Ford E-350 (2018 year). Manual — part 47

Customer action required

Possible cause

Low tire pressure

warning light

Make sure tires are at the proper pres-
sure. See Inflating your tires in this
chapter. After inflating your tires to the
manufacturer’s recommended pressure
as shown on the Tire Label (located on
the edge of driver’s door or the B-Pillar),
the vehicle must be driven for at least
two minutes over 20 mph (32 km/h)
before the light turns off.

Tire(s) under-inflated

If the tires are properly inflated and the
spare tire is not in use but the light
remains on, contact your authorized
dealer as soon as possible.

TPMS malfunction

When Inflating Your Tires

When putting air into your tires (such as at
a gas station or in your garage), the tire
pressure monitoring system may not
respond immediately to the air added to
your tires.

It may take up to two minutes of driving
over 20 mph (32 km/h) for the light to turn
off after you have filled your tires to the
recommended inflation pressure.

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

To determine the required
pressure(s) for your vehicle, see the
Safety Compliance Certification

Label (on the door hinge pillar, door-latch
post or the door edge that meets the
door-latch post, next to the driver seat) or
the Tire Label on the B-Pillar or the edge
of the driver door.

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 the vehicle.

Note: Do not use wheels or lug nuts
different than the original equipment, as this
may damage the wheel or mounting system.

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 187). 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 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.

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: This spare tire
begins with the letter T for tire size and
may have Temporary Use Only molded in
the sidewall.

2. Full-size dissimilar spare with label
on wheel: This spare tire has a label on
the wheel that states: THIS WHEEL AND
TIRE ASSEMBLY FOR TEMPORARY USE
ONLY.

When driving with one of the dissimilar
spare tires listed above, 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 one of the dissimilar spare tires
listed above 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.

3. Full-size dissimilar spare without
label on wheel

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 commercial car washing
equipment.

•

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

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.

•

All-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.

Tire Change 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).

WARNINGS

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.

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

Removing the flat wheel and tire

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.

E142551

3. Block both directions of the wheel that

is diagonally opposite to the wheel that
is being lifted.

4. Remove the spare tire and jack from

the storage location.

5. Remove the wheel trim (if equipped)

by inserting the tapered end of the lug
nut wrench behind the wheel cover or
hubcap and twist it off.

6. Loosen each wheel lug nut one-half

turn counterclockwise, but do not
remove them until the wheel is raise
off the ground.

Jacking location

Front axle jacking point: Place the jack
under the pin on the front surface of the
