Common Dashboard Warning Lights

Check Engine Light

One of the most recognized warning lights is the Check Engine Light. It can indicate a range of issues, from a loose gas cap to more serious engine problems. If this light comes on, it's advisable to have your vehicle checked by a professional mechanic as soon as possible.

Oil Pressure Warning

The Oil Pressure Warning light resembles an oil can. When illuminated, it suggests that the oil pressure in your engine is too low, which can lead to severe engine damage. Stop the vehicle immediately and check your oil levels or consult with a mechanic.

Safety-Related Warning Lights

Brake System Alert

The Brake System Alert light is usually a red exclamation mark within a circle. It may indicate a problem with the brake system or low brake fluid levels. Ignoring this light can compromise your vehicle’s braking efficiency, so immediate attention is needed.

Tire Pressure Monitoring

This light, which looks like an exclamation mark within a horseshoe, signals that one or more tires have low pressure. Driving with improperly inflated tires can lead to uneven tire wear and diminished fuel efficiency. Regularly check your tire pressure to ensure safety.
