failure of non-Ford parts may not be
covered by the Ford Warranty. For
additional information, refer to the terms
and conditions of the Ford Warranty.
SPECIAL NOTICES
New Vehicle Limited Warranty
For a detailed description of what your
vehicle
’s New Vehicle Limited Warranty
covers, see the Warranty Guide provided
to you along with your Owner ’s Manual.
Additional Warranty Information
Your vehicle carries the same warranty as
other Ford models. This information is
covered in its entirety in the Ford Warranty
Guide. You can obtain warranty service for
your vehicle at any authorized dealer
nationwide.
We design and build our vehicles for our
customers to drive as delivered from the
factory. The Ford Warranty Guide
discusses vehicle use and the installation
of aftermarket parts and their effect on
warranty coverage. See the Ford Warranty
Guide for complete information.
Using your vehicle on a dedicated road
course may result in degraded function
and failure of major systems such as the
engine, transmission and rear axle due to
the overheating of these systems. If you
intend to use your vehicle on a dedicated
road course, we suggest that you equip
your vehicle with racing-type coolers to
protect these three systems. In addition, if the vehicle is subjected to
dedicated road course use, we recommend
the following vehicle durability
maintenance:
•
Change your axle lubricant and friction
modifier after the initial (first) hour of
high-speed operation; thereafter
change the axle lubricant and friction
modifier every 12 hours (under these
conditions).
• Change your transmission oil after each
event where your vehicle is subjected
to individual on-track sessions
exceeding 15 minutes.
• Change your engine oil and filter after
each event.
Additionally, perform a multi-point
inspection on items specified in the
scheduled maintenance section of this
owner guide before and after dedicated
road course use. See General
Maintenance Information (page 414).
See the vehicle service manual for removal
and installation procedures. Replace with
Genuine Ford and Motorcraft™ service
parts as needed.
These actions may not necessarily protect
your powertrain from damage in dedicated
road course use. Subjecting your vehicle
to dedicated road course use even with
these proposed precautions may render
repairs non-reimbursable under the
warranty.
Special Instructions WARNINGS
Failure to follow the specific
warnings and instructions could
result in personal injury. See
Supplementary Restraints System
(page
36). Front seat mounted rear-facing child
or infant seats should never be

Disengaging the System
Press the brake pedal, press CNCL, or
press the clutch pedal (if equipped). The
last set speed displays in grey but will not
erase.
Overriding the System WARNING
Whenever the driver is overriding the
system by pressing the accelerator
pedal, the system will not
automatically apply the brakes to maintain
separation from any vehicle ahead. You can override the set speed and gap
distance by pressing the accelerator pedal.
When you override the system,
the green indicator light
illuminates and the lead vehicle
graphic does not show in the
information display.
The system will resume operation when
you release the accelerator pedal. The
vehicle speed will decrease to the set
speed, or a lower speed if following a
slower vehicle.
Changing the Set Speed
• Accelerate or brake to the desired
speed, then press and release
SET+.
• Press and hold SET+ or SET- until the
desired set speed shows on the
information display. The vehicle speed
will gradually change to the selected
speed.
• Press and release
SET+ or SET-. The
set speed will change in approximately
1 mph (2 km/h) increments.
The system may apply the brakes to slow
the vehicle to the new set speed. The set
speed will display continuously in the
information display while the system is
active. Resuming the Set Speed
Note:
Only use resume if you are aware of
the set speed and intend to return to it.
Press and release
RES. The vehicle will
return to the previously set speed. The set
speed will display continuously in the
information display while the system is
active.
Automatic Cancellation
The system is not functional at vehicle
speeds below 12 mph (20 km/h). An
audible alarm will sound and the
automatic braking releases if the vehicle
drops below this speed. The system will
cancel at low speeds if you switch off
electronic stability control.
Hilly Condition Usage
Note: An audible alarm will sound and the
system will shut down if it is applying brakes
for an extended period of time. This allows
the brakes to cool down. The system will
function normally again when the brakes
have cooled down.
You should select a lower gear position
when the system is active in situations
such as prolonged downhill driving on
steep grades, for example in mountainous
areas. The system needs additional engine
braking in these situations to reduce the
load on the vehicle ’s regular brake system
to prevent them from overheating.
Switching the System Off
Note: The set speed memory erases when
you switch off the system.
Press and release
OFF or turn off the
ignition.

