FORD 2009 F-150 v.1 - Manual (Page 295)

4L (4WD Low)– Uses extra gearing to provide maximum power to all
four wheels at reduced speeds. Intended only for off-road applications
such as deep sand, steep grades or pulling heavy objects. The shift lever
will not engage 4L (4X4 LOW) until the transmission is in N (neutral)
and the vehicle is moving below 3 mph (5 km/h); this is normal and
should be no reason for concern. Refer to Shifting to/from 4L (4WD
Low) for proper operation.
Shifting between 2H (2WD high) and 4H (4WD high)
• Move the transfer case lever between 2H (2WD High) and 4H (4WD
High) at a stop or any forward speed.
Note: Do not perform this operation if the rear wheels are slipping.
Note: Some noise may be heard as the system shifts or engages; this is
normal.
Shifting to/from 4L (4WD Low)
1. Bring the vehicle to a speed of 3 mph (5 km/h) or less.
2. Place the transmission in N (Neutral).
3. Move the transfer case lever through N (Neutral) directly to the
desired position.
• If the transfer case will not engage into 4L (4WD Low) do not force
the lever. Allow the vehicle to coast at a speed below 3 mph
(5 km/h), then repeat Steps 2 and 3.
Note: Some noise may be heard as the system shifts or engages; this is
normal.
Note: For proper operation in 4WD Low, ensure the transfer case shift
lever is moved entirely rearward in to the 4L (4WD Low) position and
that the 4x4 Low light is displayed in the message center.
Note: Ideal 4L (4WD Low) shift conditions occur when the vehicle is
rolling at a speed below 3 mph (5 km/h) and the transmission is in N
(Neutral).
Using the N (Neutral) position
The transfer case N (Neutral) position overrides the transmission
and puts the vehicle in neutral regardless of transmission
gearshift lever position. The vehicle can move forward or
backward.
This position should only be used when towing the vehicle.
