Tire Fill Alert — If Equipped
This feature notifies the user when the placard tire
pressure is attained while inflating or deflating the
tire.
The customer may choose to disable or enable the
Tire Fill Alert feature through use of the customer
settings in the radio.
NOTE:The Tire Fill Alert feature disables every time the
ignition is placed in the OFF position. The feature
must be re-enabled through the radio each time
the ignition is placed back in the ON/RUN position
Úpage 199.
NOTE:
Only one tire can be filled at a time when using
the Tire Fill Alert system.
The Tire Fill Alert feature cannot be entered if an
existing TPMS fault is set to “active” or if the
system is in deactivation mode (if equipped).
The system will be activated when the TPMS
receiver module detects a change in tire pressure.
The ignition must be in the RUN mode, with the
transmission in PARK (P).
NOTE:It is not required to have the engine running to
enter Tire Fill Alert mode. The hazard lamps will come on to confirm the
vehicle is in Tire Fill Alert mode.
If the hazard lamps do not come on while inflating
the tire, the TPMS sensor may be in a null spot
preventing the TPMS sensor signal from being
received. In this case, the vehicle may need to be
moved either forward or backward slightly to exit
the null spot.
When Tire Fill Alert mode is entered, the tire
pressure display screen will be displayed in the
instrument cluster.
Operation:
The horn will chirp once to let the user know
when to stop filling the tire, when it reaches
recommended pressure.
The horn will chirp three times if the tire is over
-
filled and will continue to chirp every five
seconds if the user continues to inflate the tire.
The horn will chirp once again when enough air
is let out to reach proper inflation level.
The horn will also chirp three times if the tire is
then underinflated and will continue to chirp
every five seconds if the user continues to
deflate the tire.
SELECTABLE TIRE FILL ALERT (STFA) —
IF EQUIPPED
The Selectable Tire Fill Alert (STFA) system is an
optional feature that is included as part of the
normal Tire Fill Alert system. The system is
designed to allow the customer to select a
pressure to inflate or deflate the vehicle's front and
rear axle tires to and to provide feedback to the
customer while inflating or deflating the vehicle's
tires.
In the Selectable Tire Fill Alert application, which is
located in the apps menu of the Uconnect system,
the customer will be able to select a pressure
setting for both the front and rear axle tire
pressures by scrolling through a pressure range
from XX to 15 psi in 1 psi increments for each axle
setting. XX = the vehicle’s cold placard pressure
values for the front and rear axles as shown on the
vehicle placard pressure label.
NOTE:The Tire Fill Alert feature disables every time the
ignition is placed in the OFF position. The feature
must be re-enabled through the radio each time
the ignition is placed back in the ON/RUN position
Ú page 199.

23_DPF_OM_EN_USC_t.book Page 286

SAFETY287
The customer may also store the pressure values
chosen for each axle in the radio as a preset
pressure. The customer will be allowed to store up
to two sets of preset values in the radio for the
front and rear axle pressure values.
Once the customer selects the tire pressures for
the front and rear axles that they want to inflate or
deflate to, they can begin inflating or deflating one
tire at a time.
NOTE:The STFA system will only support inflating or
deflating one tire at a time.
The customer may choose to disable or enable the
STFA feature through use of the TFA settings in the
radio. If STFA appears grayed out it must be turned
on prior to selecting.
In order to use STFA, the Tire Fill Alert feature must
be enabled through the radio Ú page 199.
The system will be activated when the TPMS
receiver module detects a change in tire pressure.
The ignition must be in the RUN mode, with the
transmission in PARK (P).
The hazard lamps will come on to confirm the
vehicle is in Tire Fill Alert mode.
If the hazard lamps do not come on while inflating
or deflating the tire, the TPMS sensor may be in a
null spot preventing the TPMS sensor signal from
being received. In this case, the vehicle may need to be moved either forward or backward slightly to
exit the null spot.
When Tire Fill Alert mode is entered, the tire
pressure display screen will be displayed in the
instrument cluster.
Operation:
The horn will chirp once when the selected pres
-
sure is reached to let the user know when to
stop inflating or deflating the tire.
The horn will chirp three times if the tire is over -
inflated or over deflated and will continue to
chirp every five seconds if the user continues to
inflate or deflate the tire.
The horn will chirp once again when enough air
is added or removed to reach proper selected
pressure level.
Tire Pressure Information System (TPIS)
3500/4500/5500 Series Trucks
Your vehicle may be equipped with a Tire Pressure
Information System (TPIS).
The Tire Pressure Information System (TPIS) uses
wireless technology with wheel rim mounted
electronic sensors to transmit tire pressure levels.
Sensors mounted to each wheel as part of the
valve stem transmit tire pressure readings to the
receiver module.
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 TPMS sensors (Single Rear Wheel (SRW)
applications)
Six TPMS sensors (Dual Rear Wheel (DRW)
applications)
Pressure display in the instrument cluster
The TPIS will display all four (Single Rear Wheel
(SRW) applications) or six (Dual Rear Wheel (DRW)
applications) 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 minimum 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 will no longer be displayed, and
a pressure value will display in place of the dashes.

