Your dashboard is your car’s way of communicating with you. Whether it’s the check engine light, low tire pressure warning, or a drivetrain malfunction alert, these lights shouldn’t be ignored. At Duxler Libertyville Tire, we help local drivers understand what these dashboard warning lights mean and how to handle them before they turn into bigger issues.

Understanding Your Dashboard Warning Lights

Modern vehicles are equipped with dozens of sensors that monitor performance and safety. When something’s off, your dashboard alerts you. Here are the most common warning lights we see in our Libertyville shop:

Check Engine Light

The check engine light is one of the most important—and commonly misunderstood—warnings. It can indicate anything from a loose gas cap to a serious engine problem.

• Solid light: Schedule diagnostics soon
• Flashing light: Pull over immediately—this could mean engine misfires or major system failure
  
  

Low Tire Pressure Warning (TPMS Light)

This horseshoe-shaped icon with an exclamation mark means one or more of your tires are underinflated. Driving with low tire pressure reduces fuel efficiency and increases your risk of a blowout.

We offer free tire pressure checks and TPMS resets at Duxler Libertyville Tire.

Drivetrain Malfunction Warning

If your vehicle displays a drivetrain malfunction alert—common in newer models like BMWs or Audis—it could point to engine or transmission issues. You may experience reduced power or “limp mode.” This should be diagnosed as soon as possible to avoid serious damage.

Battery Warning Light

This light signals a problem with your car’s charging system. It might be a failing alternator or weak battery. If this light comes on while driving, your vehicle may soon lose electrical power.

Brake System Warning

This could mean anything from low brake fluid to worn-out pads or ABS issues. If you hear grinding or squealing, schedule a brake inspection immediately.

Why Dashboard Warning Lights Matter

Ignoring dashboard lights can lead to:

• Unsafe driving conditions
• Higher repair costs down the line
• Potential breakdowns or failures
• Reduced fuel efficiency and performance
