394 STARTING AND OPERATING

Fuel Economy (ECO) Mode
The Fuel Economy (ECO) mode can improve the vehi-
cle’s overall fuel economy during normal driving condi-
tions. Press the “eco” switch in the center stack of the
instrument panel and a amber light will indicate the ECO
mode is engaged.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 conser-
vative.
• Some ECO mode functions may be temporarily inhib-
ited based on temperature and other factors.
NOTE: When Sport Mode is enabled, the vehicle’s air
suspension system will operate in “Aero” Mode. Please
refer to “Quadra Lift” within this section for further
information.

switch between DRIVE and SPORT modes, tap the shift
lever rearward. SPORT mode is only accessible from
DRIVE.
NOTE:When Sport Mode is enabled, the vehicle’s air
suspension system will operate in “Aero” Mode. Please
refer to “Quadra Lift” within this section for further
information.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission may
operate only in certain gears, or may not shift at all.
Vehicle performance may be severely degraded and the
engine may stall. In some situations, the transmission
may not re-engage if the engine is turned off and
restarted. The Malfunction Indicator Light (MIL) may be illuminated. A message in the instrument cluster will
inform the driver of the more serious conditions, and
indicate what actions may be necessary.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
NOTE:
In cases where the instrument cluster message
indicates the transmission may not re-engage after en-
gine shutdown, perform this procedure only in a desired
location (preferably, at your authorized dealer).
1. Stop the vehicle.
2. Shift the transmission into PARK, if possible. If not, shift the transmission to NEUTRAL.
3. Turn the ignition switch to the OFF position. On vehicles with Keyless Enter-N-Go™, press and hold
the ignition switch until the engine turns OFF.
410 STARTING AND OPERATING

To disengage Paddle Shift mode, press and hold the (+)
shift paddle untilDorS is once again displayed in the
instrument cluster. You can shift in or out of Paddle Shift
mode at any time without taking your foot off the
accelerator pedal.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing a collision or
personal injury.
FOUR-WHEEL DRIVE OPERATION
Quadra-Trac I® Operating Instructions/
Precautions — If Equipped
The Quadra-Trac I® is a single-speed (HI range only)
transfer case, which provides convenient full-time four-
wheel drive. No driver interaction is required. The Brake Traction Control (BTC) System, which combines standard
ABS and Traction Control, provides resistance to any
wheel that is slipping to allow additional torque transfer
to wheels with traction.
NOTE:
The Quadra-Trac I® system is not appropriate
for conditions where 4WD LOW range is recommended.
Refer to “Off-Road Driving Tips” in “Starting and Oper-
ating” for further information.
Quadra-Trac II® Operating Instructions/
Precautions — If Equipped
The Quadra-Trac II® transfer case is fully automatic in
the normal driving 4WD AUTO mode. The Quadra-Trac
II® transfer case provides three mode positions:
• 4WD HI
• NEUTRAL
• 4WD LOW

STARTING AND OPERATING 413

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
NEUTRAL position without first fully engaging the
parking brake. The transfer case NEUTRAL position
disengages both the front and rear drive shafts from
the powertrain and will allow the vehicle to move
regardless of the transmission position. 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 “N”. 4. If vehicle is equipped with Quadra-Lift™ air suspen-
sion, ensure the vehicle is set to Normal Ride Height.
5. Using a ballpoint pen or similar object, press and hold the recessed transfer case “N” button (located by the
selector switch) for four seconds. The light behind the
“N” symbol will blink, indicating shift in progress.
The light will stop blinking (stay on solid) when the
shift to “N” is complete. A “FOUR WHEEL DRIVE
SYSTEM IN NEUTRAL” message will display on the
EVIC (Electronic Vehicle Information Center). Refer to
“Electronic Vehicle Information Center (EVIC)” in
“Understanding Your Instrument Panel” for further
information.
418 STARTING AND OPERATING

•The ignition switch must be in the ON/RUN position
for a shift to take place and for the position indicator
lights to be operable. If the ignition switch is not in the
ON/RUN position, the shift will not take place and no
position indicator lights will be on or flashing.
• A flashing “N” position indicator light indicates that
shift requirements have not been met.
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 func-
tions 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 information, preceding this section, for
shifting this system.SELEC-TERRAIN™ — IF EQUIPPED
Description
Selec-Terrain™ combines the capabilities of the vehicle
control systems, along with driver input, to provide the
best performance for all terrains.
