JEEP WRANGLER 2016 JK / 3.G Owners Manual

If you install the spare tire in place of a road tire that
has a pressure below the low-pressure warning limit,
upon the next ignition key cycle, a chime will sound
and the “Tire Pressure Monitoring Telltale Light” will
turn ON. After driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), the “Tire Pressure Monitor-
ing Telltale Light” will flash on and off for 75 seconds
and then remain on solid. For each subsequent ignition
key cycle, a chime will sound and the “Tire Pressure
Monitoring Telltale Light” will flash on and off for 75
seconds and then remain on solid. Once you repair or
replace the original road tire, and reinstall it on the
vehicle in place of the spare tire, the TPMS will update
automatically and the “Tire Pressure Monitoring Tell-
tale Light” will turn OFF, as long as no tire pressure is
below the low-pressure warning limit in any of the
four active road tires. The vehicle may need to be
driven for up to 20 minutes above 15 mph (24 km/h)
in order for the TPMS to receive this information.Premium System — If Equipped
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim-mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the Receiver Module.

STARTING AND OPERATING 529

NOTE:It is particularly important, for you to regularly
check the tire pressure in all of your tires and to maintain
the proper pressure.
The Tire Pressure Monitor System (TPMS) consists of the
following components:
• Receiver Module
• Four Tire Pressure Monitoring Sensors
• Various Tire Pressure Monitoring System Messages,
which display in the Electronic Vehicle Information
Center (EVIC), and a graphic displaying tire pressures
• Tire Pressure Monitoring Telltale Light
A tire pressure monitoring sensor is located in the spare
wheel, if the vehicle is equipped with a matching full-size
spare wheel and tire assembly. The matching full-size
spare tire can be used in place of any of the four road
tires.Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster, and an au-
dible chime will be activated, when one or more of the
four active road tire pressures are low. In addition, the
EVIC will display a “LOW TIRE” message for a mini-
mum of five seconds. An “Inflate to XX” message and a
graphic display of the pressure value(s) with the low
tire(s) “flashing” will also be displayed. Refer to “Elec-
tronic Vehicle Information Center (EVIC)” in “Under-
standing Your Instrument Panel” for further information.
NOTE: Your system can be set to display pressure units
in PSI, kPa, or BAR.
530 STARTING AND OPERATING

Should a low tire condition occur on any of the four
active road tire(s), you should stop as soon as possible,
and inflate the low tire(s) that is “flashing” on the graphic
display to the vehicle’s recommended cold tire pressure
inflation value shown in the “Inflate to XX” message. The
system will automatically update, the graphic display ofthe pressure value(s) will stop “flashing,” and the Tire
Pressure Monitoring Telltale Light will extinguish once
the updated tire pressure(s) have been received.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi (30 kPa)
above the recommended cold placard pressure in order
to turn the Tire Pressure Monitoring Telltale Light off.
The vehicle may need to be driven for up to 10 minutes
above 15 mph (24 km/h) to receive this information.
SERVICE TPM SYSTEM Warning
The “Tire Pressure Monitoring Telltale Light” will flash
on and off for 75 seconds, and remain on solid when a
system fault is detected. The system fault will also sound
a chime. The EVIC will display a “SERVICE TPM SYS-
TEM” message for a minimum of five seconds. This
message is then followed by a graphic display, with “- -“Tire Pressure Monitor Display
5
STARTING AND OPERATING 531

in place of the pressure value(s), indicating which Tire
Pressure Monitoring Sensor(s) is not being received.
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the “Tire Pressure Monitoring Telltale
Light” will no longer flash, theSERVICE TPM SYSTEM
message will not be present, and a pressure value will be
displayed instead of dashes. A system fault can occur by
any of the following:
1. Jamming due to electronic devices or driving next to facilities emitting the same Radio Frequencies as the
TPM sensors.
2. Installing some form of aftermarket window tinting that affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle. 5. Using wheels/tires not equipped with TPM sensors.
NOTE:
•
If your vehicle is equipped with a matching full-size
spare wheel and tire assembly, it has a tire pressure
monitoring sensor, and can be monitored by the Tire
Pressure Monitoring System (TPMS) when swapped
with a low pressure road tire.. In the event that the
matching full-size spare tire is swapped with a low
pressure road tire, the next ignition switch cycle will
still show the “Tire Pressure Monitoring Telltale Light”
to be ON, a chime to sound, a “LOW TIRE” message to
appear in the EVIC, and the graphic display will still
show the Inflate to XX message and the low tire
pressure value “flashing.” Driving the vehicle for up to
10 minutes above 15 mph (24 km/h) will turn OFF the
“Tire Pressure Monitoring Telltale Light” as long as
none of road tires are below the low pressure warning
threshold.
532 STARTING AND OPERATING

