Maintenance and Specifications 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. Speed ranges: • Low 25-42 mph (40-68 km/h) • Medium 42-62 mph (68-100 km/h) • High - above 62 mph (100 km/h) This system may not function properly under the following conditions: • Uneven tread wear. • Driving on loose or low traction surfaces such as gravel, snow or slush. • Using tire chains • Initial tire pressures out of specified range. 250 2004 Monterey (mty) Owners Guide (post-2002-fmt) USA English (fus)
