UNDERSTANDING YOUR INSTRUMENT PANEL 215 CAUTION! The TPMS has been optimized for the original equipment tires and wheels. TPMS pressures and warning have been established for the tire size equipped on your vehicle. Undesirable system operation or sensor damage may result when using replacement equipment that is not of the same size, type, and/or style. Aftermarket wheels can cause sensor damage. Do not use tire sealant from a can, or balance beads if your vehicle is equipped with a TPMS, as damage to the sensors may result. 25. Airbag Indicator The airbag indicator light illuminates and remains lit for six to eight seconds when the ignition is first turned ON. If the light does not come on when the ignition is first turned on, or the light stays on or comes on while driving, have the airbag system checked by an authorized dealer. 26. 4WD Indicator The 4WD indicator light illuminates when the transfer case is in 4WD position. 27. SVC (Service) 4WD Indicator The SVC 4WD light will illuminate when the ignition key is turned to the ON position and will stay on for two seconds. If the light stays on or comes on during driving, it means that the 4WD system is not functioning properly and that service is required. 28.
