Activation - Advanced Off-Road Capability Pack
** ONLY AVAILABLE FOR INSTALLATION AT VULKAN HQ **
This activation bundle contains the following specific unlocks/upgrades:
- All Terrain Progress Control (ATPC)
- Terrain Response 2
- Configurable Terrain Response
Our activation process uses genuine Land Rover tools and systems to quickly and safely unlock the hidden features of your vehicle. These software upgrades use the existing hardware already installed in your Defender and do not require any physical modifications to the vehicle.
All Terrain Progress Control
ATPC is an aid to off-road driving. When activated, the system attempts to maintain a constant vehicle speed when met with challenging off-road conditions. For example, when traversing snow, grass, gravel, sand, or mud.
Two levels of ATPC are available:
- Descent control mode.
- Full function mode.
When ATPC is enabled, and the brake pedal is fully released, the system helps to provide controlled and progressive assistance to allow the vehicle to:
- Pull away from a standstill, in a forward or reverse direction, on level ground, uphill, or downhill.
- Perform low speed manoeuvring in a forward or reverse direction.
- Make progress and maintain a selected speed, up to a maximum of 30 km/h (19 mph).
ATPC also works in conjunction with the terrain response system, and applies different acceleration rates based on the selected driving program. For example, the grass gravel snow setting requires the ATPC system to apply gentle vehicle acceleration. The comfort setting requires the ATPC system to apply a greater rate of vehicle acceleration.
Terrain Response 2
Terrain response comprises a number of different driving programs that can be selected to suit the current terrain, driving conditions, or driving style.
Each driving program alters various vehicle settings, including suspension height, engine speed, and the amount of steering effort required.
Terrain response works in conjunction with the Hill Descent Control (HDC) and Dynamic Stability Control (DSC) systems to further enhance the vehicle’s capabilities.
Terrain Response 2 adds the AUTO program to the existing options; this terrain response setting automatically selects the most appropriate driving program for the prevailing conditions.
Configurable Terrain Response
The configurable terrain response feature allows the user to create a unique off-road terrain response profile. Up to four profiles can be created.
A unique terrain response profile can be selected in the same way as a standard terrain response driving program. The last used profile is automatically selected.
