PDC Park Distance Control*
The concept
The PDC assists you with maneuvering in tight
parking spaces. Acoustic signals and a visual
indicator
warn you of the presence of an object
behind your vehicle. To measure the distance,
there are four ultrasonic sensors in either
bumper.
These sensors have a range of approx. 6.5 ft/
2 m. However, an acoustic warning does not
sound until an object is approx. 24 in/60 cm
from the corner sensors, or approx. 5 ft/1.50 m
from the center sensors.
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, oth-
erwise physical circumstances may lead to the
system warning being issued too late.<
Switching on automatically
With the engine running or the ignition switched
on, the system is activated after approx. 1 sec-
ond when you engage reverse gear or move the
automatic transmission selector lever to
position R. Wait this short period before driving.
Switching off automatically
After approx. 165 ft/50 m of driving or above
approx. 20 mph/approx. 30 km/h, the system
switches off and the LED goes out.
Signal tones
When nearing an object, its position is indicated
correspondingly by an interval tone. As the dis-
tance between vehicle and object decreases,
the intervals between the tones become
shorter. If the distance to the nearest object
falls to below roughly 1 ft/30 cm, then a contin-
uous tone sounds.
An interval tone is interrupted after approx.
3seconds>if you remain in front of an object that has
been detected by only one of the corner
sensors
>if you are driving parallel to a wall.
Malfunction
The indicator lamp in the instrument
cluster comes on. PDC is malfunc-
tioning. A message appears on the
Control Display. Have the system checked.
To avoid this problem, keep the sensors clean
and free of ice or snow in order to ensure that
they will continue to operate effectively. When
using a high-pressure cleaner, do not spray the
sensors for extended periods of time and only
from a distance of at least 4 in/10 cm.
PDC with visual warning
You can also have the system show distances
to objects on the Control Display. The contours
of distant objects are shown on the Control Dis-
play even before the acoustic signal sounds.
The setting is stored for the remote control cur-
rently in use.
iDrive, for operating principle refer to page16.

Technology for driving comfort and safety
96 equipped with a tire pressure monitoring sys-
tem, TPMS, that illuminates a low tire pressure
telltale when one or more of your tires are signif-
icantly under-inflated. Accordingly, when the
low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving
on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle’s han-
dling and stopping ability. Please note that the
TPMS is not a substitute for proper tire mainte-
nance, and it is the driver’s responsibility to
maintain correct tire pressure, even if underin-
flation has not reached the level at which the
TPMS low tire pressure telltale illuminates.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the sys-
tem detects a malfunction, the telltale will flash
for approximately one minute and then remain
continuously lit. This sequence will continue
upon subsequent vehicle startups as long as
the malfunction exists. When the malfunction
indicator is illuminated, the system may not be
able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of
replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
Active steering*
The concept
Active steering varies the turning angle of the
front wheels in relation to steering wheel move-
ments. It also varies the steering force required
to turn the wheels depending on the speed at
which you are driving.
When you are driving in the low road-speed
range, e.g. in a town or when parking, the steer-
ing angle increases, i.e. the steering becomes very direct, and less effort is required to turn the
wheels. In the higher speed range, on the other
hand, the steering angle is reduced more and
more. This improves the handling capability of
your BMW over the entire speed range.
In critical situations, the system can make tar-
geted corrections to the steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes. This stabilizing
intervention is simultaneously deactivated
when DSC is switched off, refer to page90.
Malfunction
The warning lamps come on. Active
steering is no longer operational. At
low speeds, greater steering wheel
movements are required, whereas at
higher speeds the vehicle reacts more sensi-
tively to steering wheel movements. The stabil-
ity-enhancing feature may also be deactivated.
Drive cautiously and think well ahead. Have the
system checked.

