The conceptThe PDC assists you when you are
parking. A signal warns you of the real
distance to an obstacle. To do this, four
ultrasonic sensors in the front and rear
bumpers measure the distance to the
nearest object. The monitoring range
for the front and both rear corner sen-
sors extends approx. 2 ft (60 cm) be-
yond the bumper. The range for the
center rear sensors extends approx. 5 ft
(1.50 meters).Automatic operationThe system starts to operate automati-
cally approx. one second after you se-
lect reverse or move the selector lever
into the "R" position with the ignition
key in position 2.
Turn on manuallyPress the button (arrow), the indicator
lamp comes on.
After driving more than approx. 160 ft
(50 meters) or exceeding approx.
20 mph (30 km/h), the system switches
off and has to be switched back on
when you want to use it again.390us713
Acoustic signalsThe distance to an object is indicated
by a high beeping sound in the front
and a low beeping sound in the back.
As the distance between vehicle and
object decreases, the intervals between
the tones become shorter. A continu-
ous tone indicates the presence of an
object less than 1 ft (30 cm) away.
The warning signal will be canceled af-
ter approx. 3 seconds if the distance to
the obstruction remains constant during
this time (if you are moving parallel to a
wall, for instance).
Malfunction in the PDC system:
The indicator lamp flashes and a brief
continuous signal tone is heard
>when the PDC system is actived via
the button
>when you first select reverse or move
the selector lever into the "R" posi-
tion after switching on the ignition
>when there is a malfunction while the
PDC system is active.
Switch the system off and have the
cause of the malfunction corrected by
your BMW center.

To reactivate the systemPress the button again; the indicator
lamp goes out.
The laws of physics cannot be
repealed, even with ASC+T/DSC.
An appropriate driving style always
remains 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
ASC+T/DSC, please refer to the
chapter describing "Advanced
technology" on page 207.
The concept 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 system to "learn" the
correct tire inflation pressure, check the
inflation pressure in all tires. Refer to
the table of "Tire inflation pressures"
beginning on page 29 and make any
necessary corrections. Then activate
the system.
This indicator lamp in the in-
strument cluster or the Check
Control will inform you if the
tire pressure is not correct.
Activate the system1 Turn the ignition key to position 2 (do
not start the engine).
2 Press and hold the button (arrow) un-
til the yellow indicator lamp in the in-
strument cluster comes on for a few
seconds or the message "SET TIRE
PRESSURE" appears in the Check
Control.
3 After you have driven for a few min-
utes, the RDC will import the current
inflation pressure in the tires as the
target values which the system will
monitor.
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.390de320

Interior lamps Reading lampsFootwell lamps The footwell lamps operate in the same
way as the interior lamps.
The reading lamps are located in the
front near the interior lamp. There are
also reading lamps in the rear. They can
