system, the alarm will sound
2. Turn the ignition key to position 1:
The time display will count down for
the next ten minutes
3. After ten minutes, start the engine.
If the code becomes available

Park Distance Control (PDC)
*
ASC+T/DSC
*
PDC does not remove the driver's
personal responsibility for evalu-
ating the distance between the vehicle
and any obstacles. Even with the sen-
sors, there is a blind spot in which
objects cannot be detected. This
applies especially in those cases where
the system approaches the physical
limits of ultrasonic measurement, as
occurs with tow bars and trailer cou-
plings, and in the vicinity of thin or
wedge-shaped 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 4 in (10 cm).<
Automatic Stability Control plus
Traction (ASC+T)/Dynamic
Stability Control (DSC)
*
These systems contribute to additional
vehicle stability, especially during
acceleration and when cornering.
The DSC system enhances the benefits
of the ASC+T. In addition to optimizing
vehicle stability and traction during
acceleration or when starting from a
standstill, a further benefit is realized in
cornering. This, of course, is true only
within physically feasible limits.
The system activates automatically
each time you start the engine.

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.

"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.<

area operates the same way.390de638
The reading lamps are located in the
front near the interior lamp. There are
also reading lamps in the rear. They can
be switched on and off with the button
(arrow) adjacent to each lamp.
To avoid subjecting the battery to
excessive loads, all of the lamps
within the vehicle are automatically
switched off approx. 15 minutes after
you turn the ignition key to position 0.< 394de301
