Always switch off the additional heating when filling up with fuel, to prevent any risk of fire or explosion.
To avoid any risk of intoxication or asphyxiation, the additional heating must not be used, even for short periods, in an enclosed area such as a garage or workshop not equipped with a system for the extraction of exhaust gases.
Do not park the vehicle over inflammable materials (e.g. dry grass, dead leaves or paper) as this could present a fire risk.
The programmable heating system is supplied by the vehicle’s fuel tank. Before use, ensure that the remaining fuel level is sufficient. If you are using the reserve fuel tank, we strongly advise you not to use the programmable heating system.
