Terrain Response

Last updated: 18 June 2012

Terrain Response is Land Rover's clever off-road system: a single rotary dial with pictograms that, in one twist, reconfigures throttle response, ride height, gearbox behaviour, ABS and differential settings to suit the surface. It arrived on the L322 with the 2006-2007 update, shared with the Range Rover Sport and Discovery 3.

Key takeaway: One dial, five modes — Terrain Response retunes throttle, gearbox, height, ABS and diffs for the surface. Arrived in 2006.

The five modes

Mode	For
General driving	Normal on-road use; balanced settings
Grass / gravel / snow	Slippery surfaces; gentle throttle, early traction help
Mud & ruts	Soft, uneven ground; maintains momentum, raises height
Sand	Loose sand; keeps revs up, reduces drag
Rock crawl	Low-speed technical terrain; max height, fine control

What it actually controls

Choosing a mode adjusts several systems together, so the driver doesn't have to:

Throttle response — gentler on slippery surfaces, sharper where needed
Ride height: raises the air suspension for rough terrain
Gearbox shift pattern — holds gears appropriately
ABS calibration. Brake-force distribution suited to the surface?On loose surfaces a little wheel lock can actually help braking by building a wedge of material ahead of the tyre, so Terrain Response alters the ABS behaviour by mode.
Differential / traction control: lock rates and intervention

It works alongside Hill Descent Control and the two-speed transfer case (low range) for serious off-roading.

When it arrived

Terrain Response was not on the 2002-2005 BMW-era cars. It came in with the 2006/2007 update, part of the same package that brought the new dashboard, electronic parking brake and Brembo?Brembo — Premium Italian brake maker; larger discs and multi-piston fixed calipers give stronger, more fade-resistant braking on heavy/fast cars. brakes. If a car has the rotary Terrain Response dial on the centre console, it is a post-facelift car.

Ownership notes

TIP Even if you never go off-road, exercise low range and any diff lock once or twice a year — it stops the actuator motors sticking. The same applies to using the various Terrain Response modes occasionally.

The system itself is reasonably reliable; most related warnings trace back to ageing height or chassis sensors rather than the Terrain Response electronics.
