The kit is located in the storage
compartment under the rear hatch,
forward of the rear wing. The kit consists
of an air compressor to re-inflate the tire
and a canister of sealing compound that
will effectively seal most punctures caused
by nails or similar objects. This kit provides
a temporary tire repair, allowing you to
drive your vehicle up to 120 mi (200 km)
at a maximum speed of 50 mph (80 km/h)
to reach a tire service location.
Note: The temporary mobility kit contains
enough sealant compound in the canister
for one tire repair only. See an authorized

General Information
WARNING: Failure to follow these
guidelines could result in an increased
risk of loss of vehicle control, injury or
death.
Note: Do not use the kit if you have severely
damaged a tire. Only seal punctures located
within the tire tread with the kit.
Do not attempt to repair punctures larger
than
0.2362 in (6 mm) or damage to the
tire's sidewall. The tire may not completely
seal.
Loss of air pressure may adversely affect
tire performance. For this reason:
Note: Do not drive the vehicle above
50 mph (80 km/h)
.
Note: Do not drive further than
120 mi
(200 km). Drive only to the closest
authorized Ford dealer or tire repair shop to
have your tire inspected.
• Drive carefully and avoid abrupt
steering maneuvers.
• Periodically monitor tire inflation
pressure in the affected tire; if the tire
is losing pressure, have the vehicle
towed on a flat bed.
• Read the information in the Tips for
Use of the Kit section to make sure safe
operation of the kit and your vehicle.
Tips for Use of the Kit
To ensure safe operation of the kit:
• Read all instructions and cautions fully.
• Before operating the kit, make sure
your vehicle is safely off the road and
away from moving traffic. Switch on
the hazard lights.
• Always set the parking brake to ensure
the vehicle does not move
unexpectedly. •
Do not remove any foreign objects,
such as nails or screws, from the tire.
• When using the kit, leave the engine
running (only if the vehicle is outdoors
or in a well-ventilated area) so the
compressor does not drain the
vehicle's battery.
• Do not allow the compressor to
operate continuously for more than 15
minutes. This will help prevent the
compressor from overheating.
• Never leave the kit unattended during
operation.
• Sealant compound contains latex.
Those with latex sensitivities should
use appropriate precautions to avoid
an allergic reaction.
• Keep the kit away from children.
• Only use the kit when the ambient
temperature is between -22°F (-30°C)
and 158°F (70°C).
• Only use the sealing compound before
the use-by date. The use-by date is on
a label on the sealant canister, which
you can see through the rectangular
viewing window on the bottom of the
compressor. Check the use-by date
regularly and replace the canister after
four years of non-use.
• Do not store the 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, an authorized Ford
dealer must replace the tire pressure
monitoring system sensor and valve
stem on the wheel.
• Operating the kit could cause an
electrical disturbance in radio
operation.

* When inflation only is required
for a tire or other objects, the
selector must be in the Air
position.
What to do When a Tire Is
Punctured
You can repair a tire puncture within the
tire's tread area in two stages with the kit.
• In the first stage, inflate the tire with a
sealing compound and air. After you
inflate the tire, you will need to drive
the vehicle a short distance (about 4 mi
(6 km) to distribute the sealant in the
tire.
• In the second stage, check the tire
pressure and adjust, if necessary, to the
vehicle's specified tire inflation
pressure.
First Stage: Inflating the Tire with
Sealing Compound and Air WARNING:
Do not stand directly
over the 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. WARNING:
Do not run the engine
when operating the air compressor
unless the vehicle is outdoors or in a
well-ventilated area.
Preparation: Park the vehicle in a safe, level
and secure area, away from moving traffic.
Switch the hazard lights on. Apply the
parking brake and switch the engine off.
Inspect the flat tire for visible damage. Sealant compound contains latex. Use
appropriate precautions to avoid any
allergic reactions.
Do not remove any foreign object that has
pierced the tire. If a puncture is located in
the tire sidewall, stop and call roadside
assistance.
1. Remove the valve cap from the tire
valve.
2. Unwrap the dual purpose hose (black tube) from the back of the compressor
housing.
3. Fasten the hose to the tire valve by turning the connector clockwise.
Tighten the connection securely. 4. Plug the power cable into the 12-volt
power point located on the right side
of the floor console.
5. Remove the warning sticker found on the casing/housing and place it on the
top of the instrument panel or the
center of the dash.

