Quadra-Lift™
• The Quadra-Lift™ air suspension
system provides full time load
leveling capability along with the
benefit of being able to adjust
vehicle height by the push of a
button. Quadra-Lift™ is available
with both Quadra-Trac II
®
and
Quadra-Drive II™.
• 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.
• The Quadra-Lift™ air suspension
system uses a lifting and lowering
pattern which keeps the headlights
from 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, you
may notice that the air suspension
system operates briefly. This is
normal. The system is correcting
the position of the vehicle.
• To assist with changing a spare tire,
the Quadra-Lift™ 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.
Driving the vehicle over 5 mph
(8 km/h) will return the air
suspension to normal operation.
• An audible chime will be heard
whenever a system error has been
detected.
Operation
• Pressing the “Up” or “Down” button
once will move the suspension one
position higher or lower from the
current position, assuming all
conditions are met (i.e., engine
running and all doors and liftgate
closed).
• The 4 indicator lamps will illuminate
to show the current position of the
vehicle. Flashing indicator lamps
will show a position which the
system is working to achieve. If
multiple indicator lamps are flashing
on the “Up” button, the highest
flashing indicator lamp is the
position the system is working to
achieve.
• Normal Ride Height
(NRH) – This is the
standard position of the
suspension and is
meant for normal
driving. Only the bottom Indicator
lamp on the “Up” button will be
illuminated when the vehicle is in
this position.