Mustang (), enUSA, First Printing Cruise ControlE144529

All other system faults will display only
with a message in the information display.
See Information Messages (page 91).
Switching the Systems Off and On
You can temporarily switch off one or both
systems in the information display. See
General Information
(page 83). When
you switch off the Blind Spot Information
System, you will not receive alerts and the
information display will display a system
off message.
Note: The cross traffic alert system always
turns on whenever the ignition is switched
on. However, the Blind Spot Information
System will remember the last selected on
or off setting.
You cannot switch one or both systems
off when MyKey is used.
See Principle of
Operation (page 50).
You can also have one or both systems
switched off permanently at an authorized
dealer. Once switched off, only an
authorized dealer can switch the system
back on.
STEERING
Electric Power Steering WARNINGS
The electric power steering system
has diagnostic checks that
continuously monitor the system to
ensure proper operation. When a system
error is detected a steering message will
appear in the information display. The electric power steering system
has diagnostic checks that
continuously monitor the system to
ensure proper operation of the electronic
system. When an electronic error is
detected, a message will be displayed in
the information display. If this happens,
stop the vehicle in a safe place, and turn WARNINGS
off the engine. After at least 10 seconds,
reset the system by restarting the engine,
and watch the information display for a
steering message. If a steering message
returns, or returns while driving, take the
vehicle to your dealer to have it checked. Obtain immediate service if a system
error is detected. You may not notice
any difference in the feel of your
steering, but a serious condition may exist.
Failure to do so may result in loss of
steering control. Your vehicle has an electric power steering
system. There is no fluid reservoir to check
or fill.
If your vehicle loses electrical power while
you are driving (or if you switch the ignition
off), you can steer your vehicle manually,
but it takes more effort. Extreme
continuous steering may increase the effort
it takes for you to steer. This occurs to
prevent internal overheating and
permanent damage to your steering
system. If this should occur, you will neither
lose the ability to steer your vehicle
manually nor will it cause permanent
damage. Typical steering and driving
maneuvers allows the system to cool and
steering assist to return to normal.
Steering Tips
If the steering wanders or pulls, check for:
•
An improperly inflated tire.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components.
• Improper vehicle alignment.
A high crown in the road or high crosswinds
may also make the steering seem to
wander or pull.

Adding Engine Coolant
Note:
Do not use stop leak pellets, cooling
system sealants or additives as they can
cause damage to the engine cooling or
heating systems. Your warranty may not
cover these damages.
Note: During normal vehicle operation, the
engine coolant may change color from
orange to pink or light red.
As long as the engine coolant is clear and
uncontaminated, this color change does
not indicate that the engine coolant has
degraded, nor does it require that qualified
personnel drain the engine coolant, flush
the system or replace the engine coolant.
Do not mix different colors or types of
coolant in your vehicle. Mixing of engine
coolants may harm your engine ’s cooling
system. The use of an improper coolant
may harm engine and cooling system
components and may void the warranty.
Use prediluted engine coolant meeting the
Ford specification. See Capacities and
Specifications (page 267).
In case of emergency, you can add a large
amount of water without engine coolant
in order to reach a vehicle service location.
In this instance, qualified personnel:
1. Must drain the cooling system.
2. Chemically clean the coolant system with Motorcraft Premium Cooling
System Flush.
3. Refill with engine coolant as soon as possible.
Water alone, without engine coolant, can
cause engine damage from corrosion,
overheating or freezing.
Do not use the following as a coolant
substitute:
• Alcohol.
• Methanol. •
Brine.
• Any engine coolant mixed with alcohol
or methanol antifreeze or coolant.
Alcohol and other liquids can cause engine
damage from overheating or freezing.
Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of
the engine coolant.
When adding coolant:
1. Unscrew the cap slowly. Any pressure will escape as you unscrew the cap.
2. Add prediluted engine coolant meeting
the Ford specification. See
Capacities
and Specifications (page 267).
3. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle.
4. If necessary, add enough prediluted engine coolant to bring the coolant
level to the proper level.
Recycled Engine Coolant
Ford Motor Company does not recommend
the use of recycled engine coolant since a
Ford-approved recycling process is not yet
available.
Used engine coolant should be disposed
of in an appropriate manner. Follow your
community ’s regulations and standards
for recycling and disposing of automotive
fluids.