6. Start the vehicle and leave the engine
running so the compressor does not
drain the vehicle ’s battery. 7. Turn dial (A) clockwise to the sealant
position. Switch the kit on by pressing
the on/off button (B).
8. Inflate the tire to the pressure listed on
the tire label located on the driver's
door or the door jamb area. The initial
air pressure gauge reading may indicate
a value higher than the label pressure
while you pump the sealing compound
into the tire. This is normal and should
be no reason for concern. The pressure
gauge reading will indicate the tire
inflation pressure after about 30
seconds of operation. You should
check the final tire pressure with the
compressor turned OFF in order to get
an accurate pressure reading. 9. When the tire reaches the
recommended tire pressure, switch off
the kit, unplug the power cable, and
disconnect the hose from the tire valve.
Re-install the valve cap on the tire
valve and return the kit to the stowage
area.
10. Immediately and cautiously, drive the
vehicle 4 mi (6 km) to distribute the
sealant evenly inside the tire. Do not
exceed
50 mph (80 km/h).
11. After 4 mi (6 km), stop and check the
tire pressure. See Second Stage:
Checking Tire Pressure.

Note:
If you experience any unusual
vibration, ride disturbance or noise while
driving, reduce your speed until you can
safely pull off to the side of the road to call
for roadside assistance. Note: Do not
proceed to the second stage of this
operation.
Second Stage: Checking Tire
Pressure WARNING: The power plug may
get hot after use and should be handled
carefully when unplugging.
If you are proceeding from the First Stage:
Re-inflating the Tire with Sealing
Compound and Air section and have
injected sealant in the tire and the pressure
is below
20 psi (137 kPa), continue to the
next step.
Check the air pressure of your tires as
follows: 1. Remove the valve cap from the tire
valve.
2. Firmly screw the air compressor hose onto the valve stem by turning
clockwise.
3. Push and turn the dial clockwise to the
air position. 4. If required, switch on the compressor
and adjust the tire to the
recommended inflation pressure
shown on the tire label located on the
driver's door or door jamb area. You
should check the tire pressure with the
compressor turned OFF in order to get
an accurate pressure reading.
5. 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 kit to seal your tire, you will
need to replace the sealant canister. You
can obtain sealant canisters and spare
parts at an authorized Ford dealer. You can
dispose of empty sealant canisters at
home. However, you should dispose of
canisters still containing liquid sealant
through your local authorized Ford dealer
or tire dealer, or in accordance with local
waste disposal regulation.
Note: After you use the sealing compound,
the maximum vehicle speed is
50 mph
(80 km/h) and the maximum driving
distance is 120 mi (200 km). You should
inspect the sealed tire immediately.
You can check the tire pressure any time
within the 120 mi (200 km) by performing
the steps listed previously in the Second
Stage: Checking Tire Pressure procedure.

J.
Tire Ply Composition and
Material Used: Indicates the
number of plies or the number of
layers of rubber-coated fabric in
the tire tread and sidewall. Tire
manufacturers also must indicate
the ply materials in the tire and the
sidewall, which include steel,
nylon, polyester, and others.
K. Maximum Load: Indicates the
maximum load in kilograms and
pounds that can be carried by the
tire. See the Safety Compliance
Certification Label (affixed to
either the door hinge pillar,

position), for the correct tire
pressure for your vehicle.
L. Treadwear, Traction and
Temperature Grades:
*Treadwear The treadwear grade
is a comparative rating based on
the wear rate of the tire when
tested under controlled conditions
on a specified government test
course. For example, a tire graded
150 would wear one and one-half
times as well on the government
course as a tire graded 100. *Traction: The traction grades,
from highest to lowest are AA, A,
B, and C. The grades represent the
tire's ability to stop on wet
pavement as measured under
controlled conditions on specified
government test surfaces of
asphalt and concrete. A tire
marked C may have poor traction
performance.
*
Temperature: The temperature
grades are A (the highest), B and
C, representing the tire's
resistance to the generation of
heat and its ability to dissipate
heat when tested under controlled
conditions on a specified indoor
laboratory test wheel.
M. Maximum Inflation
Pressure:
Indicates the tire
manufacturers' maximum
permissible pressure or the
pressure at which the maximum
load can be carried by the tire. This
pressure is normally higher than
the vehicle manufacturer's
recommended cold inflation
pressure which can be found on
the Safety Compliance
Certification Label (affixed to
