Climate Control System
The heating, cooling, and ventilation for the vehicle can be controlled with this system.
For vehicles with the remote start feature, when activated, the climate control system heats or cools the inside of the vehicle with the settings used before the vehicle was turned off. The heated seats, if the vehicle has them, and the rear window defogger will also be turned on when it is cold outside. The cooled seat setting is not activated during a remote start. Normal operation of the system will return after the key is turned to the ON/RUN position. See Remote Keyless Entry (RKE) System Operation for more information.
