For enhanced safety, the front seat shoulder belts of the Cadillac Lyriq 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 BMW X5 xDrive45e doesn’t offer height-adjustable seat belts.
Both the Lyriq and X5 xDrive45e have child safety locks to prevent children from opening the rear doors. The Lyriq 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 X5 xDrive45e’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 Lyriq are reminded to check the back seat if they opened the rear door before starting out. The X5 xDrive45e doesn’t offer a back seat reminder.
Both the Lyriq and X5 xDrive45e have rear cross-traffic warning, but the Lyriq has Rear Cross Traffic Braking (automatically applies the brakes) to better prevent a collision when backing near traffic. The X5 xDrive45e’s Cross Traffic Warning doesn’t automatically brake.
Both the Lyriq and the X5 xDrive45e have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras and rear cross-path warning.
