STARTING AND DRIVING
* Option/accessory. 392
HDC is activated along with Low Speed Control
(LSC), which together make driving on slippery
surfaces at low speeds easier.
When HDC and LSC are activated, this changes
the response from the accelerator pedal and
engine.
Activating HDC
This function can be activated in different ways,
depending on how the vehicle is equipped.
Using the drive mode control
*
Select the

function.
Select a different drive mode to turn HDC off. If
this is done while the vehicle is on a steep down-
grade, engine braking will decrease gradually.

ton illuminates when the function is acti-
vated.
