2008 Cadillac Escalade ESV Owner's Manual - Page 107

After your vehicles engine has been started two times using the remote vehicle start button, or a single remote start with one time extension, 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 and the check engine light comes on. 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 on page 3-61 for additional information. 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/retailer to add the manufacturer's remote vehicle start feature. If your vehicle has the remote start ready feature, your RKE transmitter will have extended range that will allow you to lock or unlock your vehicle from approximately 197 feet (60 m) away. See your dealer/retailer if you would like to add the manufacturer's remote vehicle start feature to your vehicle. 2-9
