Tires, Wheels and Loading When a tire loses inflation, the low tire warning system detects the change and illuminates the low tire warning indicator light as shown. If the light remains on while driving, check the tire pressure refer to "Checking the tire pressure" in this chapter. The low tire warning indicator light will also illuminate when using a temporary spare, refer to "Changing the tires" in the Roadside emergencies chapter. The low tire warning system may not detect an under-inflated tire under all conditions and is not a substitute for manually checking tires regularly for proper inflation. When to RESET the Low Tire Warning System: after any of the following • Tire rotation • One or more tires have been replaced • Tire balancing • Wheel alignment • Adjusting the pressure on one or more tires (note: tire pressures are often adjusted during oil change service) • Inflating a low tire will not clear the Low Tire Warning indicator light. Only resetting the system will clear the light. • The system will not detect a pressure loss without driving the vehicle for at least 0.5 mile (0.8 km) at speeds greater than 25 mph (40 km/h). To reset turn the ignition to the ON position, press the set up button on the message center until "SYSTEM CHECK" is displayed. Press the RESET button until "HOLD RESET TO LEARN" is displayed, continue to hold the button for three seconds. The low tire warning indicator light will flash three times as the low tire warning system begins to initialize. The system normally requires 15 to 20 minutes of driving in each of three speed ranges to learn how the tires behave after the system has been reset. However, the system will become functional in each speed range as soon as learning completes in each individual speed range. 192 2005 Monterey (mty) Owners Guide (post-2002-fmt) USA_English (fus)
