140Driving and operating
Button logic operates the systems by
pressing 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, long press activates
advanced parking assist.
■ If only advanced parking assist is active, a brief press activates front-
rear parking assist.
■ If only advanced parking assist is active, long press deactivates
advanced parking assist.
■ If forward gear or neutral is selected, a brief press activates ordeactivates only front parking
assist.
■ If reverse gear is selected, a brief press activates or deactivates frontand rear parking assist.Activation
When searching for a parking slot, the
system is ready to operate with a long press of button D.
The system recognises and
memorises (10 metres for parallel
parking slots or 6 metres for
perpendicular parking slots) even in
the parking assist mode. Long press
of button 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.

Driving and operating147
Pressing the LPG button 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 illuminates=liquid gas
operationLED flashes=no switching is
possible, one type
of fuel is empty
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.
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.
9 Warning
If you smell gas in the vehicle or in
the immediate vicinity, switch to petrol mode immediately. No
smoking. No naked flames or
ignition sources.
If the gas odour persists, do not start
the engine. Have the cause of the
fault remedied by a workshop.
When using underground car parks,
follow the instructions of the operator
and local laws.
Notice
In the event of an accident, switch off
the ignition and lights.

3. Use the MENU button on the turn
signal lever to select the Vehicle
Information Menu in the Driver
Information Centre (DIC).
4. Turn the adjuster wheel to scroll to
the tyre pressure menu.
5. Press the SET/CLR button to
begin the sensor matching
process. A message requesting
acceptance of the process should
display.
6. Press the SET/CLR button again
to confirm the selection. The horn sounds twice to signal the
receiver is in relearn mode.
7. Start with the left side front tyre.
8. Place the relearn tool against the tyre sidewall, near the valve stem.Then press the button to activate
the TPMS sensor. A horn chirp
confirms that the sensor
identification code has been
matched to this tyre and wheel
position.
9. Proceed to the right side front tyre,
and repeat the procedure in
Step 8.10. Proceed to the right side rear tyre,
and repeat the procedure in
Step 8.
11. Proceed to the left side rear tyre, and repeat the procedure in
Step 8. The horn sounds twice to
indicate the sensor identification
code has been matched to the left
side rear tyre, and the TPMS
sensor matching process is no
longer active.
12. Turn off the ignition.
13. Set all four tyres to the recommended air pressure level
as indicated on the tyre pressure
label.
14. Ensure the tyre loading status is set according selected pressure
3 89.
Temperature dependency Tyre pressure depends on the
temperature of the tyre. During
driving tyre temperature and pressure increase.The tyre pressure value displayed in
the Driver Information Centre shows
the actual tyre pressure. Therefore it
is important to check tyre pressure
with cold tyres.
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.
