2015 FORD F750 power steering

•At temperatures of –4°F (–20°C) or below, it is recommended that
you use a crankcase-mounted coolant heater to improve cold engine
starting.
•If operating in arctic temperatures of –20°F (–29°C) or lower, consult
your truck dealer for information about special cold weather
equipment and precautions.
Hot Weather
•Use a permanent-type engine coolant to protect the engine against
damage from overheating.
•Fill the fuel tank at the end of daily operation to prevent
condensation in the fuel system.
•Keep external surfaces of the engine, radiator, charge air cooler, air
conditioning condenser and accessories clean to avoid dirt build-up.
•You may experience above normal coolant temperatures while driving
in a transmission gear ratio that lugs the engine. To correct this
problem, increase engine speed by downshifting into the next lower
gear.
STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to decrease the driver’s effort in steering your vehicle.
To help prevent damage to the power steering pump:
•Never hold the steering wheel to the extreme right or the extreme
left for more than a few seconds when the engine is running.
•Do not operate your vehicle with the power steering pump fluid level
below the ADD mark on the MAX COLD side of the power steering
reservoir dipstick.
•Some noise is normal during operation. If the noise is excessive,
check for low power steering pump fluid level before seeking service
by an authorized dealer.
•Low power steering pump fluid levels may cause heavy or uneven
steering efforts. Check the power steering pump fluid level before
seeking service from an authorized dealer.
•Do not fill the power steering pump reservoir above the FULL mark
on the MAX HOT side of the power steering reservoir dipstick, as this
may result in leaks from the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer your vehicle manually, but it takes more effort.

provided by the service manual. Hydraulic brake systems are
power-assisted. There is a great reduction in braking capabilities
without engine assist.
•Proper fluid level. The level should be at the bottom edge of the ring
on each reservoir fill port. Do not fill the master cylinder to the top of
the reservoir. If fluid level requires attention to maintain a proper
master cylinder level, this is an indication of either severe operation
(pad wear) or fluid leakage. A more frequent and thorough brake
inspection is required.
•Brake lines, hoses and fittings. Repair or replace brake line tubes,
hoses or fittings as required. Inspect these components every
4000 miles (6000 kilometers):
•Lines for kinks, dents, corrosion or rupture.
•Hoses for abrasions, kinks, soft spots or rupture, collapse, cracks,
twists or loose frame supports. When replacing a hose, be sure
there is adequate clearance to the hose to avoid an abrasion to the
new hose.
•All connections for leaks.
Driveline Parking Brake
WARNING:Use wheel chocks and exercise caution when
inspecting under the vehicle. A vehicle roll-away could result in
property damage, personal injury or death.
A qualified technician should adjust the parking brake and keep to the
instructions in the service manual.
Steering System
WARNING:Failure to maintain the steering system in proper
condition can cause reduced steering ability resulting in property
damage, personal injury or death.
Note:Have any steering problems immediately corrected by a qualified
service technician.
Ask your service technician to examine the steering mechanism. Only
minor adjustments may be necessary. Regular inspections should include:
•Checking the tie rod, drag link end clamp bolts and ball joints for
proper tightness.
•Checking for installation and spread of cotter pins and tightness of
nuts at both ends of the tie rod and drag link.
204Maintenance

