When you switch on the ignition, the
indicator lamp lights up briefly as a
function check.
Once the indicator lamp stays on
continuously, there are still approx.
2 gallons (8 liters) of fuel left in the fuel
tank.
For fuel tank capacity, refer to page 187.
If the tilt of the vehicle varies (extended
driving in mountainous areas, for
example), there may be slight fluctua-
tions of the needle.
Please refuel early, since driving
to the last drop of fuel can result
in damage to the engine and/or cata-
lytic converter.<460us081

Remaining distance for serviceThe displays shown in the illustration
appear for a few seconds when the
ignition key is in position 1 or after the
engine is started.
The next service due appears with the
message OIL SERVICE or INSPECTION,
together with the remaining distance
before scheduled service.
The computer bases its calculations
of the remaining distance on the rate of
fuel consumption in the period immedi-
ately preceding your data request.
A flashing display and a "Ð" in front of
the number indicate that service is past
due by the number of kilometers/miles
displayed. Please contact your BMW

ment (6/7) for the outside tempera-
ture display by pressing the right-hand
reset button in the instrument cluster
when the temperature display is active. 460us146
Ice warning If the outside temperature drops to
approx. +37.5 7 (+3 6), the computer
automatically switches to the outside
temperature display. In addition, a
signal sounds as a warning and the
display flashes for a brief period.
The warning is repeated whenever the
temperature climbs to at least +43 7
(+6 6) following the last warning, and
then drops back to +37.5 7 (+3 6).
The ice warning does not alter the
fact that surface ice can form at
temperatures above +37.5 7 (+3 6),
on bridges or shaded road surfaces, for
instance.<

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 rear bumper
measure the distance to the nearest
object. The range for the sensors at the
two rear corners ends approx. 2 ft
(60 cm) from the bumper. The range for
the two center sensors is approx. 4.9 ft
(1.50 meters) wide.
The system starts to operate automati-
cally about one second after you select
"Reverse" with the ignition key in posi-
tion 2. PDC is deactivated when you shift
back out of reverse.
Acoustical signalsThe distance to the nearest object is
indicated by a tone sounding at various
intervals. As the distance between
vehicle and object decreases, the inter-
vals between the tones become shorter.
If the distance between the vehicle and
a detected object is less than 1ft
(30 cm), then a continuous tone will go
off.
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 refer the problem to your
BMW center.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
detected. This applies especially in
those cases where the system
approaches the physical limits of ultra-
sonic measurement, 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 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 a distance of more than 4 in
(10 cm).<

ASC+TThe conceptThis systems enhances driving stability
and traction, especially when you are
just starting off, accelerating or in
curves.
ASC+T recognizes the danger present
in traction loss and will increase driving
stability and traction by reducing the
engine's output, and if necessary, by
applying the brakes to the rear wheels.
ASC+T is available as soon as the
engine starts up.
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:
ASC+T controls the drive and braking
forces.
If the indicator lamp fails to go out after
the engine is started, or if it comes on
during normal driving and stays on:
There is a system malfunction or the
system was deactivated with the
button. Consequently, interventions to
increase driving stability (as described
in the preceding column) are not avail-
able. You can still drive the vehicle
perfectly well without ASC+T.
Please consult your BMW center in the
event of a fault, refer to pages 21
and 22.
Deactivate the ASC+T Press the button; the indicator lamp
comes on and stays on.
The illustration shows the arrangement
of the buttons if the vehicle is fully
equipped. This may vary, depending on
the equipment actually installed.
In the following rare situations, it may
be effective to deactivate the ASC+T
for a brief period:
>When rocking the vehicle or starting
off in deep snow or on loose
surfaces.
>When driving with snow chains.
Refer also to page 121.
To maintain vehicle stability,
always drive with the ASC+T
activated whenever possible.<460de312

