For your personal safety when adjusting
the seat position, please follow the
instructions below carefully:
Never try to adjust your seat while
operating the vehicle. The seat
could respond with an unexpected
movement, and the ensuing loss of
vehicle control could lead to an acci-
dent.
Be sure that the safety belt remains
firmly against your body at all times. In
the event of a frontal impact, a loose lap
belt could slide over the hips, leading to
abdominal injury. In addition, the safety
belt's restraint effectiveness is reduced
if the belt is worn loosely.
Never ride with the backrest reclined to
an extreme angle (especially important
for the front passenger to remember).
If you do so, there is a risk that you will
slide under the safety belt in an acci-
dent, thus reducing the protection
provided by the safety belt.<
Correct sitting postureTo reduce strain on the spinal column,
sit all the way back in the seat and rest
your back fully against the backrest.
The ideal sitting posture is achieved
with your head extending from your
spine in a straight line. For long-
distance driving, you may wish to
increase the backrest angle slightly to
reduce muscular tension. You should
be able to grasp the steering wheel at
its highest point with your arms slightly
bent.
After a seat adjustment, adjust the
height of the safety belt also. Refer to
page 54.1 Longitudinal adjustment
Pull the lever and slide the seat to the
desired position.
After releasing the lever, apply pres-
sure to the cushion to ensure that the
latch engages securely.
2 Cushion height
Pull the lever and apply weight to or
remove weight from the seat as
required.

Adjusting steering wheel
Your BMW center can adjust your
vehicle's systems in such a
manner that your personalized settings
are automatically set for the seat and
outside mirror positions when you
unlock the vehicle with your personal
remote control.<
If you make use of this method of
adjustment, be sure that the foot-
well behind the driver's seat is unob-
structed before unlocking the vehicle.
If you fail to do so, persons or objects
could be injured or damaged if the seat
should move backward.<
Passenger side exterior mirror tilt
function(automatic curb monitor)
1 Move the mirror selector switch 1 to
the "driver's mirror" position.
2 When the selector lever is placed in
"Reverse," the passenger-side mirror
tilts downward. This allows the driver
to see the area directly adjacent to
the vehicle during parking (curbs,
etc.).
You can deactivate this automatic
feature: set the mirror selection switch
to the "passenger side" position.460us301
1 Push the locking lever downward.
2 Adjust the steering wheel (fore/aft
and up/down) to the desired position.
3 Pull the lever back in to clamp the
steering wheel in the new position.
Do not adjust the steering wheel
while the vehicle is moving. If you
do so, there is a risk of accident from
unexpected movement.<460de073

Airbags
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.<
The illustration depicts schematically
the primary directions of vehicle impact
that initiate an airbag deployment.
The airbags will not be triggered in
the event of a minor accident, a
vehicle roll-over, or collisions from the
rear.c
460de141
Operational status
The indicator lamp in the instru-
ment cluster displays the opera-
tional status of the airbag
system when the ignition key is in posi-
tion 1 and higher.
System operational:
>The indicator lamp comes on briefly
then goes out.
System malfunction:
>The indicator lamp fails to come on.
>The indicator lamp comes on briefly
before going out, and then lights up
again.
If there is a system malfunction, there is
a risk that the airbags will not be trig-
gered within their normal response
range, even if the level of impact would
normally have triggered them.
Have your BMW center inspect the
system immediately.
The airbag indicator lamp also
comes on if the safety belt
tensioners have been triggered.<
Sitting correctly with airbags
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 roll-over, 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 dashboard,
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.

0 Steering lock engaged The key can only be inserted or
removed in this position.
After removing the key, turn the
steering wheel slightly to the left or right
until the lock engages.
If the key is not removed, an acoustic
signal is sounded after the driver's door
has been opened.
Vehicles with automatic transmis-
sion:
Do not move the selector lever from the
"Park" position until the engine is
running (ignition key at position 2).
In order to turn the key back to posi-
tion 0 or to remove it, move the selector
lever into position "Park" first (Inter-
lock).<460de022
1 Steering lock disengaged Turning the steering wheel slightly to
the right or left often makes it easier to
turn the key from 0 to 1.
Individual electrical devices are ready
for operation.2 Ignition onAll electrical equipment and accesso-
ries are available for use.3 Starting the engine
Vehicles with manual transmis-
sion: depress the clutch when
starting the vehicle. A lockout prevents
the engine from starting if the clutch is
not depressed.c
Before starting>Engage the parking brake
>Be sure that the shift lever is in
"Neutral" or "Park" if the vehicle is
equipped with an automatic transmis-
sion
>Depress the clutch pedal.
Do not run the engine in enclosed
areas. The exhaust gases contain
carbon monoxide, an odorless and
colorless, but highly toxic gas.
Breathing the exhaust gases poses an
extreme health risk, and can lead to
unconsciousness and death.
Do not leave the vehicle unattended
with the engine running. An unat-
tended vehicle with a running engine
represents a potential safety hazard.<

