With most of us having roadside assistance either through our manufacturer’s warranty or through our auto insurance, if you see a flat, call for help and get it fixed before you move your vehicle. Since you won’t know the cause when you see the indicator, the first thing you should do is take a few seconds, walk around your vehicle, and make sure you aren’t driving on a flat. If a sensor is broken, it will read the pressure as “zero” and trigger the warning light. Each tire has a pressure sensor in the valve stem that sends a signal to the “brain” of the system. Many of these can be repaired, saving you the cost of a tire replacement.Īdditionally, if you have recently purchased tires (especially if you did not get them from the dealership), it is possible that one of the sensors was broken during the tire mounting process. It is worth while to have the tire checked out if you see this light. Other factors can cause a tire to become improperly inflated, including punctures from nails, screws and other debris. This will often trigger the light you see above. When it gets colder, the air pressure in our tires will drop. Living in Minnesota, with the changes in climate that we experience, this symbol has a tendency to show itself frequently during the Spring and the Fall seasons, when temperatures vary greatly from day to day. They can be a nuisance, but they are there for the protection of the consumer. In all reality, what it is saying is “Check your tires!” Since a certain SUV had issues with tires a number of years ago, the US Government issued a mandate that any vehicle built from 2007 forward would have an acceptable Tire Pressure Monitoring System. I have had many customers call, trying to describe it to me, and to ask what the heck it is, and what it is trying to tell them. If your vehicle is a 2007 or newer (and a few older models as well), there is a good chance you have seen this symbol at some point during your ownership.
