Air Conditioning

SD DM 07.00.03

The air conditioner cools and dehumidifies the air inside the cab. Press the air-conditioning button to turn the air conditioner ON and OFF. See Fig..

  1. Amber Indicator

Fig. 1,  Air-Conditioning Button

When the A/C is operating, the amber indicator on the air-conditioning button will be illuminated regardless of whether the request for A/C comes from the cab climate-control panel, or the sleeper climate-control panel. When the instrument panel lights are on, the snowflake indicator on the air-conditioning button will be illuminated.

The A/C will automatically disable when the outside-air temperature is low enough to make air conditioning ineffective, or conditions exist that put the HVAC system into protection mode.
