside
the vehicle may prevent you from hearing
PDC's signal tone.<
Keep the sensors clean and free of ice
or snow in order to ensure that they
will continue to operate effectively.
Do not apply high pressure spray to the
sensors for a prolonged period of time. Keep the spray at least 4 in (10 cm) away
from the sensors.<
Driving stability control/
DSC Dynamic Stability
Control Your BMW is equipped with an extended
array of systems designed to enhance and
maintain vehicle stability under extreme
conditions. The following section describes
these functions based on DSC and ABS. The concept DSC 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.
The system recognizes any tendency for
the vehicle to assume an unstable attitude
such as oversteer or understeer; it then
counteracts this tendency with a combina-
tion of graduated reductions in engine
torque and selective braking intervention at
individual wheels. DSC provides optimal
stability within the limits defined by the
laws of physics.
The DSC is operational every time you start
the engine. DSC includes the functionality
of the DTC Dynamic Traction Control and
DBC Dynamic Brake Control.
With its selective braking intervention at the
individual drive wheels, DTC fulfills the
same function as a conventional limited-
slip differential to enhance traction under
difficult driving conditions, such as on
snow, etc. Indicator lamps
The indicator lamp in the Info
Display goes out soon after you
start the engine.
If the indicator lamp flashes:
DSC controls the drive and braking forces.
The indicator lamp stays lit:
DSC has been switched off via the Control
Display.

Replacing components
184 the jack could slip to the side if you attempt
to raise the vehicle on a soft or slippery
surface such as snow, ice, tiles, etc.
Position the jack on a firm support surface.
Do not use a wooden block or similar
object as a support base for the jack, as
this would prevent it from extending to its
full support height and reduce its load-
carrying capacity .
To avoid serious or fatal injury: never lie
under the vehicle, and never start the
engine while it is supported by the jack.<
What you will need To avoid rattling noises, note the positions
of the tools before removing them, then
return them to their initial positions after
completing work.
