2019 JEEP WRANGLER UNLIMITED ECO mode

Beginning with the next ignition cycle, the
TPMS will no longer chime or display the
“SERVICE TIRE PRESSURE SYSTEM” mes-
sage in the instrument cluster but dashes (--)
will remain in place of the pressure values.
To reactivate the TPMS, replace all four
wheel and tire assemblies (road tires) with
tires equipped with TPMS sensors. Then,
drive the vehicle for up to 10 minutes above
15 mph (24 km/h). The TPMS will chime, the
TPMS Warning Light will flash on and off for
75 seconds and then turn off. The instrument
cluster will display the “SERVICE TIRE
PRESSURE SYSTEM” message and then dis-
play pressure values in place of the dashes.
On the next ignition cycle the "SERVICE TIRE
PRESSURE SYSTEM" message will no longer
be displayed as long as no system fault exists.
OCCUPANT RESTRAINT
SYSTEMS
Some of the most important safety features in
your vehicle are the restraint systems:
Occupant Restraint Systems Features
• Seat Belt Systems
• Supplemental Restraint Systems (SRS) Air
Bags
• Child Restraints
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on
others. If you are not sure, ask an authorized
dealer.
Important Safety Precautions
Please pay close attention to the information
in this section. It tells you how to use your
restraint system properly, to keep you and
your passengers as safe as possible.
Here are some simple steps you can take to
minimize the risk of harm from a deploying
air bag:
1. Children 12 years old and under should
always ride buckled up in the rear seat of
a vehicle with a rear seat.2. A child who is not big enough to wear the
vehicle seat belt properly (Refer to “Child
Restraints” in this section for further in-
formation) must be secured in the appro-
priate child restraint or belt-positioning
booster seat in a rear seating position.
3. If a child from 2 to 12 years old (not in a
rear-facing child restraint) must ride in
the front passenger seat, move the seat asWarning Label On Front Passenger Sun

retractor can be “switched” into a locked
mode by pulling all of the webbing out of the
retractor and then letting the webbing retract
back into the retractor. If it is locked, the ALR
will make a clicking noise while the webbing
is pulled back into the retractor. Refer to the
“Automatic Locking Mode” description in
“Switchable Automatic Locking Retractors
(ALR)” under “Occupant Restraint Systems”
for additional information on ALR.
Installing A Child Restraint With A Switch-
able Automatic Locking Retractor (ALR)
Child restraint systems are designed to be
secured in vehicle seats by lap belts or the lap
belt portion of a lap/shoulder belt.
WARNING!
• Improper installation or failure to prop-
erly secure a child restraint can lead to
failure of the restraint. The child could
be badly injured or killed.
• Follow the child restraint manufacturer’s
directions exactly when installing an in-
fant or child restraint.1. Place the child seat in the center of the
seating position. For some second row
seats, you may need to recline the seat
and/or raise the head restraint (if adjust-
able) to get a better fit. If the rear seat can
be moved forward and rearward in the
vehicle, you may wish to move it to its
rear-most position to make room for the
child seat. You may also move the front
seat forward to allow more room for the
child seat.
2. Pull enough of the seat belt webbing from
the retractor to pass it through the belt
path of the child restraint. Do not twist the
belt webbing in the belt path.
3. Slide the latch plate into the buckle until
you hear a “click.”
4. Pull on the webbing to make the lap
portion tight against the child seat.
5. To lock the seat belt, pull down on the
shoulder part of the belt until you have
pulled all the seat belt webbing out of the
retractor. Then, allow the webbing to re-
tract back into the retractor. As the web-bing retracts, you will hear a clicking
sound. This means the seat belt is now in
the Automatic Locking mode.
6. Try to pull the webbing out of the retractor.
If it is locked, you should not be able to
pull out any webbing. If the retractor is not
locked, repeat step 5.
7. Finally, pull up on any excess webbing to
tighten the lap portion around the child
restraint while you push the child restraint
rearward and downward into the vehicle
seat.
8. Test that the child restraint is installed
tightly by pulling back and forth on the
child seat at the belt path. It should not
move more than 25 mm in any direction.
Any seat belt system will loosen with time, so
check the belt occasionally, and pull it tight if
necessary.
Suitability of Passenger Seats for i-Size
Child Restraint System Use
The rear outboard seats of the vehicle are
type-approved to house the state-of-the-art
i-Size child restraint systems.
135

