TachometerVariable pre-warning zoneThe yellow pre-warning zone displays
current permissible engine speeds,
depending on the engine temperature.
As the engine temperature climbs,
some of the sectors for this pre-warning
zones will go out one after the other.
Avoid engine speeds in the early warn-
ing zone if possible.
Never allow the engine to operate with
the needle in the red overspeed zone of
the gauge.
To protect the engine, the fuel supply is
interrupted when you approach this
sector.
Temperature gaugeThe general operating temperature lies
between 1757/806 and 2507/
1206. During high-performance driv-
ing, do not exceed a maximum value of
3007/1506.

Fuel gaugeOnce the indicator lamp stays on con-
tinuously, 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.
Fill the fuel tank before it is com-
pletely empty. Driving to the last
drop of fuel can prevent the engine
from operating properly and result in
damage.<
When you switch on the ignition, the
indicator lamp lights up briefly as an
operation check.
Engine coolant temperature gaugeBlueThe engine is still cold. Drive at moder-
ate engine and vehicle speeds.RedWhen you switch on the ignition, the
warning lamp comes on briefly as an
operation check.
If the lamp comes on while operating
the vehicle: the engine has overheated.
Switch off the engine immediately and
allow it to cool down.
To check the coolant level, refer to
page 120.
Between the blue and red zonesNormal operating range. The needle
may rise as far as the edge of the red
sector during normal operation.

Service interval displayRemaining distance to next
serviceThe displays shown in the illustration
appear for a few seconds when the
ignition key is in position 1 or higher or
after the engine is started.
The next service due appears with the
message OIL SERVICE or
INSPECTION, together with the dis-
tance remaining in miles – in kilometers
in Canada – before the next scheduled
service.
The computer bases its calculations of
the remaining distance on the preced-
ing driving style.
A flashing message and a "–" in front of
the number mean that the service inter-
val has already been exceeded by the
distance shown on the display. Please
contact your BMW center for an
appointment.
Check ControlDisplayThe following information or conditions
are displayed when the ignition key is in
position 2 or higher, until the cause has
been corrected:
1Inspect the low-beam and high-beam
headlamps, as well as the parking
lamps
2Door open
3Luggage compartment lid open
4Check tail or brake lamps
When you open the driver's door after
completing a journey, an acoustic
warning signal will sound if you have
forgotten to turn off the headlamps.

ComputerMode 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. Each time you press
the button briefly in the direction of the
steering column, a new function is
called up in the display.
The displays appear in the following
order:
Time of day, outside temperature, aver-
age fuel consumption, cruising range,
average vehicle speed.
When the ignition key is in position 1 or
higher, the last active setting is dis-
played.
Outside temperatureYou can change the units of measure
6/7 for the outside temperature dis-
play by pressing the right-hand reset
button in the instrument cluster while
the temperature display is active. The
units of measure 6/7 in the tempera-
ture display of the automatic climate
control change automatically, refer to
page 90.Ice warningIf the outside temperature drops to
about 37.57/+36, then the computer
will automatically switch to a display of
the outside temperature. In addition, a
signal sounds as a warning and the dis-
play flashes for a brief period.
After giving an ice warning, the
display returns to the previous
setting.<
The ice warning does not alter the
fact that surface ice can form at
temperatures above 37.57/+36, on
bridges or shaded road surfaces, for
instance.<

