Remote Start System Behavior

When the remote start feature is used, the climate control system automatically sets certain parameters in an attempt to achieve a comfortable cabin temperature. These parameters are set based on outside air temperature. During remote start, the outside air temperature is continually evaluated and HVAC system behavior can change if the outside air changes between cold, moderate and warm temperatures.

For cold ambient air temperatures as determined by the HVAC module AUTO mode to request heat:

• the airflow mode is set to FLOOR/DEFROST.
• the temperature is set to 22°C (72°F).
• the blower speed is set to AUTO.
• the air inlet mode is set to AUTO.
• the auxiliary electric heater is enabled if needed (diesel engines only).

For moderate ambient air temperatures as determined by the HVAC module AUTO mode to request heat or cooling:

• the airflow mode is set to the AUTO.
• the temperature is set to the last user setting (Temperature setting is limited to 18°C (65°F) minimum and 29°C (85°F) maximum. If the temperature is set above or below that range, it will use the minimum or maximum value.).
• the blower speed is set to the AUTO.
• the air inlet mode is set to AUTO.
• the auxiliary electric heater is enabled if needed (diesel engines only).

For warm ambient air temperatures as determined by the HVAC module AUTO mode to request cooling:

• the airflow mode is set to AUTO.
• the temperature is set to 22°C (72°F).
• the blower speed is set to AUTO.
• the air inlet mode is set to AUTO.
• the auxiliary electric heater is not enabled (diesel engines only).
