Jeep Cherokee (KL): Tire pressure monitor system (tpms)

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 Electronic Vehicle Information Center (EVIC)/Driver information Display (DID) will display a Tire Low message for a minimum of five seconds, an Inflate to XX message and a graphic showing the pressure values of each tire with the low tire pressure values in a different color.

Tire Pressure Monitoring Low Pressure Warning

Should this occur, you should stop as soon as possible and inflate the tires with low pressure (those in a different color in the EVIC/DID graphic) to the vehicle's recommended cold placard pressure value as shown in the Inflate to XX message. Once the system receives the updated tire pressures, the system will automatically update, the pressure values in the graphic display in the EVIC/DID will return to their original color, and the "Tire Pressure Monitoring Telltale Light" will turn off.

NOTE: When filling warm tires, the tire pressure may need to be increased up to an additional 4 psi (30 kPa) above the recommended cold placard pressure in order to turn the Tire Pressure Monitoring Telltale Light off.

The vehicle may need to be driven for up to 20 minutes above 15.5 mph (25 km/h) in order for the TPMS to receive this information.

SERVICE TPMS Warning

When 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/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.

Tire Pressure Monitoring Service Warning

If the ignition key 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. Jamming due to electronic devices or driving next to facilities emitting the same radio frequencies as the TPMS sensors.

2. Installing some form of aftermarket window tinting that affects radio wave signals.

3. Lots of snow or ice around the wheels or wheel housings.

4. Using tire chains on the vehicle.

5. Using wheels/tires not equipped with TPMS sensors.

Vehicles With Matching Full-Size Spare

1. The matching full size spare wheel and tire assembly has a tire pressure monitoring 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, a chime will sound and the "TPMS Telltale Light" will turn on upon the next ignition key cycle. In addition, the EVIC/DID will display a Tire Low message, an Inflate to XX message and a graphic showing the low tire pressure value in a different color.

3. After driving the vehicle for up to 20 minutes above 15.5 mph (25 km/h) the "TPMS Telltale Light" will turn OFF, as long as no tire pressure is below the low-pressure warning limit in any of the four active road tires.

4. The EVIC/DID will display a graphic showing the tire pressure value in the same color as the other pressure values in place of the different color low tire pressure value. The EVIC/DID will also display a "SPARE LOW PRESSURE" message to remind you to service the flat tire.

Vehicles With Compact Spare or Non-Matching Full Size Spare

1. The compact spare tire or non-matching full size does not have a tire pressure monitoring sensor. Therefore, the TPMS will not monitor the pressure in the compact spare tire.

2. If you install the compact or non-matching full size spare tire in place of a road tire that has a pressure below the low-pressure warning limit, upon the next ignition key cycle, the "TPMS Telltale Light" will remain on and a chime will sound. In addition, the graphic in the EVIC/DID will still display a different color pressure value and an Inflate to XX message.

3. After driving the vehicle for up to 20 minutes above 15.5 mph (25 km/h), the "TPMS Telltale Light" will flash on and off for 75 seconds and then remain on solid. In addition, the EVIC/DID will display a "SERVICE TPM SYSTEM" message for five seconds and then display dashes (- -) in place of the pressure value.

4. For each subsequent ignition key cycle, a chime will sound, the "TPMS Telltale Light" will flash on and off for 75 seconds and then remain on solid, and the EVIC/DID will display a "SERVICE TPM SYSTEM" message for five seconds and then display dashes (- -) in place of the pressure value.

5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of the compact spare or non-matching full size, the TPMS will update automatically. In addition, the "TPMS 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. The vehicle may need to be driven for up to 20 minutes above 15.5 mph (25 km/h) in order for the TPMS to receive this information.
