Both the XF and E-Class Sedan have child safety locks to prevent children from opening the rear doors. The XF 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 E-Class Sedan’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.
When descending a steep, off-road slope, the XF’s standard All Surface Progress Control allows you to creep down safely. The E-Class Sedan doesn’t offer All Surface Progress Control.
The XF’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 E-Class Sedan.
To help make backing out of a parking space safer, the XF has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Rear cross-path warning costs extra on the E-Class Sedan.
Both the XF and the E-Class Sedan have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, driver alert monitors and available all wheel drive.