•Checking that the pitman arm (steering arm at steering gear)
mounting is tight and locked. Check system for leaks or hose chafing.
Repair immediately, if necessary.
•Maintaining proper steering gear and power steering pump lubricant
levels.
•Checking steering column joint bolts and steering linkage, particularly
for body-to-chassis clearance.
Steering Column Joint Bolts
As a good maintenance practice, check steering column joint bolt
tightness every 60000 miles (96000 kilometers) or annually, whichever
occurs first. Do not overtighten the bolts.
Hydraulic System
Whenever draining and refilling the power steering’s hydraulic system for
any reason, bleed air from the system before returning the vehicle to
service. Failure to bleed the hydraulic system properly can result in
degradation of power system performance.
Consult an authorized dealer who is aware of the proper procedures for
filling and bleeding the system.
Catalytic Converter (Diesel Engine)
Note:If your vehicle is equipped with a catalytic converter or muffler,
do not blend waste oil with diesel fuel. Operate only on ultra-low sulfur
(less than 15 parts per million sulfur) diesel fuel with a cetane value of
45 or higher.
If your diesel engine is equipped with a catalytic converter, it is
important to review the maintenance schedule to make sure proper
functioning of the catalytic converter. Also, take precautions not to
damage the catalytic converter when servicing your engine or storing
your vehicle.
Diesel Exhaust Fluid (DEF), Diesel Particulate Filter (DPF) and
Select Catalyst Reduction (SCR) System
See your engine operator’s manual for information about DEF, DPF and
SCR system service
Air Induction System
WARNING:When performing maintenance to any turbocharged
engine with engine air inlet piping disconnected, keep loose
clothing, jewelry and long hair away from the engine air inlet piping. A
turbocharger compressor air inlet protective shield should be installed
over the turbocharger air inlet to reduce the risk of personal injury or
death.

Note:If adding fluid is necessary, use only the appropriate fluid. See the
Capacities and Specificationschapter. A low fluid level may indicate a
leak in the power steering system. Inspect the power steering system
and repair the leak or see an authorized dealer or a qualified technician
for service. See theScheduled Maintenancechapter for the
recommended service intervals.
Check the fluid level when it is at ambient temperature, 20°F–80°F
(-7°C–25°C):
1. Set the parking brake, and then start the engine.
2. Shift into positionNorP(if equipped) (automatic transmission) or
first gear (manual transmission) and turn the engine off.
3. Open the hood.
4. Clean the top of the power steering fluid reservoir.
5. Remove the dipstick from the reservoir and wipe the dipstick clean.
6. Reinstall the dipstick. Remove it again and check the fluid level.
Check the MAX. COLD side of the
dipstick if the fluid is cool or warm
to the touch (approximately
68°F-120°F [20°C-49°C]). The fluid
level should be within the FULL
range. If necessary, add fluid in
small amounts, continuously
checking the level, until it reaches
the proper level.
Check the MAX. HOT side of the
dipstick if the fluid is too hot to
touch (approximately 176°F–230°F
[80°C-110°C]). The fluid level
should be within the FULL range. If
necessary, add fluid in small
amounts, continuously checking the
level, until it reaches the proper
level.
When you install the dipstick, make sure to seat it and tighten it
securely.
You can also check the fluid level by looking at the see-through plastic
reservoir. Make sure that the fluid is within the minimum and maximum
fluid range as marked on the reservoir.

To make sure that 911 Assist works properly:
•SYNC must be powered and working properly at the time of the
incident and throughout feature activation and use.
•SYNC 911 Assist feature must be set on prior to the incident.
•A Bluetooth-enabled and compatible phone has to be paired and
connected to SYNC.
•A connected Bluetooth-enabled phone must have the ability to make
and maintain an outgoing call at the time of the incident.
•A connected Bluetooth-enabled phone must have adequate network
coverage, battery power and signal strength.
•The vehicle must have battery power and be located in the United
States, Canada or in a territory in which 911 is the emergency
number.
In the Event of a Crash
Not all crashes deploy an airbag or activate the fuel pump shut-off
(which would activate 911 Assist); however, if 911 Assist is triggered,
SYNC tries to contact emergency services. If a connected phone is
damaged or loses connection to SYNC, SYNC searches for, and tries to
connect to, any available previously paired phone and tries to make the
call to 911.
Before making the call:
•SYNC provides a short window of time (about 10 seconds) to cancel
the call. Failure to cancel the call results in SYNC attempting to dial
911.
•SYNC says the following, or a similar message: “SYNC will attempt to
call 911, to cancel the call, press Cancel on your screen or press and
hold the phone button on your steering wheel.”
If the call is not cancelled and a successful call is made, a pre-recorded
message is played for the 911 operator, then the occupant(s) in the
vehicle is able to talk with the operator. Be prepared to provide your
name, phone number and location immediately, because not all 911
systems are capable of receiving this information electronically.
911 Assist May Not Work If
•Your cellular phone or 911 Assist hardware was damaged in a crash.
•The vehicle’s battery or SYNC system has no power.
