2014 Overland Quadra Lift

Hello all,

On my 3rd day of having my 2014 Overland. Getting used to the Quadra-Lift system. Does driving while the jeep is adjusting cause any issues?

Example: I put the jeep in entry/exit mode.We have dinner and get back in. Do I have to bring the car back up to normal or can I just get in and drive off.

Example: When the yellow writing of "Lowering" or "Raising" is flashing, can I drive? If so do I need to limit my speeds?


Thank in advance to anyone who responds.

It's pretty much automatic. The only time I use the buttons is to put in park/exit mode, and to lift to OR1 or 2 to go off-road. It will even go to aero for highway driving automatically. I can't see why there would be any speed issues.

Info from the 2014 WK owner manual:

QUADRA-LIFT™
Description
The Quadra-Lift™ air suspension system provides full
time load leveling capability along with the benefit of
vehicle height adjustment by the push of a button.
• Normal Ride Height (NRH) – This is the standard
position of the suspension and is meant for normal
driving.
• Off-Road 1 (OR1) (Raises the vehicle approximately
1.3 in (33 mm) – This is the primary position for all
off-road driving until OR2 is needed. A smoother and
more comfortable ride will result. Press the “Up”
button once from the NRH position while the vehicle
speed is below 38 mph (61 km/h). When in the OR1
position, if the vehicle speed remains between 40 mph
(64 km/h) and 50 mph (80 km/h) for greater than
20 seconds or if the vehicle speed exceeds 50 mph
(80 km/h), the vehicle will be automatically lowered to
NRH. Refer to “Off-Road Driving Tips” in “Starting
and Operating” for further information.
• Off-Road 2 (OR2) (Raises the vehicle approximately
2.6 in (65 mm) – This position is intended for offroading
use only where maximum ground clearance is
required. To enter OR2, press the “Up” button twice
from the NRH position or once from the OR1 position
while vehicle speed is below 20 mph (32 km/h). While
in OR2, if the vehicle speed exceeds 25 mph (40 km/h)
the vehicle height will be automatically lowered to
OR1. Refer to “Off-Road Driving Tips” in “Starting
and Operating” for further information.
• Aero Mode (Lowers the vehicle approximately 0.5 in
(13 mm) – This position provides improved aerodynamics
by lowering the vehicle. The vehicle will
automatically enter Aero Mode when the vehicle
speed remains between 62 mph (99 km/h) and 66 mph
(106 km/h) for greater than 20 seconds or if the vehicle
speed exceeds 66 mph (106 km/h). The vehicle will
return to NRH from Aero Mode if the vehicle speed
remains between 30 mph (48 km/h) and 35 mph
(56 km/h) for greater than 20 seconds or if the vehicle
speed falls below 30 mph (48 km/h). The vehicle will
enter Aero Mode, regardless of vehicle speed if the
shift lever is in the “SPORT” position.
• Entry/Exit Mode (Lowers the vehicle approximately
1.5 in (38 mm) – This position lowers the vehicle for
easier passenger entry and exit as well as lowering the
rear of the vehicle for easier loading and unloading of
cargo. To enter Entry/Exit Mode, press the “Down”
button once from (NRH) while the vehicle speed is
below 25 mph (40 km/h). Once the vehicle speed goes
below 15 mph (24 km/h) the vehicle height will begin
to lower. If the vehicle speed remains between 15 mph
(24 km/h) and 25 mph (40 km/h) for greater than
60 seconds, or the vehicle speed exceeds 25 mph
(40 km/h) the Entry/Exit Mode change will be cancelled.
To exit Entry/Exit Mode, press the “Up” button
once while in Park Mode or drive the vehicle over
15 mph (24 km/h).
NOTE: Automatic lowering of the vehicle into Entry/Exit
Mode can be enabled through the Uconnect® Touch-
Screen Radio. If this feature is enabled, the vehicle will
only lower if the shift lever is in PARK, the terrain switch
is in AUTO, and the transfer-case is in AUTO”.
The Selec-Terrain™ switch will automatically change the
vehicle to the proper height based on the position of the
Selec-Terrain™ switch. The height can be changed from
the default Selec-Terrain™ setting by normal use of the
air suspension buttons. Refer to “Selec-Terrain™” in
“Starting and Operating” for further information.
The system requires that the engine be running for all
changes. When lowering the vehicle all of the doors,
including the liftgate, must be closed. If a door is opened
at any time while the vehicle is lowering the change will
not be completed until the open door(s) is closed.
The Quadra-Lift™ air suspension system uses a lifting
and lowering pattern which keeps the headlights from
incorrectly shining into oncoming traffic. When raising
the vehicle, the rear of the vehicle will move up first and
then the front. When lowering the vehicle, the front will
move down first and then the rear.
After the engine is turned off, it may be noticed that the
air suspension system operates briefly, this is normal. The
system is correcting the position of the vehicle to ensure
a proper appearance.
To assist with changing a spare tire, the Quadra-Lift™ air
suspension system has a feature which allows the automatic
leveling to be disabled. Refer to “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.
NOTE: If equipped with a touch screen radio all
enabling/disabling of air suspension features must be
done through the radio. Refer to “Uconnect™ Access
Settings” in “Understanding Your Instrument Panel” for
further information.
WARNING!
The air suspension system uses a high pressure
volume of air to operate the system. To avoid personal
injury or damage to the system, see your
authorized dealer for service.
Air Suspension Modes
The Air Suspension system has multiple modes to protect
the system in unique situations:
Tire/Jack Mode
To assist with changing a spare tire, the air suspension
system has a feature which allows the automatic leveling
to be disabled. Refer to “Uconnect® Access Settings”
in “Understanding Your Instrument Panel” for further
information.
NOTE: This mode is intended to be used with engine
running.
Transport Mode
To assist with flat bed towing, the air suspension system
has a feature which will put the vehicle into Entry/Exit
height and disable the automatic load leveling system.
Refer to “Electronic Vehicle Information Center (EVIC)”
in “Understanding Your Instrument Panel” for further
information.
Wheel Alignment Mode
Before performing a wheel alignment this mode must be
enabled. Refer to “Uconnect® Access Settings” in “Understanding
Your Instrument Panel” for further information.
NOTE: This mode is intended to be used with engine
running.
If equipped with a touch screen radio all enabling/
disabling of air suspension features must be done
through the radio. Refer to “Uconnect® Access Settings”
in “Understanding Your Instrument Panel” for further
information.

