Fuel gauge Temperature gauge Service Interval Display Once the indicator lamp stays on
continuously, there are still approx.
2 gallons (8 liters) of fuel in the fuel
tank.
Fuel tank capacity: approx. 16.6 gal.
(63 liters).
If the tilt of the vehicle varies (when you
are driving in mountainous areas, for
example), the needle may fluctuate
slightly.
Please refuel early, since driving
to the last drop of fuel can result in
damage to the engine and/or catalytic
converter.<
When you switch on the ignition, the
indicator lamp lights up briefly as a
functional check.
BlueThe engine is still cold. Drive at
moderate engine and vehicle speeds. RedWhen you switch on the ignition, the
warning lamp comes on briefly to
confirm that the system is operational.
If the lamp comes on while operating
the vehicle, the engine has overheated.
Switch off the engine immediately and
allow it to cool down.
Checking coolant level, refer to
page 112.Between the blue and red zonesNormal operating range. The needle
may rise as far as the edge of the red
sector in normal operation.
Remaining distance for serviceThe displays shown in the illustration
appear for a few seconds when the
ignition key is in position 1 or after the
engine is started.
The next service due appears with the
message OILSERVICE or INSPECTION,
together with the distance remaining
before the next scheduled service.
The computer bases its calculations of
the remaining distance on the
preceding driving style.
A flashing message and a "Ð" in front of
the number mean that the service
interval has already been exceeded by
the distance shown on the display.
Please contact your BMW center for an
appointment.

DisplayThe following information or conditions
are displayed from ignition key posi-
tion 2 on, until the cause has been
corrected:
1 Inspect the low beams and the high
beams, as well as the parking lamps
2 Door open
3 Luggage compartment lid open
4 Check brake and tail lamps.
After completion of a trip and upon
opening the driver's door, an acoustic
signal will sound yet not be displayed,
as a reminder that the low beam head-
lamps have not been turned off.
Mode selectionWith the ignition key in position 1 and
higher, you can use the button in the
turn signal lever to retrieve information
from the computer for display in the
instrument cluster. By pressing the
button briefly in the direction of the
steering column, you can call up a new
function for display.
The displays appear in the following
order:
Time of day, outside temperature,
average fuel consumption, cruising
range, average vehicle speed.
From ignition key position 1, the last
active setting is displayed.
ClockIf you wish to have a permanent time
display, you can make this adjustment
in the car radio display (refer to the
Radio Owner's Manual).

ComputerAdjustments From ignition key position 1 the time of
day appears in the display.
To set ahead: turn the knob to the right.
To set back: turn the knob to the left.
The adjustment speed will increase the
longer you continue to hold the knob.
To change the display mode: press the
knob briefly. Every time you press the
knob, the clock display alternates
between the 12-hour or 24-hour mode.
In ignition key position 0: the time is
displayed for a few seconds after you
press the left knob (refer to "Odom-
eter", page 70).
Outside temperature You can change the units of measure
(6/7) for the outside temperature
display by pressing the right-hand reset
knob in the instrument cluster while the
temperature display is active.
Ice warning If the outside temperature drops to
about 37.5 7 (+3 6), then the
computer will automatically switch to
show the outside temperature. In addi-
tion, a signal sounds as a warning and
the display flashes for a brief period.
The ice warning does not alter the
fact that surface ice can form at
temperatures above 37.5 7 (+3 6), on
bridges or shaded road surfaces, for
instance.<

Computer Average fuel consumption If you continue to hold the button on the
turn signal lever, the average fuel
consumption last displayed is recalcu-
lated from that point.
Range The computer bases its calculations of
the cruising range on the preceding
driving style.Average speed If you continue to hold the button on the
turn signal lever, the average fuel
consumption last displayed for that
speed is recalculated from that point in
time.
Any time spent when the vehicle is
stationary and the engine is shut off is
ignored for the calculation.

