Dynamic Stability Control (DSC)
* Ð BMW 325i
Switch the DSC and ADB offHold the DSC button down for at least
3 seconds. The indicator and the yellow
brake warning lamps will remain on
continuously.
The systems for enhancing stability and
traction are deactivated, and there is no
active braking intervention or torque
control.
To maintain vehicle stability,
always drive with the DSC
switched on whenever possible.<
Switch DSC and ADB back onPress the button again; the indicator
lamps will go out
The laws of physics cannot be
repealed, even with DSC. It will
always be the driver's responsibility to
drive in a manner that matches road
conditions. This is why you should not
use the additional safety margin the
system provides as an excuse to take
risks.
When ADB is in its standby mode, DSC
is deactivated; DSC does not intervene
to enhance vehicle stability under these
conditions.
Do not make any modifications to the
DSC system. Allow only authorized
technicians to perform service proce-
dures on the DSC.<
Dynamic Brake Control (DBC)DBC is an integral component of the
DSC system.
The system responds to sudden, high-
intensity applications of force to the
brake pedal by automatically braking
the vehicle with maximum boost to
achieve the shortest-possible braking
distances during "panic stops". This
system exploits all the benefits of ABS.
Do not reduce the pressure exerted
against the brake pedal until the
braking maneuver has been completed.
DBC is deactivated when you release
the brake pedal.

OverviewControlsMaintenanceRepairsDataIndex
Hill Descent Control (HDC) Ð BMW 325xiThe conceptBy reducing the vehicle's speed on
steep downhill stretches, HDC main-
tains predictable vehicle handling
response to provide you with control of
your BMW during extreme descents.
The vehicle slows to a pace just slightly
faster than walking speed.
HDC is available for activation at
vehicle speeds below approx. 22 mph
(35 km/h). When driving down steep
hills, the vehicle reduces speed auto-
matically down to slightly more than
double walking speed (approx. 8 mph/
12 km/h) and then maintains this speed
at a constant.
You can use the accelerator or brakes
to vary this automatically controlled
speed within a range extending from
approx. 3 mph (5 km/h) to 15 mph
(25 km/h).
In conjunction with the multifunction
steering wheel, you can use the
+/Ð button to set the cruise control to a
target speed in the range from approx.
3 mph (5 km/h) to 15 mph (25 km/h).
HDC is automatically deactivated once
vehicle speed again exceeds approx.
35 mph (60 km/h).
To activate the systemPress the HDC button; the green indi-
cator lamp integrated within the button
comes on.
The indicator lamp flashes whenever
the system is actively intervening to
control your speed with automatic
brake applications.To deactivate the systemPress the button again, the indicator
lamp goes out.
HDC is automatically deactivated once
the vehicle accelerates to more than
35 mph (60 km/h) as well as whenever
you switch off the ignition.
To use HDCWith manual transmission:
You should always ensure that either
reverse or first gear is engaged before
using HDC, as the engine's braking
effect is most pronounced in these
gears, and only reduced engine braking
is available in higher gears.
With automatic transmission:
HDC is available for use in all ranges.System malfunctionsSignalled by the indicator lamp, which
responds to problems by going out
while HDC is in operation or by failing
to come on when you activate the
system:
HDC is temporarily not available if
brake temperature is too high.
If the DSC indicator lamp comes
on at the same time:
There is a fault in the HDC and
DSC systems. Have your BMW center
inspect this system as soon as
possible.

Flat Tire Monitor
*
The conceptAs you drive, the Flat Tire Monitor
keeps track of pressure levels in all four
tires in order to detect and warn of any
substantial pressure loss.
The system actually detects pressure
loss by monitoring differences in the
relative speeds of the four wheels. It
interprets variations outside specified
limits as severe pressure loss, and then
responds by generating a warning.
To initialize the systemInitializing is necessary to familiarize the
system with the correct inflation pres-
sure.
Repeat this process after any changes
in tire inflation pressure, tire rotation or
replacement. Do not carry out further
system initialization after adjusting the
inflation pressure and letting the system
"learn" the correct pressures.
1. Check the tire inflation pressure in all
the tires, comparing them with the
inflation pressure table on page 25,
and correct their pressure if neces-
sary
2. Turn the ignition key to position 2
3. Press button as long as you need to
until the indicator lamp in the instru-
ment cluster lights up. After a little
while, the indicator lamp will go out
by itself
4. After a few minutes driving time, the
Flat Tire Monitor adopts the current
pressure levels as the reference, and
from that point on, can detect and
report a flat tire.

