For enhanced safety, the front and rear seat shoulder belts of the Honda Civic 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 Kia Rio doesn’t offer pretensioners for its rear seat belts.
The Honda Civic 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.
Using vehicle speed sensors and seat sensors, smart airbags in the Civic deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The Civic’s side airbags will shut off if a child is leaning against the door. The Rio’s side airbags don’t have smart features and will always deploy full force.
Over 200 people are killed each year when backed over by motor vehicles. The Civic Touring/Sport Touring has a standard Low Speed Braking Control that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Rio doesn’t offer backup collision prevention brakes.
The Civic’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the Rio and is only available on Rio S.
The Civic EX/EX-L/Touring/Sport Touring’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 Civic Touring/Sport Touring’s standard Cross Traffic Monitor uses sensors in the rear to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Rio doesn’t offer a rear cross-path warning system.
Both the Civic and the Rio have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front wheel drive, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras and available rear parking sensors.
For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, and daytime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the Civic the rating of “Top Safety Pick” for 2023, a rating granted to only 53 vehicles tested by the IIHS. The Rio last would have qualified as a “Top Safety Pick” in 2018.
