Component Identification
Prior to starting a journey during the cold season the stationary heater (STH) ensures that:
^
the passenger compartment is preheated,
^
the windows are free of ice and condensation,
^
the engine is preheated.
The use of a stationary heater (SH) helps to reduce:
^
the risk of an accident by providing excellent vision before starting out on a trip,
^
the mechanical wear to the automotive engine associated with a cold start,
^
fuel consumption and at the same time it also helps to preserve environmental resources by cutting down the pollutants in exhaust emissions when
starting up a previously heated engine.
