This is a question to 100 series Sahara owners:

These vehicles have two features that I don't quite understand. One is Active Height Control and the other is Toyota Electronically Modulated Suspension.

What do these do?

Is it likely that one or both will cause the vehicle to lower its suspension height if too much weight is put on board?

If yes, does this include towball weight from a caravan?

I will be looking at the prices of 100 series diesels about 6 months after the 200 comes out and if the answers to these questions dictates I may have to limit my gaze to VX models.

No Kev, the plan is to have the "truck" and an auto 100 for SWMBO.

I'm real serious about spending the kids' inheritance now.

Personally dont own one but I had one for three weeks as a work car when the Prado they gave me got mashed.

TEMS: electronically controlled shockies; set for comfort, normal, or sport I think the settings are. The adjustment will be located just in front of the gear selector.
Will have no effect on the height of the vechile just the level of softness in your ride.

AHC: rear airbags that you can adjust the height of for things like missus putting shopping in the back or pump up whilst offroad. will maintain set height until altered no matter how much stuff you put on the towbar or in the back. There is a button labelled 'Height control ON/OFF' that lets you turn this off for what ever reason........... cant think of why you would want to though and revert to whatever the stock ride height is.
Will maintain rear ride height regardless of load.


I dont think Mr Yota has been inporting the 100s for quite a while so if I was buying a Sahara 4.2 I would be getting my hands on one REAL REAL REAL quick or you may just miss out on one of the last 'real' landcruisers. I have seen runout deals in the weekend papers since April.

PS: 200 series looks like a bloated Kluger and is 'packed with electronic gizmos' yee hah......... thank christ the 4.8 Patrol still exists.

There are a few good 2nd hand ones coming up on Carpoint but still a bit exxy.

I reckon about 6 months after the 200 comes out will see some good prices coming through.

GB, I posted a link a couple of years ago to Kinetic the Western Australian company that was supplying new systems to the Citreon rally cars. At that stage Toyota had bought into the technology and these are the first big prodcution cars to fit it. Have a look to Kinetic and do some other Google searches too

I have this vehicle and found these features little more than a gimmick - the height controll is good unladen - you can dial up another 2 inches of height when off road - reverts to normal height when speed gets over 40. You can lower your height to get into a car park - again only under 40 - (you cant keep it low for highway handling). The whole system gives up with any serious load (5 metre aluminum tinny on trailer or a full car of blokes) and sags into the low setting - does not restore height with the caravan - too heavy. To enable this system to work the rear springs are very thin - hence the inability to carry a load. I was forced to remove the whole system and install heavy springs and polyairs for my van. The modulated suspension - put it on soft for more body roll - about the only effect.

cheers

Thanks Ross,

on another recent post someone was talking about their Prado doing the same thing, ie, sagging back to the low setting all by itself when it detected too much weight in it. I want to make sure that the 100 series setup is or is not the same. I suspect that it will be the same.

Still I may end up being memerised by the new 200 and blowing more than I intended.

In hindsight it did not cost much (relatively) to get the right suspension - about 1000 all up, and I still love the car - quiet, fuel efficient and very nice inside. Mechanically the GXL would have been a better option for towing though. The height adjustable suspension is regulated by hydraulics into the shock absorber body - once the load exceeds this pressure -it falls back to the springs which are not up to scratch for towing and it sags. I bought it thinking it would be just the thing for getting a level ride when towing - but only works unladen.

Another bit of feedback - offroad traction control is overated - a nice luxury at the snow when it activateds automatically when you weren't expecting to lose traction but useless on the beach and takes plenty of revs to work offroad properly. Have put in front and rear diffloacks - massive improvement in traction in the slippery stuff compared to traction control. Allows you to drive slow and steady accross the nasty stuff to protect the car.

I've got one of these too....it's either virtually unladen or towing either a boat or racecar and loaded to the gunnells. It will drop to lowest setting with a load on (I think I read somewhere a total of 340Kg or something including what is on the ball). I've installed Polyairs with the otherwise standard suspension and it's fixed the problem. Got a mate with a LX470 and works for him too.
