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 107.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.◀

Maintenance
BMW Maintenance System
The maintenance system directs you to re‐
quired
maintenance measures and thereby sup‐
ports you in maintaining road safety and the op‐
erational reliability of the vehicle.
Condition Based Service CBS
Sensors and special algorithms take into ac‐
count the driving conditions of your vehicle.
Based on this, Condition Based Service deter‐
mines the maintenance requirements.
The system makes it possible to adapt the
amount of maintenance you need to your user
profile.
Details on the service requirements, refer to
page 81, can be displayed on the Control Dis‐
play.
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 and Warranty
Information Booklet for US
models and Warranty and
Service Guide Booklet for
Canadian models
Please
consult your Service and Warranty Infor‐
mation Booklet for US models and Warranty and
Service Guide Booklet for Canadian models for
additional information on service requirements.
Maintenance and repair should be performed by
your service center. Make sure to have regular
maintenance procedures recorded in the vehi‐
cle's Service and Warranty Information Booklet
for US models, and in the Warranty and Service
Guide Booklet for Canadian models. These en‐
tries are proof of regular maintenance.
Socket for OBD Onboard
Diagnosis There is an OBD socket on the driver's side for
checking

the primary components in the vehicle
emissions.
Emissions
▷The warning lamp lights up:
Emissions are deteriorating. Have
the

vehicle checked as soon as pos‐
sible.
▷ The warning lamp flashes under cer‐
tain circumstances: Seite 241

Care
Car washes
Notes
Steam jets or high-pressure washers
When using steam jets or high-pressure
washers, hold them a sufficient distance away
and use a maximum temperature of 140 ℉/
60 ℃.
Holding them too close or using excessively
high
pressures or temperatures can cause dam‐
age or preliminary damage that may then lead to
long-term damage.
Follow the operating instructions for the high-
pressure washer.◀
Cleaning sensors/cameras with high-
pressure washers
When using high-pressure washers, do not
spray the exterior sensors and cameras, e.g.,
Park Distance Control*, for extended periods of
time and only from a distance of at least 12 in/
30 cm.◀
Wash your vehicle frequently, particularly in win‐
ter.
Intense soiling and road salt can damage the ve‐
hicle.
Washing in automatic car washes
Your vehicle can be washed in automatic car
washes right from the start.
Give preference to cloth car washes or those
that use soft brushes in order to avoid paint
damage.
Notes
Note the following:
▷ Make sure that the wheels and tires are not
damaged by the transport mechanisms.
▷ Fold in the exterior mirrors; otherwise, they
may

be damaged, depending on the width of
the vehicle. ▷
Deactivate the rain sensor, refer to page 70,
to avoid unintentional wiper activation.
▷ Do not treat the convertible top with wax.
Ensure that a cycle without wax or a special
cycle for convertibles is available.
▷ In some cases, an unintentional alarm can be
triggered

by the interior motion sensor of the
alarm system*. Follow the instructions on
avoiding an unintentional alarm, refer to
page 43.
Guide rails in car washes
Avoid car washes with guide rails higher
than 4 in/10 cm; otherwise, the vehicle body
could be damaged.

◀

steps are taken:
Manual transmission:
1. Shift to neutral.
2. Release the parking brake, refer to page 67.
