PRINCIPLE OF
OPERATION
HDC operates in conjunction with DSC to
provide greater control when off-road,
particularly when descending steep
slopes. HDC operation is fully automatic
when engaged.
During a hill descent when driving off-
road, engine braking is used to control the
speed of descent. If engine braking alone
is insufficient to control the vehicle's
speed, HDC will slow the vehicle using
the braking system.
If the vehicle is fitted with a manual
transmission, HDC should only be used in
first, or reverse gears. If the vehicle is
fitted with an automatic transmission,
HDC should only be used in
D
,
R
, or
Sport mode
1
. When in
D
the vehicle will
select the most appropriate gear.
