(Option/accessory.)

Control in the center display's Function view if the vehicle is not equipped
with a drive mode control in the tunnel console.
Selecting Low Speed Control in the center display's Function view
- Tap the Hill Descent Control button to activate or deactivate the
function.

- An indicator light in the button will illuminate when the function is
activated.
When the engine is switched off, the function will be automatically deactivated.
NOTE
The function is deactivated when driving at high speeds and must be reactivated
at lower speeds if so desired.
The low-speed function (LSC1) facilitates and improves control
and traction on rough roads and slippery surfaces, e.g. when towing a trailer on
grass or up boat ramps...
(Option/accessory.)
The function for assisting when driving downhill (HDC1) is a low-speed
function with increased engine braking. The function makes it possible to increase
or decrease the vehicle's speed on steep downhill gradients by only using the accelerator
pedal, without applying the brakes...
