Vehicle dashboard warning lights are indicators on your car's dashboard designed to alert you about the status of your vehicle’s systems. These lights can indicate anything from a routine reminder (like low fuel) to serious mechanical or safety issues (like engine or brake failure). Here's a breakdown of the most common dashboard warning lights
Which is the best variant of the Jeep Wrangler?
Yellow triangle with an exclamation point
This leading warning light lets you know that an alert error has been logged and will be illuminated until you acknowledge that you have seen it. It logs every alert and stores them in the vehicle's ECU.
Petrol pump
This alert lets you know that you are running low on fuel or the vehicle's fuel delivery system is malfunctioning.
Crossed-out person
This alert lets you know the driver or passengers have not buckled their seatbelts. It may come as a single indicator, or the vehicle may have a layout that shows which seatbelt is unbuckled.
Floating key
This floating key indicates a thermometer and alerts you if the vehicle's coolant level is too hot. Some vehicles will have colour-changing versions indicating if the coolant is below freezing. This often warns you that the car is overheating or the cooling system is malfunctioning.
Wheel-spinning car
If the traction control system is deactivated or actively functioning, this alert will go off. It prevents the car from losing traction or allows the driver to break traction actively.
4WD
This warning light indicates that the low-range or 4x4 system is active, enabling the vehicle to tackle harsh terrain.
Wheels with lines joining them
This warning light indicates that the rear wheels and diff have been locked so the vehicle can better negotiate the terrain.
Wheels with lines joining them, with a dot at the centre
This warning light indicates that the entire 4x4 system is locked up and will significantly improve the vehicle's off-road prowess (for extreme use cases)
ABS circle
This alert will go off if the anti-lock braking system malfunctions or flashes rapidly, indicating that it actively prevents the brakes from locking up under heavy braking.
Circle with an exclamation point or P
This alert will illuminate if the handbrake is activated or if there is a problem with the brakes. If you release the handbrake, electrical or manual, this alert should disappear. If it does not, there is a problem with the braking system, and you should not drive the car at all.
Battery
This warning light will come on if there is a problem with the car's battery or if there is a problem with the car's charging system.
Engine
This warning light will illuminate if there is a problem with the car's sensor array that controls the engine (ECU). If it stays illuminated, the sensor malfunctions, and the engine will not run properly.
Oil Can
Sadly, it is too late if this warning light comes on and stays on. It means the engine's oil level is below operating levels, and you are running low on oil. You risk serious engine damage if you continue operating without checking and refilling oil.
U-shape with an exclamation point
This warning light points toward the TPMS, or Tyre Pressure Monitoring System. This alert will come if one or more of your car's tyres run below the operating pressure. It could indicate a puncture or an underinflated wheel.
