Red lights usually mean stop safely and investigate. Amber lights usually mean get service soon. The oil pressure, engine temperature and brake lights deserve immediate attention, and the battery and check engine lights come next.
Key takeaways
- Red means act now.
- Amber means service soon.
- When unsure, call.
Red lights
Oil pressure, engine temperature and brake system warnings. Pull over and shut off the engine if oil pressure or temperature warnings appear.
Battery light
The charging system is not working properly. Reduce electrical loads and head for help.
Check engine and ABS
Amber lights that need service soon. A flashing check engine light is urgent.
Tire pressure
Check pressure, since heat changes pressure.
What to do
Take a photo of the dash and call.
Colors and what they signal
Most manufacturers use red for urgent problems and amber or yellow for items that need service soon. Green or blue lights are informational, such as headlights or cruise control. Knowing this lets you triage in seconds. A red oil can or thermometer icon means act now. An amber engine icon means schedule service. When two or more lights appear at once, suspect a charging system problem.
Lights that appear together
A battery light, a power steering light and an ABS light appearing together often point to low system voltage from a failing alternator or a loose battery connection. Fixing the charging problem clears them. A mixed set of random lights after a battery replacement may be a computer that needs to relearn. Photograph the dash and bring the picture to the shop.
