2019 FORD FLEX warning light

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
Solid warning light
Repair the damaged road wheel and tire
assembly and reinstall it on the vehicle
to restore system function. For a
description on how the system functions,
see
When your temporary spare tire
is installed in this section.
Spare tire in use
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.

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:
The use of tire sealant
may damage your tire pressure monitoring
system and should only be used in
roadside emergencies. If you must use a
sealant, the Ford Tire Mobility Kit sealant
should be used. The tire pressure
monitoring system sensor and valve stem
on the wheel must be replaced by an
authorized dealer after use of the sealant. WARNING:
See
Tire Pressure
Monitoring System (page 289). If the tire
pressure monitor sensor becomes
damaged, it will no longer 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 289). 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:

GENERAL INFORMATION
WARNING: Driving while distracted
can result in loss of vehicle control, crash
and injury. We strongly recommend that
you use extreme caution when using any
device that may take your focus off the
road. Your primary responsibility is the safe
operation of your vehicle. We recommend
against the use of any hand-held device
while driving and encourage the use of
voice-operated systems when possible.
Make sure you are aware of all applicable
local laws that may affect the use of
electronic devices while driving. Radio Frequencies and Reception
Factors
AM and FM frequencies are established by
the Federal Communications Commission
(FCC) and the Canadian Radio and
Telecommunications Commission (CRTC).
Those frequencies are:
•
AM: 530-1710 kHz
• FM: 87.9-107.9 MHz
Note: Listening to loud audio for long
periods of time could damage your hearing. Radio Reception Factors
The further you travel from an AM or FM station, the
weaker the signal and the weaker the reception.
Distance and strength
Hills, mountains, tall buildings, bridges, tunnels, freeway
overpasses, parking garages, dense tree foliage and
thunderstorms can interfere with the reception.
Terrain
When you pass a ground-based broadcast repeating
tower, a stronger signal may overtake a weaker one and
result in the audio system muting.
Station overload
CD and CD Player Information
Note: CD units play commercially pressed
4.7 in (12 cm) audio compact discs only. Due
to technical incompatibility, certain
recordable and re-recordable compact discs
may not function correctly when used in the
vehicle ’s CD player.
Note: Do not insert CDs with homemade
paper (adhesive) labels into the CD player
as the label may peel and cause the CD to
become jammed. You should use a
permanent felt tip marker rather than
adhesive labels on your homemade CDs.
Ballpoint pens may damage CDs. Ask an
authorized dealer for more information. Note:
Do not use any irregularly shaped
discs or discs with a scratch protection film
attached.
Always handle discs by their edges only.
Clean the disc with an approved CD
cleaner only. Wipe it from the center of
the disc toward the edge. Do not clean in
a circular motion.
Do not expose discs to direct sunlight or
heat sources for extended periods.

Multi-Point Inspection
In order to keep your vehicle running right,
it is important to have the systems on your
vehicle checked regularly. This can help
identify potential issues and prevent major
problems. We recommend having the
following multi-point inspection performed
at every scheduled maintenance interval
to help make sure your vehicle keeps
running great.
