166Driving and operatingCaution
Use of fuel that does not comply toEN 590 or similar can lead to
engine powerloss, increased wear
or engine damage.
Do not use marine diesel oils, heating
oils, Aquazole and similar diesel-
water emulsions. Diesel fuels must
not be diluted with fuels for petrol
engines.
Fuel for liquid gas operation Liquid gas is known as LPG
(Liquefied Petroleum Gas) or under its French name GPL (Gaz de Pétrole
Liquéfié). LPG is also known as
Autogas.
LPG consists mainly of propane and
butane. The octane rating is between 105 and 115, depending on the
butane proportion. LPG is stored as a
liquid at a pressure of approx. five to
ten bar.
The boiling point depends on the
pressure and the mixing ratio. At
ambient pressure, it is between
-42 °C (pure propane) and -0.5 °C
(pure butane).Caution
The system works at an ambient
temperature of approx. -8 °C to
100 °C.
Full functioning 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 status

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 signal 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 tyre and 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 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sensor matching process is no
longer active.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 pressure
information label.
15. Ensure the tyre loading status is set according to the selected tyre
pressure 3 96.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
