Always switch off the programmable heater while refuelling to avoid any risk of fire or explosion.

To avoid the risk of poisoning and asphyxiation, the programmable heater must not be used, even for short periods, in enclosed spaces such as garages or workshops that are not equipped with an exhaust gas extraction system.

Do not park the vehicle on a flammable surface (dry grass, dead leaves, paper, etc.); there is a risk of fire.

The programmable heating system is supplied from the vehicle's fuel tank.

Before use, make sure there is enough fuel remaining. If the fuel tank is on reserve, we strongly recommend not programming the heater.
