is cool.
If No Steam is Coming from
the Engine Compartment
The ENGINE OVERHEATED STOPENGINE or the ENGINEOVERHEATED IDLE ENGINEmessage, along with a low coolantcondition, can indicate a seriousproblem.
If there is an engine overheatwarning, but no steam is seen orheard, the problem may not be tooserious. Sometimes the engine canget a little too hot when the vehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.

If the ENGINE OVERHEATEDSTOP ENGINE or the ENGINEOVERHEATED IDLE ENGINEmessage appears with no sign ofsteam, try this for a minute or so:
1. Turn the air conditioning off.
2. Turn the heater on to thehighest temperature and to thehighest fan speed. Open thewindows as necessary.
3. When it is safe to do so, pull offthe road, shift to P (Park) orN(Neutral)andlettheengine idle.
If the temperature overheat gauge isno longer in the overheat zone or anoverheat warning no longer
displays, the vehicle can be driven.Continue to drive the vehicle slowlyfor about 10 minutes. Keep a safevehicle distance from the vehicle infront. If the warning does not comeback on, continue to drive normallyand have the cooling systemchecked for proper fill and function.

Adding Washer Fluid
The vehicle has a low washer fluidmessage on the DIC that comes onwhen the washer fluid is low. Themessage is displayed for15 seconds at the start of eachignition cycle. When the WASHERFLUID LOW ADD FLUID messagedisplays, washer fluid will need tobe added to the windshield washerfluid reservoir.
Open the cap with the washersymbol on it. Add washer fluid untilthe tank is full. SeeEngineCompartment Overview0354forreservoir location.
Caution
.Do not use washer fluid thatcontains any type of waterrepellent coating. This cancause the wiper blades tochatter or skip.
.Do not use engine coolant(antifreeze) in thewindshield washer. It candamage the windshieldwasher system and paint.
.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 if

freezing 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 beheard all the time the vehicle ismoving, except when applying thebrake 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 andevenly tighten wheel nuts in theproper sequence to torquespecifications inCapacities andSpecifications0468.
Brake linings should always bereplaced as complete axle 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 parts are improperlyinstalled.
Brake Fluid
The brake master cylinder reservoiris filled with DOT 3 brake fluid. SeeEngine Compartment Overview0354for the location of thereservoir.
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.
.Afluidleakinthebrakehydraulic system. Have thebrake hydraulic system fixed.With a leak, the brakes will notwork well.
Always clean the brake fluidreservoir cap and the area aroundthe cap before removing it.
Do not top off the brake 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 hydraulic system.
{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
the vehicle could be damaged.

378 Vehicle Care
Warning (Continued)
Add brake fluid only when work is
done on the brake hydraulic
system.
When the brake fluid falls to a lowlevel, the brake warning light comeson. SeeBrake System WarningLight0140.
Brake fluid absorbs water over time.Replace brake fluid at the specifiedintervals to prevent increasedstopping distance. SeeMaintenanceSchedule0452.
Checking Brake Fluid
Check brake fluid by looking at thebrake fluid reservoir. SeeEngineCompartment Overview0354.
The fluid level should be aboveMIN. If it is not, have the brakehydraulic system checked to see ifthere is a leak.
After work is done on the brakehydraulic system, make sure thelevel is above MIN but not over theMAX mark.
What to Add
Use only GM approved DOT 3brake fluid from a clean, sealedcontainer. SeeRecommendedFluids and Lubricants0462.
{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.
