STARTING AND OPERATING125
(Continued)
The following conditions must be met for Auto Hold to
activate:

Driver’s door is closed
 Driver's seat belt is fastened
 Vehicle is at a standstill
 Forward gear is selected
 ACC is not engaged
 EPB is not applied
 ParkSense Active Park Assist System auto parking
maneuver is not activated
Brake Maintenance Mode
We recommend having your brakes serviced by an
authorized dealer. You should only make repairs for which
you have the knowledge and the right equipment. You
should only enter Brake Maintenance mode during brake
service.
When servicing your rear brakes, it may be necessary for
you or your technician to push the rear piston into the rear
caliper bore. With the EPB system, this can only be done
after retracting the EPB actuator. Fortunately, actuator
retraction can be done easily by entering the Brake
Maintenance mode through the Uconnect Settings in your
vehicle. This menu-based system will guide you through
the steps necessary to retract the EPB actuator in order to
perform rear brake service. Maintenance mode has requirements that must be met in
order to be activated:

The vehicle must be at a standstill.
 The parking brake must be unapplied.
 The transmission must be in PARK or NEUTRAL.
While in Maintenance mode, the EPB Warning Light will
flash continuously while the ignition is ON.
When brake service work is complete, the following steps
must be followed to reset the parking brake system to
normal operation:
 Ensure the vehicle is at a standstill.
 Press the brake pedal with moderate force.
 Apply the EPB switch.
AUTOMATIC TRANSMISSION
You must press and hold the brake pedal while shifting out
of PARK.
WARNING!
You can be badly injured working on or around a motor
vehicle. Do only that service work for which you have
the knowledge and the right equipment. If you have any
doubt about your ability to perform a service job, take
your vehicle to a competent mechanic.
WARNING!
Never use the PARK (P) position as a substitute for
the parking brake. Always apply the parking brake
fully when exiting the vehicle 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 trans -
mission gear selector out of PARK with the brake
pedal released. Make sure the transmission is in
PARK before exiting the vehicle.
 The transmission may not engage PARK if the vehicle
is moving. Always bring the vehicle to a complete
stop before shifting to PARK, and verify that the
transmission gear position indicator solidly indicates
PARK without blinking. Ensure that the vehicle is
completely stopped, and the PARK position is prop -
erly indicated, before exiting the vehicle.
 It is dangerous to shift out of PARK or NEUTRAL (N) 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 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.

128STARTING AND OPERATING
NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. Apply the parking brake
and shift the transmission into PARK (P) if you must exit
the vehicle.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission
automatically upshifts through all forward gears. When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading
conditions, in hilly terrain, traveling into strong head
winds, or while towing a heavy trailer), use the Electronic
Range Select (ERS) shift control to select a lower gear
Úpage 129. Under these conditions, using a lower gear
will improve performance and extend transmission life by
reducing excessive shifting and heat build-up.
During cold temperatures, transmission operation may be
modified depending on engine and transmission
temperature as well as vehicle speed. This feature
improves warm-up time of the engine and transmission to
achieve maximum efficiency. Engagement of the torque
converter clutch is inhibited until the transmission fluid is
warm. Normal operation will resume once the
transmission temperature has risen to a suitable level.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
mode is activated. In this mode, the transmission may
operate only in certain gears, or may not shift at all.
Vehicle performance may be severely degraded and the
engine may stall. In some situations, the transmission may
not re-engage if the engine is turned off and restarted. The
Malfunction Indicator Light (MIL) may be illuminated. A
message in the instrument cluster will inform the driver of
the more serious conditions, and indicate what actions
may be necessary. In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
NOTE:In cases where the instrument cluster message indicates
the transmission may not re-engage after engine
shutdown, perform this procedure only in a desired
location (preferably, at an authorized dealer).

1. Stop the vehicle.

2. Shift the transmission into PARK (P), if possible.
If not, shift the transmission to NEUTRAL (N).
3. Push and hold the ignition switch until the engine turns off.
4. Wait approximately 30 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 recommend that
you visit an authorized dealer at your earliest possible
convenience. An authorized dealer has diagnostic
equipment to assess the condition of your transmission.
If the transmission cannot be reset, authorized dealer
service is required.
WARNING!
Do not coast in NEUTRAL and never turn off the ignition
to coast down a hill. These are unsafe practices that
limit your response to changing traffic or road
conditions. You might lose control of the vehicle and
have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage.