•If your vehicle is not equipped with a matching
full-size spare wheel and tire assembly, it does not
have a tire pressure monitoring sensor in the spare tire.
The TPMS will not be able to monitor the tire pressure.
If you install the spare tire in place of a road tire that
has a pressure below the low-pressure warning limit,
upon the next ignition switch cycle, the “Tire Pressure
Monitoring Telltale Light” will remain ON, a chime
will sound, and the EVIC will still display the Inflate
to XX message and a “flashing” pressure value in the
graphic display. After driving the vehicle for up to 10
minutes above 15 mph (24 km/h), the “Tire Pressure
Monitoring Telltale Light” will flash on and off for 75
seconds and then remain on solid. In addition, the
EVIC will display a “SERVICE TPM SYSTEM mes-
sage for a minimum of five seconds and then display
dashes (- -) in place of the pressure value. For each
subsequent ignition switch cycle, a chime will sound,
the “Tire Pressure Monitoring Telltale Light” will flash on and off for 75 seconds and then remain on solid,
and the EVIC will display a
SERVICE TPM SYSTEM
message for a minimum of five seconds and then
display dashes (- -) in place of the pressure value.
• Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the spare tire, the
TPMS will update automatically.
In addition, the “Tire Pressure Monitoring Telltale Light”
will turn OFF and the graphic in the EVIC will display a
new pressure value instead of dashes (- -), as long as no
tire pressure is below the low-pressure warning limit in
any of the four active road tires. The vehicle may need to
be driven for up to 10 minutes above 15 mph (24 km/h)
in order for the TPMS to receive this information.

FUEL REQUIREMENTS
3.6L Engine
This engine is designed to meet all emis-
sions regulations and provide optimum
fuel economy and performance when us-
ing high quality unleaded “Regular” gaso-
line having a posted octane number of 87
as specified by the (R+M)/2 method. The use of higher
octane “Premium” gasoline is not required, as it will not
provide any benefit over “Regular” gasoline in these
engines.
While operating on gasoline with an octane number of
87, hearing a light knocking sound from the engine is not
a cause for concern. However, if the engine is heard
making a heavy knocking sound, see your dealer imme-
diately. Use of gasoline with an octane number lower
534 STARTING AND OPERATING

than 87 can cause engine failure and may void or not be
covered by the New Vehicle Limited Warranty.
Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience these
symptoms, try another brand of gasoline before consid-
ering service for the vehicle.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gasoline”.
Reformulated gasoline contains oxygenates and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.
The use of reformulated gasoline is recommended. Prop-
erly blended reformulated gasoline will provide im-
proved performance and durability of engine and fuel
system components.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as ethanol.
CAUTION!
DO NOT use gasoline containing methanol or gaso-
line containing more than 15% ethanol (E-15). Use of
these blends may result in starting and drivability
problems, damage critical fuel system components,
cause emissions to exceed the applicable standard,
and/or cause the “Malfunction Indicator Light” to
illuminate. Please observe pump labels as they
should clearly communicate if a fuel contains greater
than 15% ethanol (E-15).
5
STARTING AND OPERATING 535

Problems that result from using gasoline containing more
than 15% ethanol (E-15) or gasoline containing methanol
are not the responsibility of the manufacturer and may
void or not be covered under New Vehicle Limited
Warranty.
E-85 Usage In Non-Flex Fuel Vehicles
Non-Flex Fuel Vehicles (FFV) are compatible with gaso-
line containing up to 15% ethanol (E-15). Gasoline with
higher ethanol content may void the New Vehicle Lim-
ited Warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms:
•Operate in a lean mode.
• OBD II “Malfunction Indicator Light” on.
• Poor engine performance. •
Poor cold start and cold drivability.
• Increased risk for fuel system component corrosion.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl (MMT)
is a manganese-containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emissions system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content
of gasoline may not be indicated on the gasoline pump,
therefore, you should ask your gasoline retailer whether
the gasoline contains MMT. MMT is prohibited in Federal
and California reformulated gasoline.
536 STARTING AND OPERATING

Materials Added To Fuel
Besides using unleaded gasoline with the proper octane
rating, gasolines that contain detergents, corrosion and
stability additives are recommended. Using gasolines
that have these additives will help improve fuel
economy, reduce emissions, and maintain vehicle perfor-
mance. Designated TOP TIER Detergent Gasoline con-
tains a higher level of detergents to further aide in
minimizing engine and fuel system deposits. When avail-
able the usage of Top Tier Detergent gasoline is recom-
mended. Visit www.toptiergas.com for a list of TOP TIER
Detergent Gasoline Retailers.
Indiscriminate use of fuel system cleaning agents should
be avoided. Many of these materials intended for gum
and varnish removal may contain active solvents or
similar ingredients. These can harm fuel system gasket
and diaphragm materials.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•
The use of leaded gasoline is prohibited by Federal
law. Using leaded gasoline can impair engine perfor-
mance and damage the emissions control system.
• An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune
or malfunctioning and may require immediate ser-
vice. Contact your authorized dealer for service
assistance.

STARTING AND OPERATING 537

CAUTION!(Continued)
•The use of fuel additives, which are now being
sold as octane enhancers, is not recommended.
Most of these products contain high concentrations
of methanol. Fuel system damage or vehicle perfor-
mance problems resulting from the use of such
fuels or additives is not the responsibility of the
manufacturer and may void or not be covered
under the New Vehicle Limited Warranty.
NOTE: Intentional tampering with the emissions control
system can result in civil penalties being assessed against
you.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
• Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as
a garage, and never sit in a parked vehicle with the
engine running for an extended period. If the
vehicle is stopped in an open area with the engine
running for more than a short period, adjust the
ventilation system to force fresh, outside air into
the vehicle.
• Guard against carbon monoxide with proper main-
tenance. Have the exhaust system inspected every
