SeatsWhen adjusting your seat, always
observe the following precautions
Never try to adjust your seat while
operating the vehicle. The seat
could respond with unexpected move-
ment, and the ensuing loss of vehicle
control could lead to an accident. Never
ride with the backrest reclined to an
extreme angle. This is especially impor-
tant for the front passenger to remem-
ber. If you do so, there is a risk that you
will slide under the safety belt in an
accident, thus reducing the protection
provided by the safety belt.
With the wind deflector in place:
Do not push the front seats all the way
back, otherwise the wind deflector will
be damaged.<

Rear head restraints
To avoid possible violation of traf-
fic laws, never retract the head
restraints unless the rear seats are
empty. Always ensure that the head
restraints are raised before transporting
passengers in the rear seat.<
To completely lower the rear head
restraints:
1. Press the button and hold it down
2. Push the head restraint down from
above.
Raising the rear head restraintsRaise the head restraints until you hear
them click into place.
Do not remove the rear head
restraints, as this would damage
them.<
For further information, please consult
your BMW center.
Do not use the rear head
restraints as storage shelves.
Always keep the travel path for the roll-
over protection system free and clear.
Never place protective covers or similar
items on the head restraints. See also
the labels on the head restraints.<
Entering the rearThe seat-integrated safety belt system
allows for easy access to the rear.

ally:
Press the edge of the lens.
For storing mirror settings, refer to Seat
and mirror memory on page 57.
The mirror on the passenger's
side is convex. When estimating
the distance between yourself and
other traffic, bear in mind that the
objects reflected in the mirror are closer
than they appear. This means that esti-
mates of the distance to following traffic
should not be regarded as precise.<
Electric defrostingBoth mirrors are automatically heated
when you turn the ignition key to posi-
tion 2.

Interior rearview mirrorTo reduce glare from vehicles behind
you when you are driving at night, tilt
the mirror by turning the button.
Vehicles without alarm system:
Tilt the small lever forward.
Interior rearview mirror with
automatic dimming feature*This mirror automatically responds to
ambient light and headlamp glare from
following vehicles by dimming through
an infinitely variable range and auto-
matically reverts to its clear, undimmed
setting whenever you shift into Reverse
or move the selector lever into position
R.
To ensure that the mirror continues to
operate efficiently, ensure that the pho-
tocells remain clear and unobstructed.
One photocell is integrated in the mir-
ror's lens – see arrow – while the other
is located at an offset position on the
rear of the mirror. Refrain from attach-
ing stickers or other objects to the
windshield in the area immediately
behind the rearview mirror.

61 Passenger safety systems
Airbags1Front airbags on the driver and pas-
senger sides
2Side airbags on the driver and pas-
senger sides – front and rear*Protective effectThe front airbags supplement the three-
point safety belts by providing addi-
tional protection in the event of a
severe frontal collision in which the pro-
tection afforded by the belts alone may
no longer be sufficient. The side airbags
provide protection in the event of a col-
lision from the side. They help support
the respective seat occupant's upper
body.
For information on the correct sitting
posture, refer to page 52.
The side airbags in the rear pas-
senger area* of your vehicle may
already have been deactivated 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 airbags do not deploy in
response to minor collisions, rear
impacts and certain kinds of vehicle
rollover.<
Do not apply adhesive materials to
the cover panels of the airbags,
cover them or modify them in any other
way. Do not remove the airbag restraint
system. In the event of a malfunction,
deactivation or triggered activation – as
a response to an accident – of the air-
bag restraint system, consult your BMW
center for inspection, repair or disas-
sembly. Do not modify or tamper with
either the wiring or the individual com-
ponents in the airbag system. These
include the upholstered covers on the
steering wheel, instrument panel, side
trim panels of the doors and front roof
pillars and on the sides of the headliner.
Also, do not attempt to remove the
steering wheel. Unprofessional
attempts to service the system could
lead to failure in an emergency or
undesired airbag activation, either of
which could result in personal injury. Do
not touch the individual components
immediately after the system has been
activated, as this could result in per-
sonal injury.<

At all times, occupants should sit
upright and be properly restrained
– infants and small children in appropri-
ate child-restraint systems; larger chil-
dren 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 indi-
cates the airbag's location.
Accident research shows that the saf-
est place for children in an automobile
is in the rear seat. However, a child sit-
ting in the rear seat and not properly
restrained could place his or her head
on or near the airbag, if so equipped.
For example, a child — even though
belted in — 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 seat side airbags may already
have been deactivated by a BMW cen-
ter. If you are uncertain of their status,
or wish to have the airbags activated or
deactivated, please contact your BMW
center.<
Even when all these guidelines are fol-
lowed, there is still a small residual risk
of injuries to the face, hands and arms
occurring from airbag deployment in
isolated instances.
In sensitive individuals, the ignition and
inflation noise may induce a mild hear-
ing loss that is temporary in most
cases.
Corresponding airbag warning labels
are located on both sun visors.This is the right way a child should sit in
a child restraint when rear side airbags
are provided.

