316 STARTING AND OPERATING CAUTION! The TPMS has been optimized for the original equipment tires and wheels. TPMS pressures 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 aftermarket sealants or balance beads if your vehicle is equipped with a TPMS, as damage to the sensors may result. CAUTION! After inspecting or adjusting the tire pressure, always reinstall the valve stem cap. This will prevent moisture and dirt from entering the valve stem, which could damage the TPMS sensor. NOTE: • The TPMS is not intended to replace normal tire care and maintenance, or to provide warning of a tire failure or condition. • The TPMS should not be used as a tire pressure gauge while adjusting your tire pressure. • Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure.Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability.
