Dashboard Warning Lights: Before, During, and After Driving

Common dashboard warning lights and their causes

Listed below are explanations of the common dashboard warning lights and the causes associated with them.

Check Engine Light

The check engine light is one of the most commonly encountered dashboard warning signs. It indicates a problem with the vehicle's engine or emission control system.

 

Possible causes: Issues can range from a loose gas cap to a malfunctioning oxygen sensor, to more serious problems like engine misfire or catalytic converter issues.

 

Oil Pressure Warning

The oil pressure warning light indicates that the engine oil pressure has dropped below a critical level.

 

Possible causes: Low oil level, a failing oil pump, or an oil leak could trigger this warning.

 

Battery Light

The battery light usually indicates a problem with the charging system, signalling that the vehicle is running on battery power alone.

 

Possible causes: A faulty alternator, loose or corroded battery connections, or a broken drive belt could be the underlying issues.

 

Brake System Warning

The brake system warning light can illuminate for various reasons, such as low brake fluid level, worn brake pads, or a malfunction in the anti-lock braking system (ABS).

 

Possible causes: Low brake fluid, worn brake pads, or ABS sensor malfunctions are common reasons for this warning.

 

Tire Pressure Monitoring System (TPMS) Light

The TPMS light signifies that one or more of the tires are under-inflated, potentially compromising vehicle safety and fuel efficiency.

 

Possible causes: Under-inflated tires due to a puncture, seasonal temperature changes, or a malfunctioning TPMS sensor can trigger this warning.

 

Airbag Warning

The airbag warning light indicates a problem with the vehicle's supplemental restraint system (SRS) and may compromise the functionality of the airbags in the event of a collision.

 

Possible causes: Faulty crash sensors, damaged wiring, or issues with the airbag control module could be potential causes of this warning.

 

Coolant Temperature Warning

The coolant temperature warning light signals that the engine is overheating, which can lead to severe damage if not addressed promptly.

 

Possible causes: Low coolant level, a malfunctioning thermostat, or a faulty cooling fan could trigger this warning.

 

ABS Light

The ABS light indicates a problem with the anti-lock braking system, which is designed to prevent the wheels from locking up during braking, especially in slippery conditions.

 

Possible causes: Faulty ABS sensors, damaged wiring, or issues with the ABS hydraulic unit could be potential causes of this warning.

 

What to Check Before Driving

Engine Oil Level

1. Importance of Checking Oil Level

Before embarking on a journey, it's crucial to ensure that the engine has sufficient oil. This lubricates the engine components, reducing friction and heat generation.

 

2. How to Check the Oil Level

Locate the engine oil dipstick, remove it, and wipe it clean. Reinsert the dipstick fully, then remove it again to observe the oil level.

 

3. Consequences of Low Oil Level

Insufficient oil can lead to engine damage, reduced performance, and potential breakdowns, emphasising the importance of maintaining appropriate oil levels.

 

Tire Pressure

1. Importance of Proper Tire Pressure

Correct tire pressure ensures optimal traction, stability, and fuel efficiency. It also extends the lifespan of the tires.

 

2. Methods for Checking Tire Pressure

Utilise a tire pressure gauge to measure the pressure in each tire, ensuring it matches the recommended levels in the owner's manual.

 

3. Impacts of Incorrect Tire Pressure

Underinflated tires increase the risk of blowouts while overinflated tires compromise handling, emphasising the need for proper tire pressure maintenance.

 

Coolant Level

1. Importance of Proper Coolant Level

Adequate coolant prevents the engine from overheating, especially crucial for long trips and hot weather conditions.

 

2. How to Check the Coolant Level

Locate the coolant and check that the fluid level falls between the minimum and maximum marks.

 

3. Potential Consequences of Low Coolant Level

Insufficient coolant can lead to engine overheating, which may cause extensive damage and potential safety hazards, underlining the necessity of maintaining proper coolant levels.

 

What to check while driving

Engine Temperature

1. Understanding the Engine Temperature Gauge

Monitor the engine's temperature gauge, ensuring it remains within the normal operating range. Increases or fluctuations could indicate overheating.

 

2. Signs of Overheating and Precautions to Take

If the engine temperature rises, turn off the air conditioning, activate the heater, and pull over to a safe location to allow the engine to cool down.

 

3. Importance of Addressing Overheating Promptly

Ignoring an overheating engine can lead to severe damage, such as a blown head gasket, which is costly to repair and may require the engine to be replaced.

 

Oil Pressure

1. Interpreting the Oil Pressure Warning

If the oil pressure light illuminates, it indicates low oil pressure, which can lead to engine damage if not addressed promptly.

 

2. Actions to Take if the Oil Pressure Light Comes On

Pull over and turn off the engine immediately to prevent further damage, then check the oil level and contact a professional if needed.

 

3. Potential Consequences of Ignoring Oil Pressure Issues

Persistent low oil pressure can result in engine wear, reduced performance, and, in the worst-case scenario, complete engine failure.

 

Brake System

1. Recognising Brake Warning Lights

Be familiar with the brake system warning lights and their significance, such as ABS, brake fluid, or brake pad wear indicators.

 

2. Safety Precautions if the Brake System Warning Light Activates

If a brake warning light illuminates, reduce speed and assess the braking performance. Avoid sudden or hard braking and seek immediate professional attention.

 

3. Importance of Addressing Brake System Issues Immediately

The brake system is critical to vehicle safety, and any issues should be addressed promptly to avoid potential accidents or further damage to the braking components.

 

What to Check After Driving

Fluid Leaks

1. Identifying Potential Fluid Leaks

After parking, inspect the ground beneath the vehicle for any signs of fluid leaks, including oil, coolant, transmission fluid, or brake fluid.

 

2. Actions to Take if Leaks Are Detected

Address any identified leaks promptly by determining their source and seeking professional assistance to prevent further damage or safety hazards.

 

3. Consequences of Ignoring Fluid Leaks

Neglecting fluid leaks can lead to low fluid levels, component damage, or system failures, posing potential safety risks and expensive repairs.

 

Dashboard Indicator Reset

1. Understanding the Need for Resetting Warning Indicators

After resolving any issues indicated by dashboard warning lights, it's necessary to reset the relevant indicators to ensure accurate future notifications.

 

2. How to Reset Dashboard Warning Lights

Refer to the vehicle's owner's manual for specific instructions on resetting dashboard warning lights, as the process can vary depending on the make and model.

 

3. Ensuring Readiness for the Next Drive

By resetting dashboard warning lights after addressing any issues, drivers can ensure that the vehicle's monitoring systems are prepared for the next journey.

 

Sounds and Smells

1. Noticing Unusual Sounds or Smells After Driving

Pay attention to any unusual sounds, such as grinding, squealing, or knocking, as well as unusual smells like burning, fuel, or exhaust odours.

 

2. Identifying Potential Issues Based on Sounds and Smells

Unusual sounds or smells can indicate underlying problems with various vehicle components, signalling the need for further inspection and potential maintenance.

 

3. Seeking Professional Assistance for Post-Driving Concerns

If any concerning sounds or smells are present after driving, it's essential to seek professional assistance to diagnose and address any emerging issues effectively.
