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
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
any time by selecting it from the "OB data"
menu.

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
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.

reason you should ensure that these
outlets are open before selecting this
program.
Outside air/AUC Automatic recircu-
lated-air control/Recirculated air
You can respond to unpleasant
odors or pollutants in the imme-
diate environment by tempo-
rarily suspending the flow of outside air.
The system then recirculates the air
currently within the vehicle. AUC executes
this function automatically.
Press the button repeatedly to run through
the following control sequence:
>Indicator lamps off: outside air flows into
the vehicle
>Left-hand indicator lamp on Ð AUC
mode: the system detects pollutants in the
outside air and responds by deactivating
the outside air supply when required. The
system then recirculates the air currently
within the vehicle.
Depending upon air quality, in the auto-
matic mode the system may start to alter-
nate between its outside-air and
recirculated-air modes
>Right-hand indicator lamp on Ð Recircu-
lated-air mode: the supply of outside air
into the vehicle is permanently blocked.
The system then recirculates the air
currently within the vehicle.
If condensation starts to form on the
inside window surfaces during opera-
tion in the recirculated-air mode, you
should switch it off while also increasing air
supply as required.<
Residual heat mode
The system uses the warmth
stored in the engine to heat the
interior when the ignition is off,
for instance, while the vehicle is
stopped at a school to pick up a
child.
