Start-Stop Function - Seat ALTEA Owner's Manual

Note
● The LPG system must be subject to regular inspections at a specialised
workshop in accordance with the Maintenance Programme.
● The engine is always started with petrol, even when LPG was being used
when it was switched off. For this reason the tank should never be drained
of petrol completely.
● If frequent short journeys are made, especially when the outside tem-
perature is low, the vehicle will tend to run on petrol more often than on
LPG. Therefore, the petrol tank may empty before the LPG tank.
● If while you are driving the system switches automatically to the petrol
operating mode because the LPG tank is almost empty, the next few times
the engine starts up, and according to the outside temperature and driving
style, it may switch briefly to LPG operating mode to use up what is left in
the tank.
● When the system switches automatically to the petrol operating mode
because the LPG tank is almost empty, you can revert to gas operating
mode by pressing the button
low acceleration. This procedure can be repeated several times while driv-
ing with precaution until all the LPG left in the tank has been used up.
● Vehicles that can display information or warning messages on the dash-
board may show information related to LPG.
