Dashboard lights use colour to indicate their broad purpose, but colour alone is not a diagnosis. Red commonly means stop as soon as it is safe, amber or yellow normally means investigate promptly, and green or blue is usually informational. Read the accompanying message and use the handbook for the exact model year before deciding whether to continue driving.

Red Warnings (Stop the car immediately)

Engine Oil Pressure (oil can symbol): Stop as soon as it is safe and switch off the engine. Do not assume the cause from the symbol or repeatedly restart the car. Check the oil level only by following the handbook procedure on level ground; if the warning remains, the level is correct or oil loss is visible, arrange recovery and diagnosis.

Engine Temperature (thermometer in liquid): Pull over safely, switch off the engine and let it cool fully. Never open the coolant cap while the system is hot. Check the handbook before checking or adding coolant, and use recovery if the warning returns or coolant is being lost.

Brake System (circle with exclamation): This can indicate the parking brake is applied, low brake fluid or a braking-system fault. If it remains on after the parking brake is fully released, or appears with another brake warning, stop safely and obtain professional advice before continuing.

Amber/Yellow Warnings (Address within days)

Engine Management (engine symbol): A fault has been detected in the engine or emissions system. A steady amber light requires diagnosis; a flashing light, rough running, loss of power or unusual noise needs more urgent attention. Do not guess the failed component from the symbol alone: record the symptoms and have the stored fault codes read.

EPS (Electric Power Steering, steering wheel with exclamation): Power assistance may be reduced or unavailable, so the steering can require noticeably more effort. Fiat's handbook advises stopping safely, switching the engine off for about 20 seconds and restarting. If the warning remains, or the steering feels abnormal, have the car inspected as soon as possible. Do not disconnect the battery merely to clear the light.

Airbag System (airbag symbol): A fault may prevent airbags or seat-belt pretensioners operating correctly, or in rare cases could cause unintended operation. Fiat's handbook says the restraint system should be checked immediately. Do not assume a loose connector is the cause without diagnosis.

ABS (anti-lock braking symbol): Conventional braking may remain, but anti-lock assistance can be unavailable. Reduce speed, leave extra stopping distance and arrange prompt diagnosis. If the ABS light appears with a red brake warning, stop safely and seek professional advice.

Green/Blue Indicators and Other Messages

Hill Holder message or warning: A fault message means the assistance may be unavailable; it is not the same as a green confirmation that a system is active. Drive with appropriate care on slopes and arrange diagnosis if the message persists.

Seatbelt (seatbelt symbol): A seatbelt isn't buckled. Straightforward — fasten seatbelts and the light extinguishes.
