Additional Notes
- The rear differential on the Chang'an Honor / Ounuo holds 1.4 liters of fluid, a figure that applies uniformly across both the 1.3 and 1.5 engine variants built on the SC6449 platform from 2012 onward.
- A 1.4-liter fill volume for a rear differential is a relatively modest capacity, consistent with the compact dimensions typical of light passenger vehicles in this segment.
- Under normal use conditions, the rear differential fluid change interval is set at 5,000 km for both engine variants, reflecting a relatively short cycle by general automotive standards.
- A separate first-change-only interval of 2,500 km or 1 month is specified for the rear differential on both the 1.3 and 1.5 variants. First-change intervals exist to flush out metal particles and manufacturing residues that accumulate during the initial break-in period of gear components.
- The 1-month time limit attached to the first-change-only interval means the fluid replacement is triggered by whichever threshold, distance or time, is reached first, ensuring early servicing even in low-mileage usage scenarios.
- No variation in rear differential fluid capacity or change intervals exists between the 1.3 and 1.5 engine configurations, indicating the same rear axle assembly is shared across both powertrain options within the SC6449 body.
