1997 FORD EXPEDITION ignition

and selection of two or four-wheel
drive modes.
The air suspension system places
the vehicle at its lowest height to
provide easy entry and exit when
the vehicle is parked, the ignition
is turned off and all doors are
closed.
The air suspension system raises
the vehicle approximately 2.5 cm
(1 in) to its normal ride position
when the ignition is turned on, the
transmission is initially shifted into
the drive or reverse mode and all
doors are closed.
In 4WD Low, the air suspension
system raises the vehicle an
additional 2.5 cm (1 in) above the
normal ride height to improve
vehicle ground clearance. However,
if the vehicle speed exceeds 40
km/h (25 mph), the system will
lower the vehicle to its normal ride
height to maximize ride comfort.
The vehicle will raise again if
vehicle speed is less than 13 km/h
(8 mph) for one minute. In 4WD
Low, do not exceed 56 km/h (35
mph).
As a safety consideration,
whenever a door is opened
(including the liftgate and liftgate
glass) the system memorizes and
maintains the height at the
moment the door was opened. The
system will maintain this height
until all doors are closed or until
vehicle speed exceeds 16 km/h (10
mph).

An on board air compressor and
solenoids are used to raise and
lower the vehicle. It is normal to
occasionally hear a buzz or clicking
from the vehicle even when the
ignition is turned off. The system
stays energized for 40 minutes
after the ignition is turned off to
compensate for any load changes
made after the vehicle is parked.
Air suspension service system
switch
The air suspension service system
switch is located below the glove
box at the lower right side of the
passenger foot well. Normal vehicle
operation does not require any
action by the driver. If this switch
is in the OFF position, the air
suspension system will not operate
and the CHECK SUSP warning
light in the instrument cluster will
illuminate.
On vehicles equipped with
Air Suspension, turn OFF
the Air Suspension switch prior
to jacking, hoisting or towing
your vehicle.
Check air suspension light
The warning and indicator light
CHECK SUSP illuminates when the
air suspension switch is turned off
or an air suspension system fault
has been detected.

If the light is displayed while
driving and the air suspension
system service switch is not turned
off, safely pull off the road at your
earliest convenience. Turn the
ignition switch from 4(On) to 3
(Off) and 4(On) again. If the
warning light reappears, turn the
air suspension switch off and have
the vehicle serviced by your dealer
or qualified service technician.
If the vehicle is loaded beyond the
recommended maximum payload,
the CHECK SUSP light may
illuminate. To correct this
condition, remove or redistribute
the payload according to the
recommended requirements and
follow the procedure outlined
above.
TRANSMISSION OPERATION

2(Second)Ð Use 2(Second) to
start-up on slippery roads or to
provide additional engine braking
on downgrades. Transmission
operates in first and second gears.
1(Low)Ð Use 1(Low) to provide
maximum engine braking on steep
downgrades. Upshifts can be made
by shifting to 2(Second) or to
D(Overdrive). Selecting 1(Low)
at higher speeds causes a shift to
2(Second), and will shift to 1(Low)
after vehicle decelerates to the
proper speed.
Brake-shift interlock
The brake-shift interlock feature
prevents you from shifting from
P(Park) unless the brake pedal is
depressed (with the ignition in the
On position). If you cannot move
the gearshift out of P(Park) with
the brake pedal depressed:
1. Turn ignition key to Off (3).
2. Apply the parking brake.

HAZARD LIGHTS CONTROL
Use only in an emergency to warn
traffic of vehicle breakdown,
approaching danger, etc. Depress
to activate all indicators
simultaneously. Depress again to
switch off. The warning lights can
be operated when the ignition is
off.
FUEL PUMP SHUT-OFF SWITCH
If the engine cranks but does not
start after a collision, the fuel
pump shut±off switch may have
been activated. The shut±off
switch is a device intended to stop
the electric fuel pump when your
vehicle has been involved in a
substantial jolt.com_hazard_switch.01

1. Turn the ignition switch to the
OFF position.
2. Check fuel system for leaks.
3. If no fuel leak is apparent, reset
the fuel pump shut-off switch by
pushing in the button on the
switch.
4. Turn the ignition switch to the
ON position. Pause for a few
seconds and return the key to the
OFF position.
5. Make a further check for leaks
in the fuel system.
FUSES AND RELAYS
If electrical components in the
vehicle are not working, a fuse
may have blown. Blown fuses are
identified by a broken element.
Check the appropriate fuses before
replacing any electrical
components.
Use the fuse puller tool provided
on the driver's compartment fuse
panel cover to replace the fuses.
Always replace a fuse with
one that has the specified
amperage rating. Using a fuse
with a higher amperage rating
can cause severe wire damage
and could start a fire.
