Dashboard warning lights

Pick a light to see a short, safety-first summary. Symbols vary by manufacturer—use this as guidance, not a substitute for your owner’s manual or a workshop scan.

Type a symptom, fault code, or part. Use ↓ ↑ to move, Enter to select.

What colors usually mean

Symbols differ, but color is a useful priority signal.

🔴 Red

Often means stop and investigate soon—especially oil, coolant, and brake-related warnings.

🟡 Amber

Plan a check; raise urgency if you feel power loss, misfire, or new noises.

🟢 Green / blue

Usually status indicators (lights on, high beam, etc.).

Common warnings

Oil pressure warning

High priority

Low oil pressure may damage the engine quickly.

Stop safely, check oil level if you can do so safely, and avoid high load until a professional checks the system.

Check engine light

Check soon

A fault is stored; severity depends on symptoms.

Not always urgent, but power loss, flashing light, or new noises raise priority—use the guided flow for context.

Coolant / overheating warning

High priority

Cooling system may be overstressed.

Do not push the engine; stop safely, allow cool-down, and seek help if temperature stays high or steam appears.

ABS warning

Check soon

Anti-lock support may be limited.

Brakes can still work, but stability control may be reduced—adjust driving on slippery roads.

Battery / charging warning

High priority

Charging problem; the vehicle may stop unexpectedly.

Check belt tension signs if safe; plan for alternator/battery testing before long trips.

ESP / traction control

Check soon

Stability assist may be off or reporting a fault.

Sometimes a transient sensor issue; if it stays on, review tires and brakes with a workshop.

Indicator / beam tell-tale

Info

Usually informational.

Confirms which exterior light is active; consult the owner’s manual for the exact symbol.

Not sure which light it is?

Combine symptoms, codes, and vehicle context—the guided flow is built for that.
