What to Add: When you do need brake fluid, use only DOT-3 brake fluid -- such as Delco Supreme 11@ (GM Part No. 1052535). Use new brake fluid from a sealed container only. 0 DOT-5silic your vehicle. Don't use it. Don't let someone putin the wrong kind o fluid. For example, just a few drops of mineral-based oil, such as engine in oil, your brake system can damage brake system parts so badly that they'll have to Brake fluid can damage paint, be caref so Vehicles we design and test have top-quality GM brake parts in them, as your Buick does when it is new. When you replace parts of your braking system -- for example, when your brake linings wear down and you have to have new ones put in -- be sure you get new genuine GM replacement parts. If you don't, your brakes may no longer work properly. For example, if someone puts in brake linings that are wrong for your vehicle, the balance between your front and rear brakes can change, for the worse. The braking performance you've come to expect can change in many other ways if someone puts in the wrong replacement brake parts. Battery Every new Buick has a Delco Freedoms battery. You never have to add water to one of these. When it's time for a new battery, we recommend a Delco Freedoms battery. Get one that has the catalog number shown on the original battery's label. Replacing Brake System Parts The braking system on a modern vehicle is complex. Its many parts have to beof top quality and work well together if the vehicle is to have really good braking. Vehicle Storage If you're not going to driveyour vehicle for 25 days or more, take off the black, negative (-) cable from the battery. This will help keep your battery from running down. 249
