Speed limitSpeed limit entry:
You can enter the road speed at which
you wish to hear and see a reminder
signal: a signal will sound, the word
LIMIT will flash, and for a moment, the
speed limit warning stored in the
memory will appear on the instrument
cluster as an alphanumeric display
*,
along with the Check Control.
The speed limit reminder is only
repeated if the vehicle has in the
meantime been driven at least 3 mph
(approx. 5 km/h) slower.

The conceptPDC provides extra safety and conve-
nience during parking maneuvers by
providing an acoustic signal to indicate
the distance between your front and
rear bumpers and the nearest object.
To do this, four ultrasonic sensors in
the front and rear bumpers each mea-
sure the distance to the nearest object.
The monitoring range of the front sen-
sors and two rear sensors at the ends
of the rear bumper extends outward
roughly 2 ft (60 cm), while the rear
bumper's two centrally located sensors
detect objects at distances of up to
approx. 5 ft (1.50 meters).Automatic functionThe system starts to operate automati-
cally approx. one second after you
select reverse or move the selector
lever into the "R" position with the igni-
tion key in position 2.
Manual activationPress the button, the indicator lamp
lights up.
When you subsequently drive a dis-
tance of more than approx. 160 ft
(50 meters) or exceed a speed of
approx. 20 mph (30 km/h), the system
switches off and the indicator lamp
goes out. Reactivate the system as
required.390us727
Acoustic signalsThe distance from an obstacle is indi-
cated in front with a higher intermittent
tone, at the rear with a lower intermit-
tent tone. As the distance between
vehicle and object decreases, the inter-
vals between the tones become
shorter. A continuous tone indicates the
presence of an object less than 1 ft
(30 cm) away.
The warning signal is canceled after
approx. three seconds if you are
moving parallel to a wall.
If there is a malfunction of the system:
The indicator lamp flashes and a brief
continuous signal tone is heard
>if you activate PDC with the button
>when you first select reverse or move
the selector lever into the "R" posi-
tion after switching on the ignition
>if a malfunction occurs while the PDC
system is active.
Switch the system off and have the
cause of the malfunction corrected at
your BMW center.

Self-leveling suspension
*
Tire Pressure Monitor (RDC)
*
The warning lamp for the self-
leveling suspension comes on,
or the message "SELFLEVEL
SUSP.INACT" appears in the Check
Control: there is a malfunction in the
self-leveling suspension.
Stop and inspect the vehicle. If it is
riding significantly lower in the rear than
in the front, or if it is sitting at an incline
(left rear compared to right rear), con-
sult the nearest BMW center. Drive with
appropriate caution in the meantime.
The vehicle has reduced ground clear-
ance or driving comfort is noticeably
reduced.
Even if the attitude of the vehicle is
normal, you should consult the nearest
BMW center if the warning lamp indi-
cates a system fault.
The conceptRDC 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 27 and make any
necessary corrections. Then activate
the system.
This indicator lamp in the instru-
ment cluster or the Check Con-
trol 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. Maintain pressure on the button until
the yellow indicator lamp in the
instrument cluster comes on for sev-
eral seconds or the message "SET
TIRE PRESSURE" appears in the
Check Control panel
3. After you have driven for a few min-
utes, the RDC will import the current
inflation pressure in the tires as the
reference 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.390de704

Parking lamps (side marker
lamps)
With the switch in this position,
the front, rear and side vehicle
lighting is switched on.
For lighting on one side for parking as
an additional feature, refer to page 104.
Low beams
When the ignition is switched off
while the low beams are on, the
headlamps go out and only the
parking lamps (side marker lamps)
remain on.
390de732
"Follow me home":
When you activate the headlamp
flasher after parking the vehicle and
switching off the lamps, the low beams
will come on for a brief period. You may
also have this function deactivated if
you wish.<
"LIGHTS ON" warningWhen the driver's door is opened with
the ignition key in position 0 an acoustic
signal will sound for several seconds to
remind you that you have forgotten to
switch off the lamps
.
Vehicles with alphanumeric Check
Control
*:
The reminder is provided by the Check
Control, refer to page 87.
Daytime driving lamps
*
The headlamps are automatically
switched on for daytime driving in
ignition key position 2.
Automatic headlamp control
*
When the switch is set to this
position the system automati-
cally activates and cancels the
low beams in response to changes in
ambient light ( in tunnels, at dusk, etc.)
as well as rain and snow.
The vehicle's external lamps
remain on constantly when you
switch on the front fog lamps after the
headlamps have come on automati-
cally.<
Automatic headlamp control
cannot serve as a substitute for
the driver's judgement in determining
when the vehicle lamps should be
switched on. For example, the sensors
are not able to detect fog. To avoid
safety risks, you should respond to
these kinds of low-visibility situations
by switching the headlamps on manu-
ally.<
You can have the sensitivity of
your vehicle's automatic head-
lamp control adjusted.<

Cargo area Ð sport wagonFold the rear backrests downReach into the recess and pull upward
(arrow).
The rear backrest is divided into two
sections (one-third and two-thirds of
the width of the seat). You can fold
either section of the backrest down
separately in order to increase the
capacity of the cargo area.
When you close the backrest, be
sure that the catch engages
securely. The red warning indicator dis-
appears in the recess when the retainer
is locked.
The center safety belt can be retracted
only when the larger backrest is
engaged.<392de753
Roll-up coverPull the roll-up cover out and hook it
into the rear bracket.
The cover will support light objects
such as items of clothing.
Do not place heavy or bulky
objects on the roll-up cover,
otherwise, they could endanger occu-
pants while braking hard, during eva-
sive maneuvers, or in an accident, for
example.
Do not allow the cover to snap back,
since this could damage it.<
For storing the case, refer to the next
page.392de754
Partition netPull out the partition net by the strap
and hold the bar firmly in the other
hand. Then grasp the bar on both sides,
pull it up and engage it in the holders. It
is easiest to do this from the back seat.
Do not allow the partition net to
snap back. Doing so could pose a
risk of injury and the partition net could
be damaged.<
When the rear backrests are folded
down, you can store the case in front of
the rear seats, pull the partition net out
from there and insert it in the front
holders (refer to the next page).392de163
