For enhanced safety, the front and second-row seat shoulder belts of the Mercedes EQB have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The MINI Countryman SE doesn’t offer pretensioners for its rear seat belts.
The EQB’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Countryman SE doesn’t offer pre-crash pretensioners.
For enhanced safety, the front seat shoulder belts of the Mercedes EQB are height-adjustable to accommodate a wide variety of driver and passenger heights.
