STARTING AND DRIVING
* Option/accessory. 390
Auto-hold brake function
With the Auto-hold brake function, the driver can
release the brake pedal and the brakes will
remain applied, for example, when the vehicle
has stopped at a traffic light or intersection.
When the vehicle is no longer moving forward,
Auto-hold applies the brakes automatically, either
using the normal brakes or the parking brake.
The brakes will be released when the accelerator
pedal is depressed.
If the driver's door is opened or the engine is
turned off, the parking brake will be applied auto-
matically.
Auto-hold is deactivated when the transmission is
in neutral or if the driver's door is open and the
seat belt is unbuckled.

ing backwards when starting up a hill.

Low Speed Control (LSC)
*
8
Low Speed Control (LSC) helps make off-road
driving easier on slippery surfaces when towing
a trailer on grass, etc. This feature is part of the
Off Road
drive mode.
When driving at low speeds, LSC prioritizes low
gears and all wheel drive to help avoid wheel
spin and to improve traction on slippery surfa-
ces. The accelerator pedal and engine react dif-
ferently to make low-speed driving easier.
In models equipped with the drive mode control
*
,
LSC is part of the
Off Road
drive mode.
It is activated along with Hill Descent Control
(HDC), which increases engine braking to help
keep vehicle speed low and smooth, even driving
down steep hills.
Activating LSC
This function can be activated in different ways,
depending on how the vehicle is equipped.
