Your dashboard is your car’s way of telling you something is wrong. Ignoring those warning lights may seem harmless at first, but it could turn an easy fix into an expensive car repair in Salem, NH. 

Here at Ray’s Auto Repair, we’ve seen it one too many times. One of the biggest reasons drivers ignore dashboard warning lights is because they believe they’re just that, a warning. If the car still drives fine and there aren’t any strange noises, the problem can’t be that serious…right?

Or maybe you drive an older vehicle that’s known for having warning lights on all the time. That check engine light that’s been glowing for months is probably just another false alarm.

Unfortunately, that’s rarely the case.

Then there’s the other major reason people ignore problems: the cost. It’s easy to get caught in the never-ending cycle of needing your car to get to work, needing work to pay for the repair, and needing the repair to keep your car running. It can feel impossible to find the right time to bring your vehicle into the shop.

The truth is, tackling a problem early almost always saves money in the long run. However, if you’re trying to prioritize certain repairs because of your schedule or budget, it helps to understand what your dashboard is trying to tell you.

 

Understanding Your Dashboard

Your vehicle’s Engine Control Unit (ECU) is constantly monitoring thousands of pieces of information, including engine temperature, fluid levels, tire pressure, emissions, battery charging, and much more.

When something falls outside of its normal operating range, the ECU alerts you with a dashboard warning light.

If the same warning light continues to return even after a repair, ask your mechanic to inspect the sensors and wiring. Sometimes the issue is as simple as a faulty sensor or damaged wiring, occasionally even caused by rodents chewing through electrical wires.

Dashboard Color Codes

Dashboard lights are color-coded depending on urgency.

• Green or Blue – A vehicle feature is currently active, such as your headlights or cruise control.
• Yellow or Amber – A warning that should be inspected soon. The vehicle may still be safe to drive, but service should be scheduled.
• Red – A serious problem that calls for immediate attention. Pull over safely as soon as possible and determine whether the vehicle should continue to be driven.

 

Check Engine Light

The check engine light usually looks like the outline of an engine, and it’s the warning nobody wants to see.

This light can indicate anything from a loose gas cap to worn spark plugs, an emissions issue, or even a failing catalytic converter. Because it’s connected to multiple engine and emissions systems, it’s impossible to know the exact cause without a diagnostic scan.

While some causes are minor, ignoring the light can eventually lead to more expensive repairs. When in doubt, it’s always better to have it inspected sooner rather than later.

 

Battery Charging Warning Light

This warning light resembles a battery with a plus (+) and minus (-) symbol.

If this light appears while you’re driving, your vehicle may be running solely on the remaining charge in the battery because the charging system isn’t working properly.

Possible causes include:

• A failing alternator
• A worn or broken serpentine belt
• Loose or corroded battery terminals
• A failing battery

If possible, head directly to your local mechanic before the battery loses enough power to shut the vehicle off.

 

Tire Pressure Monitoring System (TPMS)

The TPMS warning light looks like a horseshoe with an exclamation point in the center.

If the light is solid, one or more tires are either underinflated or overinflated.

If the light is blinking, there’s likely a fault within the TPMS system itself.

Don’t be surprised if this light comes on during a cold morning and disappears later in the day. Cold temperatures cause air pressure inside your tires to decrease. As the tires warm up while driving, the pressure naturally increases.

If you’ve adjusted your tire pressure and the warning light stays on, it’s time to have the system inspected.

 

Coolant Temperature Warning

This warning light looks like a thermometer dipping into water.

Your vehicle’s coolant regulates engine temperature by absorbing heat from the engine and carrying it through the radiator, where the heat is released.

If this light comes on, safely pull over and turn off the engine as soon as possible. Continuing to drive an overheating engine can cause severe damage.

Low coolant is one of the most common causes, and topping it off may solve the problem. However, overheating can also be caused by:

• A leaking coolant hose
• A broken water pump
• A damaged radiator
• A stuck thermostat

 

Brake System Warning

This warning light is usually a circle with an exclamation point inside.

Sometimes the solution is simple, such as forgetting to fully release your parking brake.

However, this warning can also indicate:

• Low brake fluid
• Worn brake pads
• A hydraulic brake system issue
• A problem with the anti-lock braking system (ABS)

Since your brakes are one of your vehicle’s most important safety systems, don’t ignore this warning.

 

Traction Control Warning Light

This light appears as a car icon with swerving skid marks underneath the tires.

The traction control light usually flashes briefly whenever your tires lose grip, such as during rain, snow, or icy conditions. This is completely normal, and it means the system is actively helping you maintain traction.

If the light stays on continuously, however, there may be a problem with the traction control or stability control system. While your vehicle will usually still drive, you may have less assistance keeping control during slippery conditions.

Having the system inspected can help keep your vehicle as safe as possible.
