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
located in the center console.Park Brake Switch
To apply the park brake manually, pull up on
the switch momentarily. The BRAKE telltale
light in the instrument cluster and an indi -
cator 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 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 is a feature that will automati -
cally 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 automati -
cally 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 90
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.
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
is turned “OFF”. Auto Park Brake is enabled
and disabled by customer selection through
the Customer Programmable Features
section of the Uconnect Settings.
Any single auto park brake application can
be bypassed by pushing the EPB switch to
the release position while the transmission is
placed in PARK.
WARNING!
Never use the PARK position as a substi-
tute for the parking brake. Always apply
the parking brake fully when exiting the
vehicle to guard against vehicle move-
ment and possible injury or damage.
When exiting the vehicle, always make
sure the ignition is in the OFF mode,
remove the key fob from the vehicle, and
lock your vehicle.
Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended 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 the ACC or ON/RUN mode. A child
could operate power windows, other
controls, or move the vehicle.
Be sure the parking brake is fully disen -
gaged before driving; failure to do so can
lead to brake failure and a collision.
Always fully apply the parking brake
when leaving your vehicle, or it may roll
and cause damage or injury. Also be
certain to leave the transmission in
PARK. Failure to do so may allow the
vehicle to roll and cause damage or
injury.

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 system.

WARNING! (Continued) 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.

SafeHold
SafeHold is a safety feature of the Electric
Park Brake System that will engage the park
brake automatically if the vehicle is left
unsecured while the ignition is in ON/RUN.
For automatic 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 brake
pedal or accelerator pedal.
The seat belt is unbuckled.
The driver door is open.
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 brake
pedal or accelerator pedal.
The clutch pedal is not pressed.
The seat belt is unbuckled.
The driver door is open.
MANUAL TRANSMISSION —
IF EQUIPPED NOTE:
During cold weather, you may experience
increased effort in shifting until the trans -
mission 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.
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
vehicle on a hill with the clutch pedal
partially engaged, as this will cause
abnormal wear on the clutch.
Do not drive with your hand resting on
the gear selector as the force exerted,
even if slight, could lead over time to
premature wear of the gearbox internal
components.

Recommended Vehicle Shift Speeds
To utilize your manual transmission efficiently for fuel economy and performance, it should be upshifted as listed in the recommended shift
speed chart. Shift at the vehicle speeds listed for acceleration. When heavily loaded or pulling a trailer, these recommended up-shift speeds
may not apply.
Downshifting
Moving from a high gear down to a lower gear
is recommended to preserve brakes when
driving down steep hills. In addition, down-
shifting at the right time provides better
acceleration when you desire to resume
speed. Downshift progressively. Do not skip
gears to avoid overspeeding the engine and
clutch.
Manual Transmission Shift Speeds in MPH (KM/H)
All Engines Gear Selection 2 to 33 to 44 to 55 to 6
Accel. 24 (39) 34 (55) 47 (76) 56 (90)
Cruise 19 (31) 27 (43) 37 (60) 41 (66)
WARNING!
Do not downshift for additional engine
braking on a slippery surface. The drive
wheels could lose their grip, and the
vehicle could skid.
CAUTION!
Skipping gears and downshifting into
lower gears at higher vehicle speeds can
damage the engine and clutch systems,
Any attempt to shift into lower gear with
clutch pedal depressed may result
damage to the clutch system. Shifting
into lower gear and releasing the clutch
may result in engine damage.
When descending a hill, be very careful
to downshift one gear at a time to
prevent overspeeding the engine which
can cause engine damage, and/or clutch
damage, even if the clutch pedal is
pressed. If transfer case is in low range
the vehicle speeds to cause engine and
clutch damage are significantly lower.
Failure to follow the maximum recom -
mended downshifting speeds may cause
the engine damage and/or damage the
clutch, even if the clutch pedal is
pressed.
Descending a hill in low range with
clutch pedal depressed could result in
clutch damage.
CAUTION! (Continued)

Maximum Recommended Downshift Speeds
CAUTION!
Failure to follow the maximum
recommended downshifting speeds may
cause the engine to overspeed and/or
damage the clutch disc, even if the clutch
pedal is pressed.
Manual Transmission Downshift Speeds in MPH (KM/H)
Gear Selection 6 to 55 to 44 to 33 to 22 to 1
Maximum Speed 80 (129) 70 (113)50 (81)30 (48)15 (24)
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
downshifting or downshifting at too high of
a vehicle speed even if the clutch pedal is
held pressed (i.e., not released).

STARTING AND OPERATING
148
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 gear selector provides
PARK, REVERSE, NEUTRAL, DRIVE, and
MANUAL (AutoStick) shift positions. Manual
shifts can be made using the AutoStick shift
control. Moving the gear selector into the
MANUAL (-/+) position (beside the DRIVE
position) activates AutoStick mode,
providing manual shift control and displaying
the current gear in the instrument cluster (as
1, 2, 3, etc.). Toggling the gear selector
forward (-) or rearward (+) while in the
MANUAL position will manually select the
transmission gear.
Refer to “AutoStick” 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
MANUAL (AutoStick, (+/-)) position (beside
the DRIVE position). In MANUAL (AutoStick)
mode, the transmission gear (1, 2, 3, etc.) isdisplayed in the instrument cluster. Move
the gear selector to the right (into the DRIVE
[D] position) for access to PARK, REVERSE,
and NEUTRAL.
Gear Selector
Gear Ranges
Do not depress the accelerator pedal when
shifting from PARK or NEUTRAL into
another gear range.
NOTE:
After selecting any gear range, wait a
moment to allow the selected gear to engage
before accelerating. This is especially
important when the engine is cold.
AUTOSTICK
AutoStick is a driver-interactive transmission
feature providing manual shift control, giving
you more control of the vehicle. AutoStick
allows you to maximize engine braking, elim -
inate undesirable upshifts and downshifts,
and improve overall vehicle performance.
This system can also provide you with more
control during passing, city driving, cold slip -
pery conditions, mountain driving, trailer
towing and many other situations.
Operation
When the gear selector is in the AutoStick
position (beside the DRIVE position), it can
be moved forward and rearward. This allows
the driver to manually select the transmis -
sion gear being used. Moving the gear
selector forward (-) triggers a downshift, and
rearward (+) an upshift. The current gear is
displayed in the instrument cluster.

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 50 mph
(80 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.
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 (N)
This range disengages the driveline from the
powertrain.
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.
2-Speed 4x4 Switch (With Rear Lock)
NOTE:
If shift conditions/interlocks are not met, a
message will flash from the instrument
cluster display with instructions on how to
complete the requested shift.
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
driveshafts from the powertrain and will
allow the vehicle to roll, even if the
automatic transmission is in PARK (P) (or
manual transmission is in gear). The
parking brake should always be applied
when the driver is not in the vehicle.
