2020 JEEP PATRIOT engine

NOTE:
Do not remove foreign objects (e.g., screws
or nails) from the tire.
(C) Injecting Tire Service Kit Sealant Into
The Deflated Tire:
•Always start the engine before turning ON
the Tire Service Kit.
NOTE:
Manual transmission vehicles must have the
parking brake engaged and the gear selec-
tor in NEUTRAL.
•After pushing the Power Button (4), the seal-
ant (white fluid) will flow from the Sealant
Bottle (1) through the Sealant Hose (6) and
into the tire.
NOTE:
Sealant may leak out through the puncture
in the tire.
If the sealant (white fluid) does not flow
within0–10seconds through the Sealant
Hose (6):
1. Push the Power Button (4) to turn Off the Tire
Service Kit. Disconnect the Sealant Hose (6)from the valve stem. Make sure the valve
stem is free of debris. Reconnect the Seal-
ant Hose (6) to the valve stem. Check that
the Mode Select Knob (5) is in the Sealant
Mode position and not Air Mode. Push the
Power Button (4) to turn On the Tire Service
Kit.
2. Connect the Power Plug (8) to a different 12
Volt power outlet in your vehicle or another
vehicle, if available. Make sure the engine is
running before turning ON the Tire Service
Kit.
3. The Sealant Bottle (1) may be empty due to
previous use. Call for assistance.
NOTE:
If the Mode Select Knob (5) is on Air Mode
and the pump is operating, air will dispense
from the Air Pump Hose (7) only, not the
Sealant Hose (6).
If the sealant (white fluid) does flow through
the Sealant Hose (6):
1. Continue to operate the pump until sealant is
no longer flowing through hose (typicallytakes 30 - 70 seconds). As the sealant flows
through the Sealant Hose (6), the Pressure
Gauge (3) can read as high as 70 psi (4.8
Bar). The Pressure Gauge (3) will decrease
quickly from approximately 70 psi (4.8 Bar)
to the actual tire pressure when the Sealant
Bottle (1) is empty.
2. The pump will start to inject air into the tire
immediately after the Sealant Bottle (1) is
empty. Continue to operate the pump and
inflate the tire to the pressure indicated on
the tire pressure label on the driver-side
latch pillar (recommended pressure). Check
the tire pressure by looking at the Pressure
Gauge (3).
If the tire does not inflate to at least 26 psi
(1.8 Bar) pressure within 15 minutes:
•The tire is too badly damaged. Do not at-
tempt to drive the vehicle further. Call for
assistance.

JUMP-STARTING
PROCEDURES
If your vehicle has a discharged battery it can be
jump-started using a set of jumper cables and a
battery in another vehicle or by using a portable
battery booster pack. Jump-starting can be dan-
gerous if done improperly so please follow the
procedures in this section carefully.
NOTE:
When using a portable battery booster pack
follow the manufacturer’s operating instruc-
tions and precautions.
CAUTION!
Do not use a portable battery booster pack or
any other booster source with a system
voltage greater than 12 Volts or damage to
the battery, starter motor, alternator or elec-
trical system may occur.
WARNING!
Do not attempt jump-starting if the battery is
frozen. It could rupture or explode and cause
personal injury.
Preparations For Jump-StartThe battery in your vehicle is located in the front
of the engine compartment below the air intake
duct. To access the battery remove the air
intake duct by turning the two finger screws,
located on the radiator support.
WARNING!
•Take care to avoid the radiator cooling fan
whenever the hood is raised. It can start
anytime the ignition switch is ON. You can
be injured by moving fan blades.
•Remove any metal jewelry such as rings,
watch bands and bracelets that could
make an inadvertent electrical contact.
You could be seriously injured.