Installing A Child Restraint With A
Switchable Automatic Locking Retractor
(ALR):
Child restraint systems are designed to be secured
in vehicle seats by lap belts or the lap belt portion
of a lap/shoulder belt.

1.
For Crew Cab Models
Place the child seat in the center of the seating
position. If the second row seat can be re -
clined, you may recline the seat and/or raise
the head restraint (if adjustable) 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
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
Úpage 318 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.
Installing A Child Restraint With A Cinching
Latch Plate (CINCH) — If Equipped:
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.

for cuts, frays, and loose parts. Damaged parts
must be replaced immediately. Do not
disassemble or modify the system.
If your vehicle is involved in a collision, or if you
have questions regarding seat belt or retractor
conditions, take your vehicle to an authorized FCA
dealer or authorized FCA Certified Collision Care
Program facility for inspection.
Air Bag Warning Light
The Air Bag Warning Light will turn on for
four to eight seconds as a bulb check
when the ignition switch is first placed in
ON/RUN. If the light is either not on
during starting, stays on, or turns on while driving,
have the system inspected at an authorized dealer
as soon as possible. After the bulb check, this light
will illuminate with a single chime when a fault with
the Air Bag System has been detected. It will stay
on until the fault is removed. If the light comes on
intermittently or remains on while driving, have an
authorized dealer service the vehicle immediately
Ú page 288.
Defroster
Check operation by selecting the defrost mode and
place the blower control on high speed. You should
be able to feel the air directed against the
windshield. See an authorized dealer for service if
your defroster is inoperable.
Floor Mat Safety Information
Always use floor mats designed to fit your vehicle.
Only use a floor mat that does not interfere with the
operation of the accelerator, brake or clutch
pedals. Only use a floor mat that is securely
attached using the floor mat fasteners so it cannot
slip out of position and interfere with the
accelerator, brake or clutch pedals or impair safe
operation of your vehicle in other ways.
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.
WARNING!WARNING!
It is not possible to know or to predict all of the
possible outcomes if your vehicle’s systems are
breached. It may be possible that vehicle
systems, including safety related systems, could
be impaired or a loss of vehicle control could
occur that may result in an accident involving
serious injury or death.

PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and uneven
wear patterns. Check for stones, nails, glass, or
other objects lodged in the tread or sidewall.
Inspect the tread for cuts and cracks. Inspect
sidewalls for cuts, cracks, and bulges. Check the
lug nuts/bolt torque for tightness. Check the tires
(including spare) for proper cold inflation pressure.
WARNING!
An improperly attached, damaged, folded, or
stacked floor mat, or damaged floor mat
fasteners may cause your floor mat to interfere
with the accelerator, brake, or clutch pedals and
cause a loss of vehicle control. To prevent
SERIOUS INJURY or DEATH:
 ALWAYS securely attach your floor
mat using the floor mat fasteners. DO
NOT install your floor mat upside down
or turn your floor mat over. Lightly pull
to confirm mat is secured using the floor mat
fasteners on a regular basis.
 ALWAYS REMOVE THE EXISTING
FLOOR MAT FROM THE VEHICLE
before installing any other floor mat.
NEVER install or stack an additional
floor mat on top of an existing floor mat.
ONLY install floor mats designed to fit your
vehicle. NEVER install a floor mat that cannot
be properly attached and secured to your
vehicle. If a floor mat needs to be replaced,
only use a FCA approved floor mat for the
specific make, model, and year of your
vehicle.
ONLY use the driver’s side floor mat on the
driver’s side floor area. To check for interfer -
ence, with the vehicle properly parked with the
engine off, fully depress the accelerator, the
brake, and the clutch pedal (if present) to
check for interference. If your floor mat inter -
feres with the operation of any pedal, or is not
secure to the floor, remove the floor mat from
the vehicle and place the floor mat in your
trunk.
ONLY use the passenger’s side floor mat on
the passenger’s side floor area.
ALWAYS make sure objects cannot fall or slide
into the driver’s side floor area when the
vehicle is moving. Objects can become
trapped under accelerator, brake, or clutch
pedals and could cause a loss of vehicle
control.
NEVER place any objects under the floor mat
(e.g., towels, keys, etc.). These objects could
change the position of the floor mat and may
cause interference with the accelerator,
brake, or clutch pedals.
WARNING!
If the vehicle carpet has been removed and
re-installed, always properly attach carpet to
the floor and check the floor mat fasteners are
secure to the vehicle carpet. Fully depress
each pedal to check for interference with the
accelerator, brake, or clutch pedals then
re-install the floor mats.
It is recommended to only use mild soap and
water to clean your floor mats. After cleaning,
always check your floor mat has been properly
installed and is secured to your vehicle using
the floor mat fasteners by lightly pulling mat.

