Low speed control
The low speed control function (LSC
tates and improves traction for driving off-
road and on slippery surfaces, such as with a
caravan on grass or a boat trailer on a launch
ramp.
The function is included in drive mode
Road
.
The function is adapted for off-road driving
and driving with a trailer at low speed, up to
approx. 40 km/h (25 mph).
With low-speed control, low gears and all-
wheel drive are prioritised, which help to avoid
wheelspin and provides better traction on all
wheels. The accelerator pedal is less respon-
sive in order to facilitate traction and speed
control at low speed.
The function is activated together with hill
12
descent control, (HDC ) which means that
speed down steep hills can be controlled with
the accelerator pedal, reducing the need to
use the brake pedal. The system facilitates a
low and even speed while driving on steep
downhill gradients.
