Driving Using a Manual Shift On Stop (MSOS) 4x4 system (if equipped) Note: High shift efforts may be encountered when attempting to shift into and out of 4x4 modes. It is recommended to allow the vehicle to roll at a speed below 5 mph (8 km/h) when shifting. Note: Some noise may be heard as the 4x4 system shifts or engages. This is normal. In order to reduce engagement noise, it is recommended that all shifts be performed at speeds below 5 mph (8 km/h). 2H (2WD) - For general on-road driving. Sends power to the rear wheels only. 4H (4x4 High) - For winter and off-road conditions. Sends power to front and rear wheels. This mode is not intended for use on dry pavement. N (Neutral) - Only used when towing the vehicle. 4L (4x4 Low) - For low-speed off-road applications that require extra power such as steep grades, deep sand or pulling a boat out of the water. Sends power to front and rear wheels. This mode is not intended for use on dry pavement. Shifting from 2H (2WD) to 4H (4x4 High) Engage the locking hubs by rotating the hub lock control from FREE to LOCK, then move the transfer case lever from 2H (2WD) to 4H (4x4 High) at a stop or a vehicle speed below 5 mph (8 km/h). • For proper operation, make sure that both indicator arrows on the hub are aligned, and that both hubs are set to LOCK. • Do not shift into 4H (4x4 High) with the rear wheels slipping. 2H 4H N 4L 299 2009 F-250/350/450/550 (f23) Owners Guide, 3rd Printing USA (fus)
