Re: New michelin Latitudes
Pushing both buttons will disable QL (confirmed by a message on the EVIC screen). The Jeep stays at normal ride height in my experience.
If taking it in to a non-Jeep dealer, best to remind them about this procedure, in case they need to do work after a test drive. e.g. Text from page 368 from the Owner's Manual, 5th ed.:
"To assist with changing a spare tire, the Quadra-LiftTM air suspension system has a feature which allows the automatic leveling to be disabled. Press and hold both the “Up” and “Down” buttons simultaneously between 5 and 10 seconds, a message will appear in the EVIC stating leveling has been disabled immediately after both buttons have been released. Refer to “Electronic Vehicle Informa- tion Center (EVIC)” in “Understanding Your Instrument Panel” for further information. Driving the vehicle over 5 mph (8 km/h) will return the air suspension to normal operation."