332IN CASE OF EMERGENCY
Dual Rear Wheels
Slots in the wheels will assist in properly orienting
the inner and outer wheels. Align these slots when
assembling the wheels for best access to the tire
valve on the inner wheel. The tires of both dual
wheels must be completely off the ground when
tightening to ensure wheel centering and
maximum wheel clamping.
Dual wheel models require a special heavy-duty lug
nut tightening adapter (included with the vehicle)
to correctly tighten the lug nuts. Also, when it is
necessary to remove and install dual rear wheels,
use a proper vehicle lifting device.
NOTE:When installing a spare tire (if equipped) as part of
a dual rear wheel end combination, the tire
diameter of the two individual tires must be
compared. If there is a significant difference, the
larger tire should be installed in a front location.
The correct direction of rotation for dual tire instal -
lations must also be observed.
It is recommended that wheel stud nuts be kept
torqued to specifications at all times. Torque wheel
stud nuts to specifications at each lubrication
interval Ú page 411.
Wheel Nuts
All wheel nuts should be tightened occasionally to
eliminate the possibility of wheel studs being
sheared or the bolt holes in the wheels becoming elongated. This is especially important during the
first few hundred miles/kilometers of operation to
allow the wheel nuts to become properly set. All
wheel nuts should first be firmly seated against the
wheel. The wheel nuts should then be tightened to
recommended torque. Tighten the wheel nuts to
final torque in increments. Progress around the
bolt circle, tightening the wheel nut opposite to the
wheel nut just previously tightened until final
torque is achieved Ú
page 411.
TO STOW THE FLAT OR SPARE —
I
F EQUIPPED
Refer to Upfitters Body Builder’s Guide for
information on stowing your spare tire (if
equipped).
HUB CAPS/WHEEL COVERS —
I
F EQUIPPED
The hub caps must be removed before raising the
vehicle off the ground. For 3500 Single Rear-Wheel (SRW) models, use
the flat end of the lug wrench to hook and pull off
the hub cap. Find the opening in the hub cap,
insert the lug wrench, and pull off the cap. If you
need to pry against the wheel, protect the wheel
surface.

Lug Wrench Insertion Location — Hub Cap

On 3500 models with Dual Rear-Wheels (DRW),
you must first remove the hub caps—use the
procedure noted for the single rear wheel. For the
wheel covers (wheel skins), insert the flat end of
the lug wrench between the outer edge of the
wheel cover and the wheel. Pry against the wheel
to remove the wheel cover. Repeat this procedure
around the wheel until the cover pops off.
CAUTION!
Use extreme caution when removing the front
and rear wheel covers. Damage can occur to the
center cap and/or the wheel if screwdriver type
tools are used. A pulling motion, not a pry off
motion, is recommended to remove the caps.

3. Pull gently on the tether strap to confirm that the lever is locked in its stowed position.

Manual Park Release Tether In Stowed Position

4. Reinstall the access cover.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or
snow, it can often be moved using a rocking
motion. Turn the steering wheel right and left to
clear the area around the front wheels. Then shift
back and forth between DRIVE (D) and REVERSE
(R), while gently pressing the accelerator. Use the least amount of accelerator pedal pressure that
will maintain the rocking motion, without spinning
the wheels or racing the engine.
NOTE:
For trucks equipped with an 8–speed transmis
-
sion, shifts between DRIVE and REVERSE can
only be achieved at wheel speeds of 5 mph
(8 km/h) or less. Whenever the transmission
remains in NEUTRAL (N) for more than two
seconds, you must press the brake pedal to
engage DRIVE or REVERSE.
Push the ESC OFF button, to place the Electronic
Stability Control (ESC) system in “Partial Off”
mode, before rocking the vehicle Ú page 271.
Once the vehicle has been freed, push the ESC
OFF button again to restore ESC On mode.
WARNING!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause damage, or even failure, of the axle and
tires. A tire could explode and injure someone.
Do not spin your vehicle's wheels faster than
30 mph (48 km/h) or for longer than 30
seconds continuously without stopping when
you are stuck and do not let anyone near a
spinning wheel, no matter what the speed.
CAUTION!
Racing the engine or spinning the wheels may
lead to transmission overheating and failure.
Allow the engine to idle with the transmission
in NEUTRAL for at least one minute after every
five rocking-motion cycles. This will minimize
overheating and reduce the risk of transmis -
sion failure during prolonged efforts to free a
stuck vehicle.
When “rocking” a stuck vehicle by shifting
between DRIVE and REVERSE, do not spin the
wheels faster than 15 mph (24 km/h), or
drivetrain damage may result.
Revving the engine or spinning the wheels too
fast may lead to transmission overheating and
failure. It can also damage the tires. Do not
spin the wheels above 30 mph (48 km/h)
while in gear (no transmission shifting occur -
ring).
