Check Engine Light

The Check Engine Light is one of the most common and misunderstood warning signals. This light can indicate a variety of issues ranging from a loose gas cap to a serious engine malfunction. If this light is steady, it’s wise to consult a mechanic soon. If it’s flashing, seek immediate attention as this indicates a severe issue.

Oil Pressure Warning

The Oil Pressure Warning light appears when there’s a drop in oil pressure, which could lead to engine damage. This could be due to low oil levels, a faulty oil pump, or a leaking oil filter. Check your oil level immediately and top it up if necessary. If the light persists, consult a professional.
