Low objects already displayed, e.g., curbs, can
move into the blind area of the sensors before
or after a continuous tone sounds.
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 with
ice.▷When sensors are covered in snow.▷On rough road surfaces.▷On uneven surfaces, such as speed bumps.▷In large buildings with right angles and
smooth walls, e.g., in underground garages.▷In automatic car washes.▷Through heavy pollution.▷Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.
The malfunction is signaled by a continuous
tone alternating between the front and rear
speakers. As soon as the malfunction due
to other ultrasound sources is no longer
present, the system is again fully functional.
Malfunction
A Check Control message, refer to page 63, is
displayed in the instrument cluster.
PDC has failed. Have the system checked.
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 possi‐
ble 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 react accordingly.
A component of the parking assistant is the
PDC Park Distance Control, refer to page 108.
Information WARNING
The system does not relieve from the per‐
sonal responsibility to correctly assess the traf‐
fic situation. Based on the limits of the system,
it cannot independently react to all traffic situa‐
tions. There is risk of an accident. Adjust the
driving style to the traffic conditions. Watch
traffic closely and actively interfere in the re‐
spective situations. ◀
CAUTION
The parking assistant can steer the vehi‐
cle over or onto curbs. There is risk of property
damage. Watch traffic closely and actively in‐
terfere in the respective situations. ◀

The Coasting driving condition is enabled under
certain conditions.
Under certain conditions the engine is auto‐
matically decoupled from the transmission in
selector lever position D. The vehicle continues
traveling with the engine idling to reduce fuel
consumption. Selector lever position D remains
engaged. An indicator provides information
about the distance traveled in Coasting mode.
In addition, context-sensitive instructions are
displayed to assist with an optimized fuel con‐
sumption driving style.
The achieved extended range is displayed in
the instrument cluster.
Overview The system includes the following MINIMAL
functions and displays:▷GREEN bonus range, refer to page 144.▷GREEN tips driving instruction, refer to
page 145.▷GREEN climate control, refer to page 144.▷Coasting driving condition, refer to

displayed in the instrument clus‐
ter.
Configuring GREEN mode

Configure the program.
GREEN tip
"GREEN speed warning":
Displays a reminder when the set GREEN mode
speed is exceeded.
GREEN climate control
"GREEN climate control":
Climate control is set to be fuel-efficient.
By making a slight change to the set tempera‐
ture, or adjusting the rate of heating or cooling
of the car's interior fuel consumption can be
economized.
The outputs of the seat heater and the exterior
Additionally heat output to seats and exterior
mirror is reduced.
Exterior mirror heat is available when outside
temperatures are very low.

Fuel-efficiency can be optimized by disengag‐
ing the engine and Coasting, refer to page 145,
with the engine idling.
This function is only available in GREEN mode.

GREEN bonus range An adjusted driving style helps
you extend your driving range.
This may be displayed as the bo‐
nus range in the instrument clus‐
ter.
The bonus range is shown in the range display.

The display switches to green as soon as all
conditions for fuel-efficiency-optimized driving
are met.
GREEN tip driving instruction
Instructions tell you to switch to a more fuel-ef‐
ficient driving style when you back off the ac‐
celerator.

Coasting
The concept
The system helps to conserve fuel.
To do this, under certain conditions the engine
is automatically decoupled from the transmis‐
sion when selector lever position D is set. The
vehicle continues traveling with the engine
idling to reduce fuel consumption. Selector
lever position D remains engaged.
This driving condition is referred to as coasting.
As soon as the brake or accelerator pedal is de‐
pressed, the engine is automatically coupled to
the transmission again.
Information Coasting is a component of the GREEN driving
mode, refer to page 143.
Coasting is automatically activated when
GREEN mode is called via the Driving Dynamics
Control, refer to page 99.

The function is available in a certain speed
range.
A proactively driving style helps the driver to
use the function as often as possible and sup‐
ports the fuel-conserving effect of coasting.
Safety mode
The function is not available under one of the
following conditions.▷DSC OFF or TRACTION activated.▷Driving in the dynamic limit range and on
steep uphill or downhill grades.▷Battery charge status temporarily too low
or vehicle electrical system drawing exces‐
sive current.▷Cruise control activated.
Functional requirements
In GREEN mode, this function is available in a
speed range from approximately 30 mph, ap‐
prox. 50 km/h to 100 mph, approx. 160 km/h,
if the following conditions are met:
▷Accelerator pedal and brake pedal are not
operated.▷The selector lever is in selector lever posi‐
tion D.▷Engine and transmission are at operating
temperature.
Display

e.g., to use the braking effect of the engine
when traveling downhill.1. "Settings"2.Select between "Driving mode" or "GREEN

Take care not to add too much engine oil.CAUTION
Too much engine oil can damage the en‐
gine or the catalytic converter. There is risk of
property damage. Do not add too much engine
oil. Have too much engine oil siphoned off by a
dealer’s service center or another qualified
service center or repair shop. ◀
Detailed measurement
The concept
In the detailed measurement the engine oil
level is checked and displayed via a scale.
If the engine oil level reaches the minimum
level, a check control message is displayed.
During the measurement, the idle speed is in‐
creased somewhat.
Requirements▷Vehicle is on level road.▷Manual transmission: shift lever in neutral
position, clutch and accelerator pedals not
depressed.▷Steptronic transmission: selector lever in se‐
lector lever position N or P and accelerator
pedal not depressed.▷Engine is running and is at operating tem‐
perature.
Performing a detailed measurement
In order to perform a detailed measurement of
the engine oil level:
Confirm message regarding engine oil level dis‐ play.
The engine oil level is checked and displayed
via a scale.
Time: approx. 1 minute.
Adding engine oil
Information CAUTION
A too low engine oil level causes engine
damage. There is risk of property damage.
Add engine oil within the next
125 miles/200 km. ◀
CAUTION
Too much engine oil can damage the en‐
gine or the catalytic converter. There is risk of
property damage. Do not add too much engine
oil. Have too much engine oil siphoned off by a
dealer’s service center or another qualified
service center or repair shop. ◀
WARNING
Operating materials, e.g. oils, greases,
coolants, fuels, can contain harmful ingredi‐
ents. There is risk of injuries or danger to life.
Observe the instructions on the containers. Avoid the contact of articles of clothing, skin or
eyes with operating materials. Do not refill op‐
erating materials into different bottles. Store
operating materials out of reach of children. ◀
General information
Only add engine oil when the message is dis‐
played in the instrument cluster. The quantity
to be added is indicated in the message dis‐
played in the instrument cluster.
Switch off the ignition and safely park the vehi‐
cle before engine oil is added.
