🛡️ Safety Features

Euro Ncap Rating:

4 Stars (for adult occupant protection) in 2005, reflecting its segment and design era. Pedestrian safety was rated lower.

Active Safety Features:

Anti-lock Braking System (ABS) with Electronic Brake-force Distribution (EBD) and Brake Assist (BA) were typically available, especially on higher trims. Traction Control System (TCS) may have been optional or standard on certain configurations.

Passive Safety Features:

Front airbags, side airbags (optional or standard depending on trim), seat belt pretensioners, ISOFIX child seat mounting points.

DOT 4 brake fluid.

Transmission Fluid Manual:

API GL-4, SAE 75W-80 or 75W-90 gear oil. Consult manual for exact type and capacity.

Common Issues:

Potential issues include clutch wear (especially in city driving with the automated manual), minor electrical gremlins, and some bodywork corrosion on older models if not maintained. The 3-cylinder engine can exhibit a characteristic vibration, which is normal but can be perceived as rough by some. Early models may have experienced some issues with the automated manual gearbox engaging smoothly.
