Jeep Compass (2019 year). Manual — part 12

Seat Belt Pretensioner

The front outboard seat belt system is equipped with
pretensioning devices that are designed to remove slack
from the seat belt in the event of a collision. These devices
may improve the performance of the seat belt by removing
slack from the seat belt early in a collision. Pretensioners
work for all size occupants, including those in child
restraints.

NOTE:

These devices are not a substitute for proper seat

belt placement by the occupant. The seat belt still must be
worn snugly and positioned properly.

The pretensioners are triggered by the Occupant Restraint
Controller (ORC). Like the air bags, the pretensioners are
single use items. A deployed pretensioner or a deployed air
bag must be replaced immediately.

Energy Management Feature

The front outboard seat belt system is equipped with an
Energy Management feature that may help further reduce
the risk of injury in the event of a collision. The seat belt
system has a retractor assembly that is designed to release
webbing in a controlled manner.

Switchable Automatic Locking Retractors (ALR)

The seat belts in the passenger seating positions are
equipped with a Switchable Automatic Locking Retractor
(ALR) which is used to secure a child restraint system. For
additional information, refer to “Installing Child Restraints
Using The Vehicle Seat Belt” under the “Child Restraints”
section of this manual. The figure below illustrates the
locking feature for each seating position.

ALR — Switchable Automatic Locking Retractor

180

SAFETY

If the passenger seating position is equipped with an ALR
and is being used for normal usage, only pull the seat belt
webbing out far enough to comfortably wrap around the
occupant’s mid-section so as to not activate the ALR. If the
ALR is activated, you will hear a clicking sound as the seat
belt retracts. Allow the webbing to retract completely in
this case and then carefully pull out only the amount of
webbing necessary to comfortably wrap around the occu-
pant’s mid-section. Slide the latch plate into the buckle
until you hear a

⬙click.⬙

In Automatic Locking Mode, the shoulder belt is automati-
cally pre-locked. The seat belt will still retract to remove
any slack in the shoulder belt. Use the Automatic Locking
Mode anytime a child restraint is installed in a seating
position that has a seat belt with this feature. Children 12
years old and under should always be properly restrained
in the rear seat of a vehicle with a rear seat.

WARNING!

• Never place a rear-facing child restraint in front of an

air bag. A deploying passenger front air bag can
cause death or serious injury to a child 12 years or
younger, including a child in a rear-facing child
restraint.

• Never install a rear-facing child restraint in the front

seat of a vehicle. Only use a rear-facing child re-
straint in the rear seat. If the vehicle does not have a
rear seat, do not transport a rear-facing child restraint
in that vehicle.

How To Engage The Automatic Locking Mode

1. Buckle the combination lap and shoulder belt.

2. Grasp the shoulder portion and pull downward until

the entire seat belt is extracted.

3. Allow the seat belt to retract. As the seat belt retracts,

you will hear a clicking sound. This indicates the seat
belt is now in the Automatic Locking Mode.

SAFETY

181

How To Disengage The Automatic Locking Mode

Unbuckle the combination lap/shoulder belt and allow it
to retract completely to disengage the Automatic Locking
Mode and activate the vehicle sensitive (emergency) lock-
ing mode.

WARNING!

• The seat belt assembly must be replaced if the

switchable Automatic Locking Retractor (ALR) fea-
ture or any other seat belt function is not working
properly when checked according to the procedures
in the Service Manual.

• Failure to replace the seat belt assembly could in-

crease the risk of injury in collisions.

• Do not use the Automatic Locking Mode to restrain

occupants who are wearing the seat belt or children
who are using booster seats. The locked mode is only
used to install rear-facing or forward-facing child
restraints that have a harness for restraining the
child.

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) moni-
tors the internal circuits and interconnecting wiring asso-
ciated 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

182

SAFETY

• Supplemental Knee Air Bags
• Front and Side Impact Sensors
• Seat Belt Pretensioners
• Seat Track Position Sensors
• Occupant Classification System

Air Bag Warning Light

The 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.

The ORC contains a backup power supply system that may
deploy the air bag system 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 switch is first in the
ON/RUN position. After the self-check, the Air Bag Warn-
ing 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 diagnos-
tics also record the nature of the malfunction. While the air
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 switch is first in
the ON/RUN position.

• The Air Bag Warning Light remains on after the four to

eight-second interval.

• The Air Bag Warning Light comes on intermittently or

remains on while driving.

