216 STARTING AND OPERATING CAUTION! The TPM system is designed to monitor your tire pressure and will not function as a tire pressure gauge. After adjusting the air pressure in a tire, there will be a delay before the system updates the display. The system will automatically update and the Tire Pressure Monitoring Indicator Light will turn off, once the system receives the updated tire pressures. The vehicle needs to be driven above 20 mph in order for the TPMS to receive this information. The TPMS will cause the indicator light in the instrument cluster to illuminate whenever the pressure in one tire falls 25% below the recommended pressure shown on the vehicle's tire label. The TPMS will cause the indicator light to flash for approximately one minute and then remain continuously illuminated whenever the system detects a TPMS malfunction. NOTE: The pressure in your tires changes with temperature. A significant decrease in temperature could reduce cold inflation pressure below the TPMS set-point. For example, tires inflated to the proper cold inflation pressure on a warm day or in a warm garage could illuminate the TPMS indicator light on the following day
