light on the switch indicates when ECO mode is disabled
(for regular models) or a blue light when enabled (for SRT
models).
When the Fuel Economy (ECO) Mode is engaged, the
vehicle control systems will change the following:
•The transmission will upshift sooner and downshift
later.
• The overall driving performance will be more conserva-
tive. •
Vehicles with Quadra-Lift air suspension will operate in
Aero mode over a broader speed range. Refer to the
section on Quadra-Lift for further information.
• In SRT models, the transmission will launch (from a
stop) in second gear, and the torque converter clutch
may engage at lower engine speeds and remain on
longer.
• Some ECO mode functions may be temporarily inhib-
ited based on temperature and other factors.
Active Noise Cancellation — Summit And SRT
Models Only
Your vehicle is equipped with an Active Noise Cancellation
System. This system uses four microphones embedded in
the headliner to detect undesirable exhaust noise, which
sometimes occurs when operating in ECO mode. An
onboard frequency generator creates counteracting sound
waves through the audio system to help keep the vehicle
quiet.
Eight–Speed Automatic Transmission
The transmission gear range (PRNDM) is displayed both
beside the gear selector and in the instrument cluster. To
select a gear range, press the lock button on the gear
selector and move the selector rearward or forward. To

NOTE:
•If shift conditions/interlocks are not met, or a transfer
case motor temperature protection condition exists, a
“For 4x4 High Slow Below 3 mph (5 km/h) Put Trans in
N push 4 Low” message will flash from the instrument
cluster display. Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for further
information.
• Shifting into or out of 4WD LOW is possible with the
vehicle completely stopped; however, difficulty may
occur due to the mating clutch teeth not being properly
aligned. Several attempts may be required for clutch
teeth alignment and shift completion to occur. The
preferred method is with the vehicle rolling 0 to 3 mph
(0 to 5 km/h). If the vehicle is moving faster than 3 mph
(5 km/h), the transfer case will not allow the shift.
Shifting Into NEUTRAL (N)
WARNING!
You or others could be injured or killed if you leave the
vehicle unattended with the transfer case in the NEU-
TRAL (N) position without first fully engaging the
(Continued)
WARNING! (Continued)
parking brake. The NEUTRAL (N) position disengages
both the front and rear drive shafts from the pow-
ertrain and will allow the vehicle to roll, even if the
transmission is in PARK. The parking brake should
always be applied when the driver is not in the vehicle.
1. Bring the vehicle to a complete stop, with the engine running.
2. Press and hold the brake pedal.
3. Shift the transmission into NEUTRAL.
4. If vehicle is equipped with Quadra-Lift air suspension, ensure the vehicle is set to Normal Ride Height.
5. Using a ballpoint pen or similar object, push and hold the recessed transfer case NEUTRAL (N) button (located
by the selector switch) for four seconds. The light
behind the NEUTRAL (N) symbol will blink, indicating
shift in progress. The light will stop blinking (stay on
solid) when the shift to NEUTRAL (N) is complete. A
“NEUTRAL” message will appear in the instrument
cluster display. Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for further
information.
286 STARTING AND OPERATING

7. When the NEUTRAL (N) indicator light turns off,release the NEUTRAL (N) button.
8. After the NEUTRAL (N) button has been released, the transfer case will shift to the position indicated by the
selector switch.
Quadra-Drive II System — If Equipped
The optional Quadra-Drive II System features two torque
transfer couplings. The couplings include an Electronic
Limited-Slip Differential (ELSD) rear axle and the Quadra-
Trac II transfer case. The optional ELSD axle is fully
automatic and requires no driver input to operate. Under normal driving conditions, the unit functions as a standard
axle, balancing torque evenly between left and right
wheels. With a traction difference between left and right
wheels, the coupling will sense a speed difference. As one
wheel begins to spin faster than the other, torque will
automatically transfer from the wheel that has less traction,
to the wheel that has traction. While the transfer case and
axle coupling differ in design, their operation is similar.
Follow the Quadra-Trac II transfer case shifting informa-
tion, preceding this section, for shifting this system.
QUADRA-LIFT — IF EQUIPPED
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. The vehicle will
automatically raise and lower the ride height to adapt to
the appropriate driving conditions. At higher speeds, the
vehicle will lower to an aerodynamic ride height and when
operating in off-road modes, the vehicle will raise the ride
height accordingly. The buttons near the terrain switch in
the center console area can be used to set preferred ride
height to match the appropriate conditions.

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 approximately 1.6
inces (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 cancelled. 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 Touch-Screen
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
Off Rd 2 or Off Rd 1. If the vehicle is equipped with
Intrusion Theft Module (ITM), the lowering will be sup-
pressed when the ignition 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. 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.
290 STARTING AND OPERATING

The Quadra-Lift air suspension system uses a lifting and
lowering pattern which keeps the headlights from incor-
rectly 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 auto-
matic leveling to be disabled. Refer to “Uconnect Settings”
in “Multimedia” 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 Settings” in “Multimedia” for
further information.
WARNING!
The air suspension system uses a high pressure vol-
ume of air to operate the system. To avoid personal
