The Nissan Versa has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Rio doesn’t offer knee airbags.
Over 200 people are killed each year when backed over by motor vehicles. The Versa has standard Rear Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Rio doesn’t offer backup collision prevention brakes.
The Versa’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 Rio and is only available on Rio S.
The Versa SV/SR’s blind spot warning system uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The Rio doesn’t offer a system to reveal objects in the driver’s blind spots.
To help make backing out of a parking space safer, the Versa SV/SR’s standard rear cross-path warning system uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Rio doesn’t offer a cross-path warning system.
Both the Versa and the Rio have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, rearview cameras, available daytime running lights and driver alert monitors.
