The GL-Class possesses security equipment which promotes relaxed motoring and helps you to bring critical situations under control. This is immediately apparent in the exceptionally ergonomic styling of an interior whose every switch and function is simple to use. And thanks to intelligent equipment like the COMAND APS control and display system or the LINGUATRONIC voice-operated control system (both available as optional extras), you don't even have to take your hands off the steering wheel. Climate control and seating comfort also help ease the strain on the driver, as does a precision-tuned chassis.

Out on the road, more than 60 electronic aids are on standby, ready to either warn you as and when appropriate – such as the tyre pressure loss warning system – or actively come to your assistance. Leading the way is the Electronic Stability Program ESP®. Capable of stabilising the vehicle when there is a risk of skidding, this system received its premiere in a Mercedes. The braking systems featuring BAS Brake Assist are becoming increasingly intelligent too: based on the speed with which you depress the brake pedal, BAS is able to detect emergency braking and instantly build up maximum brake pressure in response to bring the vehicle to a halt sooner

Your field of vision is furthermore brightly illuminated at night in the GL-Class by the projector-beam halogen headlamps. For even greater clarity of vision, bi-xenon headlamps with an active light function can be specified as an option. The active light function pivots the headlamps to follow the movement of the steering wheel into a bend, which improves illumination of the road ahead by as much as nearly 100%. In a bend with a radius of 180 metres, for instance, the illuminated section of road is extended from approx. 30 to 55 metres. During an emergency stop, the adaptive brake lights flash as a warning to drivers behind.

In the GL-Class, the Electronic Stability Program (ESP®) assists the driver, while towing has now been made far safer by the inclusion of a trailer stabilisation function: if the trailer starts swinging back and forth, the ESP® trailer stabilisation recognises the problematic driving situation and applies short brake actuation to immediately stop the trailer movement.
