So had my LS460 on jacks for better of a week, doing the laundry list of maintenance items. When I completed my work and went to take it down off the jack stands, the car went all the way to the ground and pinned my jack. Scared the hell out of me. Luckily, my neighbor was home and had another low profile jack to get under a side and lift it to remove the jack. So at this point, I am racking my brain to think what I did wrong. Then all I could think of is that the car has air suspension and maybe they were the plaintiff. Started the car and waited, slowly but surely, the car came back up to normal height. Whew!

I'm hoping someone can save me from screwing this up next time it has to go on jacks, by telling me what I did wrong or need to do.

Thanks

The owners manual says to turn off the height control before raising the vehicle - page 494 of the online owners manual at https://drivers.lexus.com/t3Portal/d...f/OM50738U.pdf

So I missed that one, thanks. So read the manual and does not say "How" to turn it off. Is it simply pressing the High Height button and leaving it on?

yea the air struts "air out" all the time when you jack the car, at least mine do

So how do you turn off the height control?

i think they mean set height to normal or turn height high off.

It just means make sure the height high button is switched off and don't start the car while it is on the jack stand because the suspension will try to correct the height of the wheels when they are hanging. This is why the car went to the ground once you removed the stands.

That’s the problem. You have to start the car on jacks when doing transmission fluid changes, in order to get to the right temp. The time it takes to jack the vehicle and get it level, once it reaches the right temp is too time consuming
