Ford E-250 (2009 year). Manual — part 40

The Tire Pressure Monitoring System complies with part 15 of the FCC
rules and with RSS-210 of Industry Canada. Operation is subject to the
following two conditions: (1) This device may not cause harmful
interference, and (2) This device must accept any interference received,
including interference that may cause undesired operation.

WARNING: The Tire Pressure Monitoring System is NOT a
substitute for manually checking tire pressure. The tire pressure

should be checked periodically (at least monthly) using a tire gauge,
see Inflating your tires in this chapter. Failure to properly maintain
your tire pressure could increase the risk of tire failure, loss of control,
vehicle rollover and personal injury.

Changing tires with TPMS

Each road tire is equipped with
a tire pressure sensor fastened
to the inside rim of the wheel.
The pressure sensor is covered
by the tire and is not visible
unless the tire is removed. The
pressure sensor is located
opposite (180 degrees) from the
valve stem. Care must be taken
when changing the tire to avoid
damaging the sensor. It is
recommended that you always have
your tires serviced by an authorized
dealer.

The tire pressure should be checked
periodically (at least monthly) using
an accurate tire gauge, refer to
Inflating your tires in this chapter.

Understanding your Tire Pressure Monitoring System (TPMS)

The Tire Pressure Monitoring System measures pressure in your four
road tires and sends the tire pressure readings to your vehicle. The Low
Tire Warning Lamp will turn ON if the tire pressure is significantly low.
Once the light is illuminated, your tires are under inflated and need to be
inflated to the manufacturer’s recommended tire pressure. Even if the
light turns ON and a short time later turns OFF, your tire pressure still
needs to be checked. Visit www.checkmytires.org for additional
information.

When your temporary spare tire is installed

When one of your road tires needs to be replaced with the temporary
spare, the TPMS system will continue to identify an issue to remind you
that the damaged road wheel/tire needs to be repaired and put back on
your vehicle.

To restore the full functionality of the Tire Pressure Monitoring System,
have the damaged road wheel/tire repaired and remounted on your
vehicle. For additional information, refer to Changing tires with TPMS
in this section.

When you believe your system is not operating properly

The main function of the Tire Pressure Monitoring System is to warn you
when your tires need air. It can also warn you in the event the system is no
longer capable of functioning as intended. Please refer to the following
chart for information concerning your Tire Pressure Monitoring System:

1. Check your tire pressure to ensure tires
are properly inflated; refer to Inflating
your tires in this chapter.
2. After inflating your tires to the
manufacturer’s recommended inflation
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 will turn OFF.

Spare tire in use Your temporary spare tire is in use. Repair

the damaged road wheel/tire and reinstall
it on the vehicle to restore system
functionality. For a description on how the
system functions, refer to When your
temporary spare tire is installed in this
section.

If your tires are properly inflated and your
spare tire is not in use and 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 (TPMS) monitors tire pressure in
each pneumatic tire. While driving in a normal manner, a typical
passenger tire inflation pressure may increase approximately 2 to 4 psi
(14 to 28 kPa) from a cold start situation. If the vehicle is stationary
over night with the outside temperature significantly lower than the
daytime temperature, the tire pressure may decrease approximately 3 psi
(20.7 kPa) for a drop of 30° F (16.6° C) in ambient temperature. This
lower pressure value may be detected by the TPMS as being significantly
lower than the recommended inflation pressure and activate the TPMS
warning 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 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.

TPMS reset procedure (if applicable)

The TPMS reset tool is ONLY provided for vehicles with different
front and rear tire pressures. The TPMS reset procedure needs to
be performed after tire rotation only on these vehicles.

WARNING: To determine if your vehicle has different
recommended pressures for the front and rear tires, refer to the

Safety Compliance Certification Label or Tire Label which is located on
the B-Pillar or the edge of the driver’s door. See Vehicle Loading in
this chapter for more information.

Overview

To provide the vehicle’s load carrying capability, some trucks require
different recommended tire pressures in the front tires as compared to
the rear tires. The Tire Pressure Monitoring System (TPMS) equipped on
these vehicles is designed to illuminate the Low Tire Pressure Warning
indicator at two different pressures; one for the front tires and one for
the rear tires.
