Understanding Toyota Warning Lights

We’ve all seen our vehicles warning lights, but do we know what they mean? Or how important are they? Let’s take a minute to get a better understanding of  Toyota warning lights and what they mean.

All cars have a system to check that the warning lights are working properly. This happens when you first start your car, you’ll see all the warning lights illuminate and then dim moments later.  It is part of your car’s self-monitoring system. This is a good sign. In order for warning lights to be effective they must work. This lighting and dimming is doing just that. If one of the lights doesn’t illuminate, then the light is broken. If one, or more, of the lights stays lit when the others fad, then you are receiving a warning and should look into it. This isn’t the only time warning lights can come on. They will illuminate as soon as they sense an issue.

If one doesn’t, then you may want to bring the car in to Serra for servicing. Remember, we have a wonderful program called ToyotaCare– with the purchase or lease of every new Toyota for two years or 25,000 miles.

The second issue is if all the lights illuminate and then once the majority has dimmed some stay on. These are giving you a warning. Say your Check Engine Light comes on. Why not bring your vehicle by Serra for a free inspection?


How serious is it?

The first thing you should notice is the color of the light. Is it orange? This means – it’s a suggestion or a watch out for a potential problem. If the light is red, this means- attend to the problem immediately. If need be, pull over and call Serra so we can give you advice or better explain what the warning light means.

For example, the engine oil pressure might be on. This may not mean that you have to pull off the road immediately, but it does mean you should think about setting up an appointment to have your oil and filters changed. Oil is critical to your engine’s performance.

Part of proper maintenance and every day safety is knowing what each of the warning lights mean for your Toyota. We haven’t listed all the lights for all the models here, but the RV4 chart below should give a good starting point for better understanding of what the warning lights in your Toyota vehicle mean.

Remember to listen to them, they always have something important to say. We are always happy to take your calls or have you come by if you have questions. We also recommend regular maintenance as a great step towards keeping those lights from ever lighting up.
