Driving and operating147Activation
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) even in
the parking assist mode. A long press
of D activates advanced parking
assist to start parking manoeuvre.
The system can only be activated at
a speed up to 18 mph and the system searches for a parking slot at a speed
up to 18 mph.
The maximum allowed parallel
distance between the vehicle and a
row of parked cars is 1.8 metres for
parallel parking and 2.5 metres for
perpendicular parking.
FunctionalityParking slot searching mode
Select parallel or perpendicular
parking slot in Driver Information
Centre by pressing SET/CLR.

Driving and operating153Full function of the LPG system can
only be guaranteed with liquid gas
which complies with the minimum
requirements of DIN EN 589.
Fuel selector
Pressing 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

five

and
extin‐
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.
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.

186Vehicle care6. 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 activate
the 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 beenmatched 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 87.
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
indicators (TWI). Their position is
indicated by markings on the
sidewall.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 years.
Changing tyre and wheel size
If tyres of a different size than those
fitted at the factory are used, it may be necessary to reprogramme the
