WARNING LIGHTS AND CHIMES
Air clean warning (if equipped)
Illuminates when the ignition is
turned to the ON position and the
engine is off. The light also
illuminates when the air system is
restricted (dirty, clogged).
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.
Charging system
Illuminates when the ignition is
turned to the ON position and the
engine is off. The light also
illuminates when there is no

Parking brake warning (if equipped)
Momentarily illuminates when the
ignition is turned to the ON position
and the engine is off.
If the warning lamp 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 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) durning operation, the remaining brake system is
still operational but the stopping distance will be greater.
Parking brake 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.
Also illuminates when the parking
brake is engaged.
Engine protect warning (Cummins engine only)
Illuminates when there is a fault in
the electronic subsystem but the
vehicle can be driven, and indicates
one of the following conditions:
•low oil pressure
•low coolant level
•high coolant temperature
•high intake manifold temperature

Manual heating and air conditioning system
Fan speed control
Controls the volume of air circulated
in the vehicle.
Temperature control knob
Controls the temperature of the
airflow inside the vehicle.
Mode selector control
Controls the direction of the airflow
to the inside of the vehicle.
The air conditioning compressor will operate in all modes except
(Panel) and(Floor). However, the air conditioning will only function
if the outside temperature is about 10°C (50°F) or higher.
Since the air conditioner removes considerable moisture from the air
during operation, it is normal if clear water drips on the ground under
the air conditioner drain while the system is working and even after you
have stopped the vehicle.
•MAX A/C-Uses recirculated air to cool the vehicle. MAX A/C is noisier
than A/C but more economical and will cool the inside of the vehicle
faster. Airflow will be from the instrument panel registers. This mode
can also be used to prevent undesirable odors from entering the
vehicle.
•A/C-Uses outside air to cool the vehicle. It is quieter than MAX A/C
but not as economical. Airflow will be from the instrument panel
registers.

•(Panel) -Distributes outside air through the instrument panel
registers. However, the air will not be cooled below the outside
temperature because the air conditioning does not operate in this
mode.
•OFF-Outside air is shut out and the fan will not operate. For short
periods of time only, use this mode to prevent undesirable odors from
entering the vehicle.
•
(Panel and floor) -Distributes outside air through the instrument
panel registers and the floor ducts. Heating and air conditioning
capabilities are provided in this mode. For added customer comfort,
when the temperature control knob is anywhere in between the full
hot and full cold positions, the air distributed through the floor ducts
will be slightly warmer than the air sent to the instrument panel
registers.
•
(Floor) -Allows for maximum heating by distributing outside air
through the floor ducts. However, the air will not be cooled below the
outside temperature because the air conditioning does not operate in
this mode.
•
(Floor and defrost) -Distributes outside air through the
windshield defroster ducts and the floor ducts. Heating and air
conditioning capabilities are provided in this mode. For added
customer comfort, the air distributed through the floor ducts will be
slightly warmer than the air sent to the windshield defroster ducts. If
the temperature is about 10°C (50°F) or higher, the air conditioner
will automatically dehumidify the air to reduce fogging.
•
(Defrost) -Distributes outside air through the windshield
defroster ducts. It can be used to clear ice or fog from the windshield.
If the temperature is about 10°C (50°F) or higher, the air conditioner
will automatically dehumidify the air to reduce fogging.
Operating tips
•In humid weather, select
before driving. This will reduce fogging
on your windshield. After a few minutes, select any desired position.
•To prevent humidity buildup inside the vehicle, don’t drive with the
climate control system in the OFF or MAX A/C position.
•Don’t put objects under the front seat that will interfere with the
airflow to the rear seats (if equipped).

•Remove any snow, ice or leaves
from the air intake area (at the
bottom of the windshield under
the hood).
•If your vehicle has been parked with the windows closed during hot
weather, the air conditioner will do a much faster job of cooling if you
drive for two or three minutes with the windows open. This will force
most of the hot, stale air out of the vehicle. Then operate your air
conditioner as you would normally.
•Do not place objects over the defroster outlets. These objects can
block airflow and reduce your ability to see through your windshield.
Also, avoid placing small objects on top of your instrument panel.
These objects can fall down into the defroster outlets and block
airflow and possibly damage your climate control system.
Do not place objects on top of the instrument panel, as these
objects may become projectiles in a collision or sudden stop.

