SAFETY 179
NOTE:
• The  TPMS is not  intended  to replace  normal tire  care and
maintenance  or  to  provide  warning  of  a  tire  failure  or
condition.
• If  your  vehicle  is  not  equipped  with  the  Tire  Fill  Alert
feature  the  TPMS  should  not  be  used  as  a  tire  pressure
gauge while adjusting your tire pressure.
• Driving  on  a  significantly  under-inflated  tire  causes  the
tire to overheat and can lead to tire failure. Under-inflation
also  reduces  fuel  efficiency  and  tire  tread  life,  and  may
affect the vehicle’s handling and stopping ability.
• The  TPMS is  not a substitute  for proper  tire maintenance,
and it is the driver’s responsibility to maintain correct tire
pressure  using  an  accurate  tire  pressure  gauge,  even  if
under-inflation has not reached the level to trigger illumi -
nation of the TPMS Warning Light.
• Seasonal temperature changes will affect tire pressure, and
the TPMS will monitor the actual tire pressure in the tire. Example: Tire Pressure Monitor Display
The  Tire  Pressure  Monitor  System  (TPMS)  uses  wireless
technology  with  wheel  rim  mounted  electronic  sensors  to
monitor 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. 4

180 SAFETY
The TPMS consists of the following components:
• Receiver module
• Four tire pressure monitoring sensors
• Various tire pressure monitoring system messages, which
display in the instrument cluster
• Tire Pressure Monitoring System Warning Light
Tire Pressure Monitoring Low Pressure Warnings
The  “Tire  Pressure  Monitoring  Telltale  Light”  will
illuminate in the instrument cluster and a chime will
sound when tire pressure is low in one or more of the
four active road tires. In addition, the instrument cluster will
display  a  graphic  showing  the  pressure  values  of  each  tire
with  the  low  tire  pressure  values  in  a  different  color.  An
"Inflate to XX" message will also be displayed. Example: Low Tire Pressure Display
Should  this  occur,  you  should  stop  as  soon  as  possible  and
inflate  the  tires  with  a  low  pressure  condition  (those  in  a
different  color  in  the  instrument  cluster  graphic)  to  the
vehicle’s recommended cold placard pressure inflation value
as  shown  in  the  "Inflate  to  XX"  message.  Once  the  system
receives the updated tire pressures, the system will automat -
ically  update,  the  graphic  display  in  the  instrument  cluster
will return to it’s original color, and the “Tire Pressure Moni -
toring  Telltale Light” will turn off. The  vehicle may need to
be  driven  for  up  to  20 minutes  above  15 mph  (24 km/h)  in
order for the TPMS to receive this information.

SAFETY 181
NOTE:
When  filling  warm  tires,  the  tire  pressure  may  need  to  be
increased up to an additional 4 psi (28 kPa) above the recom -
mended cold placard pressure in order to turn the Tire Pres -
sure Monitoring Telltale Light off.
Service TPMS Warning
If  a  system  fault  is  detected,  the  “Tire  Pressure  Monitoring
Telltale Light” will flash on  and  off for 75 seconds and then
remain on solid. The system fault will also sound a chime. In
addition,  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 indi -
cate 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  “Tire  Pressure  Monitoring  Telltale  Light”
will  no  longer  flash,  and  the  "SERVICE  TPM  SYSTEM"
message  will  no  longer  display,  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 mate -
rials 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.
A  system  fault  may  occur  due  to  an  incorrect  TPM  sensor
location  condition.  When  a  system  fault  occurs  due  to  an
incorrect TPM sensor location, the “Tire Pressure Monitoring
Telltale Light” will flash on  and off for 75 seconds and then
remain on solid. The system fault will also sound a chime. In
addition, the instrument cluster will display a “Tire Pressure
Temporarily Unavailable” message in place  of the tire  pres -
sure  display  screen.  If  the  ignition  switch  is  cycled,  this
sequence will repeat, providing the system fault still exists. If
the  system  fault  no  longer  exists,  the  “Tire  Pressure  Moni -
toring  Telltale  Light”  will  no  longer  flash  and  the  tire  pres -
sure  display  screen  will  be  displayed  showing  the  tire
pressure values the correct locations. 4

