Dashboard light decoder
Seeing one of these? Let’s take a look.
No jargon, no scare tactics — here’s what those dashboard lights usually mean, and when it’s worth a call.
-
Check Engine
The engine or emissions system flagged a fault — anything from a loose gas cap to a sensor.
Don't wait it out — small faults get pricey fast.
-
Brake Warning
Low brake fluid or worn pads asking for a look before they get worse.
Brakes are the one system worth checking today.
-
Temperature
Your engine is running hotter than it should be.
Pull over safely — overheating can crack an engine.
-
Oil Pressure
Oil is low or not circulating the way the engine needs.
Stop soon — running low ruins an engine quickly.
-
Battery
The battery or alternator isn't keeping the charge up.
Get it tested before it leaves you stranded.
-
Tire Pressure
One or more tires is low on air — the TPMS is watching.
Low tires wear fast and hurt your handling.
