Installing The Rear Wiper

1. Lift the rear wiper arm pivot cap away from
the glass to allow the rear wiper blade to be
raised off of the glass.

NOTE:The rear wiper arm cannot be fully raised off the
glass unless the wiper arm pivot cap is unsnapped
first. Attempting to fully raise the rear wiper arm
without unsnapping the wiper arm pivot cap may
damage the vehicle.
2. Lift the rear wiper arm fully off the glass.
3. Insert the wiper blade pivot pin into the opening on the end of the wiper arm. Grab the
bottom end of the wiper arm with one hand,
and press the wiper blade flush with the wiper
arm until it snaps into place.
4. Lower the wiper blade onto the glass and snap the wiper arm pivot cap back into place.
EXHAUST SYSTEM
The best protection against carbon monoxide entry
into the vehicle body is a properly maintained
engine exhaust system.
If you notice a change in the sound of the exhaust
system; or if the exhaust fumes can be detected
inside the vehicle; or when the underside or rear of
the vehicle is damaged; have an authorized
technician inspect the complete exhaust system
and adjacent body areas for broken, damaged,
deteriorated, or mispositioned parts. Open seams
or loose connections could permit exhaust fumes
to seep into the passenger compartment. In
addition, have the exhaust system inspected each
time the vehicle is raised for lubrication or oil
change. Replace as required.
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you uncon -
scious and can eventually poison you. To
avoid breathing CO,
Úpage 241 for further
information.
A hot exhaust system can start a fire if you
park over materials that can burn, such as
grass or leaves, and those items come into
contact with your exhaust system. Do not park
or operate your vehicle in areas where your
exhaust system can contact anything that can
burn.
CAUTION!
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will
destroy the effectiveness of the catalyst as an
emissions control device and may seriously
reduce engine performance and cause
serious damage to the engine.
Damage to the catalytic converter can result if
your vehicle is not kept in proper operating
condition. In the event of engine malfunction,
particularly involving engine misfire or other
apparent loss of performance, have your
vehicle serviced promptly. Continued opera -
tion of your vehicle with a severe malfunction
could cause the converter to overheat,
resulting in possible damage to the converter
and vehicle.
WARNING!

286SERVICING AND MAINTENANCE
Under normal operating conditions, the catalytic
converter will not require maintenance. However, it
is important to keep the engine properly tuned to
ensure proper catalyst operation and prevent
possible catalyst damage.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being
assessed against you.
In unusual situations involving grossly
malfunctioning engine operation, a scorching odor
may suggest severe and abnormal catalyst
overheating. If this occurs, stop the vehicle, turn off
the engine and allow it to cool. Service, including a
tune-up to the manufacturer specifications, should
be obtained immediately.
To minimize the possibility of catalytic converter
damage:
Do not interrupt the ignition when the transmis -
sion is in gear and the vehicle is in motion.
Do not try to start the vehicle by pushing or
towing the vehicle.
Do not idle the engine with any ignition compo -
nents disconnected or removed, such as when
diagnostic testing, or for prolonged periods
during very rough idle or malfunctioning oper -
ating conditions.
COOLING SYSTEM
Engine Coolant Checks
Check the engine coolant (antifreeze) protection
every 12 months (before the onset of freezing
weather, where applicable). If the engine coolant is
dirty, the system should be drained, flushed, and
refilled with fresh Organic Additive Technology
(OAT) coolant (conforming to MS.90032) by an authorized dealer. Check the front of the A/C
condenser for any accumulation of bugs, leaves,
etc. If dirty, clean by gently spraying water from a
garden hose vertically down the face of the
condenser.
Check the engine cooling system hoses for brittle
rubber, cracking, tears, cuts, and tightness of the
connection at the coolant recovery bottle and
radiator. Inspect the entire system for leaks. DO
NOT REMOVE THE COOLANT PRESSURE CAP
WHEN THE COOLING SYSTEM IS HOT.
Cooling System — Drain, Flush And Refill
NOTE:Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly
could lead to severe internal engine damage. If any
coolant is needed to be added to the system
please contact an authorized dealer.
If the engine coolant (antifreeze) is dirty
or contains visible sediment, have an authorized
dealer clean and flush with Organic Additive
Technology (OAT) coolant (conforming to
MS.90032).
For the proper maintenance intervals
Úpage 272.
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from your
radiator. If you see or hear steam coming from
under the hood, do not open the hood until the
radiator has had time to cool. Never open a
cooling system pressure cap when the radi
-
ator or coolant bottle is hot.
Keep hands, tools, clothing, and jewelry away
from the radiator cooling fan when the hood is
raised. The fan starts automatically and may
start at any time, whether the engine is
running or not.
When working near the radiator cooling fan,
disconnect the fan motor lead or turn the igni -
tion to the OFF mode. The fan is temperature
controlled and can start at any time the igni -
tion is in the ON mode.