182 SAFETY
Vehicles With Non  Matching Full Size Spare Or Compact
Spare
• The  non  matching  full  size  spare  or  compact  spare  tire
does not have a TPM sensor. Therefore, the TPMS will not
monitor the pressure in the non matching full size spare or
compact spare tire.
• If  you  install  the  non  matching  full  size  spare  or  compact
spare tire in place of a road tire that has a pressure below the
low-pressure  warning  limit,  upon  the  next  ignition  switch
cycle,  the  TPM  Telltale  Light  and  a  “LOW  TIRE”  message
will  remain  ON  and  a  chime  will  sound.  In  addition,  the
graphic in the instrument cluster will still display a pressure
value in a different color and an “Inflate to XX” message.
• After  driving  the  vehicle  for  up  to  20 minutes  above
15 mph  (24 km/h),  the  TPM  Telltale  Light  will  flash  on
and  off  for  75  seconds  and  then  remain  on  solid.  In  addi -
tion, 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.
• For  each  subsequent  ignition  switch  cycle,  a  chime  will
sound,  the  TPM  Telltale  Light  will  flash  on  and  off  for  75
seconds  and  then  remain  on  solid,  and  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. • Once you repair or replace the original road tire and rein -
stall it on the vehicle in place of the non matching full size
spare  or  compact  spare,  the  TPMS  will  update  automati -
cally. In addition, the TPM Telltale Light will turn OFF and
the  graphic  in  the  instrument  cluster  will  display  a  new
pressure  value  instead  of  dashes  (-  -),  as  long  as  no  tire
pressure is below the low-pressure warning limit in any of
the  four  active  road  tires.  The  vehicle  may  need  to  be
driven  for  up  to  20 minutes  above  15 mph  (24 km/h)  in
order for the TPMS to receive this information.
Trailer Tire Pressure Monitoring System (TTPMS)
The  Trailer  Tire  Pressure  Monitoring  System  (TTPMS)  is  a
feature  that  will  display  the  trailer  tire  pressure  values  and
warn  the  driver  of  a  low  trailer  tire  pressure,  based  on  the
drivers set target tire pressure value, through the Instrument
Cluster (IC).
The TTPMS monitors the pressure of each tire and warns the
driver, through the IC, when either a low tire pressure condi -
tion or a TPM sensor or system malfunction condition exists.
The IC will display the actual tire pressure or dashes for each
of  the  trailer  tires  in  the  correct  trailer  position,  based  on
trailer configuration. 
Page 185 of 607

SAFETY 183
The TTPMS consist of the following components:
• Trailer Receiver Module
• Trailer Interface Module
• Two to twelve tire pressure monitoring sensors depending
on trailer configuration
The TTPMS is configured though the trailer settings menu in the
Uconnect system by selecting the desired trailer number (up to
four trailers can be configured), the number of axles (1 - 3), the
number  of  trailer  tires  (2,  4,  6,  8,  or  12),  and  the  set  trailer  tire
pressure.  Refer  to  “Uconnect  Settings”  in  “Multimedia”  for
further information.
Tire Pressure Monitoring Low Pressure Warnings
When  a  tire  pressure  low  in  one  or  more  of  the  active  road
tires  is  detected  a chime  will  sound.  In  addition,  the  instru -
ment  cluster  will  display  a  graphic  showing  the  pressure
values  of  each  tire  with  the  low  tire  pressure  values  in  a
different  color.  An  “Inflate  to  XXX”  message  will  also  be
displayed.
NOTE:
"XXX" = TPM trailer tire target pressure value programmed
by the customer Should  this  occur,  you  should  stop  as  soon  as  possible  and
inflate  the  tires  with  a  low  pressure  condition  (those  in  a
different  color  in  the  instrument  cluster  graphic)  to  the
customer programmed target tire pressure value as shown in
the  “Inflate  to  XXX”  message.  Once  the  system  receives  the
updated tire pressures, the system will automatically update
the  graphic  display  in  the  instrument  cluster  will  return  to
it’s original color. The vehicle may need to be driven  for up
to  10 minutes  above  15 mph  (24 km/h)  in  order  for  the
TTPMS to receive the updated information.
Service TTPMS Warning
If  a  system  fault  is  detected,  the  system  fault  will  sound  a
chime and the instrument cluster will display a “Trailer Tire
Pressure System Service Required” 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.
Once  the system  fault is corrected the  "Trailer  Tire  Pressure
System  Service  Required"  message  will  no  longer  be
displayed  and  the  dashes  will  be  replaced  by  pressure
values.  The  vehicle  may  need  to  be  driven  for  up  to
10 minutes above 15 mph (24 km/h) in order for the TTPMS
to receive the updated information. 4

