Additional Notes
- The Chang'an Honor / Ounuo manual transaxle fluid capacity differs between the two engine variants. The 1.3-liter SC6449 holds 1.3 liters, while the 1.5-liter SC6449 holds 1.5 liters, reflecting a direct relationship between engine displacement and transaxle fluid volume in both configurations starting from 2012.
- Under normal use conditions, both the 1.3-liter and 1.5-liter SC6449 transaxle specifications call for a fluid change interval of 5,000 km, which is a relatively short interval by general automotive standards and points to a conservative maintenance schedule for the manual transaxle.
- A first-change-only interval is specified for both SC6449 variants, set at 2,500 km or 1 month, whichever comes first. A first-change-only interval is an initial service performed shortly after a new or rebuilt unit enters service, intended to flush out metal particles and manufacturing residues that accumulate during the break-in period.
- The first-change-only interval of 2,500 km is exactly half the normal 5,000 km change interval for both the 1.3-liter and 1.5-liter SC6449 configurations, meaning the break-in service falls at the midpoint of what would otherwise be a standard service cycle.
- The addition of a 1-month time limit alongside the 2,500 km distance in the first-change-only specification means the fluid change is due at whichever threshold is reached first, accommodating low-mileage usage patterns where the distance trigger might not be reached quickly.
- Both the 1.3-liter and 1.5-liter SC6449 transaxle entries are classified as transaxle, manual, indicating a combined transmission and axle unit, which is a common layout in front-wheel-drive vehicles where the gearbox and differential share a single housing and, in many cases, a shared fluid volume.
