In this blog post, we'll take a deeper look at how Terrain Response 2 works and why it's an invaluable asset for off-road driving. Understanding the capabilities of this advanced system will give you the knowledge to get the most out of your Range Rover on your next adventure off the beaten path.
What is Terrain Response 2?
Terrain Response 2 was launched on the Range Rover in 2013. It keeps the manual modes of the original Terrain Response system, each of which sets up the engine, gearbox, differentials, suspension and traction control for a particular surface, and adds an Auto mode that reads the conditions and chooses the setting for you.
Similarities and Differences from Terrain Response
Like the original Terrain Response, Terrain Response 2 offers specialised driving modes for surfaces like snow, sand, mud, and rocks. Both systems aim to optimise vehicle control and traction by coordinating various systems.
The defining difference is Auto mode. With the original system the driver had to pick the right mode for the surface. Terrain Response 2 monitors how the wheels, suspension and traction systems are behaving and switches to the most suitable mode itself, and the driver can still override it with a manual selection when they know what the ground ahead is like.
Multiple Driving Modes
Terrain Response 2 includes preset modes for:
- Auto, which reads the surface and selects the most suitable of the modes below
- Normal driving
- Grass, gravel, or snow
- Mud and ruts
- Sand
- Rocks
Each mode is specially calibrated for maximum traction and control on its respective surface. For example, the sand mode allows more wheel spin to prevent the vehicle from becoming stuck.
Adjustable Vehicle Systems
Terrain Response 2 can modify settings for:
- Brakes: Adjusts brake pressure and pedal sensitivity
- Engine: Controls throttle response and torque output
- Transmission: Selects appropriate gears for the conditions
- Traction control: Manages wheel slip within safe limits
By coordinating all these systems simultaneously, Terrain Response 2 optimises vehicle mobility and handling over any terrain.
Why is Terrain Response 2 important for off-roading?
The Range Rover is built for this kind of driving. Its air suspension can raise the body for extra ground clearance, and Terrain Response 2 ties that suspension together with the engine, gearbox and traction systems so they work as one.
Terrain Response 2 enhances the Range Rover's inherent off-road abilities even further. This innovative system allows drivers to optimise the vehicle's settings for different surfaces like grass, sand, mud, rocks, and snow. With the turn of a dial, Terrain Response 2 adjusts the traction control, suspension, transmission, and more to suit the environment.
Maximising Grip and Control
By coordinating these various systems, Terrain Response 2 maximises the Range Rover's grip and control off-road. For example, in mud and ruts, it raises the ride height while allowing more wheel slip to maintain momentum. On loose surfaces like gravel, it keeps wheels from digging in too deep. This results in improved handling no matter the terrain.
Enhancing Safety
In hazardous off-road situations, Terrain Response 2 also enhances occupant safety. Features like Roll Stability Control and Hill Descent Control prevent dangerous loss of stability when tackling steep inclines or side slopes. The system even adjusts throttle response and gear selection to make low-speed off-roading less demanding.
With Terrain Response 2 expanding the Range Rover's off-road talents, drivers can explore remote locations with greater confidence and control.
How does Terrain Response 2 work?
The Terrain Response 2 system builds upon the capabilities of the original Terrain Response system. At its core, Terrain Response 2 integrates various vehicle subsystems to provide enhanced drivability and control across different terrains and conditions.
Components of the Terrain Response System
The key components of the Terrain Response system include:
- Drive Mode Selector: Allows the driver to choose from different drive modes optimised for different conditions like grass/gravel/snow, mud and ruts, sand, and rock crawl.
- Terrain Response Control Module: This module controls and integrates settings across the drivetrain, chassis, and safety systems when a drive mode is selected.
- All Terrain Progress Control (ATPC): Helps maintain a steady low speed over challenging terrains.
Integration with Vehicle Subsystems
Building on these core components, Terrain Response 2 goes a step further by integrating with various advanced driver assistance systems:
- Adaptive Dynamics: Adjusts suspension dampers to suit the terrain.
- Dynamic Stability Control: Maximises traction and stability specific to the selected drive mode.
- Electric Power Assisted Steering: Alters steering feel and response for each drive mode.
Benefits of Terrain Response 2
By controlling all major subsystems simultaneously, Terrain Response 2 offers these advantages:
- Enhanced off-road capabilities to tackle more challenging terrains.
- Better vehicle control and drivability through optimised settings.
- Increased safety by maximising traction and minimising loss of control.
With Terrain Response 2 coordinating the air suspension, drivetrain and traction systems, the Range Rover is as capable off the road as it is comfortable on it.
When Terrain Response 2 Reports a Fault
If the display says Terrain Response is unavailable, or a selected mode will not engage, the selector is rarely the root cause. Terrain Response 2 depends on the air suspension, the traction and stability control and the transmission, so a fault in any of those systems, or even low battery voltage, can take it offline. The useful first step is to read the fault codes from all of those systems rather than the Terrain Response controller alone.
We diagnose these faults as part of our Range Rover specialist work at our Worthing garage.
Conclusion
After exploring the capabilities of Range Rover's Terrain Response 2 system, it's clear this technology takes off-roading to the next level. By intelligently monitoring driving conditions and automatically adjusting the vehicle's systems to suit the surface, Terrain Response 2 gives drivers enhanced control and confidence on rough terrain.
Some key takeaways:
- Terrain Response 2 builds on the original Terrain Response system by integrating more vehicle systems for a more comprehensive response
- Multiple traction and stability control modes adapt to surfaces like snow, sand, mud, ruts, and rocks
- Advanced technologies like Wade Sensing and All Terrain Progress Control further improve off-road prowess
- Drivers can manually select modes or let the system detect conditions and optimise settings automatically
With Auto mode doing the thinking on mixed ground, and manual modes for when you know what lies ahead, Terrain Response 2 is one of the main reasons the Range Rover is so capable away from the tarmac.
Range Rover Terrain Response 2 FAQs
What is the difference between Terrain Response and Terrain Response 2?
Terrain Response 2, launched on the Range Rover in 2013, keeps the manual modes of the original system and adds an Auto mode that detects the surface and selects the most suitable setting for you. With the original system the driver always chose the mode.
What does Auto mode do in Terrain Response 2?
Auto mode monitors how the wheels, suspension and traction systems are behaving and switches between the terrain settings on its own, adjusting the suspension, differentials, throttle and gearbox to suit. You can override it at any time by selecting a mode manually.
What are the Terrain Response 2 modes?
Alongside Auto, there are manual modes for general driving, grass, gravel and snow, mud and ruts, sand, and rock crawl. Each sets up the engine, gearbox, suspension and traction control for that surface.
Should I leave Terrain Response 2 in Auto?
For most driving, Auto is the sensible setting. Selecting a manual mode is worth it when you know what is coming, for example choosing sand before driving onto a beach, so the car is set up before it needs to be.
Why does my Range Rover say Terrain Response is unavailable?
Terrain Response 2 relies on the air suspension, traction control and transmission, so a fault in any of them, or low battery voltage, can disable it. The cause is usually in one of those systems rather than the selector, so the fault codes from all of them need reading.
Can Stedmans Garage diagnose Range Rover Terrain Response faults?
Yes. We work on Range Rovers at our Worthing garage and can read the fault codes from the suspension, traction and transmission systems to find out why Terrain Response is not working before any parts are ordered.
