Ford Taurus (2018 year). Manual — part 63

After battery replacement, or in some
cases after charging the battery with an
external charger, the battery management
system requires eight hours of vehicle sleep
time to relearn the battery state of charge.
During this time your vehicle must remain
fully locked with the ignition switched off.

Note:

Prior to relearning the battery state

of charge, the battery management system
may temporarily disable some electrical
systems.

Electrical Accessory Installation

To make sure the battery management
system works correctly, do not connect an
electrical device ground connection
directly to the battery negative post. This
can cause inaccurate measurements of
the battery condition and potential
incorrect system operation.

Note:

If you add electrical accessories or

components to the vehicle, it may adversely
affect battery performance and durability.
This may also affect the performance of
other electrical systems in the vehicle.

CHECKING THE WIPER
BLADES

E142463

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

Replace the wiper blades at least annually
for optimum performance.

You can improve poor wiper quality by
cleaning the wiper blades and the
windshield. See Cleaning the Windows
and Wiper Blades

(page 263).

ADJUSTING THE HEADLAMPS

Vertical Aim Adjustment

The headlamps on your vehicle are
properly aimed at the assembly plant. If
your vehicle has been in an accident, have
the alignment of your headlamps checked
by your authorized dealer.

Vertical Aim Adjustment

1.

Park the vehicle directly in front of a
wall or screen on a level surface,
approximately 25 feet (7.6 meters)
away.

2. Measure the height from the center of

your headlamp (indicated by a 3.0
millimeter circle on the lens) to the
ground and mark an 8 foot (2.4 meter)
horizontal reference line on the vertical
wall or screen at this height (a piece of
masking tape works well).

Note:

To see a clearer light pattern for

adjusting, you may want to block the light
from one headlamp while adjusting the
other.

3. Turn on the low beam headlamps to

illuminate the wall or screen and open
the hood. Cover one of the headlamps
so no light hits the wall.

E142465

4. There is a distinct cut-off (change from

light to dark) in the left portion of the
beam pattern. Position the top edge of
this cut-off 2 inches (5 centimeters)
below the horizontal reference line.

E167359

5. Locate the vertical adjuster on each

headlamp. Use a Phillips #2
screwdriver to turn the adjuster either
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. Repeat Steps 3 through 7 to adjust the

other headlamp.

7.

Close the hood and turn off the lamps.

Horizontal Aim Adjustment

Horizontal aim is not required for this
vehicle and is not adjustable.
