Operation
Things to note
If the v ehicl
e is left parked for a long time im-
mediately after refuelling, the natural gas lev-
el indicator may not accurately indicate the
same level shown after refuelling when the
vehicle is started up again. This is not due to a
leak in the system, but to a drop in pressure in
the gas tank for technical reasons after a
cooling phase just after refuelling. Note
In vehicles with natural gas engines, the
petr ol t
ank fuel level gauge may display
the refuelled amount with a slight delay
(depending on the refuelled amount). Engine coolant temperature indica-

Some contr ol and w
arning lamps come on
when the ignition is switched on, and switch
off when the engine starts running, or while
driving.
Depending on the model, additional text
messages may be viewed on the instrument
panel display. These may be purely informa-
tive or they may be advising of the need for
action ››› page 68, Instrument panel
.
Depending upon the equipment fitted in the
vehicle, instead of a warning lamp, some-
times a symbol may be displayed on the in-
strument panel.
When certain control and warning lamps are
lit, an audible warning is also heard. Red warning lamps
