The first missing feature is the ADAS. Very recently, the XUV300 Facelift was spotted with ADAS Module, and it’s possible it could limited ADAS features such as Lane Departure Warning, Forward Collision Warning, Lane Keep Assist, and few more. However, it unlikely it’ll get Adaptive Cruise Control.
The current XUV300 already comes with Front Parking Sensors but it’s not present in the Creta. The Parking Sensors helps you park the safely by alerting you if you're about to hit or too close to an obstacle.
The Creta misses on the 2-zone Climate Control which at the moment Seltos has but no rivals of XUV300 are offering, so that makes it somewhat special.
The 4th feature is the Rain-Sensing Wipers which big SUV like Creta should have been offered, but it misses.
