Hello and welcome, on the DIC there should a option for turning the remote start on or off, also even if the remove start is on, there can be several reasons why the remote start is not working.
To avoid excessive drain on the battery, it is recommended that the headlamps are turned off.
If the vehicle is not in P (Park), PERSONAL PROGRAM ONLY IN PARK will display.
If the vehicle is not able to enter the personal program menu, PERSONAL PROGRAM NOT AVAILABLE will display.
Press the menu button to display the modes that are available to program.
Press the set/reset button to change the setting of each mode.
If your vehicle has remote start, this feature allows the remote start to be turned OFF or ON. The remote start feature allows you to start the engine from outside of the vehicle using the RKE transmitter. Press the menu button until REMOTE START appears on the DIC display. Press the set/reset button to scroll through the following choices:
OFF: The remote start feature will be disabled. ON (default): The remote start feature will be enabled.
To select a setting and move on to the next feature, press the menu button while the desired setting is displayed on the DIC.
