Fixing Brake System Warnings
The car light with an exclamation point is a brake system warning. Ignoring this light can lead to unsafe driving conditions. This guide will help you address common brake system issues.
Understanding and fixing these warnings can prevent accidents. Let’s explore some basic solutions you can try before visiting a mechanic.
Refilling Brake Fluid
Low brake fluid can trigger the warning light. Check your car’s manual for the brake fluid reservoir location. Make sure the fluid level is between the minimum and maximum marks.
If the fluid is low, refill it with the correct type. Always use the recommended brake fluid type for your car model.
Brake Pad Inspection And Replacement
Worn brake pads can also cause the warning light. Inspect the brake pads for wear. If they are thin or damaged, they need replacement.
Replacing brake pads is essential for safe braking. Consult your car’s manual or get help from a professional if needed.
When To See A Mechanic
If the warning light stays on after checking fluid and pads, see a mechanic. Persistent warnings might indicate more serious issues.
A professional can diagnose problems like brake line leaks or ABS issues. It is safer to let experts handle complex brake problems.
Resolving Tire Pressure Alerts
The car light with an exclamation point often signals a tire pressure problem. This alert helps keep you safe on the road. Low tire pressure can cause poor handling and wear on tires.
Fixing this issue is simple. You need to check your tire pressure, inflate tires properly, and reset the warning light.
How To Check Tire Pressure
Check your tire pressure when the tires are cold. Use a reliable tire pressure gauge for accuracy. Find the recommended pressure in your car manual or on the door frame.
Remove the valve cap and press the gauge onto the valve stem. Read the number on the gauge to see the current pressure.
- Check all four tires plus the spare, if you have one
- Compare the reading with the recommended pressure
- Note any tires that are underinflated
Inflating Tires Correctly
Use an air compressor to add air to low tires. Inflate tires to the recommended pressure only. Overinflation can be dangerous.
After inflating, check the pressure again with your gauge. Adjust the air if needed. Replace the valve caps securely.
- Do not inflate tires while they are hot
- Fill tires slowly to avoid overpressure
- Check tire pressure monthly for safety
Resetting The Tpms Light
The Tire Pressure Monitoring System (TPMS) light stays on until you reset it. Some cars reset automatically after driving. Others need a manual reset.
To reset manually, find the TPMS reset button. It is often under the steering wheel or in the glove box. Press and hold it until the light blinks off.
