TIRE PRESSURE MONITORING SYSTEM
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.
SeeInflating Your Tiresin this chapter. Failure to properly maintain
your tire pressure could increase the risk of tire failure, loss of control,
vehicle rollover and personal injury.
Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle placard or tire
inflation pressure label, you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS) that illuminates a low tire pressure
telltale when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible, and inflate them to the
proper pressure. Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle’s handling
and stopping ability.
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.
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.
Changing Tires with a Tire Pressure Monitoring System
Note:
Each road tire is equipped
with a tire pressure sensor located
inside the tire and wheel 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. SeeInflating Your Tiresin this chapter.
Understanding Your Tire Pressure Monitoring System
The tire pressure monitoring system measures pressure in your four road
tires and sends the tire pressure readings to your vehicle. The low tire
pressure warning light 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.
When Your Temporary Spare Tire Is Installed
When one of your road tires needs to be replaced with the temporary
spare, the system will continue to identify an issue to remind you that
the damaged road wheel and tire assembly needs to be repaired and put
back on your vehicle.

To restore the full function of the tire pressure monitoring system, have
the damaged road wheel and tire assembly repaired and remounted on
your vehicle.
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. See the following chart for
information concerning your tire pressure monitoring system:

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.

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 to 4 psi (14 to 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 approximately 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.

•Only use the sealing compound before the use by date. The use by
date is on the lower right hand corner of the label located on the
sealant canister.Note:Check the use by date regularly and replace
the canister after four years.
•Do not store the temporary mobility kit unsecured inside the
passenger compartment of the vehicle as it may cause injury during a
sudden stop or crash. Always store the kit in its original location.
•After sealant use, the tire pressure monitoring system sensor and
valve stem on the wheel must be replaced by an authorized Ford
dealer.
•When inflating a tire or other objects, use the black air hose only. Do
not use the transparent hose which is designed for sealant application
only.
•Operating the temporary mobility kit could cause an electrical
disturbance in radio, CD, and DVD player operation.
What to Do When a Tire Is Punctured
A tire puncture within the tire’s tread area can be repaired in two stages
with the temporary mobility kit:
•In the first stage, the tire will be reinflated with a sealing compound
and air. After the tire has been reinflated, you will need to drive the
vehicle a short distance (about 4 miles [6 kilometers]) to distribute the
sealant in the tire.
•In the second stage, check the tire pressure and adjust, if necessary,
to the vehicle’s tire inflation pressure.
First Stage: Reinflating the Tire with Sealing Compound and Air
WARNING:Do not stand directly over the temporary mobility
kit while inflating the tire. If you notice any unusual bulges or
deformations in the tire’s sidewall during inflation, stop and call
roadside assistance.
WARNING:If the tire does not inflate to the recommended tire
pressure within 15 minutes, stop and call roadside assistance.
Preparation
Park the vehicle in a safe, level and secure area, away from moving
traffic. Turn the hazard lights on. Apply the parking brake and turn the
motor off. Inspect the flat tire for visible damage.

Second Stage: Checking Tire Pressure
WARNING:If you are proceeding from theFirst Stage:
Reinflating the Tire with Sealing Compound and Airsection
and have injected sealant in the tire and the pressure is below 20 psi
(1.4 bar), stop and call roadside assistance. If tire pressure is above
20 psi (1.4 bar), continue to the next step.
WARNING:The power plug may get hot after use and should be
handled carefully while unplugging.
Check the air pressure of your tires as follows:
1. Remove the valve cap from the tire valve.
2. Unhook the black hose from the side of the compressor and fasten
firmly on the valve stem by turning clockwise.
3. Press down and turn the dial clockwise to the air position. Turn on the
kit by pressing the on/off button.
4. Adjust the tire to the
recommended inflation pressure
from the Tire Label located on the
driver’s door or door jamb area.
Note:The tire pressure has to be
checked with the compressor in the
OFF position to get the correct tire
pressure reading.
5. Turn the compressor off by
pressing the on/off button.
6. Unplug the hoses, re-install the valve cap on the tire and return the
kit to the stowage area.
What To Do After the Tire Has Been Sealed
After using the temporary mobility kit to seal your tire, you will need to
replace the sealant canister and clear tube (hose). Sealing compound
and spare parts can be obtained and replaced at an authorized Ford
Motor Company dealership or tire dealer. Empty sealant bottles may be
disposed of at home. However, liquid residue from the sealing compound
should be disposed by your local Ford Motor Company dealership or tire
dealer, or in accordance with local waste disposal regulations.