STARTING AND OPERATING129
Electronic Range Select (ERS) Operation
The ERS shift control allows the driver to limit the highest
available gear when the transmission is in DRIVE and ERS
mode is not active. For example, if you set the
transmission gear limit to FOURTH gear, the transmission
will not shift above FOURTH gear (except to prevent engine
overspeed), but will shift through the lower gears normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the transmission gear selector is in
DRIVE, the transmission will operate automatically,
shifting between all available gears. Tapping the “-” button
(on the steering wheel) will activate ERS mode, display the
current gear in the instrument cluster, and set that gear as
the top available gear. Once in ERS mode, tapping the “-”
or “+” button will change the top available gear.

Electronic Range Select (ERS)

To exit ERS mode, simply push and hold the “+” button
until the gear limit display disappears from the instrument
cluster.
When to Use TOW/HAUL Mode
Select TOW/HAUL mode when driving in conditions such
as: driving in hilly areas, towing a trailer, carrying a heavy
load, etc. This mode will improve performance and reduce
the potential for transmission overheating or failure due to
excessive shifting.

TOW/HAUL Switch

The TOW/HAUL Indicator Light will illuminate in the
instrument cluster to indicate that TOW/HAUL mode has
been activated. Pushing the switch a second time restores
normal operation. Normal operation is always the default
at engine start-up. If TOW/HAUL mode is desired, the
switch must be pushed each time the engine is started.
FOUR-WHEEL DRIVE OPERATION
QUADRA-TRAC I OPERATING
I
NSTRUCTIONS/PRECAUTIONS —
I
F EQUIPPED
The Quadra-Trac I is a single-speed (HI range only) transfer
case, which provides convenient full-time four-wheel drive.
No driver interaction is required. The Brake Traction
Control (BTC) System, which combines standard ABS and
Traction Control, provides resistance to any wheel that is
slipping to allow additional torque transfer to wheels with
traction.
NOTE:The Quadra-Trac I system is not appropriate for conditions
where 4WD LOW range is recommended Úpage 193.
1 — Shift Up “+”
2 — Shift Down “–”
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their grip
and the vehicle could skid, causing a collision or
personal injury.
WARNING!
Do not use the “TOW/HAUL” feature when driving in icy
or slippery conditions. The increased engine braking
can cause the rear wheels to slide, and the vehicle to
swing around with the possible loss of vehicle control,
which may cause an accident possibly resulting in
personal injury or death.

130STARTING AND OPERATING
QUADRA-TRAC II OPERATING
I
NSTRUCTIONS/PRECAUTIONS —
I
F EQUIPPED
The Quadra-Trac II transfer case is fully automatic in the
normal driving 4WD HI mode. The Quadra-Trac II transfer
case provides three positions:
 4WD HI
 N (Neutral)
 4WD LOW
When additional traction is required, the 4WD LOW
position can be used for increased torque at the wheels.
Driving in the 4WD LOW position 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 4WD HI
position 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
damage to the transfer case.
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
four-wheel drive system mode position, see the following
information:
4WD HI
This range is the default operating mode for daily use.
N (NEUTRAL)
This range disengages the driveline from the powertrain. It
is used for towing your vehicle behind another vehicle
Úpage 190.
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. Do not exceed 25 mph (40 km/h).
SHIFTING PROCEDURES
4WD HI To 4WD LOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the
ignition switch in the ON position or the engine running,
shift the transmission into NEUTRAL (N), and push and
hold the 4WD LOW button once on the transfer case
switch until the 4WD LOW indicator light begins to flash in
the instrument cluster.
WARNING!
You or others could be injured or killed if you leave the
vehicle unattended with the transfer case in the N
(Neutral) position without first fully engaging the
parking brake. The transfer case N (Neutral) 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.
WARNING!
You or others could be injured or killed if you leave the
vehicle unattended with the transfer case in the N
(Neutral) position without first fully engaging the
parking brake. The transfer case N (Neutral) 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.

23_WS_OM_EN_USC_t.book Page 130

STARTING AND OPERATING131
The 4WD LOW light will remain on solid when the shift is
complete.

4WD LOW Button

NOTE:If shift conditions/interlocks are not met a message will
show on the instrument cluster display with instructions
required to complete the shift
Úpage 99.
4WD LOW To 4WD HI
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the
ignition switch in the ON position or the engine running,
shift the transmission into NEUTRAL (N), and push the
4WD LOW button once on the transfer case switch until
the 4WD LOW indicator light begins to flash in the
instrument cluster. The 4WD LOW light will go out when
the shift is complete.
NOTE:
If shift conditions/interlocks are not met a message
will show on the instrument cluster display with instruc -
tions required to complete the shift
Úpage 99.
 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 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 transfer case will not allow the
shift.
QUADRA-DRIVE II SYSTEM —
I
F EQUIPPED
The Quadra-Drive II System features two torque transfer
couplings. The couplings include an Electronic
Limited-Slip Differential (ELSD) rear axle and the
Quadra-Trac II transfer case. The ELSD axle is fully
automatic and requires no driver input to operate. Under
normal driving conditions, the unit functions as a standard
axle, balancing torque evenly between left and right
wheels. With a traction difference between left and right
wheels, the coupling will sense a speed difference. As one
wheel begins to spin faster than the other, torque will
automatically transfer from the wheel that has less
traction, to the wheel that has traction. While the transfer
case and axle coupling differ in design, their operation is
similar. Follow the Quadra-Trac II transfer case shifting
information, preceding this section, for shifting this
system.
SELEC-TERRAIN — IF EQUIPPED
SELEC-TERRAIN MODE SELECTION
Selec-Terrain combines the capabilities of the vehicle
control systems, along with driver input, to provide the

