Here is a simple step-by-step guide to using your GMC Remote Start system:
1. Point the RKE transmitter in the direction of your vehicle.
2. Press and release the button that looks like a padlock.
3. Directly after pressing the padlock, press and hold the circular arrow button until the turn signals on your GMC vehicle begin to flash. If you are not in view of your auto, press and hold the circular arrow button for two to four seconds.
4. Your GMC vehicle has now been successfully started remotely.