SAFETY

183

NOTE:

If the speedometer, tachometer, or any engine

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 service the air bag system
immediately.

WARNING!

Ignoring the Air Bag Warning Light in your instrument
panel could mean you won’t have the air bag system to
protect you in a collision. If the light does not come on
as a bulb check when the ignition is first turned on,
stays on after you start the vehicle, or if it comes on as
you drive, have an authorized dealer service the air bag
system immediately.

Redundant Air Bag Warning Light

If a fault with the Air Bag Warning Light is detected, which

could affect the Supplemental Restraint System
(SRS), the Redundant Air Bag Warning Light will
illuminate on the instrument panel. The Redun-
dant Air Bag Warning Light will stay on until the

fault is cleared. In addition, a single chime will sound to
alert you that the Redundant Air Bag Warning Light has
come on and a fault has been detected. If the Redundant
Air Bag Warning Light comes on intermittently or remains
on while driving have an authorized dealer service the
vehicle immediately.

For additional information regarding the Redundant Air
Bag Warning Light refer to “Getting To Know Your Instru-
ment Panel” section of this manual.

184

SAFETY

Front Air Bags

This vehicle has front air bags and lap/shoulder belts for both
the driver and front passenger. The front air bags are a
supplement to the seat belt restraint systems. The driver front
air bag is mounted in the center of the steering wheel. The
passenger front air bag is mounted in the instrument panel,
above the glove compartment. The words “SRS AIRBAG” or
“AIRBAG” are embossed on the air bag covers.

WARNING!

• Being too close to the steering wheel or instrument

panel during front air bag deployment could cause
serious injury, including death. Air bags need room
to inflate. Sit back, comfortably extending your arms
to reach the steering wheel or instrument panel.

• Never place a rear-facing child restraint in front of an

air bag. A deploying passenger front air bag can
cause death or serious injury to a child 12 years or
younger, including a child in a rear-facing child
restraint.

• Never install a rear-facing child restraint in the front

seat of a vehicle. Only use a rear-facing child re-
straint in the rear seat. If the vehicle does not have a
rear seat, do not transport a rear-facing child restraint
in that vehicle.

Driver And Passenger Front Air Bag Features

The Advanced Front Air Bag system has multistage driver
and front passenger air bags. This system provides output
appropriate to the severity and type of collision as deter-
mined by the Occupant Restraint Controller (ORC), which
may receive information from the front impact sensors (if
equipped) or other system components.

SAFETY

185

The first stage inflator is triggered immediately during an
impact that requires air bag deployment. A low energy
output is used in less severe collisions. A higher energy
output is used for more severe collisions.

This vehicle may be equipped with a driver and/or front
passenger seat belt buckle switch that detects whether the
driver or front passenger seat belt is buckled. The seat belt
buckle switch may adjust the inflation rate of the Ad-
vanced Front Air Bags.

This vehicle may be equipped with driver and/or front
passenger seat track position sensors that may adjust the
inflation rate of the Advanced Front Air Bags based upon
seat position.

This vehicle is equipped with a right front passenger
Occupant Classification System (“OCS”) that is designed to
provide Passenger Advanced Front Air Bag output appro-
priate to the occupant’s seated weight input, as determined
by the OCS.

WARNING!

• No objects should be placed over or near the air bag

on the instrument panel or steering wheel because
any such objects could cause harm if the vehicle is in
a collision severe enough to cause the air bag to
inflate.

• Do not put anything on or around the air bag covers

or attempt to open them manually. You may damage
the air bags and you could be injured because the air
bags may no longer be functional. The protective
covers for the air bag cushions are designed to open
only when the air bags are inflating.

• Relying on the air bags alone could lead to more

severe injuries in a collision. The air bags work with
your seat belt to restrain you properly. In some
collisions, air bags won’t deploy at all. Always wear
your seat belts even though you have air bags.

186

SAFETY

Front Air Bag Operation

Front Air Bags are designed to provide additional protec-
tion by supplementing the seat belts. Front air bags are not
expected to reduce the risk of injury in rear, side, or
rollover collisions. The front air bags will not deploy in all
frontal collisions, including some that may produce sub-
stantial vehicle damage — for example, some pole colli-
sions, truck underrides, and angle offset collisions.

On the other hand, depending on the type and location of
impact, front air bags may deploy in crashes with little
vehicle front-end damage but that produce a severe initial
deceleration.

