2018 JEEP WRANGLER UNLIMITED wheel

Push the SWAY BAR switch to activate the
system. Push the switch again to deactivate
the system. The “Sway Bar Indicator Light”
(located in the instrument cluster) will illumi-
nate when the bar is disconnected. The
“Sway Bar Indicator Light” will flash during
activation transition, or when activation con-
ditions are not met. The stabilizer/sway bar
should remain in on-road mode during nor-
mal driving conditions.
WARNING!
Ensure the stabilizer/sway bar is recon-
nected before driving on hard surfaced
roads or at speeds above 18 mph
(29 km/h); a disconnected stabilizer/sway
bar may contribute to the loss of vehicle
control, which could result in serious in-
jury. Under certain circumstances, the
front stabilizer/sway bar enhances vehicle
stability and assists with vehicle control.
The system monitors vehicle speed and
will attempt to reconnect the stabilizer/
sway bar at speeds over 18 mph
(29 km/h). This is indicated by a flashing
or solid “Sway Bar Indicator Light.” Once
WARNING!
vehicle speed is reduced below 14 mph
(22 km/h), the system will once again
attempt to return to off-road mode.
To disconnect the stabilizer/sway bar, shift to
either 4H or 4L and push the SWAY BAR
switch to obtain the off-road position. Refer
to “Four-Wheel Drive Operation” in this sec-
tion for further information. The “Sway Bar
Indicator Light” will flash until the stabilizer/
sway bar has been fully disconnected.
NOTE:
The stabilizer/sway bar may be torque locked
due to left and right suspension height differ-
ences. This condition is due to driving sur-
face differences or vehicle loading. In order
for the stabilizer/sway bar to disconnect/
reconnect, the right and left halves of the bar
must be aligned. This alignment may require
that the vehicle be driven onto level ground or
rocked from side to side.
To return to on-road mode, push the SWAY
BAR switch again.
WARNING!
If the stabilizer/sway bar will not return to
on-road mode, the “Sway Bar Indicator
Light” will flash in the instrument cluster
and vehicle stability may be reduced. Do
not attempt to drive the vehicle over
18 mph (29 km/h). Driving faster than
18 mph (29 km/h) with a disconnected
stabilizer/sway bar may contribute to the
loss of vehicle control, which could result
in serious injury.
STOP/START SYSTEM —
AUTOMATIC
TRANSMISSION (IF
EQUIPPED)
The Stop/Start function is developed to re-
duce fuel consumption. The system will stop
the engine automatically during a vehicle
stop if the required conditions are met. Re-
leasing the brake pedal or pressing the accel-
erator pedal will automatically re-start the
engine.
157

Other Factors Which Can Inhibit Autostop In-
clude:
• Accelerator pedal input.
• Vehicle speed threshold not achieved from
previous auto-stop.
• Steering angle beyond threshold. (ESS
Models Only)
• ACC is on and speed is set.
• Vehicle is at high altitude.
• System fault present.
It may be possible for the vehicle to be driven
several times without the STOP/START sys-
tem going into a STOP/START READY state
under more extreme conditions of the items
listed above.
To Start The Engine While In Autostop
Mode
While in a forward gear, the engine will start
when the brake pedal is released or the
throttle pedal is depressed. The transmission
will automatically re-engage upon engine re-
start.Conditions That Will Cause The Engine To Start
Automatically While In Autostop Mode:
• The transmission selector is moved out of
DRIVE.
• To maintain cabin temperature comfort.
• Actual cabin temperature is significantly
different than temperature set on Auto
HVAC.
• HVAC is set to full defrost mode.
• HVAC system temperature or fan speed is
manually adjusted.
• Battery voltage drops too low.
• Low brake vacuum (e.g. after several brake
pedal applications).
• STOP/START OFF switch is pushed.
• A STOP/START system error occurs.
• STOP/START AUTO STOP ACTIVE time ex-
ceeds 5 minutes.
• 4WD system is put into 4LO or Neutral
mode.
• Steering wheel is turned beyond threshold.
(ESS Models Only)
To Manually Turn Off The Stop/Start
System
1. Push the STOP/START OFF switch (lo-
cated on the switch bank). The light on
the switch will illuminate.
2. The “STOP/START OFF” message will ap-
pear in instrument cluster display within
the Stop/Start section. Refer to “Instru-
ment Cluster” in “Getting To Know Your
Instrument Panel” in your Owner’s
Manual for further information.