Lamps
102 of the road surface. Depending on the steering
angle and other parameters, the light from the
headlamp follows the course of the road.
In tight curves at speeds up to 40 mph/70 km/h,
e.g. on mountainous roads or when turning, an
additional, corner-illuminating lamp is switched
on that lights up the inside area of the curve.
Activating Adaptive Head Light
With the ignition switched on, turn the light
switch to position 3, refer to page100.
The corner-illuminating lamp is switched on
automatically, depending on the steering wheel
angle or turn signal indicator.
To avoid blinding oncoming traffic, the Adaptive
Head Light directs light towards the front pas-
senger side when the vehicle is at a standstill.
When you are reversing, only the corner-illumi-
nating lamps are active and switched on on
both sides.
Malfunction
The LED next to the symbol for automatic head-
lamp control flashes. Adaptive Head Light is
malfunctioning or has failed. Have the system
checked as soon as possible.

There is an additional option of switching on the
lamps on the side of the car facing the road
when parked.
Switching on
After parking the vehicle, press the lever up or
down beyond the pressure point for a longer
period, arrow 3.
The roadside parking lamps drain the bat-
tery. Therefore, do not leave them on for
unduly long periods of time, otherwise the bat-
tery might not have enough power to start the
engine.<
Switching off
Press the lever in the opposite direction to the
pressure point, arrow 3.
Fog lamps
The parking lamps or low beams must
be switched on for the fog lamps to
operate. The green indicator lamp in
the instrument cluster lights up whenever the
fog lamps are on.
The fog lamps are switched off while you acti-
vate the headlamp flasher or switch on the high
beams.
If the automatic headlamp control is acti-
vated, the low beams will come on auto-
matically when you switch on the fog lamps.<

What to do if …
>a navigation DVD is inserted, but an instruc-
tion to insert the DVD appears on the Con-
trol Display?
The navigation DVD may not be the correct
DVD for the navigation system. This infor-
mation is indicated on the DVD label.
>you request the current position of your
vehicle, but do not receive a precise dis-
play?
The system is unable to receive enough
GPS signals at your current position due to
obstructions, your current position is not
yet available on your navigation DVD, or the
system is in the process of calculating your
current position. As a rule, reception is
guaranteed when you are in the open.
>the destination guidance does not accept a
destination?
The data of the destination is not stored on
the navigation DVD that is loaded. Choose a
destination as close as possible to the orig-
inal one.
>the destination guidance does not accept
an address without the street name?
On the navigation DVD, no downtown area
can be determined for the city or town
entered. Enter any street, or a destination
such as the railway station in the selected
town, and then start the destination guid-
ance.
>you want to enter a destination for the des-
tination guidance, but it is not possible to
select the letters for your desired entry?
The data of the destination is not stored on
the navigation DVD that is loaded. In this
case, the system will not offer you any let-
ters to choose from. Choose a destination
as close as possible to the original one.
>the system stops furnishing directions on
which way to turn as you approach intersec-
tions?
You are driving in an area that has not yet
been completely recorded on the naviga-tion DVD. Instead of an arrow indicating a
turn, you will see an arrow which indicates
the general direction of your planned route.
Or you have left the recommended route
and the system requires a few seconds to
calculate a new recommended route.
>the navigation system does not react to
entries?
If the battery was disconnected, it takes
about 10 minutes before the system is once
again operational.

Changing wheels
Your BMW is equipped with Run-Flat Tires as
standard. This removes the need to change a
wheel immediately in the event of a puncture.
For information on continuing to drive with a
damaged tire, refer to Indication of a flat tire on
page93.
The symbol identifying Run-Flat Tires is a circle
with the letters RSC on the sidewall, refer to
Run-Flat Tires, page222.
When mounting new tires or changing over
from summer to winter tires and vice versa,
mount Run-Flat Tires for your own safety. In the
event of a flat, no spare wheel is available. Your
BMW center will be glad to advise you. Refer
also to New wheels and tires, page222.
The tools for changing wheels are avail-
able as optional accessories from your
BMW center.<
