Ford Expedition (2018 year). Manual — part 90

How Temperature Affects Your Tire
Pressure

The tire pressure monitoring system
monitors tire pressure in each pneumatic
tire. While driving in a normal manner, a
typical passenger tire inflation pressure
may increase about 2–4 psi (14–28 kPa)
from a cold start situation. If the vehicle is
stationary overnight with the outside
temperature significantly lower than the
daytime temperature, the tire pressure may
decrease about 3 psi (21 kPa) for a drop of
30°F (17°C) in ambient temperature. This
lower pressure value may be detected by
the tire pressure monitoring system as
being significantly lower than the
recommended inflation pressure and
activate the system warning light for low
tire pressure. If the low tire pressure
warning light is on, visually check each tire
to verify that no tire is flat. If one or more
tires are flat, repair as necessary. Check
the air pressure in the road tires. If any tire
is under-inflated, carefully drive the vehicle
to the nearest location where air can be
added to the tires. Inflate all the tires to
the recommended inflation pressure.

CHANGING A ROAD WHEEL

WARNING

If the tire pressure monitor sensor
becomes damaged it may not
function.

Note:

You should only use tire sealants in

roadside emergencies as they may cause
damage to the tire pressure monitoring
system sensor.

Note:

The tire pressure monitoring system

indicator light will illuminate when the spare
tire is in use. To restore the full function of
the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on this vehicle.

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.

Have a flat serviced by an authorized
dealer in order to prevent damage to the
system sensors. See Tire Pressure
Monitoring System

(page 359). Replace

the spare tire with a road tire as soon as
possible. During repairing or replacing of
the flat tire, have the authorized dealer
inspect the system sensor for damage.

Dissimilar Spare Wheel and Tire
Assembly Information

WARNING

Failure to follow these guidelines
could result in an increased risk of
loss of vehicle control, injury or death.

If you have a dissimilar spare wheel and
tire, then it is intended for temporary use
only. This means that if you need to use it,
you should replace it as soon as possible
with a road wheel and tire assembly that
is the same size and type as the road tires
and wheels that were originally provided
by Ford. If the dissimilar spare tire or wheel
is damaged, it should be replaced rather
than repaired.

A dissimilar spare wheel and tire assembly
is defined as a spare wheel and tire
assembly that is different in brand, size or
appearance from the road tires and
wheels.

Full-size dissimilar spare

When driving with the full-size dissimilar
spare wheel and tire assembly, do not:
•

Exceed 70 mph (113 km/h).

•

Use more than one dissimilar spare
wheel and tire assembly at a time.

•

Use snow chains on the end of the
vehicle with the dissimilar spare wheel
and tire assembly.

When driving with the full-size dissimilar
spare wheel and tire assembly, it is
recommended that you do not:
•

Exceed 50 mph (80 km/h) in 4WD.

•

Engage 4WD unless the vehicle is
stationary.

•

Use 4WD on dry pavement.

The usage of a full-size dissimilar spare
wheel and tire assembly can lead to
impairment of the following:
•

Handling, stability and braking
performance.

•

Comfort and noise.

•

Ground clearance and parking at curbs.

•

Winter weather driving capability.

•

Wet weather driving capability.

•

Four-wheel driving capability.

When driving with the full-size dissimilar
spare wheel and tire assembly additional
caution should be given to:
•

Towing a trailer.

•

Driving vehicles equipped with a
camper body.

•

Driving vehicles with a load on the
cargo rack.

Drive cautiously when using a full-size
dissimilar spare wheel and tire assembly
and seek service as soon as possible.

Location of the Spare Tire and
Tools

The spare tire is located under the vehicle,
just forward of the rear bumper. The jack,
swivel wrench and lug wrench are in the
following locations:

Under the vehicle, just forward of the rear

bumper

Tire Change Procedure

WARNINGS

Only use replacement tires and
wheels that are the same size, load
index, speed rating and type (such

as P-metric versus LT-metric or all-season
versus all-terrain) as those originally
provided by Ford. The recommended tire
and wheel size may be found on either the
Safety Compliance Certification Label
(affixed to either the door hinge pillar,

WARNINGS

door-latch post, or the door edge that
meets the door-latch post, next to the
driver's seating position), or the Tire Label
which is located on the B-Pillar or edge of
the driver's door. If this information is not
found on these labels, then you should
contact your authorized dealer as soon as

WARNINGS

possible. Use of any tire or wheel not
recommended by Ford can affect the
safety and performance of your vehicle,
which could result in an increased risk of
loss of vehicle control, vehicle rollover,
personal injury and death.

When one of the front wheels is off
the ground, the transmission alone
will not prevent the vehicle from

moving or slipping off the jack, even if the
transmission is in park (P).

To help prevent your vehicle from
moving when changing a wheel, shift
the transmission into park (P), set

the parking brake and use an appropriate
block or wheel chock to secure the wheel
diagonally opposite to the wheel being
changed. For example, when changing the
front left wheel, place an appropriate block
or wheel chock on the right rear wheel.

Do not get under a vehicle that is
supported by a jack.

Do not attempt to change a tire on
the side of the vehicle close to
moving traffic. Pull far enough off the

road to avoid the danger of being hit when
operating the jack or changing the wheel.

Always use the jack provided as
original equipment with your vehicle.
If using a jack other than the one

provided, make sure the jack capacity is
adequate for the vehicle weight, including
any vehicle cargo or modifications. If you
are unsure if the jack capacity is adequate,
contact the authorized dealer.

Switch off the running boards before
jacking or placing any object under
your vehicle. Never place your hand

between the extended running board and
your vehicle. A moving running board may
cause injury.

WARNINGS

Only use the spare wheel carrier to
stow the wheel provided with your
vehicle. Other wheel sizes could

cause the spare wheel carrier to fail if it
does not fit securely or is too heavy.

Note:

Passengers should not remain in the

vehicle when the vehicle is being jacked.

Park on a level surface, activate the hazard
flashers and set the parking brake. Then,
place the transmission in park (P) and turn
the engine off.

Removing the Jack and Tools

Note:

Pay close attention to the orientation

of the jack and tool kit bag, because it will
have to be reinstalled after changing the
tire.

1.

Open the liftgate, then locate the
access panel on the floor behind the
third row seat. Unlatch and remove the
panel.

2. Remove the wing nut by turning it

counterclockwise.

3. Remove the jack and tool kit bag from

the bracket.

4. Loosen the straps and remove the tool

kit bag from the jack.

Removing the Spare Tire

1.

Remove the swivel wrench from the
tool kit bag.

2. Open the spare tire winch access plug

at the bottom of the compartment for
the jack and tools tray.

3. Insert the swivel wrench through the

access hole in the floor and engage the
winch.

4. To remove the spare tire, turn the

handle counterclockwise until the tire
is lowered to the ground and the cable
is slightly slack.

5. Slide the retainer through the center of

the spare tire wheel and remove the
spare tire.
