2021 JEEP PATRIOT ABS

To Arm The System
1. Remove the RKE Key Fob from the ignition
and get out of the vehicle.
2. Lock the door using either the power door
lock
switch or the RKE Key Fob lockbutton and close all doors.
3. The Vehicle Security Light in the instrument
cluster will flash rapidly for approximately 16
seconds. This shows that the Vehicle Secu-
rity Alarm is arming. During this period, if a
door is opened, the ignition is placed in the
ON/RUN position, or the power door locks
are unlocked in any manner, the Vehicle
Security Alarm will automatically disarm. Af-
ter approximately 16 seconds, the Vehicle
Security Light will flash slowly. This shows
that the Vehicle Security Alarm is fully
armed.
Rearming Of The SystemIf something triggers the alarm, and no action is
taken to disarm it, the Vehicle Security Alarm
will turn off the horn after 29 seconds, turn off all
of the visual signals after one minute, and then
the Vehicle Security Alarm will rearm itself.
To Disarm The SystemPush UNLOCK on the RKE Key Fob, or insert
the key into the ignition and place the ignition in
the ON/RUN position.
If something has triggered the Vehicle Security
Alarm in your absence, the exterior lights blink
three times when you unlock the doors. Check
the vehicle for tampering. The Vehicle Security
Alarm is designed to protect your vehicle; how-
ever, you can create conditions where the Ve-
hicle Security Alarm will arm unexpectedly. If
you remain in the vehicle and lock the doors
with the RKE Key Fob, once the Vehicle Secu-
rity Alarm is armed (after 16 seconds), when
you pull the door handle to exit, the alarm will
sound. If this occurs, push the UNLOCK button
on the RKE Key Fob to disarm the Vehicle
Security Alarm.
Vehicle Security Alarm Manual
Override
The Vehicle Security Alarm will not arm if you
lock the doors using the manual door lock
plunger.
PREMIUM VEHICLE SECURITY
ALARM — IF EQUIPPED
The Premium Vehicle Security Alarm system
monitors the doors, hood latch, liftgate, and
ignition switch for unauthorized operation.
If something triggers the security alarm, the
audible alert will sound for 29 seconds and flash
the lights for 60 seconds. If the triggering device
is not deactivated, the audible alert will sound
again after a five-second delay for another 29
seconds. If the trigger remains present, this
cycle will repeat for up to five minutes.
If the intrusion sensor is enabled, the security
alarm system will also monitor the vehicle for
movement. When this portion of the alarm is
set, movement inside the vehicle or movement
of the vehicle will trigger the Vehicle Security
Alarm.

Bags fully inflate in less time than it takes to
blink your eyes. The air bags then quickly
deflate while helping to restrain the driver and
front passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the
knees of the driver and front passenger, and
position the front occupants for improved inter-
action with the Advanced Front Air Bags.
WARNING!
•Do not drill, cut, or tamper with the knee
impact bolsters in any way
•Do not mount any accessories to the knee
impact bolsters such as alarm lights, ste-
reos, citizen band radios, etc.
Supplemental Side Air Bags
Your vehicle is equipped with two types of side
air bags:
1.Supplemental Seat-Mounted Side Air
Bags (SABs): Located in the outboard
side of the front seats. The SABs aremarked with a “SRS AIRBAG” or “AIR-
BAG” label sewn into the outboard side
of the seats.
The SABs may help to reduce the risk of
occupant injury during certain side impacts
and/or vehicle rollover events, in addition to the
injury reduction potential provided by the seat
belts and body structure.When the SAB deploys, it opens the seam on
the outboard side of the seatback’s trim cover.
The inflating SAB deploys through the seat
seam into the space between the occupant and
the door. The SAB moves at a very high speed
and with such a high force that it could injure
occupants if they are not seated properly, or if
items are positioned in the area where the SAB
inflates. Children are at an even greater risk of
injury from a deploying air bag.WARNING!
Do not use accessory seat covers or place
objects between you and the Side Air Bags;
the performance could be adversely affected
and/or objects could be pushed into you,
causing serious injury.
2.Supplemental Side Air Bag Inflatable Cur-
tains (SABICs): Located above the side
windows. The trim covering the SABICs
is labeled “SRS AIRBAG” or “AIRBAG.”
Supplemental Seat-Mounted Side Air Bag
Label

SABICs may help reduce the risk of head or
other injuries to front and rear seat outboard
occupants in certain side impacts and/or vehicle
rollover events, in addition to the injury reduc-
tion potential provided by the seat belts and
body structure.
The SABICs deploy downward, covering the
side windows. An inflating SABIC pushes the
outside edge of the trim out of the way and
covers the window. The SABICs inflate with
enough force to injure occupants if they are notbelted and seated properly, or if items are
positioned in the area where the SABICs inflate.
Children are at an even greater risk of injury
from a deploying air bag.
The SABICs may help reduce the risk of partial
or complete ejection of vehicle occupants
through side windows in certain rollover or side
impact events.
WARNING!
•Your vehicle is equipped with left and right
Supplemental Side Air Bag Inflatable Cur-
tains (SABICs). Do not stack luggage or
other cargo up high enough to block the
deployment of the SABICs. The trim cov-
ering above the side windows where the
SABIC and its deployment path are lo-
cated should remain free from any ob-
structions.
(Continued)
WARNING!(Continued)
•Your vehicle is equipped with SABICs. In
order for the SABICs to work as intended,
do not install any accessory items in your
vehicle which could alter the roof. Do not
add an aftermarket sunroof to your vehicle.
Do not add roof racks that require perma-
nent attachments (bolts or screws) for in-
stallation on the vehicle roof. Do not drill
into the roof of the vehicle for any reason.
The SABICs and SABs (“Side Air Bags”) are
designed to activate in certain side impacts and
certain rollover events. The Occupant Restraint
Controller (“ORC”) determines whether the de-
ployment of the Side Air Bags in a particular
side impact or rollover event is appropriate,
based on the severity and type of collision.
Vehicle damage by itself is not a good indicator
of whether or not Side Air Bags should have
deployed.
Side Air Bags are a supplement to the seat belt
restraint system. Side Air Bags deploy in less
time than it takes to blink your eyes. Occupants,

