cate the transmission. Do not exceed 10 mph (16 km/hr). If the engine cannot be run, release
the parking brake by following the manual parking brake release procedure on page 3-21. Do
not exceed 3 mph (5 km/hr) and one mile (1.6 km) total distance while towing. It is recom-
mended by the axle and transmission manufacturer to remove both drive shafts, prior to tow-
ing. Afterward, reset the park brake by the procedure on page 3-21.
