Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Control Components - Description & Operation: Introduction
The automatic temperature control (ATC) module controls the air conditioning (A/C) system and the heating and ventilation system to regulate the temperature, volume, and distribution of air into the cabin.
The system is a fully automatic dual zone system capable of maintaining individual temperature levels selected for the left-hand (LH) and right-hand (RH) sides of the cabin. Manual overrides for the system include intake air source, blower speed and air distribution. These selections can be made using either the Touch Screen Display (TSD) or the control switches located below the TSD.
For information on how to operate the air conditioning (A/C) system and the heating and ventilation system, refer to the Owner's Handbook.