WARNING!(Continued)
•Batteries contain sulfuric acid that can
burn your skin or eyes and generate hy-
drogen gas which is flammable and explo-
sive. Keep open flames or sparks away
from the battery.
1. Set the parking brake, shift the automatic
transmission into PARK (manual transmis-
sion to NEUTRAL) and turn the ignition to
LOCK.
2. Turn off the heater, radio, and all unneces-
sary electrical accessories.
3. If using another vehicle to jump-start the
battery, park the vehicle within the jumper
cables reach, set the parking brake and
make sure the ignition is OFF.
WARNING!
Do not allow vehicles to touch each other as
this could establish a ground connection and
personal injury could result.
Jump-Starting Procedure
WARNING!
Failure to follow this jump-starting procedure
could result in personal injury or property
damage due to battery explosion.
CAUTION!
Failure to follow these procedures could re-
sult in damage to the charging system of the
booster vehicle or the discharged vehicle.
NOTE:
Remove Air Intake before proceeding with
this Jump-Starting procedure.Connecting The Jumper Cables
1. Connect the positive(+)end of the jumper
cable to the positive(+)post of the dis-
charged vehicle.
2. Connect the opposite end of the positive(+)
jumper cable to the positive(+)post of the
booster battery.
3. Connect the negative end(-)of the jumper
cable to the negative(-)post of the booster
battery.
4. Connect the opposite end of the negative(-)
jumper cable to a good engine ground (ex-
posed metal part of the discharged vehicle’s
engine) away from the battery and the fuel
injection system.
WARNING!
Do not connect the jumper cable to the
negative(-)post of the discharged battery.
The resulting electrical spark could cause

WARNING!(Continued)
the battery to explode and could result in
personal injury. Only use the specific ground
point, do not use any other exposed metal
parts.
5. Start the engine in the vehicle that has the
booster battery, let the engine idle a few
minutes, and then start the engine in the
vehicle with the discharged battery.
6. Once the engine is started, remove the
jumper cables in the reverse sequence:
Disconnecting The Jumper Cables
1. Disconnect the negative(-)end of the
jumper cable from the engine ground of the
vehicle with the discharged battery.
2. Disconnect the opposite end of the negative
(-)jumper cable from the negative(-)post of
the booster battery.3. Disconnect the positive(+)end of the jumper
cable from the positive(+)post of the
booster battery.
4. Disconnect the opposite end of the positive
(+)jumper cable from the positive(+)post of
the vehicle with the discharged battery.
5. Reinstall the air intake duct.
If frequent jump-starting is required to start your
vehicle you should have the battery and charg-
ing system inspected at your authorized dealer.
CAUTION!
Accessories plugged into the vehicle power
outlets draw power from the vehicle’s bat-
tery, even when not in use (i.e., cellular
devices, etc.). Eventually, if plugged in long
enough without engine operation, the vehi-
cle’s battery will discharge sufficiently to de-
grade battery life and/or prevent the engine
from starting.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or
snow, it can often be moved using a rocking
motion. Turn the steering wheel right and left to
clear the area around the front wheels. Then
shift back and forth between DRIVE and RE-
VERSE (with automatic transmission) or 2nd
gear and REVERSE (with manual transmis-
sion), while gently pressing the accelerator. Use
the least amount of accelerator pedal pressure
that will maintain the rocking motion, without
spinning the wheels, or racing the engine.
CAUTION!
Racing the engine or spinning the wheels
may lead to transmission overheating and
failure. Allow the engine to idle with the
transmission in NEUTRAL for at least one
minute after every five rocking-motion
cycles. This will minimize overheating and
reduce the risk of clutch or transmission
failure during prolonged efforts to free a
stuck vehicle.
243

NOTE:
Push theESC Offswitch, to place the
Electronic Stability Control (ESC) system in
Partial Offmode, before rocking the ve-
hicle. Refer to “Electronic Brake Control” in
“Starting And Operating” for further infor-
mation. Once the vehicle has been freed,
push theESC Offswitch again to restore
ESC Onmode.
CAUTION!
•
When “rocking” a stuck vehicle by shifting
between DRIVE/2nd gear and REVERSE,
do not spin the wheels faster than 15 mph
(24 km/h), or drivetrain damage may result.
•Revving the engine or spinning the wheels
too fast may lead to transmission over-
heating and failure. It can also damage the
tires. Do not spin the wheels above
30 mph (48 km/h) while in gear (no trans-
mission shifting occurring).
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
speeds may cause damage, or even failure,
of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle’s
wheels faster than 30 mph (48 km/h) or for
longer than 30 seconds continuously without
stopping when you are stuck and do not let
anyone near a spinning wheel, no matter
what the speed.
GEAR SELECTOR OVERRIDE
If a malfunction occurs and the gear selector
cannot be moved out of the PARK position, you
can use the following procedure to temporarily
move the gear selector:
1. Turn the engine OFF.
2. Firmly apply the parking brake.3. Using a small screwdriver or similar tool,
remove the gear selector override access
cover (located on the right side of the gear
selector housing).
4. Turn the ignition switch to the ACC or ON/
RUN position, but do not start the engine.
5. Press and maintain firm pressure on the
brake pedal.
6. Insert the screwdriver or similar tool into the
access port, and push and hold the override
release lever forward.Gear Selector Override Access Cover
