ABS FORD F650 2003 10.G Owners Manual

Brake reserve system warning (if equipped)
Illuminates to indicate normal
Hydromax booster reserve system
activation when the engine is OFF
and the service brake pedal is
applied, or when the ignition is in
the ON or START position.
This light may also illuminate momentarily if the engine is running and
the driver turns the steering wheel fully in one direction while braking.
If the light remains on while the engine is running, this indicates
inadequate hydraulic booster pressure or reserve pump system failure.
Stop the vehicle safely as soon as possible and seek service immediately.
Brake system warning
Momentarily illuminates when the
ignition is turned to the ON position
and the engine is off. If the brake
warning lamp does not illuminate at
this time seek service immediately.
If equipped with a hydraulic brake system and the warning lamp remains
illuminated after engine start up, this indicates a brake system
malfunction. Stop the vehicle safely as soon as possible and seek service
immediately.
If equipped with an air brake system, the warning light stays on until the
air pressure builds up to 414 kPa (60 psi). If the air pressure drops
below 414 kPa (60 psi) during operation, the remaining brake system is
still operational but the stopping distance will be greater.
Anti-lock brake system (ABS)
Momentarily illuminates when the
ignition is turned to the ON position
and the engine is off. If the light
remains on after the vehicle is
started, continues to flash or fails to
illuminate, have the system serviced immediately. With the ABS light on,
the anti-lock brake system is disabled and normal braking is still effective
unless the brake warning light also remains illuminated.

Trailer ABS brake system (if equipped)
Illuminates briefly when the engine
is powered-up and only when a PLC
trailer or a PLC diagnostic tool is
connected. If the light remains on
after the vehicle is started,
continues to flash or fails to illuminate, have the system serviced
immediately.
Parking brake warning (Hydraulic brakes only)
Momentarily illuminates when the
ignition is turned to the ON position
and the engine is off. Also
illuminates when the parking brake
is engaged. If the brake warning
lamp does not illuminate at these
times, seek service immediately.
Safety belt
Illuminates to remind you to fasten
your safety belts. For more
information, refer to theSeating
and safety restraintschapter.
Check trans (Allison automatic transmission)
The lamp will illuminate for several
seconds after the ignition is turned
to the ON position. Illumination of
this light indicates that a problem
has been detected and shifting may be restricted. Depending upon the
severity of the problem, the read-out digit on the shifter display may be
blank. Operation may continue in order to reach service assistance. The
ECU may not respond to shift selector requests, since operating
limitations are being placed on the transmission, i.e. upshifts and
downshifts may be restricted. Direction changes will not occur.
Refer to the Transmission Operator’s Manual for more information.

The sound of the pump operating may be heard by the driver, but this is
a normal characteristic of the system.
The reserve system provides reduced braking power, so the vehicle
should be operated under these conditions with caution, and only to seek
service repair and remove the vehicle from the roadway.
For Hydromax under normal operating conditions noise of the fluid
flowing through the booster may be heard whenever the brake is applied.
This condition is normal. Vehicle service is not required.
If braking performance or pedal response becomes very poor, even when
the pedal is strongly applied, this may indicate the presence of air in the
hydraulic system or fluid leakage. Stop the vehicle safely as soon as
possible and seek service immediately.
If the red BRAKE warning lamp in
the instrument cluster remains
illuminated after engine start up,
this indicates a system failure in the
master cylinder of the brake system. Stop the vehicle safely as soon as
possible and seek service immediately.
If the yellow BRAKE RESERVE
(E-motor) warning light remains on
while the engine is running, this
indicates inadequate hydraulic
booster pressure or reserve pump
system failure. Stop the vehicle safely as soon as possible and seek
service immediately.
Four-wheel anti-lock brake system (ABS)
A noise from the hydraulic pump motor and pulsation in the pedal may
be observed during ABS braking events. Pedal pulsation coupled with
noise while braking under panic conditions or on loose gravel, bumps,
wet or snowy roads is normal and indicates proper functioning of the
vehicle’s anti-lock brake system. If the vehicle has continuous vibration
or shudder in the steering wheel while braking, the vehicle should be
inspected by a qualified service technician.

