Canadian models.
DTC Dynamic Traction Control
In special driving states, e.g. in deep snow,
DTC ensures maximum forward momen-
tum. The gain in forward momentum also
involves a reduction in driving stability.
DTC is active up to 45 mph/70 km/h.
Activating DTC
Press the DSC button briefly; the
DTC indicator lamp in the instru-
ment cluster lights up permanently.
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.
When DTC is active, DSC provides
only limited system response up to a
speed of approx. 45 mph/70 km/h. Control
intervention for stability-enhancement is
reduced.<
Deactivating DTC again
Press the DSC button again; the DTC indi-
cator lamp in the instrument cluster goes
out. DSC is available once again without
restriction.
Deactivating DSC
Press the DSC button for at least 3 sec-
onds; the DSC indicator lamp in the instru-
ment cluster lights up permanently. DSC is
deactivated.
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 message appears on the Control Display.
Please note any supplementary information
that appears there.
To maintain optimal stability, drive
with the system on whenever possi-
ble.<
Reactivating DSC
Press the DSC button again briefly; the
indicator lamp in the instrument cluster
goes out. DSC is now activated.
The laws of physics cannot be
repealed, even with DSC. An appro-
priate driving style always remains the
responsibility of the driver. Therefore, do
not reduce the additional safety margin
again by taking risks.
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-

Technology for comfort, convenience and safety
80 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,
DBC is deactivated.
In the event of a malfunction, the
warning lamp in the instrument
cluster lights up yellow.
Have the system checked and repaired at
your BMW center as soon as possible.
Please note any information that appears
on the Control Display.
Warning lamp for Canadian models.
Active roll stabilization*
The concept
Active roll stabilization minimizes body roll
and optimizes vehicle stability during cor-
nering and evasive maneuvers.
Dynamic stabilizers at the front and rear
axles form the basis for active roll stabiliza-
tion. Suspension compliance adapts to suit
driving conditions, varying from perfor-
mance-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 active roll stabilization
During vehicle operation, the system con-
tinuously runs through closed-loop control
cycles lasting only fractions of a second.
In case of malfunction
The symbol in the instrument clus-
ter lights up and a message
appears on the Control Display.
Please note any supplementary information
that appears there.
You can find more information on the
Check Control starting on page 68. If the active roll stabilization system is
deactivated in response to malfunc-
tion, please remember to adapt your speed
accordingly, 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 message stating that you should stop
appears on the Control Display 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 minimum, possibly owing to a
leak in the hydraulic system.
Please note any supplementary information
that appears on the Control Display.<
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 in
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 requirement
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 170 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

Technology for comfort, convenience and safety
84 >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 telltale 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
Operational readiness of airbag
system
The airbag indicator lamp in the instrument
cluster indicates the operational readiness
of the entire airbag system and the safety
belt tensioners as of ignition key position 1.
The indicator lamp goes out after a few
seconds.The telltale lamp above the interior rear-
view mirror indicates whether the front-
passenger airbag system is activated or
deactivated as of ignition key position 1.
The telltale lamp refers exclusively to
the front-passenger airbag system.<
>The telltale lamp goes out after a few
seconds.
The front passenger airbags are active,
e.g. when transporting an adult
>The telltale lamp lights up continuously.
The front passenger airbags are deacti-
vated, 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
A system malfunction could prevent
the system from responding in the
expected manner to an impact occurring
within its normal response range.
Please have the airbag system inspected
immediately at a BMW center.<
There is a fault in the airbag system
if the airbag indicator lamp in the
instrument cluster behaves as fol-
lows:
>Indicator lamp does not light up as of
ignition key position 1
>It remains on continuously
>Indicator lamp lights up while the vehi-
cle is being driven.

Fog lamps
Always observe all applicable laws govern-
ing the use of fog lamps.
To disconnect, briefly press the button
again.
The parking lamps or low beams
must be switched on for the fog
lamps to operate. The green indica-
tor lamp in the instrument cluster lights up
whenever the fog lamps are on.
The fog lamps are switched off whenever
the high beams are switched on.
If the automatic headlamp control is
activated, the low beams will come on
automatically when you switch on the fog
lamps.<
Interior lamps
The interior lamps operate automatically.
Switching the interior lamps on
and off manually
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, press the
button briefly.
Control of the footwell lamps, door entry
lighting and courtesy lamps
* is also auto-
matic.
Reading lamps
Reading lamps are provided in the front
and rear adjacent to the interior lamps. You
can switch them on and off using the
buttons 2 located next to the lamps.
To avoid discharging the battery, all of
the vehicle's interior lamps are auto-
matically switched off approx. 15 minutes
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 several
hours, as irritation of the retina could
result.<

Front ventilation
You can adjust the vent outlets for the
upper body to suit your personal require-
ments.
You can use the serrated dials 1 to open
and close the vent outlets through an infi-
nitely-variable range, while the levers 2
allow you to adjust the airflow direction.
Ventilation for cooling
Adjust the vent outlets to direct the flow of
cool air in your direction, for instance, if the
interior has become too warm, etc.
Draft-free ventilation
Set the vent outlets so that the air flows
past you and is not directed straight at you.
You can also individually adjust the air tem-
perature of the vent outlets for the upper
body area using the Control Center.
Rear ventilation
The serrated dial 1 allows you to open and
close the vents through an infinitely-vari-
able range.
Serrated dial 2:
Turn towards blue: colder.
Turn towards red: warmer. You can adjust the airflow direction using
the levers 3.
Independent ventilation*
The independent ventilation blows air into
the passenger compartment to lower inte-
rior temperatures.
System operation is controlled using the
Control Center. You can set two different
times for the system to start.
The system remains on for 30 minutes. It
can also be switched on and off directly.
Since the system uses a substantial
amount of electrical current, you should
refrain from activating it twice in succes-
sion without allowing the battery to be
recharged in normal operation between
use.
The independent ventilation system is
available for preprogrammed operation at
outside temperatures above approx. 597/
156 and for direct activation at any tem-
perature, but is not operational when the
vehicle is underway.
The air enters the passenger compartment
through the vent outlets in the instrument
cluster, which can be adjusted for both
direction and airflow. These vent outlets
must be open for the system to operate.
