FORD 2004 Expedition v.1 - Manual (Page 204)

If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
• Underinflated tire(s) on any wheel(s)
• Uneven vehicle loading
• High crown in center of road
• High crosswinds
• Wheels out of alignment
• Loose or worn suspension components
Speed sensitive steering
Your vehicle is equipped with engine speed sensitive steering. At higher
engine speeds associated with high vehicle speed, the steering assist will
decrease to improve steering feel.
If the amount of effort required to steer your vehicle changes while
maintaining a constant engine speed, have the power steering system
checked by your dealer or a qualified service technician.
AIR SUSPENSION SYSTEM (IF EQUIPPED)
The air suspension system is designed to improve ride comfort, vehicle
handling and general vehicle performance by adjusting the vehicle’s ride
height according to vehicle speed, weight added to or removed from the
vehicle and four-wheel drive (if equipped) operation. Normal vehicle
operation does not require any action by the driver.
When you enter the vehicle and the ignition is off, the air suspension will
have automatically lowered the vehicle to its lowest height to provide
easier entry. When a door or the liftgate is opened, the system
memorizes and maintains that height until either all doors are closed or
the vehicle’s speed exceeds 24 km/h (15 mph). The air suspension
system will then raise the vehicle’s height to its normal position when the
ignition is turned on, all doors are closed and the transmission is shifted
from P (Park).
When the vehicle is in motion, the air suspension will adjust the vehicle
ride height to normal operating position to maximize your ride comfort.
If your vehicle is equipped with four-wheel drive and you shift into 4WD
LOW, the air suspension will not move to it’s lowest position; instead, the
ride height is raised above the normal ride height position (at speeds
below 40 km/h [25 mph]) to improve ground clearance.
