Keys1 The master keys with remote control
determine the functions for the Key
Memory; refer to page 52
There is an extended-life battery in
every master key that is charged
automatically in the steering lock as you
drive.
For this reason, if you have a master key
that is otherwise not used, use that key
at least once every year while driving for
an extended period to charge the
battery. Refer also to page 35.<

such as in your wallet. This key is not
intended for constant use 46cde059
3 Door and ignition key
The lock for the glove compartment
cannot be operated with this key,
which is an advantage when using for
valet parking, for instance
Replacement keysReplacement keys are available exclu-
sively through your authorized BMW
center. Since the keys belong to a
security system, your BMW center is
obligated to ensure that a person
requesting a key is authorized to do so
(refer to "Electronic vehicle immobilizer"
on page 35).
If possible, take all of the master
keys that belong to the vehicle
with you when you pick up your
replacement key.
Whenever you receive a new replace-
ment key, turn that key to position 2 in
the ignition lock once (ignition switched
on) and then back. This allows the elec-
tronic vehicle immobilizer to "learn" the
new key.<

Opening and closing Ð from the outside Using the remote controlThe remote control gives you an excep-
tionally convenient method for
unlocking and locking your vehicle.
Furthermore, it provides two additional
functions that only the remote control
can execute:
>Switching on the interior lamps, refer
to page 38.
With this function, you can also
"search for" your car Ð when parked
in an underground garage, for
instance.
>Opening the rear window, refer to
page 39.
The rear window will open slightly,
regardless of whether it was previ-
ously locked or unlocked.
When you unlock the vehicle, the anti-
theft system is deactivated, the alarm
system is disarmed, and the interior
lamps are turned on. When you lock the
vehicle, the systems are activated and
armed, and the lamps go off.
You can have a signal set as an
acknowledgment message that
the vehicle is closed correctly.<
Master keysKeys with remote control are master
keys. Refer to page 32.
Children might be able to lock the
doors from the inside. For this
reason, always take the vehicle's keys
with you so that the vehicle can be
opened again from the outside at any
time.<463de024
Master keys that are used repeat-
edly are always ready for opera-
tion since the battery in the key is
charged automatically in the steering
lock as you drive.
If it is no longer possible to unlock the
vehicle via the remote control, the
battery is discharged. Use this key while
driving for an extended period in order
to recharge the battery. Refer also to
page 32.
To prevent unauthorized use of the
remote control, surrender only the door
and ignition key or the spare key (refer
to page 32) when leaving the vehicle for
valet parking, for example.
In the event of a system malfunction,
please contact your BMW center. You
can also obtain replacement keys
there.<

For maximum safety when adjusting
the seat position, please observe the
following:
Never try to adjust your seat while
driving the vehicle. The seat could
respond with an unexpected move-
ment, and the ensuing loss of vehicle
control could lead to an accident.
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.
While driving, do not recline the back-
rest too far (this applies to the
passenger side especially), because
otherwise there is the danger of sliding
underneath the safety belt during an
accident, thereby negating the safety
belt's protection.<
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 when your
head forms a straight line with your
spine.
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 53.1 Backward/forward 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.<
When this setting is used, be sure
that the footwell behind the
driver's seat is clear before unlocking
the vehicle. If you fail to do so, any
persons or objects behind the seat
could be injured or damaged by a rear-
ward movement of the seat.<

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 mirror-selector switch to
the "passenger mirror" 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

AirbagsSitting 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 allo-
wing 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 car.
Children under 13 years of age and
children less than 5 feet (150 cm) tall
should only ride in the rear seat.
Infants or small children should never
be held on the lap of a passenger.
If your car is equipped with side airbags
in the rear passenger area
*, be sure
that child restraints are mounted
correctly and provided with the grea-
test-possible distance between 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
as 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 so
equipped, be deactivated if children will
travel in the rear seat.
The rear seat side airbags may already
have been deactivated, either at the
time of manufacture or by a BMW

0 Steering lock engaged The key can be inserted or removed in
this position only.
After removing the key, turn the
steering wheel slightly to the left or right
until the lock engages.
If the key has been left in the ignition,
an acoustic signal will sound after the
door has been opened.460de022
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 to position 0 or
to remove it, first move the selector
lever to the position "Park" (Interlock).<
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.<
Before starting>Engage the parking brake.
>Put the manual-shift gear lever in idle
or in P for an automatic transmission.
>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.
Never leave the vehicle unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a potential safety hazard.<
Do not press the accelerator pedal
when starting the engine.
Do not actuate the starter for too
short a time, but do not keep
turning 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, drive off
immediately at a moderate engine
speed.<

Starting the engine Switching off the engine 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 very low temperatures
approx. +5 7 (Ð15 6) at high altitude
over 3,300 ft (1000 m):
>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 start-up are normal and
should decrease as the engine warms
up. If engine speed does not decrease,
service is required.
To prevent the battery from dischar-
ging, always switch off electrical
devices which are not in use and the
ignition when the vehicle is not being
driven.Turn the ignition key to position 1 or 0.
Never 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, since 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."<

Mode selectionIn ignition key positions 1 and 2, you
can call up information from the
computer using the button in the turn
signal lever. By pressing the button
briefly in the direction of the steering
column, you can call up a new function
for display.
The displays appear in the following
order:
Time, outside temperature, average fuel
consumption, cruising range, average
vehicle speed.
Starting with ignition key position 1, the
last active setting is displayed.460de084
Outside temperature You can change the units of measure-
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.<

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