DSC
* Ð BMW 325i
The concept DSC helps maintain vehicle stability,
even in critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, the system recog-
nizes unstable vehicle conditions
(understeering or oversteering, for
example) and helps hold the vehicle on
a sure course by intervening via the
engine and by braking intervention at
the individual wheels.
The DSC is operational every time you
start the engine. DSC contains the
functions of ADB and CBC, refer to
page 117.
The ADB (Automatic Differential
Braking) copies the function of conven-
tional differential and transverse lock
through brake intervention, and
increases traction whenever conditions
merit, e. g. when driving on snow-
covered roads.
If the DSC is switched off the ADB will
still be in ready mode.
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:
DSC is active and governs the drive
force and braking force.
The indicator lamp lights up continu-
ously:
The DSC has been turned off via the
switch; ADB is ready to use.
ADB intervention is not indicated.
The indicator lamp and the
brake warning lamp lights up
continuously:
The DSC, ADB and DBC have
been switched off via the button
or are defective.
Indicator and warning lamps for
Canadian models.
You can continue to drive the vehicle
normally, but without DSC. Please
consult your BMW center in the event
of a malfunction, refer to pages 21
and 22.
Deactivate DSC/activate ADBPress the DSC button briefly, the indi-
cator lamp lights up continuously.
The DSC has been switched off; ADB is
operational.
In the following exceptional circum-
stances, it may be effective to deacti-
vate the ADB for a short period:
>When rocking the vehicle or starting
off in deep snow or on loose
surfaces.
>When driving on snow-covered
grades, in deep snow, or on a snow-
covered surface that has been
packed down from being driven on.
>When driving with snow chains.
Refer also to page 121.
The gain in traction is achieved by a
reduction in stabilizing intervention.460de313

DSC Ð BMW 325xiThe conceptDSC maintains vehicle stability, even in
critical driving situations.
The system enhances vehicle stability
during acceleration and when starting
up from a full stop, and optimizes trac-
tion as well. In addition, it recognizes
unstable vehicle conditions, such as
understeering or oversteering, and, as
far as is possible within the laws of
physics, helps keep the vehicle on a
steady course by reducing the engine
output and brake applications to the
individual wheels.
The DSC is operational every time you
start the engine. DSC contains ADB-X
und DBC, refer to page 118.
The ADB-X (Automatic Differential
Braking) replaces the function of
conventional differential and transverse
lock through brake intervention, and
increases traction whenever conditions
merit, e. g. when driving on snow-
covered streets.Indicator lamp
The indicator lamp on the instru-
ment cluster will go out shortly
after the ignition has been
started. Refer to pages 21, 22.
If the indicator lamp flashes:
DSC controls the drive and braking
forces.
The indicator lamp stays lit:
DSC is switched off via the switch;
ADB-X is operational.
ADB-X intervention not indicated.
If the indicator lamp does not go
out after repeatedly pressing the
DSC switch, then the DSC and the
ADB-X are defective, and the interven-
tion described to the right is then no
longer available.<
The vehicle will remain completely
operational, however, without DSC. In
the event of a fault, please see your
BMW center. Refer to pages 21, 22.
Deactivate the DSCPress the DSC button; the indicator
lamp comes on and stays on.
The DSC has been switched off and the
ADB-X is designed for maximum
output.
In the following exceptional circum-
stances, it may be effective to deacti-
vate the DSC for a short period:
>When rocking the vehicle or starting
off in deep snow or on loose
surfaces.
>When driving with snow chains. Refer
also to page 121.
To maintain vehicle stability,
always drive with the DSC on
whenever possible.<460de313

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 system to "learn"
the correct tire inflation pressure, first
check the tire inflation pressure in all
tires. Then compare these pressures
with the tire inflation pressure chart
(page 29) 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
normal.
Activate the system Depending on the type of equipment,
the switch either has the letters RDC on
it or the RDC-symbol.
1 Turn the ignition key to position 2
(do not start the engine).
2 Press the switch long enough for the
indicator lamp in the instrument
cluster to light up yellow for a few
seconds.
3 After a few minutes driving time, the
RDC sets the current inflation pres-
sure in the tires as the target values
to be monitored.
You will only have to repeat this proce-
dure following a correction of the tire
inflation pressure. Otherwise, the RDC
functions automatically when the igni-
tion key is in position 2, and thus oper-
ates whenever the vehicle is driven.460us297
Loss of tire pressureIf the inflation pressure has dropped
significantly over a long period of time
(which is normal for any tire), the indi-
cator lamp will come on with a yellow
lamp.
This alerts you that you should have the
tires inflated to the specified pressures
as soon as possible.
If you are prompted to check the
tire pressure shortly after a
correction has been made, this indi-
cates that the corrected values were
not accurate. Please check the inflation
pressure again and make corrections
according to the inflation pressure
table. Then activate the system once
again.<
