Low fluid level
E158842
If the fluid level is below the MIN range
of the dipstick, add fluid to reach the
hash mark level.
Note:
If the fluid level is below the MIN
level, do not drive the vehicle. An
underfill condition may cause shift or
engagement concerns or possible
damage.
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).

Maintenance

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.

BRAKE FLUID CHECK
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.
POWER STEERING FLUID
CHECK
Your vehicle is equipped with an
electric power steering (EPS) system.
There is no fluid reservoir to check or
fill.
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.
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 329).
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.

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.
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/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.
281
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. Complete the following
procedure in order to restore the
settings:
1. With the vehicle at a completestop, 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 Audio System (page
124). Reset the power windows
bounce-back feature. See
Windows and Mirrors (page 88).
Reset the radio station presets.
See Audio System (page 124).
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 the vehicle at least 10 miles (16 kilometers) to completely
relearn the idle and fuel trim
strategy.
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.
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.
282
Maintenance

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

5. Locate the vertical adjuster oneach headlamp. Using a Phillips
#2 screwdriver, turn the adjuster
either clockwise or
counterclockwise in order to adjust
the vertical aim of the headlamp.
The horizontal edge of the brighter
light should touch the horizontal
reference line.
6. Close the hood and turn off the lamps.
Horizontal Aim Adjustment
Horizontal aim is not required for this
vehicle and is not adjustable.
CHANGING A BULB
Lamp Assembly Condensation
Exterior lamps are vented to
accommodate normal changes in
pressure. Condensation can be a
natural by-product of this design.
When moist air enters the lamp
assembly through the vents, there is
a possibility that condensation can
occur when the temperature is cold.
When normal condensation occurs, a thin film of mist can form on the
interior of the lens. The thin mist
eventually clears and exits through
the vents during normal operation.
Clearing time may take as long as 48
hours under dry weather conditions.
Examples of acceptable condensation
are:
• Presence of thin mist (no streaks,
drip marks or droplets).
• Fine mist covers less than 50% of the lens.
Examples of unacceptable moisture
(usually caused by a lamp water leak)
are:
• Water puddle inside the lamp.
• Large water droplets, drip marks or streaks present on the interior
of the lens.
Take your vehicle to a dealer for
service if any of the above conditions
of unacceptable moisture are present.
Replacing Bulbs
