For battery replacement, see your dealer/retailer or the service manual. To purchase a service manual, see Service Publications Ordering Information on page 8-16. 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. Infrequent Usage: If you drive your vehicle infrequently, remove the black, negative (−) cable from the battery. This will help keep the battery from running down. See "Power Window Initialization" in Power Windows on page 2-17.