This is the right way a larger child
should sit wearing the seat belt when
rear side airbags are provided.Indicator lamp
The indicator lamp indicates the
operational status of the airbag
system when the ignition key is
in position 1 or higher.
System operational:
>The indicator lamp comes on briefly
when you turn the ignition key to
position 1 or higher.
System malfunction:
>Indicator lamp does not come on or
>indicator lamp lights up continuously.
If there is a system malfunction,
there is a risk that the airbags will
not be triggered within their normal
response range, even if the level of
impact would normally have triggered
them. Have your BMW center inspect
the airbag system immediately.<

92Technology for safety and driving convenience
Park Distance Control (PDC)*The conceptPDC assists you when you back into a
parking space. Acoustic signals alert
you to the momentary distance to an
object behind your vehicle. The system
features four ultrasonic sensors
mounted in your rear bumper. The mon-
itoring 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/1.50 m.
PDC is a parking aid that can
identify objects if they are
approached slowly, as is generally the
case when parking. Avoid driving
towards objects rapidly; due to underly-
ing physical principles, the system may
otherwise alert you too late for you to
take evasive steps.<
The system starts to operate automati-
cally approx. one second after you shift
into Reverse or move the selector lever
into the R position with the ignition key
in position 2.
Let this short period elapse before
driving backwards.<
PDC is deactivated when you shift back
out of Reverse.
You can have a signal set to con-
firm that the PDC has been acti-
vated. The signal then sounds when
you shift into Reverse or move the
selector lever into the R position. indicated by a tone sounding at various
intervals. As the distance between vehi-
cle and object decreases, the intervals
between the tones become shorter. A
continuous tone indicates the pres-
ence of an object less than 1 ft/30 cm
away.
The warning signal is canceled after
approx. three seconds if the distance to
the object 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 have the problem fixed by
your BMW center.
PDC does not replace the driver's
personal responsibility for evaluat-
ing the distance between the vehicle
and any objects. Always remember that
the sensors can neither detect nor pro-
vide warnings of obstacles located
within their blind angles. This applies
especially in those cases where the
system approaches the physical limits
of ultrasonic measurement, as occurs
with tow bars and trailer couplings, and
in the vicinity of thin or wedge-shaped
objects. Moreover, low objects that
have already been detected – such as a
curb edge – can disappear out of the
detection range of the sensors before a
continuous tone sounds.
Loud sources of sound from outside or
inside the vehicle could drown out 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.<

Under these special circumstances
traction is increased by deactivating the
control systems that enhance traction
under normal conditions.Deactivating the DSC and the
DTCHold the DSC button down for at least
3 seconds. The indicator lamp and the
yellow brake warning lamp light up and
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 acti-
vated whenever possible. lamp or the indicator lamps will go out.
DTC is deactivated.
The laws of physics cannot be
repealed even with DSC. An
appropriate driving style always
remains the responsibility of the driver.
We therefore urge you to avoid using
the additional safety margin of the sys-
tem as an excuse for taking risks.
Whenever the DTC is activated, the
DSC is switched off and performs minor
stabilizing intervention.
Do not make any modifications to the
DSC system. Allow only authorized
technicians to perform service proce-
dures on the DSC.<
Flat Tire Monitor*The conceptAs you drive, the Flat Tire Monitor
keeps track of pressure levels in all four
tires. The system alerts you whenever
the inflation pressure of a tire falls sig-
nificantly below the pressure of another
tire.
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.Functional requirementsIn order for the Flat Tire Monitor to learn
the correct tire inflation pressure,
please do the following:
1. Check the tire inflation pressures in
all tires
2. Compare them with the tire inflation
pressure table on page 25 and cor-
rect them, if necessary
3. Initialize the system.
Dynamic Stability Control (DSC)

97 Lamps
Parking lamps/Low beamsParking lamps
The front, rear and side vehicle
lighting is switched on. You can
use the parking lamps to signal
the position of the vehicle when it is
parked. For lighting on one side for
parking as an additional feature, refer to
page 99.
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 lampsWhen 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
deactivated. having turned the ignition key to posi-
tion 0, you will hear an acoustic signal
for a few seconds to remind you that
the lamps have not been switched off.Daytime driving lamps*If you desire, the light switch can be left
in the second position: when the igni-
tion is switched off, the external lighting
is also switched off.
You can have the activation set-
tings for the daytime driving lamps
programmed on your vehicle. 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. –
and in the event of rain and snow. If the
low-beam headlamps are on, the LED
next to the symbol lights up.
The vehicle's external lights
remain on constantly when you
switch on the front fog lamps after the
headlamps have come on automati-
cally.<
Automatic headlamp control can-
not 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
headlamps on manually.<
You can have the sensitivity of
your vehicle's automatic head-
lamp control adjusted.<
