2015 FORD F750 maintenance

Your vehicle is equipped with two or three maintenance-free batteries
mounted in a covered tray located on the left frame rail. The covered
battery tray, depending upon application, may also have one or two steps
attached.
Covered battery tray shown
(battery tray with steps
similar).Pull up on the two rubber
straps on the battery cover and
move them to the side of the
battery in order to remove the lid.

removed.
For longer, trouble-free operation, keep the top of the battery clean and
dry. Also, make sure you tightly fasten the battery cables 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.
If you plan to store your vehicle for an extended period, disconnect the
negative battery cable. This minimizes the discharge of your battery
during storage.
If the engine cranks but does not start, remove the battery box cover
and check the 40 amp inline fuse located on the battery cable above the
battery.
Because a computer electronically controls your vehicle’s engine, battery
power controls some conditions. When you disconnect the battery or
install a new battery, the engine must relearn its idle and fuel trim
strategy 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 positionP(automatic transmission) or neutral
(manual transmission), turn off all accessories and start the engine.
3. Run the engine until it reaches normal operating temperature.

4. Allow the engine to idle for at least one minute.
5. Turn on the air conditioning 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 the transmission in positionP
(automatic transmission) or neutral (manual transmission) and allow
the engine to idle for at least one minute.Note:Not allowing the
engine to relearn the idle trim may adversely affect the idle quality of
your vehicle until the engine eventually relearns the idle trim.
7. Drive your vehicle to complete the relearning process.
If you disconnect the battery or install a new battery, you have to reset
the clock and radio settings after reconnecting the battery.
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.

CHANGING THE WIPER BLADES
1. To remove the wiper blade, pull
the wiper arm away from your
vehicle. Pry open the lock cover
(A) with your thumb to release
the blade.
2. Press the retaining clip to
disengage the wiper blade, and
then pull the wiper blade down
(C) toward the windshield to
remove it from the arm.
3. To install the new wiper blade,
insert the wiper blade into the
wiper arm hook (B).
4. While holding the wiper arm,
push the wiper blade up and
away from the windshield.
5. Close the lock cover.
Replace wiper blades at least once per year for optimum performance.
Poor wiper quality can be improved by cleaning the wiper blades and the
windshield. SeeCleaning the windows and wiper bladesin theVehicle
Carechapter.
To prolong the life of the wiper blades, it is highly recommended to
scrape off the ice on the windshield before turning on the wipers. The
layer of ice has many sharp edges and can damage the micro edge of the
wiper rubber element.

ADJUSTING THE HEADLAMPS
The headlamps on your vehicle are properly aimed at the assembly plant.
If your vehicle has been in an accident, an authorized dealer should
check the alignment of your headlamps.
CHANGING A BULB
Lamp Assembly Condensation
Exterior lamps have vents 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 an authorized dealer for service if any of the above
conditions of unacceptable moisture are present.
