1. Check engine oil level: On a cool, level surface, pull out the dipstick, wipe it clean, reinsert fully, then pull out again to check the level. Add oil if needed.
2. Inspect for leaks: Look under the car for any fresh oil puddles.
When to Call a Pro: If the oil level is correct, or if adding oil doesn’t extinguish the light, do not drive the car. Have it towed to a mechanic.

Battery/Charging System Warning Light

A red light resembling a battery means there’s an issue with your vehicle’s charging system. This could be a failing alternator, a loose or corroded battery terminal, or a worn-out battery.

Initial DIY Steps:
1. Check battery terminals: Ensure they are clean and tight.
2. Inspect serpentine belt: Make sure it’s not loose or damaged, as it drives the alternator.
3. Test battery voltage: Use a multimeter to check battery voltage with the engine off (should be ~12.6V) and running (should be 13.5-14.5V).
Pro Tip: A failing alternator will often cause the battery light to come on, and your car may eventually die as the battery runs out of charge.

Brake System Warning Light

This red light, often an exclamation mark within a circle (or the word “BRAKE”), indicates a problem with your braking system. It could be the parking brake engaged, low brake fluid, or a more serious issue like a faulty master cylinder.

Action: If the parking brake is not engaged, pull over safely.
Initial DIY Steps:
1. Check parking brake: Ensure it’s fully disengaged.
2. Inspect brake fluid level: Locate the brake fluid reservoir under the hood and ensure the fluid is between the MIN and MAX lines. If low, check for leaks.
When to Call a Pro: Any brake system warning should be taken seriously. If the light persists after checking the parking brake and fluid, have your car inspected immediately. Do not drive if you suspect a brake failure.

ABS (Anti-lock Braking System) Light

A yellow light with “ABS” indicates a problem with your anti-lock braking system. While your regular brakes will still work, the ABS function (preventing wheel lock-up during hard braking) may be disabled.

Common Causes: Faulty wheel speed sensor, ABS module failure, low brake fluid.
Initial DIY Steps:
1. Check brake fluid: As with the main brake light.
2. Inspect wheel speed sensors: Look for visible damage to the wiring or sensor itself at each wheel.
Pro Tip: This light often comes on in conjunction with the VSA light.

SRS (Supplemental Restraint System) / Airbag Light

A red light depicting a person with an airbag deployed indicates a fault in your airbag system. This means the airbags may not deploy in a collision, or they could deploy unexpectedly. This is a critical safety warning.

Action: Do not ignore this light.
When to Call a Pro: Due to the complexity and safety implications, SRS system issues should always be diagnosed and repaired by a qualified technician. Avoid DIY attempts here.

TPMS (Tire Pressure Monitoring System) Light

A yellow light shaped like a flat tire with an exclamation mark means one or more of your tires has significantly low pressure. This impacts safety, fuel economy, and tire longevity.

Initial DIY Steps:
1. Check all tire pressures: Use a reliable tire pressure gauge. Inflate tires to the recommended PSI (found on a sticker inside your driver’s side door jamb).
2. Inspect for punctures: Look for nails, screws, or other damage.
Pro Tip: Remember to check the spare tire pressure too, if applicable, though the 2013 Accord TPMS typically only monitors the four main tires. Sometimes the light takes a few miles of driving to reset after correcting pressure. This is a great example of 2013 Honda Accord dash lights tips for simple maintenance.

VSA (Vehicle Stability Assist) Light

A yellow light showing a car skidding usually means there’s an issue with your Vehicle Stability Assist system, which helps maintain traction and control. It often comes on with the ABS light.

Common Causes: Faulty wheel speed sensor, steering angle sensor issue, VSA modulator problem.
