drive axle on the vehicle.
Refer to TPMS Troubleshooting Guide in Appendix

CHANGING WHEEL

In case of a flat tire, turn ON the hazard flashers and
bring the vehicle to a stop on the side of the road.
Apply the parking brake. Make sure the vehicle is
parked safely away from traffic. Set up the triangular
reflectors in accordance with applicable highway
regulations.
We suggest that you do not attempt to change a
wheel. First, the wheel and tire are very heavy and
usually there is no space available to put the
removed flat. Second, the wheel nuts, especially
those on inner dual, can become very tight after
being on for only a short time. Often a heavy air
wrench is required to get these nuts loose. We
suggest you get help via CB radio or cellular phone.
There are tire service trucks all over the country that
can bring a wheel and make the change safely.

EMERGENCY AIR-FILL VALVES

The vehicle is equipped with two air system
emergency fill valves to supplement the air system
when air pressure is low and the engine cannot be
operated. One valve is located inside the front
service compartment. The other valve is located
inside the engine compartment.
Both air system emergency fill valves are fitted with
standard tire valve stems. The air systems can be
filled using any standard external air supply line. The
fill valve located in the engine compartment supplies
air for all systems (brakes, suspension and
accessories). The fill valve located in the front
service compartment supplies air for accessories
only.
Air filled through the two emergency fill valves will
pass through the standard air filtering- drying
system. Do not fill air at any other location. Do not
exceed 120 psi (827 kPa).
