If you drive in extremely hot climates:
• It may be necessary to have anauthorized dealer decrease the coolant
concentration to 40%.
• A coolant concentration of 40% provides improved overheat protection. Engine
coolant concentrations below 40%
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 the engine coolant supply is depleted, this
feature allows the vehicle to be driven
temporarily before incremental component
damage is incurred. The fail-safe distance
depends on outside temperatures, vehicle
load and terrain. How Fail-Safe Cooling Works
If the engine begins to overheat, the engine
coolant temperature gauge moves to the red
(hot) area and:
A high engine temperature
message appears in the
information display.
The service engine soon indicator
appears in the information display.
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.
If this occurs, your vehicle still operates.
However:
• The engine power becomes limited.
• The air conditioning system becomes disabled.
Continued operation increases the engine
temperature and the engine completely
shuts down, causing steering and braking
effort to increase. Once the engine temperature cools, the
engine can be re-started. 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.
291
Maintenance

Your vehicle has limited engine power when
in the fail-safe mode. Drive your vehicle with
caution. Your vehicle does not maintain
high-speed operation and the engine
operates 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 safelypossible 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.
See an authorized dealer as soon as
possible.AUTOMATIC TRANSMISSION
FLUID CHECK
6F35/HF35 transmission (If Equipped)
Note: Transmission fluid should be checked
by an authorized dealer. If required, fluid
should be added by an authorized dealer.
The automatic transmission does not have
a transmission fluid dipstick.
Refer to your scheduled maintenance
information for scheduled intervals for fluid
checks and changes. Your transmission does
not consume fluid. However, the fluid level
should be checked if the transmission is not
working properly, (For example: if the
transmission slips or shifts slowly) or if you
notice some sign of fluid leakage. See
Scheduled Maintenance (page 480).
Do not use supplemental transmission fluid
additives, treatments or cleaning agents. The
use of these materials may affect
transmission operation and result in damage
to internal transmission components.
6F50/6F55 Transmission (If Equipped)
WARNINGS
The dipstick cap and surrounding
components may be hot; gloves are
recommended.
Use gloves when moving the air filter
assembly. Components will be hot.
Note: Automatic transmission fluid expands
when warmed. To obtain an accurate fluid
check, drive the vehicle until it is warmed up
(approximately 20 miles [30 kilometers]). If
your vehicle has been operated for an
extended period at high speeds, in city traffic
during hot weather or pulling a trailer, the
vehicle should be turned off until normal
operating temperatures are reached to allow
the fluid to cool before checking. Depending
on vehicle use, cooling times could take up
to 30 minutes or longer.

Maintenance

Correct fluid level
E158843
The transmission fluid should be checked at
normal operating temperature 180°F-200°F
(82°C-93°C) on a level surface. The normal
operating temperature can be reached after
approximately 20 miles (30 kilometers) of
driving.
The transmission fluid level should be
targeted within the cross-hatch area if at
normal operating temperature 180°F-200°F
(82°C-93°C).High fluid level
E158844
If the fluid level is above the MAX range of
the dipstick, remove fluid to reach the
hashmark level.
Note:
Fluid level above the MAX level may
cause shift or engagement concerns or
possible damage. High fluid levels can be
caused by an overheating condition. If your
vehicle has been operated for an extended
period at high speeds, in city traffic during
hot weather or pulling a trailer, the vehicle
should be turned off until normal operating
temperatures are reached. Depending on
vehicle use, cooling times could take up to
30 minutes or longer. Adjusting Automatic Transmission Fluid
LevelsE158845

Fluid levels between the MIN and MAX lines
are within the normal operating range; there
is no need to add fluid. If the fluid levels are
outside of the normal operating range, the
performance of the system could be
compromised; seek service from your
authorized dealer immediately.
WASHER FLUID CHECK
WARNING
If you operate your vehicle in
temperatures below 40°F (5°C), use
washer fluid with antifreeze protection.
Failure to use washer fluid with antifreeze
protection in cold weather could result in
impaired windshield vision and increase the
risk of injury or accident.
Note: The front and rear washer systems
are supplied from the same reservoir. Add fluid to fill the reservoir if the level is low.
Only use a washer fluid that meets Ford
specifications. See Capacities and
Specifications (page 353).
State or local regulations on volatile organic
compounds may restrict the use of methanol,
a common windshield washer antifreeze
additive. Washer fluids containing
non-methanol antifreeze agents should be
used only if they provide cold weather
protection without damaging the vehicle’s
paint finish, wiper blades or washer system.
FUEL FILTER
Your vehicle is equipped with a lifetime fuel
filter that is integrated with the fuel tank.
Regular maintenance or replacement is not
needed.

