For enhanced safety, the front and middle seat shoulder belts of the Hyundai Palisade 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 GLB doesn’t offer height-adjustable middle seat belts.
Both the Palisade and GLB have child safety locks to prevent children from opening the rear doors. The Palisade has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The GLB’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
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 Palisade are reminded to check the back seat. The GLB doesn’t offer a back seat reminder.
The Palisade has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The GLB doesn’t offer front seat center airbags.
Over 200 people are killed each year when backed over by motor vehicles. The Palisade SEL Premium/XRT/Limited/Calligraphy/Hybrid has standard Parking Collision Avoidance Assist that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The GLB doesn’t offer automatic braking for stationary objects directly to the rear.
The Palisade’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 GLB.
The Hyundai Palisade’s rear backup camera has a standard washer for maintaining a clear view under various conditions. In contrast, the Mercedes GLB does not offer a rear camera washer, meaning its effectiveness relies on manual cleaning by the user when necessary.
Both the Palisade and the GLB have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, 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, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors, available all wheel drive and around view monitors.
The Hyundai Palisade weighs 529 to 1234 pounds more than the Mercedes GLB. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
