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 and moves the vehicle back into its lane. 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, daytime running lights, driver alert monitors and available around view monitors.
