Park Distance Control (PDC)
*
The PDC assists you when you are
parking. Acoustic signals warn you
of the distance to an obstacle. In addi-
tion, four ultrasonic sensors in each the
front and rear bumpers measure the
distance from the nearest object. The
monitoring range for the four front sen-
sors and that of the two rear corner
sensors ends approx. 2 feet (60 cm)
beyond the respective bumper. The two
center sensors cover a distance of
approx. 5 feet (1.50 m).380de619
The system starts to operate automati-
cally about one second after you move
the selector lever to "R" when the igni-
tion key is in position 2. It is similarly
deactivated when you move the selec-
tor lever position from the "R" position.
The indicator lamp in the button (arrow)
comes on to signal the active status.
Manual activation/deactivation is possi-
ble using the button in the center
console (arrow) (indicator lamp comes
on/goes out). The system deactivates
once the vehicle travels approximately
160 ft (50 m) or exceeds a speed of
about 18 mph (30 km/h). It must then be
switched on again as desired.
Acoustical signalsThe distance to an obstruction in the
front is indicated by a higher interval
tone, while the distance to an obstruc-
tion in the rear is indicated by a deeper
tone. As the distance between vehicle
and object decreases, the intervals be-
tween 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 ap-
prox. three seconds if the distance to
the obstruction remains constant during
this time (if you are moving parallel to a
wall, for instance).
System malfunctions are indicated by a
short, continuous tone and a flashing
indicator lamp (indicator lamp only
when the system is activated by shifting
the transmission into "R").
Switch the system off and consult an
authorized BMW center to have the
problem corrected.

Jump-startingNever use spray starter fluids to start
the engine.
If the battery is discharged, you can use
two jumper cables to start your car with
power from the battery of a second ve-
hicle. Always use jumper cables with
fully insulated handles on the terminal
clamps.
Do not touch high-voltage wiring
and cables on a running engine.
There is a risk of fatal injury if you do
this.<
Carefully comply with the following in-
structions to avoid personal injury and
damage to one or both vehicles:
1 Ensure that the battery on the sup-
port vehicle is also rated at 12 volts,
and that the capacities of the two
batteries (Ah) are roughly comparable
(printed on casing)
2 Leave your battery connected to the
car electrical system
3 Make sure that there is no contact
between the bodywork of the two ve-
hicles – short circuit risk.
4 Start by connecting the jumper cable
from the positive terminal of the sup-
port vehicle to the positive terminal
connector located in your BMW's en-
gine compartment. The cover of the
auxiliary terminal for jump starting is
marked with "Batt. +" (refer to the il-
lustration). Remove by pulling tab.
The illustration shows the auxiliary
terminal for jump starting the BMW
740i/L as an example. For the BMW
750iL: Refer to "Engine compart-
ment" on page 140380de089
5 Then connect the negative terminals.
Attach the cable to either the support
vehicle's negative battery terminal,
or to a suitable ground on its engine
or bodywork. Then connect the other
end of the cable to ground on the ve-
hicle's engine or bodywork which is
to be started. Then connect the other
end of the cable to a ground on your
vehicle's engine or bodywork (for in-
stance, the nuts on the strut dome.
Refer to the arrows in the illustration
above)
Follow the same sequence for
connecting the jumper cables if
you assist in jump-starting another ve-
hicle. If you do not, there is a risk of in-
jury caused by spark generation at the
battery.< 380de117