I can change from auto to sport on the move ,and go back . Then I can go to off road 1 &2 on the go too, but only under 60 km if I go over 60 km it will put it self down .And tall you to slow down if you would like to stay at that setting it's a safety thing !

You can disable QL completely by pulling a fuse or two if thats what you mean. I think it settles into entry/exit.

Otherwise no. Entry/exit is riding pretty much on the suspension stops.

I also think driving in that mode would be hard on cv joints and tires.

Transport Mode

has a feature which will put the vehicle into Entry/Exit
height and disable the automatic load leveling system.

What happens if you put the vehicle in transport mode and drive it? Does it automatically come out of transport mode? I'm not asking because I want to try it (and drive around at entry/exit mode), just asking because I am curious as to how the system works.

There are some height adjustment products available (modified parts) that allow you to set some slightly alternative heights for normal driving, but you cannot effectively "raise" something beyond what it's capable of. They don't change the limits, in other words. And driving at the limits is extremely uncomfortable, even at slow speeds if you hit a pebble...

No spacer lifts available as those are incompatible with QL. You could perhaps replace the air springs with a OME or elback spring type lift kit, but don't know anyone that has done that. You may need a donor vehicle (or a new front lower A arm assembly) for the front CLEVIS, however, as that part doesn't seem to be available separately. The upper shock mount has a part number. The rear looks like a simple swap.

Who's going to be the first to try it and report back here?

Thank you both for the info. Not the answer I was hoping for. Guess I should have gotten the limited vs overland. Well I size some 255/70 18s in there and see how we do.
