NOTE:If your vehicle is equipped with a Tire Pressure
Information System (TPIS):
•The Tire Pressure Information System (TPIS) uses
unique sensors in the inner rear wheels to help identify
them from the outer rear wheels, because of this, the
inner and outer wheel locations can’t be switched.
•After a tire rotation is completed, as shown below, the
system can auto learn the locations of each sensor ID.
Auto learning/localization occurs when the vehicle
ignition status is changed from Off to On and speeds of
greater than 5 mph (8km/h) are obtained and remain
over 5 mph (8km/h) for at about a 15 minute period.
You may need to drive for 20 minutes to account
slower speeds and stops.
•If the tires are rotated incorrectly, The Auto localization
of the TPIS sensors will fail to locate correctly resulting
in incorrect locations for the pressure values displayed
in the Instrument Cluster.
CAUTION!
3500 Dual Rear Tires may only have one approved
direction of rotation. This is to accommodate the
asymmetrical design (tread pattern) of the On/Off-
Road tire and the use of Outline White Letter (OWL)
tires.

CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to your local dealer to have your
sensor function checked.
•After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the TPM sensor.
NOTE:
•The TPMS is not intended to replace normal tire care
and maintenance or to provide warning of a tire failure
or condition.
•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 mainte-
nance, 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 illumination of the “Tire Pressure Monitor-
ing Telltale Light.”
628 STARTING AND OPERATING

•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Premium System
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.
The TPMS consists of the following components:
•Receiver module
•Four TPM sensors
•Various TPMS messages, which display in the Elec-
tronic Vehicle Information Center (EVIC)/Driver In-
formation Display (DID)
•TPM Telltale Light
The matching full size spare wheel and tire assembly (if
equipped) has a TPM sensor. The full size spare can be
used in place of any of the four road tires. A spare with a
pressure below the low-pressure limit will not cause the
“Tire Pressure Monitoring Telltale Light” to illuminate or
the chime to sound while it is stored in the spare tire
location.
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 EVIC/DID will
display a “LOW TIRE” message and a graphic showing
5
STARTING AND OPERATING 629

Page 632 of 871

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.
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 EVIC/DID 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 automatically update, the graphic display in the
EVIC/DID will return to it’s original color, and the “Tire
Pressure Monitoring 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.
Service TPMS Warning
If a system fault is detected, the “Tire Pressure Monitor-
ing 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 EVIC/DID will display a#SER-
VICE 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.
“LOW TIRE PRESSURE” Message
630 STARTING AND OPERATING

Page 633 of 871

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:
1. Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors.
2. Installing aftermarket window tinting that contains
materials that may block radio wave signals.
3. Accumulation of snow or ice around the wheels or
wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.

Vehicles With Full Size Spare
1. The matching full size spare wheel and tire assembly
has a TPM sensor that can be monitored by the TPMS.
2. If you install the full size spare in place of a road tire
that has a pressure below the low-pressure warning
limit, upon the next ignition switch cycle, a chime will
sound and the “Tire Pressure Monitoring Telltale
Light” will turn ON. In addition, the EVIC/DID will
display a “LOW TIRE” message and a graphic show-
ing the low tire pressure value in a different color. An
#Inflate to XX#message will also be displayed.
3. After driving the vehicle for up to 20 minutes above
15 mph (25 km/h) the “Tire Pressure Monitoring
Telltale Light” will turn OFF and the pressure value
will be updated and return to it’s original color, as
long as no tire pressure is below the low-pressure
warning limit in any of the four active road tires.
Tire Pressure Information System (TPIS) 3500
Series Trucks
Your vehicle may be equipped with a Tire Pressure
Information System (TPIS).
The Tire Pressure Information System (TPIS) uses wire-
less technology with wheel rim mounted electronic sen-
sors 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) applica-
tions)
632 STARTING AND OPERATING

Page 635 of 871

•Six TPM sensors (Dual Rear Wheel (DRW) applica-
tions)
•Pressure display in the Electronic Vehicle Information
Center (EVIC)/Driver Information Display (DID)
The TPIS system will display all four (Single Rear Wheel
(SRW) applications) or six (Dual Rear Wheel (DRW)
applications) tire pressure values in the EVIC/DID dis-
play.
If a system fault is detected, the EVIC/DID 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.
