Ford Fusion (2018 year). Manual — part 75

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

WARNINGS

Do not use tire sealants as they may
damage the tire pressure monitoring
system.

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

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 the 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
tire pressure monitoring system sensors.
See Tire Pressure Monitoring System
(page 299). Replace the spare tire with a
road tire as soon as possible. During
repairing or replacing of the flat tire, have
an authorized dealer inspect the tire
pressure monitoring 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.

Important Use of Spare Wheel

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
and can be one of three types:
1.

T-type mini-spare.

*

2. Full-size dissimilar spare with label on

wheel.

**

3. Full-size dissimilar spare without label

on wheel.

*

This spare tire begins with the letter T for

tire size and may have Temporary Use Only
molded in the sidewall.

**

This spare tire has a label on the wheel

that states: THIS WHEEL AND TIRE
ASSEMBLY FOR TEMPORARY USE ONLY.

Driving with a T-type Mini-spare or Full-
size Dissimilar Spare With Label on Wheel

Do not:
•

Exceed 50 mph (80 km/h).

•

Load the vehicle beyond maximum
vehicle load rating listed on the Safety
Compliance Label.

•

Tow a trailer.

•

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

•

Use more than one dissimilar spare tire
at a time.

•

Use commercial car washing
equipment.

•

Try to repair the dissimilar spare tire.

Use of the above dissimilar spare wheel at
any one wheel location 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.

•

All-wheel driving capability (if
applicable).

Driving With a 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 commercial car washing
equipment.

•

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

Use of the above dissimilar spare wheel at
any one wheel location 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.

•

All-wheel driving capability.

Give additional caution to the following
when driving with the full-size dissimilar
spare wheel and tire assembly:
•

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.

Changing a Road Wheel Procedure

WARNINGS

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 work on your vehicle when
the jack is the only support. If the
vehicle slips off the jack, you or

someone else could be seriously injured.

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.

Note: Passengers should not remain in your
vehicle when the vehicle is being jacked.

1.

Park on a level surface, set the parking
brake and activate the hazard flashers.

2. Place the transmission in park (P) and

turn the engine off. For vehicles with a
manual transmission, place the
transmission in reverse (R) after the
engine is turned off.

E175447

3. Block both the front and rear of the

wheel diagonally opposite the flat tire.
For example, if the left front tire is flat,
block the right rear wheel.

4. Remove the carpeted wheel cover.

5. Remove the spare tire bolt securing the

spare tire by turning it
counterclockwise.

6. Remove the spare tire from the spare

tire compartment.

E178186

7.

Remove the lug wrench and jack from
the spare tire compartment.

E175694

8. To remove the wrench from the jack,

turn the hex nut on the jack
counterclockwise. This will lower the
jack and loosen the mechanical lock.

E224246

9. If your vehicle has a wheel trim, use the

tool supplied to remove it and access
the lug nuts.

10.

Loosen each wheel lug nut one-half
turn counterclockwise, but do not
remove them until the wheel is raised
off the ground.

E145908

11.

The vehicle jacking points are shown
here, and can be identified by the
triangle markings on the molding. The
triangle marking may be located on
the side or the underside of the
molding. The jacking points are
identified on vehicles without
moldings by a pair of arrows on the
metal flange pointing to the jacking
point between them. Details are
depicted on the warning label on the
jack.

E174939

12.

Place the jack at the jacking point
next to the tire you are changing. Turn
the jack handle clockwise until the
wheel is completely off the ground.

13.

Remove the lug nuts with the lug
wrench.
