2023 JEEP GRAND CHEROKEE wiring

STARTING AND OPERATING193
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake system
or vacuum system of your vehicle with that of
the trailer. This could cause inadequate braking
and possible personal injury.
An electronically actuated trailer brake
controller is required when towing a trailer with
electronically actuated brakes. When towing a
trailer equipped with a hydraulic surge actuated
brake system, an electronic brake controller is
not required.
Trailer brakes are recommended for trailers
over 1,000 lb (453 kg) and required for trailers
in excess of 2,000 lb (907 kg).
Towing Requirements — Trailer Lights And
Wiring
Whenever pulling a trailer, regardless of the trailer
size, stop lights and turn signals on the trailer are
required for motoring safety.
The Trailer Tow Package may include a four- and
seven-pin wiring harness. Use a factory approved
trailer harness and connector.
NOTE:Do not cut or splice wiring into the vehicle’s wiring
harness.
The electrical connections are all complete to the
vehicle but you must mate the harness to a trailer
connector. Refer to the following illustrations.
NOTE:
Disconnect the trailer wiring connector from the
vehicle (or any other device plugged into
vehicle’s electrical connectors) before
launching a boat into water.
Be sure to reconnect once clear from water
area.

Four-Pin Connector

WARNING!
Do not connect trailer brakes to your vehicle's
hydraulic brake lines. It can overload your
brake system and cause it to fail. You might
not have brakes when you need them and
could have an accident.
Towing any trailer will increase your stopping
distance. When towing, you should allow for
additional space between your vehicle and the
vehicle in front of you. Failure to do so could
result in an accident.
CAUTION!

If the trailer weighs more than 1,000 lb (453 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.

SAFETY277
Third Row Stow Clip — If Equipped
Six And Seven Passenger Only
Your vehicle may be equipped with a stow clip on
the lower trim behind the third row. This clip is used
to hold the seat belt out of the path of the third row
seat back when it is being folded and opened. Only
place the seat belt webbing in this clip while folding
and opening the seat. Do not leave the webbing
behind the clip when using the belt to restrain an
occupant.

SUPPLEMENTAL RESTRAINT SYSTEMS
(SRS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on others. If
you are not sure, ask an authorized dealer.
The air bag system must be ready to protect you in
a collision. The Occupant Restraint Controller
(ORC) monitors the internal circuits and
interconnecting wiring associated with the
electrical Air Bag System Components. Your
vehicle may be equipped with the following Air Bag
System Components:
Air Bag System Components
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Knee Impact Bolsters
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Supplemental Knee Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Seat Track Position Sensors
Occupant Classification System
Air Bag Warning Light
The Occupant Restraint Controller (ORC)
monitors the readiness of the electronic
parts of the air bag system whenever the
ignition switch is in the START or ON/RUN
position. If the ignition switch is in the OFF position
or in the ACC position, the air bag system is not on
and the air bags will not inflate.
WARNING!
Do not place the seat belt webbing behind the
third row stow clip when using the seat belt to
restrain an occupant. The seat belt will not be
positioned properly on the occupant and they
could be more seriously injured in an accident
as a result.

286SAFETY
NOTE:Air bag covers may not be obvious in the interior
trim, but they will open during air bag deployment.
Rollover Events
Side Air Bags and seat belt pretensioners are
designed to activate in certain rollover events. The
Occupant Restraint Controller (ORC) determines
whether deployment in a particular 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 and seat
belt pretensioners should have deployed. The Side Air Bags and seat belt pretensioners will
not deploy in all rollover events. The rollover
sensing system determines if a rollover event may
be in progress and whether deployment is
appropriate. In the event the vehicle experiences a
rollover or near rollover event, and deployment is
appropriate, the rollover sensing system will deploy
the side air bags and seat belt pretensioners on
both sides of the vehicle.
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.

If A Deployment Occurs
The front air bags are designed to deflate
immediately after deployment.
NOTE:Front and/or side air bags will not deploy in all colli -
sions. This does not mean something is wrong with
the air bag system.
If you do have a collision which deploys the air
bags, any or all of the following may occur:
The air bag material may sometimes cause
abrasions and/or skin reddening to the occu -
pants as the air bags deploy and unfold. The
abrasions are similar to friction rope burns or
those you might get sliding along a carpet or
gymnasium floor. They are not caused by
contact with chemicals. They are not permanent
and normally heal quickly. However, if you
haven’t healed significantly within a few days, or
if you have any blistering, see your doctor imme -
diately.
WARNING!
Side Air Bags 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 Side Air Bags during
deployment could cause you to be severely
injured or killed.
Relying on the Side Air Bags alone could lead
to more severe injuries in a collision. The Side
Air Bags work with your seat belt to restrain
you properly. In some collisions, Side Air Bags
won’t deploy at all. Always wear your seat belt
even though you have Side Air Bags.

(Continued)
After an accident, if the vehicle will not start after
performing the reset procedure, the vehicle must
be towed to an authorized dealer to be inspected
and to have the Enhanced Accident Response
System reset.
Maintaining Your Air Bag System
Event Data Recorder (EDR)
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR is to
record, in certain crash or near crash-like
situations, such as an air bag deployment or hitting
a road obstacle, data that will assist in
understanding how a vehicle’s systems performed.
The EDR is designed to record data related to
vehicle dynamics and safety systems for a short
period of time, typically 30 seconds or less. The
EDR in this vehicle is designed to record such data
as:
How various systems in your vehicle were oper
-
ating;
Whether or not the driver and passenger safety
belts were buckled/fastened;
How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
How fast the vehicle was traveling.
These data can help provide a better
understanding of the circumstances in which
crashes and injuries occur.
WARNING!
Modifications to any part of the air bag system
could cause it to fail when you need it. You
could be injured if the air bag system is not
there to protect you. Do not modify the compo -
nents or wiring, including adding any kind of
badges or stickers to the steering wheel hub
trim cover or the upper passenger side of the
instrument panel. Do not modify the front
fascia/bumper, vehicle body structure, or add
aftermarket side steps or running boards.
It is dangerous to try to repair any part of the
air bag system yourself. Be sure to tell anyone
who works on your vehicle that it has an air
bag system.
Do not attempt to modify any part of your air
bag system. The air bag may inflate acciden -
tally or may not function properly if modifica -
tions are made. Take your vehicle to an
authorized dealer for any air bag system
service. If your seat, including your trim cover
and cushion, needs to be serviced in any way
(including removal or loosening/tightening of
seat attachment bolts), take the vehicle to an
authorized dealer. Only manufacturer
approved seat accessories may be used. If it is
necessary to modify the air bag system for
persons with disabilities, contact an autho -
rized dealer.
