Fuel level display The fuel gauge mode appears automati-
cally once the fuel level falls into the
reserve range. The word "Reserve"
appears at the same time, indicating that
approx. 2.6 gallons (10 litres) of fuel remain
in the fuel tank.
It will not be possible to cancel the
onboard computer display once the
fuel level drops into the reserve range.
However, you can still request a display of
the cruising range. Computer, refer to
page 81.<
Tank capacity: approx. 19.4 gallons
(88 litres).
If the tilt of the vehicle varies (when you are
driving in mountainous areas, for example),
the needle may fluctuate slightly.
Always remember to refuel early:
attempts to continue driving to the
last drop can result in damage to the
engine and/or catalytic converter.< Cruising range Displays the estimated cruising range
available with the remaining fuel. The
system calculates the cruising range based
on operating conditions and the amount of
fuel remaining in the tank. The basis for the
calculations is the average fuel consump-
tion over the preceding 20 miles (30 km).

To avoid serious damage to the engine or
catalytic converter, always refuel as soon
as possible once your cruising range falls
to below 30 miles (50 kilometers).
When refueling you must add at least
approx. 1 1/3 gallons (5 litres) before the
computer will register the additional fuel. Distance to destination When you enter a destination in the naviga-
tion system or manually enter a distance in
the computer prior to departure, the
system can also display the distance
remaining to your destination, refer to
pages 126 and 84.
The system automatically adopts the
distance to your destination using the route
recommended by the navigation system.
When you enter a destination in the
navigation system, any manual
entries will be overwritten no later than
once 1640 feet (500 meters) of the calcu-
lated distance have elapsed.< Energy Control/
Current fuel consumption Shows your current fuel consumption rate
in mpg Ð in litres/100 km on Canadian vehi-
cles. This allows you to see whether your
current driving style is conducive to fuel
economy with minimum exhaust emis-
sions.
When the vehicle is stationary the display
goes to the maximum reading Ð zero on
Canadian models. Average fuel consumption The average fuel consumption is calculated
for the time during which the engine is
running.
You can use the Control Display to view
your fuel consumption rate over two
different distances, refer to Computer or

Technology for comfort, convenience
and safetyPDC Park Distance Control*

The concept The PDC assists you when you are parking.
Acoustic signals inform you of the distance
to an obstacle. Four ultrasonic sensors in
both the front and rear bumpers monitor
the distance to the nearest object. The
monitoring range of the front and two rear
corner sensors extends outward roughly
2 ft (60 cm), while the rear bumper's two
centrally located sensors detect objects at
distances of up to approximately 4.9 ft
(1.50 m). Automatic function Whenever the ignition is on the system
automatically assumes operational status
each time the selector lever is pressed
briefly in R. Manual activationPress the button, the indicator lamp lights
up.
The system is automatically deactivated
once the vehicle travels approximately
165 ft (50 m) or exceeds a speed of roughly
18 mph (roughly 30 km/h); the indicator
lamp goes out. You can reactivate the
system manually as needed.
Manual deactivation Press the button again; the indicator lamp
goes out. Acoustic signals The signal indicating the distance to the
nearest obstacle is directional. Thus, an
object detected to the left rear of the
vehicle will be indicated by a signal tone
from the left rear speaker, etc. As the
distance between vehicle and object
decreases, the intervals between the tones
become shorter. The signal tone becomes
continuous once the distance to the
nearest object falls to below roughly 1 ft
(30 cm).
The warning signal is canceled after
approximately 3 seconds when the
distance to an object remains constant
during this time (if you are moving parallel
to a wall, for instance). Malfunctions The indicator lamp within the button
flashes and a status message appears in
the Check Control panel.
Please take note of the supplementary
information provided in the Control Display.
Switch the system off and have the cause
of the malfunction corrected by your BMW
center. PDC with visual alert

You also enjoy the option of having the
system show distances to objects in the
Control 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 your selection. This activates
the PDC display.
The display then appears in the Control
Display whenever PDC is automatically or
manually activated.
The previous display automatically reap-
pears after the system is deactivated.
Confirm in the menu to return to
the previous display.<
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. After initial
detection, low objects such as curbs, etc.,
may disappear again before the system
starts to generate a continuous warning
tone. 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/
DSC Dynamic Stability
Control Your BMW is equipped with an extended
array of systems designed to enhance and
maintain vehicle stability under extreme
conditions. The following section describes
these functions based on DSC and ABS. The concept DSC maintains vehicle stability, even in
critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting from
a full stop, as well as optimizing traction.
The system recognizes any tendency for
the vehicle to assume an unstable attitude
such as oversteer or understeer; it then
counteracts this tendency with a combina-
tion of graduated reductions in engine
torque and selective braking intervention at
individual wheels. DSC provides optimal
stability within the limits defined by the
laws of physics.
The DSC is operational every time you start
the engine. DSC includes the functionality
of the DTC Dynamic Traction Control and
DBC Dynamic Brake Control.
With its selective braking intervention at the
individual drive wheels, DTC fulfills the
same function as a conventional limited-
slip differential to enhance traction under
difficult driving conditions, such as on
snow, etc. Indicator lamps
The indicator lamp in the Info
Display goes out soon after you
start the engine.
If the indicator lamp flashes:
DSC controls the drive and braking forces.
The indicator lamp stays lit:
DSC has been switched off via the Control
Display.

Technology for comfort, convenience and safety
90 The indicator lamp and the brake
warning lamp remain on continu-
ously:
DSC, DTC and DBC have been
deactivated or a system malfunc-
tion is present.
When the system is off, the stability main-
tenance functions described above are no
longer available. The vehicle will remain
completely operational, however, without
DSC.
Please respond to any malfunctions by
referring the problem to your BMW center.

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.

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.<

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

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.
