Modern cars come equipped with an array of dashboard indicator lights designed to alert drivers to various conditions and issues within the vehicle. Understanding these lights can help ensure the proper functioning of your car and prevent potential breakdowns or accidents. This guide will explain common car dash indicator lights, their meanings, and the actions you should take when they illuminate.
Common Car Dash Indicator Lights
Check Engine Light
Appearance: An icon shaped like an engine or the word “CHECK.”
Meaning: This light indicates a problem with the engine or emission control system. The check engine light is one of the most common and often one of the most concerning indicator lights for drivers. It can signify many issues, from a loose gas cap to a serious engine malfunction.
Action: Have the vehicle inspected by a professional mechanic as soon as possible. Ignoring this light can lead to more significant problems and higher repair costs. Continuing to drive with the check engine light on can cause further damage to the engine or other components.
Battery Alert Light
Appearance: A battery icon or the word “BATT.”
Meaning: This light indicates a problem with the vehicle’s charging system. It could be due to a failing alternator, a dying battery, or other issues within the charging system. This light is essential as the vehicle relies on a properly functioning battery and charging system.
Action: Check the battery connections to ensure they are secure and corrosion-free. If the connections are fine, have the charging system tested by a mechanic. If the problem persists, consult a professional to avoid being stranded with a dead battery.
Oil Pressure Warning Light with Car Dash Indicator Lights
Appearance: An oil can icon.
Meaning: This light indicates low oil pressure, possibly due to a low oil level, a faulty oil pump, or other issues. Low oil pressure can lead to serious engine damage if not addressed promptly.
Action: Check the oil level immediately and top it up if necessary. If the light remains on after adding oil, seek immediate professional assistance. Driving with low oil pressure can cause severe damage to the engine.
Brake Warning Light
Appearance: An exclamation mark inside a circle or the word “BRAKE.”
Meaning: This light indicates an issue with the brake system, such as low brake fluid, a problem with the brake pads, or other issues. Brakes are critical for vehicle safety, so any warning related to the brake system should be taken seriously.
Action: Check the brake fluid level and add fluid if needed. If the light stays on after adding fluid, have the brake system inspected by a mechanic as soon as possible. Ignoring this light can lead to brake failure and pose a significant safety risk.
ABS Warning Light
Appearance: The letters “ABS.”
Meaning: This light indicates a problem with the Anti-lock Braking System (ABS). The ABS helps prevent the wheels from locking up during braking, especially in slippery conditions, ensuring better vehicle control.
Action: While the vehicle’s brakes will still work, they won’t benefit from ABS. Have the system checked by a professional to restore the full functionality of your braking system and ensure your safety.
Tire Pressure Monitoring System (TPMS) Light
Appearance: An exclamation mark inside a horseshoe shape.
Meaning: This light indicates that one or more tyres have low pressure. Proper tyre pressure is essential for safe driving, fuel efficiency, and prolonging the life of your tyres.
Action: Check the tyre pressures and inflate them to the recommended levels. If the light remains on, there could be a problem with the TPMS sensor. Consult a mechanic to diagnose and fix the issue.
Coolant Temperature Warning Light
Appearance: A thermometer inside a wave.
Meaning: This light indicates that the engine is overheating. Overheating can cause severe engine damage if not addressed quickly.
Action: Stop the vehicle immediately to avoid engine damage. Check the coolant level and add coolant if necessary. If the problem persists, seek professional assistance to identify and fix the underlying issue.
Airbag Warning Light
Appearance: A figure seated with a circle in front.
Meaning: This light indicates a problem with the airbag system. Airbags are a crucial safety feature designed to protect passengers in a collision.
Action: Have the airbag system inspected and repaired by a professional to ensure it functions correctly. Ignoring this warning can result in airbags failing to deploy during an accident, compromising safety.
Traction Control Light
Appearance: A car with squiggly lines behind it.
Meaning: This light indicates the traction control system is active or has a fault. The traction control system helps prevent wheel spin during acceleration on slippery surfaces.
Action: The system works if the light flashes while driving on a slippery surface. If it stays on, have the system checked by a professional to ensure it functions correctly, especially in adverse driving conditions.
Transmission Temperature Warning Light
Appearance: A thermometer inside a gear.
Meaning: This light indicates that the transmission is overheating. Overheating can cause significant damage to the transmission system.
Action: Stop the vehicle to allow the transmission to cool. Check the transmission fluid level and add fluid if necessary. If the problem continues, consult a mechanic to diagnose and fix the issue.
According to Forbes, nearly half of all cars on the road (49%) are being driven with one or more dashboard warnings.
Less Common Car Dash Indicator Lights
Low Fuel Warning Light
Appearance: A fuel pump icon.
Meaning: This light indicates that the fuel level is low. Running out of fuel can cause the engine to stop, potentially leading to dangerous situations.
Action: Refuel the vehicle as soon as possible to avoid running out of fuel and potentially damaging the pump.
Washer Fluid Warning Light
Appearance: A windshield with a wiper and water droplets.
Meaning: This light indicates that the washer fluid level is low. Washer fluid is essential for maintaining visibility by keeping the windshield clean.
Action: Refill the washer fluid reservoir to ensure you have enough fluid to clean the windshield when needed.
