Activating DTC Dynamic Traction
Control 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 surfaces
>When ascending snow-covered hills,
and when driving in deep or on hard-
packed snow
>When driving with snow chains.
Select the "Settings" menu. Select "DTC"
and confirm your entry. DTC is now acti-
vated. The "DTC" indicator lamp in the
Control Display lights up.
When DTC is operating, DSC is
restricted to limited functionality up
to vehicle speeds of approx. 45 mph (70 km/h). Control intervention to maintain
stability is reduced.<
To deactivate DTC again Select the "Settings" menu. Select "DTC"
and confirm your entry. DTC is now deacti-
vated. The "DTC" indicator lamp in the Info
Display goes out. To deactivate DSC Select the "Settings" menu. Select "DSC"
and confirm your entry. DSC is deactivated.
The indicator lamp in the Info Display
remains on continuously.
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
Control panel. Please take note of the addi-
tional information in the Control Display
panel.
To maintain optimal stability, drive
with the system on whenever
possible.< To reactivate DSC Select the "Settings" menu. Select "DSC"
and confirm your entry. DSC is now on. 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repealed, even with DSC.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 modiÞcations to the DSC system.
Never allow anyone other than authorized
professional technicians to carry out
service or repairs on the DSC system.< Dynamic Brake Control DBC

When you apply the brakes rapidly, this
system automatically produces the
maximum braking force boost and thus
helps to achieve the shortest possible
braking distance 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.
In the event of a malfunction, the
warning lamp comes on with a
yellow lamp. Have the system
checked and repaired at your BMW center
as soon as possible.
Check Control messages, refer to page 80.
Please note the supplementary information
provided in the Control Display.
Warning lamp on Canadian models.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.
Cornering Brake Control CBC CBC is a technical advance based on ABS.
It provides further enhancements in vehicle
stability and steering response during lane
changes and cornering at high rates of
lateral acceleration. EBV Electronic brake-force
distribution EBV controls the brake system's applica-
tion pressure at the rear wheels to ensure
stable deceleration. In case of malfunction
If the brake system warning lamp
lights up in red, appearing together
with the yellow lamps for ABS and
DSC: the stability control is no
longer operational.
If all three lamps light up in yellow:
malfunction in the stability control
systems.
While you may continue, you should
remember to proceed cautiously and drive
defensively while avoiding full brake appli-
cations.
Please have the system checked at the
nearest BMW center.
Check Control status messages, refer to
page 80. Please note the supplementary
information provided in the Control Display.

Dynamic Drive The concept Dynamic Drive minimizes body roll and
optimizes vehicle stability during cornering
and evasive maneuvers.

Technology for comfort, convenience and safety
92 Active stabilizers at the front and rear axles
form the basis for Dynamic Drive. Suspen-
sion compliance adapts to suit driving
conditions, 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
continuously runs through closed-loop
control cycles lasting only fractions of a
second. In case of malfunction
The symbol will light up, accompa-
nied by a status message in the
Check Control panel. Please take
note of the additional information in the
Control Display panel.
You can find more detailed information on
the Check Control starting on page 80.
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
tendency to tilt during cornering and in
crosswinds.
If a status message appears in the Check
Control panel, accompanied by a red
symbol, the hydraulic fluid in the reservoir
may have fallen to below the minimum
level, possibly owing to leakage in the
hydraulic system. Stop the vehicle and
switch off the engine immediately.
Please observe the additional instructions
provided in the Control Display panel.<
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.Comfort program The system automatically assumes opera-
tion in its Comfort mode each time you start
the engine; this mode is suitable for use
throughout the vehicle's entire speed range
and regardless of load. Sport programActivate in "Settings" menu with the igni-
tion on.
You should select the Sport program for
consistently performance-oriented
response from shock absorbers and
steering. RDC Tire Pressure Monitor*The conceptRDC monitors inflation pressures in all four
tires while you drive. The system provides
an alert whenever the inflation pressure
drops significantly below the specified
pressure in one or more tires.
To initialize RDC, start by checking the
inflation pressures in all four tires and
comparing them with those specified in the
chart on page 171, correcting them as
necessary. Then proceed to initialize the
system.

