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 Dodge Durango doesn’t offer pretensioners for its second-row 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 Durango doesn’t offer pre-crash pretensioners.
When descending a steep, off-road slope, the GLB’s standard Downhill Speed Regulation allows you to creep down safely. The Durango doesn’t offer Downhill Speed Regulation.
The GLB offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The Durango only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
Both the GLB and Durango have rear cross-traffic warning, but the GLB has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Durango’s Rear Cross Path Detection doesn’t automatically brake.
The GLB’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 Durango doesn’t offer a driver alert monitor.
Both the GLB and the Durango have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive and lane departure warning systems.
