Brake
Dust Caution
Caution: Avoid taking the following actions when
you service wheel brake parts:
.. Do not grind brake linings.
• Do not sand brake linings.
• Do not clean wheel brake parts with a dry
brush or with compressedair.
Some
models or aftermarket brake parts may
contain asbestos fibers which can become
airborne in dust. Breathing dust with asbestos
fibers may cause serious bodily harm. Use a
water-dampened cloth in
order to remove any dust
on brake parts. Equipment is available
commercially in order to perform this washing
function. These wet methods
prevent fibers from
becoming airborne.
Brake Fluid Irritant Caution
Caution: Brake fluid may irritate eyes and skin. In
case
of contact, take the following actions:
" Eye contact-rinse thoroughly with water.
• Skin contact-wash with soap and water.
• If ingested-consult a physician immediately.
Brake Pipe Replacement Caution
Caution: Always use double-walled steel brake
pipe when replacing brake pipes. The use of any
other pipe is not recommended and may cause
brake
system failure. Carefully route and retain
replacement brake pipes.
Always use the correct
fasteners and in the original location for
replacement brake pipes. Failure to properly route
and retain brake pipes may cause damage to.
the brake pipes and brake system resulting
in
personal injury.
Breathing R-134a Caution
Caution: Avoid breathing the A/C Refrigerant 134a
(R-134a) and the lubricant vapor or the mist.
Exposure
may irritate the eyes, nose, and throat.
Work
in a well ventilated area. In order to remove
R-134a from the A/C system, use service
equipment that is certified to meet the
requirements
of SAE J 2210 (R-134a recycling
equipment). If an accidental system discharge
occurs, ventilate the
work area·before continuing
service. Additional health and safetyinformation
may be obtained from the refrigerant and lubricant
manufacturers.
Clutch Dust Caution
Caution: When servicing clutch parts, do not
create dust by grinding or sanding the clutch disc
or by cleaning parts with a dry brush or with
compressed air. A water-dampened cloth-NOT
SOAKED---should be used. The clutch disc
contains asbestos fibers which can become
airborne if dust·is created during servicing.
Breathing dust containing asbestos fibers may
cause serious bodily harm.
Preface
Electric Coolant Fan Caution
Caution: An electric fan under the hood can start (
up even when the engine is not running and
can injure you. Keep hands, clothing and tools
away from
any underhood electric fan.
Express Window Down Caution
Caution: Disconnect the power window switch
when working inside the driver's door. When
operated, the Express Down Feature
allows the
door window to drop very quickly, without
stopping, which could cause personal injury.
Fuel and EVAP Pipe Caution
Caution: In order to reduce the risk of fire and
personal
injury observe the following items:
.. Replace all nylon fuel pipes that are nicked,
scratched or damaged during installation,
do not attempt to repair the sections of
the nylon fuel pipes
• Do
not hammer directly on the fuel harness
body clips when installing new fuel pipes.
Damage to the nylon pipes
may result in
a fuel leak.
" Always cover nylon vapor pipes with a wet
towel before using a torch near them. Also,
neverexpose the vehicle to temperatures (
higher than 1.15°C (239°F) for more.than
one hour,
or more than .. 90°C (194°F) for any
extended period.
"
Apply a few drops of clean engine oil to the
male pipe ends before connecting fuel pipe
fittings. This will ensure proper reconnection
andprevent a possible fuel leak. (During
normal operation, the 0-rings located in the
female connector will swell and may prevent
proper reconnection if.not lubricated.)
Fuel Gauge Leak Caution
Caution: Wrap a shop towel around the fuel
pressure connection in
order to. reduce the risk of
fire andpersonal injury. The towel will absorb
any fuel leakage that occurs during the connection
of the fuel pressure gauge. Place the towel in an
approved container
1111hen the connection of
the fuel pressure gauge is complete.
Fuel Pipe Fitting Caution
Caution: Always apply a few drops of clean engine
oil to the male pipe ends before connecting fuel

fluid
and steam under pressure if radiatorcap
or surge tank cap is removed while the engine and
radiator are still hot.
Relieving Fuel Pressure Caution
Caution: ReHeve the fuel system pressure before
servicing fuel system components
in order to
reduce the
risk of fire and personal injury.
After relieving the system pressure, a
small
amount of fuel may be released when servicing
the fuel lines
or connections. In order to redLf.Ce the
chance
of personal injury, cover the regulator
and the fuel line fittings with a shop towel before
disconnecting. This
will catch any fuel that .
may leak out. Place the towel in an approved
container when the disconnection is complete.

