Default New to me QX, rear suspension question

New to me 2013 QX

When I 1st start the QX should I hear the compressor run to bring the rear up? it seems to be sagging. Or will it only compensate when I haul heavy loads or a trailer?

Thanks

its in the operator's manual in how this operates,

but the compressor runs to keep the rear end level. it will do this if the sensor in back detects the rear end is below normal ride height. the compressor can come on in the cold or if there is a load.

to determine if your compressor works as it should:

open the rear door. put some weight on the end of the trunk. so get 3 adults or comparable weight and sit it on the end there.

wait a couple minutes

turn the car on

compressor should kick in to raise the rear height if the weight is substantial enough to lower the rear end.

mine runs every time i start, and some other times -- when it is cold. The seals where the tubes go from the compressor to the shock shrink up or harden and air escapes. Doesn't happen when it's say above 50 degrees. It's really annoying. i bought some flexible pipe sealer (PFT or something like that) based on some recommendations in threads about armadas and will give that a go this summer when i have time.

it takes about 20-30 seconds after start to kick on.

Hello,

I searched and could not find a thread with some introductions on how to properly adjust the ride height sensor. Does anyone have any experience with this? Any help will be appreciated.

You can find the service manual online for your model (its free). You can get the info you need there.
