PARKING BRAKE
Electric Park Brake (EPB)
Your vehicle is equipped with a new Electric
Park Brake System (EPB) that offers greater
convenience. The park brake switch is lo-
cated in the center console.
To apply the park brake manually, pull up on
the switch momentarily. The BRAKE telltale
light in the instrument cluster and an indica-
tor on the switch will illuminate.To release the park brake manually, the igni-
tion must be in ON/RUN. Then put your foot
on the brake pedal and push the park brake
switch down momentarily. Once the park
brake is fully disengaged, the BRAKE telltale
light and the switch indicator will extinguish.
The park brake can also be automatically
released. With the engine running and the
transmission in gear, release the brake pedal
and depress the throttle pedal. For safety
reasons, your seat belt must also be fastened.
NOTE:
• You may hear a slight whirring sound from
the back of the vehicle while the parking
brake engages or disengages.
• If your foot is on the brake pedal while you are engaging or disengaging the parking
brake, you may notice a small amount of
brake pedal movement.
• The new Auto Park Brake feature can be used to apply the park brake automatically
every time you park the vehicle. Auto Park
Brake can be enabled and disabled in the
Settings menu in Uconnect. • The parking brake can be engaged even
when the ignition is OFF, however, it can
only be disengaged when the ignition is in
the ON/RUN mode.
•SafeHold a new feature that will automatically
apply the park brake under certain conditions.
The EPB monitors the status of the driver’s
seat belt, driver’s door and pedal positions to
determine if the driver may have exited while
the vehicle is still capable of moving and will
then automatically apply the park brake to
prevent the vehicle from rolling.
•The EPB fault light will illuminate if the EPB
switch is held for longer than 20 seconds in
either the released or applied position. The
light will extinguish upon releasing the
switch.
• Refer to the Starting And Operating section in the Owner’s Manual.
CAUTION!
If the Brake System Warning Light remains
on with the parking brake released, a brake
system malfunction is indicated. Have the
brake system serviced by an authorized
dealer immediately.Parking Brake Switch
STARTING AND OPERATING

For manual transmissions, the park brake will
automatically engage if all of the following
conditions are met:
• The vehicle is at a standstill.
• There is no attempt to depress the brakepedal or accelerator pedal.
• The clutch pedal is not pressed.
• The seat belt is unbuckled.
• The driver door is open.
SafeHold can be temporarily bypassed by
pushing the Electric Park Brake Switch while
the driver door is open. Once manually by-
passed, SafeHold will be enabled again once
the vehicle reaches 12 mph (20 km/h) or the
ignition is turned to the OFF position and
back to ON again.MANUAL TRANSMISSION —
IF EQUIPPED
WARNING!
You or others could be injured if you leave
the vehicle unattended without having the
parking brake fully applied. The parking
brake should always be applied when the
driver is not in the vehicle, especially on
an incline.
CAUTION!
Never drive with your foot resting on the
clutch pedal, or attempt to hold the ve-
hicle on a hill with the clutch pedal par-
tially engaged, as this will cause abnormal
wear on the clutch. NOTE:
During cold weather, you may experience
increased effort in shifting until the transmis-
sion fluid warms up. This is normal.
Shifting
Fully press the clutch pedal before shifting
gears. As you release the clutch pedal, lightly
press the accelerator pedal.
You should always use first gear when starting
from a standing position.
Recommended Vehicle Shift Speeds
To utilize your manual transmission effi-
ciently for fuel economy and performance, it
should be upshifted as listed in the recom-
mended shift speed chart. Shift at the ve-
hicle speeds listed for acceleration. When
heavily loaded or pulling a trailer, these rec-
ommended up-shift speeds may not apply.

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.
Activating The Rear E-Locker
To activate the Rear E-Locker System, the
following conditions must be met:
1. The 4WD system must be in 4WD LOW.
2. The ignition in the ON mode and the engine running.
3. Vehicle speed must be below 15 MPH (24 km/h).
4. To engage Rear E-Locker, push the REAR LOCK button once.
Deactivating The Rear E-Locker System
To deactivate the Rear E-Locker System, the
following conditions must be met:

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.
SELEC-TERRAIN
Description
Selec-Terrain combines the capabilities of
the vehicle control systems, along with driver
input, to provide the best performance for all
terrains.
Rotate the Selec-Terrain knob to select the
desired mode. Selec-Terrain offers the following modes:
•
Auto — Fully automatic full time four-wheel
drive operation can be used on and off road.
Balances traction with seamless steering
feel to provide improved handling and ac-
celeration over two-wheel drive vehicles.
• Snow — Tuning set for additional stability
in inclement weather. Use on and off road
on loose traction surfaces such as snow.
When in SNOW mode (depending on cer-
Selec-Terrain Switch
135

tain operating conditions), the transmis-
sion may use second gear (rather than first
gear) during launches, to minimize wheel
slippage.
• Sport — This mode alters the transmis-
sion's automatic shift schedule for sportier
driving. Upshift speeds are increased to
make full use of available engine power.
NOTE:
SPORT mode is not available when 4WD LOW
is selected.
• Sand/Mud — Off-road calibration for use on
low traction surfaces such as mud, sand, or
wet grass. Driveline is maximized for trac-
tion. Some binding may be felt on less
forgiving surfaces. The electronic brake
controls are set to limit traction control
management of throttle and wheel spin.
• Rock — Off-road calibration only available
in 4WD LOW range. Traction based tuning
with improved steer-ability for use on high
traction off-road surfaces. Use for low
speed obstacles such as large rocks, deep
ruts, etc. NOTE:
• Rock mode is only available on the vehicles
equipped with the Off-Road package.
• Activate the Hill Descent Control or Selec Speed Control for steep downhill control.
See “Electronic Brake Control System” in
“Safety” for further information.