OverviewControlsMaintenanceRepairsDataIndex
The conceptPDC provides extra safety and conve-
nience during parking maneuvers by
providing an acoustic signal to indicate
the distance to an object. To do this,
four ultrasonic sensors in the rear
bumper measure the distance to the
nearest object.The monitoring range for
the two rear sensors extends outward
roughly 2 ft (60 cm). The range for the
two center sensors is approx. 4.9 ft
(1.50 m) wide.
The system starts to operate automati-
cally about one second after you select
reverse with the ignition key in
position 2. PDC is deactivated when
you shift back out of reverse.
Acoustic signalsThe distance to the nearest object is
indicated by a tone sounding at various
intervals. As the distance between
vehicle and object decreases, the inter-
vals between the tones become
shorter. A continuous tone indicates the
presence of an object less than 1 ft
(30 cm) away.
The warning signal is canceled after
approx. three seconds if the distance to
the obstacle remains constant during
this time (if you are moving parallel to a
wall, for instance).
System malfunctions will be indicated
by a continuous high-pitched tone
when the system is activated the first
time. Please have your BMW center
resolve the problem.The PDC does not remove the
driver's personal responsibility
for evaluating the distance between the
vehicle and any obstacles. Even when
sensors are involved, there is a blind
spot in which objects cannot be
detected. This applies especially in
those cases where the system
approaches the physical limits of ultra-
sonic measurement, as occurs with tow
bars and trailer couplings, and in the
vicinity of thin or wedge-shaped
objects.
Certain sources of sound, such as a
loud radio, could drown the PDC signal
tone.<
Keep the sensors clean and free
of ice or snow in order to ensure
that they continue to operate effec-
tively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Always maintain a distance of more
than 4 in (10 cm).<

Dynamic Stability Control (DSC)

The conceptDSC 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. In addition, it also recognizes
unstable driving conditions such as
under- or oversteering on curves, and
helps the vehicle remain on a steady
course by using the engine and brake
system to intervene at the different
wheels Ð doing only what it can within
the laws of physics, of course.
The DSC is operational every time you
start the engine. The laws of physics cannot be
repealed, even with DSC. The
results of driving irresponsibly rest with
the driver. We therefore urge you to
avoid using the additional safety margin
of the system as an excuse for taking
risks.
Do not make any modifications to the
DSC system. Allow only authorized
technicians to perform service proce-
dures on the DSC.<
At first, you may need some time to
become accustomed to this system's
intervention. However, it guarantees
optimum drive force and at the same
time, the best possible vehicle stability.
Indicator lamp
The indicator lamp in the instru-
ment cluster will go out shortly
after the ignition has been
switched on, refer to pages 18, 19.
>Indicator lamp flashes: the DSC is
active and is controlling the drive
torque based on driving conditions
>If the indicator lamp fails to go out
after the engine has been started, or
if it comes on during normal driving
and stays on: the DSC has been
deactivated via the button or there is
a malfunction. You can continue to
drive the vehicle normally, but
without DSC. Please consult your
BMW center for repairs.

Dynamic Stability Control (DSC) Flat Tire MonitorTo deactivate DSCPress the DSC button briefly; the indi-
cator lamp will light up and stay on.
The vehicle does not execute the
stability-enhancement and traction-
control functions when DSC is deacti-
vated.
We recommend that you deactivate
DSC for increased traction:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving with snow chains.
To maintain vehicle stability,
always drive with the DSC acti-
vated on whenever possible.<
Reactivating the DSCPress the button again; the indicator
lamp goes out.Dynamic Brake Control (DBC)DBC is an integral component of the
DSC system.
If you apply the brakes rapidly, this
system automatically generates
maximum braking force boost and thus
helps to achieve the shortest possible
braking distance in "panic braking" situ-
ations. All of the benefits of the ABS
system are exploited under these
circumstances.
Do not reduce the pressure on the
brake pedal for the duration of the
brake application. When the brake
pedal is released, the DBC is deacti-
vated.
The conceptAs you drive, the Flat Tire Monitor
keeps track of pressure levels in all four
tires in order to detect and warn of any
substantial pressure loss.
The system actually detects pressure
loss by monitoring differences in the
relative speeds of the four wheels. It
interprets variations outside specified
limits as severe pressure loss, and then
responds by generating a warning.

