2021 JEEP PATRIOT engine coolant

WARNING!(Continued)
•Always make sure that objects cannot fall
into the driver footwell while the vehicle is
moving. Objects can become trapped un-
der the brake pedal and accelerator pedal
causing a loss of vehicle control.
•If required, mounting posts must be prop-
erly installed, if not equipped from the
factory.
Failure to properly follow floor mat installa-
tion or mounting can cause interference with
the brake pedal and accelerator pedal opera-
tion causing loss of control of the vehicle.
Periodic Safety Checks You Should
Make Outside The Vehicle
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones, nails,
glass, or other objects lodged in the tread or
sidewall. Inspect the tread for cuts and cracks.
Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the
tires (including spare) for proper cold inflation
pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight park-
ing for fuel, engine coolant, oil, or other fluid
leaks. Also, if gasoline fumes are detected or if
fuel, power steering fluid (if equipped), or brake
fluid leaks are suspected. The cause should be
located and corrected immediately.

1. Speedometer
•The Speedometer shows the vehicle
speed in miles per hour (MPH) and kilo-
meters per hour (km/h).
NOTE:
A chime will sound when the vehicle speed
is above 120 km/h.
Odometer Display / Trip Odometer Dis-
playThis display indicates the total dis-
tance the vehicle has been driven.
2. Tachometer
•This gauge measures engine revolutions
per minute (RPM x 1000). Before the
pointer reaches the red area, ease up on
the accelerator to prevent engine damage.
3. Temperature Gauge
•The temperature gauge shows engine
coolant temperature. Any reading within
the normal range indicates that the engine
cooling system is operating satisfactorily.
•The gauge pointer will likely indicate a
higher temperature when driving in hot
weather or up mountain grades. It shouldnot be allowed to exceed the upper limits
of the normal operating range.
CAUTION!
Driving with a hot engine cooling system
could damage your vehicle. If the tempera-
ture gauge reads “H” pull over and stop the
vehicle. Idle the vehicle with the air condi-
tioner turned off until the pointer drops back
into the normal range. If the pointer remains
on the “H”, turn the engine off immediately
and call an authorized dealer for service.
WARNING!
A hot engine cooling system is dangerous.
You or others could be badly burned by
steam or boiling coolant. You may want to
call an authorized dealer for service if your
vehicle overheats. If you decide to look un-
der the hood yourself, see “Maintaining Your
Vehicle”. Follow the warnings under the
Cooling System Pressure Cap paragraph.4. Electronic Vehicle Information Center (EVIC)

Oil Pressure Warning Light
Red Telltale Light What It Means
Oil Pressure Warning Light
This light indicates low engine oil pressure. If the light turns on while driving, stop the vehicle and shut off the engine as
soon as possible. A chime will sound when this light turns on.
Do not operate the vehicle until the cause is corrected. This light does not indicate how much oil is in the engine. The en-
gine oil level must be checked under the hood.
Engine Temperature Warning Light
Red Warning Light What It Means
Engine Temperature Warning Light
This light warns of an overheated engine condition. As engine coolant temperatures rise and the gauge approachesH, this
indicator will illuminate and a single chime will sound after reaching a set threshold. Further overheating will cause a con-
tinuous chime sound for 4 minutes, or until the engine is allowed to cool, whichever comes first.
If the light turns on while driving, safely pull over and stop the vehicle. If the A/C system is on, turn it off. Also, shift the
transmission into NEUTRAL and idle the vehicle. If the temperature reading does not return to normal, turn the engine off
immediately and call for service. Refer to “If Your Engine Overheats” in “What To Do In Emergencies” for further informa-
tion.
126

