the primary method by which the driver shifts the
vehicle into PARK.
The conditions under which AutoPark will engage
are outlined on the following pages.
WARNING!
Driver inattention could lead to failure to place
the vehicle in PARK. ALWAYS DO A VISUAL
CHECK that your vehicle is in PARK by verifying
that a solid (not blinking) “P” is indicated in
the instrument cluster display and on the gear
selector. If the "P" indicator is blinking, your
vehicle is not in PARK. As an added precau -
tion, always apply the parking brake when
exiting the vehicle.
AutoPark is a supplemental feature. It is not
designed to replace the need to shift your
vehicle into PARK. It is a back-up system and
should not be relied upon as the primary
method by which the driver shifts the vehicle
into PARK.

23_WL_OM_EN_USC_t.book Page 120

STARTING AND OPERATING125
AUTO PARK BRAKE
The EPB can be programmed to be applied
automatically whenever the vehicle is at a
standstill and the transmission is placed in PARK.
Auto Park Brake is enabled and disabled by
customer selection through the customer
programmable features section of the Uconnect
Settings Úpage 218.
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.
SAFEHOLD
SafeHold is a safety feature of the EPB system that
will place the transmission in PARK, and engage
the parking brake automatically if the vehicle is left
unsecured while the ignition is in ON/RUN.
The parking brake will automatically engage if all of
the following conditions are met:
The vehicle is at a standstill.
There is no attempt to press the brake pedal or
accelerator pedal.
The seat belt is unbuckled.
The driver door is open. SafeHold can be temporarily bypassed by pushing
the EPB switch while the driver door is open. Once
manually bypassed, 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.
HOLD ‘N GO — IF EQUIPPED
Hold ‘N Go is a comfort feature that allows the
driver to remove their foot from the brake pedal
once the vehicle has come to a stop. The vehicle
must be held at a standstill for a predetermined
amount of time by hydraulic braking. The EPB will
then engage and continue to hold the vehicle at a
stop until the driver applies the accelerator pedal.
Hold ‘N Go can be activated or deactivated by
pushing the HOLD button located on the switch
bank.

HOLD Switch
The following conditions must be met for Hold ‘N
Go 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.

STARTING AND OPERATING137
Normal Ride Height (NRH) 0.0 inches (0 mm) –
This is the standard position of the suspension
and is meant for normal driving.
Aero Height (Lowers the vehicle approximately
-0.8 inches [-21 mm] Front and -1.0 inches
[-25 mm] Rear) – This position provides
improved aerodynamics by lowering the vehicle.
The vehicle will automatically enter Aero 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
NRH from Aero 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, regardless of vehicle
speed if the vehicle is in SPORT mode.
Entry/Exit Height (Lowers the vehicle approxi -
mately -1.8 inches [-46 mm] Front and
-2.0 inches [-50 mm] Rear) – 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, push the DOWN
button twice from NRH while the vehicle speed
is below 4 mph (6 km/h). To exit Entry/Exit,
push the UP button twice while in Entry/Exit or
drive the vehicle over 6 mph (10 km/h).
NOTE:Automatic lowering of the vehicle into Entry/Exit
can be enabled through the Uconnect Touch -
screen Radio by selecting the “Auto Entry/Exit”
setting. 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 to Entry/Exit height if the air suspension level
is in OR2 or OR1. If the vehicle is equipped with
Intrusion Theft Module (ITM), the lowering will be
suppressed when the ignition is switched OFF and
the door is open to prevent setting the alarm off.
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
Ú page 134.
The system requires that the engine be running for
all changes. When lowering the vehicle all of the
doors 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
Ú
page 204.
Default Ride Height
Select Aero Height or Normal Ride Height as the
default for all vehicle speeds and operation.
This is the selected height that the suspension
will level for speed changes (e.g. raising from
Entry/Exit Height at speed, lowering from Off
Road Height at speed, etc.).
Default ride height can be changed by manually
adjusting the ride height switch to Normal Ride
Height or Aero Height and staying in the
selected height for 2.5 seconds. It will be stored
as the default ride height and the height will be
maintained until a new default ride height is
selected.
If equipped with a touchscreen radio, all enabling/
disabling of air suspension features must be done
through the radio Ú page 204.

FUEL SAVER TECHNOLOGY 5.7L ONLY —
IF EQUIPPED
This feature offers improved fuel economy by
shutting off four of the engine's eight cylinders
during light load and cruise conditions. The system
is automatic with no driver inputs or additional
driving skills required.
NOTE:This system may take some time to return to full
functionality after a battery disconnect.
POWER STEERING
The electric power steering system provides
enhanced vehicle response and increased ease of
maneuverability in tight spaces. The power
steering system adapts to different driving
conditions. If the electric power steering system
experiences a fault that prevents it from providing
assistance, you will still have the ability to steer the
vehicle manually.
NOTE:Alternate electric power steering efforts (Normal,
Comfort and Sport) can be selected through the
Uconnect System Ú page 204. If SPORT mode is
selected, steering efforts are optimized for sporty
driving.
If the Electric Power Steering warning
icon is displayed and the “Service Power
Steering” or the “Power Steering Assist
Off – Service System” message is
displayed within the instrument cluster display,
this indicates the vehicle needs to be taken to the
dealer for service Ú page 108.
NOTE:
Even if the power steering assistance is no
longer operational, it is still possible to steer the
vehicle. Under these conditions there will be a
substantial increase in steering effort, espe -
cially at low speeds and during parking maneu -
vers.
If the condition persists, see an authorized
dealer for service.
WARNING!
Continued operation with reduced assist could
pose a safety risk to yourself and others. Service
should be obtained as soon as possible.
