If you have too much brake
fluid, it can spill on the
engine. The fluid will burn
if the
engine is hot enough. You or others
could be burned, and your vehicle
could be damaged. Add brake fluid
only when work is done on the
brake hydraulic system.
? I
When your brake fluid falls to a low
level,
your brake warning light will
come on. See the Index under Brake
System Warning Light.
What to Add
When you do need brake fluid, use only
DOT-3 brake fluid-such as Deko
Supreme
11* (GM Part No. 1052535).
Use new brake fluid from a sealed
container
only.

Every new Oldsmobile has a Delco
Freedom@ battery. You never have to
add water to one of these. When it’s
time for a new battery,,+we recommend a
