Coolant temperature display
Coolant temperature gauge. For physical reasons, the engine
temperature gauge shows the coolant
temperature only if the coolant level is
adequate.
During operation the system is pressurised.
The temperature may therefore rise briefly
to over 100 C.

Control indicator Y illuminates when the
level is low. Refuel immediately if the
control indicator begins to flash.
Never run the tank dry!
Because of the fuel remaining in the tank,
the amount of fuel required to fill the tank
may be less than the specified tank

112 Driving and operationCorrect filling depends to a large extent on
proper operation of the fuel dispensing
pump:
1. Fully insert the pump nozzle and switch it
on.
2. After the automatic cut-off, the nominal
capacity of the fuel tank can be
obtained by topping up with two doses
of fuel. Make sure the nozzle is fully
inserted.
To close, place fuel filler cap in position and
turn, overcoming the resistance until the
ratchet on the cap engages audibly. Lock
the fuel filler cap with the ignition key 3.
Close fuel tank cover. Refuelling, natural gas 3
The fuel tank filler neck for natural gas and
petrol is located on the right rear side of the
vehicle.
Picture no: 12292t.tif
Remove the cap from the natural gas filler
neck.
The tank action must be fully completed,
e.g. bleeding the filler neck.
After refuelling, refit the cap. Caution
Wipe off any overflowing fuel
immediately.
9 Warning
Care must be taken when handling
natural gas!
Before refuelling, be sure to switch off
the engine and any auxiliary heater with
combustion chamber.
Natural gas is flammable and explosive.
Therefore, avoid naked flames and
sparks when handling or in the vicinity of
natural gas. Do not smoke! This also
applies where natural gas can only be
detected by its characteristic smell.
If there is a smell of natural gas in the
vehicle, have cause established
immediately by a workshop that is
authorised to maintain natural gas
vehicles and have the problem
remedied.
9 Warning
When refuelling vehicles with natural
gas, be sure to follow the operational
and safety regulations of the filling
station.
The gas tank must only be replenished
at filling stations that refuel with
temperature compensation with a
maximum output pressure of 250 bar.