Starting the engine Switching off the engine Do not press the accelerator pedal
while starting the engine.
Do not actuate the starter for too
short a time, but do not turn it for
more than approx. 20 seconds. Release
the ignition key immediately when the
engine starts.
Do not allow the engine to warm up by
leaving it running while the vehicle
remains stationary. Instead, begin
driving immediately at a moderate
engine speed.<
If the engine does not start on the first
attempt (if it is very hot or cold, for
instance):
>Press the accelerator pedal halfway
down while engaging the starter.
Cold start at extremely low tempera-
tures, from approx. +5 7 (-15 6)
and at elevations above 3,300 feet
(above 1,000 meters):
>On the first start attempt, engage the
starter for a longer period (approx.
10 seconds).
>Press the accelerator pedal halfway
down while engaging the starter.
Engine idle speed is controlled by the
engine computer system. Increased
speeds at startup are normal and
should decrease as the engine warms
up. If engine speed does not decrease,
service is required.
To prevent the battery from
discharging, always deactivate elec-
trical devices that are not in use. Switch
the ignition off when the vehicle is not
being driven.Turn the ignition key to position 1 or 0.
Do not remove the ignition key
while the vehicle is still moving.
If you did so, the steering lock would
engage when the steering wheel is
turned.
When you leave the vehicle, always
remove the ignition key and engage the
steering lock.
Vehicles with manual transmission:
Always engage the parking brake when
parking on slopes and inclined
surfaces. Placing the lever in 1st gear
or reverse may not provide adequate
resistance to rolling.
Vehicles with automatic transmission:
Place the selector lever in "Park."<

DSC
* Ð BMW 320i, 325i, 330i
The conceptDSC maintains 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, it recognizes
unstable vehicle conditions, such as
understeering or oversteering, and, as
far as is possible within the laws of
physics, helps keep the car on a steady
course by reducing the engine spped
and brake applications to the individual
wheels.
The DSC is operational every time you
start the engine. DSC contains the
functions of ADB and CBC, refer to
page 119.
The ADB (automatic differential braking)
copies the function of conventional
differential and transverse lock through
brake intervention, and increases trac-
tion 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 on the instru-
ment panel 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 has been switched off by the
button; ADB is operational.
ADB intervention is not indicated.
The indicator lamp and the
brake warning lamp stay lit:
DSC, ADB and DBC have been
switched off via the button or
are defective.
Indicator and warning lamps for
Canadian models.
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.
Switch off the DSC/activate the
ADBPress the DSC button briefly; the indi-
cator lamp comes on and stays on.
The DSC has been switched off; ADB is
operational.
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 on snow-covered
grades, in deep snow, or on a snow-
covered surface that has been
packed down from being driven on
>or when driving with snow chains.
Refer also to page 122.
The gain in traction is achieved by a
reduction in stabilizing intervention.460de313

DSC Ð BMW 325xi, 330xiThe 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 car on a steady
course by reducing the RPMs and
brake applications to the individual
wheels.
The DSC is operational every time you
start the engine. DSC contains the
functions of ADB-X and CBC, refer to
page 119.
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 roads.Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition.
Refer to pages 21, 22.
Indicator lamp flashes:
DSC controls the drive and braking
forces.
Indicator lamp lights up permanently:
DSC has been switched off via the
button; ADB-X is operational.
ADB-X intervention is not indicated.
If the warning lamp does not go
out after pressing the DSC button
repeatedly, then both the DSC and
ADB-X are defective. Consequently,
interventions to increase driving
stability (as described in the preceding
column) are not available.<
You can drive perfectly well without
DSC. Please contact your BMW center
in the event of a fault, refer to
pages 21, 22.
Switching the DSC offPress 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 122.
To maintain vehicle stability,
always drive with the DSC on
whenever possible.<460de313
