Alarm systemIndicator lamp displaysThe indicator lamp is located in the
inside rear view mirror's rotary knob.
>The indicator lamp flashes continu-
ously: the system is armed
>The indicator lamp flashes during
arming: a door, the hood or luggage
compartment lid is not completely
closed. Even if you do not respond by
securing the affected area, the system
starts to monitor all other points and
the indicator lamp reverts to contin-
uous, uninterrupted operation once
ten seconds have elapsed. The inte-
rior motion sensor remains off
>The indicator lamp goes out during
disarming: no manipulation or
attempted intrusions have been
detected in the period since the
system was armed520de014
>The indicator lamp flashes for
10 seconds when the system is
disarmed: 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.Avoiding unintentional alarms The tilt alarm sensor and interior motion
sensor may be switched off at the same
time 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 twice (= arm the
system) by pressing button 2 on the
remote control twice in succession
(refer to page 34), or lock the vehicle
twice with the key (refer to page 32).
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor
remain deactivated for as long as the
system is armed.
Interior motion sensorIn order for the interior motion sensor to
function properly, the windows and the
luggage compartment lid must be
closed.
Nevertheless, you should deactivate
the interior motion sensor (refer to the
previous column) if
>children or animals are left in the
vehicle
>windows should remain open.
For US vehicles only:
The interior motion sensor is not
installed on US models as it has not
received FCC (Federal Communica-
tions Commission) approval.<

Dynamic Stability Control (DSC) Dynamic Performance To reactivate the systemPress the button again; the indicator
lamp goes out.
Not even DSC can suspend the
laws of physics. Responsibility for
careless driving remains in the hands
(and feet) of the driver. Never use the
added safety provided by DSC as an
excuse for taking unnecessary risks.
Do not make any modifications to the
DSC system. Service procedures on
the system are to be performed by
authorized technicians only.<
For additional information concerning
DSC, please refer to the chapter
"Advanced technology" on page 151.
The system reacts to current conditions
with an instantaneous recalibration. It
revises the accelerator's standard
response designed to furnish an ideal
combination of comfort and perfor-
mance orientation Ð with a more perfor-
mance-oriented response program. The
result is crisper, faster reaction to
throttle inputs (Sport mode).
The system resets to the standard
response mode, with its combination of
comfort and performance orientation,
each time the engine is restarted. 520de057

Dynamic Performance Flat Tire MonitorSport mode recognitionActivating:
In ignition position 2, press the button.
The indicator lamp will come on.
Deactivating:
Whenever the indicator lamp is on, it
will go out if you press the button again.
The conceptThe Flat Tire Monitor keeps track of the
inflation pressures in all four wheels as
you drive. The system provides an alert
whenever the inflation pressure has
dropped significantly in one of the tires.
To initialize the Flat Tire Monitor with
the correct inflation pressures, start by
ensuring that all of the vehicle's tires
are inflated to the pressures specified
in the inflation pressure table on
page 27. Now you can activate the
system.
The indicator lamp within the
instrument cluster flashes to
alert you to substantial pres-
sure loss in any of the tires.
To activate the system1. Turn the ignition key to position 2
2. Press the button long enough for the
indicator lamp in the instrument
cluster to light up red for a few
seconds
3. As you drive, the Flat Tire Monitor
automatically enters the system
initialization mode in which it stores
the current pressures as its reference
figures. The initialization process
lasts for ten minutes or somewhat
longer. Once it has been completed
the Flat Tire Monitor is able to detect
and warn of flat tires.520de117

Winter operationRubber seals and componentsTo prevent the weather-stripping from
freezing, apply a spray-on rubber treat-
ment or silicone spray to the door, hood
and luggage compartment lid seals.
A full range of car-care products is
available from your BMW center. * only in pairs
on rear tires, complying with the manu-
facturer's safety precautions. Do not
exceed a maximum speed of 30 mph
(50 km/h) while the snow chains are
mounted and refrain from activating the
Flat Tire Monitor, as the snow chains
could trigger false alarms and/or
prevent the system from detecting
actual pressure loss.
Starting off When starting off in deep snow or when
"rocking" the vehicle to free it, it may be
advisable to temporarily deactivate the
DSC. Refer to page 65.
To maintain vehicle stability,
always drive with the system
switched on whenever possible.<
Driving on low-traction road
surfaces Do not activate the Sport mode (refer to
page 66). Use smooth, gentle pressure
to control the accelerator pedal. Avoid
excessive engine speeds and upshift
early. Downshift well in advance when
approaching uphill or downhill grades.
Maintain an adequate distance
between yourself and the vehicle
ahead. BrakesWinter road conditions substantially
reduce the amount of traction available
between the tires and the road surface.
The resulting increases in braking
distance are considerable and should
be kept in mind at all times.
ABS is intended to prevent the wheels
from locking during brake applications,
thus helping to maintain vehicle stability
and steering response. If the ABS does not respond in a critical
braking situation and the wheels lock,
reduce the pressure on the brake pedal
until the wheels just start to roll again
while still maintaining enough force to
continue braking.
Then increase the pressure, reduce the
pressure when the wheels lock, reapply
pressure etc.
This staggered braking procedure will
reduce braking distances while helping
you maintain steering control.
You can always then attempt to steer
around hazards after you have reduced
pressure on the brake pedal.
Never downshift to exploit engine
braking when driving on slippery
road surfaces, as this could lead to a
loss of traction at the rear wheels,
impairing your ability to control the
vehicle.<
Depress the clutch during hard
braking on road surfaces that
provide only poor or uneven traction.<
