For enhanced safety, the front seat shoulder belts of the Cadillac XT5 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 GLA 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 XT5 are reminded to check the back seat if they opened the rear door before starting out. The GLA doesn’t offer a back seat reminder.
Over 200 people are killed each year when backed over by motor vehicles. The XT5 Premium Luxury/Sport offers optional Reverse Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The GLA doesn’t offer backup collision prevention brakes.
A passive infrared night vision system optional on the XT5 Premium Luxury/Sport helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The GLA doesn’t offer a night vision system.
The XT5’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 GLA.
Both the XT5 and the GLA have standard driver and passenger frontal airbags, front side-impact airbags, driver knee 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, rearview cameras, available all wheel drive, blind spot warning systems, around view monitors and rear cross-path warning.
The Cadillac XT5 weighs 421 to 954 pounds more than the Mercedes GLA. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the XT5 the rating of “Top Safety Pick” for 2017, a rating granted to only 203 vehicles tested by the IIHS. The GLA has not been tested, yet.
