Onboard computer Range The computer bases its calculations
of the cruising range on the rate of fuel
consumption in the period immediately
preceding your data request.462us024
Average speed If you continue to hold the button, the
average speed last displayed is recal-
culated from that point in time.
Any time spent when the vehicle is sta-
tionary and the engine is shut off is
ignored for the calculation.462us025

The PDC assists you when you back
into a parking space. A signal warns
you of the distance to an obstacle. To
do this, four ultrasonic sensors in the
rear bumper measure the distance to
the nearest object. The monitoring
range of the two corner sensors ex-
tends to approx. 2 feet (60 cm) behind
the bumper. The two center sensors
cover a distance of approx. 4.9 feet
(1.50 meters).
The system starts to operate automati-
cally about one second after you se-
lect reverse with the ignition key in po-
sition 2. PDC is deactivated when you
shift back out of reverse.
Acoustical signalsThe distance to the nearest object is in-
dicated 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 warning tone sounds if the
distance to a recognized object is less
than 1 foot (30 cm).
The warning signal is canceled after
approx. three seconds if the distance to
the obstacle 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.The PDC does not remove the
driver's personal responsibility for
evaluating the distance between the
vehicle and any obstacles. Even when
sensors are involved, there is a blind
spot in which objects cannot be de-
tected. This applies especially in those
cases where the system approaches
the physical limits of ultrasonic mea-
surement, as occurs with tow bars and
trailer couplings, and in the vicinity of
thin and painted objects.
Certain sources of sound, such as a
loud radio, could drown out the PDC
signal tone.<
Keep the sensors clean and free
of ice or snow in order to ensure
that they continue to operate effec-
tively.
Do not apply high-pressure spray to the
sensors for a prolonged period of time.
Maintain an adequate distance of more
than approx. 4 inches (10 cm).<

DSC Dynamic Stability Control (DSC) This system provides enhanced driving
stability, especially when you are just
starting off or accelerating, and provide
increased traction on curves.
In addition to optimizing road traction
and vehicle stability when the vehicle is
accelerating or starting, the system also
provides enhanced stability when cor-
nering within physically feasible limits.
The system starts up automatically
each time you start the engine.462us026
Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition.
Refer to pages 21 and 22.
Indicator lamp flashes:
The system is actively regulating drive
torque in response to monitored vehicle
operating conditions.
If the indicator lamp fails to go out after
the engine is started, or comes on dur-
ing the course of normal vehicle opera-
tion:
If the system has not been deactivated,
there is a system malfunction. The vehi-
cle remains operational, but without
DSC.
Please consult your authorized BMW
center for repairs.
To deactivate the systemPress the button. The indicator lamp
will come on.
The illustration depicts the arrangement
of the buttons if the vehicle is fully
equipped. This may vary, depending on
the equipment actually installed.
When the DSC is deactivated, you are
operating with conventional torque
transfer.
In exceptional instances, it is effective
to deactivate the system:
>when rocking the vehicle or starting
off in deep snow or on loose surfaces
>or when driving with snow chains.
Refer also to page 110.To reactivate the systemPress the button again; the indicator
lamp goes out.
The laws of physics cannot be re-
pealed, even with DSC. Any con-
sequences arising from traction loss
due to excessive vehicle speed remain
the responsibility of the driver. We
therefore urge you to avoid using the
additional safety margin of the system
as an excuse for taking risks.<
For additional details concerning DSC,
please refer to the chapter "Advanced
technology" on page 161.

Tire Pressure Control (RDC)
*
The conceptThe RDC monitors the tire pressures at
all four wheels, even when the vehicle is
moving. The system provides an alert
whenever the inflation pressure drops
significantly below the specified pres-
sure in one or more tires.
In order for the RDC to "learn" the cor-
rect tire inflation pressure, first check
the tire inflation pressure in all tires.
Then compare these pressures with the
tire inflation pressure chart (page 28)
and adjust if necessary. Then activate
the system.
This indicator lamp in the instru-
ment cluster informs you when-
ever the tire pressure is not nor-
mal.
Activate the system1 Turn ignition key to position 2
2 Press the switch long enough for the
indicator lamp in the instrument clus-
ter to light up yellow for a few seconds
3 After a few minutes of driving, the
RDC sets the current inflation pres-
sure in the tires as the target value to
be monitored.
You will only have to repeat this proce-
dure if the tire inflation pressure must
be corrected. Otherwise, the RDC func-
tions automatically when the ignition
key is in position 2, and thus operates
whenever the vehicle is driven.462de228
Loss of tire pressureIf the inflation pressure has dropped too
much over a period of time (which is
normal for any tire), the indicator lamp
will come on with a yellow lamp.
This alerts you to have the tires inflated
to the specified pressures as soon as
possible.
If you are prompted to check the
tire pressure shortly after a cor-
rection has been made, this indicates
that the corrected values were not ac-
curate. Please check the inflation pres-
sure again and make corrections ac-
cording to the inflation pressure table.
Then activate the system once again.<

Flat tireIf there is a tire failure with loss of pres-
sure, the indicator lamp comes on with
a red lamp. In addition, there is an
acoustical warning signal.
If this occurs, reduce vehicle speed im-
mediately and stop the vehicle in a save
location. Avoid hard brake applications.
Do not oversteer. Replace the wheel
and flat tire.
The space-saver spare tire
* is
provided for temporary use only in
the case of a tire failure. It does not
have RDC electronics and is not moni-
tored. A full-size spare tire
* that has the
same dimensions as the tires already
mounted on the vehicle is equipped
with the necessary RDC electronics,
and will also be monitored once the
tires have been mounted and the sys-
tem activated.<
The RDC cannot alert you to
severe and sudden tire damage
caused by external factors.<
Have the tires changed by your
authorized BMW center.
Your authorized BMW center has been
trained to work with the RDC system
and is equipped with the necessary
special tools.<
System interferenceThe RDC can be subjected to interfer-
ence locally by outside equipment or
devices which use the same radio fre-
quency.
The indicator lamp will come on with
a yellow lamp during the malfunction.
The indicator lamp also comes on
>in the event of a system fault
>if a wheel is mounted without the
appropriate electronics
>if, in addition to the spare tire
*, addi-
tional wheels with RDC electronics
are on board.
Please contact your authorized BMW
center for additional information.

Parking lamps
With the switch in this position,
vehicle lighting is illuminated on
both sides. For lighting on one
side for parking, see page 85.
Low beam headlamps
When you switch the ignition off
with the low beam headlamps
on, only the parking lamps will
remain on.
"Follow-Me-Home" lamps:
If you activate the headlamp
flasher after parking the car, then the
low-beam headlamps will come on for a
short time. You can also have this func-
tion deactivated.<

LAMPS ON warningWhen you open the driver's door after
turning the ignition key to position 0, a
warning signal sounds for a few sec-
onds to remind you that the headlamps
have not been switched off
.
Daytime-driving lamps

If desired, the lamp switch can be left in
the second position: When the ignition

also switched off.
Turn the rotary dial to adjust the illumi-

Reading lamps

The reading lamps are located in the
front near the interior lamp and in the
rear of the vehicle (illustration). They
can be switched on and off with the
switch adjacent to each lamp.
In order to keep the battery from
draining, all of the lamps in the
vehicle are switched off automatically
approx. 15 minutes after the ignition
key is turned to position 0.< 460de155
