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 instru -
ment cluster graphic) to the vehicle’s recom-
mended cold placard pressure inflation value
as shown in the "Inflate to XX" message. Once
the system receives the updated tire pressures,
the system will automatically update, the
graphic display in the instrument cluster will
return to its original color, and the “Tire Pres -
sure Monitoring Warning 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.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(28 kPa) above the recommended cold placard
pressure in order to turn the Tire Pressure Moni -
toring Warning Light off.Service TPMS Warning
If a system fault is detected, the “Tire Pressure
Monitoring Warning Light” will flash on and off
for 75 seconds and then remain on solid. 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 Pres -
sure Monitoring Warning 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 materials 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 MonitoringWarning
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 Monitoring Indi -
cator Light” will no longer flash and the tire pres -
sure display screen will be displayed showing
the tire pressure values in the correct locations.

140SAFETY
Tire Pressure Information System (TPIS)
3500/4500/5500 Series Trucks
Your vehicle may be equipped with a Tire Pres -
sure 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 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) 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. 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 materials 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.

390SERVICING AND MAINTENANCE
(Continued)
Dark Vapor Chrome, Black Satin Chrome, or
Low Gloss Clear Coat Wheels
Tire Chains and Traction Devices
Use of traction devices require sufficient
tire-to-body clearance. Due to limited clearance,
the following traction devices are recom-
mended. Follow these recommendations to
guard against damage.
Traction device must be of proper size for the
tire, as recommended by the traction device
manufacturer.
No other tire sizes are recommended for use
with a tire chain or traction device. Chassis Cab 3500 (Single Rear Wheel) Models
Install on rear tires only.
For LT275/70R18E tire, use of a U-class
snow chain is recommended.
Chassis Cab 3500 4x2 (Dual Rear Wheel)
Models
Install on rear tires only.
For a LT235/80R17E tire, use of a U-class
snow chain is recommended.
Chassis Cab 3500 4x4 (Dual Rear Wheel)
Models
Install on front/rear tires.
For a LT235/80R17E tire, use of a U-class
snow chain is recommended.
Chassis Cab 4500/5500 Models
Install on rear tires only.
For a 225/70R19.5G tire, use of a U-class
snow chain is recommended.
CAUTION!
If your vehicle is equipped with these
specialty wheels, DO NOT USE wheel
cleaners, abrasives, or polishing compounds.
They will permanently damage this finish and
such damage is not covered by the New
Vehicle Limited Warranty. HAND WASH ONLY
USING MILD SOAP AND WATER WITH A SOFT
CLOTH. Used on a regular basis; this is all that
is required to maintain this finish.
WARNING!
Using tires of different size and type (M+S,
Snow) between front and rear axles can
cause unpredictable handling. You could lose
control and have a collision.
CAUTION!
To avoid damage to your vehicle or tires,
observe the following precautions:
Because of restricted traction device clear -
ance between tires and other suspension
components, it is important that only trac-
tion devices in good condition are used.
Broken devices can cause serious damage.
Stop the vehicle immediately if noise
occurs that could indicate device breakage.
Remove the damaged parts of the device
before further use.
Install device as tightly as possible and
then retighten after driving about 0.5 mile
(0.8 km). Autosock devices do not require
retightening.
Do not exceed 30 mph (48 km/h).
Drive cautiously and avoid severe turns and
large bumps, especially with a loaded
vehicle.
Do not drive for a prolonged period on dry
pavement.
