STARTING AND OPERATING 341 Tire Pressure Monitor System (TPMS) "Light Load" Reset Switch Description - If Equipped WARNING! Never operate your vehicle with the TPMS and tire pressures set to the Light Load Inflation Pressure settings if carrying more than two occupants (150 lbs each) plus 200 pounds of cargo. The vehicle "Light Load Definition" is found in the Supplemental Tire Pressure Information Label which is located on the rear face of the driver door. Failure to do so may cause you to lose control resulting in an accident, causing serious or fatal injury. The TPMS "Light Load" reset switch will allow the driver to switch between the max load inflation pressure (cold) low pressure warning threshold and the light load inflation pressure (cold) low pressure warning threshold depending on the vehicle's load condition. The Tire and Loading Information label defines the recommended front and rear cold tire inflation pressures for the vehicle when operating in the Max Load condition. A Supplemental Tire Pressure Information label is also available defining Light Load tire inflation pressures when operating in the Light Load condition. When the "Light Load" reset switch LED is ON, the TPMS is using the light load inflation pressure (cold) low inflation warning thresholds. 5