80Technology for safety and driving convenience
Park Distance Control (PDC)*The conceptPDC assists you when you back into a
parking space. Acoustic signals alert
you to the momentary distance to an
object behind your vehicle. To do this,
four ultrasonic sensors in the rear
bumper measure the distance to the
nearest object. The range for the sen-
sors located at both rear corners ends
approx. 2 ft/60 cm behind the bumpers.
The range for the two middle sensors is
slightly less than 5 ft/1.50 m.
PDC is a parking aid that can
identify objects if they are
approached slowly, as is generally the
case when parking. Avoid driving
towards objects rapidly; due to underly-
ing physical principles, the system may
otherwise alert you too late for you to
take evasive steps.<
The system is activated automatically
about one second after you engage
Reverse with the ignition key in
position 2.
Let this short period elapse before
driving backwards.<
PDC is deactivated when you shift back
out of Reverse.
You can have a signal set to con-
firm that the PDC has been acti-
vated.<
Acoustic signalsThe distance to the nearest object is
indicated by a tone sounding at various
intervals. As the distance between vehi-
cle and object decreases, the intervals
between the tones become shorter. A
continuous tone indicates the pres-
ence of an object less than 1 ft/30 cm
away.
The warning signal is canceled after
approx. three seconds if the distance to
the object 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.
PDC does not replace the driver's
personal responsibility for evaluat-
ing the distance between the vehicle
and any objects. 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 ultrasonic measurement, as
occurs with tow bars and trailer cou-
plings, and in the vicinity of thin or
wedge-shaped objects. Moreover, low
objects that have already been
detected – such as a curb edge – can
disappear out of the detection range of
the sensors before a continuous tone
sounds.
Loud sources of sound from outside or
inside the vehicle could drown out the
PDC signal tone.<
Keep the sensors clean and free
of ice or snow in order to ensure
that they will 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 recognizes
unstable vehicle conditions, such as
understeering or oversteering, and,
within physically feasible limits, helps
keeping the vehicle on a steady course
by reducing the engine speed and
brake applications to the individual
wheels.
DSC starts up automatically each 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 accus-
tomed to this system's intervention.
However, it guarantees optimum drive
force and at the same time, the best
possible vehicle stability. The indicator lamp in the instru-
ment cluster will go out shortly
after the ignition has been
switched on, refer to page 20.
>Indicator lamp flashes: 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: DSC has been deacti-
vated via the button or is defective.
You can continue to drive the vehicle
normally, but without DSC. Please
consult your BMW center for repairs.
To deactivate DSCPress the button briefly; the indicator
lamp comes on and stays on.
The vehicle does not execute the stabil-
ity-enhancement and traction-control
functions when DSC is deactivated.
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
>When driving on snow-covered
grades, in deep snow, or on a snow-
covered surface that has been
packed down from being driven on.
To maintain vehicle stability,
always drive with the DSC acti-
vated on whenever possible.<

Initializing the systemInitializing is necessary to familiarize the
system with the correct inflation pres-
sures.
Repeat this process after any changes
in tire inflation pressure, tire rotation or
replacement.
1. Check the tire inflation pressures in
all the tires, comparing them with the
inflation pressure table on page 25,
and adjust them if necessary
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 pressures as the values to be
measured against, and from that
point on can detect and report a flat
tire.
To activate/deactivate 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 but-
ton, the indicator lamp will light up yel-
low.
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 con-
ditions.

86Lamps
Parking lamps/Low beamsParking lamps
The front, rear and side vehicle
lighting is switched on. You can
use this to signal the position of
the vehicle when it is parked. For light-
ing on one side for parking as an addi-
tional feature, refer to page 87.
Low beams
When you switch the ignition off
with the low-beam headlamps
on, only the parking lamps will
remain on.
Follow me home lampsWhen you activate the headlamp
flasher after parking the vehicle and
switching off the lights, 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*If you desire, the light switch can be left
in the low-beam position: when the
ignition is switched off, the external
lighting is also switched off.
When required, switch on the parking
lamps as usual as described under
Parking lamps.
You can have the activation set-
tings for the daytime driving lamps
programmed on your vehicle. When the switch is in this posi-
tion the system automatically
responds to changes in ambient
light – in tunnels, at dusk, etc. – and in
the event of rain and snow – by switch-
ing the low beams on or off.
The vehicle's external lamps
remain on constantly when you
switch on the front fog lamps after the
headlamps have come on automati-
cally.<
Automatic headlamp control can-
not serve as a substitute for your
personal judgement in determining
when the lamps should be switched on.
For example, the sensors are not able
to detect fog. In such situations switch
on the lamp manually, as otherwise a
safety hazard will result.<
You can have the sensitivity of
your vehicle's automatic head-
lamp control adjusted.<
