Dashboard Warning Lights.

There are many different vehicle dashboard warning lights that come on throughout the lifetime of your vehicle. Some, like your fuel light, are fairly common and can cause you to become accustomed to seeing a light appear on your dashboard. However, some less obvious and infrequently seen dashboard warning lights are serious and require immediate attention.

Dashboard Warning Lights – What do they mean?

Vehicle dashboard warning lights can be easily ignored, especially if your car has a large variety of messages and lights that appear randomly triggered. However, it’s important that you can identify these 5 vehicle dashboard warning lights because they can be serious.

When in doubt about what your vehicle light really means, your first reference point should be your vehicles manual but at Reliance Bicester, our trained technicians normally recommend you seek an additional opinion from one of our team. A professional investigation with the latest diagnostic equipment will definitely give you peace of mind and identify any serious issues.

Check Engine Light

Your check engine light, although it could mean a multitude of things, is also a dashboard warning light you shouldn’t ignore. If this light comes on you should bring to Reliance Bicester or a local garage for further diagnosis. The top things a check engine warning light means is usually either a faulty oxygen sensor, a loose fuel cap, a catalytic converter that needs replacing or faulty spark plugs or plug wires.

Brake Light

If the brake light comes on, this could mean one of three things. First, it could mean that your emergency brake is still on as you’re trying to drive. Make sure that it is in the off position before moving forward. It could also mean that your brake pads have worn down exposing the brake sensors that tell you it’s time to change your brakes. You should get your brakes checked immediately if that’s the case. A third reason this dashboard light may be on is if there is a problem with your automatic braking system (ABS). If this is the case it will require further diagnostic testing.

Airbag Warning Light

An airbag is a crucial part to keeping you safe in your car. If your airbag warning light comes on, it isn’t something you should ignore. This dashboard warning light means that a fault has been found in an airbag located in the vehicle. It’s highly recommended that your airbags and the system in place to get them to work be checked out to ensure that everything is working properly.

Oil Pressure Warning Light

Another vehicle dashboard warning light you shouldn’t ignore is your oil pressure warning light. If this light turns on it means that your oil pressure or oil levels are low. You should pull over and turn off your car immediately to check oil levels, if you have concerns then please bring it to Reliance Bicester or take it to a local garage to assess the issue further. Running your car on low oil could cause it to abruptly stop and could damage your engine. Resulting in larger repair costs, so don’t delay.

Coolant Temperature Warning Light

A coolant temperature warning light is also a dashboard warning light you shouldn’t ignore. This means that your vehicles temperature has reached an unsafe level. If this is the case you should turn your car off to let it cool down. Then you should check your coolant levels again or look to see if coolant is leaking. You should also have your radiator cap or fan checked to make sure it is not malfunctioning.

Preventive Maintenance

Additionally, regular routine servicing and maintenance is crucial for increasing your vehicles longevity and maximising its performance. Not only does it work to rectify any current wear and tear in your vehicle, but it also effectively aids in preventing further damage from presenting itself in the future.
