If the indicator lamp comes on,
there is a malfunction in the
transmission system.
Bring the vehicle to a stop. Move the
transmission selector lever to P. Set the
parking brake and turn the engine off –
ignition key to position 0.
Wait a few seconds, then start the
engine.
If the indicator lamp goes out after a
few seconds, normal transmission per-
formance has been restored. You may
continue to drive as usual.
If the indicator lamp does not go out,
you can place the selector lever in all
positions. However, the vehicle will now
only operate in 3rd and 4th gear.
If this happens, avoid extreme engine
loads and consult the nearest autho-
rized BMW center.
Never work in the engine com-
partment when a drive gear –
forward or reverse – is engaged. If you
do this, the vehicle could move.<
For towing or jump-starting, refer to the

Cruise control*You can store and automatically main-
tain any desired vehicle speed above
approx. 20 mph / 30 km/h.
The cruise control is available whenever
the engine is running and the system
has been activated.To activate the systemWith the ignition key in position 2:
Press the button. The indicator lamp in
the instrument cluster comes on, refer
to page 20. You can now use the cruise
control.
Do not use cruise control on twist-
ing roads, when high traffic den-
sity prevents driving at a constant
speed, or when the road surface is slick
– snow, rain, ice – or loose – rocks or
gravel, sand. until the indicator lamp in the instru-
ment cluster goes out.
Cruise control is also deactivated when
the ignition key is in position 0.
The speed stored in memory is deleted.To store and maintain speed or to
acceleratePress button + briefly:
The system maintains and stores the
current vehicle speed. Every time you
tap the button, the speed increases by
approx. 0.6 mph / 1 km/h.
Press and hold button +:
The vehicle accelerates without pres-
sure on the accelerator pedal. When
you release the button, the system
maintains and stores the current speed.
If on a downhill gradient the
engine braking effect is not suffi-
cient, the controlled speed can be
exceeded. Speed can drop on uphill
grades if the engine output is insuffi-
cient.<
To deceleratePress button – briefly:
If you are already driving with active
cruise control, the speed is decreased
by approx. 0.6 mph / 1 km/h every time
you tap the button.
Press and hold button –:
With the cruise control active, the sys-
tem automatically reduces the throttle
opening to slow the vehicle. When you
release the button, the system main-
tains and stores the current speed.To interrupt the cruise controlWhen the system is activated, press the
button. The indicator lamp stays on.
You can use the cruise control again
whenever you want by calling up the
speed that was stored last.
In addition, cruise control is interrupted
automatically:
>When the brakes are applied
>When you apply pressure to the
clutch pedal, or when you move the
automatic transmission selector lever
from D to N

Energy controlIndicates the current fuel consumption
in mpg – in liters/100 km on Canadian
models. You can check your current
driving style to see whether it is condu-
cive to economy and minimum exhaust
emissions.
When the vehicle is stationary, the dis-
play goes to Maximum – zero on Cana-
dian models.

Service interval displayRemaining distance to 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 ControlThe following information and/or condi-
tions are indicated using symbols, with
the ignition key in position 2 or higher,
until the condition has been corrected.

Computer*Mode selectionWith the ignition key in position 1 or
higher, you can call up information from
the computer using the button in the
turn signal lever. By pressing the button
briefly toward the steering column, you
can call up a new function for display.
The displays appear in the following
order:
Time of day, outside temperature, aver-
age fuel consumption, cruising range,
average vehicle speed.
With the ignition key 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 96.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.<

77 Technology for safety and driving convenience
Park Distance Control (PDC)*The conceptPDC provides extra safety and conve-
nience during parking maneuvers.
Acoustic signals alert you to the
momentary distance to an object
behind your vehicle. The system fea-
tures four ultrasonic sensors mounted
in your rear bumper. The monitoring
range for the two corner sensors
extends outward roughly 2 ft/60 cm,
while two centrally located sensors
detect objects at distances of up to
approx. 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 starts to operate automati-
cally approx. one second after you
select Reverse or move the selector
lever into the R position with the igni-
tion 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. 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 refer the problem to your
BMW center.
PDC does not remove 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.<
