2015 FORD F750 Instrument

Push the palm release lever (A) on
the parking brake handle (B) and
push down as far as possible to
release the brake. Driving with the
parking brake on causes the brakes
to wear out quickly and reduces
fuel economy.
We recommend you not use the parking brake to stop a moving vehicle.
However, if the normal brakes fail, you can use the parking brake to stop
your vehicle in an emergency. Since the parking brake only applies
retardation to the rear wheels, the vehicle’s stopping distance increases
greatly and the handling of your vehicle is adversely affected.
Power Park (Hydraulic Brake Vehicles Only)
This feature uses a brake chamber mounted on the chassis to power a
spring-applied, hydraulically released driveline parking brake.
The park brake dash-mounted, yellow knob-type switch controls the
Power Park Brake. The switch has three positions: apply (out), neutral
(central), and release (in). The switch is spring-loaded to return to the
neutral (central) position after pushing or pulling it.
There is no visual indication at the knob that the parking brake
is applied or released; check the instrument cluster. If the light
is illuminated, the parking brake is applied.
Applying the Parking Brake
Pull the yellow, dash-mounted parking brake knob. The parking brake
light illuminates indicating that the parking brake has been successfully
set.
Note:If the light blinks and a warning tone sounds when you pull the
control knob, the parking brake is not functioning properly. Seek
immediate service from your dealer. SeeParking brake warning
systemin this section.
Releasing the Parking Brake
WARNING:Hold the brake pedal down while moving the
gearshift lever from position to position. If the brake pedal is not
held down, the vehicle may move unexpectedly resulting in property
damage, personal injury or death.

PRINCIPLES OF OPERATION
Cruise control lets you maintain a set speed without keeping your foot
on the accelerator pedal.
USING CRUISE CONTROL
WARNING:Do not use cruise control in heavy traffic, on
winding roads or when the road surface is slippery. This could
result in loss of vehicle control, serious injury or death.
WARNING:When you are going downhill, your vehicle speed
may increase above the set speed. The system will not apply the
brakes. Change down a gear to assist the system in maintaining the set
speed. Failure to do so could result in loss of vehicle control, serious
injury or death.
Note:Cruise control disengages if your vehicle speed decreases more
than 10 mph (16 km/h) below your set speed while driving uphill.
The cruise controls are located on
the steering wheel.
Switching On Cruise Control
Press and releaseON.
The indicator turns on in the instrument cluster.
Setting a Speed
1. Accelerate to the desired speed.
2. Press and releaseSET ACCEL.
3. Take your foot off the accelerator pedal.

UPFITTER CONTROLS (IF EQUIPPED)
The upfitter option package
provides four switches, mounted in
the center of the instrument panel.
These switches are always on
whether the engine is running or
not. Make sure you put the switches
in the off position to avoid draining
the battery when not using your
vehicle. Let the engine remain running to maintain battery charge when
using the upfitter switches for extended duration or higher current
draws. (This is even more important for vehicles with a diesel engine
since the glow plugs are also draining battery power when the ignition
key is in the on position.)
Each switch provides 10 amps of electrical battery power for a variety of
personal or commercial uses.
There is also a relay box located on the passenger side end of the
instrument panel. See your authorized dealer for service.
Switch access location is in a connector located in the engine
compartment. You can find more detailed information at
https://www.fleet.ford.com/truck/bbas/.

Quality service parts are available through an authorized dealer. If dealer
parts are not used, make sure the replacement parts are of equivalent
quality.
WARNING:The use of inferior parts can adversely affect the
quality and reliability of your vehicle which, in turn, can result in
property damage, personal injury or death.
To avoid damage to your vehicle’s electrical components before electric
welding:
•Disconnect both battery cables.
•Attach the welder ground cable as close as possible to the part being
welded.
•We recommend temporarily removing the component if welding close
to an electrical component.
Follow the checks and services in theScheduled Maintenancechapter.
Have an authorized dealer or service center inspect your vehicle at least
once a year. Remember that regular maintenance and inspections usually
prevent serious problems from developing later.
If the owner or operator of the vehicle is a skilled technician and intends
on performing the vehicle maintenance and service, he is strongly urged
to purchase a service manual.
Electrical System
Periodically inspect electrical connectors on the outside of the cab and
on the engine and frame for corrosion and tightness. Exposed terminals,
such as the fuel sender, cranking motor, alternator and feed-through
studs, should be cleaned and re-coated with a lubricant sealing grease
such as Motorcraft Silicone Brake Caliper Grease and Dielectric
Compound XG-3, or equivalent. This should include the ground cable
connector for batteries, engine and cab as well as the jump-starting stud.
Accessory Feed Connections
Vehicle electrical systems are complex and often include powertrain
components, such as engine and transmission controls, instrument panels
and ABS. While most systems operate on battery voltage (12 volts),
some systems can be as high as 90 volts or as low as five volts. See the
Electrical Circuit Diagram Manuals,available from your vehicle’s
manufacturer, to make sure that any extra body lights and accessory
connections to circuits are both appropriate and not overloaded. Do not
make modifications to any vehicle control system without first contacting
an authorized dealer.

When Fail-Safe Mode Turns On
WARNING:Never remove the coolant reservoir cap while the
engine is running or hot.
Note:Driving your vehicle without repairing the engine problem
increases the chance of engine damage. Take your vehicle to an
authorized dealer as soon as possible.
You have limited engine power when in the fail-safe mode, so drive your
vehicle with caution. Your vehicle is not able to maintain high-speed
operation and the engine runs rough. Remember that the engine is
capable of completely shutting down automatically to prevent engine
damage; therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Have your vehicle taken to an authorized dealer.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
5. Restart the engine and take your vehicle to an authorized dealer.
TRANSMISSION FLUID CHECK
Allison Automatic Transmissions
See yourAllison Automatic Transmission Operator’s Manualfor
scheduled transmission fluid checks and change intervals. Your
transmission does not consume fluid. However, you should check the
fluid level if the transmission is not working properly. For example, if the
transmission slips or shifts slowly or if you notice some sign of fluid
leakage.
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive your vehicle until it is at normal operating
temperature, approximately 20 miles (30 kilometers). Verify that the
transmission fluid temperature gauge, located on the instrument cluster,
is within the normal range.
1. Drive your vehicle 20 miles (30 kilometers) or until it reaches normal
operating temperature.
2. Park your vehicle on a level surface and engage the parking brake.
3. With the engine running, parking brake engaged and your foot on the
brake pedal, move the gearshift lever through all of the gear ranges.
Allow sufficient time for each gear to engage.
4. Latch the gearshift lever in positionNorPand leave the engine
running.
5. Remove the dipstick, wiping it clean with a clean, dry, lint-free rag.

6. Install the dipstick making sure to seat it fully in the filler tube.
7. Remove the dipstick and inspect the fluid level. The fluid should be
in the designated area for normal operating temperature or ambient
temperature.
If you must add transmission fluid, see yourAllison Automatic
Transmission Operator’s Manualfor the correct fluid type.Use of a
non-approved automatic transmission fluid may cause internal
transmission component damage.
Fluid levels above the safe range may result in transmission failure. An
overfill condition of transmission fluid may cause shift or engagement
concerns or possible damage.