78n
Flat Tire MonitorInitializing the systemInitializing is necessary to familiarize the
system with the correct tire inflation
pressure.
Repeat this process after any changes
in tire inflation pressure, tire replace-
ment or rotation.
1. Check the tire inflation pressure in all
the tires, comparing them with the
inflation pressure table (page 25),
and adjusting their pressure if neces-
sary
2. Turn the ignition key to position 2
3. Press button as long as you need to
until the indicator lamp in the instru-
ment cluster lights up. After a little
while, the indicator lamp will go out
by itself
4. After a few minutes, the Flat Tire
Monitor will accept the current infla-
tion pressure as the value to be
measured against, and from that
point on, can detect and report a flat
tire.
Activating/deactivating the
systemThe system is automatically activated in
ignition key position 2 and conse-
quently is on whenever the vehicle is
operated.
To deactivate the system, tap the
button, the indicator lamp will light up
yellow.
To activate the system, tap the button
again; the indicator lamp goes out.
Deactivate the system when snow
chains are mounted, since false warn-
ings and undetected losses in pressure
are possible under these kinds of
conditions.

Flat Tire Monitor
M Engine dynamics control
In the event of a flat tire
The indicator lamp in the instru-
ment cluster will light up red in
the event of a flat tire with
ensuing loss in pressure. In addition, an
acoustic signal is sounded. To come to
an immediate stop, reduce speed, while
avoiding any sudden, jerky braking or
steering maneuvers.
Fix the flat tire using the M Mobility
system, refer to page 126.
Reset the indicator lamp: the red indi-
cator lamp has to be switched off
manually after putting on a new wheel.
At this point, hold the Flat Tire Monitor
button down until the indicator lamp
goes out. Reinitialize the system after-
ward.
The Flat Tire Monitor cannot alert
you to severe and sudden tire
damage caused by external factors.
Another factor which the Flat Tire
Monitor does not recognize is the
balanced and very gradual pressure
loss that takes place in all tires over an
extended period of time.<
Check the tire inflation pressure
on a regular basis and correct if
necessary, refer to page 24.
Under certain circumstances, there
may be false warnings or a delayed
detection of losses in pressure when
driving on snow-covered or slippery
road surfaces.
Performance-oriented driving (slip at
the drive wheels, high levels of lateral
acceleration) can also delay the
appearance of status reports in the Flat
Tire Monitor's display.<
System malfunctionAs long as there is still a malfunction,
the indicator lamp in the instrument
cluster will stay lit up yellow.
Please contact your BMW center for
additional information.
The system (sport-mode identification)
will cause the engine to respond spon-
taneously to the motion of the acceler-
ator pedal. Activating/deactivating
sport-mode identificationActivating: with the key in ignition key
position 2, press the sport button. The
indicator lamp will light up.
The vehicle may gain speed
without any additional pressure on
the accelerator pedal when the system
is activated.<
Deactivating: press the sport button
again; the indicator lamp will go out.
The sporty-comfortable mode is deacti-
vated every time the engine is started.

Parking lamps
With the switch in this position,
the front, rear and side vehicle
lighting comes on. You can use
the parking lamps for parking. Refer to
page 81 for one-sided lighting as an
additional possibility for parking.
Low beams
When you switch the ignition off
with the low-beam headlamps
on, only the parking lamps will
remain on.
"Follow me home":
When you activate the headlamp
flasher after parking the vehicle and
switching off the lamps, the low beams
will come on for a brief period. You can
also have this function deactivated.<
LIGHTS ON warningWhenever you open the driver's door,
after having turned the ignition key to
position 0, you will hear an acoustic
signal for a few seconds to remind you
that the lamps have not been switched
off.Daytime driving lamps
*
The headlamps are automatically
switched on for daytime driving at
ignition key position 2.
Automatic headlamp control
*
When the switch is in this posi-
tion the system automatically
responds to changes in ambient
light ( in tunnels, at dusk, etc.) as well as
rain and snow by switching the low
beams on or off.<
The headlamps and other external
lamps remain on when you switch
on the fog lamps manually while the
headlamps are on following automatic
activation.<
Automatic headlamp control
cannot serve as a substitute for
your personal judgement in determining
when the lamps should be switched on.
The sensors are not able to detect fog,
for example . When these kinds of low-
visibility situations arise you should
switch on the lamps manually to ensure
continued safety.<

You can have the sensitivity of
your vehicle's automatic head-
lamp control adjusted.<
