2021 FORD EXPLORER service indicator

Please note that the TPMS is not a
substitute for proper tire maintenance, and
it is the driver
’s responsibility to maintain
correct tire pressure, even if under-inflation
has not reached the level to trigger
illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence
will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be able
to detect or signal low tire pressure as
intended. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.

Changing Tires With a Tire
Pressure Monitoring System Note:
Each road tire is equipped with a tire
pressure sensor located inside the wheel
and tire assembly cavity. The pressure
sensor is attached to the valve stem. The
pressure sensor is covered by the tire and is
not visible unless the tire is removed. Take
care when changing the tire to avoid
damaging the sensor.
You should always have your tires serviced
by an authorized dealer.
Check the tire pressure periodically (at
least monthly) using an accurate tire
gauge. See
When Inflating Your Tires in
this chapter.

•
To reduce the chances of interference
from another vehicle, perform the
system reset procedure at least 3 ft
(1 m) away from another Ford Motor
Company vehicle undergoing the
system reset procedure at the same
time.
• Do not wait more than two minutes
between resetting each tire sensor or
the system can time-out and you have
to repeat the entire procedure on all
four wheels.
• A double horn sounds indicating the
need to repeat the procedure.
Performing the System Reset Procedure
Read the entire procedure before
attempting.
1. Drive the vehicle above
20 mph
(32 km/h) for at least two minutes,
then park in a safe location where you
can easily get to all four tires and have
access to an air pump.
2. Place the ignition in the off position and
keep the key in the ignition.
3. Cycle the ignition to the on position with the engine off.
4. Turn the hazard flashers on then off three times. You must accomplish this
within 10 seconds. If you successfully
enter the reset mode, the horn sounds
once, the system indicator flashes and
a message shows in the information
display. If this does not occur, please
try again starting at step 2. If after
repeated attempts to enter the reset
mode, the horn does not sound, the
system indicator does not flash and no
message shows in the information
display, seek service from your
authorized dealer. 5. Train the tire pressure monitoring
system sensors in the tires using the
following system reset sequence
starting with the left front tire in the
following clockwise order: Left front -
driver side front tire, Right front -
passenger side front tire, Right rear -
passenger side rear tire, Left rear -
driver side rear tire.
6. Remove the valve cap from the valve stem on the left front tire. Decrease the
air pressure until the horn sounds.
Note: The single horn tone confirms that
the sensor identification code has been
learned by the module for this position. If a
double horn is heard, the reset procedure
was unsuccessful, and you must repeat it.
7. Remove the valve cap from the valve stem on the right front tire. Decrease
the air pressure until the horn sounds.
8. Remove the valve cap from the valve stem on the right rear tire. Decrease the
air pressure until the horn sounds.
9. Remove the valve cap from the valve stem on the left rear tire. Decrease the
air pressure until the horn sounds.
Training is complete after the horn
sounds for the last tire trained, driver
side rear tire, the system indicator
stops flashing, and a message shows
in the information display.
10. Turn the ignition off. If two short horn
beeps are heard, the reset procedure
was unsuccessful and you must
repeat it. If after repeating the
procedure and two short beeps are
heard when the ignition is turned to
off, seek assistance from your
authorized dealer.

Set all four tires to the recommended
air pressure as indicated on the
Safety Compliance Certification
Label, affixed to either the door hinge
pillar, door-latch post, or the door
edge that meets the door-latch post,
next to the driver seating position or
Tire Label located on the B-Pillar or
the edge of the driver door.
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 illuminates 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 when 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 368). 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 us. If the dissimilar spare tire or wheel
is damaged, you should replace it rather
than repair it.
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.

When the oil change message appears in
the information display, it is time for an oil
change. Make sure you perform the oil
change within two weeks or 500 mi
(800 km) of the message appearing. Make
sure you reset the Intelligent Oil-Life
Monitor after each oil change. See
Oil
Change Indicator Reset (page 327).
If your information display resets
prematurely or becomes inoperative, you
should perform the oil change interval at
six months or
5,000 mi (8,000 km) from
your last oil change. Never exceed one year
or
10,000 mi (16,000 km) between oil
change intervals,
Your vehicle is very sophisticated and built
with multiple, complex performance
systems. Every manufacturer develops
these systems using different
specifications and performance features.
That is why it is important to rely upon your
dealership to properly diagnose and repair
your vehicle.
We have recommended maintenance
intervals for various parts and component
systems based upon engineering testing.
We rely upon this testing to determine the
most appropriate mileage for replacement
of oils and fluids to protect your vehicle at
the lowest overall cost to you and
recommends against maintenance
schedules that deviate from the scheduled
maintenance information.
We strongly recommend the use of only
our genuine manufactured or our
authorized re-manufactured replacement
parts engineered for your vehicle. Additives and Chemicals
This owner's manual and our Workshop
Manual list the recommended additives
and chemicals for your vehicle. We do not
recommend using chemicals or additives
not approved by us as part of your vehicle
’s
normal maintenance. Please consult your
warranty information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a
normal operating characteristic and, by
itself, does not necessarily indicate a
concern or that the fluid needs to be
changed. However, a qualified expert, such
as the factory-trained technicians at your
dealership, should inspect discolored fluids
that also show signs of overheating or
foreign material contamination
immediately.
Make sure to change your vehicle ’s oils and
fluids at the specified intervals or in
conjunction with a repair. Flushing is a
viable way to change fluid for many vehicle
sub-systems during scheduled
maintenance. It is critical that systems are
flushed only with new fluid that is the same
as that required to fill and operate the
system or using our approved flushing
chemical.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections every
month or at six-month intervals.
