(3) Air pressure in the tires is controlled by the CTIS ECU (6). The CTIS ECU provides

for five tire pressure settings which are; highway, cross-country, sand, emergency, and

run-flat. Kneeling valves (7) on the front tires allow the front of the vehicle to be lowered

for internal air transport (C-130 and C-141). Air pressure is also used to keep the cab

level through the use of air springs (8), mounted below the rear cab support, and a cab

leveling valve (9).
