Activating system
Press the button; the indicator lamp comes on.
The indicator lamp flashes when the brakes are
applied automatically.
Deactivating system
Press the button again; the indicator lamp goes
out.
HDC is deactivated immediately above approx.
35 mph/60 km/h and after approx. 10 seconds
when the ignition is switched off.
Using HDC
In vehicles with manual transmission:
Use HDC in first gear and in reverse gear, as in
the higher gears the engine's braking action
diminishes.
On vehicles with automatic transmission:
You can use HDC in every drive position.
Malfunction
If the indicator lamp in the button goes out in the
HDC mode or fails to light up when the button is
pressed:
HDC is temporarily not available, as the brake
temperature is too high.
Malfunction in vehicle stability control
systems
The warning lamp lights up yellow.
DBC Dynamic Brake Control is defec-
tive. Have the system checked as soon
as possible.
Display of the previously described
malfunction on Canadian models.
If one of the malfunctions described
below occurs, proceed cautiously and
defensively. When driving on poor roads, avoid
using the full throttle or kick-down positions of
the accelerator as well as heavy and panic brak-
ing. Otherwise the drive train may be damaged
or accidents can occur.
<
The red brake warning lamp lights up
together with the warning lamps for
ABS and DSC/xDrive. In addition, a
warning signal sounds. ABS, DSC,
HDC and xDrive have failed. Drive may
then only be carried out via the rear
axle. If the brake warning lamp lights up
yellow in the described combination,
the EBV Electronic brake-force distribution is
still available. Have the system checked as soon
as possible.
Display of the previously described
malfunction on Canadian models.
The warning lamp lights up continu-
ously and a warning signal sounds:
DSC or the xDrive all-wheel system has
failed.
The stabilizing interventions of DSC or the all-
wheel drive system xDrive are no longer avail-
able. It is then possible to exert driving force
only via the rear axle. Have the system checked
as soon as possible.
Flat Tire Monitor
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the four mounted tires as you
drive. The system provides an alert whenever
the inflation pressure drops significantly in rela-
tion to the pressure in another tire.