WARNING!
In a collision, people riding in these
areas are more likely to be seriously
injured or killed.
• Do not allow people to ride in any area of
your vehicle that is not equipped with
seats and seat belts.
• Be sure everyone in your vehicle is in a
seat and using a seat belt properly.
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They con-
tain carbon monoxide (CO), which is col-
orless and odorless. Breathing it can make
you unconscious and can eventually poi-
son you. To avoid breathing (CO), follow
these safety tips:
• Do not run the engine in a closed garage
or in confined areas any longer than
needed to move your vehicle in or out of
the area.
WARNING!
• If you are required to drive with the
trunk/liftgate/rear doors open, make sure
that all windows are closed and the cli-
mate control BLOWER switch is set at
high speed. DO NOT use the recircula-
tion mode.
• If it is necessary to sit in a parked vehicle
with the engine running, adjust your
heating or cooling controls to force out-
side air into the vehicle. Set the blower
at high speed.
The best protection against carbon monoxide
entry into the vehicle body is a properly main-
tained engine exhaust system.
Whenever a change is noticed in the sound of
the exhaust system, when exhaust fumes can
be detected inside the vehicle, or when the
underside or rear of the vehicle is damaged,
have a competent mechanic inspect the com-
plete exhaust system and adjacent body ar-
eas for broken, damaged, deteriorated, or
mispositioned parts. Open seams or loose
connections could permit exhaust fumes to
seep into the passenger compartment. Inaddition, inspect the exhaust system each
time the vehicle is raised for lubrication or oil
change. Replace as required.
Safety Checks You Should Make Inside
The Vehicle
Seat Belts
Inspect the seat belt system periodically,
checking for cuts, frays, and loose parts.
Damaged parts must be replaced immedi-
ately. Do not disassemble or modify the sys-
tem.
Front seat belt assemblies must be replaced
after a collision. Rear seat belt assemblies
must be replaced after a collision if they have
been damaged (i.e., bent retractor, torn web-
bing, etc.). If there is any question regarding
seat belt or retractor condition, replace the
seat belt.
Air Bag Warning Light
The Air Bag warning lightwill turn on for
four to eight seconds as a bulb check when
the ignition switch is first turned to ON/RUN.
If the light is either not on during starting,
137

stays on, or turns on while driving, have the
system inspected at an authorized dealer as
soon as possible. After the bulb check, this
light will illuminate with a single chime when
a fault with the Air Bag System has been
detected. It will stay on until the fault is
removed. If the light comes on intermittently
or remains on while driving, have an autho-
rized dealer service the vehicle immediately.
Refer to “Occupant Restraint Systems” in
“Safety” for further information.
Defroster
Check operation by selecting the defrost
mode and place the blower control on high
speed. You should be able to feel the air
directed against the windshield. See an au-
thorized dealer for service if your defroster is
inoperable.
Floor Mat Safety Information
Always use floor mats designed to fit your
vehicle. Only use a floor mat that does not
interfere with the operation of the accelera-
tor, brake or clutch pedals. Only use a floor
mat that is securely attached using the floormat fasteners so it cannot slip out of position
and interfere with the accelerator, brake or
clutch pedals or impair safe operation of your
vehicle in other ways.
WARNING!
An improperly attached, damaged, folded,
or stacked floor mat, or damaged floor mat
fasteners may cause your floor mat to
interfere with the accelerator, brake, or
clutch pedals and cause a loss of vehicle
control. To prevent SERIOUS INJURY or
DEATH:
• ALWAYS securely attach
your floor
mat using the floor mat fasteners. DO
NOT install your floor mat upside down
or turn your floor mat over. Lightly pull to
confirm mat is secured using the floor
mat fasteners on a regular basis.
• ALWAYS REMOVE THE EXISTING
FLOOR MAT FROM THE VEHICLE
before installing any other floor mat.
NEVER install or stack an additional
floor mat on top of an existing floor mat.
• ONLY install floor mats designed to fit
your vehicle. NEVER install a floor mat
WARNING!
that cannot be properly attached and
secured to your vehicle. If a floor mat
needs to be replaced, only use a FCA
approved floor mat for the specific
make, model, and year of your vehicle.
• ONLY use the driver’s side floor mat on
the driver’s side floor area. To check for
interference, with the vehicle properly
parked with the engine off, fully depress
the accelerator, the brake, and the
clutch pedal (if present) to check for
interference. If your floor mat interferes
with the operation of any pedal, or is not
secure to the floor, remove the floor mat
from the vehicle and place the floor mat
in your trunk.
• ONLY use the passenger’s side floor mat
on the passenger’s side floor area.
• ALWAYS make sure objects cannot fall
or slide into the driver’s side floor area
when the vehicle is moving. Objects can
become trapped under accelerator,
brake, or clutch pedals and could cause
a loss of vehicle control.

