or deactivates only front parking
assist.
● If reverse gear is selected, a brief
press activates or deactivates
front and rear parking assist.
Activation
The system is activated automatically
at a speed up to 7 mph.
An illuminated LED in the parking
assist button D indicates that the
system is ready to operate.
If D is switched off within an ignition
cycle, the front parking assist is
deactivated. If vehicle speed has
exceeded 15 mph beforehand,
parking assist will be reactivated when speed drops below 7 mph.
When the system is deactivated, the
LED in the button extinguishes and
Park Assist Off pops-up in the Driver
Information Centre.
Indication
The system warns the driver with
acoustic signals against potentially
hazardous obstacles in front of thevehicle in a distance range up to 80
cm and against potentially hazardous
obstacles behind the vehicle in a
distance range up to 1.5 metres.
Depending on which side of the
vehicle is closer to an obstacle, you
will hear acoustic warning signals in the vehicle on the respective side.
The interval between the sounds
becomes shorter as the vehicle gets
closer to that obstacle. When the
distance is less than approx. 30 cm,
the sound is continuous.
Additionally, the distance to obstacles is shown in the Driver Information
Centre 3 88 or, depending on the
version, on the Colour-Info-Display
3 93.
The distance to a front and rear
obstacle is displayed by changing
distance lines in the Driver
Information Centre.
The distance indication can be
inhibited by vehicle messages with a
higher priority. After dismissing the
message distance indication appears again.

Advanced parking assist9 Warning
The driver bears full responsibility
for accepting the parking slot
suggested by the system and the
parking manoeuvre.
Always check the surrounding
area in all directions when using
the advanced parking assist.
The advanced parking assist
measures a suitable parking slot
while passing, calculates the
trajectory and automatically steers
the vehicle into a parallel or
perpendicular parking slot.
Instructions are given in the Driver
Information Centre 3 88 or,
depending on the version, on the
Colour-Info-Display 3 93, supported
by acoustic signals.
The driver must control acceleration,
braking and gearshifting, while
steering is done automatically.
Advanced parking assist can only be activated when driving forwards.
150Driving and operatingDisplay priorities

be continued.
Deactivation
The system is deactivated by:
● a long press of D
● parking manoeuvre successfully ended
● driving faster than 18 mph during
parking slot search
● driving faster than 5 mph during parking guidance
● driver interference on steering wheel detected
● exceeding the maximum number
of gear changes: eight parking
cycles when parallel parking or
five cycles when perpendicular
parking
● switching off the ignitionDeactivation by the driver or by the
system during manoeuvring will be indicated by Parking Deactivated on
the display. Additionally, an acoustic
signal sounds.
Fault
A message appears when:
● there is a fault in the system
● the driver did not successfully complete the parking manoeuvre
● the system is not operational
● any of the deactivation reasons described above apply
If an object is detected during parking instructions, Stop is indicated on the
display. Removing the object will
resume the parking manoeuvre. If the
object is not removed, the system will
be deactivated. A long press of D
will activate the system and search for
a new parking slot.Basic notes on parking assist
systems9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.
Special attention must be paid to
low obstacles which can damage
the lower part of the bumper.
Caution
Performance of the system can be reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
system can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles in the vicinity
(e.g. off-road vehicles, mini vans,
vans). Object identification and
154Driving and operatingPressing LPG switches between
petrol and liquid gas operation as
soon as the required parameters (coolant temperature, gas
temperature and minimum engine
speed) have been reached. The
requirements are usually fulfilled after
approx. 60 seconds (depending on
exterior temperature) and the first firm press on the accelerator. The LED

or failure in liquid gas
system. A message is
displayed in the Driver
Information Centre.
If the fuel tank is empty, the engine
will not start.
The selected fuel mode is stored and reactivated at the next ignition cycle if
conditions allow.
As soon as the liquid gas tanks are
empty, petrol operation is
automatically engaged until the
ignition is switched off.
When switching automatically
between petrol or gas operation, a
brief delay of engine tractive power
may be noticeable.
Every six months, run the petrol tank
down until control indicator Y
illuminates, then refuel. This helps
maintain fuel quality and system
function for petrol operation.
Fill the tank completely at regular
intervals to prevent corrosion in the
tank.
Faults and remedies
If gas mode is not possible, check the following:
● Is there enough liquid gas present?
● Is there enough petrol present for
starting?Due to extreme temperatures in
combination with the gas
composition, it may take slightly
longer before the system switches
from petrol to gas mode.
In extreme situations, the system may
also switch back to petrol mode if the
minimum requirements are not
fulfilled. If conditions allow, it might be
possible to manually switch back to
liquid gas operation.
Seek the assistance of a workshop in the event of all other faults.Caution
Repairs and adjustments may onlybe made by trained specialists in
order to maintain the safety and
warranty on the LPG system.
Liquid gas is given a particular odour
(odorised) so that any leaks can be
detected easily.
