Wheels and Tires: Description and Operation
DESCRIPTION AND OPERATIONWheels And Tires
WARNING: Do not mix different types of tires, such as radial, bias or bias-belted on the same vehicle except in emergencies. Vehicle handling can be seriously affected and can result in loss of control.
Factory-installed tires and wheels are designed to operate satisfactorily with loads up to and including full-rated load capacity when inflated to recommended inflation pressures.
Low Tire Warning (LTW) System
The Low Tire Warning (LTW) system detects differences in inflation pressures in one or more tires. The system uses the ABS wheel speed sensors to monitor the rolling radius of the wheel and tire assemblies. If a difference in rolling radius is detected, the ABS module illuminates the LTW lamp located in the instrument cluster.
Low Tire Warning (LTW) System Resetting
The LTW system must be reset when tire replacement, maintenance, system repair is carried out or any time tire pressure is adjusted.
Vehicles Without Message Center
To reset the system, press and hold the odometer reset button and wait for the TIRE PRESSURE SET light to illuminate. Continue to press the button for 3 seconds, then release. After 3 seconds, the low tire pressure warning lamp will flash 3 times, indicating that the low tire warning system reset procedure is complete.
Vehicles With Message Center
To reset the system, press and hold the SETUP button and wait for the message center to display REST FOR SYSTEM CHECK. Then press the RESET button and wait for the message center to display HOLD RESET TO RELEARN . Press and hold the RESET button for 3 seconds. The message HOLD RESET TO RELEARN and the low tire warning lamp will flash 3 times, indicating the reset procedure is complete.
If the lamp illuminates, reset the tire pressure to specification before resetting the system. If the problem persists GO to Symptom Chart.
The LTW system is not capable of detecting rapid loss of inflation. The system may not detect loss of inflation in more than one tire.
The LTW system can be deactivated.
