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 or 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 theMaintenance and Carechapter.
Safety belt
Momentarily illuminates when the
ignition is turned to the ON position
to remind you to fasten your safety
belts. For more information, refer to
theSeating and safety restraints
chapter.
Service engine soon
TheService Engine Soonindicator
light illuminates when the ignition is
first turned to the ON position to
check the bulb. If it comes on after
the engine is started, one of the
engine’s control systems may be
malfunctioning. The light may illuminate without a driveability concern
being noted. The vehicle will usually be drivable and will not require
towing.
Temporary malfunctions may cause yourService Engine Soonlight to
illuminate. Examples are:
1. The vehicle has run out of fuel. (The engine may misfire or run
poorly.)
2. Poor fuel quality or water in the fuel.

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.

These transmissions have no P (Park) position. Before leaving
the driver’s seat, always shift into N (Neutral) and set the
parking brake. Shut the engine off and remove your ignition key.
Always use wheel chocks for hilly or off-road parking. Unexpected and
possibly sudden vehicle movement may occur if these precautions are
not taken.
Gearshift positions
R (Reverse)- Use this position to
back the vehicle. Completely stop
the vehicle before shifting from R
(Reverse) to any forward gear. The
reverse warning signal will sound
when the selector is in R (Reverse).
Reverse has only one gear and
provides the greatest traction. The
Select and Monitor indicators will
display R when reverse is attained.
N (Neutral)- Use N (Neutral) for
starting the engine. If the engine
starts in any gear other than N
(Neutral), the start circuit should be
serviced immediately. Shift to N
(Neutral) and set the parking brake
any time the engine is to be running
while the operator is not at the
controls. The engine should be at
idle speed when any shift from N
(Neutral) to a drive range is made.
The Select and Monitor indicators
will display N.
Do not allow your vehicle to coast in N (Neutral). Transmission
braking is not available in N (Neutral). This practice can also
result in transmission damage.

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.

•Battery tray with cover removed.
Motorcraft maintenance-free batteries do not normally require adding
additional water. However, for severe usage or in high temperature
climates, check the battery electrolyte levels. Refer to the Scheduled
Maintenance Guide for the service interval schedules.
Keep the electrolyte level in each cell up to the “level indicator”.
Do not overfill the battery cells.
If the electrolyte level in the battery is low, you can add plain tap water
to the battery, as long as you do not use hard water (water with a high
mineral or alkali content). If possible, however, try to only fill the battery
cells with distilled water. If the battery needs water often, have the
charging system checked.
Make sure the battery cover/shield is reinstalled after the battery
has been cleaned or replaced.
For longer, trouble-free operation, keep the top of the batteries clean
and dry. Also, make certain the battery cables are always tightly fastened
to the battery terminals.
If you see any corrosion on the battery or terminals, remove the cables
from the terminals and clean with a wire brush. You can neutralize the
acid with a solution of baking soda and water.

Batteries normally produce explosive gases which can cause
personal injury. Therefore, do not allow flames, sparks or lighted
substances to come near the battery. When working near the battery,
always shield your face and protect your eyes. Always provide proper
ventilation.
When lifting a plastic-cased battery, excessive pressure on the
end walls could cause acid to flow through the vent caps,
resulting in personal injury and/or damage to the vehicle or battery.
Lift the battery with a battery carrier or with your hands on opposite
corners.
Keep batteries out of reach of children. Batteries contain sulfuric
acid. Avoid contact with skin, eyes or clothing. Shield your eyes
when working near the battery to protect against possible splashing of
acid solution. In case of acid contact with skin or eyes, flush
immediately with water for a minimum of 15 minutes and get prompt
medical attention. If acid is swallowed, call a physician immediately.
AIR FILTER
When to service
Your vehicle is equipped with an air filter restriction gauge to determine
when to replace the air filter element. It is not possible to determine the
need for service by visually inspecting the air filter.
When the yellow indicator on the air
filter restriction indicator reaches
the red line, the air filter element
should be replaced.
Each time the air filter element is
replaced, reset the air filter
restriction indicator by pressing the
red button.

10. Reset the air filter restriction indicator.
11. Inspect the air induction system for loose fitting, damaged or missing
components and repair as necessary.
WINDSHIELD WIPER BLADES
Check the wiper blades at least twice a year or when they seem less
effective. Substances such as tree sap and some hot wax treatments used
by commercial car washes reduce the effectiveness of wiper blades.
Checking the wiper blades
If the wiper blades do not wipe properly, clean both the windshield and
wiper blades using undiluted windshield wiper solution or a mild
detergent. Rinse thoroughly with clean water. To avoid damaging the
blades, do not use fuel, kerosene, paint thinner or other solvents.
Changing the wiper blades
To replace the wiper blades:
1. Pull the wiper arm away from the
windshield and lock into the service
position.
2. Turn the blade at an angle from
the wiper arm. Push the lock pin
manually to release the blade and
pull the wiper blade down toward
the windshield to remove it from the
arm.
3. Attach the new wiper to the
wiper arm and press it into place
until a click is heard.
