Auxiliary Heater
Principle of Operation
The system is designed to reduce the time needed to heat the engine when it is running. It turns on or off depending on the outside air temperature and the coolant temperature.
The system warms the engine and the vehicle interior. It uses fuel from the vehicle fuel tank.
Using the Auxiliary Heater
WARNING:
We recommend that you have a qualified technician check and repair the heater system after a crash. Failure to follow this instruction could result in personal injury or death.
WARNING:
Do not use the auxiliary heater at fuel filling stations or near sources of combustible vapors, dust or in enclosed spaces. Failure to follow this instruction could result in personal injury or death. |
The system requires a minimum of
6.1 gal (23 L) of fuel in the vehicle fuel tank and the outside air temperature has to be below
37 °F (3 °C).
Note:
The system does not operate if the battery charge level is low.
Note:
Do not use biodiesel fuel B20 as this reduces the lifetime of the heater operation.
Note:
Make sure the heater exhaust outlet, under the vehicle, under the driver compartment, is free from snow, ice, mud and any other blockages to avoid issues with the heater operation.
Note:
Driving through water can cause damage to the heater. See
Driving Through Water.
Note:
When the system is on, exhaust fumes come from under your vehicle. This is normal.
Note:
If the heater is in the process of stopping, excess fuel in the heater burns out and there is some heat, exhaust and noise.
