HDC is a system for driving downhill in steep 
terrain. This system reduces vehicle speed on 
steep downhill gradients, thus allowing you to 
maintain even better control of your BMW 
under these conditions. The vehicle moves at 
approximately twice walking speed without 
active intervention from the driver.
HDC is available for activation at vehicle speeds 
below approx. 22 mph/35 km/h. When driving 
down steep hills with a speed below approx. 
22 mph/35 km/h, the vehicle reduces speed 
automatically down to approximately double 
walking speed, approx. 7 mph/12 km/h, and 
then maintains this speed at a constant.
You can use the accelerator or brakes to vary 
this automatically controlled speed within a 
range extending from approx. 3 mph/5 km/h to 
15 mph/25 km/h.
You can specify a target speed within the same 
range by using the lever of the cruise control.

You can activate HDC:

>

with the programmable buttons on the 
steering wheel, refer to page

or via iDrive

iDrive, for explanation of principle, refer to
