air suspension FORD EXPEDITION 2007 3.G User Guide

•Wheels out of alignment
•Loose or worn suspension components
Variable assist steering
Your vehicle is equipped with variable assist power steering. At low
engine RPM, steering assist will adjust to reduce efforts and improve low
speed maneuverability. At high engine RPM, the assist will adjust to
improve steering feel at high speeds.
If the amount of effort required to steer your vehicle changes while
driving at a constant engine RPM, have the power steering system
checked by your authorized dealer.
AIR SUSPENSION SYSTEM (IF EQUIPPED)
The air suspension system is designed to improve ride, handling and
general vehicle performance during:
•Certain road conditions
•Steering maneuvers
•Braking
•Acceleration
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 toMessage centerin theDriver Controlschapter.
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.
On vehicles equipped with air suspension, turn the air
suspension and the ignition switch off prior to jacking, hoisting
or towing your vehicle.

Maintenance and Modifications
The suspension and steering systems on your vehicle have been designed
and tested to provide predictable performance whether loaded or empty
and durable load carrying capability. For this reason, Ford Motor
Company strongly recommends that you do not make modifications such
as adding or removing parts (such as lift kits or stabilizer bars) or by
using replacement parts not equivalent to the original factory equipment.
Any modifications to a vehicle that raise the center of gravity can make
it more likely the vehicle will roll over as a result of a loss of control.
Ford Motor Company recommends that caution be used with any vehicle
equipped with a high load or device (such as ladder racks or pickup box
cover).
Failure to maintain your vehicle properly may void the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
and adversely affect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
heavy off-road usage.
DRIVING THROUGH WATER
If driving through deep or standing
water is unavoidable, proceed very
slowly especially when the depth is
not known. Never drive through
water that is higher than the bottom
of the wheel rims (for cars) or the
bottom of the hubs (for trucks).
When driving through water, traction or brake capability may be limited.
Also, water may enter your engine’s air intake and severely damage your
engine or your vehicle may stall.Driving through deep water where
the transmission vent tube is submerged may allow water into the
transmission and cause internal transmission damage.
Once through the water, always dry the brakes by moving your
vehicle slowly while applying light pressure on the brake pedal.
Wet brakes do not stop the vehicle as quickly as dry brakes.

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
Your vehicle may be equipped with a conventional spare tire that is
different in one or more of the following: type, brand, size, speed rating
and tread design. If this is the case, this dissimilar spare tire is still rated
for your vehicle loads (GAWR and GVWR). This temporary spare tire is
not equipped with a Tire Pressure Monitor System (TPMS) sensor.

tools tray.
4. Insert the winch extension tool
assembly through the access hole in
the floor and engage the winch.
5. To remove the spare tire, turn the handle counterclockwise until the
tire is lowered to the ground and the cable is slightly slack.
6. Slide the retainer through the center of the spare tire wheel.
Tire change procedure
To help prevent the vehicle from moving when you change a tire,
be sure the parking brake is set, then block the wheels (both
front or both rear) on the opposite end of the vehicle from the wheel
being changed. If on a grade, block both opposite wheels on the
downward side of the hill.
If the vehicle slips off the jack, you or someone else could be
seriously injured.
On vehicles equipped with Air Suspension, turn OFF the Air
Suspension system prior to jacking, hoisting or towing your vehicle.
If your vehicle is equipped with air suspension, refer toMessage center
in theDriver Controlschapter for instructions on turning the air
suspension system off.
Refer to the instruction sheet (located in the rear floor compartment
behind the 3rd row seat with the jack tray tools assembly kit) for
detailed tire change instructions.

To lessen the risk of
personal injury, do not put
any part of your body under the
vehicle while changing a tire. Do
not start the engine when your
vehicle is on the jack. The jack is
only meant for changing the tire.
•Never use the front or rear
differential as a jacking point.
8. Remove the lug nuts with the lug wrench.
9. Replace the flat tire with the spare tire, making sure the valve stem is
facing outward. Reinstall the lug nuts until the wheel is snug against the
hub. Do not fully tighten the lug nuts until the wheel has been lowered.
10. Lower the wheel by turning the jack handle counterclockwise.
11. Remove the jack and fully
tighten the lug nuts in the order
shown and reinstall the wheel cover.
Refer toWheel lug nut torque
specificationslater in this chapter
for the proper lug nut torque
specification.
12. Unblock the wheels.
13. Put flat tire, jack, lug wrench
and tools away. Make sure the jack
bag is properly reinstalled around the jack and tools assembly tray with
the strap securely fastened. Be sure to tighten the wing nut sufficiently
so it does not rattle when you drive.
14. Turn on the air suspension system (if equipped). Refer toMessage
centerin theDriver Controlschapter for instructions on turning the air
suspension system on.

WRECKER TOWING
If you need to have your vehicle towed, contact a professional towing
service or, if you are a member of a roadside assistance program, your
roadside assistance service provider.
It is recommended that your vehicle be towed with a wheel lift or flatbed
equipment. Do not tow with a slingbelt. Ford Motor Company has not
approved a slingbelt towing procedure. Also, wrecker towing the vehicle
by the frame-mounted tow hooks is not recommended or advised.
If your vehicle is equipped with air suspension, the air suspension
control and the ignition must be turned off before being towed.
Refer toAir suspensionin theDrivingchapter.
On 4x2 vehicles, it is acceptable to tow the vehicle with the front wheels
on the ground (without dollies) and the rear wheels off the ground.
On 4x4 vehicles, it is recommended that your vehicle be towed with a
wheel lift and dollies or flatbed equipment with all the wheels off the
ground.

trailer or flatbed transport vehicle) your vehicle can be towed (all wheels
on the ground) under the following conditions:
Special Conditions:
•Release the parking brake.
•Turn the air suspension (if equipped) control to OFF.
•Turn the ignition to the OFF/UNLOCKED position.
•Place the transmission in N (Neutral).
If the vehicle’s battery is discharged, refer toAutomatic transmission
operationin theDrivingchapter for directions on how to move the
gearshift lever out of the P (Park) position, for proper towing.
