CAUTION!
If you skip a gear while downshifting or
downshift at too high of a vehicle speed,
these conditions may cause the engine to
overspeed if too low of a gear is selected
and the clutch pedal is released. Damage
to the clutch and the transmission can
result from skipping a gear while down-
shifting or downshifting at too high of a
vehicle speed even if the clutch pedal is
held pressed (i.e., not released).
AUTOMATIC
TRANSMISSION —
IF EQUIPPED
WARNING!
• It is dangerous to shift out of PARK orNEUTRAL if the engine speed is higher
than idle speed. If your foot is not firmly
pressing the brake pedal, the vehicle
could accelerate quickly forward or in
reverse. You could lose control of the
WARNING!
vehicle and hit someone or something.
Only shift into gear when the engine is
idling normally and your foot is firmly
pressing the brake pedal.
• Unintended movement of a vehicle
could injure those in or near the vehicle.
As with all vehicles, you should never
exit a vehicle while the engine is run-
ning. Before exiting a vehicle, always
come to a complete stop, then apply the
parking brake, shift the transmission
into PARK, turn the engine OFF, and
remove the key fob. When the ignition is
in the LOCK/OFF (key removal) position,
(or, with Keyless Enter-N-Go, when the
ignition is in the OFF mode) the trans-
mission is locked in PARK, securing the
vehicle against unwanted movement.
• When leaving the vehicle, always make
sure the ignition is in the OFF mode,
remove the key fob from the vehicle, and
lock the vehicle.
•
Never use the PARK position as a substi-
tute for the parking brake. Always apply the
parking brake fully when exiting the ve-
WARNING!
hicle to guard against vehicle movement
and possible injury or damage.
• Your vehicle could move and injure you
and others if it is not in PARK. Check by
trying to move the gear selector out of
PARK with the brake pedal released.
Make sure the transmission is in PARK
before exiting the vehicle.
• Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
Allowing children to be in a vehicle un-
attended is dangerous for a number of
reasons. A child or others could be seri-
ously or fatally injured. Children should
be warned not to touch the parking
brake, brake pedal or the transmission
gear selector.
• Do not leave the key fob in or near the
vehicle (or in a location accessible to
children), and do not leave the ignition
(in a vehicle equipped with Keyless
Enter-N-Go) in the ACC or ON/RUN
mode. A child could operate power win-
dows, other controls, or move the ve-
hicle.

some vehicle and driveline combinations uti-
lize 9th gear only in very specific driving
situations and conditions.
Only shift from DRIVE to PARK or REVERSE
when the accelerator pedal is released and
the vehicle is stopped. Be sure to keep your
foot on the brake pedal when shifting be-
tween these gears.
The transmission gear selector provides
PARK, REVERSE, NEUTRAL, DRIVE, and
Electronic Range Select (ERS) shift posi-
tions. Manual downshifts can be made using
the ERS shift control. Moving the gear selec-
tor into the ERS (-/+) position (beside the
DRIVE position) activates ERS mode, dis-
plays the current gear in the instrument clus-
ter, and prevents automatic upshifts beyond
this gear. In ERS mode, toggling the gear
selector forward (-) or rearward (+) will
change the highest available gear.
Refer to “Electronic Range Select (ERS) Op-
eration” in the Owner’s Manual.NOTE:
If the gear selector cannot be moved to the
PARK, REVERSE, or NEUTRAL position
(when pushed forward) it is probably in the
ERS (+/-) position (beside the DRIVE posi-
tion). In ERS mode, the transmission gear
limit (1, 2, 3, etc.) is displayed in the instru-
ment cluster. Move the gear selector to the
right (into the DRIVE [D] position) for access
to PARK, REVERSE, and NEUTRAL.FOUR-WHEEL DRIVE
OPERATION
1-Speed Four-Wheel Drive (4X4) —
If Equipped
This feature provides on-demand four-wheel
drive (4X4). The system is automatic with no
driver inputs or additional driving skills re-
quired. Under normal driving conditions, the
front wheels provide most of the traction. If
the front wheels begin to lose traction, power
is shifted automatically to the rear wheels.
The greater the front wheel traction loss, the
greater the power transfer to the rear wheels.
Gear Selector
STARTING AND OPERATING
130

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 delivered 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 increased 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 dam-
age to the driveline components.
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.
WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
power transfer unit 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 automatic
transmission is in PARK (or manual trans-
mission is in gear). 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 deliv-
ered 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
further 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 in the ON mode and the
engine running, shift the transmission into
NEUTRAL, and push the “4WD LOW” button
once. The “4WD LOW” indicator light in the
instrument cluster will begin to flash and
remain on solid when the shift is complete.
STARTING AND OPERATING
132

NOTE:
If shift conditions/interlocks are not met, a
message will flash from the instrument clus-
ter display with instructions on how to com-
plete the requested shift. Refer to “Instru-
ment Cluster Display” in “Getting To know
Your Instrument Panel” for further informa-
tion.
Shifting Out Of 4X4 LOW
With the vehicle at speeds of 0 to 3 mph (0 to
5 km/h), the ignition in the ON mode and the
engine running, shift the transmission into
NEUTRAL, and push the “4WD LOW” button
once. The “4WD LOW” indicator light in the
instrument cluster will flash and go out when
the shift is complete.
NOTE:
• If shift conditions/interlocks are not met, amessage will flash from the instrument
cluster display with instructions on how to
complete the requested shift. Refer to “In-
strument 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 at-
tempts may be required for clutch teeth align-
ment and shift completion to occur. The pre-
ferred 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.
NEUTRAL Shift Procedure
WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
power transfer unit 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 automatic
transmission is in PARK (or manual trans-
mission is in gear). The parking brake
should always be applied when the driver
is not in the vehicle.
1. Bring the vehicle to a complete stop on level ground and shift the automatic
transmission to PARK.
2. Turn the engine OFF.
3. Turn the ignition to the ON/RUN mode, but do not start the engine.
4. Press and hold the brake pedal.

5. Shift the transmission into NEUTRAL.
6. Using a ballpoint pen or similar object,push and hold the recessed power transfer
unit 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. 7. After the shift is completed and the NEU-
TRAL (N) light stays on, release the NEU-
TRAL (N) button.
8. Start the engine.
9. Release the parking brake.
10. Shift the transmission into REVERSE.
11. Release the brake pedal (and clutch pedal on manual transmissions) for five
seconds and ensure that there is no
vehicle movement.
12. Shift the transmission to NEUTRAL.
13. Apply the parking brake.
14. Shift the automatic transmission into PARK, or place manual transmission in
gear (NOT in Neutral). 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 me-
chanical locking rear differential to provide
better traction in the 4WD LOW position. The
“REAR LOCK” button is on the Selec-Terrain
Knob.
