PDC with visual warning
You also enjoy the option of having the sys-
tem show distances to objects on the Con-
trol Display. The Control Display will also
indicate the presence of objects in green
before they are close enough to generate a
signal tone.
Select "PDC pic." from the "Settings" menu
and confirm. This activates the PDC dis-
play.
The display then appears on the Control
Display whenever the PDC is automatically
or manually activated.
The previous display automatically
reappears after the system is deactivated.
Confirming the menu item takes
you back to the previous display.<
Limits of the system
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always
remains with the driver. Even when sensors
are involved, there is a blind spot in which
objects cannot be detected. The system is
also subject to the physical limits that apply
to all forms of ultrasonic measurement,
such as those encountered with tow bars and trailer couplings, as well as thin and
wedge-shaped objects, etc. Low objects
already displayed, e.g. a curb, can also dis-
appear from the detection area of the sen-
sors again before a continuous tone
sounds.
Loud noises from outside and inside the
vehicle may prevent you from hearing
PDC's signal tone.<
Keep the sensors clean and free of ice
or snow in order to ensure that they
will continue to operate effectively.
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/
ABS Antilock Brake System
The concept
ABS enhances active safety by preventing
the wheels from locking under braking.
ABS incorporates CBC and EBV.
In case of malfunction
If the indicator lamp lights up in
yellow, this indicates that ABS has
been deactivated in response to a
system malfunction. Conventional braking
efficiency remains available without limita-
tions. Please have the system inspected at
your BMW center.
CBC Cornering Brake Control
CBC is a supplement to ABS. It provides
further enhancements in vehicle stability
and steering response during lane changes
and cornering at high rates of lateral accel-
eration.
EBV Electronic brake-force
distribution
EBV controls the brake system's applica-
tion pressure at the rear wheels to ensure
stable deceleration.

Activating DTC
You may find it useful to briefly activate
DTC under the following special circum-
stances:
>When rocking the vehicle and starting
off in deep snow or on loose road sur-
faces
>When ascending snow-covered hills,
and when driving in deep or on hard-
packed snow
>When driving with snow chains.
Select "Settings". Select "DTC" and con-
firm. DTC is now activated. The DTC indi-
cator lamp in the Info Display lights up per-
manently.
When DTC is active, DSC provides
only limited system response up to a
speed of approx. 45 mph/70 km/h. Inter-
vention for stability enhancement is
reduced.<
Deactivating DTC again
Select "Settings". Select "DTC" and con-
firm. DTC is now deactivated. The DTC
indicator lamp in the Info Display goes out.
DSC is once again available without
restriction.
Switching off DSC
Select "Settings". Select "DSC" and con-
firm. DSC is deactivated. The indicator
lamp in the Info Display remains on contin-
uously.
Deactivating DSC automatically deacti-
vates DTC as well. The systems for
enhancing stability and traction are deacti-
vated, and there is no active braking inter-
vention or torque control.
A status report appears in the Check Con-
trol. Please take note of the additional
information on the Control Display.
To maintain optimized stability, drive
with the system on whenever possi-
ble.<
Reactivating DSC
Select "Settings". Select "DSC" and con-
firm. DSC is now activated. The indicator
lamp in the Info Display goes out.
The laws of physics cannot be
repealed, even with DSC. An appro-
priate driving style always remains the
responsibility of the driver. Avoid using the
additional safety margin provided by the
system as an excuse for taking unneces-
sary risks.
When DTC is active, DSC provides only
limited system response up to a speed of
approx. 45 mph/70 km/h. Intervention for
stability-enhancement is reduced.
Do not make any modifications to the DSC
system. Never allow anyone other than
authorized professional technicians to
carry out service or repairs on the DSC sys-
tem.<
DBC Dynamic Brake Control
When you apply the brakes rapidly, this
system automatically produces the maxi-
mum braking force boost and thus helps to
achieve the shortest possible braking dis-
tance during panic stops. This system
exploits all of the benefits provided by ABS.
Do not reduce the pressure on the brake
pedal for the duration of the brake applica-
tion. When the brake pedal is released, the
DBC is deactivated.

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 of one tire
drops significantly in relation to the pres-
sure of another tire.
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 page 189 and correct if neces-
sary
3.Initialize the system.
Limits of the system
The Flat Tire Monitor cannot indicate
sudden severe tire damage caused
by outside factors and does not detect a
natural, 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 the 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 "FTM" from the "Settings" menu
and confirm. The initialization menu
appears
3.Select "SET" and confirm
4.Drive off.
Status: "FTM is being initialized" is dis-
played.
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.

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
*
4Knee airbags for driver and front
passenger
Protective effect
The front airbags help protect the driver
and front passenger by responding to fron-
tal impacts in which safety belts alone
cannot 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 page 44.
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 side trim panels on the
front or rear 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.
If you note any indication of system mal-
function, if you desire to have an airbag
deactivated, or if the airbag retention sys-
tem is triggered in response to an accident,
you should always entrust all inspection,
repair and dismantling operations to your
BMW center.
Unprofessional attempts to service the sys-
tem could lead to failure in an emergency
or undesired airbag activation, either of
which could result in personal injury.
To ensure compliance with official safety
regulations, entrust disposal of airbag gen-
erators to a BMW center.<
Airbag warning information is also provided
on the sun visors.

Lamps
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 page 100.
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. You also have the options of
extending this period or, as an alternative,
having this function deactivated.<
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.
Following automatic activation, the
vehicle's external lighting remains on
when you switch on the 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.<
Adaptive Head Light*
The concept
Adaptive Head Light is a variable headlamp
control system that enables dynamic illumi-
nation of the road surface. Depending on
the steering angle and other assumptions,
the light from the headlamp follows the
course of the road.

Switching the interior lamps on and
off
Briefly press button 1.
If you want the interior lamps to remain off
continuously, maintain pressure on the but-
ton for approx. 3 seconds.
To revert to normal operation, briefly press
the button.
The button for the interior lamps in the rear
passenger area only switches these lamps
on and off.
Control of the footwell lamps, courtesy
lamps and ground lamps is also automatic.
Reading lamps
Reading lamps are provided in the front
and rear, adjacent to the interior lamps.
You can switch them on and off with
button 2 adjacent to each lamp.
To avoid discharging the battery, all
of the vehicle's interior lamps are
automatically extinguished approx. 15 min-
utes after the ignition is switched off.<
Light-emitting diodes LEDs
Light-emitting diodes installed behind
translucent lenses serve as the light source
for many of the controls and displays in
your vehicle. These light-emitting diodes,
which operate using a concept similar to
that applied in conventional lasers, are offi-
cially designated as Class 1 light-emitting
diodes.
Do not remove the covers, and never
stare into the unfiltered light for sev-
eral hours, as irritation of the iris could
result.<
