2005 FORD EXPEDITION 4WD

NOTICE TO UTILITY VEHICLE AND TRUCK OWNERS
Utility vehicles and trucks handle
differently than passenger cars in
the various driving conditions that
are encountered on streets,
highways and off-road. Utility
vehicles and trucks are not designed
for cornering at speeds as high as
passenger cars any more than
low-slung sports cars are designed
to perform satisfactorily under
off-road conditions.
Utility vehicles have a significantly higher rollover rate than
other types of vehicles. To reduce the risk of serious injury or
death from a rollover or other crash you must:
•Avoid sharp turns and abrupt maneuvers;
•Drive at safe speeds for the conditions;
•Keep tires properly inflated;
•Never overload or improperly load your vehicle; and
•Make sure every passenger is properly restrained.
In a rollover crash, an unbelted person is significantly more likely
to die than a person wearing a seat belt. All occupants must
wear safety belts and children/infants must use appropriate restraints
to minimize the risk of injury or ejection.
Study yourOwner’s Guideand any supplements for specific information
about equipment features, instructions for safe driving and additional
precautions to reduce the risk of an accident or serious injury.
VEHICLE CHARACTERISTICS
4WD and AWD Systems (if equipped)
A vehicle equipped with AWD or 4WD (when you select the 4WD mode)
has the ability to use all four wheels to power itself. This increases
traction which may enable you to safely drive over terrain and road
conditions that a conventional two-wheel drive vehicle cannot.

Power is supplied to all four wheels
through a transfer case or power
transfer unit. 4WD vehicles allow
you to select different drive modes
as necessary. Information on shifting
procedures and maintenance can be
found in yourOwner’s Guide.You
should become thoroughly familiar
with this information before you operate your vehicle.
On some 4WD models, the initial shift from two-wheel drive to 4WD
while the vehicle is moving can cause a momentary clunk and ratcheting
sound. These sounds are normal as the front drivetrain comes up to
speed and is not cause for concern.
Do not become overconfident in the ability of 4WD and AWD
vehicles. Although a 4WD or AWD vehicle may accelerate better
than two-wheel drive vehicle in low traction situations, it won’t stop
any faster than two-wheel drive vehicles. Always drive at a safe speed.
How your vehicle differs from other vehicles
SUV and trucks can differ from
some other vehicles in a few
noticeable ways. Your vehicle may
be:
•Higher – to allow higher load
carrying capacity and to allow it
to travel over rough terrain
without getting hung up or
damaging underbody components.
•Shorter – to give it the capability
to approach inclines and drive
over the crest of a hill without
getting hung up or damaging
underbody components. All other
things held equal, a shorter
wheelbase may make your vehicle quicker to respond to steering
inputs than a vehicle with a longer wheelbase.

Sometimes irregular tire wear can be corrected by rotating the tires.
Note:If your tires show uneven wear ask a qualified technician at a
Ford or Lincoln/Mercury dealership to check for and correct any wheel
misalignment, tire imbalance or mechanical problem involved before tire
rotation.
Note:Your vehicle may be equipped with a dissimilar spare tire/wheel. A
dissimilar spare tire/wheel is defined as a spare tire and/or wheel that is
different in brand, size or appearance from the road tires and wheels. If
you have a dissimilar spare tire/wheel it is intended for temporary use
only and should not be used in a tire rotation.
Note:After having your tires rotated, inflation pressure must be checked
and adjusted to the vehicle requirements.
TIRE PRESSURE MONITORING SYSTEM (TPMS)(IF EQUIPPED)
When the Tire Pressure Monitoring
System warning light is lit, one or
more of your tires is significantly
under-inflated. You should stop and
check your tires as soon as possible,
and inflate them to the proper pressure as indicated on the vehicle’s tire

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 15 mph (24 km/h). 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 35 mph [56 km/h]) to improve ground clearance.
If a load is added to, or removed from the vehicle, the load leveling
feature of the air suspension system will adjust the suspension to keep
the vehicle at a constant level.
When exiting the vehicle, the air suspension will automatically lower the
vehicle to its lowest height to provide easier exit. You may hear a buzz or
click from the air suspension system when the ignition is turned off. 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 shut-off switch is
located behind an access panel on
the left rear quarter trim panel, near
the liftgate. To remove the panel,
turn the control counterclockwise.
On vehicles equipped with
air suspension, turn the air
suspension and the ignition switch
off prior to jacking, hoisting or
towing your vehicle.

CONTROL TRAC FOUR-WHEEL DRIVE (4X4) OPERATION
(IF EQUIPPED)
For important information regarding safe operation of this type
of vehicle, seePreparing to drive your vehiclein this chapter.
If equipped with the Control Trac 4x4 System, and 4L (4x4 LOW)
is selected while the vehicle is moving, the system will not
engage. This is normal and should be no reason for concern.
Before 4L (4x4 LOW) can be engaged, the vehicle must be
brought to a complete stop, the brake pedal depressed and the
transmission placed in N (Neutral).
The vehicle should not be operated in 4H (4x4 HIGH) or 4L (4x4 LOW)
on dry pavement. Doing so could result in difficult disengagement of the
transfer case, increased tire wear, decreased fuel economy and may
damage driveline components.
Your 4x4 features the heavy-duty Control Trac system which includes a
computer-operated transfer case. This unique system is interactive with
the road, continually monitoring and adjusting torque delivery to the
front and rear wheels to optimize vehicle control.
System indicator lights
The Control Trac system indicator lights illuminate only under the
following conditions. If these lights illuminate when driving in 2H or
A4WD, contact your Ford dealer as soon as possible.
•4X4 HIGH- momentarily
illuminates when the vehicle is
started. Illuminates when 4H is
selected.
•4X4 LOW– momentarily
illuminates when the vehicle is
started. Illuminates when 4L is
selected.

Positions of the Control Trac system
The Control Trac system functions
in four modes:
•2H (2WD HIGH)delivers power
to the rear wheels only. This is
appropriate for normal on-road
driving on dry pavement.
•A4WD (4X4 AUTO)provides
electronic control four-wheel
drive with power delivered to all
four wheels, as required, for
increased traction. This is appropriate for all on-road driving
conditions, such as dry road surfaces, wet pavement, snow or gravel.
•4H (4X4 HIGH)provides mechanically locked four-wheel drive power
to front and rear wheels. The “4X4 HIGH” light will illuminate in the
instrument cluster when this position is selected. This position is not
recommended for use on dry pavement. This position is only intended
for severe winter or off-road conditions, such as deep snow, ice or
shallow sand.
•4L (4X4 LOW)provides mechanically locked four-wheel drive when
extra power at reduced speeds is required. The “4X4 LOW” light will
illuminate in the instrument cluster when this position is selected.
This position is not recommended for use on dry pavement. Use this
position for off-road low-speed operation or when extra power is
required, such as climbing steep grades, going through deep sand or
pulling a boat out of the water.
Note:If your vehicle is equipped with AdvanceTrac
with RSC, the
AdvanceTrac
with RSC system will automatically turn off the stability
enhancement feature when you shift the Control Trac A4WD system into
4L (4X4 LOW). The brake traction enhancement feature will still be
enabled.
The AdvanceTrac
with RSC stability enhancement system can be
turned off manually by pressing the AdvanceTrac
with RSC button
(refer toAdvanceTrac
with Roll Stability Control (RSC) Stability
Enhancement Systemin this chapter) while operating in 2H, A4WD or
4H while driving in deep sand, very deep snow or more strenuous
off-road maneuvers. This will disable the engine management feature,
allowing the vehicle to maintain full power and enhanced momentum
through the obstacle.
