COLD WEATHER STARTING

When starting a cold engine, the intake air will be
warmed up with the intake air preheater. Turn the
ignition switch to the ON position. The intake air
preheater will not engage at coolant temperature

below 54°F (12°C), the intake air preheater will
engage and will light the preheater telltale

engine coolant temperature. Wait before the
preheater telltale has turned off before starting
the engine.
