Hill Descent Control (HDC)

The concept

HDC is a system for driving downhill in
steep terrain. This system reduces
vehicle speed on steep downhill gradi-
ents, thus allowing you to maintain
control of your BMW under these
conditions.
The vehicle moves at slightly more than
walking speed without active interven-
tion from the driver.

HDC is available for activation at
vehicle speeds below approx. 20 mph
(35 km/h). When driving down steep
hills with a speed below approx.
20 mph (35 km/h), the vehicle reduces
speed automatically down to slightly
more than walking speed (approx.
5 mph/8 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 use the +/– button to set the
cruise control to a target speed in the
range from approx. 3 mph (5 km/h) to
15 mph (25 km/h).

HDC is automatically deactivated once
vehicle speed again exceeds approx.
35 mph (60 km/h).

To switch the system on

Press the button. The indicator lamp
comes on.

The indicator lamp flashes when the
brakes are applied automatically.

To switch the system off

Press the button again; the indicator
lamp goes out.

HDC is deactivated automatically above
a road speed of approx. 35 mph
(60 km/h) and when the ignition is
switched off.

To use HDC

With manual transmission:
Use HDC in first gear and in Reverse
since the engine's braking effect is
diminished in the higher gears.

With automatic transmission:
You can use HDC in every drive
position.

In the event of a fault

The indicator lamp goes out in the HDC
mode or does not come on when HDC
is switched on:
HDC is temporarily not available if
brake temperature is too high.

If the DSC indicator lamp also
lights up:
There is a fault in the HDC and

DSC systems. Have your BMW Sports
Activity Vehicle center inspect this
system as soon as possible.
