lock Ram 3500 Chassis Cab 2018 Repair Manual

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 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.
• Only use a rear-facing child restraint in a vehicle
with a rear seat.
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.
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.
192 SAFETY

SABICs (if equipped with SABICs) may help reduce the
risk of head and other injuries to front and rear seat
outboard occupants in certain side impacts, in addition to
the injury reduction potential provided by the seat belts
and body structure.
The SABIC deploys downward, covering the side windows.
An inflating SABIC pushes the outside edge of the headliner
out of the way and covers the window. The SABICs inflate
with enough force to injure occupants if they are not belted
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 (if equipped with SABICs) may help reduce
the risk of partial or complete ejection of vehicle occupants
through side windows in certain side impact events.
WARNING!
•Do not mount equipment, or stack luggage or other
cargo up high enough to block the deployment of the
SABICs. The trim covering above the side windows
where the SABIC and its deployment path are lo-
cated should remain free from any obstructions.
(Continued)
WARNING! (Continued)
•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 permanent attachments (bolts or screws) for
installation on the vehicle roof. Do not drill into the
roof of the vehicle for any reason.
Side Impacts
The Side Air Bags are designed to activate in certain side
impacts. The Occupant Restraint Controller (ORC) deter-
mines whether the deployment of the Side Air Bags in a
particular impact event is appropriate, based on the sever-
ity 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 Side Air Bags
on the impact side of the vehicle during impacts that
require Side Air Bag occupant protection. In side impacts,
the Side Air Bags deploy independently; a left side impact
deploys the left Side Air Bags only and a right-side impact
deploys the right Side Air Bags only. Vehicle damage by
itself is not a good indicator of whether or not Side Air
Bags should have deployed.

SAFETY 199

Enhanced Accident Response System
In the event of an impact, if the communication network
remains intact, and the power remains intact, depending
on the nature of the event, the ORC will determine whether
to have the Enhanced Accident Response System perform
the following functions:
•Cut off fuel to the engine.
• Flash hazard lights as long as the battery has power or
until the hazard light button is pressed. The hazard
lights can be deactivated by pressing the hazard light
button.
• Turn on the interior lights, which remain on as long as
the battery has power.
• Unlock the power door locks.
Enhanced Accident Response System Reset
Procedure
In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be
changed from ignition START or ON/RUN to ignition OFF.
Carefully check the vehicle for fuel leaks in the engine
compartment and on the ground near the engine compart-
ment and fuel tank before resetting the system and starting
the engine.
Maintaining Your Air Bag System
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 components or wiring, in-
cluding adding any kind of badges or stickers to the
steering wheel hub trim cover or the upper right side
of the instrument panel. Do not modify the front
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 accidentally or may
not function properly if modifications 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 your authorized

not use that outboard position. If a child seat in the center
position blocks the outboard LATCH anchors or seat belt,
do not install a child seat in that outboard position.
WARNING!
Never use the same lower anchorage to attach more
than one child restraint. Please refer to “To Install A
LATCH-Compatible Child Restraint” for typical instal-
lation instructions.
Always follow the directions of the child restraint manu-
facturer when installing your child restraint. Not all child
restraint systems will be installed as described here.
To Install A LATCH-Compatible Child Restraint
If the selected seating position has a Switchable Automatic
Locking Retractor (ALR) seat belt, stow the seat belt,
following the instructions below. See the section “Installing
Child Restraints Using the Vehicle Seat Belt” to check what
type of seat belt each seating position has.
1. Loosen the adjusters on the lower straps and on the tether strap of the child seat so that you can more easily
attach the hooks or connectors to the vehicle anchor-
ages.
2. Place the child seat between the lower anchorages for that seating position. For some second row seats, you
may need to recline the seat and / or raise the head
restraint to get a better fit. If the rear seat can be moved