You have limited engine power when in the
fail-safe mode, so drive your vehicle with
caution. Your vehicle will not maintain
high-speed operation and the engine will
operate poorly.
Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:
1. Pull off the road as soon as safely
possible and switch off the engine.
2. Tow your vehicle to an authorized dealer.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and add if low.
5. Re-start the engine and drive your vehicle to an authorized dealer.
Note: Driving your vehicle without repair
increases the chance of engine damage.
Contact an authorized dealer as soon as
possible.
Engine Fluid Temperature
Management (If Equipped) WARNINGS
To reduce the risk of crash and injury,
be prepared that the vehicle speed
may reduce and the vehicle may not
be able to accelerate with full power until
the fluid temperatures reduce. Never remove the coolant reservoir
cap while the engine is running or hot.
Your vehicle can pull a trailer, but because
of the added load, your vehicle
’s engine
may temporarily reach higher
temperatures during severe operating
conditions such as ascending a long or
steep grade while pulling a trailer in high
temperatures. At this time, you may notice your engine
coolant temperature gauge needle move
toward the H and the POWER REDUCED
TO LOWER TEMP message may appear
in the information display.
You may notice a reduction in vehicle
speed caused by reduced engine power.
In order to manage the engine fluid
temperatures, your vehicle may enter this
mode if certain high-temperature and
high-load conditions take place. The
amount of speed reduction depends on
many factors such as vehicle loading,
towing, grade and ambient temperature.
If this occurs, there is no need to pull off
the road. You can continue to drive your
vehicle while this message is active.
The air conditioning may also cycle on and
off during severe operating conditions to
protect overheating of the engine. When
the engine coolant temperature decreases
to a normal operating temperature, the air
conditioning will turn on once again.
If the engine coolant temperature gauge
moves fully into the red (hot) area, or if the
coolant temperature warning or service
engine soon messages appear in your
information display:
1. Pull off the road as soon as safely possible and shift the transmission into
P
.
2. Leave the engine running until the coolant temperature gauge needle
moves away from the red (hot) area.
After several minutes, if the
temperature does not drop, follow the
remaining steps.
3. Switch the engine off and wait for it to
cool before checking the coolant level.
4. If the coolant level is normal, restart your engine and continue.

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.
• 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, CD and
DVD player operation.

When the oil change message appears in
the information display, it is time for an oil
change. Make sure you perform the oil
change within two weeks or 500 miles
(800 kilometers) of the message
appearing. Make sure you reset the
Intelligent Oil-Life Monitor after each oil
change. See General Information (page
83).
If your information display resets
prematurely or becomes inoperative, you
should perform the oil change interval at
six months or 5000 miles (8000
kilometers) from your last oil change.
Never exceed one year or 10000 miles
(16000 kilometers) between oil change
intervals.
Your vehicle is very sophisticated and built
with multiple, complex, performance
systems. Every manufacturer develops
these systems using different
specifications and performance features.
That is why it is important to rely upon your
dealership to properly diagnose and repair
your vehicle.
Ford Motor Company has recommended
maintenance intervals for various parts
and component systems based upon
engineering testing. Ford Motor Company
relies upon this testing to determine the
most appropriate mileage for replacement
of oils and fluids to protect your vehicle at
the lowest overall cost to you and
recommends against maintenance
schedules that deviate from the scheduled
maintenance information.
We strongly recommend the use of only
genuine Ford, Motorcraft or
Ford-authorized re-manufactured
replacement parts engineered for your
vehicle. Additives and Chemicals
This owner's manual and the Ford
Workshop Manual list the recommended
additives and chemicals for your vehicle.
We do not recommend using chemicals or
additives not approved by us as part of
your vehicle
’s normal maintenance. Please
consult your warranty information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a
normal operating characteristic and, by
itself, does not necessarily indicate a
concern or that the fluid needs to be
changed. However, a qualified expert, such
as the factory-trained technicians at your
dealership, should inspect discolored fluids
that also show signs of overheating or
foreign material contamination
immediately.
Make sure to change your vehicle ’s oils and
fluids at the specified intervals or in
conjunction with a repair. Flushing is a
viable way to change fluid for many vehicle
sub-systems during scheduled
maintenance. It is critical that systems are
flushed only with new fluid that is the same
as that required to fill and operate the
system or using a Ford-approved flushing
chemical.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections every
month or at six-month intervals.
