2008 FORD F150 brake sensor

The message center will display the last selected feature if there are no
more warning messages. This allows you to use the full functionality of
the message center after you acknowledge the warning by pressing the
RESET control and clearing the warning message.
Warning messages that have been reset are divided into two categories:
•They will reappear on the display ten minutes from the reset.
•They will not reappear until an ignition OFF-ON cycle has been
completed.
This acts as a reminder that these warning conditions still exist within
the vehicle.

Please take the tool with the
provided Velcrostrip on the back
and mount it in the bottom right
corner of your Owner’s Guide case
(as shown) for safe keeping.
If you find that the reset tool was
not provided when delivered, has
been lost or no longer functions
(the battery is not replaceable),
please contact your authorized
dealer to obtain a replacement.
To verify that your TPMS reset tool is working, press and release the
button on the center of the TPMS tool. The red light should illuminate
and remain on for approximately five (5) seconds. If the light does not
illuminate, the tool needs to be replaced.
TPMS reset tips
To reduce the chances of interference from another vehicle, TPMS reset
should be performed at least three feet (one meter) away from another
Ford Motor Company vehicle undergoing the TPMS reset procedure at
same time.
Do not wait more than two (2) minutes between resetting each tire
sensor or the system will timeout and the entire procedure will have to
be repeated on all four wheels.
A double horn chirp indicates the need to repeat the procedure.
TPMS reset procedure
Note:It is recommended that you read the entire procedure before
attempting.
Note:To enter the reset mode, Steps 1–5 MUST be completed within 60
seconds.
1. The key must be in the ignition and the ignition turned to OFF/LOCK.
Press and release the brake pedal.
2. Cycle the ignition from OFF/LOCK to RUN three (3) times ending in
the RUN position.DO NOTstart the engine.
3. Press and hold the brake pedal for two (2) seconds, then release.
4. Turn the ignition to OFF/LOCK (DO NOTremove the key.)
5. Cycle the ignition from OFF/LOCK to RUN three (3) times ending in
RUN.DO NOTstart the engine.

As in this example, the rear tires rotated to the front and properly
inflated to 50 psi (345 kPa) for the front axle would falsely illuminate the
low tire warning indicator as they are still trained for the rear positions
which require 80 psi (552 kPa).
Rotation, pressure adjustment
and successful completion of the
TPMS reset procedure
Sensor 1: 80 psi
Sensor 2: 80 psi
Sensor 3: 50 psi
Sensor 4: 50 psi
Tire rotation and air pressure
adjustment followed by sensor
resetting will ensure the system is properly programmed for vehicles
with different front and rear tire pressures and reduce the risk of a false
low tire warning.
In this situation, the TPMS warning light will be off.
SNOW TIRES AND CHAINS
Snow tires must be the same size and grade as the tires you
currently have on your vehicle.
The tires on your vehicle have all weather treads to provide traction in
rain and snow. However, in some climates, you may need to use snow
tires and chains. If you need to use chains, it is recommended that steel
wheels (of the same size and specifications) be used, as chains may chip
aluminum wheels.
Note: Do not place chains on the following tires sizes: P265/60R18,
P275/65R18, LT275/65R18, P275/55R20, and P275/45R22.
Follow these guidelines when using snow tires and chains:
•Use only SAE Class S chains.
•Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
•Drive cautiously. If you hear the chains rub or bang against your
vehicle, stop and re-tighten the chains. If this does not work, remove
the chains to prevent damage to your vehicle.
•If possible, avoid fully loading your vehicle.

CHANGING THE TIRES
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.
Note:The tire pressure monitoring system (TPMS) indicator light will
illuminate when the spare tire is in use. To restore the full functionality
of the monitoring system, all road wheels equipped with tire pressure
monitoring sensors must be mounted on the vehicle.
Have a flat serviced by an authorized dealer in order to prevent damage
to the TPMS sensors, refer toTire Pressure Monitoring System
(TPMS)in theTires, Wheels and Loadingchapter. Replace the spare
tire with a road tire as soon as possible.
The use of tire sealants may damage your Tire Pressure
Monitoring System and should not be used.
Refer toTire Pressure Monitoring System (TPMS)in the
Tires, Wheels and Loadingchapter for important information. If
the tire pressure monitor sensor becomes damaged, it will no longer
function.
Dissimilar spare tire/wheel information
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 tire/wheel, 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 tire/wheel 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 tire/wheel is defined as a spare tire and/or wheel 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 TIRE AND WHEEL FOR
TEMPORARY USE ONLY”
