Park Distance Control PDC
The concept
In addition to the PDC Park Distance Control, the
backup camera, refer to page 102, can be
switched on.
PDC supports you when parking. A slow ap‐
proach to an object in front of or behind your ve‐
hicle is announced by:▷Signal tones.▷Visual display.
Measurement
Measurements are made by ultrasound sensors
in the bumpers.
The range is approx. 6 ft/2 m.
An acoustic warning is first given:
▷By the front sensors and two rear corner
sensors at approx. 24 in/60 cm.▷By the rear middle sensors at approx.
5 ft/1.50 m.
System limits
Check the traffic situation as well
PDC cannot serve as a substitute for the
driver's personal judgment of the traffic situa‐
tion. Check the traffic situation around the vehi‐
cle with your own eyes. Otherwise, an accident
could result from road users or objects located
outside of the PDC detection range.
Loud noises from outside and inside the vehicle
may prevent you from hearing the PDC's signal
tone.◀
Avoid driving quickly with PDC
Avoid approaching an object quickly.
Avoid driving away quickly while PDC is not yet
active.
For technical reasons, the system may other‐
wise be too late in issuing a warning.◀
Limits of ultrasonic measurement
The detection of objects can reach the physical
limits of ultrasonic measurement, for instance:▷With tow bars and trailer hitches.▷With thin or wedge-shaped objects.▷With low objects.▷With objects with corners and sharp edges.
Low objects already displayed, e.g., curbs, can
move into the blind area of the sensors before or
after a continuous tone sounds.
High, protruding objects such as ledges may not
be detected.
False warnings
PDC may issue a warning under the following
conditions even though there is no obstacle
within the detection range:
▷In heavy rain.▷When sensors are very dirty or covered in
ice.▷When sensors are covered in snow.▷On rough road surfaces.▷In large buildings with right angles and
smooth walls, e.g., in underground garages.▷In heavy exhaust.▷Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.
Switching on automatically
With the engine running or the ignition switched
on, shift the selector lever into position R.
Switching off automatically when
driving forward
The system switches off when a certain distance
or speed is exceeded.
Switch on the system again if necessary.

Malfunction
A Check Control message, refer to page 77, is
displayed in the instrument cluster.
The areas in front of and behind the vehicle ap‐
pear in shaded form on the Control Display. PDC
has failed. Have the system checked.
To ensure full operability:
▷Keep the sensors clean and free of ice.▷When using high-pressure washers, do not
spray the sensors for long periods and main‐
tain a distance of at least 12 in/30 cm.
Rear view camera
The concept
The rear view camera assists you when parking
and maneuvering in reverse. To accomplish this,
the region behind your vehicle is shown on the
Control Display.
System limits Check the traffic situation as well
Check the traffic situation around the ve‐
hicle with your own eyes. Otherwise, an accident
could result from road users or objects located
outside the picture area of the backup camera. ◀
Detection of objects
High, protruding objects such as ledges
may not be detected by the backup camera.◀
Switching on automatically
With the engine running or the ignition switched
on, shift the selector lever into position R.
The image of the rear view camera is displayed
when the system has been switched on using
iDrive.
Switching off automatically when
driving forward
The system switches off when a certain distance
or speed is exceeded.
Switch on the system again if necessary.
Switching on/off manually
Press the button.
▷On: the LED lights up.▷Off: the LED goes out.
If PDC is displayed, switch on the backup cam‐
era via the iDrive, refer to page 101.

Risk of damage
Before opening the hood, ensure that the
wiper arms with wiper blades are folded onto the
window; otherwise, damage may occur.◀1.Pull the lever.2.Lift the hood all the way.3.Press the release handle and open the hood.
Closing the hood
Drop the hood from a height of ap‐
prox. 16 in/40 cm. It must be clearly heard to en‐
gage.
Hood open when driving
If you see any signs that the hood is not
completely closed while driving, pull over imme‐
diately and close it securely.◀
Danger of pinching
Make sure that the closing path of the
hood is clear; otherwise, injuries may result.◀
Engine oil
General information
Engine oil consumption depends on the driving
style and the conditions of use. A highly sporty
driving style, for example, results in considerably
higher engine oil consumption.
Therefore, regularly check the engine oil level
after refueling.
Checking the engine oil level
Your car is equipped with an electronic engine
oil level check.
Requirements▷The engine must be running and warm after
the vehicle has been driven for at least
6.2 miles/10 km.▷The vehicle is stopped or being driven on a
level roadway.

Oil change
An oil change should be carried out by the serv‐
ice center only.
Coolant
General information Danger of burns from hot engine
Do not open the cooling system while the
engine is hot; otherwise, escaping coolant may
cause burns.◀
Suitable additives
Only use suitable additives; otherwise, en‐
gine damage may occur. The additives are
harmful to your health.◀
Coolant consists of water and additives.
Not all commercially available additives are suit‐
able for your vehicle. Ask your service center for
suitable additives.
Checking the coolant level
1.Do not open the hood until the engine has
cooled down.2.Turn the expansion tank cap counterclock‐
wise slightly to allow any accumulated pres‐
sure to escape; then continue turning to
open.3.The coolant level is correct if it is between
the maximum and minimum marks in thefiller neck, refer also to the diagram next to
the filler neck.4.If the coolant is low, slowly add coolant up to
the specified level; do not overfill.5.Turn the cap until there is an audible click.6.Have the cause of the coolant loss elimi‐
nated as soon as possible.
Disposal
Comply with the appropriate environmen‐
tal protection regulations when disposing
of coolant additives.

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
On the driver's side is an OBD socket for check‐
ing the primary components in the vehicle emis‐
sions.
Emissions
▷The warning lamp lights up:
Emissions are deteriorating. Have
the vehicle checked as soon as pos‐
sible.▷The warning lamp flashes under certain cir‐
cumstances:
This indicates that there is excessive misfir‐
ing in the engine.
Reduce the vehicle speed and have the sys‐
tem checked immediately; otherwise, seri‐
ous engine misfiring within a brief period can
seriously damage emission control compo‐
nents, in particular the catalytic converter.
Display of the previously described mal‐
functions on Canadian models.
Fuel cap
The indicator lamp lights up.
If the fuel cap is not properly tightened,
the OBD system may conclude that
fuel vapor is escaping. If the cap is then tight‐
ened, the display should go out in a short time.Seite 244MobilityMaintenance244
