All Those Dash Warning Lights! What Do they Mean?

On most new cars, when you turn on the key, there are an overwhelming number of dash warning lights that come ON while doing their self-test, then they go off when the engine is started. But what happens when one comes ON while I am driving? Is it a serious problem?  Should I shut off the car and stop driving and call Stouch’s? Or can I continue to drive for the rest of the day, and then call Stouch’s to find out why the light came ON? 

If the Light is RED, stop and shut off the engine!

  • This is usually associated with:
    • The Red Brake Warning Light
    • The Red Engine Temperature Light
    • The Red Oil Pressure Light
  •  Further Driving when any of these light is ON, may damage the engine OR cause a safety problem.

If the Light is ORANGE or YELLOW, it is usually a warning or caution for something you can keep driving with, but should have checked

  • This includes, but is not limited to:
    • Air Bag or SRS (Supplemental Restraint System)
      • When this light is ON, the Air Bag system will not perform in the event of an accident.
      • It is also important to note, the air bags will not accidentally deploy or go off.
      • We recommend having this important safety item  checked and repairs.
    • ABS (Anti-Lock Brake System)
      • When this light comes ON, your normal brakes will operate fine – no problem.
      • But, the ABS system will not work.
      • ABS was added to the car to help you keep control of the car during hard braking, particularly in wet/slippery weather.
      • We recommend having this important safety system checked and repairs.
    • Check Engine! Service Engine Soon! Or an Engine Symbol or graphic on the dash!
      • Yes, we know, the engine is still there!  Some people have been known to open the hood just to check for it!
      • When this light comes on, the car computer is indicating it has found a fault somewhere in its system.
        • Usually it is a problem that is affecting the vehicle emissions.
        • Sometimes, it is also a problem that will cause the engine to stop running, not start, or suffer other driveability problems.
      • There are hundreds of faults that can cause this light to come ON.
      • We recommend calling us to determine what the fault is and what it would take to repair it.
    • TPMS (Tire Pressure Monitoring System)
      • This indicates either: one of the tires is low in air; or there is a fault in the tire pressure monitoring system.
      • At minimum, we recommend checking tire pressure.  If the light remains, we may need to evaluate the cause for repair.
