For example, the light might come on if:
* Your oil pressure is low: This is a serious issue and requires immediate attention to prevent engine damage.
* Your engine temperature is high: This could indicate overheating, also a serious problem.
* Your battery voltage is low: This could indicate a charging system problem.
Do not ignore this light. Pull over safely as soon as possible and investigate. If you're unsure what the problem is, call a tow truck or roadside assistance. Continuing to drive with a "Check Gauges" light illuminated could cause significant damage to your vehicle.
