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 Tire Pressure Monitor (TPM) system “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 infla-
tion pressures for the vehicle when operating in the Max
Load condition. A Supplemental Tire Pressure Informa-
tion 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 Tire Pressure Monitoring (TPM) system is using
the light load inflation pressure (cold) low inflation
warning thresholds and will warn the driver if one or
more of the tire pressures are 25% or more below the
vehicle’s defined light load inflation pressures.
