For enhanced safety, the front seat shoulder belts of the Kia Niro 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 GMC Terrain doesn’t offer height-adjustable seat belts.
The Kia Niro has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Terrain doesn’t offer knee airbags.
Over 200 people are killed each year when backed over by motor vehicles. The Niro EX/SX/Touring has standard Parking Collision-Avoidance Assist that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Terrain doesn’t offer backup collision prevention brakes.
The Niro has a standard blind spot warning system which 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 Terrain’s blind spot costs extra.
To help make backing out of a parking space safer, the Niro has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Rear cross-path warning costs extra on the Terrain.
The Niro’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Terrain doesn’t offer a driver alert monitor.
Both the Niro and the Terrain have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and available front and rear parking sensors.