3. At the next vehicle stop (after turning off
the STOP/START system), the engine will
not be stopped.
4. The STOP/START system will reset itself
back to an ON condition every time the
ignition is turned off and back on.
To Manually Turn On The Stop/Start
System
Push the STOP/START OFF switch (located
on the switch bank). The light on the switch
will turn off.
For complete details on the Stop/Start Sys-
tem refer to the “Stop/Start System” in the
“Starting And Operating” section located in
your Owner’s Manual for further information.
System Malfunction
If there is a malfunction in the STOP/START
system, the system will not shut down the
engine. A “SERVICE STOP/START SYSTEM”
message will appear in the instrument cluster
display. Refer to “Instrument Cluster Dis-
play“ in “Getting to Know Your Instrument
Panel” for further information.
If the “SERVICE STOP/START SYSTEM”
message appears in the instrument cluster
display, have the system checked by an au-
thorized dealer.
SPEED CONTROL
When engaged, the Speed Control takes over
accelerator operations at speeds greater than
20 mph (32 km/h).
The Speed Control buttons are located on the
right side of the steering wheel.
Speed Control Buttons
1 — CANC/Cancel
2 — On/Off

PARKVIEW REAR BACK UP
CAMERA — IF EQUIPPED
The ParkView Rear Back Up Camera allows
you to see an on-screen image of the rear
surroundings of your vehicle whenever the
gear selector is put into REVERSE. The image
will be displayed in the touchscreen display
along with a caution note to “check entire
surroundings” across the top of the screen.
After five seconds this note will disappear.
The ParkView camera is located on the rear of
the vehicle in the center of the spare tire.
Manual Activation Of The Rear View Camera
1. Press the “Controls” button located on
the bottom of the Uconnect display.
2. Press the “Backup Camera” button to
turn the Rear View Camera system on.
NOTE:
The ParkView Rear Back Up Camera has
programmable modes of operation that may
be selected through the Uconnect System.
Refer to “Uconnect Settings” in “Multime-
dia” in your Owner’s Manual for further infor-
mation.When the vehicle is shifted out of REVERSE
(with camera delay turned off), the rear cam-
era mode is exited and the previous screen
appears again. When the vehicle is shifted
out of REVERSE (with camera delay turned
on), the camera image will continue to be
displayed for up to ten seconds after shifting
out of REVERSE unless the vehicle speed
exceeds 8 mph (13 km/h), the vehicle is
shifted into PARK, the vehicle’s ignition is
cycled to the OFF position, or the user
presses image defeat [X] to exit out of the
camera video display.
NOTE:
• If the vehicle speed remains below 8 mph
(13 km/h), the Rear View Camera image will
be displayed continuously until deactivated
via the touchscreen button “X”, the vehicle
is shifted into PARK, or the ignition is
placed in the OFF position.
• The touchscreen button “X” to disable dis-
play of the camera image is made available
ONLY when the vehicle is not in REVERSE.
When enabled, active guide lines are overlaid
on the image to illustrate the width of the
vehicle and its projected backup path basedon the steering wheel position. A dashed
center line overlay indicates the center of the
vehicle to assist with parking or aligning to a
hitch/receiver.
When enabled, fixed guide lines are overlaid
on the image to illustrate the width of the
vehicle.
Different colored zones indicate the distance
to the rear of the vehicle.
WARNING!
Drivers must be careful when backing up
even when using the ParkView Rear Back
Up Camera. Always check carefully behind
your vehicle, and be sure to check for
pedestrians, animals, other vehicles, ob-
structions, or blind spots before backing
up. You are responsible for the safety of
your surroundings and must continue to
pay attention while backing up. Failure to
do so can result in serious injury or death.
