Your Nissan's dashboard communicates with you through its lights and symbols. When those icons light up, your car is trying to tell you something important. It may be just a friendly reminder about upcoming maintenance, or it could signal an urgent issue that requires immediate attention. In this Nissan dashboard warning light guide, our team at Parkway Nissan provides everything you need to know about each symbol, how quickly you need to act, and how to keep your car in optimal condition on Dover's roads.

Your Nissan car light symbols are not all the same. Nissan uses colors to indicate the severity of an issue. Warning lights indicate issues or malfunctions that need immediate attention, typically appearing in yellow or red. They highlight problems that can impact your car's performance, safety, or reliability. The check engine light usually appears in amber. When this light stays illuminated, it indicates a serious issue that requires attention soon.

Indicator lights serve a different purpose. They simply keep you updated on your car's operations. These lights are typically blue or green and show which systems are active and running smoothly. Examples include your turn signal, the high-beam symbol, or the cruise control light. Blue and green lights are purely informational and don't need any action on your part.

Some dashboard lights demand immediate attention. The oil pressure warning, denoted by an oil can symbol, indicates your engine is not receiving sufficient oil flow. You should pull over immediately, shut off the engine, and check the oil levels. If you ignore this, you may be looking at engine replacement costs of $4,000 to $8,000.

The thermometer symbol indicates that your engine is overheating, and you have only minutes before serious damage occurs. Find a safe place to stop and allow your car to cool completely. Ignoring this light can lead to repairs for a blown head gasket, which can cost between $2,500 and $6,000.

If the brake warning light comes on, it means your stopping power is compromised, while a battery light indicates a failing charging system. If your check engine light is flashing instead of staying steady, it signals a serious problem. A misfiring engine can damage emissions systems and potentially cause fires, while timing issues can lead to complete engine failure.

Current Nissan models come with various advanced safety technologies, each featuring its own warning light. The airbag symbol indicates that your airbag system may not function properly in a crash, requiring immediate attention. The ABS light indicates a problem with the antilock braking system, which prevents your wheels from locking during emergency stops. If you see the stability control light, you should check the systems that prevent skidding and help you stay in control on slippery roads.

Although illuminated tire pressure lights are common in Dover's cold weather, you should check them anyway. Improper tire pressure can lead to blowouts or suspension damage, which can cost between $500 and $1,000 to repair. Automatic emergency braking warning lights indicated that the sensors may not be working correctly, meaning your car may not detect and react to potential collisions as effectively as it should.

Transmission warnings typically indicate problems such as overheating, low fluid pressure, or mechanical issues causing poor shifts and strange noises. These problems can seriously affect your budget, as they often require replacing catalytic converters, oxygen sensors, ignition coils, and spark plugs. You shouldn't ignore these warning lights, since issues can lead to increased wear and higher fuel costs.

Driver-assistance features are crucial for keeping you safe on the road. ProPILOT Assist warnings signal that the system managing speed, steering, and braking needs attention. Intelligent cruise warnings mean the adaptive systems aren't maintaining safe distances. Blind-spot warning lights indicate sensor issues, while illuminated rear cross-traffic alert symbols denote backup detection problems.

While they may not signal urgent issues, comfort and convenience lights play a significant role in your driving experience. A power steering warning means your steering assist isn't working correctly, while electronic parking brake lights signal automatic braking issues, though you can manually override most systems if necessary.

The suspension warning light indicates issues that can affect comfort and stability, which can cause uneven tire wear. The snowflake icon alerts you that conditions are right for icy roads, which is especially helpful during Dover winters when roads are slippery. Don't ignore the washer fluid light. Driving in a winter storm when the roads are coated with salt can quickly turn your windshield into a blurry mess.

Always pay attention when the warning lights on your dashboard come on. Ignoring these warnings can cause bigger problems and lead to expensive repairs.
