Land Rover Defender: All terrain progress control (ATPC) safety
Make sure the following warnings have been read and fully understood before using All Terrain Progress Control (ATPC).
Failure to follow the guidance could result in vehicle damage, serious injury, or death.
Use extreme care when maneuvering the vehicle in challenging off-road conditions. The driver must maintain full control of the steering and be prepared to use the brakes at all times.
Do not attempt a steep descent if ATPC is not enabled, or if the instrument panel displays any warning lamps or messages.
Do not allow ATPC displays to distract the driver while the vehicle is moving.
ALL TERRAIN PROGRESS CONTROL (ATPC) OVERVIEW
Make sure the relevant safety warnings have been read and understood before using All Terrain Progress Control (ATPC).
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 maneuvering in a forward or reverse direction.
- Make progress and maintain a selected speed, up to a maximum of 19 mph (30 km/h).
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.
The instrument panel displays warning and information messages to make sure the full benefits of ATPC are realized.
Note: The cruise control, speed limiter, and auto stop/start systems are disabled when ATPC is operating.
