2004 Cadillac CTS Owner's Manual - Page 330

Battery Your new vehicle comes with a maintenance free ACDelco® battery. When it is time for a new battery, get one that has the replacement number shown on the original battery's label. We recommend an ACDelco® battery. See Engine Compartment Overview on page 5-12 for battery location. 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 key to ON. Do not start the engine. 2. Leave the ignition in ON for at least three minutes so that the electronic throttle control will cycle and re-learn its home position. 3. Turn the ignition to OFF. 4. Start and run the engine for at least 30 seconds. Also, for your audio system, see Theft-Deterrent Feature on page 3-117. {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 5-45 for tips on working around a battery without getting hurt. 5-44
