ABS JEEP WRANGLER 2016 JK / 3.G Owners Manual

To Disarm The System
To disarm the Vehicle Security Alarm, you will need to
push the UNLOCK button on the RKE transmitter, or
turn the ignition switch to the ON/RUN position. If
something has triggered the Vehicle Security Alarm in
your absence, the horn will sound three times, and 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; however, you can create conditions where the
Vehicle Security Alarm will arm unexpectedly. If you
remain in the vehicle and lock the doors with the RKE
transmitter, once the Vehicle Security 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 transmitter to disarm the Vehicle
Security Alarm. You may also accidentally disarm the
Vehicle Security Alarm by unlocking the driver’s doorwith the key and then locking it. The door will be locked
but the Vehicle Security Alarm will not arm.
NOTE:
•
Unlocking the doors with the manual door lock plung-
ers or the driver’s door lock cylinder will not disarm
the Vehicle Security Alarm.
• When the Vehicle Security Alarm is armed, the interior
power door lock switches will not unlock the doors.
ILLUMINATED ENTRY — IF EQUIPPED
The courtesy lights will turn on when you use the
Remote Keyless Entry (RKE) transmitter to unlock the
doors or open any door.
This feature also turns on the approach lighting in the
outside mirrors (if equipped). Refer to “Mirrors” in
“Understanding The Features Of Your Vehicle” for fur-
ther information.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 21

Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the
driver and front passenger, and position the front occu-
pants for improved interaction 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, stereos, citizen band
radios, etc.
Supplemental Seat-Mounted Side Air Bags (SABs)
Your vehicle is equipped with Supplemental Seat-
Mounted Side Air Bags (SABs) that are located in the
outboard side of the front seats. The SABs are marked
with a “SRS AIRBAG” or “AIRBAG” label sewn into the outboard side of the seats. The SABs may help to reduce
the risk of occupant injury during certain side impacts, 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.
SABs are designed to activate in certain side impacts. The
Occupant Restraint Controller (“ORC”) determines
whether the deployment of the SAB in a particular
impact event is appropriate, based on the severity and
type of collision. The side impact sensors aid the ORC in
determining the appropriate response to impact events. The system is calibrated to deploy the SAB on the impact
side of the vehicle during impacts that require SAB
occupant protection. In side impacts, the SABs deploy
independently; a left side impact deploys the left SAB
only and a right side impact deploys the right side SAB
only. Vehicle damage by itself is not a good indicator of
whether or not SABs should have deployed.
The SABs will not deploy in all side collisions, including
some collisions at certain angles, or some side collisions
that do not impact the area of the passenger compartment.
SABs are a supplement to the seat belt restraint system.
SABs deploy in less time than it takes to blink your eyes.
Occupants, including children, who are up against or very
close to SABs can be seriously injured or killed. Occupants,
including children, should never lean on or sleep against
the door, side windows, or area where the SABs inflate,
even if they are in an infant or child restraint.
68 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Seat belts (and child restraints where appropriate) are
necessary for your protection in all collisions. They also
help keep you in position, away from an inflating SAB.
To get the best protection from the SABs, occupants must
wear their seat belts properly and sit upright with their
backs against the seats. Children must be properly re-
strained in a child restraint or booster seat that is
appropriate for the size of the child.
WARNING!
•SABs need room to inflate. Do not lean against the
door or window. Sit upright in the center of the seat.
• Being too close to the SABs during deployment
could cause you to be severely injured or killed.
WARNING! (Continued)
•Relying on the SABs alone could lead to more
severe injuries in a collision. The SABs work with
your seat belt to restrain you properly. In some
collisions, SABs won’t deploy at all. Always wear
your seat belt even though you have SABs.
NOTE: Air bag covers may not be obvious to you, but
they will open during air bag deployment.
If A Deployment Occurs
The Advanced Front Air Bags are designed to deflate
immediately after deployment.
NOTE: Front and/or side air bags will not deploy in all
collisions. This does not mean something is wrong with
the air bag system.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 69

Brake Warning Light
Red TelltaleLight What It Means
United States
Canada
Brake Warning Light
This light monitors various brake functions, including brake fluid level and parking brake ap-
plication. 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.
318 UNDERSTANDING YOUR INSTRUMENT PANEL

The dual brake system provides a reserve braking capac-
ity 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 condi-
tions. 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 Electronic Brake 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 ap-
proximately two seconds. The light should then turn off
unless the parking brake is applied or a brake fault is
detected. 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.

Anti-Lock Brake (ABS) Indicator Light
Yellow TelltaleLight 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 igni-
tion switch is placed in the ON/RUN position 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 switch is
placed in the ON/RUN position, have the light inspected by an authorized dealer.

STARTING AND OPERATING 431

In the event power assist is lost for any reason (for
example, repeated brake applications with the engine
OFF) the brakes will still function. The effort required to
brake the vehicle will be much greater than that required
with the power system operating.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced Electronic
Brake Control system (EBC). This system includes Elec-
tronic Brake Force Distribution (EBD), Anti-Lock Brake
System (ABS), Brake Assist System (BAS), Hill Start
Assist (HSA), Traction Control System (TCS), Electronic
Stability Control (ESC), and Electronic Roll Mitigation
(ERM). These systems work together to enhance both
vehicle stability and control in various driving condi-
tions.
Your vehicle may also be equipped with Trailer Sway
Control (TSC) and Hill Descent Control (HDC).
Electronic Brake Force Distribution (EBD)
This function manages the distribution of the braking
torque between the front and rear axles by limiting
braking pressure to the rear axle. This is done to prevent
overslip of the rear wheels to avoid vehicle instability,
and to prevent the rear axle from entering ABS before the
front axle.
Brake System Warning Light
The red “Brake System Warning Light” will turn on when
the ignition switch is turned to the ON position and may
stay on for as long as four seconds.
If the “Brake System Warning Light” remains on or
comes on while driving, it indicates that the brake system
is not functioning properly and that immediate service is
required. If the “Brake System Warning Light” does not
come on when the ignition switch is turned to the ON
position, have the light repaired as soon as possible.

STARTING AND OPERATING 481

Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides increased
vehicle stability and brake performance under most
braking conditions. The system automatically prevents
wheel lock, and enhances vehicle control during braking.
The ABS performs a self-check cycle to ensure that the
ABS is working properly each time the vehicle is started
and driven. During this self-check you may hear a slight
clicking sound as well as some related motor noises.
ABS is activated during braking when the system detects
one or more wheels begins to lock. Road conditions such as
ice, snow, gravel, bumps, railroad tracks, loose debris, or
panic stops may increase the likelihood of ABS activation(s).
You also may experience the following when ABS acti-
vates:
•The ABS motor noise (it may continue to run for a
short time after the stop). •
The clicking sound of solenoid valves.
• Brake pedal pulsations.
• A slight drop of the brake pedal at the end of the stop.
These are all normal characteristics of ABS.
WARNING!
• The ABS contains sophisticated electronic equip-
ment that may be susceptible to interference
caused by improperly installed or high output
radio transmitting equipment. This interference
can cause possible loss of anti-lock braking capa-
bility. Installation of such equipment should be
performed by qualified professionals.
• Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to a collision.
Pumping makes the stopping distance longer. Just
