Have the system checked as soon as pos-
sible.
Display of the previously described
malfunction on Canadian models.
Dynamic Drive
The concept
Dynamic Drive minimizes body roll and
optimizes vehicle stability during cornering
and evasive maneuvers.
Active stabilizers at the front and rear axles
form the basis for Dynamic Drive. Suspen-
sion compliance adapts to suit driving con-
ditions, varying from performance-oriented
during cornering to smooth and comfort-
oriented when the vehicle is proceeding in
a straight line.
The system assumes operational status
each time you start the engine.
Driving with Dynamic Drive
During vehicle operation, the system con-
tinuously runs through closed-loop control
cycles lasting only fractions of a second.
Malfunction
The warning lamp lights up, accom-
panied by a status message in the
Check Control. Please take note of
the additional information on the Control
Display. A malfunction has occurred in the
system. Have the system checked as soon
as possible.
If the Dynamic Drive system switches
off in response to malfunction, please
remember to adapt your speed accord-
ingly, especially in curves.
The suspension will be noticeably softer
and the vehicle will display a greater ten-
dency to tilt during cornering and in cross-
winds.
If a Check Control message stating that you
should stop appears in addition to the red
symbol, stop immediately and switch off
the engine. In this case the oil level in the
reservoir may have dropped below the min-imum, possibly owing to a leak in the
hydraulic system.
Please observe the additional instructions
provided on the Control Display.<
EDC Electronic Damping
Control*
The suspension responds to changes in
factors such as road surface, or operating
conditions such as steering and braking, by
adapting to the new conditions within frac-
tions of a second.
Two programs are available; they can be
selected in the "Settings" menu.
Comfort mode
The Comfort mode is suitable for use
throughout the vehicle's entire speed range
and regardless of load.
Sport program
You should select the Sport program for
consistently performance-oriented
response from shock absorbers and steer-
ing.
Flat Tire Monitor
The concept
The Flat Tire Monitor keeps track of the
inflation pressures in the four fitted tires as
you drive. The system provides an alert
whenever the inflation pressure drops sig-
nificantly in relation to the pressure another
tire.

Technology for comfort, convenience and safety
96 The check of the tire inflation pressure is
based on monitoring the relative speeds of
the wheels. A flat tire is detected and
reported on the basis of a deviation in cer-
tain speed ratios.
Functional requirements
So that the Flat Tire Monitor can learn the
correct inflation pressure, please perform
the following:
1.Check the inflation pressures in all tires
2.Compare with the inflation pressure
table on page189 and correct if neces-
sary
3.Initialize the system.
System limits
The Flat Tire Monitor cannot indicate
sudden severe tire damage caused by
outside factors and does not detect a natu-
ral, even pressure drop in all four tires.<
In the following situations, on the other
hand, there can be delays in detecting tire
pressure losses, and even system failure:
>When you are driving on snow-covered
or slippery road surfaces
>In the case of performance-oriented
driving: slip on the drive wheels, high
lateral acceleration
>False alarms and undetected loss of
pressure may occur when you are driv-
ing with snow chains fitted.
Initializing system
Perform the initialization immediately
after correcting the inflation pressure,
changing a tire or changing a wheel or all
wheels. A drive is necessary for this pur-
pose.<
1.Start the engine, but do not drive off
2.Select "RPA" from the "Settings" menu
and confirm your selection. The initial-
ization menu appears 3.Select "SET" and confirm your selection
4.Drive off.
"FTM is being initialized" is displayed as the
status.
It takes at least 10 minutes before the Flat
Tire Monitor can detect and report a flat
tire.
When driving with snow chains, do
not initialize the system.<
Select and confirm to exit from the
menu.
Indication of a flat tire
The warning lamp lights up red,
accompanied by a status message
in the Check Control. In addition, an
acoustic signal sounds. A flat tire or a major
air loss has occurred.
1.Reduce speed and stop the vehicle
carefully. Avoid sudden braking and
steering maneuvers
2.Identify damaged tire
If identification is not possible,
contact your BMW center.<
3.Replace the damaged tire, refer to
Changing wheels on page204.

Vehicles with run-flat tires:
1.Cautiously reduce the vehicle speed to
below 50 mph/80 km/h. Avoid sudden
braking and steering maneuvers. Do not
exceed a vehicle speed of 50 mph/80
km/h
Due to the reinforcement on the
side walls of the run-flat tires,
inflation pressure loss can not usually
be recognized from the outside, refer to
Run-flat tires on page206.<
2.To continue driving, comply with the
instructions for driving with damaged
tires on page206.
Malfunction
The indicator lamp lights up yellow,
accompanied by a status message
in the Check Control. The Flat Tire
Monitor has malfunctioned or failed. Have
the system checked as soon as possible.
Self-leveling suspension*
Malfunction
A Check Control message appear-
ing together with this symbol indi-
cates a malfunction in the self-level-
ing suspension. Please take note of the
additional information on the Control Dis-
play.
Stop and inspect the vehicle. If the rear of
the vehicle is visibly lower than the front,
possibly accompanied by a tilt noticeable
when you compare the left rear with the
right rear, please respond by immediately
proceeding to the nearest BMW center.
Drive with appropriate caution in the mean-
time. The vehicle has reduced ground
clearance and driving comfort may be
noticeably reduced. Even if the attitude of
the vehicle is normal, you should consult
the nearest BMW center if the warning
lamp indicates a system fault.
Brake Force Display
The Brake Force Display indicates the
intensity with which you are applying your
brakes to drivers of following vehicles.
The display consists of two stages:
>Normal braking:
The brake lamps in the tail lamp assem-
blies and the high-mount brake lamp on
the rear tray light up during braking
>Heavy braking and braking with ABS:
The rear lamps also light up with the
same intensity as the standard brake
lamp units to enhance the warning
effect of the brake lamps.

