Chevrolet Blazer 2023 Brake Fluid User Guide
The brake master cylinder reservoir is filled with GM-approved DOT 4 brake fluid as indicated on the reservoir cap. See Engine Compartment Overview 0 250 for the location of the reservoir.
Checking Brake Fluid
With the vehicle in P (Park) on a level surface, the brake fluid level should be between the minimum and maximum marks on the brake fluid reservoir.
There are only two reasons why the brake fluid level in the reservoir may go down:
- Normal brake lining wear. When new linings are installed, the fluid level goes back up.
- A fluid leak in the brake hydraulic system.
Have the brake hydraulic system fixed. With a leak, the brakes will not work well.
Always clean the brake fluid reservoir cap and the area around the 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 are worn, there will be too much fluid when new brake linings are installed. Add or remove fluid, as necessary, only when work is done on the brake hydraulic system.
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. Add brake fluid only when work is done on the brake hydraulic system.
When the brake fluid falls to a low level, the brake warning light comes on. See Brake System Warning Light 0 102. Brake fluid absorbs water over time which degrades the effectiveness of the brake fluid. Replace brake fluid at the specified intervals to prevent increased stopping distance. See Maintenance Schedule 0 317.
What to Add
Use only GM-approved DOT 4 brake fluid from a clean, sealed container. See Recommended Fluids and Lubricants 0 321.
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.
If the brake fluid is spilled on the vehicle’s painted surfaces, the paint finish can be damaged. Immediately wash off any painted surface.
Battery – North America
The original equipment battery is maintenance-free. Do not remove the cap and do not add fluid. Refer to the replacement number on the original battery label when a new battery is needed. For replacement of the battery, see your dealer.
The vehicle has a Stop/Start system to shut off the engine to help conserve fuel. See Stop/Start System 0 194. It has an Absorbed Glass Mat (AGM) 12-volt battery. Installation of a standard 12-volt battery will result in reduced 12-volt battery life. When using a 12-volt battery charger on the 12-volt AGM battery, some chargers have an AGM battery setting on the charger. If available, use the AGM setting on the charger, to limit charge voltage to 14.8 volts.
Battery posts, terminals and related accessories can expose you to chemicals including lead and lead compounds, which are known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling. For more information go to www.P65Warnings.ca.gov
See the warning on the back cover.
Batteries have acid that can burn you and gas that can explode. You can be badly hurt if you are not careful. See Jump Starting – North America 0 301 for tips on working around a battery without getting hurt.
Infrequent Usage: Remove the black, negative (−) cable from the battery to keep the battery from running down.
Extended Storage: Remove the black, negative (−) cable from the battery or use a battery trickle charger.
All-Wheel Drive Transfer Case
Under normal driving conditions, transfer case fluid does not require maintenance unless there is a fluid leak or unusual noise. If required, have the transfer case serviced by your dealer.
Park Brake and P (Park) Mechanism Check
When you are doing this check, the vehicle could begin to move. You or others could be injured and property could be damaged. Make sure there is room in front of the vehicle in case it begins to roll. Be ready to apply the regular brake at once should the vehicle begin to move.
Park on a fairly steep hill, with the vehicle facing downhill. Keeping your foot on the regular brake, set the parking brake.
- To check the parking brake’s holding ability: With the engine running and the transmission in N (Neutral), slowly remove foot pressure from the regular brake pedal. Do this until the vehicle is held by the parking brake only.
- To check the P (Park) mechanism’s holding ability: With the engine running, shift to P (Park). Then release the parking brake followed by the regular brake.
Contact your dealer if service is required.
Windshield wiper blades should be replaced periodically. See Maintenance Schedule 0 317.
Replacement blades come in different types and are removed in different ways. For proper type and length, see Maintenance Replacement Parts 0 322.
Allowing the wiper arm to touch the windshield when no wiper blade is installed could damage the windshield. Any damage that occurs would not be covered by the vehicle warranty. Do not allow the wiper arm to touch the windshield.
Front Wiper Blade Replacement
To replace the wiper blade:
- Pull the wiper assembly away from the windshield.
- Lift up on the latch in the middle of the wiper blade where the wiper arm attaches.
With the latch open, pull the wiper blade down toward the windshield far enough to release it from the J-hooked end of the wiper arm.
- Remove the wiper blade.
- Reverse Steps 1–3 for wiper blade replacement.
Rear Wiper Blade Replacement
The rear wiper blade and wiper arm have a cover for protection.
To remove the cover:
- Slide a plastic tool under the cover and push upward to unsnap.
- Slide the cover toward the wiper blade tip to unhook it from the blade assembly.
- Remove the cover.
- After the wiper blade replacement, ensure that the cover hook slides into the slot in the blade assembly.
- Snap the cover down to secure it.
To replace the wiper blade:
- Lift the wiper arm away from the windshield.
