2018 Ram 3500 Chassis Cab lock

NOTE:It is particularly important for you to check the tire
pressure in all of the tires on your vehicle monthly and to
maintain the proper pressure.
The TPIS consists of the following components:
• Receiver module
• Four TPM sensors (Single Rear Wheel [SRW] applica-
tions)
• Six TPM sensors (Dual Rear Wheel [DRW] applications)
• Pressure display in the instrument cluster display.
The TPIS system will display all four (Single Rear Wheel
[SRW] applications) or six (Dual Rear Wheel [DRW] appli-
cations) tire pressure values in the instrument cluster
display.
If a system fault is detected, the instrument cluster will
display a SERVICE TPM SYSTEM message for a mini-
mum of five seconds and then display dashes (- -) in place
of the pressure value to indicate which sensor is not being
received.
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault no
longer exists, the SERVICE TPM SYSTEM message willno longer be displayed, and a pressure value will display
in place of the dashes. A system fault can occur due to any
of the following:
•
Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors.
• Installing aftermarket window tinting that contains ma-
terials that may block radio wave signals.
• Accumulation of snow or ice around the wheels or
wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM sensors.

178 SAFETY

Lap/Shoulder Belts
All seating positions except the Crew Cab front center
seating position have combination lap/shoulder belts.
The seat belt webbing retractor will lock only during very
sudden stops or collisions. This feature allows the shoulder
part of the seat belt to move freely with you under normal
conditions. However, in a collision the seat belt will lock
and reduce your risk of striking the inside of the vehicle or
being thrown out of the vehicle.
WARNING!
•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, the air bags won’t deploy at all. Always
wear your seat belt even though you have air bags.
• In a collision, you and your passengers can suffer
much greater injuries if you are not properly buckled
up. You can strike the interior of your vehicle or
other passengers, or you can be thrown out of the
vehicle. Always be sure you and others in your
vehicle are buckled up properly.
(Continued)
WARNING! (Continued)
•It is dangerous to ride in a cargo area, inside or
outside of a vehicle. In a collision, people riding in
these areas are more likely to be seriously injured or
killed.
• Do not allow people to ride in any area of your
vehicle that is not equipped with seats and seat belts.
• Be sure everyone in your vehicle is in a seat and
using a seat belt properly. Occupants, including the
driver, should always wear their seat belts whether
or not an air bag is also provided at their seating
position to minimize the risk of severe injury or
death in the event of a crash.
• Wearing your seat belt incorrectly could make your
injuries in a collision much worse. You might suffer
internal injuries, or you could even slide out of the
seat belt. Follow these instructions to wear your seat
belt safely and to keep your passengers safe, too.
• Two people should never be belted into a single seat
belt. People belted together can crash into one an-
other in a collision, hurting one another badly. Never
use a lap/shoulder belt or a lap belt for more than one
person, no matter what their size.
182 SAFETY

As a guide, if you are shorter than average, you will prefer
the shoulder belt anchorage in a lower position, and if you
are taller than average, you will prefer the shoulder belt
anchorage in a higher position. After you release the
anchorage button, try to move it up or down to make sure
that it is locked in position.NOTE:
The adjustable upper shoulder belt anchorage is
equipped with an Easy Up feature. This feature allows the
shoulder belt anchorage to be adjusted in the upward
position without pushing or squeezing the release button.
To verify the shoulder belt anchorage is latched, pull
downward on the shoulder belt anchorage until it is locked
into position.
WARNING!
• Wearing your seat belt incorrectly could make your
injuries in a collision much worse. You might suffer
internal injuries, or you could even slide out of the
seat belt. Follow these instructions to wear your seat
belt safely and to keep your passengers safe, too.
• Position the shoulder belt across the shoulder and
chest with minimal, if any slack so that it is comfort-
able and not resting on your neck. The retractor will
withdraw any slack in the shoulder belt.
• Misadjustment of the seat belt could reduce the
effectiveness of the safety belt in a crash.

186 SAFETY

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.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 aclick.

SAFETY 191

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

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