CHANGING THE 12V BATTERY
WARNINGS
Batteries normally produce explosive
gases which can cause personal injury.
Therefore, do not allow flames, sparks or
lighted substances to come near the battery.
When working near the battery, always shield
your face and protect your eyes. Always
provide proper ventilation.
When lifting a plastic-cased battery,
excessive pressure on the end walls
could cause acid to flow through the vent
caps, resulting in personal injury and damage
to the vehicle or battery. Lift the battery with
a battery carrier or with your hands on
opposite corners.
WARNINGS
Keep batteries out of reach of children.
Batteries contain sulfuric acid. Avoid
contact with skin, eyes or clothing. Shield
your eyes when working near the battery to
protect against possible splashing of acid
solution. In case of acid contact with skin or
eyes, flush immediately with water for a
minimum of 15 minutes and get prompt
medical attention. If acid is swallowed, call a
physician immediately.
Your vehicle is equipped with a Motorcraft®
maintenance-free battery which normally
does not require additional water during its
life of service.
Note: If your battery has a cover or shield,
make sure it is reinstalled after the battery
has been cleaned or replaced.
Note: See an authorized dealer for low
voltage battery access, testing, or
replacement. When a low voltage battery replacement is
necessary, see an authorized dealer to
replace the low voltage battery with a Ford
recommended replacement low voltage
battery that matches the electrical
requirements of the vehicle
To ensure proper operation of the battery
management system (BMS), do not allow a
technician to connect any electrical device
ground connection directly to the low voltage
battery negative post. A connection at the
low voltage battery negative post can cause
inaccurate measurements of the battery
condition and potential incorrect system
operation.
Note:
If a person adds electrical or electronic
accessories or components to the vehicle,
the accessories or components may
adversely affect the low voltage battery
performance and durability and may also
affect the performance of other electrical
systems in the vehicle.
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.
297
Maintenance

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.
When a battery replacement is required, the
battery should only be replaced with a Ford
recommended replacement battery that
matches the electrical requirements of the
vehicle.
Because your vehicle’s engine is
electronically-controlled by a computer,
some engine control settings are maintained
by power from the low voltage battery. Some
engine computer settings, like the idle trim
and fuel trim strategy, optimize the
driveability and performance of the engine.
Some other computer settings, like the clock
and radio station presets, are also maintained
in memory by power from the low voltage
battery. When a technician disconnects and
connects the low voltage battery, these
settings are erased.Note:
Until you switch the ignition to the on
position, you will receive a message in your
information display stating that your vehicle
is not in park.
Complete the following procedure in order
to restore the settings:
1. With the vehicle at a complete stop, set the parking brake.
2. Shift the transmission into P.
3. Turn off all accessories.
4. Step on the brake pedal and start the vehicle.
5. Run the engine until it reaches normal operating temperature. While the engine
is warming up, complete the following:
Reset the clock. See Windows and
Mirrors (page 95). Reset the power
windows bounce-back feature. See
Windows and Mirrors (page 95). Reset
the radio station presets. See Windows
and Mirrors (page 95).
6. Allow the engine to idle for at least one minute. If the engine turns off, step on
the accelerator to start the engine. 7. While the engine is running, step on the
brake pedal and shift the transmission to
N.
8. Allow the engine to run for at least one minute by pressing on the accelerator
pedal.
9. Drive your vehicle at least 10 miles (16 kilometers) to completely relearn the idle
and fuel trim strategy.
Note: Certain features may not operate if
the Battery Monitor System is not reset with
a scan tool following a jump start or battery
replacement. Normal electrical accessory
operation should resume after your vehicle
is left undisturbed for 8 hours.
Note: If you do not allow the engine to
relearn the idle and fuel trim strategy, the
idle quality of your vehicle may be adversely
affected until the engine computer
eventually relearns the idle trim and fuel trim
strategy.
298
Maintenance

Note: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.
Note: 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.
CHECKING THE WIPER BLADES
