Tires, Wheels and Loading is located underneath the truck, by the forward stake pocket on the left side of the bed. If operating the air system in dusty areas, periodically inspect this filter and replace it if found to be clogged or damaged, or if the time needed to pressurize the system starts to become extended. Using the air system to fill tires To fill your tires, first be sure to stop the truck in a safe place. You should be far enough off the road that passing traffic will not be a danger to you. You should have an accurate tire pressure gauge to measure the pressure in the tires and inflate them to the settings on the tire pressure placard, which is usually inside the door on the truck. Remove the air hose from under the clamp on the floor of the truck. Attach the connector end of the hose to the coupling in the trim panel behind the driver's seat by using one hand to slide the coupling collar toward the trim panel and the other to insert the fitting on the end of the hose into the coupling. When the fitting is seated in the coupling, slide the collar back to its original position. Extend the hose to reach the tire needing air. Remove the cap from the tire valve stem and attach the clamp-on air chuck by squeezing the locking mechanism while placing the chuck over the valve stem. Release the locking mechanism when the air chuck is seated on the stem. Air will flow from the system to the tire until you remove the chuck. Be sure to use your gauge to set the pressure according to the placard. When the tire pressure is correct, disconnect the hose and re-stow it under the clamp on the floor behind the passenger seat. Do not forget to re-install the cap on the valve stem. CENTRAL TIRE INFLATION SYSTEM (CTIS) (IF EQUIPPED) Your vehicle may be equipped with a Central Tire Inflation System (CTIS). The CTIS adjusts and maintains tire pressure for enhanced vehicle traction, reduced vehicle maintenance and improved driver comfort. The system is operated through instrument panel-mounted controls. Operating the CTIS The CTIS is operated and observed through the Driver Display Module (DDM) and the LOAD AND TERRAIN controls. 23
