2009 Cadillac CTS-V Owner's Manual - Page 353

Battery This vehicle has a maintenance free battery. It is located in the trunk, behind the trim panel, on the passenger side of the vehicle. When it is time for a new battery, see your dealer/retailer for one that has the replacement number shown on the original battery's label. Warning: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling. After a power loss, such as disconnecting the battery or removing the maxi fuses in the power distribution fuse block, the following steps must be performed to calibrate the electronic throttle control. If this is not done, the engine will not run properly. 1. Turn the ignition to ON/RUN. Do not start the engine. 2. Leave the ignition in ON/RUN for at least three minutes so that the electronic throttle control will cycle and re-learn its home position. 3. Turn the ignition to LOCK/OFF. 4. Start and run the engine for at least 30 seconds. Vehicle Storage { CAUTION: Batteries have acid that can burn you and gas that can explode. You can be badly hurt if you are not careful. See Jump Starting on page 5-48 for tips on working around a battery without getting hurt. Infrequent Usage: If the vehicle is driven infrequently, remove the black, negative (−) cable from the battery. This helps keep the battery from running down. Extended Storage: For extended storage of the vehicle, remove the black, negative (−) cable from the battery or use a battery trickle charger. This helps maintain the charge of the battery over an extended period of time. 5-47
