Crash Test Performance:
Early Uno models had modest safety standards by modern comparison. Later models incorporated some safety improvements, but Euro NCAP testing was not prevalent during its early production years.
Braking System:
Front disc brakes, rear drum brakes. ABS was not a standard feature on most models.
Seatbelts:
Standard front seatbelts. Rear seatbelts were optional or standard depending on market and year.
Airbags:
Driver airbag became available on later models in some markets, but was not a widespread standard feature during most of its production run.
Original Infotainment Features:
Basic AM/FM radio with cassette player was common. Optional air conditioning was available on higher trims and later models.
Driver Assistance Features:
Minimal by modern standards. Features like power steering, anti-lock braking systems (ABS), and airbags were either optional or introduced later in the model's life cycle and not universally equipped.
Connectivity Features:
No integrated connectivity features like Bluetooth or USB were available on original models.
Oil Change Interval:
Typically every 7,500 - 15,000 km (4,500 - 9,000 miles) or 6-12 months, depending on driving conditions and oil type used.
Air Filter Replacement:
Every 15,000 - 30,000 km (9,000 - 18,000 miles) or as needed based on inspection.
