Mirrors AirbagsInterior rearview mirror with
automatic dimming feature
*
This mirror automatically responds to
glare by dimming through an infinitely
variable range. It automatically reverts
to its clear, undimmed mode whenever
you select reverse.
To ensure that the mirror continues to
operate efficiently, ensure that the area
adjacent to the photocells remains
clean and unobstructed. One photocell
is integrated within the mirror's lens
(arrow), while the other is located at an
offset position on the rear of the mirror.
Refrain from attaching stickers or other
objects to the windshield in the area
immediately behind the rearview mirror.

3 Side airbags on the driver and
passenger sides (front and rear
*)
Protective effectThe front airbags protect the vehicle's
occupants during frontal impacts in
which the protection provided by the
safety belts alone might not be enough
to prevent injury. The head airbags and
side airbags help provide protection in
the event of a collision from the side.
Each of the side airbags is designed to
help support the seat occupant's upper
body. For information on correct sitting
posture refer to page 40.
Indicator lamp
The indicator lamp displays the
operational status of the airbag
system from ignition key posi-
tion 1.
System operational:
>The indicator lamp comes on briefly
when you turn the ignition key to
position 1 or higher.
System malfunction:
>The indicator lamp fails to go out
after the engine is started, or comes
on in the course of normal vehicle
operation.
Because a system malfunction could
prevent the airbags from deploying in
the event of a severe impact within their
normal activation range, you should
always respond to any problems by
having them corrected at your BMW
center as soon as possible.
The side airbags in the rear
passenger area
* of your vehicle
may already have been deactivated,
either at the time of manufacture or by a
BMW center. You may have them acti-
vated if you desire to do so. Please
contact your BMW center for additional
information.<

Airbags
The airbags do not respond to
minor collisions, rear impacts, or
to some kinds of vehicle rollovers.<
For your safety, comply with the
following instructions for the
airbags. If you do not, the airbags may
not be able to provide their maximum
protection. All passengers in the vehicle
should be aware of and comply with
this information:
The airbags are supplemental restraint
devices designed to provide extra
protection; they are not a substitute for
safety belts. Wear your safety belt at all
times. The airbags will not be triggered
in the event of a minor accident, a
vehicle rollover, or collisions from the
rear. In these instances, the safety belt
provides optimal protection.
Airbags are located under cover panels
in the steering wheel, in the instrument
panel, in the side trim panels in the
front and rear
*, in the roof panels, and
in the sides of the inside roof lining.
Adjust your seat to a position that
provides maximum distance between
you and the steering wheel, the instru-
ment panel and the door while still
allowing comfortable and safe access
to all vehicle controls.
To avoid sustaining hand and arm inju-
ries, always grasp the steering wheel
on the rim with the hands at the 9 and
3 o'clock positions. Do not place your
hands on the center pad.
Never allow any objects to obstruct the
area between the airbag and an occu-
pant.
Do not use the cover panel above the
passenger-side airbag as a storage
area.
Do not apply adhesive materials to the
cover panels of the airbags, cover them
or modify them in any other way.
Do not install a rear-facing child-
restraint system in the front passenger
seat of this vehicle.
Children under 13 years of age and less
than 5 ft (150 cm) tall should ride only in
the rear seat.
Infants or small children should never
be held on the lap of a passenger.
If your vehicle is equipped with side
airbags in the rear passenger area
*, be
sure that child restraints are mounted
correctly with the greatest-possible
distance between them and the airbags
in the side trim panels. Do not allow
children to lean out of the child's seat in
the direction of the side trim panels. If
they do so, serious injuries can occur if
the airbag is triggered. upright and be properly restrained
(infants and small children in appro-
priate child-restraint systems; larger
children and adults using the safety
belts). Never let an occupant's head
rest near or on a side airbag because
the inflating airbag could cause a
serious or fatal injury. Please note that
the word Airbag imprinted on the door
trim panel indicates the airbag's loca-
tion.
Accident research shows that the
safest place for children in an
automobile is in the rear seat. However,
a child sitting in the rear seat and not
properly restrained may place his or her
head on or near the airbag, if so
equipped. For example, a child Ñ even
though belted Ñ may fall asleep with his
or her head against the side airbag. It
may be difficult for a driver to ensure
that children in the rear seat will remain
properly positioned at all times and not
place their heads on or near the side
airbag.
Therefore, we recommend that the
rear-seat side airbags, if installed in the
vehicle, be deactivated if children will
travel in the rear seat.
The rear side airbags may already have
been deactivated, either at the time of

