Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front
of the vehicle that could keep the airbags
from working properly?
A:Yes. If you add things that change your
vehicle’s frame, bumper system, height,
front end or side sheet metal, they may keep
the airbag system from working properly.
Also, the airbag system may not work properly
if you relocate any of the airbag sensors.
If you have any questions about this,
you should contact Customer Assistance
before you modify your vehicle. The phone
numbers and addresses for Customer
Assistance are in Step Two of theCustomer
Satisfaction Procedure on page 404.
Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out
whether this will affect my airbag system?
A:Changing or moving any parts of the
front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel,
the instrument panel, or airbag wiring can
affect the operation of the airbag system.
If you have questions, call Customer
Assistance. The phone numbers and
addresses for Customer Assistance are
in Step Two of the Customer Satisfaction
Procedure in this manual. SeeCustomer
Satisfaction Procedure on page 404.

Starter Motor Operation
•The starter motor will disengage if you release
the key or the engine reaches a predetermined
engine speed.
•To prevent overheating, the starter motor will
disengage after continuously operating for
15 seconds. You must release the key
from the start position to re-engage the starter.
•The starter motor will not engage if the engine
is already running.
•The starter motor will disengage if, after
two seconds, the starter pinion gear does not
engage the flywheel or there is no engine
rpm signal from the engine speed sensor.
Starting Your Engine
1. Without pushing the accelerator pedal, turn
your ignition key to START. When the
engine starts, let go of the key. The idle speed
will go down as your engine gets warm.2. If the engine does not start in 10 seconds,
push the accelerator pedal all the way down
and crank the engine for five more seconds,
unless it starts sooner.
3. If your engine still will not start, or starts but
then stops, it could be flooded with too much
gasoline.
Wait 15 seconds to let the starter motor cool
down. Do Steps 1 through 3 again.
When the engine starts, let go of the key and
the accelerator pedal.
Notice:Your engine is designed to work with
the electronics in your vehicle. If you add
electrical parts or accessories, you could
change the way the engine operates. Before
adding electrical equipment, check with your
dealer. If you do not, your engine might not
perform properly. Any resulting damage would
not be covered by your vehicle’s warranty.
If you ever need to have your vehicle towed, see
Towing Your Vehicle on page 241.

Airbag Readiness Light
If your vehicle has airbags, there is an airbag
readiness light on the instrument panel, which
shows the airbag symbol. The system checks the
airbag’s electrical system for malfunctions. The
light tells you if there is an electrical problem. The
system check includes the airbag sensors, the
airbag modules, the wiring, the passenger airbag
suppression circuit and the crash sensing and
diagnostic module. For more information on
the airbag system, seeAirbag System on page 68.
This light will come on
when you start your
vehicle, and it will flash
for a few seconds.
Then the light should go
out. This means the
system is ready.
If the airbag readiness light stays on after you
start the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.The airbag readiness light should flash for a few
seconds when you turn the ignition key to RUN or
START. If the light doesn’t come on then, have
it fixed so it will be ready to warn you if there is a
problem.
{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not inate in
a crash, or they could even inate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced right
away if the airbag readiness light stays on
after you start your vehicle.

Cassette Tape Messages
ERR (Error):If the player detects a tight or
broken tape, this message appears on the display
and the player ejects the tape. The radio goes
back to playing the last station selected.
CLN (Clean):If this message appears on the
display, the cassette tape player needs to
be cleaned. It still plays tapes, but it should be
cleaned as soon as possible to prevent damage to
the tapes and player. SeeCare of the Cassette
Tape Player on page 202.
If the cassette is not playing correctly, for any
other reason, try a known good cassette.
If any error occurs repeatedly or if an error cannot
be corrected, contact your dealer. If the radio
displays an error message, write it down and
provide it to your dealer when reporting the
problem.
CD Adapter Kits

Fuel Filter Replacement
If you want to change the diesel engine fuel filter
yourself, here is how to do it:
{CAUTION:
Diesel fuel is ammable. It could start a
re if something ignites it, and you could
be burned. Do not let it get on hot engine
parts, and keep matches or other ignition
sources away.
First, drain any water from the filter by following
the water draining procedure earlier in this section.
Your vehicle’s engine should be off until the end
of this procedure.
If your vehicle has the 6.6L engine, the fuel filter is
located in the engine compartment on the
driver’s side of the vehicle. If your vehicle has
either the 7.2L or 7.8L engine, the fuel filters are
located in the engine compartment on the
driver’s side of the vehicle, and on the driver’s
side frame rail in front of the fuel tank.
1. Apply the parking brake.2. Unplug the water
sensor wire
connected to the fuel
filter and unscrew
the filter element.
3. Remove the filter element. If there is any dirt
on the filter sealing surface, clean it off.
Remove and reuse the water sensor float
switch located on the bottom of the fuel filter.
4. Install the new filter element.
5. Reinstall and tighten the filter container and
reconnect the water sensor wire to the filter.
6. Use the fuel filter priming procedure earlier in
this section to prime the fuel filter.
7. Tighten the air bleed valve by turning it
clockwise until hand-tight.
8. Start your engine and let it idle for
five minutes. Check your fuel filter and air
bleed valve for leaks.

(28)= Inspect Electronic Vacuum Regulator
Valve (EVRV) filter for excessive contamination
or plugging. If needed, clean filter with solution
of soap and water, let dry and install.
(29)= Drain, flush, and refill cooling system.
This service can be complex; you should
have your dealer perform this service. See
Part C: Recommended Fluids and Lubricants
on page 397for what to use. Inspect hoses.
Clean radiator, condenser, pressure cap, and
neck. Pressure test cooling system and pressure
cap. For Caterpillar
®diesel engines, always
refer to the Caterpillar®Diesel Engine Operation &
Maintenance Manual for coolant recommendations
and change intervals.
(30)= Change the lubricant. See
Part C: Recommended Fluids and
Lubricants on page 397.
(31)= Front axle service: Re-pack upper
kingpin roller bearing.(32)= Air brake service:
•Inspect brake lines and hoses for proper
hook-up, binding, leaks, cracks, chafing,
etc. Inspect drum brake linings for wear or
cracks. Inspect other brake parts at each
wheel, including drums and wheel speed
sensor wiring. Check brake pedal for
excessive free play or travel (or every
6 months, whichever occurs first) and have
serviced if needed. Check brakes more often
if driving habits and conditions result in
frequent braking. Replace air dryer cartridge
only if excessive oil or moisture is present.
A small amount of oil in the system is normal
and should not be considered as a reason
to replace the cartridge.
•Test air lines for leaks; tighten as needed.
Replace compressor filter.
•Inspect air parking brake chamber for leaks
and damage. Inspect lines and hoses for
leaks, cracks, chafing, etc. Also check
all attachments for tightness, wear, or damage.
Note: The spring brake section of the rear
brake diaphragms are non-serviceable.
