Dodge 2009 Ram 1500 - Manual (Page 371)

Tire Pressure Monitor System (TPMS) Tire Light
Load Inflation 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
[68 kg] each) plus 200 pounds (91 kg) 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 tire light load inflation 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 tire light load inflation switch
LED is ON, the TPMS is using the light load inflation
pressure (cold) low inflation warning thresholds.
