Interior rearview mirrorTo reduce glare from vehicles behind
you when you are driving at night, tilt
the mirror by turning the knob.
Vehicles not equipped with an alarm
system:
Fold 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 area
adjacent to the photocells remains
clean and unobstructed. One photocell
is integrated within the mirror's lens –
see arrow – while the other is located at
an offset position on the rear of the mir-
ror. Refrain from attaching stickers or
other objects to the windshield in the
area immediately behind the rearview
mirror.

54Passenger safety systems
Airbags1Front airbags on the driver and pas-
senger sides
2Head airbags for driver and front pas-
senger
3Side 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 head and
side airbags help provide protection in
the event of a collision from the side.
The respective side airbag helps sup-
port the seat occupant's upper body.
For information on the correct sitting
posture, refer to page 44.
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.<

55
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 may 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 diffi-
cult 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 found 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 with the ignition key 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:
>The indicator lamp does not come on
or
>the indicator lamp lights up continu-
ously.
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 air-
bag system immediately.

Transporting children safelyCommercially available child-restraint
systems are designed to be secured
with a lap belt or with the lap belt por-
tion of a combination lap/shoulder belt.
Improperly or inadequately installed
restraint systems can increase the risk
of injury to children. Always read and
follow the instructions that come with
the system.Correct location for installingIn your BMW, all seats equipped with a
three-point safety belt – except for the
driver's seat – are suitable for installing
universal child-restraint systems of all
age classes and which have been
approved for the age group in question.
Child-restraint system with
tether strapIf you use a child-restraint system with
a tether strap, three additional tether
anchorage points have been provided.
To gain access to this anchor fitting lift
the plastic plug with the help of a
screwdriver.
Depending on the location selected for
seating in the rear passenger area,
attach the tether strap to the corre-
sponding anchorage point to secure the
child-restraint system, as shown in the
illustration.
If the respective seating position is fit-
ted with a head restraint lift the head
restraint and pass the tether strap
between the head restraint and the seat
back.
It is recommended to readjust the head
restraint in the lowest possible position.
Adjust the tether strap according to the
child-restraint manufacturer's instruc-
tions.

85 Technology 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 refer the problem to your
BMW center.
PDC does not remove the driver's
personal responsibility for evaluat-
ing the distance between the vehicle
and any objects. 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 ultrasonic measurement, as
occurs with tow bars and trailer cou-
plings, 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.<

Deactivating the DSC and the
DTCHold the DSC button down for at least
3 seconds. The indicator lamp and the
yellow brake warning lamp 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 acti-
vated whenever possible. cator lamp or the indicator lamps will go
out. DTC is deactivated.
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.
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.<

Hill Descent Control (HDC)*The 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 vehi-
cle speeds below approx. 22 mph /
35 km/h. When driving down steep
hills, the vehicle reduces speed auto-
matically down to about double walking
speed – approx. 7.5 mph / 12 km/h –
and then maintains this speed at a con-
stant.
You can use the accelerator or brakes
to vary this speed within a range from
approx. 3 mph / 5 km/h to approx.
15 mph / 25 km/h.
In conjunction with the multifunction
steering wheel you can use the +/–
button to set the cruise control to a tar-
get speed in the range from approx.
3 mph / 5 km/h to approx. 15 mph /
25 km/h.
HDC is automatically deactivated once
vehicle speed again exceeds approx.
37 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
37 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 malfunctionsSignaled 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 sys-
tem:
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 possi-
ble.

91
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 26 and cor-
rect them, if necessary
3. Initialize the system.
System limitations
The Flat Tire Monitor cannot pro-
vide you with advance warning of
sudden and severe tire damage caused
by external factors and does not detect
the balanced and very gradual pressure
loss that takes place in all four tires
over an extended period of time.<
On the other hand, the following situa-
tions can lead to a delayed detection of
pressure loss and even to the system
not functioning:
>Driving on snow-covered or slippery
roads
>Performance-oriented driving: slip at
the drive wheels, high levels of lateral
acceleration
>When driving with snow chains, false
warnings and undetected pressure
losses may occur
>When driving with a space-saver
spare tire, the Flat Tire Monitor can-
not function.
Initializing the system
Each time you correct the pres-
sure in a tire, or change a wheel or
tire, reinitialize the system immediately
afterwards. This requires a bit of driv-
ing.<
1. Before driving off, start the engine
but do not start driving
2. Press the button as long as you need
to until the yellow indicator lamp in
the instrument cluster lights up for a
few seconds
3. Drive off.
It takes a few minutes before the Flat
Tire Monitor can detect a flat tire and
issue a warning.
