Scratch head (Gen 4 Owner manual) was created by Andy2640
Morning all,

On page 3-16, the topic is "changing from 2H to 4H" - Its states "Do not shift the transfer lever without depressing the accelerator pedal" EHH????

It also goes on to say that the locking air hubs cannot be activated if the vehicle is slowing down, but then says it can be done at standstill. EHH?

Any help would be appreciated.

The first part, I would assume, is a misprint, Andy. Surely, it should read brake pedal?:huh:


Where are you seeing this?:

"It also goes on to say that the locking air hubs cannot be activated if the vehicle is slowing down, but then says it can be done at standstill."


Full marks to you for reading the manual, by the way. :laugh:

Hhaha, thanks Steve. All this is on page - 3-16.

It makes me laugh, because next to most this 4H to 4L thing, there are warnings saying "FAILURE TO FOLLOW WILL RESULT IN SERIOUS MALFUNCTION" Intimidating bloody manual so it is ;-)

Ok, the manual actually says this; " The air locking hubs are activated by the vacuum of the engine and changed to shift the front wheel drive. The air locking hubs are not shifted when the engine is stopping" / - So are they saying that decelerating will not activate the air hubs? Hence there instruction to be accelerating??

Mhhhhhh Pondering's..........

Ah! Now, I read that as saying that the engine needs to be running for the air hubs to operate.

I think that it should read "The air locking hubs are not shifted when the engine is stopped"

I think it means that the engine has to be running to generate the vacuum. So it won't activate the hubs when switched off. I would also expect that charging between ratios is done while stationary and the brake applied and clutch down. But it should be able to switch from 4x2 and 4x4 high on the move.

The translation of the manual is quite good, but I noticed it get worse further on.

Mhhhh, thanks for the perspectives, this is a funny one tho hay? "Do not shift the transfer lever without depressing the accelerator pedal"

It says nothing about depressing the clutc when switching from 2H/4H/4L??

That could have changed but on the gen3 it's a thing.

So is the consensus, that we should depress the clutch when switching from all transfer modes?

EDIT: Better safe than sorry I suppose.

I would. Like you say being cautious is not a bad thing.

I follow your wise and mystical giuidance Lord Lambert :-) On another note, to my monkey mechanic mind, "air hubs" sound like something that could go very wrong, very easily. Hope I am wrong though...ekk!

Mine didn't make it to year 4. Since then I have had avm manual ones. Bit more effort but way more reliable and versatile. They allow me to run on the road in 4x2lo which is great for towing and manoeuvring trailers. It is possible to do this electronically on the gen3 as well as mechanically so I suspect that it is a modification in development for the gen4.