SAFETY 217

forward and rearward in the vehicle, you may wish to
move it to its rear-most position to make room for the
child seat. You may also move the front seat forward to
allow more room for the child seat.
3. Attach the lower hooks or connectors of the child restraint to the lower anchorages in the selected seating
position.
4. If the child restraint has a tether strap, connect it to the top tether anchorage. See the section “Installing Child
Restraints Using the Top Tether Anchorage” for direc-
tions to attach a tether anchor.
5. Tighten all of the straps as you push the child restraint rearward and downward into the seat. Remove slack in
the straps according to the child restraint manufactur-
er ’s instructions.
6. Test that the child restraint is installed tightly by pulling back and forth on the child seat at the belt path. It
should not move more than 1 inch (25.4 mm) in any
direction.
How To Stow An Unused Switchable-ALR (ALR)
Seat Belt:
When using the LATCH attaching system to install a child
restraint, stow all ALR seat belts that are not being used by other occupants or being used to secure child restraints. An
unused belt could injure a child if they play with it and
accidentally lock the seat belt retractor. Before installing a
child restraint using the LATCH system, buckle the seat
belt behind the child restraint and out of the child’s reach.
If the buckled seat belt interferes with the child restraint
installation, instead of buckling it behind the child re-
straint, route the seat belt through the child restraint belt
path and then buckle it. Do not lock the seat belt. Remind
all children in the vehicle that the seat belts are not toys and
that they should not play with them.
WARNING!
•
Improper installation of a child restraint to the
LATCH anchorages can lead to failure of the re-
straint. The child could be badly injured or killed.
Follow the child restraint manufacturer ’s directions
exactly when installing an infant or child restraint.
• Child restraint anchorages are designed to withstand
only those loads imposed by correctly-fitted child
restraints. Under no circumstances are they to be
used for adult seat belts, harnesses, or for attaching
other items or equipment to the vehicle.

Installing Child Restraints Using The Vehicle Seat
Belt
Child restraint systems are designed to be secured in
vehicle seats by lap belts or the lap belt portion of a
lap/shoulder belt.
WARNING!
•Improper installation or failure to properly secure a
child restraint can lead to failure of the restraint. The
child could be badly injured or killed.
• Follow the child restraint manufacturer ’s directions
exactly when installing an infant or child restraint.
Regular Cab Only
The seat belts in the passenger seating positions are
equipped with a Switchable Automatic Locking Retractor
(ALR) that is designed to keep the lap portion of the seat
belt tight around the child restraint so that it is not
necessary to use a locking clip. The ALR retractor can be
“switched” into a locked mode by pulling all of the
webbing out of the retractor and then letting the webbing
retract back into the retractor. If it is locked, the ALR will
make a clicking noise while the webbing is pulled back into
the retractor. Refer to the “Automatic Locking Mode” description in “Switchable Automatic Locking Retractors
(ALR)” under “Occupant Restraint Systems” for additional
information on ALR.
Crew Cab: Split Bench And Full Bench
The seat belts in the passenger seating positions are
equipped with either a Switchable Automatic Locking
Retractor (ALR) or a cinching latch plate or both. Both
types of seat belts are designed to keep the lap portion of
the seat belt tight around the child restraint so that it is not
necessary to use a locking clip. The ALR retractor can be
“switched” into a locked mode by pulling all of the
webbing out of the retractor and then letting the webbing
retract back into the retractor. If it is locked, the ALR will
make a clicking noise while the webbing is pulled back into
the retractor. Refer to the “Automatic Locking Mode”
description in “Switchable Automatic Locking Retractors
(ALR)” under “Occupant Restraint Systems” for additional
information on ALR. The cinching latch plate is designed to

SAFETY 221

1.For Crew Cab Models
Place the child seat in the center of the seating position. For
some second row seats, you may need to recline the seat
and/or raise the head restraint to get a better fit. If the rear
seat can be moved forward and rearward in the vehicle,
you may wish to move it to its rear-most position to make
room for the child seat. You may also move the front seat
forward to allow more room for the child seat.
For Regular Cab Models
Place the child seat in the center of the seating position.
Move the vehicle seat as far rearward as possible to keep
the child as far from the advanced passenger air bag as
possible.
2. Pull enough of the seat belt webbing from the retractor to pass it through the belt path of the child restraint. Do
not twist the belt webbing in the belt path.
3. Slide the latch plate into the buckle until you hear a “click.”
4. Pull on the webbing to make the lap portion tight against the child seat.
5. To lock the seat belt, pull down on the shoulder part of the belt until you have pulled all the seat belt webbing out of the retractor. Then, allow the webbing to retract
back into the retractor. As the webbing retracts, you will
hear a clicking sound. This means the seat belt is now in
the Automatic Locking mode.
6. Try to pull the webbing out of the retractor. If it is locked, you should not be able to pull out any webbing.
If the retractor is not locked, repeat step 5.
7. Finally, pull up on any excess webbing to tighten the lap portion around the child restraint while you push the
child restraint rearward and downward into the vehicle
seat.
8. If the child restraint has a top tether strap and the seating position has a top tether anchorage, connect the
tether strap to the anchorage and tighten the tether
strap. See the section “Installing Child Restraints Using
the Top Tether Anchorage” for directions to attach a
tether anchor.
9. Test that the child restraint is installed tightly by pulling back and forth on the child seat at the belt path. It
should not move more than 1 inch (25.4 mm) in any
direction.
Any seat belt system will loosen with time, so check the
belt occasionally, and pull it tight if necessary.
