System limits
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always remains
with the driver. Even when sensors are pro-
vided, there is a blind spot in which objects can
no longer be detected.The system is also sub-
ject to the physical limits that apply to all forms
of ultrasonic measurement, such as those
encountered with thin and wedge-shaped
objects, etc. Low objects already displayed, e. g. a curb, can also disappear from the detec-
tion area of the sensors again before a continu-
ous tone sounds. Loud noises from outside and
inside your vehicle may prevent you from hear-
ing the PDC signal tone.<
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Keep the spray at least 4 in/10 cm away from
the sensors.<
Driving stability control
systems
Your BMW is equipped with an extended array
of systems designed to enhance and maintain
vehicle stability under extreme conditions.
ABS Antilock Brake System
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
The ABS is operational every time you start the
engine. Safe braking, refer to page107.
CBC Cornering Brake Control
When braking during curves or when braking
during a gear change, driving stability and
steering response are improved further.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
DBC Dynamic Brake Control
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. This system exploits all of the benefits pro-
vided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the brake application. When
the brake pedal is released, DBC is deactivated.

Malfunction in vehicle stability-control
systems
The brake system warning lamp lights
up in red, appearing together with the
indicator lamps for ABS and DSC. A
message appears on the Control Dis-
play. The driving stability control sys-
tems are deactivated. Conventional
braking efficiency remains available
without limitations. While you may con-
tinue, you should remember to proceed cau-
tiously and drive defensively while avoiding full
brake applications. Have the system checked
as soon as possible.

malfunction on Canadian models.
The indicator lamp for DSC lights up; a
message appears on the Control Dis-
play. DSC and DTC are deactivated.
The stability maintenance functions are no
longer available. The vehicle remains in running
order. Have the system checked as soon as
possible.
The warning lamp for the brake system
lights up in yellow; a message appears
on the Control Display. DBC has failed.
Have the system checked as soon as possible.

malfunction on Canadian models.
Active roll stabilization*
The concept
Active roll stabilization minimizes body roll and
optimizes vehicle stability during cornering and
evasive maneuvers.
Dynamic stabilizers at the front and rear axles
form the basis for active roll stabilization. Sus-
pension compliance adapts to suit driving con-
ditions, varying from performance-oriented during cornering to smooth and comfort-ori-
ented when the vehicle is proceeding in a
straight line. During vehicle operation, the sys-
tem continuously runs through closed-loop
control cycles lasting only fractions of a second.
The system assumes operational status each
time you start the engine.
Malfunction
The warning lamp lights up and a mes-
sage appears on the Control Display.
There is a malfunction in the system.
Have the system checked as soon as possible.
If there is a malfunction in the system,
please remember to adapt your speed
accordingly, especially in curves. The suspen-
s i o n w il l b e n o t i c ea b ly s o f t e r a n d t h e v e h i cl e w il l
display a greater tendency to tilt during corner-
ing and in crosswinds. If a message stating that
you should stop appears on the Control Display,
stop and switch off the engine as soon as pos-
sible. In this case the oil level in the reservoir
may have dropped below the minimum, possi-
bly owing to a leak in the hydraulic system. Do
not continue driving. Contact your BMW cen-
ter.<
Flat Tire Monitor
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the four mounted tires as you
drive. The system provides an alert whenever
the inflation pressure drops significantly in rela-
tion to the pressure in another tire.
In the event of a pressure loss, the rolling radius
and therefore the rotation speed of the wheels
change. This change is detected and is
reported as a flat tire.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.
Perform the initialization immediately
after correcting the inflation pressure,

2.At the next opportunity, check the air pres-
sure in all four tires.
If the tire inflation pressure in all four
tires is correct, the Flat Tire Monitor
has not been initialized. The system must
then be initialized.<
3.In the event of complete tire pressure loss,
0 psi/0 kPa, or obvious tire damage, you can
estimate the possible distance for contin-
ued driving on the basis of the following
guide values:
>With a light load:
1 to 2 persons without luggage:
approx. 155 miles/250 km
>With a medium load:
2 persons, luggage compartment full, or
4 persons without luggage:
approx. 94 miles/150 km
>With a full load:
4 or more persons, luggage compart-
ment full:
approx. 30 miles/50 km
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. In the event of
pressure loss, vehicle handling changes. This
includes reduced tracking stability in braking,
extended braking distance and altered natural
steering characteristics.
If unusual vibrations occur while the vehicle is
being driven, this can indicate final failure of the
damaged tire. Reduce speed and stop as soon
as possible. Do not continue driving. Contact
your BMW center.<
Malfunction
The warning lamp lights up yellow and
a message appears on the Control Dis-
play. The Flat Tire Monitor has a mal-
function or has failed. Have the system checked
as soon as possible.
Active steering*
The concept
The active steering is a system that actively var-
ies the steering angle of the front wheels in rela-
tion to the steering wheel movements.
When you are driving in the low road speed
range, e. g. in a town or when parking, the steer-
ing angle increases, i.e. the steering becomes
very direct. In the higher speed range, on the
other hand, the steering angle is reduced more
and more. This improves the handling capability
of your BMW over the entire speed range.
In critical situations, the system can make tar-
geted corrections to the steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes. This stabilizing
intervention is simultaneously deactivated
when DSC is switched off, refer to page78.
Malfunction
The warning lamp lights up. The active
steering is no longer operational. At low
speeds, greater steering wheel move-
ments are required, whereas at higher speeds,
the vehicle reacts more sensitively to steering
wheel movements. Have the system checked.
If the warning lamp lights up during the first
engine starting following a power supply inter-
ruption, the system must be activated by being
initialized.
Initializing system
1.Start the engine.
2.With the vehicle stationary, turn the steer-
ing wheel from the straight-ahead position
t o t h e le f t a s f a r a s i t w i ll g o a n d t h e n b a c k t o
the straight-ahead position.
3.Switch off the engine.
When you start the engine again, all the func-
tions of the active steering are available once
again.

