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

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 between these gears.
The transmission shift lever has PARK, REVERSE, NEU-
TRAL, DRIVE, and Electronic Range Select (ERS) shift
positions. Manual downshifts can be made using the ERS
shift control (refer to#Electronic Range Select (ERS)
Operation#in this section for further information). Mov-
ing the shift lever into the ERS (-/+) position (beside the
DRIVE position) activates ERS mode, displays the cur-
rent gear in the instrument cluster, and prevents auto-
matic upshifts beyond this gear. In ERS mode, toggling
the shift lever forward (-) or rearward (+) will change the
highest available gear.
NOTE:If the shift lever cannot be moved to the PARK,
REVERSE, or NEUTRAL position (when pushed for-
ward) it is probably in the ERS (+/-) position (beside the
DRIVE position). In ERS mode, the transmission gear
limit (1, 2, 3, etc.) is displayed in the instrument cluster.
Move the shift lever to the right (into the DRIVE [D]
position) for access to PARK, REVERSE, and NEUTRAL.

STARTING AND OPERATING 485

CAUTION!
•Before moving the shift lever out of PARK, you
must turn the ignition switch from the LOCK/OFF
position to the ON/RUN position, and also press
the brake pedal. Otherwise, damage to the shift
lever could result.
•DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range, as this
can damage the drivetrain.
The following indicators should be used to ensure that
you have engaged the transmission into the PARK posi-
tion:
•When shifting into PARK, press the lock button on the
shift lever and firmly move the lever all the way
forward until it stops and is fully seated.
•Look at the transmission gear position display and
verify that it indicates the PARK position (P).
•With brake pedal released, verify that the shift lever
will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. The engine may be
started in this range. Apply the parking brake and shift
the transmission into PARK if you must leave the vehicle.

STARTING AND OPERATING 489

to operate. The Malfunction Indicator Light (MIL) may be
illuminated. Limp Home Mode allows the vehicle to be
driven to an authorized dealer for service without dam-
aging the transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition switch to the OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to normal
operation.
NOTE:Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur. If the transmission cannot be reset, authorized
dealer service is required.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear. For example, if
you shift the transmission into 5 (fifth gear), the trans-
mission will not shift above fifth gear, but will shift
through the lower gears normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the shift lever is in the DRIVE
position, the transmission will operate automatically,
shifting between all available gears.
492 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).

STARTING AND OPERATING 497

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

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 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 and shift the
transmission to PARK.
2. Turn the engine OFF.
3. Turn the ignition switch to the ON/RUN position, 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, press 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 blink-
ing (stay on solid) when the shift to NEUTRAL (N) is
complete.
500 STARTING AND OPERATING

•Shifting into or out of Rear E-Locker 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 for the vehicle to be rolling,
below 15 MPH (24 km/h), while including right and
left steering maneuvers to allow for the clutch teeth to
align.
•The Rear E-Locker System must be disengaged prior to
taking the vehicle out of 4WD LOW range. If 4WD
LOW 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.

Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine, transmission, Power Trans-
fer Unit and Rear Drive Module) to assure they have not
been contaminated. Contaminated fluids and lubricants
(milky, foamy in appearance) should be flushed/changed
as soon as possible to prevent component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the 4WD system to the appropriate terrain
mode, using 4WD LOW if necessary. Refer to “Four-
Wheel Drive Operation” in “Starting and Operating” for
further information. Do not shift to a lower gear than
necessary to maintain headway. Over-revving the engine
can spin the wheels and traction will be lost.
Avoid abrupt downshifts on icy or slippery roads be-
cause engine braking may cause skidding and loss of
control.
Hill Climbing
NOTE:Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill,shift the transmission to a
lower gear and shift the 4WD System to 4WD LOW. Use
first gear and 4WD LOW for very steep hills.
If you stall or begin to lose headwaywhile climbing a
steep hill, allow your vehicle to come to a stop and
immediately apply the brakes. Restart the engine and
shift to REVERSE. Back slowly down the hill allowing the
compression braking of the engine to help regulate your
speed. If the brakes are required to control vehicle speed,
apply them lightly and avoid locking or skidding the
tires.

will sound. The rear stop lamps will also be illuminated
automatically while the vehicle remains in motion.
To disengage the parking brake while the vehicle is in
motion, release the switch. If the vehicle is brought to a
complete stop using the parking brake, when the vehicle
reaches approximately 3 mph, (5 km/h) the parking
brake will remain engaged.
WARNING!
Driving the vehicle with the parking brake engaged,
or repeated use of the parking brake to slow the
vehicle may cause serious damage to the brake sys-
tem.
In the unlikely event of a malfunction of the Electric Park
Brake system, a yellow EPB fault lamp will illuminate.
This may be accompanied by the Brake warning lamp
flashing. In this event, urgent service of the electric park
brake system is required. Do not rely on the parking
brake to hold the vehicle stationary.
Auto Park Brake
The electric park brake can be programmed to be applied
automatically whenever the vehicle is at a standstill and
the automatic transmission is placed in PARK, or with a
manual transmission, whenever the ignition switch is
turned “OFF”. Auto Park Brake is enabled and disabled
by customer selection through the customer program-
mable features section of the Uconnect® Settings.
Any single auto park brake application can be bypassed
by pressing the EPB switch to the release position while
the transmission is placed in PARK.
