Severe Climates
If you drive in extremely cold climates:
•
It may be necessary to have a Ford
authorized dealer increase the coolant
concentration above 50%.
• A coolant concentration of 60%
provides improved freeze point
protection. Engine coolant
concentrations above 60% decrease
the overheat protection characteristics
of the engine coolant and may cause
engine damage.
If you drive in extremely hot climates:
• It may be necessary to have a Ford
authorized dealer decrease the coolant
concentration to 40%.
• A coolant concentration of 40%
provides improved overheat protection.
Engine coolant concentrations below
40% will decrease the freeze and
corrosion protection characteristics of
the engine coolant and may cause
engine damage.
Vehicles driven year-round in non-extreme
climates should use prediluted engine
coolant for optimum cooling system and
engine protection.
What You Should Know About Fail-
Safe Cooling
If you deplete the engine coolant supply,
fail-safe cooling allows you to temporarily
drive your vehicle before you incur
incremental component damage. The
fail-safe distance depends on ambient
temperatures, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the engine
coolant temperature gauge will move to
the red (hot) area and: the coolant temperature
warning light will illuminate the service engine soon indicator
will illuminate.
If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating
cylinder operation. Each disabled cylinder
acts as an air pump and cools the engine.
When this occurs, your vehicle will still
operate. However:
• The engine power will be limited.
• This will disable the air conditioning
system.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you
can re-start your engine. Take your vehicle
to an authorized dealer as soon as possible
to minimize engine damage.
When Fail-Safe Mode Is Activated WARNINGS
Fail-safe mode is for use during
emergencies only. Operate your
vehicle in fail-safe mode only as long
as necessary to bring your vehicle to rest
in a safe location and seek immediate
repairs. When in fail-safe mode, your
vehicle will have limited power, will not be
able to maintain high-speed operation, and
may completely shut down without
warning, potentially losing engine power,
power steering assist, and power brake
assist, which may increase the possibility
of a crash resulting in serious injury. Never remove the coolant reservoir
cap while the engine is running or hot.

Mustang (), enUSA, First Printing Maintenance

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.

For longer, trouble-free operation, keep the
top of the battery clean and dry. Also,
make certain the battery cables are always
tightly fastened to the battery terminals.
If you see any corrosion on the battery or
terminals, remove the cables from the
terminals and clean with a wire brush. You
can neutralize the acid with a solution of
baking soda and water.
It is recommended that the negative
battery cable terminal be disconnected
from the battery if you plan to store your
vehicle for an extended period of time.
Because your vehicle
’s engine is
electronically controlled by a computer,
some control conditions are maintained
by power from the battery. When the
battery is disconnected or a new battery
is installed, the engine must relearn its idle
and fuel trim strategy for optimum
driveability and performance. Flexible fuel
vehicles (FFV) must also relearn the
ethanol content of the fuel for optimum
driveability and performance. To begin this
process:
1. With your vehicle at a complete stop, set the parking brake.
2. Put the gearshift in P(Park), turn off all
accessories.
3. Start the engine. Run the engine until it reaches normal operating
temperature.
4. Allow the engine to idle for at least one
minute.
5. Turn the air conditioning on and allow the engine to idle for at least one
minute. 6. Release the parking brake. With your
foot on the brake pedal and with the
air conditioning on, put your vehicle in
D
(Drive) and allow the engine to idle
for at least one minute.
• If you do not allow the engine to
relearn its idle trim, the idle quality
of your vehicle may be adversely
affected until the idle trim is
eventually relearned.
7. Drive your vehicle to complete the relearning process
•Your vehicle may need to be driven
10 miles (16 kilometers) or more to
relearn the idle and fuel trim
strategy along with the ethanol
content for flexible fuel vehicles.
• For flexible fuel vehicles, if you are
operating on E85, you may
experience poor starts or an
inability to start the engine and
driveability problems until the fuel
trim and ethanol content have been
relearned.
If the battery has been disconnected or a
new battery has been installed, the clock
and radio settings must be reset once the
battery is reconnected.
Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized standards
for disposal. Call your local authorized
recycling center to find out more about
recycling automotive batteries.
Battery Management System (If
Equipped)
The battery management system (BMS)
monitors battery conditions and takes
actions to extend battery life. If excessive
battery drain is detected, the system may
temporarily disable certain electrical
features to protect the battery. Those
electrical accessories affected include the
rear defrost, heated/cooled seats, climate
