For enhanced safety, the front seat shoulder belts of the Honda Civic 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 Mercedes CLA doesn’t offer height-adjustable seat belts.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Civic are reminded to check the back seat if they opened the rear door before starting out. The CLA doesn’t offer a back seat reminder.
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 CLA’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 standard Low Speed Braking Control that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The CLA 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 CLA.
Both the Civic and the CLA have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, front wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, driver alert monitors, available blind spot warning systems, rear parking sensors and rear cross-path warning.
For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the Civic its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 101 vehicles tested by the IIHS. The CLA has not been tested, yet.
