Every driver has experienced it: a warning light on the dashboard suddenly illuminates, causing a moment of panic and confusion. Understanding what these warning lights mean and knowing how to respond can make all the difference between a minor inconvenience and a major repair. At Luke's Auto Repair in Onalaska, WI, we're here to help you navigate these alerts and keep your vehicle running smoothly.

The Most Common Warning Lights

Check Engine Light

The check engine light is perhaps the most infamous and misunderstood of all the warning lights. This light can signal a variety of issues, from a loose gas cap to a more serious engine problem. If this light comes on, it’s important to get your car checked by a professional. Ignoring it can lead to more significant problems down the road.

Oil Pressure Warning

When the oil pressure warning light illuminates, it’s indicating that the oil pressure is too low. This could be due to a lack of oil, an oil leak, or a malfunctioning oil pump. Driving with low oil pressure can severely damage your engine, so it’s crucial to address this issue immediately.

Battery Alert

The battery alert light means that there’s an issue with the car’s electrical system, typically related to the battery or alternator. If this light comes on, your car may soon lose power. It’s wise to head to an auto repair shop as soon as possible to avoid getting stranded.

Brake System Warning

If the brake system warning light is illuminated, it can indicate a range of issues, from low brake fluid to a problem with the anti-lock braking system (ABS). Since brakes are essential for your safety, it’s critical to address any brake warnings immediately.

Less Common but Important Warning Lights

Tire Pressure Monitoring System (TPMS)

The TPMS light signals that one or more of your tires is significantly under-inflated. Driving on under-inflated tires can lead to poor handling, increased wear, and even blowouts. Check your tire pressure and inflate your tires to the recommended levels as soon as possible.

Coolant Temperature Warning

When the coolant temperature warning light comes on, your engine is overheating. This could be due to low coolant levels, a faulty thermostat, or a failing water pump. Overheating can cause severe engine damage, so it’s vital to pull over and let your engine cool down before seeking professional help.

Airbag Warning

The airbag warning light indicates a problem with one or more of your airbags. Since airbags are a crucial safety feature, it’s important to have this issue checked and repaired promptly to ensure they will deploy correctly in an accident.

What to Do When a Warning Light Comes On

• • Stay Calm: It’s easy to panic when a warning light comes on, but staying calm will help you make rational decisions.
• • Check Your Owner’s Manual: Your car’s owner’s manual provides valuable information about what each warning light means and how to respond.
• • Assess the Situation: Some warning lights require immediate attention, while others can wait until your next scheduled maintenance. Determine the urgency of the situation based on the light that’s illuminated.
• • Pull Over Safely: If a warning light indicates a severe problem, such as overheating or brake failure, pull over safely to avoid further damage or danger.
• • Contact a Professional: For most warning lights, it’s best to seek the help of a professional mechanic. At Luke's Auto Repair in Onalaska, WI, we have the expertise and equipment to diagnose and fix any issues your car may have.