Technology for comfort, convenience and safety
94
In the event of loss in tire pressure If the indicator lamp symbol in the Check
Control lights up in yellow, and a message
also appears, this indicates that the infla-
tion pressures in the tires have fallen to
below the specified level, which is normal
in every tire after a certain amount of time.
This alerts you to have the tires inflated to
the specified pressures as soon as
possible.
Please take note of the additional informa-
tion in the Control Display panel.
If you are prompted to check the tire
pressure shortly after a correction has
been made, this indicates that the
corrected values were not accurate. Please
check the inflation pressure again and
make corrections according to the inflation
pressure table. Then reinitialize the
system.< Flat tire If you have a flat tire, the indicator lamp
symbol in the Check Control will light up in
red, and a message will appear. In addition,
a gong sounds.
If this occurs, reduce vehicle speed imme-
diately and stop the vehicle. Avoid hard
and sudden steering and braking maneu-
vers. Replace the damaged tire.
The spare tire provided with your
vehicle is equipped with the elec-
tronics required to support RDC operation;
once the spare tire is installed, the pressure
in this tire will also be monitored following
system initialization.
Have the tires changed at your BMW
center. Your BMW center has the informa-
tion needed for working with RDC and is
equipped with the necessary special
tools. radio frequency as RDC can generate inter-
ference signals that may prevent the
system from operating as intended. The symbol will appear in yellow in the
Check Control panel and a message will
appear.
You will also see the same message
>in the event of a system fault
>if a wheel is mounted without the
appropriate electronics
>if, in addition to the spare tire, additional
wheels with RDC electronics are on board.
Please refer to the additional information
supplied in the Control Display, and have
the system inspected at your BMW center.
Self-leveling suspension*

In the event of malfunction
A Check Control message
appearing together with this symbol
indicates a malfunction in the self-
leveling suspension. Please take note of
the additional information in the Control
Display panel.
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, you should respond by immedi-
ately proceeding to the nearest BMW
center. Drive with appropriate caution in
the meantime. 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.
Adaptive brake lamp The adaptive brake lamp 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 assemblies
and the high-mount brake lamp on the rear
tray light up during braking.
>Heavy braking and braking with ABS:
The tail lamps also light up with the same
intensity as the standard brake lamp units
to enhance the warning effect of the brake
lamps.

With the switch in this position, the
front, rear and side vehicle lighting
is switched on. You can use the side
marker lamps for parking. For lighting on
one side for parking as an additional
feature, refer to page 97.
Low beams
When you switch off the ignition
with the headlamps on, the head-
lamps go out, and only the parking
lamps remain on.
"Follow me home" lamps:
After parking the vehicle and
switching off the headlamps, you can use
the headlamp flasher control to activate the
headlamps (low beam) for a period of
roughly 40 seconds. You also have the
options of extending this period or, as an
alternative, having this function deacti-
vated.<
"Lamps on" warning If you switch off the ignition while the head-
lamps are on, when you subsequently open
the driver's door a buzzer will sound for
several seconds, while the Check Control
will provide you with an additional reminder
in the form of a message alerting you to the
fact that the headlamps have not been
switched off
.
Daytime driving lamps
*
If you wish, you can leave the light switch in
the low-beam position:
All external lamps go out when you switch
off the ignition.
Always observe all applicable laws
governing 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 the headlamps on and off
(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 illuminated 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
cannot serve as a substitute for your
personal judgment in determining when the
lamps should be switched on in response
to ambient lighting conditions. For
example, the system cannot detect fog. To
avoid safety risks, you should always
switch on the lamps manually under these
conditions.<
You can have the sensitivity of the
headlamp control system adjusted on
your vehicle.<

Light-emitting diodes Ð 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 an
extended period (several hours), as irrita-
tion of the iris could result.<