Because air bag sensors measure vehicle deceleration over
time, vehicle speed and damage by themselves are not
good indicators of whether or not an air bag should have
deployed.

Seat belts are necessary for your protection in all collisions,
and also are needed to help keep you in position, away
from an inflating air bag.

When the ORC detects a collision requiring the front air
bags, it signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the front air bags.

The steering wheel hub trim cover and the upper passen-
ger side of the instrument panel separate and fold out of
the way as the air bags inflate to their full size. The front air
bags fully inflate in less time than it takes to blink your
eyes. The front air bags then quickly deflate while helping
to restrain the driver and front passenger.

Occupant Classification System (OCS) — Front
Passenger Seat

The OCS is part of a Federally regulated safety system for
this vehicle. It is designed to provide Passenger Advanced
Front Air Bag output appropriate to the occupant’s seated
weight, as determined by the OCS.

The Occupant Classification System (OCS) consists of the
following:
• Occupant Restraint Controller (ORC)
• Occupant Classification Module (OCM) and Sensor lo-

cated in the front passenger seat

• Air Bag Warning Light

5

SAFETY

187

Occupant Classification Module (OCM) And Sensor

The Occupant Classification Module (OCM) is located
underneath the front passenger seat. The Sensor is located
beneath the passenger seat cushion foam. Any weight on
the seat will be sensed by the Sensor. The OCM uses input
from the Sensor to determine the front passenger’s most
probable classification. The OCM communicates this infor-
mation to the ORC. The ORC may reduce the inflation rate
of the Passenger Advanced Front Air Bag deployment
based on occupant classification. In order for the OCS to
operate as designed, it is important for the front passenger
to be seated properly and properly wearing the seat belt.

The OCS will NOT prevent deployment of the Passenger
Advanced Front Air Bag. The OCS may reduce the inflation
rate of the Passenger Advanced Front Air Bag if the OCS
estimates that:
• The front passenger seat is unoccupied or has very light

objects on it; or

• The front passenger seat is occupied by a small passen-

ger, including a child; or

• The front passenger seat is occupied by a rear-facing

child restraint; or

• The front passenger is not properly seated or his or her

weight is taken off of the seat for a period of time.

ger seat.

188

SAFETY

WARNING!

• Never place a rear-facing child restraint in front of an

air bag. A deploying passenger front air bag can
cause death or serious injury to a child 12 years or
younger, including a child in a rear-facing child
restraint.

• Never install a rear-facing child restraint in the front

seat of a vehicle. Only use a rear-facing child re-
straint in the rear seat. If the vehicle does not have a
rear seat, do not transport a rear-facing child restraint
in that vehicle.

• Children 12 years or younger should always ride

buckled up in the rear seat of a vehicle with a rear
seat.

The OCS determines the front passenger’s most probable
classification. The OCS estimates the seated weight on the
front passenger seat and where that weight is located. The
OCS communicates the classification status to the ORC.
The ORC uses the classification to determine whether the
Passenger Advanced Front Air Bag inflation rate should be
adjusted.

In order for the OCS to operate as designed, it is important
for the front passenger to be seated properly and properly
wearing the seat belt. Properly seated passengers are:
• Sitting upright
• Facing forward
• Sitting in the center of the seat with their feet comfort-

ably on or near the floor

• Sitting with their back against the seatback and the

seatback in an upright position

Seated Properly

SAFETY

189

Lighter Weight Passengers (Including Small Adults)

When a lighter weight passenger, including a small adult,
occupies the front passenger seat, the OCS may reduce the
inflation rate of the Passenger Advanced Front Air Bag.
This does not mean that the OCS is working improperly.

Do not decrease OR increase the front passenger’s seated
weight on the front passenger seat

The front passenger’s seated weight must be properly
positioned on the front passenger seat. Failure to do so may
result in serious injury or death. The OCS determines the
most probable classification of the occupant that it detects.
The OCS will detect the front passenger’s decreased or
increased seated weight, which may result in an adjusted
inflation rate of the Passenger Advanced Front Air Bag in a
collision. This does not mean that the OCS is working
improperly. Decreasing the front passenger’s seated weight
on the front passenger seat may result in a reduced-power
deployment of the Passenger Advanced Front Air Bag.
Increasing the front passenger’s seated weight on the front
passenger seat may result in a full-power deployment of
the Passenger Advanced Front Air Bag.

