Volvo XC90 TWIN ENGINE Owner's Manual page 469

The driver can brake and reduce crawling speed,
or stop the car at any time by using the foot
brake.
The function is activated together with Low
Speed Control (LSC) which facilitates driving and
improves traction for driving off-road and on slip-
pery surfaces. The systems are designed for use
at low speed, up to approx. 40 km/h (25 mph).
Points to remember when driving with
HDC
•
If the function is disabled while driving on a
steep downhill gradient, the braking effect
will gradually decrease.
•
HDC can be used in gear position D, R, and
with 1st or 2nd gear with manual gear
changing.
•
It is not possible to change to 3rd gear or
higher with manual gear changing.
NOTE
When LSC with HDC is activated by the OFF
ROAD driving mode, the feel of the accelera-
tor pedal and engine response are changed.
NOTE
The driving mode is not designed to be used
on public roads.
NOTE
The function is deactivated when driving at
higher speeds and must be reactivated at a
lower speed, if required.
