Electronic Damper Control (EDC)* and Ride Height Adjustment
The system automatically provides the required suspension damping at all times, contributing to greater ride comfort and driving safety.
Automatic adjustment
Automatic adjustment is activated after each engine start. It remains active across the entire vehicle speed range and at any vehicle load. If driving conditions change (road surface, cornering, braking, etc.), the damping force is automatically adjusted to the changed conditions within fractions of a second.
Sport program

Sport program
To activate it, turn the ignition key to position 2 and press the EDC button (shown by the arrow). The indicator lamp next to the letter S will light up.
Activate the sport program if you prefer a sporty driving style under any operating conditions.
Switching back to automatic adjustment
Press the button again; the indicator lamp will go out.
Ride height adjustment*
The control unit installed on the rear axle maintains a constant ride height regardless of vehicle load.

Ride height adjustment
For this purpose, air suspension struts are installed on the rear axle instead of conventional shock absorbers and steel springs. The electronic control system uses two sensors to determine the actual height of the body above the road and, when necessary, activates the compressor, which pumps compressed air into the struts.
By increasing the pressure as the load increases, the system not only maintains a constant ride height but also provides comfortable damping during driving regardless of vehicle load.
