Variable pre-warning zoneThe orange pre-warning zone displays
current permissible engine speeds,
depending on the engine temperature.
As the engine temperature climbs,
some of the sectors of this pre-warning
zone will go out one after the other.
Avoid engine speeds in the early
warning zone if possible.Warning zone
Be sure to avoid engine sppeds in
the red warning zone, as other-
wise, the engine can be damaged.<
In this range the fuel supply will be
interrupted to protect the engine; the
resulting effect resembles that associ-
ated with a sudden loss of power.
The general operating temperature is
between 175 7 (80 6) and 250 7
(120 6). During performance-oriented
driving, do not exceed the maximum
temperature of 300 7 (150 6).

Service Interval Display 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 previous
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 until the cause has been
corrected:
1 Inspect the low beam and high beam
headlamps, as well as the side 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, if
the low beam headlamps 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.
Starting with 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 radio display (refer to the Radio
Owner's Manual).
You can set the time of day, including
for the car radio display, as follows.

ComputerAdjustments From ignition key position 1:
To set ahead: turn the button to the
right.
To set back: turn the button to the left.
The adjustment speed will increase the
longer you continue to hold the button.
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 button (refer to "Odom-
eter", page 69).
Outside temperature You can change the units of measure
(6/7) for the outside temperature
display by pressing the right-hand reset
button 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.
This warning will repeat itself whenever
the temperature has reached at least
43 7 (+6 6) since the last warning,
and has then dropped further to
37.5 7 (+3 6).
Ice warnings do not exclude the
possibility that surface ice can still
occur at temperatures above 37.5 7
(+3 6), e. g. on bridges and shady
roads.<

The conceptThe PDC assists you when you back
into a parking space. A signal warns
you of the distance to an obstacle. To
do this, four ultrasonic sensors in the
rear bumper measure the distance to
the nearest object. The range for the
sensors 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 4.9 ft
(1.50 meters).
The system is activated automatically
about one second after you engage
reverse with the ignition key in posi-
tion 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 and painted 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). <

Tire Pressure Warning (RDW)The conceptThe Tire Pressure Warning (RDW) moni-
tors the tire pressure in all four wheels
while driving. The system detects
whenever the inflation pressure in a tire
drops significantly.
Controlling the tire pressure is based
on monitoring the speed of the tires
relative to each other. A flat tire is
detected and reported because the
speed suddenly deviate drastically from
one another.
Initializing the systemInitializing is necessary to familiarize the
system with the correct inflation pres-
sure.
Repeat this process after any changes
in tire inflation pressure, tire rotation or
replacement. Do not carry out further
system initialization after correcting the
inflation pressure and letting the system
"learn" what condition is required.
1 Check the tire inflation pressure in all
the tires, comparing them with the
inflation pressure table (page 27),
and adjusting their pressure if neces-
sary
2 Turn the ignition key to position 2
3 Continue to press the button until the
yellow indicator lamp in the instru-
ment cluster lights up. After a short
time, the indicator lamp will go out
automatically
4 After a few minutes, the RDW will
accept the current inflation pressure
as the value to be measured against,
and from that point on, can detect
and report a flat tire.

Tire Pressure Warning (RDW)Activating/deactivating the
systemThe system is automatically active in
ignition key position 2 and is therefore
always on during driving.
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 while driving
with snow chains, since false warnings
and undetected losses in pressure are
possible under these kinds of condi-
tions.
Flat tire
The indicator lamp in the instru-
ment cluster will light up red in
the event of tire pressure loss.
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 145).
Reset the indicator lamp: the red indi-
cator lamp must be switched off manu-
ally after mounting a new wheel. At this
point, hold the RDW switch down until
the indicator lamp goes out. Reinitialize
the system afterward.
The RDW cannot alert you to
severe and sudden tire damage
caused by external factors.
The RDW will not identify the natural
loss of pressure in all four tires, either.<
Check the tire inflation pressure
on a regular basis and correct if
necessary. Refer to page 26.
Under certain circumstances, there
may be false warnings or a delayed
detection of pressure losses when
driving on snow-covered or slippery
road surfaces.
A sporty driving style (slip at the wheels
receiving the torque, high lateral accel-
eration) can lead to delayed RDW warn-
ings.<
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.