Normal Ride Height (NRH) – This is the standard posi -
tion of the suspension and is meant for normal driving.
 Off-Road 1 (OR1) (Raises the vehicle approximately
1.2 inches [30 mm]) – This is the primary position for
all off-road driving until OR2 is needed. A smoother and
more comfortable ride will result. Push the toggle
switch forward once from the NRH position while the
vehicle speed is below 38 mph (61 km/h). When in the
OR1 position, if the vehicle speed remains between
40 mph (64 km/h) and 50 mph (80 km/h) for greater than 20 seconds or if the vehicle speed exceeds
50 mph (80 km/h), the vehicle will be automatically
lowered to NRH
Úpage 193. OR1 is unavailable on
4x2 air suspension vehicles.
 Off-Road 2 (OR2) (Raises the vehicle approximately
2.0 inches [51 mm]) – This position is intended for
off-roading use only where maximum ground clearance
is required. To enter OR2, push the toggle switch
forward twice from the NRH position or once from the
OR1 position while vehicle speed is below 20 mph
(32 km/h). While in OR2, if the vehicle speed exceeds
25 mph (40 km/h) the vehicle height will be automati -
cally lowered to OR1
Úpage 193. OR2 is unavailable
on 4x2 air suspension vehicles.
 Aero Height (Lowers the vehicle approximately
-0.6 inches [-15 mm]) – This position provides
improved aerodynamics by lowering the vehicle. The
vehicle will automatically enter Aero Height when the
vehicle speed remains between 62 mph (100 km/h)
and 66 mph (106 km/h) for greater than 20 seconds
or if the vehicle speed exceeds 66 mph (106 km/h). The vehicle will return to Default Ride Height from Aero
Height if the vehicle speed remains between 30 mph
(48 km/h) and 35 mph (56 km/h) for greater than
20 seconds or if the vehicle speed falls below 30 mph
(48 km/h). The vehicle will enter Aero Height, regard
-
less of vehicle speed if the vehicle is in “SPORT” mode.
 Entry/Exit Height (Lowers the vehicle approximately
-1.6 inches [-40 mm]) – This position lowers the
vehicle for easier passenger entry and exit as well as
lowering the rear of the vehicle for easier loading and
unloading of cargo. To enter Entry/Exit Height, push the
toggle switch down twice from NRH while the vehicle
speed is below 6 mph (10 km/h). To exit Entry/Exit
Height, push the UP button once while in Entry/Exit
Height or drive the vehicle over 4 mph (6 km/h).
NOTE:Automatic lowering of the vehicle into Entry/Exit Height
can be enabled through the Uconnect Touchscreen Radio.
If this feature is enabled, the vehicle will only lower if the
gear selector is in PARK, the terrain switch is in AUTO, the
transfer case is in AUTO and the vehicle level is either in
Normal or Aero Height. The vehicle will not automatically
lower if the air suspension level is in OR2 or OR1. When
towing, the automatic Entry/Exit feature may be disabled
through the Uconnect Touchscreen Radio to prevent
vehicle and trailer movement when gear selector is moved
to PARK. The Selec-Terrain system will automatically change the
vehicle to the proper height based on the position of the
Selec-Terrain switch. The height can be changed from the
default Selec-Terrain setting by normal use of the air
suspension buttons
Úpage 131.
The system requires that the engine be running for all
changes. When lowering the vehicle all of the doors,
including the liftgate, must be closed. If a door is opened
at any time while the vehicle is lowering the change will not
be completed until the open door(s) is/are closed.
The Quadra-Lift Air Suspension system uses a lifting and
lowering pattern which keeps the headlights from
incorrectly shining into oncoming traffic. When raising the
vehicle, the rear of the vehicle will move up first and then
the front. When lowering the vehicle, the front will move
down first and then the rear.
After the engine is turned off, it may be noticed that the air
suspension system operates briefly; this is normal. The
system is correcting the position of the vehicle to ensure a
proper appearance.
To assist with changing a spare tire, the Quadra-Lift Air
Suspension system has a feature which allows the
automatic leveling to be disabled