Airbags
The following airbags are located under the
marked covers:
1Front airbags for driver and front passenger
2Head airbags in front and rear
3Side airbags in front and rear
Protective action
To ensure that the safety systems con-
tinue to provide optimized protection,
please observe the adjustment instructions on
page38.<
The front airbags help protect the driver and
front passenger by responding to frontal
impacts in which safety belts alone cannot pro-
vide adequate restraint. When needed, the
head and side airbags help provide protection in
the event of side impact. The relevant side air-
bag supports the side upper body area. The
head air bag supports the head.
The airbags are deliberately not triggered in
every impact situation, e. g. less severe acci-
dents, certain roll-over conditions, or rear-end
collisions.
The rear seat side airbags may already
have been deactivated by a BMW center.
Labels in the rear door opening should indicate
the status of your rear seat side airbags. If you
are uncertain of their status, or wish to have the
airbags activated or deactivated, please contact
your BMW center.<
For information on the correct sitting position,
refer to page38.
Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way. Do not attempt to remove the airbag retention system from the
vehicle. Never modify or tamper with either the
wiring or the individual components in the air-
bag system. This category includes the uphol-
stery in the center of the steering wheel, on the
instrument panel, the side trim panels on the
doors and the roof pillars along with the sides of
the headliner. Do not attempt to remove or dis-
mantle the steering wheel. Do not touch the
individual components immediately after the
system has been triggered, because there is a
danger of burns. In the event of malfunctions,
deactivation, or triggering of the airbag restraint
system, have the testing, repair, removal, and
disposal of airbag generators executed only
by a BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel and has the
required explosives licenses. Unprofessional
attempts to service the system could lead to
failure in an emergency or undesired airbag
activation, either of which could result in per-
sonal injury.<
Airbag warning information is also provided on
the sun visors.
Automatic deactivation of front
passenger airbags
Your BMW has a seat occupation detection
system. By evaluating the weight on the front
passenger seat, the system detects whether or
not the seat is occupied by a child in the child-
restraint system or an adult.
>When a child is seated in the child-restraint
system or with an empty seat, the front and
side airbags are automatically deactivated
on the passenger side.

Technology for comfort, convenience and safety
84 >When an adult is traveling in the front seat,
the front and side airbags remain active on
the passenger side.
Although not desired, it can occur in the
case of heavier children that the front
passenger airbags remain active or in the case
of very light adults or young persons that the
front passenger airbags are deactivated. In
these cases, have the person ride in the rear
seat, refer to Passenger airbag status lamp
below. Do not load the passenger seat with any
items in addition to the person to be trans-
ported. Do not fit seat covers, seat cushion pad-
ding, ball mats or other items onto the front pas-
senger seat unless they are specifically
r e c o m m e n d e d b y B M W . D o n o t p l a c e a n y i t e m s
under the seat. Otherwise, the function of the
seat occupation detection could be impaired.<
Operational readiness of airbag system
As of ignition key position of 1, the warning
lamp lights up briefly, thus indicating the opera-
tional readiness of the entire airbag system and
the safety belt tensioners.
Airbag system malfunction
>The warning lamp does not light up as of
ignition key position 1.
>Warning lamp lights up continuously.
A malfunction could prevent the airbag
system from responding in the expected
manner to an impact occurring within its normal
response range.<
Passenger airbag status lamp
The indicator lamp located above the rear view
mirror indicates whether the front passenger
airbag system is active or not active/OFF.
The indicator lamp is used only for the
front passenger airbag system. The indi-
cator lamp illuminates to show that the front
passenger airbag system is OFF/not active.<
>The lamp illuminates briefly during startup,
but then goes out if the seat is empty, or an
adult or child of sufficient size is detected.
>The lamp remains illuminated when a child
in a rear facing child-restraint system is
detected and indicates that the passenger
airbag system is off.
If the lamp is illuminated when the seat is
occupied by a very light adult or teenager,
it is recommended that the person sit in the
rear.<
