116 STARTING AND OPERATING
Aero Mode (Lowers the vehicle approximately
0.6 inches (15 mm)) – This position provides
improved aerodynamics by lowering the
vehicle. The vehicle will automatically enter
Aero Mode when the vehicle speed remains
between 52 mph (83 km/h) and 56 mph
(90 km/h) for greater than 20 seconds or if
the vehicle speed exceeds 56 mph (90 km/h).
The vehicle will return to NRH from Aero Mode
if the vehicle speed remains between 20 mph
(32 km/h) and 25 mph (40 km/h) for greater
than 20 seconds or if the vehicle speed falls
below 20 mph (32 km/h). The vehicle will
enter Aero Mode, regardless of vehicle speed
if the vehicle is in “SPORT” mode.
Entry/Exit Mode (Lowers the vehicle approxi-
mately 1.6 inches (40 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, push 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 canceled. To exit
Entry/Exit Mode, press the “Up” button once
while in Entry/Exit 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
Touchscreen Radio. If this feature is enabled,
the vehicle will only lower if the gear selector is
in "PARK", the terrain switch is in "AUTO", the
transfer case is in "AUTO” and the vehicle level
should be either in Normal or Aero Mode. The
vehicle will not automatically lower if the air
suspension level is in OR2 or OR1. If the vehicle
is equipped with Intrusion Theft Module (ITM),
the lowering will be suppressed when the igni-
tion is switched OFF and the door is open to
prevent setting the alarm off.
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 Ú page 119.
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/are 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 Ú page 171.
