ENGINE COOLANT CHECK
WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury. WARNING:
Do not put coolant in
the windshield washer reservoir. If
sprayed on the windshield, coolant could
make it difficult to see through the
windshield. WARNING:
To reduce the risk of
personal injury, make sure the engine is
cool before unscrewing the coolant
pressure relief cap. The cooling system
is under pressure. Steam and hot liquid
can come out forcefully when you loosen
the cap slightly. WARNING:
Do not add coolant
further than the MAX mark.
When the engine is cold, check the
concentration and level of the coolant at
the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance
(page 422).
Note: Make sure that the coolant level is
between the
MIN and MAX marks on the
coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark. Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between
-29°F (-34°C) and -35°F
(-37°C). Coolant concentration should be
checked using a refractometer. We do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentration.
Adding Coolant WARNING:
Do not add engine
coolant when the engine is hot. Failure
to follow this instruction could result in
personal injury. WARNING:
Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury. WARNING:
Do not put coolant in
the windshield washer reservoir. If
sprayed on the windshield, coolant could
make it difficult to see through the
windshield.
Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty.
Note: Automotive fluids are not
interchangeable.

CHANGING THE ENGINE AIR
FILTER - 2.3L ECOBOOST™/
5.0L WARNING: To reduce the risk of
vehicle damage and personal burn
injuries, do not start your engine with the
air cleaner removed and do not remove
it while the engine is running.
Note: Failure to use the correct air filter
element may result in severe engine
damage. Your warranty may not cover
these damages.

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 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 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.
• 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 when
the sealant expires.
• 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 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, CD and
DVD player 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 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 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 in the vehicle.
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.