Summer Operation
The engine cooling system must be protected
with a high-quality antifreeze coolant to provide
proper corrosion protection and to protect
against engine overheating. A solution of 50%
OAT (Organic Additive Technology) coolant that
meets the requirements of FCA Material Stan-
dard MS.90032 and 50% water is recom-
mended. Refer to “Maintenance Procedures” in
“Maintaining Your Vehicle” for proper coolant
selection.
Winter Operation
Use of the air Recirculation Mode during winter
months is not recommended because it may
cause window fogging.
Vacation Storage
Anytime you store your vehicle, or keep it out of
service (i.e., vacation) for two weeks or more,
run the air conditioning system at idle for about
five minutes in the fresh air and high blower
settings. This will ensure adequate system lu-
brication to minimize the possibility of compres-
sor damage when the system is started again.Window Fogging
Interior fogging on the windshield can be quickly
removed by turning the mode selector to De-
frost. The Defrost/Floor mode can be used to
maintain a clear windshield and provide suffi-
cient heating. If side window fogging becomes a
problem, increase blower speed. Vehicle win-
dows tend to fog on the inside in mild but rainy
or humid weather.
NOTE:
Recirculate without A/C should not be used
for long periods as fogging may occur.
Side Window Demisters
A side window demister outlet is located at each
end of the instrument panel. These non-
adjustable outlets direct air toward the side
windows when the system is in the FLOOR,
MIX, or DEFROST mode. The air is directed at
the area of the windows through which you view
the outside mirrors.Outside Air Intake
Make sure the air intake, located directly in front
of the windshield, is free of obstructions such as
leaves. Leaves collected in the air intake may
reduce airflow, and if they enter the plenum,
they could plug the water drains. In winter
months, make sure the air intake is clear of ice,
slush, and snow.
A/C Air Filter — If Equipped
The A/C Filter prevents most dust and pollen
from entering the cabin. The filter acts on air
coming from outside the vehicle and recircu-
lated air within the passenger compartment.
Refer to “Maintenance Procedures” in “Main-
taining Your Vehicle” for A/C Air Filter service
information or see your authorized dealer for
service. Refer to “Maintenance Schedules” in
“Maintaining Your Vehicle” for filter service inter-
vals.

NOTE:
Even if the transmission can be reset, we
recommend that you visit your authorized
dealer at your earliest possible conve-
nience. Your authorized dealer has diagnos-
tic equipment to determine if the problem
could recur.
If the transmission cannot be reset, authorized
dealer service is required.
Overdrive Operation
The automatic transmission includes an elec-
tronically controlled Overdrive (sixth gear). The
transmission will automatically shift into Over-
drive if the following conditions are present:
•The gear selector is in the DRIVE position.
•The transmission fluid has reached an ad-
equate temperature.
•The engine coolant has reached an ad-
equate temperature.
•The vehicle speed is sufficiently high.
•The driver is not heavily pressing the
accelerator.Torque Converter Clutch
A feature designed to improve fuel economy
has been included in the automatic transmis-
sion on your vehicle. A clutch within the torque
converter engages automatically at calibrated
speeds. This may result in a slightly different
feeling or response during normal operation in
the upper gears. When the vehicle speed drops
or during some accelerations, the clutch auto-
matically disengages.
NOTE:
Engagement of the torque converter clutch
is inhibited at very cold temperatures. Be-
cause the engine speed is higher when the
torque converter clutch is not engaged, it
may seem as if the transmission is not
shifting into Overdrive when cold. This is
normal. The torque converter clutch will
function normally once the transmission is
sufficiently warm.
Continuously Variable Automatic
Transmission (CVT) — If Equipped
The transmission gear position display (located
in the instrument cluster) indicates the transmis-
sion gear range. You must press the brakepedal to move the gear selector out of PARK
(refer to “Brake/Transmission Shift Interlock
System” in this section). To drive, move the gear
selector from PARK or NEUTRAL to the DRIVE
position.
NOTE:
The Continuously Variable Automatic Trans-
mission (CVT) changes ratios in a continu-
ous manner. This may sometimesfeelas if
it is slipping, but this is normal and does not
harm anything.
Only shift from DRIVE to PARK or REVERSE
when the accelerator pedal is released and the
vehicle is stopped. Be sure to keep your foot on
the brake pedal when shifting between these
gears.
The transmission gear selector has only PARK,
REVERSE, NEUTRAL, and DRIVE shift posi-
tions. Manual shifts can be made using the
AutoStick shift control (refer to"AutoStick"in
this section). Moving the gear selector to the left
or right (-/+) while in the DRIVE position will
manually select from a set of predefined trans-
mission gear ratios, and will display the current
gear in the instrument cluster as 1, 2, 3, etc.

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.
