Service and warranty
We recommend that you read this publication
thoroughly. Your vehicle is covered by the fol‐
lowing warranties:▷New Vehicle Limited Warranty.▷Rust Perforation Limited Warranty.▷Federal Emissions System Defect War‐
ranty.▷Federal Emissions Performance Warranty.▷California Emission Control System Lim‐
ited Warranty.
Detailed information about these warranties is
listed in the Service and Warranty Information
Booklet for US models or in the Warranty and
Service Guide Booklet for Canadian models.
Your vehicle has been specifically adapted and
designed to meet the particular operating con‐
ditions and homologation requirements in your
country and continental region in order to de‐
liver the full driving pleasure while the vehicle
is operated under those conditions. If you wish
to operate your vehicle in another country or
region, you may be required to adapt your ve‐
hicle to meet different prevailing operating
conditions and homologation requirements.
You should also be aware of any applicable
warranty limitations or exclusions for such
country or region. In such case, please contact
Customer Relations for further information.
Maintenance
Maintain the vehicle regularly to sustain the
road safety, operational reliability and the New
Vehicle Limited Warranty.
Specifications for required maintenance meas‐
ures:▷BMW Maintenance system▷Service and Warranty Information Booklet
for US models▷Warranty and Service Guide Booklet for
Canadian models
If the vehicle is not maintained according to
these specifications, this could result in seri‐
ous damage to the vehicle. Such damage is
not covered by the BMW New Vehicle Limited
Warranty.
Data memory
Many electronic components on your vehicle
are equipped with data memories that tempo‐
rarily or permanently store technical informa‐
tion about the condition of the vehicle, events
and faults. This technical information generally
records the state of a component, a module, a system or the environment:
▷Operating mode of system components, fill
levels for instance.▷Status messages for the vehicle and from
its individual components, e.g., wheel rota‐
tion speed/vehicle speed, deceleration,
transverse acceleration.▷Malfunctions and faults in important sys‐
tem components, e.g., lights and brakes.▷Responses by the vehicle to special situa‐
tions such as airbag deployment or engag‐
ing the stability control system.▷Ambient conditions, such as temperature.
This data is purely technical in nature and is
used to detect and correct faults and to opti‐
mize vehicle functions. Motion profiles over
routes traveled cannot be created from this
data. When service offerings are used, e.g., re‐
pair services, service processes, warranty
claims, quality assurance, this technical infor‐
mation can be read out from the event and
fault memories by the service personnel, in‐

cluding the manufacturer, using special diag‐
nostic tools. You can obtain further information
there if you need it. After an error is corrected,
the information in the fault memory is deleted
or overwritten on a continuous basis.
With the vehicle in use there are situations
where you can associate these technical data
with individuals if combined with other infor‐
mation, e.g., an accident report, damage to the
vehicle, eye witness accounts — possibly with
the assistance of an expert.
Additional functions that are contractually
agreed with the customer - such as vehicle
emergency locating - you can transmit certain
vehicle data from the vehicle.
Event Data Recorder EDR
This vehicle is equipped with an event data re‐
corder EDR. The main purpose of an EDR is to
record, in certain crash or near crash-like situa‐
tions, such as an air bag deployment or hitting
a road obstacle, data that will assist in under‐
standing how a vehicle’s systems performed.
The EDR is designed to record data related to
vehicle dynamics and safety systems for a
short period of time, typically 30 seconds or
less.
The EDR in this vehicle is designed to record
such data as:▷How various systems in your vehicle were
operating.▷Whether or not the driver and passenger
safety belts were fastened.▷How far, if at all, the driver was depressing
the accelerator and/or brake pedal.▷How fast the vehicle was traveling.
These data can help provide a better under‐
standing of the circumstances in which
crashes and injuries occur.
EDR data are recorded by your vehicle only if a
nontrivial crash situation occurs; no data are
recorded by the EDR under normal driving
conditions and no personal data, e.g., name,
gender, age, and crash location, are recorded.
However, other parties, such as law enforce‐
ment, could combine the EDR data with the
type of personally identifying data routinely ac‐
quired during a crash investigation.
To read data recorded by an EDR, special
equipment is required, and access to the vehi‐
cle or the EDR is needed. In addition to the ve‐
hicle manufacturer, other parties, such as law
enforcement, that have the special equipment,
can read the information if they have access to
the vehicle or the EDR.
Vehicle identification
number
The vehicle identification number can be found
in the engine compartment.
The vehicle identification number can also be
found behind the windshield.
Reporting safety defects
For US customers The following only applies to vehicles owned
and operated in the US.
If you believe that your vehicle has a defect
which could cause a crash or could cause in‐
jury or death, you should immediately inform
the National Highway Traffic Safety Adminis‐
tration NHTSA, in addition to notifying BMW of
North America, LLC, P.O. Box 1227, West‐

System limits
Detection of objects
Very low obstacles as well as high, protruding
objects such as ledges may not be detected by
the system.
Assistance functions also take into account
data of the PDC.
Follow instructions in the PDC chapter, refer to
page  125.
The objects displayed on the Control Display
under certain circumstances are closer than
they appear. Do not estimate the distance from
the objects on the display.
Parking assistant The concept
The system supports parking in the following
situations:▷When parking parallel to the road.▷When reverse parking diagonally 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 and instructions issued
by the PDC, the parking assistant and the rear‐
view camera and react accordingly.
A component of the parking assistant is the
PDC Park Distance Control, refer to page  125.
Hints Personal responsibility
Even an active system does not relieve
the driver from personal responsibility while
driving.
Technically the system has its limits, it cannot
independently react to all traffic situations.
Monitor your driving, be on the alert, observe
the vehicle surroundings and other traffic and
react when needed - risk of accident.◀
Changes to the parking space
Changes to the parking space after it was
measured are not taken into account by the
system.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the risk of an acci‐
dent.◀
Transporting cargo
Cargo that extends beyond the perimeter
of the vehicle is not taken into account by the
system during the parking procedure.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the risk of an acci‐
dent.◀
