form accompanied by an indicator lamp
symbol. The alert is accompanied by a
gong.
Status reports warning of system malfunc-
tions are assigned one of two priority
ratings: Priority 1: These status messages and malfunction
reports are signaled by a gong. Simulta-
neous defects will be displayed consecu-
tively. These messages cannot be deleted,
and they remain in the display until the
problem is corrected. Supplementary infor-
mation also appears in the Control Display,
refer to Automatic messages in Control
Display. Priority 2: These status messages and malfunction
reports appear in the Info Display for
approx. 20 seconds.
Briefly press the CHECK button on the turn
signal indicator lever (see arrow) to cancel the message in the display (if allowed by
priority rating).
You can select stored status reports

It will not be possible to cancel the display
if the fuel level has fallen into the reserve
range or if a Check Control status report is

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).

83
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
Trip computer.
Average speed Periods with the vehicle parked and the
engine off are not included in the calcula-
tions of average speed. Time of arrival A display of your estimated time of arrival is
available whenever you enter a destination
in the navigation system, refer to page 126,
or enter the distance manually in the
computer, refer to page 84, prior to depar-
ture.
This function is only available if the
time in the Control Display has been
correctly set, refer to page 86.< Control Display screen contents You can activate the computer function at

Technology for comfort, convenience and safety

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.