Airbags
The following airbags are located under the
marked covers:
1Front airbags for driver and front pas-
senger
2Head airbags in front and rear
3Side airbags in front and rear
*
4Knee airbags for driver and front pas-
senger
Protective effect
The front airbags help protect the driver
and front passenger by responding to fron-
tal impacts in which safety belts alone can-
not provide adequate restraint. When
needed, the head and side airbags help
provide protection in the event of side
impact. The side airbags help restrain the
side of the occupant's upper torso, and the
head airbags help support the head while
also helping provide protection against any
objects penetrating into the passenger
compartment. The knee airbags help pro-
tect the legs against impact against the
cockpit.
The airbags are deliberately not triggered in
every impact situation, e.g. less severe
accidents, 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 open-
ing 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. tion, refer to page46.
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 reten-
tion system from the vehicle. Never modify
or tamper with either the wiring or the indi-
vidual components in the airbag system.
This category includes the upholstery in the
center of the steering wheel, on the instru-
ment panel, the doors and the roof pillars
along with the sides of the headliner. Do
not attempt to remove or dismantle the
steering wheel.
Do not touch the individual components
directly after the system has been trig-
gered, because there is a danger of burns.
In case of malfunctions, storage or after the
airbag restraint system has been triggered,
only have checking, repair or dismantling
and the scrapping of the airbag generators
carried out by a BMW center or a workshop
that uses personnel trained in accordance
with BMW requirements and equipped with
the required explosives permits. Unprofes-
sional attempts to service the system could
lead to failure in an emergency or undes-
ired airbag activation, either of which could
result in personal 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‘s 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 automat-
ically deactivated on the passenger's
side
>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 per-
sons that the front passenger airbags are
deactivated.
The state of the front passenger airbags is
shown with the indicator lamp, refer to Indi-
cator lamps in the following. In this case
transport the corresponding persons on the
rear seat.
Except when persons to be transported, do
not increase the load on the front passen-
ger seat with additional items. Do not fit
seat covers, seat cushion padding, ball
mats or other items to the front passenger
seat unless they are specifically recom-
mended by BMW. Do not place any items
under the seat. Otherwise, the function of
the seat occupation detection could be
impaired.<
Indicator lamps
Airbag system ready for use
The warning lamp indicates the operational
readiness of the entire airbag system and
the safety belt tensioners from the radio position: the warning lamp goes out after
afew seconds.
The indicator lamp above the interior rear-
view mirror indicates whether the front-pas-
senger airbag system is activated or deacti-
vated as of ignition key radio position.
The indicator lamp refers exclusively
to the front-passenger airbag sys-
tem.<
>The indicator lamp goes out after a few
seconds.
The front passenger airbags are active,
e.g. when transporting an adult
>The indicator lamp lights up continu-
ously. The front passenger airbags are
deactivated, e.g. when transporting a
child in the child-restraint system or
when the seat is unoccupied.
For more information on the operating prin-
ciple of the front passenger airbag system
and seat occupation detection, refer to
Automatic deactivation of the front passen-
ger airbags.
Airbag system malfunction
Have the airbag system checked
immediately if a malfunction occurs,
as otherwise there is a danger of the sys-
tem failing to respond in the expected man-
ner to an impact occurring within its normal
response range.<
A fault has occurred in the airbag
system:
>The warning lamp fails to come on as of
ignition radio mode
>Warning lamp lights up continuously
>Warning lamp lights during driving.

Parking lamps/low beams
Parking lamps
With the switch in this position, the
front, rear and side vehicle lighting
is switched on. You can use the
parking lamps for parking. For lighting on
one side for parking as an additional fea-
ture, refer to page101.
Low beams
When you switch off the ignition
with the headlamps on, the head-
lamps go out, and only the parking
lamps remain on.
Pathway lighting
After parking the vehicle and switch-
ing off the headlamps, you can use
the headlamp flasher control to activate
the low beams for a period of roughly
40 seconds. Pressing the button 4 on the
remote control, refer to page 36, also
switches on the low beams for approx.
40 seconds. In addition, the door handle
and interior lamps are switched on for
approx. 10 seconds.
You can have the lighting up of the low
beams extended or the function deacti-
vated.<
Lights on warning
If you switch off the ignition while the head-
lamps are on, when you subsequently open
the driver's door a gong will sound for sev-
eral seconds, while the Check Control will
provide you with a message
.
Daytime driving lamps*
If you wish, you can leave the light switch in
the low-beam position.
Always observe all applicable laws govern-
ing the use of daytime driving lamps.
You can switch on the parking lamps when
needed using the standard procedure
described under Parking lamps.
You can have the daytime driving
lamps on your vehicle programmed
to operate as desired.<
Automatic headlamp control
When you set the switch to this
position, the system activates and
switches on and off the low beams
in response to changes in ambient light
conditions, for instance, in tunnels, at dawn
and dusk, and in rain and snow. The green
indicator lamp next to the symbol is illumi-
nated when the low beams are on.
The low beams remain switched on
regardless of the ambient light when
you switch on the front fog lamps.<
The automatic headlamp control can-
not serve as a substitute for your per-
sonal judgment in determining when the
lamps should be switched on in response
to ambient lighting conditions. For exam-
ple, the system cannot detect fog. To avoid
safety risks, you should always switch on
the lamps manually under these condi-
tions.<
You can have the sensitivity of the
headlamp control system adjusted on
your vehicle.<
