Terrain Response on new 4x4’s

[Mike Nel]

Could someone please explain how this works?

I take the 200 Cruiser as an example and there are other vehicles with the same function.
Functions would be:

-Snow and Ice
-Sand
-Mud
-Rock and gravel

I have always been taught that you turn off all Nanny Aids when driving in the sand because you don’t want the Traction Control System to interfere.

So who here can explain what happens in the above mentioned senarios when the funtion for it is chosen?

The Amarok is the best 4x4xfar because of the Traction Control

-Snow and Ice
-Sand
-Mud
-Rock and gravel

I’ll have a go. Naturally these differ depending on which manufacturer programmed them, usually involving different settings for engine, transmission & diffs/traction control.

Off the top of my head:

- Snow and Ice
Short gear-changes, longer throttle pedal (less responsive), fairly aggressive TC

-Sand
More responsive pedal, Engine power at its max, faster gear changes. TC less aggressive. Center locked.

- Mud
Centre & Difflock on, TC not as aggressive, Longer pedal, reduced gearing

- Rock (and gravel)
All lockers come on quicker, Longer pedal, very low gearing, very aggressive TC.

Although I would think that gravel should be a very different program.

Agree with the above.

On the bold above.

On the Disco's we also turn off stability control. For some makes the guys pull the fuse.

The only place I’d leave Stability Control on, is gravel. But only with the centre free.

In all other offroad instances if should be off.

Too in the Navara, I turn off the SC when driving in deep loose sand. Otherwise the computer recognizes the slightest wheel spin as an accident waiting to happen.

Mud much the same, but low range is a must with the diff locked.

Never driven on snow before

For gravel it stays on for soft sand, we try turn as many aids off as possible.

On a D3 the center locks in low range, you can have a broken side shaft and drive it.
