Brake Pedal Travel See your dealer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign of brake trouble. Battery Your new vehicle comes with a maintenance free ACDelco@battery. When it's 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. Brake Adjustment Every time you apply the brakes, with or without the vehicle moving, your brakes adjust for wear. Replacing Brake System Parts The braking system on a vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. Your vehicle was designed and tested with top-quality GM brake parts. When you replace parts of your braking system - for example, when your brake linings wear down and you need new ones put in - be sure you get new approved GM replacement parts. If you don't, your brakes may no longer work properly. For c~cu p c , ll ~,,,,-nln :4 11 DUI I IGUI I C _------ put3 -..4- :- 11 I i-,,,1