Preface
Work Stall Test Caution
Caution: One or more of the following guidelines
may
apply when performing specific requiredtests
in the
work stall:
• When a test requires spinning the drive
wheels with the vehicle
jacked up, adhere to
the following precautions:
-Do
not exceed 56 km/h (35 mph) when
spinning one drive wheel with the
other drive wheel stopped. This .limit ;s
necessary because the speedometer
indicates
only one-half the actual vehicle
speed underthese conditions. Personal
injury may result from excessive
wheel spinning.
--' If all of the drive wheels are spinning at
the same speed, do not exceed 112 km/h
(70 mph). Personal
injury may result
from excessive wheel spinning.
- All persons should stay clear of the
rotating components
and the balance
weight areas in order to avoid possible
personal injury.
-When running an engine in the repair stall
for an extended period of time, use care
not to overheat the engine and the
transmission.
• When a test requires jacking up the vehicle
and
running with the wheels and brake
rotors removed, adhere to the
following
precautions:
-Support the suspension
of all drive
wheels
at normal ride height.
-Do
not apply the brake with the brake
rotors removed.
-Do
not place the transmission in PARK
with the drive wheels still spinning.
-Tum
Off the ignition in order to stop the
powertrain components from spinning.
Air in the Power Steering System Notice
Notice: If the power steering system has been
serviced, an accurate fluid level reading cannot
be
obtained unless air is bled from the steering system.
The air
in the fluid may cause pump cavitation
noise and may cause pump damage over a period
of time.
Anti-Corrosion Materials Notice
Notice: Anti-corrosion compounds have been applied
to the interior surfaces of some metal panels to
provide rust resistance.
W.hen servicing these panels
in areas on which this material has been disturbed,
or when installing new panels, avoid corrosion damage
by coating with anti-corrosion compound.

Preface
Belt Dressing Notice
Notice: Do not use belt dressing on the drive belt.
Belt dressing causes the breakdown of the composition
of the drive belt. Failure to follow this recommendation
will damage the drive belt.
Component Fastener Tightening Notice
Notice: Replacement components must be the correct
part number for the application. Components
requiring the use of the thread locking compound,
lubricants, corrosion inhibitors, or sealants are
identified in the service procedure. Some replacement
components may come with these coatings already
applied. Do not use these coatings on components
unless specified. These coatings
can affect the
final torque, which may affect the operation of the
component. Use the correct torque specification when
installing components in order to avoid damage.
Defective Scan Tool Notice
Notice: Do not use a scan tool that displays faulty
data. Report the scan tool problem to the
manufacturer. Use of a faulty scan tool can result in
misdiagnosis and unnecessary parts replacement.
Engine Emission Notice
Notice: Modifications made to the engine or its
individual components can effect the vehicle's
emission controls and may cause the Malfunction
Indicator Lamp (MIL), Check Engine, or Service Engine
Soon lamp to illuminate. Modifications may also
cause the
vehicl.e to fail a required Emission
Inspection/Maintenance test.
Fastener Notice
Notice: Use the correct fastener in the correct
location. Replacement fasteners must be the correct
part number for that application. Fasteners requiring
replacement or fasteners requiring the use of '
thread locking compound or sealant are identified in
the service procedure. Do not use paints, lubricants, or
corrosion inhibitors
on fasteners or fastener joint
surfaces unless specified. These coatings affect
fastener torque and joint clamping force and may
damage the fastener. Use the correct tightening
sequence and specifications when installing fasteners
in order to avoid damage to parts and systems. -
Fuel Pressure Notice
Notice: Do not allow the fuel pressure to exceed the
specified value because damage to the fuel pressure
regulator or the fuel pressure gauge may result.
Fuel Tank: Strap Fastener Notice
Notice:Tighten the strap fasteners by steps,
alternating between the fasteners, until the specified
torque is reached. A failure to tighten th.e strap
fasteners as specified will cause the bottom of the
tank to flex upward. This will result in the fuel gauge
indicating that there is fuel remaining
in the tank when
the tank runs dry.
Cautions and Notices - 7
Handling ESD
Sensitive Parts Notice
Notice: Electrostatic discharge (ESD) can da,,age
many solid-state electri.cal components. ESD
susceptible components may
or may not be l~beled
with the ESD symbol. Handle all electrical cornponents
carefully. Use the following precautions in ord6r to
avoid ESD damage:
" Touch a metal ground point in order to renove
your body's static charge before servicingany
electronic component; especially after slidhg
across the vehicle seat.
• Do not touch1exposed terminals. Terminah may
connectto circuits susceptible the ESD danage.
O Do not allow tools to contact exposed
terminals when servicing connectors.
• Do not remove components from their proective
packaging until required to do so.
• Avoid the following actions unless requirecby the
diagnostic procedure:
-Jumpering or grounding of the compcients
or connectors.
-Connecting test equipment probes to
components or connectors. Connect
the ground lead first when using test robes.
• Ground the protective packaging of any
component before opening. Do not rest soli-state
components on metal workbenches, or on Ip
of TVs, radios, or other electrical devices.
Handling IAC Valve Notice
Notice: If the IAC valve has been in service: D(f\lOT
push or pull on the IAC valve pintle. The force
required to move the pintle
may damage the thnds
on the worm drive. Also, DO NOT soak the IAC
valve in any liquid cleaner or solvent, as damag1naY
result.
Heated Oxygen and Oxygen Sensor
Notice
Notice: Do not remove this pigtailfrom either the
heated oxygen sensor (H02S) or the oxygen
sensor
(028). Removing the pigtail or the conne~
will affect sensor operation.
Handle the oxygen sensor carefully.
Do not dropl
H02S. Keep the in-line electrical conne9tor and
the louvered end free of grease, dirt, or other
contaminants. Do not use cleaning solvents of
any type.
Do not repair the wiring, connector or terminals.
Replace the oxygen sensor if the pigtail wiring,
connector, or terminal is damaged.
This external clean air reference is obtained by w,1
the oxygen sensor signal and heater wires. Any
attempt to repair the wires, connectors, or termina
could result
in the obstruction of the air reference I
degraded sensor performance.

