Changing Tire with Quadra-Lift
 
Eons ago I used to drive a very weird Citroen DS with air-oil suspension; you know, the one that looked like a cockroach from Mars. Like the QL, the vehicle could be raised or lowered by the driver. Part of this setup included being able to set the drop to a special ultra-maximum to aid in changing flat tires.

This allowed a simple rod to be attached to one of four connection points on the chassis, then the driver could move the QL-type control to max drop and the wheel would rise until it was an inch or so above the ground, while the car itself was held up by the rod.

So no jack was needed to change a flat -- just slip on a rod, move the control to max drop, then loosen the lug nuts. At the end, reverse the procedure. Quick, super-easy and no jack needed.

Can the QL do anything like this?

I also thought about this, but it seems too convenient. There must be a catch.
In theory it could also be used to get out of a sticky situation, like sand maybe? :confused:

You are supposed to disable QL before changing a tire by holding the "up and down" buttons at the same time for 5-10 seconds. Driving over 5mph will re-enable QL.

My manual states to disable the Qaudra-lift for jacking and changing the tire. You do so by pressing and holding the up and down buttons simultaneously for several seconds. The system will return to normal when the car is driven above 15mph.

I am not well known for doing what I am "supposed to" though

Thanks for the feedback. You have to wonder whether Chrysler/Mercedes even considered using QL to facilitate tire changes when they were designing it. That Citroen was an oldie, ca. 1959, so perhaps by now this feature has been long forgotten, 'cuz I haven't heard of it being on anything recent, such as Land/Range Rovers.

I've only driven the original version, the 1959 model. Inboard magnesium brakes and that air-oil suspension made it damn near a Ferrari when I took it for suicide laps on narrow Spanish mountain roads. But QA was dreadful, the engine a flathead (!!), the dash-mounted stick shift used a centrifugal clutch that worked horribly, and the brake "pedal" was a button the size of a quarter that went from freewheeling to thru-the-windshield stop in 1/8" -- had to drive it in stocking feet to have any control over braking force.

What they're like now, I have no idea. One DS was enough to swear me off them for a lifetime, even with its phenomenal braking and high-g grip.

I would think that it cannot be done due to the fact that the syste works on preasuring the air. In order to lift one wheel you would need to create a vacuum so the wheel would lift. I do not see that happenig with our system. Just be glad that it goes up and down lol
