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

Additionally, on dry pavement under heavy
throttle input (where one may have no wheel
spin), torque will be sent to the rear in a
pre-emptive effort to improve vehicle launch
and performance characteristics.
CAUTION!
All wheels must have the same size and type
tires. Unequal tire sizes must not be used.
Unequal tire size may cause failure of the
power transfer unit.
2-Speed Four-Wheel Drive (4x4) —
If Equipped
The Four-Wheel Drive is fully automatic in the
normal driving mode. The Selec-Terrain but-
tons provide three selectable mode positions:
• 4WD LOW
• REAR LOCK (If Equipped)
• NEUTRAL
1-Speed 4X4 Switch
2-Speed 4x4 Switch
2-Speed 4x4 Switch (with Rear Lock)
131

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

2. The ignition in the ON mode and theengine running.
3. To disengage Rear E-Locker, push the REAR LOCK button once.
NOTE:
• It may also be necessary to drive slowly steering back and forth to complete en-
gagement and disengagement of the
E-Locker.
• When engaging Rear E-Locker, the indica- tor lights in the instrument cluster and on
the REAR LOCK button will begin to flash.
When the shift is complete the REAR LOCK
indicator lights will remain on.
• When disengaging Rear E-Locker, the indi- cator lights in the instrument cluster and on
the REAR LOCK button will begin to flash.
When the shift is complete the REAR LOCK
indicator lights will remain off.
• 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 prop-
erly aligned. Several attempts may be re-
quired 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 disen- gaged prior to taking the vehicle out of 4WD
LOW range. If 4WD LOW shift conditions/
interlocks are not met, a message will flash
from the instrument cluster display with
instructions on how to complete the re-
quested shift.

ranty.
STARTING AND OPERATING
158

Proper towing or lifting equipment is required
to prevent damage to your vehicle. Use only
tow bars and other equipment designed for
this purpose, following equipment manufac-
turer’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing
devices to main structural members of the
vehicle, not to bumpers or associated brack-
ets. State and local laws regarding vehicles
under tow must be observed.
NOTE:
• You must ensure that the Auto Park Brakefeature is disabled before towing this ve-
hicle, to avoid inadvertent Electric Park
Brake engagement. The Auto Park Brake
feature is enabled or disabled via the cus-
tomer programmable features in the
Uconnect Settings.
• Vehicles with a discharged battery or total electrical failure when the electric park
brake (EPB) is engaged, will need a wheel
dolly or jack to raise the rear wheels off the
ground when moving the vehicle onto a
flatbed. If you must use the accessories (wipers, de-
frosters, etc.) while being towed, the ignition
must be in the ON/RUN mode, not the ACC
mode.
Note that the Safehold feature will engage
the Electric Park Brake whenever the driver's
door is opened (if the battery is connected,
ignition is ON, transmission is not in PARK,
and brake pedal is released). If you are towing
this vehicle with the ignition in the ON/RUN
mode, you must manually disable the Elec-
tric Park Brake each time the driver's door is
opened, by pressing the brake pedal and then
releasing the EPB.
If the vehicle’s battery is discharged, refer to
“Gear Selector Override” in this section for
instructions on shifting the automatic trans-
mission out of PARK so that the vehicle can
be moved.
CAUTION!
• Do not use sling-type equipment when
towing. Vehicle damage may occur.
• When securing the vehicle to a flatbed
truck, do not attach to front or rear

suspension components. Damage to
your vehicle may result from improper
towing.
• Ensure that the Electric Park Brake is
released, and remains released, while
being towed.
Without The Key Fob
Special care must be taken when the vehicle
is towed with the ignition in the LOCK/OFF
mode. The only approved method of towing
without the key fob is with a flatbed truck.
Proper towing equipment is necessary to pre-
vent damage to the vehicle.