Examples of improper front passenger seating include:
• The front passenger’s weight is transferred to another

part of the vehicle (like the door, arm rest or instrument
panel).

• The front passenger leans forward, sideways, or turns to

face the rear of the vehicle.

• The front passenger’s seatback is not in the full upright

position.

• The front passenger carries or holds an object while

seated (e.g., backpack, box, etc.).

• Objects are lodged under the front passenger seat.
• Objects are lodged between the front passenger seat and

center console.

• Accessories that may change the seated weight on the

front passenger seat are attached to the front passenger
seat.

• Anything that may decrease or increase the front pas-

senger’s seated weight.

190

SAFETY

The OCS determines the front passenger’s most probable
classification. If an occupant in the front passenger seat is
seated improperly, the occupant may provide an output
signal to the OCS that is different from the occupant’s
properly seated weight input, for example:

SAFETY

WARNING!

• If a child restraint system, child, small teenager or

adult in the front passenger seat is seated improp-
erly, the occupant may provide an output signal to
the OCS that is different from the occupant’s prop-
erly seated weight input. This may result in serious
injury or death in a collision.

• Always wear your seat belt and sit properly, with the

seatback in an upright position, your back against
the seatback, sitting upright, facing forward, in the
center of the seat, with your feet comfortably on or
near the floor.

• Do not carry or hold any objects (e.g., backpacks,

boxes, etc.) while seated in the front passenger seat.
Holding an object may provide an output signal to
the OCS that is different than the occupant’s prop-
erly seated weight input, which may result in serious
injury or death in a collision.

• Placing an object on the floor under the front pas-

senger seat may prevent the OCS from working
properly, which may result in serious injury or death
in a collision. Do not place any objects on the floor
under the front passenger seat.

The Air Bag Warning Light

in the instrument panel

will turn on whenever the OCS is unable to classify the
front passenger seat status. A malfunction in the OCS
may affect the operation of the air bag system.

If the Air Bag Warning Light

does not come on, or

stays on after you start the vehicle, or it comes on as you
drive, take the vehicle to an authorized dealer for
service immediately.

The passenger seat assembly contains critical OCS compo-
nents that may affect the Passenger Advanced Front Air Bag
inflation. In order for the OCS to properly classify the seated
weight of a front seat passenger, the OCS components must
function as designed. Do not make any modifications to the
front passenger seat components, assembly, or to the seat
cover. If the seat, trim cover, or cushion needs service for any
reason, take the vehicle to an authorized dealer. Only FCA
US LLC approved seat accessories may be used.

The following requirements must be strictly followed:
• Do not modify the front passenger seat assembly or

components in any way.

• Do not use prior or future model year seat covers or

cushions not designated by FCA US LLC for the specific
model being repaired. Always use the correct seat cover
and cushion specified for the vehicle.

5

SAFETY

193

• Do not replace the seat cover or cushion with an

aftermarket seat cover or cushion.

• Do not add a secondary seat cover or mat.
• At no time should any Supplemental Restraint System

(SRS) component or SRS related component or fastener
be modified or replaced with any part except those
which are approved by FCA US LLC.

WARNING!

• Unapproved modifications or service procedures to

the passenger seat assembly, its related components,
seat cover or cushion may inadvertently change the
air bag deployment in case of a frontal collision. This
could result in death or serious injury to the front
passenger if the vehicle is involved in a collision. A
modified vehicle may not comply with required
Federal Motor Vehicle Safety Standards (FMVSS)
and/or Canadian Motor Vehicle Safety Standards
(CMVSS).

• If it is necessary to modify the air bag system for

persons with disabilities, contact an authorized
dealer.

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 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 Driver Knee Air Bag

This vehicle is equipped with a Supplemental Driver Knee
Air Bag mounted in the instrument panel below the
steering column. The Supplemental Driver Knee Air Bag
provides enhanced protection during a frontal impact by
working together with the seat belts, pretensioners, and
front air bags.

Supplemental Side Air Bags

Supplemental Seat-Mounted Side Air Bags (SABs)

This vehicle is equipped with Supplemental Seat-Mounted
Side Air Bags (SABs).

194

SAFETY

Supplemental Seat-Mounted Side Air Bags (SABs) are
located in the outboard side of the front seats. The SABs are
marked with “SRS AIRBAG” or “AIRBAG” on a label or on
the seat trim on 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.
