authorized dealer.
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)
This procedure is only required after tire rotation on vehicles
with different front and rear tire pressures.
WARNING:To determine if your vehicle requires two different
pressures - one for the front tires and one for the 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. SeeVehicle
Loadingin 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. Since tires need to be rotated to provide consistent
performance and maximum tire life, the Tire Pressure Monitoring System
needs to know when the tires are rotated to determine which set of tires
are on the front and which are on the rear. With this information, the
system can detect and properly warn of low tire pressures.
WARNING:Always perform the TPMS reset procedure after tire
rotation. If the system is not reset, it may not provide a low tire
pressure warning when necessary.

TPMS reset tool
A special TPMS reset tool to reset your TPMS after tire rotation is
provided with vehicles that have different front and rear tire pressures.
The tool is located with your Owner’s Guide materials.
Please take the tool with the
provided Velcro
strip 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
the 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.
If reset mode has been entered successfully, the horn will sound once,
the TPMS indicator will flash and the message center will displayTRAIN
LF TIRE.
If after repeated attempts to enter reset mode, the horn does not sound,
the TPMS indicator does not flash and the message center does not
display TRAIN LF TIRE, seek service from your authorized dealer.
TPMS reset sequence
The TPMS system needs to be reset starting with the left front tire in
the following clockwise order:
1. Left front tire
2. Right front tire
3. Right rear tire
4. Left rear tire

1.Left front tire:Place the TPMS reset tool against the left front tire
where the tire meets the rim, opposite from the valve stem (1) as shown.
This is where the sensor is located inside the rim.
The tool needs to be held against the tire sidewall opposite the
valve stem as illustrated with the arrow on the tool pointing
towards the rim; do not use the tool with the arrow pointing away
from the rim as it may not activate the sensor.
2. Press and release the green button and hold the tool to the tire
sidewall until the horn sounds. The red light on the TPMS reset tool will
illuminate while the tool is active. The horn will sound once within
10 seconds to indicate the process was successful.
Note:If a double horn chirp is heard, repeat the procedure. If a single
horn chirp is not heard, move the vehicle to rotate the wheels at least a
14-turn and repeat the procedure. If the horn does not sound while
attempting to reset any wheel, seek service from your authorized dealer.
3. Perform Steps 1 and 2 on the right front, right rear and finally the left
rear tires.
Successful completion of the reset procedure can be verified by turning
the ignition to OFF without the horn sounding. If two short beeps are
heard, the reset procedure was unsuccessful and must be repeated.
If after repeating the procedure two short beeps are heard when the key
is turned to OFF, seek assistance from your authorized dealer.

Rotation, pressure adjustment and TPMS reset example
The following example describes all the major steps involved in rotating
tires on a vehicle with different front and rear tire pressures. It
illustrates that the TPMS reset procedure needs to follow tire rotation
and pressure adjustment to avoid a possible false low tire warning.
Example:
A particular vehicle has the following recommended tire pressures: 50 psi
(345 kPa) front; 80 psi (552 kPa) rear.
Note:For your vehicle’s pressure, refer to the Safety Compliance
Certification Label located on the B-Pillar or the edge of your vehicle’s
driver’s door.
Before tire rotation
Sensor 1: 50 psi
Sensor 2: 50 psi
Sensor 3: 80 psi
Sensor 4: 80 psi

Sensor position following tire
rotation
Sensor 1: 50 psi
Sensor 2: 50 psi
Sensor 3: 80 psi
Sensor 4: 80 psi
Pressure adjustment without the
required TPMS reset procedure
Sensor 1: 80 psi
Sensor 2: 80 psi
Sensor 3: 50 psi
Sensor 4: 50 psi
In this situation, the TPMS warning
light will come on.
If the TPMS reset procedure is not performed after tire rotation and air
pressure adjustment, the TPMS telltale may illuminate for a false low tire
pressure condition.
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).

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
WARNING:Snow tires must be the same size, load index, speed
rating as those originally provided by Ford. Use of any tire or
wheel not recommended by Ford can affect the safety and
performance of your vehicle, which could result in an increased risk of
loss of vehicle control, vehicle rollover, personal injury and death.
Additionally, the use of non-recommended tires and wheels could
cause steering, suspension, axle or transfer case/power transfer unit
failure.
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.
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.
