For enhanced safety, the front and second-row seat shoulder belts of the Mercedes GLB 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 Sportage Hybrid doesn’t offer pretensioners for its rear seat belts.
The GLB’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Sportage Hybrid doesn’t offer pre-crash pretensioners.
The Mercedes GLB 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 Sportage Hybrid doesn’t offer knee airbags.
The GLB 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. Only the Sportage Hybrid EX/SX-Prestige offers a blind spot warning system.
To help make backing out of a parking space safer, the GLB has standard Rear Cross-Traffic Alert and Active Brake Assist automatically engages the brakes to help avoid a collision. Only the Sportage Hybrid EX/SX-Prestige offers Rear Cross-Traffic Collision Warning.
Both the GLB and the Sportage Hybrid have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, driver alert monitors, available all wheel drive, lane departure warning systems and around view monitors.
