What is it?
All Terrain Progress Control (ATPC) automatically maintains a set speed during off-road driving.
It maximises traction and allows the driver to concentrate on the terrain and the vehicle’s course.
What does it do?
ATPC acts as a low-speed cruise control for off-road driving. It provides the following benefits:
-
Automatically manages the engine output and the brakes.
-
Minimises any loss of traction and maintains the target speed the driver has set.
-
Allows the driver to focus on steering and assessing the terrain ahead, making off-road driving easier and safer.
What’s the difference between All Terrain Progress Control and the Terrain Response system?
All Terrain Progress Control is an off-road cruise control.
It maintains a steady, slow speed in tough off-road conditions.
It allows the driver to concentrate on steering and assessing hazards.
Terrain Response is a system which provides several driving modes.
Each mode tunes vehicle settings to ensure the best combination of traction and vehicle response for a particular terrain.
Both have the same goal.
They aim to make it easier and safer to utilise the exceptional capabilities of our vehicles, whatever the conditions.
When will you use it most?
It’s particularly useful in off-road conditions in which maintaining a consistent, low speed is important.
ATPC provides steady, controlled progress and limits wheelspin – ideal when ascending steep, slippery slopes or traversing rocky ground.
How do you activate it?
Press and release the ATPC button on the centre console.
You must close all the doors and fasten the driver’s seat belt before the system will engage.
When ATPC is in operation the button will light up, and there’s also a warning lamp on the dashboard.
What happens when you activate it?
If you activate ATPC when the vehicle is stationary, it automatically selects a descent control mode.
When you release the brakes, the vehicle starts to move.
ATPC will limit the speed to 2.2mph with the gearbox in high range.
In low range, it will limit to 1.1mph.
The driver can press the accelerator to temporarily override the system.
But as soon as the driver releases the pedal, ATPC will take over again.
When you activate ATPC while the vehicle is moving, the system activates the full function mode.
This happens at speeds between 2.2mph and 18.6mph.
The system then sets the current vehicle speed as the target speed.
How do you control ATPC?
The cruise control buttons on the steering wheel can be used to control ATPC.
The SET+ and – buttons will increase and decrease the target speed between 1mph – 18mph.
The CAN button engages the descent control mode.
RES resumes the target speed after the driver has used the brakes to slow the vehicle.
