Advanced parking assist is always
combined with front-rear parking assist, see previous section. Both
systems use the same sensors in the front and rear bumper.
Button D and operation logic
Advanced parking assist and front-
rear parking assist both use the same
button for activation and deactivation:
A brief press of D activates or
deactivates the parking assist.
A long press of D (approx.
one second) activates or deactivates
the advanced parking assist, see
separate description below.
Button logic operates the systems by
pressing D as follows:
● If only front-rear parking assist is active, a brief press deactivates
front-rear parking assist.
● If only front-rear parking assist is active, a long press activates
advanced parking assist.
● If only advanced parking assist is
active and the system is in
parking slot searching mode, a
brief press activates front-rear
parking assist.
● If only advanced parking assist is
active and the system is in park
guiding mode, a brief press
deactivates advanced parking
assist.
● If advanced parking assist is active, a long press deactivates
advanced parking assist and
front-rear parking assist.● If forward gear or neutral is selected, a brief press activates
or deactivates front parking
assist.
● If reverse gear is selected, a brief
press activates or deactivates
front and rear parking assist.
Activation
When searching for a parking slot, the
system is ready to operate with a long press of D.
The system recognises and
memorises ten metres for parallel
parking slots or six metres for
perpendicular parking slots in the parking assist mode.
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
status shows the current operating
mode.LED off:petrol operationLED

and

guishes:liquid gas tank is empty
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.
188Vehicle careand hold brake pedal. Move and
hold the selector lever for five
seconds in position N until P is
displayed in the Driver Information Centre. P indicates
that the sensor matching process
can be started.
On vehicles with manual
transmission: select neutral.
4. Use MENU on the turn signal
lever to select the Vehicle
Information Menu in the Driver
Information Centre.
5. Turn the adjuster wheel to scroll to
the tyre pressure menu.
6. Press SET/CLR to begin the
sensor matching process. A
message requesting acceptance
of the process should be
displayed.
7. Press SET/CLR again to confirm
the selection. The horn sounds
twice to indicate that the receiver
is in relearn mode.
8. Start with the left side front wheel.
9. Place the relearn tool against the tyre sidewall, near the valve stem.Then press the button to activatethe tyre pressure sensor. A horn
chirp confirms that the sensor
identification code has been
matched to this wheel position.
10. Proceed to the right side front wheel, and repeat the procedure
in Step 9.
11. Proceed to the right side rear wheel, and repeat the procedure
in Step 9.
12. Proceed to the left side rear wheel, and repeat the procedure
in Step 9. The horn sounds twice
to indicate that the sensor
identification code has been
matched to the left side rear
wheel, and the tyre pressure
sensor matching process is no
longer active.
13. Turn off the ignition.
14. Set all four tyres to the recommended air pressure level
as indicated on the tyre
information label.
15. Ensure the tyre loading status is set according to the selected
pressure 3 88.Tread depth
Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm (4 mm for winter tyres).
For safety reasons it is recommended
that the tread depth of the tyres on
one axle should not vary by more than 2 mm.
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