Brake Warning Light
Red Telltale Light What It Means
Brake Warning Light
This light monitors various brake functions, including brake fluid level and parking brake application. If the brake light turns
on it may indicate that the parking brake is applied, that the brake fluid level is low, or that there is a problem with the
anti-lock brake system reservoir.
If the light remains on when the parking brake has been disengaged, and the fluid level is at the full mark on the master
cylinder reservoir, it indicates a possible brake hydraulic system malfunction or that a problem with the Brake Booster has
been detected by the Anti-Lock Brake System (ABS) / Electronic Stability Control (ESC) system. In this case, the light will
remain on until the condition has been corrected. If the problem is related to the brake booster, the ABS pump will run
when applying the brake, and a brake pedal pulsation may be felt during each stop.
The dual brake system provides a reserve braking capacity in the event of a failure to a portion of the hydraulic system. A
leak in either half of the dual brake system is indicated by the Brake Warning Light, which will turn on when the brake
fluid level in the master cylinder has dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:
The light may flash momentarily during sharp cornering maneuvers, which change fluid level conditions. The vehicle
should have service performed, and the brake fluid level checked.
If brake failure is indicated, immediate repair is necessary.

WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may
have failed. It will take longer to stop the
vehicle. You could have a collision. Have the
vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake
System (ABS) are also equipped with ElectronicBrake Force Distribution (EBD). In the event of
an EBD failure, the Brake Warning Light will turn
on along with the ABS Light. Immediate repair
to the ABS system is required.
Operation of the Brake Warning Light can be
checked by turning the ignition switch from the
OFF position to the ON/RUN position. The light
should illuminate for approximately two sec-
onds. The light should then turn off unless the
parking brake is applied or a brake fault isdetected. If the light does not illuminate, have
the light inspected by an authorized dealer.
The light also will turn on when the parking
brake is applied with the ignition switch in the
ON/RUN position.
NOTE:
This light shows only that the parking brake
is applied. It does not show the degree of
brake application.
Vehicle Security Warning Light — If Equipped
Red Telltale Light What It Means
Vehicle Security Warning Light — If Equipped
This light will flash at a fast rate for approximately 15 seconds when the vehicle security alarm is arming, and then will
flash slowly until the vehicle is disarmed.

Anti-Lock Brake (ABS) Indicator Light
Yellow Telltale Light What It Means
Anti-Lock Brake (ABS) Indicator Light
This light monitors the Anti-Lock Brake System (ABS). The light will turn on when the ignition is placed in the ON/RUN po-
sition and may stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, then the Anti-Lock portion of the brake system is not functioning and
service is required. However, the conventional brake system will continue to operate normally if the brake warning light is
not on.
If the ABS light is on, the brake system should be serviced as soon as possible to restore the benefits of Anti-Lock Brakes.
If the ABS light does not turn on when the ignition is placed in the ON/RUN position, have the light inspected by an autho-
rized dealer.
Low Fuel Warning Indicator Light
Yellow Telltale Light What It Means
Low Fuel Warning Indicator Light
When the fuel level reaches approximately 2.8 gal (10.6 L), this light will turn on and a single chime will sound.

selected gear until another upshift or downshift
is chosen, except as described below:
•The transmission will automatically upshift
when necessary to prevent engine over-
speed.
•The transmission will automatically downshift
as the vehicle slows (to prevent engine lug-
ging) and will display the current gear.
•The transmission will automatically downshift
to first gear when coming to a stop. After a
stop, the driver should manually upshift (+)
the transmission as the vehicle is
accelerated.
•If a requested downshift would cause the
engine to overspeed, that shift will not occur.
•Transmission shifting will be more noticeable
when AutoStick is engaged.
•Heavy Anti-Lock Brake System (ABS) appli-
cation will disengage AutoStick mode.
•The system may revert to automatic shift
mode if a fault or overheat condition is
detected.To disengage AutoStick mode, hold the gear
selector to the right (+) until “D” is once again
displayed in the instrument cluster. You can shift
in or out of the AutoStick mode at any time
without taking your foot off the accelerator
pedal.
WARNING!
Do not downshift for additional engine brak-
ing on a slippery surface. The drive wheels
could lose their grip and the vehicle could
skid, causing a collision or personal injury.
FOUR-WHEEL DRIVE
OPERATION — IF EQUIPPED
This feature provides full time, on-demand,
four–wheel drive (4WD).Where one or more wheels have wheel spin or
if additional traction is needed in sand, deep
snow, or loose traction surfaces, activate the
“4WD LOCK” switch by pulling up once and
releasing. This locks the center coupling allow-
ing more torque to be sent to the rear wheels.
The “4WD Indicator Light” will come on in the
cluster. This can be done on the fly, at any
vehicle speed. To deactivate, simply pull on the
switch one more time. The “4WD Indicator
Light” will then go out.
