468 STARTING AND OPERATING

Conditions That Will Cause The Engine To Start Auto-
matically While In Autostop Mode:
•The transmission selector is moved out of DRIVE.
•To maintain cabin temperature comfort.
•HVAC is set to full defrost mode.
•HVAC system temperature or fan speed is manually
adjusted.
•Battery voltage drops too low.
•Low brake vacuum (e.g. after several brake pedal
applications).
•STOP/START OFF switch is pressed.
•A STOP/START system error occurs.
•4WD system is put into 4LO mode.
Conditions That Force An Application Of The Electric
Park Brake While In Autostop Mode:
•The drivers door is open and brake pedal released.
•The drivers door is open and the drivers seat belt is
unbuckled.
•The engine hood has been opened.
•A STOP/START system error occurs.
If the Electric Park Brake is applied with the engine off,
the engine may require a manual restart and the electric
park brake may require a manual release (depress brake
pedal and press Electric Park Brake switch). Refer to
“Electronic Vehicle Information Center (EVIC)” or
“Driver Information Display (DID)” in “Understanding
Your Instrument Panel” for further information.
478 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. To activate ECO mode press the “Controls” button
on the touchscreen and then press the “ECO” button on
the touchscreen. When ECO mode is engaged a green
light in the center stack of the instrument panel will be
illuminated and a green ECO light will also illuminate in
the Electronic Vehicle Information Center (EVIC) or
Driver Information Display (DID). In 4WD models, ECO
mode is only active in ’4WD Auto’ driving mode. If you
switch to another driving mode the ECO button will turn
grey and the ECO light in the instrument panel will
disappear indicating it is no longer in ECO mode. It will
automatically re-enable ECO mode when you switch
back into 4WD Auto.
Nine-Speed Automatic Transmission
The transmission gear range (PRND) is displayed both
beside the shift lever and in the Electronic Vehicle Infor-
mation Center (EVIC)/Driver Information Display
(DID). To select a gear range, press the lock button on the
shift lever and move the lever rearward or forward. You
must also press the brake pedal to shift the transmission
out of PARK, or to shift from NEUTRAL into DRIVE or
REVERSE when the vehicle is stopped or moving at low
speeds (refer to#Brake/Transmission Shift Interlock Sys-
tem#in this section). Select the DRIVE range for normal
driving.
The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating; therefore, the first few shifts on a new
vehicle may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles (kilometers).
484 STARTING AND OPERATING

The Four-Wheel Drive is fully automatic in the normal
driving mode. The Selec-Terrain buttons provide three
selectable mode positions:
•4WD LOW
•REAR LOCK (If Equipped)
•NEUTRAL
When additional traction is required, the 4WD LOW
range position can be used to provide an additional gear
reduction which allows for increased torque to be deliv-
ered to both the front and rear wheels. 4WD LOW is
intended for loose, slippery road surfaces only. Driving in
4WD LOW on dry, hard-surfaced roads may cause in-
creased tire wear and damage to driveline components.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the normal
driving mode at a given road speed. Take care not to
overspeed the engine and do not exceed 25 mph
(40 km/h).
Proper operation of four-wheel drive vehicles depends
on tires of equal size, type, and circumference on each
wheel. Any difference will adversely affect shifting and
cause damage to the driveline components.
2-Speed 4x4 Switch (with Rear Lock)
496 STARTING AND OPERATING

Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
Shift Positions
For additional information on the appropriate use of each
4WD system mode position, see the information below:
NEUTRAL
This range disengages the driveline from the powertrain.
It is to be used for flat towing behind another vehicle.
Refer to “Recreational Towing” in “Starting and Operat-
ing” for further information.
WARNING!
You or others could be injured or killed if you leave
the vehicle unattended with the power transfer unit
(Continued)
WARNING!(Continued)
in the NEUTRAL (N) position without first fully
engaging the parking brake. The NEUTRAL (N)
position disengages both the front and rear drive
shafts from the powertrain 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.
4WD LOW
This range is for low speed four-wheel drive. It provides
an additional gear reduction which allows for increased
torque to be delivered to both the front and rear wheels
while providing maximum pulling power for loose,
slippery road surfaces only. Do not exceed 25 mph
(40 km/h).

NOTE:Refer to “Selec-Terrain® – If Equipped” for fur-
ther information on the various positions and their
intended usages.
Shifting Procedures
Shifting Into 4X4 LOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the
ignition switch in the ON position and the engine run-
ning, shift the transmission into NEUTRAL, and press
the “4WD LOW” button once. The “4WD LOW” indica-
tor light in the instrument cluster will begin to flash and
remain on solid when the shift is complete.Selec-Terrain Switch
498 STARTING AND OPERATING

NOTE:If shift conditions/interlocks are not met a mes-
sage will flash from the Electronic Vehicle Information
Center (EVIC)/Driver Information Display (DID) with
instructions on how to complete the requested shift.
Refer to “Electronic Vehicle Information Center (EVIC)/
Driver Information Display (DID) in “Understanding
Your Instrument Panel” for further information.
Shifting Out Of 4X4 LOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the
ignition switch in the ON position and the engine run-
ning, shift the transmission into NEUTRAL, and press
the “4WD LOW” button once. The “4WD LOW” indica-
tor light in the instrument cluster will flash and go out
when the shift is complete.
NOTE:
•If shift conditions/interlocks are not met, a message
will flash from the Electronic Vehicle Information
Center (EVIC)/Driver Information Display (DID) with
instructions on how to complete the requested shift.
Refer to “Electronic Vehicle Information Center
(EVIC)/Driver Information Display (DID) in “Under-
standing Your Instrument Panel” for further informa-
tion.
•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 prop-
erly 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 4WD system will not allow
the shift.

STARTING AND OPERATING 499

7. After the shift is completed and the NEUTRAL (N)
light stays on, release the NEUTRAL (N) button.
8. Start the engine.
9. Shift the transmission into REVERSE.
10. Release the brake pedal for five seconds and ensure
that there is no vehicle movement.
11. Shift the transmission to NEUTRAL.
12. Apply the parking brake.
13. Shift the transmission into PARK, turn the engine
OFF, and remove the key fob.
Repeat steps 1-7 to shift out of NEUTRAL.
Rear Electronic Locker (E-Locker) System — If
Equipped
The Rear E-Locker System features a mechanical locking
rear differential to provide better traction in the 4WD
LOW position. The “REAR LOCK” button is on the
Selec-Terrain Knob.