Transporting children safelyCommercially available child seats
complying with the legal standards are
designed to be secured with a safety
belt or with the safety belt portion of a
combination lap/shoulder belt. Improp-
erly or inadequately installed restraint
systems can increase the risk of injury
to children. Always read and follow the
instructions that come with the system.
If you use a child-restraint system with
a tether strap, three additional tether
anchorage points (refer to the arrows in
the illustration) have been provided.
Depending on the location selected
for seating in the rear passenger area,
attach the tether strap to the
corresponding anchorage point to
secure the child-restraint system.
Remove the cover first on the middle
location.
If the respective seating position is
fitted with a headrest lift the headrest
and pass the tether strap between the
headrest and the backrest.
Adjust the tether strap according to the
child-restraint manufacturer's instruc-
tions.
Before installing any child-restraint
device or child seat, please read
the following:
Never install a rear-facing child-restraint
system in the front passenger seat of this
vehicle.
Your vehicle is equipped with an airbag
supplemental restraint system for the
front passenger. Because the backrest
on any rear-facing child-restraint system
(of the kind designed for infants under 1
year and 20 lbs/9 kg) would be within the
airbag's deployment range, you should
never mount such a device in the front
passenger seat, as the impact of the
airbag against the child restraint's back-
rest could lead to serious or fatal injuries.
If it is necessary for a child (not an infant)
to ride in the front seat, certain precau-
tions should be taken. First, move the
passenger seat as far away from the
instrument panel as possible. This
important precaution is intended to
maximize the distance between the
airbag and the child. Older children
should be tightly secured with the safety
belt. Younger children should be
secured in an appropriate forward-
facing child-restraint system that has
first been properly secured with a safety
belt. Never install a rear-facing child-
restraint system in the front passenger
seat.
We strongly urge you to carefully read
and observe the instructions for installa-
tion and use provided by the child
restraint's manufacturer whenever you
use such a device.
Always ensure that all occupants (of all
ages) remain properly and securely
restrained at all times.<
All rear seating positions in your vehicle
meet the recommendations of
SAE J1819, an industry standard
recommended practice for securing
child-restraint systems in motor vehi-
cles.

Park Distance Control (PDC)
*
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.
The system features four ultrasonic
sensors mounted in your rear bumper.
The monitoring range for the two corner
sensors extends outward roughly 2 ft
(60 cm), while two centrally located
sensors detect objects at distances of
up to approx. 5 ft (1.5 m).
The 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. PDC is deacti-
vated when you shift back out of
reverse.
Acoustic 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. 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 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 or wedge-shaped
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 will continue to operate effec-
tively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Always maintain a distance of more
than 4 in (10 cm).<

Automatic Stability Control plus Traction (ASC+T)

The conceptThis system optimizes vehicle stability
and traction, especially when just
starting off, when accelerating or when
going through 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 ready each time you start the
engine.
Indicator lamp
The indicator lamp in the instru-
ment cluster will go out shortly
after the ignition has been
switched on, refer to pages 18, 19.
The indicator lamp flashes:
ASC+T controls the drive and braking
forces.
The indicator lamp fails to go out
after the engine is started, or it
comes on during normal driving and
stays on:
There is a system malfunction or the
system was switched off with the
button. Consequently, interventions to
increase driving stability (as described
in the preceding column) are no longer
available. You can still drive the vehicle
perfectly well without ASC+T.
In the event of a fault, please consult
your BMW center, refer to
pages 18, 19.<
To switch off ASC+TPress the button; the indicator lamp
comes on and stays on.
The illustration depicts 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 switch off 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.
To maintain vehicle stability,
always drive with the ASC+T acti-
vated whenever possible.<

Automatic Stability Control plus Traction (ASC+T)To switch ASC+T back onPress the button again; the indicator
lamp goes out.
The laws of physics cannot be
repealed, even with ASC+T. 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.<

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.

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.
