Caution (Continued)
.Do not mix water withready-to-use washer fluid.Water can cause thesolution to freeze anddamage the washer fluidtank and other parts of thewasher system.
.When using concentratedwasher fluid, follow themanufacturer instructions foradding water.
.Fill the washer fluid tankonly three-quarters full whenit is very cold. This allowsfor fluid expansion iffreezing occurs, which coulddamage the tank if it iscompletely full.
Brakes
Disc brake pads have built-in wearindicators that make a high-pitchedwarning sound when the brake padsare worn and new pads are needed.The sound can come and go or can
be heard all the time when thevehicle is moving, except whenapplying the brake pedal firmly.
{Warning
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
acrash.Whenthebrakewear
warning sound is heard, have the
vehicle serviced.
Caution
Continuing to drive with worn-out
brake pads could result in costly
brake repair.
Some driving conditions or climatescan cause a brake squeal when thebrakes are first applied or lightlyapplied. This does not meansomething is wrong with the brakes.
Properly torqued wheel nuts arenecessary to help prevent brakepulsation. When tires are rotated,inspect brake pads for wear and
evenly tighten wheel nuts in theproper sequence to torquespecifications. SeeCapacities andSpecifications0304.
Brake pads should be replaced ascomplete sets.
Brake Pedal Travel
See your dealer if the brake pedaldoes not return to normal height,or if there is a rapid increase inpedal travel. This could be a signthat brake service may be required.
Replacing Brake System Parts
Always replace brake system partswith new, approved replacementparts. If this is not done, the brakesmay not work properly. The brakingperformance expected can changein many other ways if the wrongreplacement brake parts areinstalled or if parts are improperlyinstalled.

Brake Fluid
The brake/clutch master cylinderreservoir is filled with GM approvedDOT 3 brake fluid as indicated onthe reservoir cap. SeeEngineCompartment Overview0217forthe location of the reservoir.
Checking Brake Fluid
Place the vehicle in P (Park) orNeutral with the parking brakeapplied if equipped with a manualtransmission. On a level surface,the brake fluid level should bebetween the minimum andmaximum marks on the brake fluidreservoir.
There are only two reasons why thebrake fluid level in the reservoir maygo down:
.Normal brake lining wear. Whennew linings are installed, thefluid level goes back up.
.Afluidleakinthebrake/clutchhydraulic system. Have thebrake/clutch hydraulic systemfixed. With a leak, the brakes willnot work well.
Always clean the brake fluidreservoir cap and the area aroundthe cap before removing it.
Do not top off the brake/clutch fluid.Adding fluid does not correct a leak.If fluid is added when the linings areworn, there will be too much fluidwhen new brake linings areinstalled. Add or remove fluid, asnecessary, only when work is doneon the brake/clutch hydraulicsystem.
{Warning
If too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You
or others could be burned, and

Warning (Continued)
the vehicle could be damaged.
Add brake fluid only when work is
done on the brake/clutch
hydraulic system.
When the brake/clutch fluid falls to alow level, the brake warning lightcomes on. SeeBrake SystemWarning Light011 4.
Brake fluid absorbs water over timewhich degrades the effectiveness ofthe brake fluid. Replace brake fluidat the specified intervals to preventincreased stopping distance. SeeMaintenance Schedule0290.
What to Add
Use only GM approved DOT 3brake fluid from a clean, sealedcontainer. SeeRecommendedFluids and Lubricants0300.

234 Vehicle Care
{Warning
The wrong or contaminated brake
fluid could result in damage to the
brake system. This could result in
the loss of braking leading to a
possible injury. Always use the
proper GM approved brake fluid.
Caution
If brake fluid is spilled on the
vehicle's painted surfaces, the
paint finish can be damaged.
Immediately wash off any painted
surface.
