Unlike the driver-only memory system in the Nautilus, the GLB has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, 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.
The GLB offers an optional heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Nautilus doesn’t offer a heads-up display.
The power windows standard on both the GLB and the Nautilus have locks to prevent small children from operating them. When the lock on the GLB is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Nautilus prevents the driver from operating the rear windows just as it does the other passengers.
The GLB’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Nautilus’ cruise control switches are unlit, making them difficult to find at night and operate safely.
The GLB’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Nautilus’ standard manually variable intermittent wipers have to be constantly adjusted.
Heated windshield washer nozzles are optional on the GLB to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Nautilus doesn’t offer heated windshield washer nozzles.
When the GLB is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Nautilus’ mirror doesn’t automatically adjust for backing.
To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mercedes GLB has a standard wireless phone charging system (Qi) in the center console. Only the Nautilus Reserve/Black Label offers wireless charging.
The GLB’s Active Parking Assist can parallel park by itself, stopping and changing direction automatically. The Nautilus (except Standard)’s automatic parking system requires operating the brakes and transmission to safely park.
