Raising the Rear Wing
For routine cleaning, raise the wing.
Using the information display select the
following:
1. Rear wing deployment.
2. Select Raised.
After you have cleaned your vehicle, to
return the wing to the lowered position you
must drive the car at 15 mph (25 km/h) or
above. The wing will return to the lowered
position.
Note:
You cannot lower the wing when your
vehicle is stationary.
Exterior Plastic Parts
For routine cleaning we recommend
Motorcraft® Detail Wash. If tar or grease
spots are present, we recommend
Motorcraft® Bug and Tar Remover.
Under Hood
For removing black rubber marks from
under the hood we recommend
Motorcraft® Wheel and Tire Cleaner or
Motorcraft® Bug and Tar Remover.
WAXING
Note: If your vehicle has a matte paint
finish, do not wax your vehicle.
Regular waxing is necessary to protect your
car's paint from the elements. We
recommend that you wash and wax the
painted surface once or twice a year.
When washing and waxing, park your
vehicle in a shaded area out of direct
sunlight. Always wash your vehicle before
applying wax.
• Use a quality wax that does not contain
abrasives.
• Follow the manufacturer ’s instructions
to apply and remove the wax. •
Apply a small amount of wax in a
back-and-forth motion, not in circles.
• Do not allow wax to come in contact
with any non-body (low-gloss black)
colored trim. The wax will discolor or
stain the parts over time.
• Do not apply wax to glass areas.
• After waxing, your car's paint should
feel smooth, and be free of streaks and
smudges.
CLEANING THE ENGINE
Engines are more efficient when they are
clean because grease and dirt buildup keep
the engine warmer than normal.
When washing:
• Do not spray a hot engine with cold
water to avoid cracking the engine
block or other engine components.
• Spray Motorcraft® Engine Shampoo
and Degreaser on all parts that require
cleaning and pressure rinse clean. In
Canada, use Motorcraft Engine
Shampoo.
• Never wash or rinse the engine while it
is hot or running; water in the running
engine may cause internal damage.
• Never wash or rinse any ignition coil,
spark plug wire or spark plug well, or
the area in and around these locations.
• Never spray water on electrical
components such as modules,
connectors and fuse boxes. Cover all
electrical components before cleaning
to prevent water damage.

Brakes
•
Make sure the brakes and parking brake
release fully.
Tires
• To minimize flat spots on the tires,
inflate all four tires to the
recommended cold pressures listed on
the Safety Compliance Certification
label or Tire Label. When the vehicle is
taken out of storage, reset the tire
pressures as necessary to the
recommended levels listed on the
Safety Compliance Certification label
or Tire Label affixed to your vehicle.
Note: If you store your vehicle in a location
with low ambient temperatures, follow the
instructions for care of summer tires. See
Using Summer Tires (page 198).
Miscellaneous
• Move vehicles at least
25 ft (7.5 m)
every 15 days to lubricate working parts
and prevent flat spots in the tires.
Removing Vehicle From Storage
When your vehicle is ready to come out of
storage, do the following:
• Wash your vehicle to remove any dirt
or grease film build-up on window
surfaces.
• Check windshield wipers for any
deterioration.
• Check under the hood and engine cover
for any foreign material that may have
collected during storage such as mice
or squirrel nests.
• Check the exhaust for any foreign
material that may have collected
during storage.
• Check tire pressures and set tire
inflation per the Tire Label. •
Check brake pedal operation. Drive
your vehicle
15 ft (4.5 m) back and
forth with the brake lightly applied.
• Check fluid levels (including coolant,
oil and gas) to make sure there are no
leaks, and fluids are at recommended
levels.
See an authorized dealer if you have any
concerns or issues.

TIRE SEALANT AND INFLATOR
KIT
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 ¼ inch (6 millimeters) 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 WARNINGS
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. If the tire does not inflate to the
recommended tire pressure within
15 minutes, stop and call roadside
assistance. 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 (1.4 bar), 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.
