2004 BMW 645CI COUPE amp

Driving
58 speed; thus, for example, a downshift
that would cause the engine to overrev
will not be executed by the system
>When the vehicle is stationary, the
transmission automatically downshifts
into first gear
>Shortly before dropping below a gear-
dependent minimum speed, the trans-
mission downshifts automatically even
without your intervention.
Malfunction
The warning lamp lights up and a
message appears on the Control
Display. There is a malfunction in
the transmission system. Avoid high loads.
While it will remain still possible to move
the selector lever to any desired position,
the transmission will revert to operation in
its default mode with only a limited number
of forward gears.
Have the system checked as soon as pos-
sible.
Information on jump-starting and towing
begins on page 185.
Overheating
The warning lamp lights up and a
message appears on the Control
Display. In addition, an acoustic
signal sounds. Overheating in the area of
the transmission. If possible, stop or drive
off quickly so that the system can cool
down.
Automatic transmission
with Steptronic*
In addition to the fully automatic mode, you
can also shift manually with Steptronic,
refer to page 59.
Selector-lever positions
P R N D M/S + –
Possible displays
P R N D DS M1 to M6
The selector lever position is indicated, and
in the manual mode the gear currently
engaged.
Changing selector-lever positions
An interlock prevents inadvertent gear-
shifts into selector-lever positions R and P.
To cancel the interlock, press the button on
the front of the selector lever knob, refer to
arrow.
Shiftlock
Press the brake pedal before shifting out
of P or N; the shift command will not be
executed unless the brake is applied.
To prevent the vehicle from creeping after
you select a driving position, maintain pres-
sure on the brake pedal until you are ready
to start.
To prevent the vehicle from rolling,
always select selector-lever posi-
tion P and engage the handbrake before
leaving the vehicle with the engine running.
Never leave an unattended vehicle with the
engine running, as such a vehicle repre-
sents a potential safety hazard.<

P Parking
Select only when the vehicle is completely
stationary. The rear wheels are blocked.
R Reverse
Select only when the vehicle is completely
stationary.
N Neutral
E.g. engage in car washes. The vehicle can
roll.
D Drive, automatic position
Position for normal vehicle operation.
All forward gears are available.
Under normal operating conditions, fuel
consumption is lowest when driving in
position D.
Kickdown
The kickdown mode provides maximum
acceleration:
Press the accelerator pedal beyond the
full-throttle resistance point.
M/S manual operation and
Sport program
Move the selector lever from position D to

This position is recommended for a perfor-
mance-oriented driving style. It is engaged
automatically when the Dynamic Driving
Control is activated, see below.
When the selector lever is moved slightly
towards + or –, the Steptronic shifts gear
and manual operation is activated. The
instrument cluster shows M1 through M6.Upshifts and downshifts are executed only
when they will result in a plausible combi-
nation of engine and vehicle speed; thus,
for example, a downshift that would cause
the engine to overrev will not be executed
by the system. The selected gear appears
briefly in the instrument cluster, followed by
the current gear.
To use the automatic function again, move
the selector lever to the right into posi-
tion D.
Malfunction
The warning lamp lights up and a
message appears on the Control
Display. There is a malfunction in

PDC Park Distance Control*
The concept
The PDC assists you when you are parking.
Signal tones and a visual display
* indicate
the current distance to an object behind or
in front of your vehicle. To measure the dis-
tance, there are four ultrasonic sensors in
each bumper. The sensors at the front and
at the two rear corners have a range of
approx. 20 in/50 cm; the rear middle sen-
sors have approx. 5 ft/1.50 m.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching an object at high speed,
as otherwise the physical circumstances
would mean that the system warning was
too late.<
Automatic mode
In ignition key position 2, the system auto-
matically assumes operational status after
a few seconds each time you engage
reverse gear or selector-lever position R.
Wait this short period before driving.<
The system is automatically deacti-
vated once the vehicle travels approx.
165 ft/50 m or exceeds a speed of roughly
20 mph/30 km/h; the indicator lamp goes
out. You can reactivate the system manu-
ally as needed.
Manual mode
With the ignition key in position 2, press the
button; the indicator lamp lights up.
Deactivating manual mode
Press the button again; the indicator lamp
goes out.
Signal tones
The signal indicating the distance to the
nearest obstacle is directional. Thus, an
object detected to the left rear of the vehi-
cle will be indicated by a signal tone from
the left rear speaker, etc. As the distance
between vehicle and object decreases, the
intervals between the tones become
shorter. The signal tone becomes continu-
ous once the distance to the nearest object
falls to below roughly 1 ft/30 cm.
The warning signal is canceled after
approx. 3 seconds if you are moving paral-
lel to a wall.
Malfunctions
The indicator lamp within the button
flashes and a message appears on the
Control Display. PDC has failed. Switch off
PDC. Have the system checked.
As a preventive measure, keep the sensors
clean and free of ice or snow in order to
ensure that they will continue to operate
effectively.
PDC with visual warning*
You also enjoy the option of having the sys-
tem show distances to objects on the Con-
trol Display. The Control Display will also
