Hill Descent Control
Fig. 1 In the centre console: Button for switching the Hill
Descent Control on and off.
The Hill Descent Control system supports the driver when driving down a steep incline by actively braking the
vehicle.
Hill Descent Control reduces the engine speed and actively applies the brakes to keep the vehicle speed to a constant
walking pace →
.
The requirement for regulation is, among other things, that the ground allows enough grip. The Hill Descent Control
system cannot fulfil its function when driving down an icy or slippery slope.
Switching Hill Descent Control on and off
—To switch the Hill Descent Control on, press the → Fig. 1 button in the centre console at speeds under
approximately 30 km/h (19 mph). The indicator lamp in the instrument cluster display lights up grey. The system
is switched on, but is not regulating.
The indicator lamp lights up white when Hill Descent Control is active.
—Press the
button → Fig. 1 in centre console again to switch off the Hill Descent Control. The indicator lamp in
the instrument cluster display goes out.
Hill Descent Assist is regulating
—If Hill Descent Control is switched on using the button and the indicator lamp lights up white.
—And: if the speed is less than 30 km/h(19 mph).
—And: if the gradient is at least 10%.
—And: if the accelerator and brake are not depressed.
—And: if the engine is running.
Regulation is stopped if the vehicle is accelerated or braked by the driver during regulation. The regulation restarts
once the requirements are met again.
Hill Descent Assist does not regulate
—If the gradient is less than 10%.
—Or: speed is greater than 30 km/h(19 mph).
—Or: if the driver brakes or accelerates.
