Compartment
If an engine overheat warning is displayed but no steam can be seen or heard, the problem may not be too serious. Sometimes the engine can get 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 overheat warning is displayed with no sign of steam:
- Turn the air conditioning off.
- Turn the heater on to the highest temperature and to the highest fan speed. Open the windows as necessary.
- When it is safe to do so, pull off the road, shift to P (Park) or N (Neutral), and let the engine idle. If the engine coolant temperature gauge is no longer in the overheated area, the vehicle can be driven. Continue to drive the vehicle slowly for about 10 minutes. Keep a safe distance from the vehicle in front. If the warning does not come back on, continue to drive normally and have the cooling system checked for proper fill and function. If the warning continues, pull over, stop, and park the vehicle right away. If there is no sign of steam, idle the engine for three minutes while parked. If the warning is still displayed, turn off the engine until it cools down.

Washer Fluid
What to Use
When windshield washer fluid is needed, be sure to read the manufacturer’s instructions before use. If operating the vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing.
Adding Washer Fluid
Open the cap with the washer symbol on it. Add washer fluid until the tank is full. See Engine Compartment Overview 0 250 for reservoir location.
Caution
- Do not use a washer fluid that contains any type of water-repellent coating. This can cause the wiper blades to chatter or skip.
- Do not use engine coolant (antifreeze)in the windshield washer. It can damage the windshield washer system and paint.
- Do not mix water with ready-to-use washer fluid. Water can cause the solution to freeze and damage the washer fluid tank and other parts of the washer system.
- When using concentrated washer fluid, follow the manufacturer’s instructions for adding water.
- Fill the washer fluid tank only three-quarters full when it is very cold. This allows for fluid expansion if freezing occurs, which could damage the tank if it is completely full.
Brakes ( Chevrolet owner’s manual )
Disc brake linings have built-in wear indicators that make a high-pitched warning sound when the brake linings are worn and new linings are needed. The sound can come and go or can be heard all the time when the vehicle is moving, except when applying the brake pedal firmly.
Warning
The brake wear warning sound means that soon the brakes will not work well. That could lead to a crash. When the brake wear warning sound is heard, have the vehicle serviced.
Caution
Continuing to drive with worn-out brake linings could result in costly brake repairs. Some driving conditions or climates can cause a brake squeal when the brakes are first applied, clearing up following several applications.
This does not mean something is wrong with the brakes. Properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake linings for wear and evenly tighten wheel nuts in the proper sequence to torque specifications. See
Capacities and Specifications 0 326. Brake pads should be replaced as complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign that brake service may be required. Replacing Brake System Parts Always replace brake system parts with new, approved replacement parts. If this is not done, the brakes may not work properly. The braking performance can hinge in many ways if the wrong brake parts are installed or if the parts are improperly installed.
