engine overheat JEEP PATRIOT 2019 Owner handbook (in English)

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.

WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite
and burn you. Care must be exercised when
filling or working around the washer solution.
Exhaust SystemThe best protection against carbon monoxide
entry into the vehicle body is a properly main-
tained engine exhaust system.
If you notice a change in the sound of the
exhaust system; or if the exhaust fumes can be
detected inside the vehicle; or when the under-
side or rear of the vehicle is damaged; have an
authorized technician inspect the complete ex-
haust system and adjacent body areas for bro-
ken, damaged, deteriorated, or mispositioned
parts. Open seams or loose connections could
permit exhaust fumes to seep into the passen-
ger compartment. In addition, have the exhaust
system inspected each time the vehicle is
raised for lubrication or oil change. Replace as
required.
WARNING!
•Exhaust gases can injure or kill. They
contain carbon monoxide (CO), which is
colorless and odorless. Breathing it can
make you unconscious and can eventually
poison you. To avoid breathing CO, refer to
“Safety Tips/Exhaust Gas” in “Things To
Know Before Starting Your Vehicle” for
further information.
•A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials might be grass or leaves coming
into contact with your exhaust system. Do
not park or operate your vehicle in areas
where your exhaust system can contact
anything that can burn.CAUTION!
•The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will
destroy the effectiveness of the catalyst as
an emissions control device and may seri-
ously reduce engine performance and
cause serious damage to the engine.
•Damage to the catalytic converter can
result if your vehicle is not kept in proper
operating condition. In the event of engine
malfunction, particularly involving engine
misfire or other apparent loss of perfor-
mance, have your vehicle serviced
promptly. Continued operation of your ve-
hicle with a severe malfunction could
cause the converter to overheat, resulting
in possible damage to the converter and
vehicle.
Under normal operating conditions, the catalytic
converter will not require maintenance. How-
ever, it is important to keep the engine properly
tuned to assure proper catalyst operation and
prevent possible catalyst damage.

The cap should be inspected and cleaned if
there is any accumulation of foreign material on
the sealing surfaces.
WARNING!
•The warning words “DO NOT OPEN HOT”
on the cooling system pressure cap are a
safety precaution. Never add engine cool-
ant (antifreeze) when the engine is over-
heated. Do not loosen or remove the cap
to cool an overheated engine. Heat causes
pressure to build up in the cooling system.
To prevent scalding or injury, do not re-
move the pressure cap while the system is
hot or under pressure.
•Do not use a pressure cap other than the
one specified for your vehicle. Personal
injury or engine damage may result.
Disposal Of Used Engine Coolant
Used ethylene glycol-based engine coolant (an-
tifreeze) is a regulated substance requiring
proper disposal. Check with your local authori-
ties to determine the disposal rules for yourcommunity. To prevent ingestion by animals or
children, do not store ethylene glycol-based
engine coolant (antifreeze) in open containers
or allow it to remain in puddles on the ground. If
ingested by a child or pet, seek emergency
assistance immediately. Clean up any ground
spills immediately.
Coolant Level
The coolant bottle provides a quick visual
method for determining that the coolant level is
adequate. With the engine idling and warm to
normal operating temperature, the level of the
engine coolant (antifreeze) in the bottle should
be between the “ADD” and “FULL” lines shown
on the bottle.
The radiator normally remains completely full,
so there is no need to remove the radiator cap
unless checking for the coolant freeze point or
replacing the engine coolant (antifreeze). Ad-
vise your service attendant of this. As long as
the engine operating temperature is satisfac-
tory, the coolant bottle need only be checked
once a month.When additional engine coolant (antifreeze) is
needed to maintain the proper level, it should be
added to the coolant bottle. Do not overfill.
Points To Remember
NOTE:
When the vehicle is stopped after a few
miles/kilometers of operation, you may ob-
serve vapor coming from the front of the
engine compartment. This is normally a re-
sult of moisture from rain, snow, or high
humidity accumulating on the radiator and
being vaporized when the thermostat opens,
allowing hot engine coolant (antifreeze) to
enter the radiator.
If an examination of your engine compartment
shows no evidence of radiator or hose leaks,
the vehicle may be safely driven. The vapor will
soon dissipate.
•Do not overfill the coolant expansion bottle.
•Check the coolant freeze point in the radiator
and in the coolant expansion bottle. If engine
coolant (antifreeze) needs to be added, the
contents of the coolant expansion bottle must
also be protected against freezing.
