Engine Warning Light (Check Engine Light)
The Engine Warning Light, often referred to as the Check Engine Light, is one of the most critical dashboard indicators.
When this light comes on, it means that the engine control unit has detected an issue with the engine or its components.
This light can be triggered by a variety of issues, ranging from minor to severe.
Common causes include faulty oxygen sensors, which measure the amount of unburned oxygen in the exhaust, loose gas caps, which can cause fuel vapors to leak and trigger the light, malfunctioning catalytic converters, which help reduce exhaust emissions, and problems with the spark plugs and wires, which are essential for the ignition process.
If this light is steady, you should schedule a service appointment as soon as possible to diagnose the issue.
However, if the light is flashing, it indicates a severe issue such as a misfire, which can cause significant damage to the engine and catalytic converter if not addressed immediately.

Battery Charge Warning Light
The Battery Charge Warning Light indicates a problem with the vehicle’s charging system, which can include issues with the alternator, voltage regulator, or the battery itself.
This light typically appears as a battery icon and signifies that the battery is not being charged correctly.
If this light comes on while driving, it is essential to try to minimize electrical usage by turning off non-essential electrical components such as the radio, air conditioning, and headlights if possible.
Head to a service center immediately to have the charging system inspected.
Continuing to drive with this light on can lead to the battery depleting completely, which may cause the vehicle to stop running.
Oil Pressure Warning Light
The Oil Pressure Warning Light signals a drop in the oil pressure, which can lead to severe engine damage if not addressed promptly.
This light often appears as an oil can icon and can be triggered by low oil levels, oil leaks, or a faulty oil pump.
When this light illuminates, it is crucial to pull over safely and check the oil level using the dipstick.
If the oil level is low, add oil to bring it to the proper level.
If the light remains on after adding oil, it is advisable not to drive the vehicle and to seek professional assistance immediately, as driving with low oil pressure can cause extensive engine damage.
Brake System Warning Light
The Brake System Warning Light can indicate several potential issues within the brake system.
This light may come on due to low brake fluid, problems with the ABS system, or worn brake pads.
When this light appears, it is vital to check the brake fluid level in the reservoir under the hood.
If the fluid is low, top it up with the recommended type of brake fluid for your vehicle.
If the light persists after adding fluid, there could be a more severe issue with the brake system, such as a leak or worn brake pads, which require immediate inspection by a professional mechanic.
Driving with compromised brakes can be extremely dangerous.
Tire Pressure Monitoring System (TPMS) Light
The TPMS Light warns of low tire pressure, which can affect vehicle handling, fuel efficiency, and tire longevity.
This light usually appears as an exclamation mark inside a horseshoe-shaped icon.
Low tire pressure can be caused by a puncture, seasonal temperature changes, or gradual loss of air over time.
It is essential to check the tire pressures using a tire pressure gauge and inflate them to the recommended levels found in your vehicle’s owner’s manual or on the driver’s side door jamb.
If the light remains on after inflating the tires, there might be a puncture or an issue with the TPMS sensors that require professional attention.
ABS Warning Light
The ABS Warning Light indicates a problem with the Anti-lock Braking System (ABS), which prevents the wheels from locking up during hard braking.
This light often appears as the letters “ABS” within a circle. Common causes for this light include faulty ABS sensors, damaged wiring, or issues with the ABS module.
While the vehicle can still be driven with this light on, the ABS system will not function properly, increasing the risk of wheel lock-up during hard braking.
It is essential to schedule a service appointment to have the ABS system checked and repaired to ensure optimal braking performance and safety.
Airbag Warning Light
The Airbag Warning Light signals an issue with the vehicle’s airbag system, which is critical for occupant safety in the event of a collision.
This light typically appears as a person seated with an airbag deploying in front of them.
Common causes for this light include faulty airbag sensors, damaged wiring, or issues with the airbag control unit.
Since this can affect the safety of the vehicle occupants in the event of a collision, it is essential to have the system inspected and repaired promptly to ensure the airbags will deploy correctly if needed.
Coolant Temperature Warning Light
The Coolant Temperature Warning Light indicates that the engine is overheating, which can cause severe damage if not addressed immediately.
This light often appears as a thermometer submerged in liquid. Overheating can be caused by low coolant levels, a faulty thermostat, or issues with the radiator.
When this light illuminates, stop driving immediately to prevent engine damage.
Check the coolant levels in the reservoir and top up if necessary.
If the coolant level is correct and the light remains on, seek professional help as there could be a more severe issue with the cooling system.
Transmission Temperature Warning Light
The Transmission Temperature Warning Light indicates that the transmission fluid is too hot, which can lead to transmission failure if not addressed.
This light usually appears as a thermometer inside a gear icon. High transmission temperatures can be caused by heavy towing, high ambient temperatures, or low transmission fluid levels.
When this light comes on, stop driving and let the transmission cool down. Check the transmission fluid levels and add fluid if needed.
If the light stays on, have the transmission inspected by a professional to prevent further damage.
Low Fuel Warning Light
The Low Fuel Warning Light indicates that the fuel level is low and the vehicle needs refueling soon.
This light typically appears as a gas pump icon.
It is advisable to refuel as soon as possible to avoid running out of fuel, which can leave you stranded and may cause damage to the fuel pump if the tank is consistently run dry.
Detailed Guide to Honda Dashboard Symbols
Green and Blue Dashboard Lights
Green and blue lights are typically informational and indicate that a system is operating as intended.
The turn signal indicators flash green when activated, the high beam light illuminates blue when the high beams are on, and the cruise control indicators light up green when the system is engaged.
These lights serve as reminders that these systems are in use and functioning correctly.
Yellow/Amber Dashboard Lights
Yellow or amber lights usually signify a system that needs attention but is not urgent.
The service engine soon light indicates that routine maintenance is required.
The traction control system light comes on when the system is activated or if there is an issue.

These lights indicate that attention is needed, but the vehicle can generally be driven safely until the issue is addressed.
Red Dashboard Lights
Red lights indicate a serious issue or safety concern that needs immediate action.
Examples include the brake warning light, which can signal low brake fluid or a more severe brake system issue, the engine temperature warning light indicating overheating, and the airbag warning light suggesting a problem with the airbag system.
When a red light appears, it is crucial to address the issue immediately to ensure the safety and functionality of the vehicle.
Maintaining Your Honda: Regular Check-Ups
Regular maintenance and checks are vital to ensure the longevity and performance of your Honda.
Following the manufacturer’s recommended maintenance schedule helps to keep the vehicle running smoothly and can prevent minor issues from becoming major problems.
Regularly checking fluid levels, including engine oil, coolant, brake fluid, and transmission fluid, ensures that the vehicle’s systems are properly lubricated and cooled.
Keeping tires inflated to the recommended pressure improves fuel efficiency, handling, and tire lifespan.
