Ram 1500/2500/3500: Premium System - If Equipped

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 Electronic Vehicle Information Center (EVIC), and
• 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.

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 will display a "LOW TIRE PRESSURE" message for a minimum of five seconds and a graphic showing the pressure values of each tire with the low tire pressure values flashing or in a different color. An Inflate to XX message will also be displayed.

"LOW TIRE PRESSURE" Message

Should this occur, you should stop as soon as possible and inflate the tires with a low pressure condition (those flashing or in a different color in the EVIC 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 will stop flashing or 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 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 EVIC 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.

Tire Pressure Monitor Display

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 will display a "LOW TIRE PRESSURE" message and a graphic showing the low tire pressure value flashing or 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 stop flashing or 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.
