2019 JEEP PATRIOT ignition

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 TPMS Message
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 SYSTEM” mes-
sage for a minimum of five seconds. This text
message is then followed by a graphic display,
with “- -“ in place of the pressure value(s)
indicating which Tire Pressure Monitoring Sen-
sor(s) is not being received.If the ignition key is cycled, this sequence will
repeat, providing the system fault still exists. If
the system fault no longer exists, the Tire Pres-
sure Monitoring Telltale Light will no longer
flash, the"SERVICE TPM SYSTEM"text mes-
sage will not be present, and a pressure value
will be displayed instead of dashes. A system
fault can occur with any of the following sce-
narios:
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. 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.
The EVIC will also display a"SERVICE TPM
SYSTEM"message for a minimum of five sec-
onds when a system fault related to an incorrect
sensor location fault is detected. In this case,
the"SERVICE TPM SYSTEM"message is then
followed with a graphic display with pressure
values still shown. This indicates that the pres-
sure values are still being received from the
TPM sensors but they may not be located in the
correct vehicle position. The system still needs
to be serviced as long as the"SERVICE TPM
SYSTEM"message is displayed.
NOTE:
Your vehicle is equipped with a compact
spare wheel and tire assembly.
Tire Pressure Monitoring Display
208

1. The compact spare tire does not have a tire
pressure monitoring sensor. Therefore, the
TPMS will not monitor the tire pressure in the
compact spare tire.
2. If you install the compact 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
still turn ON due to the low tire. The “LOW
TIRE” text message and the graphic with the
low tire pressure flashing will be displayed.
3. However, 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” message for a
minimum of five seconds and then display
dashes (- -) in place of the pressure values.
4. For each subsequent ignition key cycle, a
chime will sound and the Tire Pressure
Monitoring Telltale Light will flash on and offfor 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 values.
5.
Once you repair or replace the original road
tire and reinstall it on the vehicle in place of the
compact spare tire, the TPMS will update
automatically and the Tire Pressure Monitoring
Telltale 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 10
minutes above 15 mph (24 km/h) in order for
the TPMS to receive this information.
TPMS Deactivation — If EquippedThe TPMS can be deactivated if replacing all
four wheel and tire assemblies (road tires) with
wheel and tire assemblies that do not have
TPMS Sensors, such as when installing Winter
wheel and tire assemblies on your vehicle. To
deactivate the TPMS, first, replace all four
wheel and tire assemblies (road tires) with tires
not equipped with Tire Pressure Monitoring(TPM) Sensors. Then, drive the vehicle for 10
minutes above 15 mph (24 km/h). The TPMS
will chime, the “TPM Telltale Light” will flash on
and off for 75 seconds and then remain on and
the Electronic Vehicle Information Center
(EVIC) will display the “SERVICE TPM SYS-
TEM” message and then display dashes (--) in
place of the pressure values. Beginning with the
next ignition switch cycle, the TPMS will no
longer chime or flash the TPM telltale and
display the “SERVICE TPM SYSTEM” message
in the EVIC 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 TPM sensors. Then, drive the
vehicle for up to 10 minutes above 15 mph
(24 km/h). The TPMS will chime, the “TPM
Telltale Light” will flash on and off for 75 sec-
onds and then turn off, and the Electronic
Vehicle Information Center (EVIC) will display
the “SERVICE TPM SYSTEM” message. The
EVIC will also display pressure values in place
of the dashes. On the next ignition switch cycle
209

the “SERVICE TPM SYSTEM” message will no
longer be displayed as long as no system fault
exists.
To reactivate the TPMS, replace all four wheel
and tire assemblies (road tires) with tires
equipped with TPM sensors. Then, drive the
vehicle for up to 10 minutes above 15 mph
(24 km/h). The TPMS will chime, the “TPM
Telltale Light” will flash on and off for 75 sec-
onds and then turn off, and the Electronic
Vehicle Information Center (EVIC) will display
the “SERVICE TPM SYSTEM” message. The
EVIC will also display pressure values in place
of the dashes. On the next ignition switch cycle,
the “SERVICE TPM SYSTEM” message will no
longer be displayed as long as no system fault
exists.
FUEL REQUIREMENTS —
GASOLINE ENGINE
All gasoline engines are designed to meet all
emissions regulations and provide excellent
fuel economy and performance when using
high quality unleaded gasoline with a minimum
research octane rating (RON) of 91.Light spark knock at low engine speeds is not
harmful to your engine. However, continued
heavy spark knock at high speeds can cause
damage and immediate service is required.
Poor quality gasoline can cause problems such
as hard starting, stalling, and hesitations. If you
experience these symptoms, try another brand
of gasoline before considering service for the
vehicle.
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 may help improve fuel economy, re-
duce emissions, and maintain vehicle perfor-
mance.
Poor quality gasoline can cause problems such
as hard starting, stalling and stumble. If you
experience these problems, try another brand
of gasoline before considering service for the
vehicle.
Methanol(Methyl) is used in a variety of concentrations
when blended with unleaded gasoline. You mayfind fuels containing 3% or more methanol
along with other alcohols called cosolvents.
Problems that result from using methanol/
gasoline blends are not the responsibility of the
manufacturer.
CAUTION!
Do not use gasolines containing Methanol.
Use of these blends may result in starting
and drivability problems and may damage
critical fuel system components.
EthanolThe manufacturer recommends that your ve-
hicle be operated on fuel containing no more
than 15% ethanol. Purchasing your fuel from a
reputable supplier may reduce the risk of ex-
ceeding this 15% limit and/or of receiving fuel
with abnormal properties. It should also be
noted that an increase in fuel consumption
should be expected when using ethanol-
blended fuels, due to the lower energy content
of ethanol. Problems that result from using

