90 UNDERSTANDING YOUR INSTRUMENT PANEL 2. Low Tire Pressure Indicator Light The tire pressure monitor (TPM) system uses wireless technology to monitor tire pressure levels. Sensors, mounted to each wheel as part of the valve stem, transmit tire pressure readings to a receiver located in the vehicle. If the light is illuminated, the pressure in one of the tires on the vehicle has dropped to at least 25% below the recommended pressure on the vehicle's tire label. Additionally, the indicator light will illuminate if a fault has been detected in the TPM system. NOTE: The TPM system can inform you about a low tire pressure condition, but it does not replace normal tire maintenance. The TPM system is not intended to provide you with notification of rapid pressure loss. NOTE: The pressure in your tires changes with temperature. A significant decrease in temperature could reduce cold inflation pressure below the TPM setpoint. ALWAYS check the pressure in your tires if the TPM lamp is illuminated. 3. Coolant Indicator Light This indicator illuminates when the engine coolant has dropped below the required level in the reservoir or the coolant temperature is too high (see the Temperature gauge section). To check the coolant level, the vehicle must be parked on level ground and the engine stopped. Check coolant level only when the coolant is cold. 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.
