What It Means: Also known as the Tyre Pressure Monitoring System (TPMS) symbol, this image signals an issue with your tyre pressure or the TPMS. If the TPMS symbol is solid, then the pressure in one or more of your tyres is too low or too high. If the TPMS symbol flashes for 60-90 seconds when you turn on your vehicle and then stays illuminated, even if your tyres are properly inflated, then something is wrong with your TPMS sensors. What To Do: Driving on low- or high-pressure tyres is unsafe and can cause damage to your tyres. We recommend stopping as soon as possible to inflate or deflate your tyres to the correct pressure. A malfunctioning TPMS will not affect your tyres’ performance, but it will keep the system from alerting you when your tyres are low.