184 SAFETY
Trailer Tire Pressure System Not Configured
A  “Trailer  Tire  Pressure  System  Not  Configured”  message
will  be  displayed  in  the  Instrument  Cluster  when  a  trailer
number  is  selected  that  does  not  have  configuration  values
entered  for  the  (Number  of  Tires,  Number  of  Axles,  SET
Target Tire Pressure, trailer TPM sensor ID's).
To  correct  this  condition  the  (Number  of  Tires,  Number  of
Axles, and SET Target Tire Pressure) values must be entered
in  the  radio  for  the  trailer  number  selected.  The  trailer
sensors must also be paired to the trailer. Refer to the “Ucon -
nect Settings” in “Multimedia” for further information.
Trailer Sensors Detected Do Not Match Active Trailer
The “Trailer Sensors Detected Do Not Match Active Trailer”
message  will  be  displayed  in  the  Instrument  Cluster  when
the  trailer  sensors  being  received  by  the  TTPM  module  do
match the trailer sensors paired to the current trailer number
selected.  This  message  will  be  displayed  when  the  sensors
being  received  completely  match  the  sensors  paired  to
another trailer number configured in the TTPM module.
To correct this condition, the correct trailer number must be
selected  in  the  radio.  Refer  to  the  “Uconnect  Settings”  in
“Multimedia” for further information. Tire Fill Alert
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:
• 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
TPM  system  fault  is  set  to  “active”  or  if  the  system  is  in
deactivation mode (if equipped).
The system will be activated when the TPM 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. 
Page 187 of 607

SAFETY 185
When  Tire  Fill  Alert  Mode  is  entered,  the  tire  pressure
display screen will be displayed in the instrument cluster.
Operation:
• The  horn  will  chirp  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
under-inflated  and  will  continue  to  chirp  every  five
seconds if the user continues to deflate the tire.
Selectable Tire Fill Alert (STFA)
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 customer settings menu in the
radio,  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  incre -
ments  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.
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 system will be activated when the TPM 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.
When  Tire  Fill  Alert  Mode  is  entered,  the  tire  pressure
display screen will be displayed in the instrument cluster. 4

186 SAFETY
Operation:
• The  horn  will  chirp  once  when  the  selected  pressure  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 Series 
Trucks
Your vehicle may be equipped with a Tire Pressure Informa -
tion 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 TPM sensors (Single Rear Wheel (SRW) applications)
• Six TPM sensors (Dual Rear Wheel (DRW) applications)
• Pressure display in the instrument cluster
The  TPIS  system  will  display  all  four  (Single  Rear  Wheel
(SRW) applications) or six (Dual Rear Wheel (DRW) applica -
tions) 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.  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. 
Page 189 of 607

SAFETY 187
• Installing aftermarket window tinting that contains mate -
rials that may block radio wave signals.
• Accumulation of snow or  ice around the wheels or wheel
housings.
• Using tire chains on the vehicle.

188 SAFETY
(Continued)Important Safety Precautions
Please  pay close  attention  to  the information in this  section.
It  tells  you  how  to  use  your  restraint  system  properly,  to
keep you and your passengers as safe as possible.
Here are some simple steps you can take to minimize the risk
of harm from a deploying air bag:
1. Children  12  years  old  and  under  should  always  ride
buckled up in the rear seat of a vehicle with a rear seat.
2. A child who is not big enough to wear the vehicle seat belt
properly  (Refer  to  “Child  Restraints”  in  this  section  for
further  information)  must  be  secured  in  the  appropriate
child  restraint  or  belt-positioning  booster  seat  in  a  rear
seating position.
3. If a child from 2 to 12 years old (not in a rear-facing child
restraint) must ride in the front passenger seat, move the
seat  as  far  back  as  possible  and  use  the  proper  child
restraint  (Refer  to  “Child  Restraints”  in  this  section  for
further information).
4. Never  allow  children  to  slide  the  shoulder  belt  behind
them or under their arm. 5. You  should  read  the  instructions  provided  with  your
child restraint to make sure that you are using it properly.
6. All occupants should always wear their lap and shoulder
belts properly.
7. The  driver  and  front  passenger  seats  should  be  moved
back as far as practical to allow the front air bags room to
inflate.
8. Do  not  lean  against  the  door  or  window.  If  your  vehicle
has  side  air  bags,  and  deployment  occurs,  the  side  air
bags  will  inflate  forcefully  into  the  space  between  occu -
pants and the door and occupants could be injured.
9. If the air bag system in this vehicle needs to be modified
to  accommodate  a  disabled  person,  refer  to  the
“Customer  Assistance”  section  for  customer  service
contact information.
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.