AutoPark
AutoPark is a supplemental feature to assist
in placing the vehicle in PARK should the
situations on the following pages occur. 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.
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 blink-
ing) “P” is indicated in the instrument
cluster display and on the gear selector.
If the "P" indicator is blinking, your ve-
hicle is not in PARK. As an added pre-
caution, 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.
If the vehicle is not in PARK and the driver turns
off the engine, the vehicle may AutoPark.
AutoPark will engage when all of these con-
ditions are met:
• Vehicle is equipped with an 8-speed trans-
mission
143

ALWAYS DO A VISUAL CHECKthat your vehicle
is in PARK by looking for the "P" in the
instrument cluster display and on the shifter.
As an added precaution, always apply the
parking brake when exiting the vehicle.
Normal Starting — Diesel Engine
1. The gear selector must be in the NEU-
TRAL or PARK position before you can
start the engine.
2. Place the ignition in the ON position.
3. Watch for the “Wait To Start Light” in the
instrument cluster. Refer to “Instrument
Cluster” in “Getting To Know Your Instru-
ment Panel” for further review. It will glow
for two to ten seconds or more, depending
on engine temperature. When the “Wait
To Start Light” goes out, the engine is
ready to start.
4. Tip Start Feature
Do notpress the accelerator. Cycle the
ignition to the START position and then
release it. The starter motor will continue
to run, and it will automatically disengage
when the engine is running. If the engine
fails to start, the starter will disengageautomatically in 25 seconds. If this oc-
curs, cycle the ignition to the LOCK posi-
tion, wait 25 to 30 seconds, then repeat
the “Normal Starting” procedure.
NOTE:
The starter motor may run up to 30 sec-
onds in very cold conditions until the
engine is started. The starter can be dis-
engaged by cycling the ignition to the
OFF position, if required.
5. After the engine starts, allow it to idle for
approximately 30 seconds before driving.
This allows oil to circulate and lubricate
the turbocharger.
Diesel Engine Warm-Up
Avoid full throttle operation when the engine
is cold. When starting a cold engine, bring the
engine up to operating speed slowly to allow
the oil pressure to stabilize as the engine
warms up.NOTE:
High-speed, no-load running of a cold engine
can result in excessive white smoke and poor
engine performance. No-load engine speeds
should be kept under 1,200 rpm during the
warm-up period, especially in cold, ambient
temperature conditions.
If temperatures are below 32°F (0°C), oper-
ate the engine at moderate speeds for five
minutes before full loads are applied.
Diesel Engine Idling — In Cold Weather
Avoid prolonged idling in ambient tempera-
tures below 0°F (-18°C). Long periods of
idling may be harmful to your engine because
combustion chamber temperatures can drop
so low that the fuel may not burn completely.
Incomplete combustion allows carbon and
varnish to form on piston rings and injector
nozzles. Also, the unburned fuel can enter
the crankcase, diluting the oil and causing
rapid wear to the engine.
