CHECK TIRE PRESSURE This symbol appears with the CHECK TIRE PRESSURE message. CHECK WASHER FLUID This symbol appears with the CHECK WASHER FLUID message. If your vehicle has a Tire Pressure Monitor (TPM) system, this message will display when one or more of the vehicle's tires are low or high. See DIC Controls and Displays on page 3-74 for information on checking your vehicle's tire pressures. When this message displays, it means that your vehicle is low on windshield washer fluid. You should refill the tank as soon as possible. See Windshield Washer Fluid on page 5-41 for more information. CLEAN RADAR When this message displays, it means that the Adaptive Cruise Control system is disabled because the radar is blocked and cannot detect vehicles in your path. It may also activate during heavy rain or due to road spray. To clean the system, see "Cleaning the System" under Adaptive Cruise Control on page 3-19. 3-82