WARNING!(Continued)
•Guard against carbon monoxide with
proper maintenance. Have the exhaust
system inspected every time the vehicle is
raised. Have any abnormal conditions re-
paired promptly. Until repaired, drive with
all side windows fully open.
•Keep the liftgate closed when driving your
vehicle to prevent carbon monoxide and
other poisonous exhaust gases from en-
tering the vehicle.
ADDING FUEL
Locking Fuel Filler Cap (Gas Cap)The locking gas cap is inside the fuel filler door,
on the left side of the vehicle. If the gas cap is
lost or damaged, be sure the replacement cap
is for use with this vehicle.
1. Turn off the engine.2. Insert the ignition key into the fuel cap and
turn the key one-quarter turn to the right,
then rotate the fuel cap to the left to remove.
3. After removing the gas cap, place the gas
cap tether cable over a hook on the inside of
the fuel door. This keeps the gas cap sus-
pended away from and protects the vehicle’s
surface.
4. Rotate the ignition key back to the left to
remove the key from the cap.
5. To replace the cap, insert it into the filler neck
and tighten to the right until at least one click
is heard.NOTE:
•When the fuel nozzle “clicks” or shuts off,
the fuel tank is full.
•Tighten the gas cap about 1/4 turn until
you hear one click. This is an indication
that cap is properly tightened.
•If the gas cap is not tightened properly,
the MIL will come on. Be sure the gas cap
is tightened every time the vehicle is
refueled.
Loose Fuel Filler Cap MessageIf the vehicle diagnostic system determines that
the fuel filler cap is loose or improperly installed,
a “gASCAP” message will be displayed in the
Odometer/Trip Odometer in the instrument clus-
ter. Refer to “Warning And Indicator Lights” in
“Understanding Your Instrument Panel” for fur-
ther information. Tighten the fuel filler cap prop-
erly and push the odometer/trip odometer RE-
SET button to turn the message off. If the
problem continues, the message will appear the
next time the vehicle is started. Refer to “On-
board Diagnostic System” in “Maintaining Your
Vehicle” for further information.

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located
on the instrument panel below the climate
controls.
Push the switch to turn on the Hazard
Warning flasher. When the switch is
activated, all directional turn signals
will flash on and off to warn oncoming traffic of
an emergency. Push the switch a second time
to turn off the Hazard Warning flashers.
This is an emergency warning system and it
should not be used when the vehicle is in
motion. Use it when your vehicle is disabled and
it is creating a safety hazard for other motorists.
When you must leave the vehicle to seek assis-
tance, the Hazard Warning flashers will con-
tinue to operate even though the ignition is
placed in the OFF position.
NOTE:
With extended use the Hazard Warning
flashers may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
•On the highways — slow down.
•In city traffic — while stopped, place the
transmission in NEUTRAL, but do not in-
crease engine idle speed.
NOTE:
There are steps that you can take to slow
down an impending overheat condition:
•If your air conditioner (A/C) is on, turn it
off. The A/C system adds heat to the
engine cooling system and turning the
A/C off can help remove this heat.
•You can also turn the temperature control
to maximum heat, the mode control to
floor and the blower control to high. This
allows the heater core to act as a supple-
ment to the radiator and aids in removing
heat from the engine cooling system.CAUTION!
Driving with a hot cooling system could dam-
age your vehicle. If the pointer rises to the
H(red) mark, the instrument cluster will
sound a chime. When safe, pull over and
stop the vehicle with the engine at idle. Turn
off the air conditioning and wait until the
pointer drops back into the normal range. If
the pointer remains on theH(red) mark for
more than a minute, turn the engine off
immediately and call for service.
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam com-
ing from under the hood, do not open the
hood until the radiator has had time to cool.
Never try to open a cooling system pressure
cap when the radiator or coolant bottle is hot.
