Driving This system keeps the rear of your vehicle at a constant level by automatically adding air or releasing air from the springs. If you exceed the load limit, the rear air suspension may not operate. The air suspension system will stay active for 40 minutes after the ignition is turned off to accommodate any load changes. (The air compressor may run when the vehicle is off; this is normal.) The air suspension system can be enabled or disabled through the message center. Refer to Message center in the Instrument Cluster chapter. If the system is off, the rear air suspension will not operate and will not raise (pump) or lower (vent) while the vehicle is not moving. However, if the system determines that the vehicle is low or high and needs to make a height adjustment while driving at speeds above 15 mph (24 km/h), the system will pump or vent as required. Normal vehicle operation does not require any action by the driver. WARNING: On vehicles equipped with air suspension, turn the air suspension and the ignition switch off prior to jacking, hoisting or towing your vehicle. LIMITED-SLIP AXLE (IF EQUIPPED) This axle provides added traction on slippery surfaces, particularly when one wheel is on a poor traction surface. Under normal conditions, the limited slip axle functions like a standard rear axle. Extended use of other than the manufacturer's specified size tires on a limited slip rear axle could result in a permanent reduction in effectiveness. This loss of effectiveness does not affect normal driving and should not be noticeable to the driver. PREPARING TO DRIVE WARNING: Utility vehicles have a significantly higher rollover rate than other types of vehicles. WARNING: In a rollover crash, an unbelted person is significantly more likely to die than a person wearing a seat belt. Utility vehicles and trucks have larger tires and increased ground clearance, giving the vehicle a higher center of gravity than a passenger car. 301 2010 Expedition (exd) Owners Guide, 3rd Printing USA (fus)

This system keeps the rear of your vehicle at a constant level by

the load limit, the rear air suspension may not operate. The air
suspension system will stay active for 40 minutes after the ignition is
turned off to accommodate any load changes. (The air compressor may

The air suspension system can be enabled or disabled through the

If the system is off, the rear air suspension will not operate and will not
raise (pump) or lower (vent) while the vehicle is not moving. However, if
the system determines that the vehicle is low or high and needs to make
a height adjustment while driving at speeds above 15 mph (24 km/h), the
system will pump or vent as required. Normal vehicle operation does not
require any action by the driver.
WARNING:
On vehicles equipped with air suspension, turn the
air suspension and the ignition switch off prior to jacking,
hoisting or towing your vehicle.

This axle provides added traction on slippery surfaces, particularly when
one wheel is on a poor traction surface. Under normal conditions, the
limited slip axle functions like a standard rear axle.
Extended use of other than the manufacturer’s specified size tires on a
limited slip rear axle could result in a permanent reduction in
effectiveness. This loss of effectiveness does not affect normal driving
and should not be noticeable to the driver.
PREPARING TO DRIVE
WARNING:
Utility vehicles have a significantly higher rollover
rate than other types of vehicles.
WARNING:
In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing a seat belt.
Utility vehicles and trucks have larger tires and increased ground
clearance, giving the vehicle a higher center of gravity than a passenger
car.
