Battery Replacement Replace the battery if the KEY FOB BATT LOW message displays in the DIC. See "KEY FOB BATT LOW" under DIC Warnings and Messages on page 4‑40. Notice: When replacing the battery, do not touch any of the circuitry on the transmitter. Static from your body could damage the transmitter. 3. Insert the new battery, positive side facing up. Replace with a CR2032 or equivalent battery. 4. Snap the transmitter back together. Remote Vehicle Start Your vehicle may have a remote start feature. This feature allows you to start the engine from outside the vehicle. It may also start the vehicle's heating or air conditioning systems. When you start your vehicle using the remote start feature, the climate control system will come on and adjust the interior to the temperature settings that you left it set to when you turned the vehicle off. Laws in some communities may restrict the use of remote starters. For example, some laws may require a person using remote start to have the vehicle in view when doing so. Check local regulations for any requirements on remote starting of vehicles. Do not use the remote start feature if your vehicle is low on fuel. Your vehicle may run out of fuel. The remote start feature provides two separate starts per ignition cycle, each with 10 minutes of engine running time. To replace the battery: 1. Separate the transmitter with a flat, thin object inserted into the notch on the side. 2. Remove the old battery. Do not use a metal object. 3-6
