Dashboard Lights are color-coded and display as steady or flashing based on urgency. Red indicates a warning, while yellow/orange indicates something of which you should be aware. Similarly, a flashing warning light often indicates a serious problem. A steady light is often a problem you need to address but one that won’t result in an immediate safety issue.

Check Engine Light

A flashing check engine light indicates urgent attention required. Your vehicle’s computer has detected a major malfunction. Don’t ignore, bring your vehicle to a Monro store to have our highly trained mechanics and technicians diagnose the issue. Our technicians use state-of-the-art equipment to perform a comprehensive review of your computer components, which aids in diagnosis.

A steady check engine light indicates your vehicle’s computer has detected a malfunction. Promptly bring your vehicle to a Monro store for diagnosis. In states requiring Safety/Emissions inspections, an illuminated check engine light may cause an inspection to fail.

Potential reasons for a check engine light:

  • Oxygen (o2) sensor malfunction: An o2 sensor measures the mixture of air in your exhaust fumes and tells the computer to adjust fuel usage based on these measurements. An o2 sensor malfunctioning can cause drivability issues because the computer doesn’t know what the correct air and fuel mixture should be.
  • Catalytic converter malfunction: This component is a part of your vehicle’s emissions system. The inside of a Catalytic Converter looks like a honeycomb filter that is designed to remove pollutants from your exhaust fumes. A Catalytic Converter can malfunction when these filters become clogged of contaminated.
  • Engine misfire: This happens when one of your motor cylinders isn’t producing power. Typically, a bad spark plug, faulty ignition coil, or a clogged fuel injector can cause these issues.
  • Gas cap issue: If a gas cap is loose or missing, a check engine light may come on when the Evaporative Emission Control System (EVAP) detects a potential leak of gas fumes into the air.

Brake Warning Light

A brake warning light requires immediate attention. A problem is detected within your brake system that can cause a failure to brake safely. Two important components to the brake system are brake fluid level and brake pad material level. These components work together to completely stop your vehicle. Bring your vehicle to a Monro store as soon as possible to have our highly trained mechanics diagnose and perform a comprehensive inspection of your brake system.

Make an appointment immediately if you are experiencing braking issues like:

  • Loss of brakes
  • Grinding or brake noise
  • Soft or spongy braking
  • Brake pulling, vehicle pulling to one side when braking
  • Pedal vibration

Antilock Brake System (ABS) Light

The Anti-lock Brake System (ABS) allows for additional control when extra traction is needed, often on slippery roads. The ABS light indicates the anti-lock function of the braking system has been disabled or is not functioning properly. A disabled ABS will cause your vehicle to have less traction control under maximum braking. The normal braking system still works. Bring your vehicle to a Monro store and have our technician diagnose and perform a comprehensive inspection of your brake system.

Oil Light

The oil light indicates the oil pressure has dropped very low or lost pressure. Running the vehicle with low or lost oil pressure can cause mechanical damage to the engine almost immediately. Bring your vehicle to the nearest Monro store as soon as possible to have our mechanics diagnose and repair the low oil pressure issue to get you back on the road.

Tire Pressure Monitoring System Light

The tire pressure monitoring system (TPMS) light can indicate there is a problem with your tires or the monitoring system. A flashing tire pressure warning light can mean that the TPMS sensor is malfunctioning and will no longer inform you if there is enough air in your tires. A steady TPMS light often indicates an over or under-inflated tire. Seasonal weather changes can cause fluctuation of air pressure readings in your tires. If you have added air and the light continues to stay on after a few trips, it may indicate a more serious issue. The cause could be a puncture, or a nail embedded in the tire, which requires repair. Driving on improperly inflated tires can cause unnecessary wear and tear on your vehicle. Bring your vehicle to a Monro store to have our mechanic diagnose and fix the issue, if needed, to get you safely and quickly back on the road.

Battery Charge Warning Light

The battery charge warning light indicates that the battery is not charging properly, or not holding a charge. The battery is responsible for starting the ignition system and powering other performance systems. It is important to have a good battery and functioning charging system to keep your vehicle moving. Schedule an appointment with your local Monro store today. Let our highly trained mechanics diagnose and perform a comprehensive inspection of your battery charging system.
