Both the EV6 and EQS have child safety locks to prevent children from opening the rear doors. The EV6 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 EQS’ 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 EV6 are reminded to check the back seat if they opened the rear door before starting out. The EQS doesn’t offer a back seat reminder.

Both the EV6 and the EQS have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, 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, rear cross-path warning, driver alert monitors and available around view monitors.
