Questions and Answers

Key insights from this episode to help you understand and respond to your vehicle’s warning lights.

What do different colored warning lights mean in a car?

Red lights typically indicate a serious issue that requires immediate attention, such as engine overheating or low oil pressure. Yellow or amber lights usually signal a less urgent problem, meaning you can often continue driving cautiously. Green lights generally indicate that a system is active and functioning normally.

Is it safe to drive with a check engine light on?

If the check engine light is solid and there are no unusual symptoms, you can usually finish your trip. However, you should have the vehicle checked as soon as possible. If the light is flashing, it indicates a more serious issue that could cause damage if you keep driving.

What should I do if my oil pressure warning light comes on?

You should pull over and turn off the engine immediately. Driving with low oil pressure can cause severe engine damage. It’s best to have the vehicle towed and inspected rather than risk costly repairs.

Why is the temperature warning light so important?

A temperature warning light indicates your engine is overheating. Continuing to drive can destroy the engine. Pull over safely, shut the car off, and allow it to cool before seeking repairs.

What does a flashing check engine light mean?

A flashing check engine light usually signals a severe issue like an engine misfire. This can damage components such as the catalytic converter. You should stop driving and have the vehicle inspected immediately.

Why does my tire pressure (TPMS) light come on in cold weather?

Cold temperatures cause air pressure inside your tires to drop. This can trigger the TPMS light even if there’s no leak. As the tires warm up while driving, the pressure may increase and turn the light off.

What does the airbag warning light indicate?

An airbag light means there may be a problem with the vehicle’s safety restraint system. In an accident, the airbags or seatbelt systems may not function properly. It’s important to have this checked quickly.

Can I ignore a low fuel warning light?

Running your vehicle consistently on low fuel can damage the fuel pump over time. The pump relies on fuel for cooling, so letting the tank run too low can shorten its lifespan and lead to expensive repairs.

What are driver assistance warning lights?

These lights relate to systems like lane assist, collision avoidance, and blind spot monitoring. They may change colors depending on system status. If they turn red or display an error, the system may not be functioning properly.

Should I rely only on my car’s maintenance reminder lights?

Maintenance lights are helpful reminders, but they shouldn’t replace regular service intervals. It’s best to follow a consistent schedule for oil changes and inspections rather than waiting solely for a warning light.
