Under engine misfire conditions, excessive exhaust temperatures
could damage the fuel system, interior floor coverings or other
vehicle components, possibly causing a fire.
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
Refer to the Engine Operator’s Manual.
Stop engine (if equipped)
This light is used in conjunction
with the electronic engine control.
Refer to the Engine Operator’s
Manual for specific information regarding this feature.
If the engine shuts down, it can be restarted and operated for 30
seconds at a time or until the problem is corrected. Refer toEngine
shutdown systemin theDrivingchapter.
Drivers of electronically controlled engines should know the
extent of warning engine shutdown system before operating the
vehicle. This information can be obtained from your dealer.

Engine coolant temperature gauge
Indicates the temperature of the
engine coolant. At normal operating
temperature, the needle remains
within the normal area (the area
between the“H”and“C”). If it
enters the red section, the engine is
overheating. Stop the vehicle as
soon as safely possible, switch off
the engine immediately and let the
engine cool. Refer toEngine
coolantin theMaintenance and
specificationschapter.
Never remove the coolant reservoir cap while the engine is
running or hot. Steam and scalding liquid from a hot cooling
system can burn you badly.
This gauge indicates the temperature of the engine coolant, not the
coolant level. If the coolant is not at its proper level the gauge indication
will not be accurate.
Engine oil pressure gauge
Indicates engine oil pressure. At
normal operating temperature, the
needle will be in the normal range
(the area between the“L”and“H”);
if the needle goes below the normal
range, stop the vehicle as soon as
safely possible and switch off the
engine immediately. Check the oil
level. Add oil if needed (refer to
Engine oilin theMaintenance
and specificationschapter). If the oil level is correct, have your vehicle
checked at your dealership or by a qualified technician.

To prevent electrical shock, do not use your heater with
ungrounded electrical systems or two-pronged (cheater)
adapters.
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

Excessive full throttle operation below peak torque RPM will shorten
engine life to overhaul and can cause serious engine damage. Operation
of the engine below peak torque RPM can occur during gear shifting due
to difference of gear ratios.
Engine shutdown system (if equipped)
This system is designed to help prevent engine damage that could result
from operating the engine during a prolonged period of low engine oil
pressure, high engine coolant temperature or low coolant level. If any of
these conditions occur, a warning light will illuminate and a chime will
sound warning the operator that the engine will shutdown in 30 seconds.
This is to allow time for the operator to move the vehicle off the road. If
additional time is required, the engine can be restarted and run each
time for approximately 30 seconds.
Do not attempt to use this restarting feature to drive the vehicle, serious
engine damage could result.
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.

Hard steering can be caused by any of the following conditions:
•Underinflated tire(s) on any wheel(s)
•Vehicle overload
•Misalignment of the front tires
•Lack of lubricant in the front spindle bearings or linkage components
•Low oil level in the power steering system

AIR SUSPENSION SYSTEM (IF EQUIPPED)
The on-highway air suspension system is designed to provide a superior
ride, outstanding driver comfort while minimizing wear on the cab, frame
and payload.
The height control valve automatically keeps the vehicle at a constant
level due to load changes and uneven road surfaces.
Air suspension-equipped vehicles are equipped with a dryer module
which needs to be opened monthly to remove moisture from the system.

WINDSHIELD WASHER FLUID
Checking and adding washer fluid
Inspect the solution level in the
washer reservoir when insufficient
solution is sprayed.
Use 3.8L (4.0 quarts) of
Ultra—Clear Windshield Washer
Concentrate or a washer fluid that
meets the Ford specification listed.
Refer toLubricant specifications
in this chapter.
State or local regulations on volatile
organic compounds may restrict the use of methanol, a common
windshield washer antifreeze additive. Washer fluids containing
non-methanol antifreeze agents should be used only if they provide cold
weather protection without damaging the vehicle’s paint finish, wiper
blades or washer system.
Do not put engine coolant or antifreeze in the washer fluid
reservoir. Engine coolant or antifreeze can severely reduce
visibility if sprayed on the windshield.
ENGINE OIL
Checking engine oil level—Cummins B and Caterpillar 3126 B
engines
Refer to the appropriate engine operator’s manual for information on the
engine oil.
Checking engine oil level—7.3L Power Stroke engine
Refer to the general maintenance information section for the appropriate
intervals for checking the engine oil.
Check the engine oil level consistently and accurately. The following
procedure is recommended:
1. Start the engine and let it run until it reaches normal operating
temperature (the engine coolant temperature gauge indicator will be
near the center of the normal area between H and C).
2. Park the vehicle on level ground.

3. Set the parking brake and shift into N (Neutral) (automatic
transmission) or 1 (First) (manual transmission).
4. Turn off the engine and wait a few minutes for the oil to drain
completely into the oil pan.
5. Open the hood. Protect yourself from engine heat.
6. Locate and carefully remove the
engine oil level indicator (dipstick).
7. Wipe the indicator clean. Insert the indicator fully, then remove it
again.
•If the oil level isbetween FULL and OPERATING RANGE,the oil
level is acceptable.DO NOT ADD OIL.
•Maintain the oil level between ADD and OPERATING RANGE on the
dipstick by adding oil as required.
•The distance from ADD to OPERATING RANGE on the dipstick
represents 1.9L (2 quarts).
•Oil levels above OPERATING RANGE may cause engine damage. Some
oil must be removed from the engine by a qualified service technician.
8. Put the indicator back into the engine and ensure it is fully seated.
