1. Scheduled Maintenance: The spanner symbol illuminates to indicate that your car is due for scheduled maintenance or servicing, as recommended by the manufacturer. For the Fiat Punto, this typically occurs at regular intervals based on the vehicle's mileage or time. When the spanner light turns on, it's important to take your car to an authorized Fiat service center or a reputable mechanic for the necessary maintenance tasks, such as oil changes, brake inspections, tire rotations, and filter replacements.
2. System Malfunction or Error: In some cases, the spanner symbol may also appear to indicate a system malfunction or an error in one or more of the vehicle's electronic components. This can include issues related to the engine, transmission, brakes, or other key systems. When this is the case, the spanner light may be accompanied by additional warning lights, such as the check engine light or the ABS (anti-lock braking system) light. If the spanner symbol is accompanied by other warning lights, it is essential to have the car diagnosed by a qualified mechanic as soon as possible to identify and address the underlying problem.
