For enhanced safety, the front and middle seat shoulder belts of the Mercedes GLS 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 SRT doesn’t offer pretensioners for the middle seat belts.

The GLS’ pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Durango SRT doesn’t offer pre-crash pretensioners.

When descending a steep, off-road slope, the GLS’ standard Downhill Speed Regulation allows you to creep down safely. The Durango SRT doesn’t offer Downhill Speed Regulation.

The GLS has a standard Surround View System to allow the driver to see objects all around the vehicle on a screen. The Durango SRT 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 GLS and the Durango SRT 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, all wheel drive, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras and available lane departure warning systems.

Unlike the driver-only memory system in the Durango SRT, the GLS has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, suspension setting, power steering assist, outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.
