Both the Defender 110/130 and GLC have child safety locks to prevent children from opening the rear doors. The Defender 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 GLC’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.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Defender. But it costs extra on the GLC.
The Defender’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 GLC.
Both the Defender and the GLC 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, rear cross-path warning and driver alert monitors.
