Do not operate the auxiliary heater when refuelling the vehicle. Doing so may cause fuel vapours to combust, potentially causing a fire or explosion.
Do not operate the auxiliary heater while the vehicle is in an enclosed space. Doing so can cause a build-up of highly toxic fumes, which may cause unconsciousness or death.
The auxiliary heater is powered by fuel drawn from the vehicle's tank. The auxiliary heater operates at low ambient temperatures and helps to boost the temperature of the engine's coolant. Raising the temperature of the engine's coolant improves cabin heating and engine starting performance.
When the auxiliary heater is operating, exhaust fumes from the heater may be visible exiting from under the front of the vehicle. Exhaust fumes from the auxiliary heater are normal and are not a cause for concern.
