2003 BUICK LESABRE coolant level

Notice:
·When using concentrated washer ¯uid, follow
the manufacturer's instructions for adding
water.
·Don't mix water with ready-to-use washer ¯uid.
Water can cause the solution to freeze and
damage your washer ¯uid tank and other parts
of the washer system. Also, water doesn't
clean as well as washer ¯uid.
·Fill your washer ¯uid tank only three-quarters
full when it's very cold. This allows for
expansion if freezing occurs, which could
damage the tank if it is completely full.
·Don't use engine coolant (antifreeze) in your
windshield washer. It can damage your
washer system and paint.
Brakes
Brake Fluid
Your master cylinder reservoir is ®lled with DOT-3 brake
¯uid. SeeEngine Compartment Overview on page 5-12for the location of the reservoir.
There are only two reasons why the brake ¯uid level in
the reservoir might go down. The ®rst is that the
brake ¯uid goes down to an acceptable level during
normal brake lining wear. When new linings are put in,
the ¯uid level goes back up.