Flat Tire Monitor
*
Activate/deactivate the systemThe Flat Tire Monitor automatically
assumes operation whenever you turn
the ignition key to position 2. Unless
manually deactivated, it is always on
during normal vehicle operation.
To deactivate the system: press the
button, the yellow indicator lamp comes
on.
To activate the system: press the
button again, the indicator lamp goes
out.
You should deactivate the system
before driving with snow chains, as the
chains can generate spurious warnings
and/or prevent the system from
detecting actual pressure loss.
In the event of a flat tire
The red warning lamp in the
instrument cluster lights up to
warn of pressure loss and tire
failure. This visual alert is accompanied
by an acoustic warning signal. Reduce
your speed immediately, and steer and
brake gently as you bring the vehicle to
a stop.
To reset the warning lamp: after
replacing the flat tire you will need to
reset the red warning lamp manually:
maintain pressure on the Flat Tire
Monitor button until the warning lamp
goes out. Then reinitialize the system.
The Flat Tire Monitor cannot
provide you with advance warning
of sudden and severe tire damage
caused by external factors.
The system also does not detect the
gradual and minor loss of pressure that
all tires display over extended periods
of time.<
Check the tire inflation pressures
on a regular basis, correcting
them as necessary, refer to page 24.
The system may respond to operation
on slippery or snow-covered road
surfaces with false warnings or delays
in detecting actual pressure loss.
Performance-oriented driving (slip at
the drive wheels, high rates of lateral
acceleration) can also increase the time
that the Flat Tire Monitor requires to
detect a flat tire.<
System malfunctionsThe yellow indicator lamp in the instru-
ment cluster lights up and remains on
until the problem is corrected.
Please refer the problem to your BMW
center.

Parking lamps/Low beamsParking lamps
The front, rear and side vehicle
lighting is switched on. You can
use the parking lamps for
parking. For lighting on one side for
parking as an additional feature, refer to
page 83.
Low beams
When the ignition is switched off
while the low beams are on, the
headlamps go out and only the
parking lamps remain on.
Follow me home lamps
When you activate the headlamp
flasher after parking the vehicle with the
lamps turned off, the low-beam head-
lamps will come on for a short time.You
can also have this function deacti-
vated.<
LIGHTS ON warningWhen you open the driver's door after
having turned the ignition key to posi-
tion 0, you will hear an acoustic signal
for a few seconds to remind you if the
lamps have not been switched off.Daytime driving lamps
*
If you desire, the lamp switch can be
left in the second position:
When the ignition is switched off, the
external lighting is also switched off.
You can have the activation
settings for the daytime driving
lamps programmed on your vehicle.<
Automatic headlight 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 lights
remain on constantly when you
switch on the front fog lamps after the
headlights have come on automati-
cally.<
Automatic headlight control
cannot serve as a substitute for
the driver's judgement in determining
when the vehicle lights 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 headlights on manu-
ally.< You can have the sensitivity of
your vehicle's automatic head-
light control adjusted.<

Air conditioningAir supply
You can select blower speeds
from 1 to 4. The heating and
ventilation become more and
more effective as the air
supply settings are increased. In
position 0, the blower and the heater
are switched off. The outside air supply
is blocked in position 0.
Temperature
In order to increase the
temperature of the passenger
compartment, turn it to the
right (red). The temperature of
the incoming air is kept constant.
Air distribution
You can direct air to flow onto
the windows , toward the
upper body and into the
footwell . All intermediate
settings are possible. In the setting,
there is a low flow of air onto the
windows to keep them free of conden-
sation.
Rear window defroster
When the rear window defroster
is activated, the indicator lamp
comes on. The rear window defroster
switches off automatically.
At outside temperatures colder
than approx. 39 7 (+4 6) the
rear window defroster automatically
assumes operation within 5 minutes
after the engine is started.<
Air conditioning
The air is cooled and dehumidi-
fied and Ð depending on the
temperature setting Ð rewarmed when
the air conditioning is switched on.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started. Switching on the air
conditioning will reduce condensation
forming on the windows.
As the air-conditioning system
operates, condensation forms
within the system. This moisture is
conducted to an outlet beneath the
vehicle; it is thus not unusual for a small
puddle to form under the car while the
system is running.<
Recirculated-air mode
You can respond to unpleasant
external odors by temporarily
excluding the supply of outside air. The
system then recirculates the air
currently within the vehicle.
If the windows fog over in the
recirculated-air mode, switch it off
and increase the air supply as
required.<

Automatic climate control
*
Automatic recirculated-air control
(AUC)
You can respond to unpleasant
external odors or pollutants by
temporarily stopping the flow of outside
air. The system then recirculates the air
currently within the vehicle.
Press the button repeatedly to select
one of three different operating modes.
>Indicator lamps off: outside air supply
is on
>Left indicator lamp on Ð AUC mode:
the system recognizes pollutants in
the outside air and blocks the flow of
air when necessary. The system then
recirculates the air currently within
the vehicle.
Depending on the air quality, the
automatic system then switches back
and forth between outside air supply
and recirculation of the air within the
vehicle
>Right indicator lamp on: the flow of
external air into the vehicle is perma-
nently blocked. The system then
recirculates the air currently within
the vehicle.
If the windows fog over in the
recirculated-air mode, switch the
recirculated-air mode off and increase
the air supply as required.<
Rear window defroster
When the rear window defroster
is activated, the indicator lamp
comes on. The rear window defroster
switches off automatically.
At outside temperatures colder
than approx. 39 7 (+4 6) the
rear window defroster automatically
assumes operation within 5 minutes
after the engine is started.<
Draft-free ventilationYou can adjust the blower controls for
the upper body area to obtain the
optimum airflow rates and directions for
your personal requirements:
1 Rotary dials for infinitely-variable
opening and closing of the vent
outlets
2 Selector levers for airflow direction
3 Rotary dial 3 allows you to control the
temperature of the airflow from these
outlets as desired
