Once two remote starts, or a single remote start with one time extension has been done, the vehicle must be started with the key. After the key is removed from the ignition, the vehicle can be remote started again. The vehicle cannot be remote started if the key is in the ignition, the hood is not closed, or if there is an emission control system malfunction. Also, the engine will turn off during a remote vehicle start if the coolant temperature gets too high or if the oil pressure gets low. Vehicles that have the remote vehicle start feature are shipped from the factory with the remote vehicle start system enabled. The system may be enabled or disabled through the DIC. See "REMOTE START" under DIC Vehicle Customization (With DIC Buttons) on page 280 for additional information. If your vehicle does not have DIC buttons, see your dealer to enable or disable the remote vehicle start system.″ Remote Start Ready If your vehicle does not have the remote vehicle start feature, it may have the remote start ready feature. This feature allows your dealer to add the manufacturer's remote vehicle start feature. If your vehicle has the remote start ready feature, the RKE transmitter will have an extended range that allows locking or unlocking of the vehicle from approximately 197 feet (60 m) away. See your dealer if you would like to add the manufacturer's remote vehicle start feature to your vehicle. 121
