NOTE:
• If shift conditions/interlocks are not met,or a transfer case motor temperature pro-
tection condition exists, a “For 4x4 High
Slow Below 3 mph (5 km/h) Put Trans in N
push 4 Low” message will flash from the
instrument cluster display. Refer to “In-
strument Cluster Display” in “Getting To
Know Your Instrument Panel” for further
information.
• Shifting into or out of 4WD LOW is pos- sible 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.Shifting Into NEUTRAL (N)

Quadra-Drive II System — If Equipped
The optional Quadra-Drive II System features
two torque transfer couplings. The couplings
include an Electronic Limited-Slip Differen-
tial (ELSD) rear axle and the Quadra-Trac II
transfer case. The optional ELSD axle is fully
automatic and requires no driver input to
operate. Under normal driving conditions,
the unit functions as a standard axle, balanc-
ing 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 auto-
matically 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 shift-
ing information, preceding this section, for
shifting this system.

further information.
Operation
The indicator lamps 3 through 6 will illumi-
nate to show the current position of the
vehicle. Flashing indicator lamps will show a
position which the system is working to

168

achieve. When raising, if multiple indicator
lamps are flashing on the “Up” button, the
highest flashing indicator lamp is the posi-
tion the system is working to achieve. When
lowering, if multiple indicators are flashing
on the "Up" button the lowest solid indicator
lamp is the position the system is working to
achieve.
Pushing the “UP” button once will move the
suspension one position higher from the cur-
rent position, assuming all conditions are
met (i.e. engine running, speed below thresh-
old, etc). The “UP” button can be pushed
multiple times, each push will raise the re-
quested level by one position up to a maxi-
mum position of OR2 or the highest position
allowed based on current conditions (i.e. ve-
hicle speed, etc).
Pushing the “DOWN” button once will move
the suspension one position lower from the
current level, assuming all conditions are met
(i.e. engine running, doors closed, speed be-
low threshold, etc). The “DOWN” button can
be pressed multiple times. Each push will
lower the requested level by one positiondown to a minimum of Park Mode or the
lowest position allowed based on current con-
ditions (i.e. vehicle speed, etc.)
Automatic height changes will occur based
on vehicle speed and the current vehicle
height. The indicator lamps and instrument
cluster display messages will operate the
same for automatic changes and user re-
quested changes.
• Off-Road 2 (OR2) – Indicator lamps 4, 5,
and 6 will be illuminated when the vehicle
is in OR2.
• Off-Road 1 (OR1) – Indicator lamps 4 and 5 will be illuminated when the vehicle is in
OR1.
• Normal Ride Height (NRH) – Indicator lamp 4 will be illuminated when the ve-
hicle is in this position.
• Entry/Exit Mode – Indicator lamp 3 will be illuminated when the vehicle is in Entry/
Exit Mode. If Entry/Exit Mode is requested
while vehicle speed is between 15 mph
(24 km/h) and 25 mph (40 km/h), indica-
tor lamp 4 will remain on solid and indi-
cator lamp 3 will flash as the system waits
for the vehicle to reduce speed. If vehicle speed is reduced to, and kept below,
15 mph (24 km/h) indicator lamp 4 will
turn off and indicator lamp 3 will flash
until Entry/Exit Mode is achieved at which
point indicator lamp 3 will go solid. If
during the height change to Entry/Exit
Mode, the vehicle speed exceeds 15 mph
(24 km/h), the height change will be
paused until the vehicle speed either goes
below 15 mph (24 km/h) and the height
change continues to Entry/Exit Mode, or
exceeds 25 mph (40 km/h) and the ve-
hicle height will return to NRH. Entry/Exit
Mode may be selected while the vehicle is
not moving provided that the engine is still
running and all doors remain closed.
• Transport Mode - No indicator lamps will be illuminated. Customer driving will dis-
able Transport Mode.
• Tire/Jack Mode - indicator lamps 3 and 6 will be illuminated. Customer driving
will disable Tire/Jack Mode.
• Wheel Alignment Mode - indicator lamps 3 and 4 will be illuminated. Customer
driving will disable Wheel Alignment
Mode.

• The ACC system applies the brake down toa full stop when following a target vehicle.
If an ACC host vehicle follows a target
vehicle to a standstill, the host vehicle will
release the vehicle brakes two seconds
after coming to a full stop.
• The ACC system maintains set speed when driving up hill and down hill. However, a
slight speed change on moderate hills is
normal. In addition, downshifting may oc-
cur while climbing uphill or descending
downhill. This is normal operation and
necessary to maintain set speed. When
driving up hill and down hill, the ACC
system will cancel if the braking tempera-
ture exceeds normal range (overheated).

WARNING!
Adaptive Cruise Control (ACC) is a conve-
nience system. It is not a substitute for
active driving involvement. It is always the
driver’s responsibility to be attentive of
road, traffic, and weather conditions, ve-
hicle speed, distance to the vehicle ahead;
and, most importantly, brake operation to
ensure safe operation of the vehicle under
all road conditions. Your complete atten-
tion is always required while driving to
maintain safe control of your vehicle. Fail-
ure to follow these warnings can result in a
collision and death or serious personal
injury.
The ACC system:
• Does not react to pedestrians, oncoming vehicles, and stationary objects (e.g., a
WARNING!
stopped vehicle in a traffic jam or a
disabled vehicle).
• Cannot take street, traffic, and weather
conditions into account, and may be
limited upon adverse sight distance con-
ditions.
• Does not always fully recognize complex
driving conditions, which can result in
wrong or missing distance warnings.
• Will bring the vehicle to a complete stop
while following a target vehicle and hold
the vehicle for 2 seconds in the stop
position. If the target vehicle does not
start moving within two seconds the ACC
system will display a message that the
system will release the brakes and that
the brakes must be applied manually. An
audible chime will sound when the
brakes are released.
You should switch off the ACC system:
• When driving in fog, heavy rain, heavy
snow, sleet, heavy traffic, and complex
driving situations (i.e., in highway con-
struction zones).
WARNING!
• When entering a turn lane or highway offramp; when driving on roads that are
winding, icy, snow-covered, slippery, or
have steep uphill or downhill slopes.
• When towing a trailer up or down steep
slopes.
• When circumstances do not allow safe
driving at a constant speed.
The Cruise Control system has two control
modes:
• Adaptive Cruise Control mode for main-
taining an appropriate distance between
vehicles.
• Normal (fixed speed) electronic speed
control mode for cruising at a constant
preset speed. For additional informa-
tion, refer to “Normal (Fixed Speed)
Cruise Control Mode” in your Owner’s
Manual at
www.jeep.com/en/owners/manuals/
Normal (fixed speed) electronic speed con-
trol will not react to preceding vehicles. Al-
ways be aware of the mode selected.
You can change the mode by using the
Cruise Control buttons. The two control
