Driving Backup Method of Starting: Your IA key uses a radio frequency signal to communicate with your vehicle and authorize your vehicle to start when you press the START/STOP button and apply the brake pedal. If excessive radio frequency interference is present in the area, or if the battery in your IA key is low, it may be necessary to start your car by inserting the IA key in the backup slot, located in your glove box. Insert the IA key into the slot with buttons facing out and with key ring up. After inserting the IA key into the backup slot, use the START/STOP button and brake pedal to start your vehicle as usual. The vehicle should respond normally as long as the IA key is in the backup slot in the glove box. Once the vehicle is started, the IA key can be removed from the backup slot, if desired. Fast Restart Feature: The Fast Restart feature allows you to re-start your vehicle within 20 seconds of switching the vehicle off, if a valid IA key is not present. When you switch your vehicle off without a IA key in the passenger compartment or trunk, the message RESTART NOW OR FOB IS NEEDED will be displayed on the message center. You can re-start the vehicle (by applying the brake pedal and pressing the START/STOP button) for up to 20 seconds, even though the IA key is not present. After 20 seconds have expired, you can no longer start your vehicle without the IA key present inside the vehicle. Switching the Vehicle Off when not in Park: It is recommended that you shift into the Park position before switching your vehicle off. If you switch your vehicle off with the shifter in any position other than Park, the message SHIFT TO PARK will be displayed in the message center. If the vehicle is left in this state, your key in ignition chime will activate when the driver door is opened, and you may drain your vehicle's battery. In order to avoid draining your battery, it is recommended that you always shift to park before or immediately after switching your vehicle off. 220
