2011 BMW 3 SERIES sensor

Special windshield
The windshield is part of the system.
The shape of the windshield makes it possible
to display a precise image.
A film in the windshield prevents double images
from being displayed.
Therefore, have the special windshield replaced
by a service center only.
Parking assistant
The concept
This system assists the driver in parking parallel
to the road.
Ultrasound sensors measure parking spaces on
both sides of the vehicle.
The parking assistant calculates the best pos‐
sible parking line and takes control of steering
during the parking procedure.
When parking, also take note of the visual and
acoustic information issued by the PDC and the
parking assistant and accelerate or brake ac‐
cordingly.
A component of the parking assistant is the PDC
Park Distance Control, refer to page 121.
Personal responsibility
The parking assistant does not relieve the
driver of responsibility for the vehicle during the
parking procedure.
Watch the parking space and parking procedure
closely and intervene if necessary; otherwise,
there is the danger of an accident.◀

mines the maintenance requirements.
The system makes it possible to adapt the
amount of maintenance you need to your user
profile.
Detailed information on service requirements,
refer to page 77, can be displayed on the Control
Display.
Service data in the remote control
Information on the required maintenance is con‐
tinuously stored in the remote control. Your
service center will read out this data and suggest
the right array of service procedures for your ve‐
hicle.
Therefore, hand your service specialist the re‐
mote control that you used most recently.
Storage periods
Storage periods during which the vehicle bat‐
tery was disconnected are not taken into ac‐
count.
If this occurs, have a service center update the
time-dependent maintenance procedures,
such as checking brake fluid and, if necessary,
changing the engine oil and the microfilter/acti‐
vated-charcoal filter.
Service history
Perform maintenance work at the service center
and have them recorded in the vehicle data. The
entries are like a service booklet of the docu‐
mentation of regular maintenance.