RESTARTING AFTER RUNNING OUT OF FUEL
The fuel system may need to be purged of air, refer toRunning out of
fuelin theMaintenance and carechapter.
OPERATING THE ENGINE
Do not operate the engine at full throttle below peak torque engine
speed (RPM) for more than one minute at a time (peak torque RPM
varies from 1200-1500 RPM depending on engine rated speed).
Monitor the oil pressure and coolant
temperature gauges frequently.
If the gauges indicate any reading is
not in the normal operating range,
stop your vehicle as soon as
possible, shut the engine off and
check the appropriate fluid level. If
an overheating condition starts to
occur, release the throttle pressure
or shift the transmission into a
lower gear, or both, until the
temperature returns to normal operating range.
Continuous operation with low coolant
temperature, below 60°C (140°F) or
high coolant temperature 100°C
(212°F) can damage the engine.
Most failures give some kind of early
warning. Look and listen for changes
in performance, sound or engine
appearance that can indicate service
or engine repair is needed. Some
changes to look and/or listen for:
•Engine misfires
•Loss of power
•Sudden changes in engine operating temperature or oil pressure
•Excessive smoke
•Fuel, oil or coolant leaks
•Vibration
•Increased oil or fuel consumption

EXHAUST FUMES
Never idle the engine in closed areas. Never sit in a parked or
stopped vehicle for any amount of time with engine running.
If you ever smell exhaust fumes of any kind inside your vehicle,
have your dealer inspect and fix your vehicle immediately. Do
not drive if you smell exhaust fumes. These fumes are harmful and
could kill you.
In order to guard against fumes entering your vehicle, the exhaust
system and body ventilation system should be checked by a qualified
technician:
•Each time the vehicle is raised for service.
•Whenever a change in exhaust system noise is noted.
•Whenever the vehicle has been damaged by impact from another
vehicle, object or road obstruction.
In order to afford proper operation, all air inlet vents should be kept
clear of snow, leaves and other debris.
If you run the engine while stopped (idled) in an unconfined area, open
the windows at least 2.5 cm (one inch) and adjust the heating or air
conditioning to draw outside air into the vehicle as follows:
•If your vehicle has outside air control vents, open them fully.
•Set fan speed on high with function control to any position except
OFF or MAX A/C and the temperature control on any desired position.
•Adjust air control system to force outside air into the vehicle.
BACKING UP
To avoid the possibility of personal injury while backing the
vehicle, always be sure your vehicle’s path is clear.
Before backing your vehicle, be sure you can do so safely. If anything
behind the cab limits your view, do not rely on mirrors alone to assure
that your intended path is clear. If other persons are in the vicinity, have
someone standing well behind the vehicle and outside your intended
path - visible through an exterior mirror - guide you as you back up.

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.
Hydraulic brake booster system (Hydromax)
The Hydromax systems receive fluid pressure from the power steering
pump to provide power assist during braking.
The Hydromax booster receives backup pressure from the reserve
system electric pump whenever the fluid in the power steering system is
not flowing. When the engine is OFF, the pump will turn on if the brake
pedal is applied, or if the ignition is turned to the ON position.
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.

Burnish procedure
For optimal performance of a new parking brake system/new linings
perform the following procedure:
1. Make ten stops from 40 km/h (20 mph) with the parking brake lever
force set at 18kg (40 lbs).
2. While driving the vehicle at 40 km/h (20 mph) apply the parking brake
(with applicable force to set to approximately 18kg [40 lbs.]). Allow the
vehicle to come to a complete stop, release the parking brake.
3. Drive 16.8 km (1.5 miles) to cool the brakes.
4. Repeat steps 1 through 3 ten times.
AIR BRAKES (if equipped)
Foot service brakes
Air brakes are operated by a
standard dash-mounted foot pedal.
All standard equipment brakes are
designed to be self-adjusting.
Automatic adjustment, when
required, occurs whenever the
brakes are applied and released
during forward or reverse operation.
Know the required stopping
distances for all driving conditions
that may be encountered. For longer brake lining life, take full advantage
of engine braking power when coming to a stop.
Before descending a long or steep hill, shift to a lower gear and avoid
continuous application of the brakes.
Do not drive with your foot resting on the brake pedal. This will
result in abnormally high brake temperatures, excessive lining
wear and increased stopping distances.
Continuous application of the brakes will cause the brakes to
overheat, resulting in a temporary loss of braking.
Occasional or intermittent brake squeal may result from environmental
conditions such as cold, hot, wet, snow, salt, mud, etc. This condition will

When air pressure is insufficient
(below 534 kPa [60 psi]), a warning
light illuminates and a buzzer
sounds when the ignition is in the
ON position.
This condition may be caused by excessive brake applications depleting
the system air pressure. If this condition occurs, stop driving the vehicle
until the compressor has fully recharged the air system. Do not move the
vehicle in this condition because the brake system may be inoperative.
Select a gear ratio to help slow your vehicle before descending grades.
Supplement with brakes as required to safely slow the vehicle and avoid
overspeeding the engine.
Air chamber stroke indication
All Ford air chamber push rods have orange stroke indicator stripes that
alert the operator when the braking system requires adjustment or
repair. The orange stripe is painted on the air chamber push rod at the
slack adjuster readjustment stroke dimension.
Air brake inspection and adjustment should be performed by a qualified
service technician in accordance with the instructions in the Ford Truck
Service Manual.
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.
