If these chemicals contact the skin or eyes, flush immediately with water for a minimum of 15 minutes and get prompt medical attention. If any part of the bat- tery is swallowed, contact a physician immediately. When disposing of TPMS sensors, follow the correct procedures for hazard- ous material disposal. Failure to follow these instructions may result in serious personal injury. NOTE: e TPMS sensor cannot be removed without disassembly of the wheel and tire. Removal NOTE: Failure to follow the instruc- tions below may result in damage to the TPMS sensor. 1) Remove the wheel and tire. NOTE: e valve stem is connected to the TPMS sensor. Do not pull the valve stem from the wheel, or damage to the sensor will occur. 2) Remove the valve stem core and fully deflate all air from the tire. 3) Remove the tire from the wheel fol- lowing the tire manufacturer's directions. 4) Remove the TPMS sensor from the valve in the following sequence (see Figure 1). 1) Using a T10 Torx, remove the valve stem-to-TPMS sensor screw. 2) Carefully and firmly, pull the sensor straight down and separate it from the valve stem. NOTE: A new valve stem must be installed whenever a new tire or wheel is installed. NOTE: When installing a new wheel, always install a new valve stem and reuse the TPMS sensor from the previous wheel if possible. e TPMS will not have to be trained if the sensor is reused. 5) Using a suitable valve stem puller and a wood block, remove the valve stem from the wheel. 6) If the TPMS sensor is being reused, inspect the TPMS sensor for damage and install new parts as necessary. Installation NOTE: To prevent TPMS sensor and valve stem damage, the valve stem must be installed onto the TPMS sensor and then installed into the wheel as an assembly. 1) Install a new valve stem onto the TPMS sensor tightening the valve stem-to- TPMS sensor screw to13 in.-lbs. (1.5 Nm). NOTE: It is important to pull the valve stem and TPMS sensor assembly through the wheel rim hole in a direction parallel to the valve stem hole axis. If the assembly is pulled through at an angle, damage to the valve stem and sensor assembly may occur. NOTE: Use only a soap and water solu- tion to lubricate the tire. Use of anything other than soap and water may result in damage to the TPMS sensor. 2) Lubricate the valve stem with soapy water and install the valve stem and TPMS sensor assembly into the wheel using a block of wood and a suitable valve stem installer. NOTE: Do not mount the tire at this time. 3) Make sure the valve stem rubber is fully seated against the wheel. 4) Position the wheel on the turntable of the tire machine, then lubricate and position the bottom bead of the tire on the wheel. 5) Mount the tire according to the tire manufacturer's instructions being certain to position the machine arm at 6 o'clock with respect to the location of the valve to avoid damage to the sensor (see Figure 2). 6) Inflate the tire to the pressure specified on the Vehicle Certification (VC) label located on the driver door or door pillar. 7) Install the wheel and tire. 8) If a new sensor has been installed it must be activated (see "Tire pressure sensor activation" and trained (see "Tire pressure sensor training"). ■ Information for this column comes from the tire pressure monitoring systems data in ProDemand®, Mitchell 1's auto repair information software for domestic and import vehicles.
