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 complete stop, set the parking brake.
2. Shift into park (P).
3. Switch off all accessories.
4. Fully press 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 278). Reset the power
windows bounce-back feature. See
Windows and Mirrors
(page 81).
Reset the radio station presets. See
Audio System
(page 278).
6. Allow the engine to idle for at least one
minute. If the engine turns off, press
the accelerator pedal to start the
engine.
7. While the engine is running, press the brake pedal and shift into neutral (N).
8. Allow the engine to run for at least one
minute by pressing on the accelerator
pedal.
9. Drive the vehicle at least 12 mi (20 km)
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.
Make sure that you dispose of old batteries
in an environmentally friendly way. Seek
advice from your local authority about
recycling old batteries.
CHECKING THE WIPER
BLADES Run the tip of your fingers over the edge of
the blade to check for roughness.
Clean the wiper blades with washer fluid
or water applied with a soft sponge or
cloth.
CHANGING THE WIPER
BLADES
Note:
If streaks or smears appear on the
windshield, clean the windshield and the
wiper blades.
See Cleaning the Windows
and Wiper Blades (page 236). If that does
not resolve the issue, install new wiper
blades.

Service Position
Set the windshield wipers in the service
position to change the wiper blades. The
windshield wipers return to the starting
position when you switch the ignition on.
Note:
You can use the service position in
winter to provide easier access to the wiper
blades for freeing them from snow and ice.
Make sure the windshield is free from snow
and ice before you switch the ignition on.
1. Switch the ignition on. 2. Switch the ignition off and press and
hold the wiper lever in position A within
three seconds.
3. Release the wiper lever when the windshield wipers reach the service
position. Note:
You can also move the wiper arms
to the service position manually when the
ignition is off. Do not move the wiper arms
to the service position manually when the
ignition is on. The wiper arms lock when you
switch the ignition on.
Changing the Windshield Wiper Blades
1. Pull the wiper blade and arm away from the glass. Note:
Make sure that the wiper arm does
not spring back against the glass when the
wiper blade is not attached.
2. Press the locking buttons together.
3. Rotate and remove the wiper blade.
4. Install in the reverse order.
Note: Make sure that the wiper blade locks
into place.
Changing the Rear Window Wiper

ADJUSTING THE HEADLAMPS
Vertical Aim Adjustment
If your vehicle has been involved in a crash,
have the aim of the headlamp beam
checked by an authorized dealer. Headlamp Aiming Target 8 ft (2.4 m)
A
Ground to the center of the
headlamp low beam bulb
B
25 ft (7.6 m)
C
Horizontal reference line
D
Vertical Aim Adjustment Procedure
1. Park your vehicle on level ground approximately 25 ft (7.6 m) from a wall
or screen.
2. Measure the distance from the ground
to the center of the headlamp low
beam bulb and mark an
8 ft (2.4 m)
long horizontal reference line on the
wall or screen at this height.

Note:
There may be an identifying mark on
the lens to help you locate the center of the
bulb.
Note: To see a clearer light pattern while
adjusting one headlamp, you may want to
block the light from the other headlamp.
3. Switch on the low beam headlamps and open the hood. 4. On the wall or screen you will observe
a flat zone of high intensity light
located at the top of the beam pattern.
If the top edge of the flat zone of high
intensity light is not on the horizontal
reference line, adjust the aim of the
headlamp beam. 5. Locate the vertical adjuster on each
headlamp. Use a suitable tool, for
example a screwdriver or hexagonal
socket, to turn the adjuster clockwise
or counterclockwise 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 switch off the lamps.
Horizontal Aim Adjustment
The horizontal aim of the headlamp beam
on your vehicle is not adjustable.

•
Do not allow wax to come in contact
with any non-body (low-gloss black)
colored trim. The wax will discolor or
stain the parts over time.
•Roof racks.
• Bumpers.
• Grained door handles.
• Side moldings.
• Mirror housings.
• Windshield cowl area.
• Do not apply wax to glass areas.
• After waxing, your car's paint should
feel smooth, and be free of streaks and
smudges.
CLEANING THE ENGINE
Engines are more efficient when they are
clean because grease and dirt buildup keep
the engine warmer than normal.
When washing:
• Take care when using a power washer
to clean the engine. The high-pressure
fluid could penetrate the sealed parts
and cause damage.
• Do not spray a hot engine with cold
water to avoid cracking the engine
block or other engine components.
• Spray Motorcraft Engine Shampoo and
Degreaser on all parts that require
cleaning and pressure rinse clean. In
Canada, use Motorcraft Engine
Shampoo.
• Never wash or rinse the engine while it
is hot or running; water in the running
engine may cause internal damage. •
Never wash or rinse any ignition coil,
spark plug wire or spark plug well, or
the area in and around these locations.
• Cover the battery, power distribution
box, and air filter assembly to prevent
water damage when cleaning the
engine.
CLEANING THE WINDOWS AND
WIPER BLADES
Car wash chemicals and environmental
fallout can result in windshield and wiper
blade contamination. Dirty windshield and
wipers will result in poor windshield wiper
operation. Keep the windshield and wiper
blades clean to maintain windshield wiper
performance.
To clean the windshield and wiper blades:
• Clean the windshield with a
non-abrasive glass cleaner. When
cleaning the interior of the windshield,
avoid getting any glass cleaner on the
instrument panel or door panels. Wipe
any glass cleaner off these surfaces
immediately.
• For windshields contaminated with
tree sap, chemicals, wax or bugs, clean
the entire windshield using steel wool
(no greater than 0000 grade) in a
circular motion and rinse with water.
• Clean the wiper blades with isopropyl
rubbing alcohol or windshield washer
concentrate.
Note: Do not use razor blades or other
sharp objects to clean or remove decals
from the inside of the heated rear window.
The vehicle warranty does not cover
damage caused to the heated rear window
grid lines.
