4x4 mode speed limits?

Just wanted some information on whether the 4x4 mode has a speed limit? Does it only work on speeds under 30 kmph?

Also, if you have the 4x4 mode switched on, and drive faster than, lets say, 30kmph, does it adversely affect the drive train and other associated mechanics?

Aain, i would like to understand how the 4x4 mode works on the Yeti. Unless I switch it on, the car is rear driver or front? Its obviously not a full time 4x4?

Lastly, if you have a very long stretch of smooth but extremely wet road, would traction control help the car?

(Apologies if the questins a basic. Am a newbie in this space)

Firstly, there is no switchable four wheel drive ie no button. It's an automatic system allowing 5-10% to go to the rear axel at all times then varied as required. There is no speed limit for the haldex 4wd system, it works through town and at autobahn speeds. Haldex 4 is pre emptive also.

This might help:

I would also suggest that you look in the Handbook, as there is a very good description there about what it includes and how to use it.

If you look up "Haldex" in Wikipedia it gives a pretty good explanation of how it works (the Yeti has Haldex IV). You can also go on to Haldex's own web site and see funky videos illustrating it.

The Off-Road button tweaks the way some of the clever traction and stability control systems work, in order to help when driving over loose surfaces. It doesn't switch the 4x4 on or off. As proof: in the UK the Off-Road button is a factory-fit optional extra on all 4x4 models bar the Elegance spec. SO you don't need the Off-Road button to have 4x4.

This - and it also changes the way the throttle responds and engages the hill descent mode.

I could be wrong, but I think the first post is refering to "4x4 mode" and meaning Off Road Button.

So, for example, does the Off Road Button have a speed limit? etc...

...its something like 20mph from memory and the smart thing is that its then automatically comes back in when you drop back below the speed limit of its function. :)

I think the OP was under the impression that the Off-Road button was a 4x4 selection control like you get on some more traditional/old-fashioned 4x4 systems. These sometimes need the vehicle to be stationary before you can engage four-wheel drive, and sometimes have a limit on speed at which they should be used (usually I think because of limitations in the design of the mechanicals of the system eg differentials, or absence thereof).

...its something like 20mph from memory and the smart thing is that its then automatically comes back in when you drop back below the speed limit of its function.

It's not as cut and dried as that. The Off-Road button activates a number of different features which operate in different ways. You're probably thinking of the Downhill Drive Support function, which the handbook states operates up to 30kph (amongst other criteria). There's also the Off-Road ABS function which operates up to 50kph (at higher speeds you get normal ABS, rather than none!) Start-Off Assist, as the name implies, operates when you're starting off. TCS aka ASR Off-Road "operates when starting off or at low speeds" - there's no specific limit given. Similarly vaguely, "EDL is activated earlier in the Off-road mode than in the normal mode."

All this information is in the handbook.

Downhill Drive Support is really clever: the car doesn't even need to be in gear, and it works in reverse as well!

BossFox is right. And i got my answers from all the wonderful replies. I had read the manual, but the service guy was giving me a different story. (Skoda India service has a rather sad reputation). The sevice guy told me if I drove at high speeds with the 4x4 button switched on, i could risk damaging the car. But again, he seemed a little unsure himself. So i thought I should get this checked. Considering that fact that the Yetis has a very refined and modern tech driving it, i didnt thing this should be the case.

But then again, its always better to ask. Ad thanks for all the replies.

As I understand it the Haldex as fitted to the Yeti is developed from the system that was fitted to the Audi Quatro and that was rallied with no speed restrictions.

Not so sure on that, Audi generally used a longitudinal engine layout and Torsen diffs. Permanent 4wd, rather than the partial one using the Haldex system of the Yeti. Some of the later cars have started to use the Haldex system.

Two different systems but Audi do occasionally use a haldex setup (A3,S3,TT) but badge it 'Quattro')!

It's "quattro" with a lower-case "q" - the upper-case initial being reserved for the Audi Quattro car.

Audi badge anything with four-wheel drive capability "quattro" these days. It's their trade mark so I suppose they can use it how they like, but they did seem to be rather denigrating their own technical and sporting heritage when they suggested that the original, almost revolutionary torsen-based system from the fire-breathing Audi Quattro which dominated world rallying in the early eighties was "invented for" the rather flabby Q7 soft-roader (which actually uses a different 4WD system bought in from Borg-Warner anyway).

      Hi there, hoping someone on here will put this motor to good use. It has been stood for about 5 months and I have let the mot lapse. Tried starting it but the starter motor has died - the copper wiring on the top has perished. It was working fine prior to it being stood, well after I had replaced a suspension arm. It is being stored on my Mother in laws farm in High Legh, Cheshire approx 5 minutes from Junction 20 of the M6. 
       
      I really don't want to scrap this wolf in sheeps clothing and the engine and the interior has plenty of life left in her. I think it will be a fairly simple bit of work, however I have three other vehicles and have just bought a caravan so my storage quota is on the verge of getting me kicked out of the family. Speed is of the essence here so any sensible offer around £200 and a commitment to collect very soon gets you the motor.
       
      It has a great interior, there are a couple of marks commensurate with its age  and a rust spot coming through, but if you want it for the work horse it is or just for the vag engine alone its worth a punt. Has 6 cd changer and alloys.
       
      Buyer collects - you will need a trailer - it is a non runner and a 4x4, but we have a manitou to lift it onto a trailer. 
       
      Thanks for looking and very best wishes

      Can't find a retractable parcel shelf for a octavia mk2 combi online anywhere, it's a 2006 model pre face-lift.

      Hello,
      at the moment i am still 'superb wanabe', nevertheless i am very close to give away my savings. I am looking at Superb L&K tdi 110kw 6-dsg. And i have some questions. First about independent car heating. Is it possible to upgrade the sistem to activate it with the phone? As i am aware original remote control unit should be able to communicate with the car up to 1000m, but i am not sure if this is still possible with car parked lets say in a public garage and you are 500m away? Any experience?
      How about the sunroof? Should i order it or not? My bigest concern is additional noise due extra seals on the roof (noise at higher speed while the sunroof is closed). 
      Also, is it possible to open the roof in the way that only the last part gets lifted?
      If there is someone with the same engine/DSG and extra time, i would be gratefull for photos of instruments with speed and engine rpm at different speeds from 90 to 140km/h (10km/h increment).
       
      Hope i am not asking too much. Thank you for your answers and photos in advance.
       
      I've attached photos of instruments from my P307sw, 100kw, 2.0hdi, manual. I am quite interested to see comparison with Superb.
      There is no photoshop involved at any photo (500.000km are all mine!)

      Anyone have a mk1 Octavia estate for sale, either vrs or 4x4 1.8t? Preferably a later model (04/05) or an earlier one with low miles. I'm in Essex so around the south east is best but I'm willing to travel for the right car.
