BMW X3 Dashboard Warning Lights

Decoding BMW X3 warning lights

The BMW X3 has become one of the Bavarian brand's best-selling models in recent years as consumers continue to drift away from sedans and into mid-size SUVs. BMW South Africa can cry king now, as the BMW X3 is built locally in Rosslyn and is a world-class product worthy of the praise it's received.

Early 2025 saw the introduction of the 4th generation model to SA, with the new model sporting a giant digital dashboard, infotainment screen, and new driver assistance systems. The tech may be new, and the screens may be eye-catching, but the warning lights that BMW uses to relay information to the driver haven't changed. Below, we have collected the most common warning lights you may possibly see while driving, and if you aren't sure what they mean, we can help with this handy guide.

The All-New, Proudly South African, BMW X3

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 cars 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.

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 severe 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. 

A vehicle with a wrench

This warning light will come on when your vehicle is due for its on-time service, usually at the service intervals listed in the owner's manual. Failure to take the vehicle for service may cause it to drop into limp mode until it is serviced and reset by a technician.