8 - Cautions and Notices
The following guidelines should be used when
servicing the heated oxygen sensor:
" Do not apply contact cleaner or other materials to
the sensor or vehicle harness connectors. These
materials may get into the sensor causing
poor performance. ·
" Do not damage the sensor pigtail and harness
wires in such a way that the wires inside are
exposed. This could provide a path for foreign
materials to enter the sensor and cause
performance problems.
" Ensure the sensor or vehicle lead wires should
not be bent sharply or kinked. Sharp bends or
kinks could block the reference air path through
the lead wire.
• Do not remove or defeat the oxygen sensor
ground wire (where applicable). Vehicles
that utilize the ground wired sensor may rely on
this ground as the only ground contact to the
sensor. Removal of the ground wire will cause
poor engine performance.
• Ensure that the peripheral seal remains intact on
the vehicle harness connector in order to prevent
damage due to water intrusion. The engine
harness
may. be repaired using Packard's Crimp
and Splice Seals Terminal Repair Kit. Under
no circumstances should repairs be soldered since
this could result in the air reference being
obstructed.
Ignition OFF When Disconnecting Battery
Notice
Notice: Always turn the ignition OFF when connecting
or disconnecting battery cables, battery chargers, or
jumper cables. Failing to do so may damage the
Powertrain Control Module (PCM) or other electronic
components.
Installing Hoses without Twists or Bends
Notice
Notice: The inlet and outlet hoses must not be twisted
during installation. Do not bend or distort the inlet or
outlet hoses to make installation easier. Failure to
follow these procedures could result in component
damage.
Nylon Fuel Lines Notice
Notice: Do not attempt to straighten any kinked nylon
fuel lines. Replace any kinked nylon fuel feed or
return pipes in order to prevent damage to the vehicle.
OBDII System Description Notice
Notice: The OBD II symbol is used on the circuit

Preface
PCM and ESD Notice
Notice: Do not touch the connector pins or soldered
components on the circuit board in order to prevent
possible electrostatic discharge (ESD) damage
to the PCM.
Servicing and Replacing Seat Belts Notice
Notice: To prevent possible seat belt damage, refer
to the following items before servicing or replacing lap
and shoulder belts, including single loop belt
systems: ·
"
Lap and shoulder belts will be serviced as follows:
-Replace only the part in question.
-All belts need to be serviced as a set to
assure the belt components are from
the same supplier.
- Do not intermix standard and deluxe belts on
front or rear seats.
-All attachment hardware must be replaced,
not reused.
• Keep sharp edges and damaging objects away
from belts.
• Avoid bending or damaging any portion of the belt
buckle or latch plate.
" Do not bleach or dye belt or strap webbing. Clean
with a mild soap solution and water.
" When installing lap or shoulder belt anchor bolts,
start the bolts by hand to ensure that the bolts
are threaded straight.
•
Do not attempt repairs on lap or shoulder belt
retractor mechanisms to lap belt retractor
covers. Replace defective assemblies with new
service replacement parts.
•
Do not attempt to remove the seat belt retractor
cover. The cover and the long rivet securing
the cover to the retractor are not available
as service replacement parts.
Test Probe Notice
Notice: Do not insert test equipment probes into any
connector or fuse block terminal. The diameter of
the test probes will deform most terminals. A deformed
terminal can cause a poor connection, which can
result
in system failures. Always use the J 35616-A
Connector Test Adapter Kit or the J 42675 Flat
Wire Probe Adapter Kit in order to frontprobe
terminals.
Do not use paper clips or other substitutes
as they can damage terminals and cause incorrect
measurements.
Using Proper Power Steering Fluid Notice
Notice: When adding fluid or making a complete
fluid change, always use the proper power steering
fluid. Failure to use the proper fluid will cause
hose and seal damage and fluid leaks.
