Dashboard Warning Lights: Which Are Urgent?
Your vehicle's dashboard is full of symbols. When one lights up, it's easy to panic — or to ignore it. Both reactions can be wrong.
At the shop, we'll give you a simple guide: which lights require an immediate stop, which need a quick appointment, and which are just informational.
RED Lights: Pull Over
- Engine temperature: risk of overheating. Pull over immediately.
- Oil pressure: engine may lack lubrication. Turn off the engine.
- Parking brake / brake system: check that the parking brake is released. If the light persists, get your brakes checked.
- Battery / alternator: charging system not working. You have limited time before the battery dies.
ORANGE Lights: Book Soon
- Check engine: steady = book this week. Flashing = urgent.
- ABS: anti-lock system has a problem. Your basic brakes still work.
- TPMS (tire pressure): a tire is under-inflated. Check pressure.
- Airbag: passive safety system fault. Get checked.
YELLOW / Informational Lights
- Low fuel: fill up soon.
- Washer fluid: refill the reservoir.
- Maintenance required: scheduled maintenance reminder.
Key Takeaways
- Red = pull over. Orange = book soon. Yellow = informational.
- Never ignore a red warning light.
- Check engine is the most common — rarely an immediate emergency if steady.
- A diagnostic costs $50–$100 and can prevent thousands in repairs.
- Also check your alignment if TPMS lights up often.
