Make sure the relevant safety warnings have been read and understood before using All Terrain Progress Control (ATPC). See ALL TERRAIN PROGRESS CONTROL (ATPC) SAFETY.

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:

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. See TERRAIN RESPONSE OPERATION.

The instrument panel displays warning and information messages to make sure the full benefits of ATPC are realised.


The cruise control, speed limiter, and auto stop/start systems are disabled when ATPC is operating.
