It could mean that your parking brake is engaged, that your brake fluid is low, or that there’s a problem with the ABS (Anti-lock Braking System). If the light remains on after disengaging the parking brake, have your braking system inspected immediately.
Tire Pressure Monitoring System (TPMS) Light
This symbol, resembling a horseshoe with an exclamation point, indicates that one or more of your tires have low tire pressure. Check the pressure in all your tires and inflate them to the recommended pressure specified in your owner’s manual or on the sticker located on the driver’s side doorjamb.
ABS (Anti-lock Braking System) Warning Light
This symbol, often the letters “ABS,” indicates a problem with your anti-lock braking system. While your regular brakes will still function, the ABS may not engage in an emergency situation. Have your ABS system inspected by a mechanic.
Traction Control System (TCS) Light
This symbol, often a car with squiggly lines behind it, indicates that the traction control system is active or that there’s a problem with the system. If the light is flashing, it means the TCS is actively working to prevent wheelspin. If the light is constantly on, it indicates a malfunction in the system.
Power Steering Warning Light
This symbol, often a steering wheel with an exclamation point, indicates a problem with your power steering system. You may notice that the steering wheel is harder to turn than usual. Have your power steering system inspected by a mechanic.
Airbag Warning Light
This symbol, often a person sitting with a seatbelt and a circle in front of them, indicates a problem with your airbag system. This is a serious safety issue, and you should have your airbag system inspected by a mechanic immediately.
Advanced Car Engine Symbols and Systems
Modern vehicles are equipped with increasingly sophisticated systems, leading to a wider array of engine symbols. Understanding these symbols can help you better diagnose and address potential issues.
Electronic Stability Program (ESP) Light
Similar to TCS, the ESP light indicates that the Electronic Stability Program is active or malfunctioning. ESP helps prevent skidding by selectively applying brakes to individual wheels. A constantly lit ESP light suggests a system malfunction requiring attention.
Diesel Particulate Filter (DPF) Light
This symbol, specific to diesel vehicles, indicates that the Diesel Particulate Filter is becoming clogged. The DPF traps soot and other particles from the exhaust. The light may illuminate to signal that a regeneration cycle is needed, which involves burning off the accumulated particles. Following the manufacturer’s recommendations for DPF maintenance is crucial.
AdBlue Warning Light
Also specific to diesel vehicles, the AdBlue warning light indicates that the AdBlue (Diesel Exhaust Fluid) level is low. AdBlue is used to reduce emissions. Refilling the AdBlue tank is essential to comply with emissions regulations.
Automatic Emergency Braking (AEB) Light
This symbol indicates that the Automatic Emergency Braking system is active or malfunctioning. AEB systems automatically apply the brakes in certain situations to prevent or mitigate collisions. A malfunction in this system requires prompt attention.
Lane Departure Warning (LDW) Light
This symbol indicates that the Lane Departure Warning system is active or malfunctioning. LDW systems alert the driver when the vehicle is drifting out of its lane. A malfunction in this system should be addressed to ensure optimal safety.
