For increased fuel economy in 2WD, rotate both hub locks to the FREE position. • For proper operation, make sure that each hub is fully engaged and that both hub locks are set to the same position (both set to LOCK or both set to FREE). To engage LOCK, turn the hub locks completely clockwise; to disengage the hubs (FREE), turn the hub locks completely counterclockwise. • Some vehicles may be equipped with wheel ornaments that cover the 4x4 manual hub lock. These ornaments must be removed to access the manual hub locks.
