For enhanced safety, the front and rear seat shoulder belts of the Nissan Sentra 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 Cooper Hardtop 4 Door doesn’t offer pretensioners for its rear seat belts.
For enhanced safety, the front seat shoulder belts of the Nissan Sentra are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The MINI Cooper Hardtop 4 Door doesn’t offer height-adjustable seat belts.
The Sentra’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. A lane departure warning system costs extra on the Cooper Hardtop 4 Door.
The Sentra has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Cooper Hardtop 4 Door’s blind spot costs extra.
To help make backing out of a parking space safer, the Sentra has standard Rear Cross Traffic Alert, helping the driver avoid collisions. MINI charges extra for Cross Traffic Warning on the Cooper Hardtop 4 Door.
Both the Sentra and the Cooper Hardtop 4 Door have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, rearview cameras, driver alert monitors, available daytime running lights and around view monitors.
