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 theSERVICE TPMSYSTEMmessage 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.
Tire Pressure Monitor Display
670 STARTING AND OPERATING
Page 673 of 916

Vehicles With Matching Full Size Spare
•The matching full size spare wheel and tire assembly
has a TPM sensor that can be monitored by the TPMS.
•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 XXmessage will also be displayed.
•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.Vehicles With Non Matching Full Size Spare Or Com-
pact 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
EVIC/DID will still display a flashing pressure value
or a pressure value in a different color.
•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
addition, the EVIC/DID will display aSERVICE TPM

STARTING AND OPERATING 671

SYSTEMmessage 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 EVIC/
DID will display aSERVICE TPM SYSTEMmessage
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
reinstall it on the vehicle in place of the non matching
full size spare or compact spare, the TPMS will update
automatically. In addition, the TPM Telltale Light will
turn OFF and the graphic in the EVIC/DID 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. Thevehicle 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.
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.
672 STARTING AND OPERATING
Page 675 of 916

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) 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 SYSTEMmessage 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, theSERVICE TPM SYSTEMmessage
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.

Air Conditioning
Turn off temporarily.
Air Suspension System
To aid in attaching/detaching the trailer from the vehicle,
the air suspension system can be used. Refer to “Air
Suspension System” in “Starting And Operating” for
further information.
NOTE:The vehicle must remain in the engine running
position while attaching a trailer for proper leveling of
the air suspension system.
SNOWPLOW
1500 Models Only
NOTE:Do not use this model vehicle for snowplow
applications.
WARNING!
Snowplows and other aftermarket equipment should
not be added to the front end of your vehicle. The
airbag crash sensors may be affected by the change in
the front end structure. The airbags could deploy
unexpectedly or could fail to deploy during a colli-
sion resulting in serious injury or death.
CAUTION!
Using this vehicle for snowplow applications can
cause damage to the vehicle.
WARNING!
Attaching a snowplow to this vehicle could adversely
affect performance of the airbag system in a collision.
