Is this a hypothetical question... because I don't believe you have the option of switching off TC on your 2011 Puma?
There have been a few threads discussing fitting switches or pulling fuses etc. edit to add In the last MY2015 with DSC, there is a switch to disable it, which the user guide advises might help with snow etc. I think turning off DSC also tones down the ETC (and *maybe* even the ABS a little??). For earlier models as far as I am aware, there is nothing you can do (as standard without a modification) to adjust the ETC setting? |

This works for me, thought it was a know thing!
"NOTE: TC can be disabled by operating the brake pedal ten times within ten seconds, when the ignition is turned on. TC will be re-activated when the ignition is turned off then on again." |

That does work, but I think it also disables the ABS as well. From memory when you do press the pedal ten times it illuminates the TC and ABS warning lights on the dashboard.
I think the issue the Jaguar driver had would be more to do with tyre size. Typically they (along with many other cars fitted with alloy wheels) have big fat tyres, which are great for cornering on tarmac. Sadly they are rubbish at cutting into snow to find grip so just "float" on the surface. 2007 - Stornoway Grey 90 XS SW - Gone 2002 - Black Discovery II - Gone 2014 - Montalcino Red 110 XS SW |

It's the first mention of it I recall 
As mentioned I have seen plenty of discussion about pulling fuses or adding switches etc. Is that from 2011 Owner Manual? Also I have no idea if that applies to later models as well? This is MY16 info from owners manual...  Click image to enlarge |

Which is good! You don't want ABS in the snow! |

In snow or mud a locked wheel will build up snow or mud in front of it stopping you substantially quicker than a moving sliding wheel..

Then ABS should be left on, a locked wheel does not steer the vehicle, and hence how ABS works in the snow. "Rafiki" 2007 110 STW - Rolling rebuild.

That's fine if you want to steer into a wall but if you want to stop before it I would rather not have ABS on.. Why would you want to steer if you are trying to stop? I have had many occasions where I have no need to steer, I just need to stop in a hurry!
I guess it's six of one and half a dozen of the other! At least without ABS you have the option. If you want to steer pump the brakes ( like we did in the old days) and if you want to stop hold them on hard! Last edited by Pinky on 14th Aug 2016 8:16pm. Edited 1 time in total |

22 years of driving in Norway winter, I have completely different experience in snow.
A vehicle with ABS will stop quicker then a non ABS vehicle given that solid pressure is held on the pedal. On mud I believe the same is true, but I do not have not enough experience to make a conclusion. I guess we see the world from different angles and experience´s.

I guess your right, I have had 40 years driving without ABS just altering brake pressure to suit the conditions.
This is my first vehicle with ABS and it's difficult to release control to a machine! It's a bit like the recent events with the tesla and its auto drive or whatever it's called.. I guess I'm just old school and drive using the feedback from the controls  |

ABS on, retain control of steering while braking as efficiently as possible.
TC on, brakes spinning wheel when grip is lost, rear axle only, to keep moving. Defender TC works differently to road car TC, which generally cuts power to stop spinning wheel. DSC off, when in deep mud or snow. If DSC is fitted. The only reason for switching DSC off is that it can cut power and brake wheels when you actually need a bit of wheel spin to keep moving, or are already stuck. These systems are set up to work in an all terrain vehicle, on all types of surfaces, trust them to do their job. |
