Terrain Response 2 AUTO + ATPC for Land Rover
This Terrain Response 2 AUTO system with ATPC adds automatic terrain detection and low-speed off-road cruise control. Direct-fit JLR retrofit with full configuration support.
Factory-Grade Terrain Management
The Terrain Response 2 AUTO system with All Terrain Progress Control gives your Land Rover intelligent off-road capability. You select the AUTO mode through the rotary controller or touchscreen, and the system continuously reads steering angle, throttle position, wheel slip, and suspension data to identify the surface beneath the wheels.
The system then adjusts engine response, gearbox shift points, centre differential locking, and rear differential settings to match the conditions. You no longer need to choose between grass, gravel, snow, mud, or sand modes manually. The vehicle adapts automatically as you move from tarmac to loose surfaces and back again.
ATPC operates like low-speed cruise control for off-road driving. You set a target speed, and the vehicle maintains that speed while climbing, descending, and crossing uneven ground. The system applies individual wheel braking and engine torque as required, so you concentrate fully on steering and route selection. You gain smoother progress on steep descents, slippery ascents, and rutted tracks.

Frequently Asked Questions
What difference does ATPC make on rough terrain?
ATPC maintains your chosen speed automatically, so you avoid wheel spin and sudden lurches. You steer while the system manages throttle and braking for smooth, controlled progress.
Will this system work with my existing suspension and drivetrain?
Yes. LR-Retrofit verifies your vehicle configuration and supplies the correct module variant. The system integrates with your existing air suspension, locking differentials, and stability control.
Do I need coding after installation?
Most vehicles require configuration to activate the AUTO mode and ATPC functions. LR-Retrofit provides remote configuration support, or you can arrange a workshop visit if preferred.