The ABS operates by detecting the
onset of wheel lockup during brake
applications and compensating for
this tendency. The wheels are
prevented from locking even when
the brakes are firmly applied. The
accompanying illustration depicts
the advantage of an ABS equipped
vehicle (on bottom) to a non-ABS
equipped vehicle (on top) during hard braking with loss of front braking
traction.
ABS warning lamp
The
ABSwarning lamp in the instrument cluster momentarily illuminates
when the ignition is turned on and the engine is off. If the light does not
illuminate momentarily at start up, remains on after the vehicle reaches
10 to 15 km/h (5 to 10 mph), or continues to flash, the ABS needs to be
serviced.
With the ABS light on, the anti-lock brake system is disabled and normal
braking is still effective unless the brake warning light also remains
illuminated. (If your parking brake warning lamp illuminates, have your
vehicle serviced immediately).
Using ABS
•In an emergency or when maximum efficiency from the ABS is
required, apply continuous full force on the brake. The ABS will be
activated immediately, thus allowing you to retain full steering control
of your vehicle and, providing there is sufficient space, will enable you
to avoid obstacles and bring the vehicle to a controlled stop.
•The Anti-Lock system does not decrease the time necessary to apply
the brakes or always reduce stopping distance. Always leave enough
room between your vehicle and the vehicle in front of you to stop.
•We recommend that you familiarize yourself with this braking
technique. However, avoid taking any unnecessary risks.

Cam brakes—automatic slack adjusters
Standard air brakes (cam) are
equipped with automatic brake
adjusters. Automatic adjustment
occurs during forward and reverse
brake applications. Inspect brakes
for proper adjustment at the
intervals listed in the vehicle Service
Maintenance Guide.
Emergency air brake
All vehicles are equipped with a dual brake system. In the unlikely event
of a failure of one system, the second system will function for emergency
stopping. These systems are all controlled by the brake pedal in the
same manner as for normal stops.
Do not continue to operate the vehicle with a failure of one of
the systems. Take the vehicle to your dealer for service
immediately.
Anti-lock braking system (if equipped)
For information on the anti-lock braking system (ABS), refer to
Hydraulic brakesin this chapter.
Driving with ABS
Maintain a steady brake pedal application; you do not need to pump or
remove your foot from the pedal. The ABS keeps the wheels rolling
during braking to maintain control and reduce stopping distances. For
information on the anti-lock braking system (ABS), refer toHydraulic
brakesin this chapter.

excessive or prolonged breathing of fuel vapor can cause serious
illness and permanent injury.
•Avoid getting fuel liquid in your eyes. If fuel is splashed in the eyes,
remove contact lenses (if worn), flush with water for 15 minutes and
seek medical attention. Failure to seek proper medical attention could
lead to permanent injury.
•Fuels can also be harmful if absorbed through the skin. If fuel is
splashed on the skin and/or clothing, promptly remove contaminated
clothing and wash skin thoroughly with soap and water. Repeated or
prolonged skin contact with fuel liquid or vapor causes skin irritation.
If you must replace the fuel filler cap, replace it with a genuine
Ford or Motorcraft part. The customer warranty may be void for
any damage to the fuel tank or fuel system if a genuine Ford or
Motorcraft fuel filler cap is not used.
If you do not use the proper fuel filler cap, excessive pressure or
vacuum in the fuel tank may damage the fuel system or cause
the fuel system to work improperly in a collision, which may result in
possible personal injury.
Choosing the right fuel
At operating temperatures below 0°C (32°F), use a blend of No. 1D and
No. 2D Diesel fuels, also known as winterized No. 2D.
Do not use diesel fuel blended with waste oil in engines equipped with a
catalytic converter-muffler. Blending waste oil in with the fuel will plug
the catalytic converter-muffler, resulting in a significant loss of engine
power. Your emissions warranty will be voided if blending waste oil with
diesel fuel is practiced.
Use low sulfur (less than 0.05% by weight) fuel as required by the EPA
for emission compliance.
Do not mix diesel fuel with gasoline, gasohol or alcohol. This
could cause an explosion resulting in personal injury.
Do not use starting fluid such as ether or gasoline. Such fluids
can cause immediate explosive damage to the engine and
possible personal injury.
