2020 JEEP PATRIOT check engine light

check. If the light remains on after the bulb
check, it indicates that there is a problem with
the electronics. In addition, if the light begins to
flash after the bulb check, it indicates that
someone used an invalid RKE Key Fob to start
the engine. Either of these conditions will result
in the engine being shut off after two seconds.
If the Vehicle Security Light turns on during
normal vehicle operation (vehicle running for
longer than 10 seconds), it indicates that there
is a fault in the electronics. Should this occur,
have the vehicle serviced as soon as possible
by an authorized dealer.
CAUTION!
The Sentry Key Immobilizer system is not
compatible with some aftermarket remote
starting systems. Use of these systems may
result in vehicle starting problems and loss of
security protection.
All of the RKE Key Fobs provided with your new
vehicle have been programmed to the vehicleelectronics. See your authorized dealer if you
require replacement or additional RKE Key
Fobs for your vehicle.
Replacement RKE Key Fobs
NOTE:
Only RKE Key Fobs that have been pro-
grammed to the vehicle electronics can be
used to start the vehicle. Once a Sentry Key
has been programmed to a vehicle, it cannot
be programmed to any other vehicle.
CAUTION!
Always remove the Sentry Keys from the
vehicle and lock all doors when leaving the
vehicle unattended.
Duplication of RKE Key Fobs consists of pro-
gramming a blank key to the vehicle electronics.
A blank RKE Key Fob is one which has never
been programmed. See your authorized dealer
if you require replacement or additional RKE
Key Fobs for your vehicle.NOTE:

VEHICLE SECURITY ALARM —
IF EQUIPPED
The Vehicle Security Alarm monitors the doors,
hood, liftgate, and ignition switch for unauthor-
ized operation.
If something triggers the Vehicle Security Alarm
the horn will sound for 29 seconds and turn off
all of the visual signals after an additional 31
seconds. If the triggering device is not deacti-
vated, the horn will sound again after a five
second delay for another 30 seconds. If the
trigger remains present, this cycle will repeat for
up to five minutes.

Enhanced Accident Response System
Reset Procedure
In order to reset the Enhanced Accident Re-
sponse System functions after an event, the
ignition must be changed from the START or
ON/RUN position to the OFF position. Carefully
check the vehicle for fuel leaks in the engine
compartment and on the ground near the en-
gine compartment and fuel tank before resetting
the system and starting the engine.
Air Bag Warning Light
The air bags must be ready to
inflate for your protection in a colli-
sion. The Occupant Restraint Con-
troller (ORC) monitors the internal
circuits and interconnecting wiring
associated with air bag system electrical com-
ponents.The ORC monitors the readiness of the elec-
tronic parts of the air bag system whenever the
ignition is placed in the START or ON/RUN
position. If the ignition is in the OFF position or
in the ACC position, the air bag system is not on
and the air bags will not inflate.
The ORC contains a backup power supply
system that may deploy the air bags even if the
battery loses power or it becomes disconnected
prior to deployment.
The ORC turns on the Air Bag Warning Light in
the instrument panel for approximately four to
eight seconds for a self-check when the ignition
is first placed in the ON/RUN position. After the
self-check, the Air Bag Warning Light will turn
off. If the ORC detects a malfunction in any part
of the system, it turns on the Air Bag Warning
Light, either momentarily or continuously. A
single chime will sound to alert you if the light
comes on again after initial startup.
The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag Warning
Light if a malfunction is detected that could
affect the air bag system. The diagnostics also
record the nature of the malfunction. While theair bag system is designed to be maintenance
free, if any of the following occurs, have an
authorized dealer service the air bag system
immediately.
•The Air Bag Warning Light does not come on
during the four to eight seconds when the
ignition is first placed in the ON/RUN posi-
tion.
•The Air Bag Warning Light remains on after
the four to eight-second interval.
•The Air Bag Warning Light comes on inter-
mittently or remains on while driving.
NOTE:
If the speedometer, tachometer, or any en-
gine related gauges are not working, the
Occupant Restraint Controller (ORC) may
also be disabled. In this condition the air
bags may not be ready to inflate for your
protection. Have an authorized dealer ser-
vice the air bag system immediately.

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.