288SERVICING AND MAINTENANCE
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
engine coolant (antifreeze), and to ensure that
engine coolant will return to the radiator from the
coolant expansion bottle/recovery tank (if
equipped).
The cap should be inspected and cleaned if there
is any accumulation of foreign material on the
sealing surfaces.
Disposal Of Used Coolant
Used ethylene glycol-based coolant (antifreeze) is
a regulated substance requiring proper disposal.
Check with your local authorities to determine the
disposal rules for your community. To prevent
ingestion by animals or children, do not store
ethylene glycol-based coolant in open containers
or allow it to remain in puddles on the ground. If
ingested by a child or pet, seek emergency
assistance immediately. Clean up any ground spills
immediately.
Coolant Level
The coolant expansion bottle provides a quick
visual method for determining that the coolant
level is adequate. With the engine off and cold, the
level of the coolant (antifreeze) in the bottle should
be between the “MAX” and “MIN” lines marked on
the bottle.
As long as the engine operating temperature is
satisfactory, the coolant bottle need only be
checked once a month.
When additional coolant is needed to maintain the
proper level, it should be added to the coolant
bottle. Do not overfill.
See an authorized dealer for service.
Cooling System Notes
NOTE:When the vehicle is stopped after a few miles/kilo -
meters of operation, you may observe vapor
coming from the front of the engine compartment.
This is normally a result of moisture from rain,
snow, or high humidity accumulating on the
radiator and being vaporized when the thermostat
opens, allowing hot engine coolant (antifreeze) to
enter the radiator.
If an examination of your engine compartment
shows no evidence of radiator or hose leaks, the
vehicle may be safely driven. The vapor will soon
dissipate.
Do not overfill the coolant expansion bottle.
Check the coolant freeze point in the radiator
and in the coolant expansion bottle. If engine
coolant needs to be added, the contents of the
coolant expansion bottle must also be protected
against freezing.
If frequent engine coolant additions are
required, the cooling system should be pressure
tested for leaks.
Maintain engine coolant concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corro -
sion protection of your engine which contains
aluminum components.
WARNING!
Do not open hot engine cooling system. Never
add engine coolant (antifreeze) when the
engine is overheated. Do not loosen or
remove the cap to cool an overheated engine.
Heat causes pressure to build-up in the
cooling system. To prevent scalding or injury,
do not remove the pressure cap while the
system is hot or under pressure.
Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or
engine damage may result.

MATERIALS ADDED TO FUEL
Besides using unleaded gasoline with the proper
octane rating, gasolines that contain detergents,
corrosion and stability additives are
recommended. Using gasolines that have these
additives will help improve fuel economy, reduce
emissions, and maintain vehicle performance. Designated TOP TIER Detergent
Gasoline contains a higher level of
detergents to further aide in minimizing
engine and fuel system deposits. When
available, the usage of TOP TIER Detergent
gasoline is recommended. Visit
www.toptiergas.com for a list of TOP TIER
Detergent Gasoline Retailers.
Indiscriminate use of fuel system cleaning agents
should be avoided. Many of these materials
intended for gum and varnish removal may contain
active solvents or similar ingredients. These can
harm fuel system gasket and diaphragm materials.
FUEL SYSTEM CAUTIONS
NOTE:Intentional tampering with the emissions control
system can result in civil penalties being assessed
against you.
CAUTION!
Follow these guidelines to maintain your
vehicle’s performance:
The use of leaded gasoline is prohibited by
Federal law. Using leaded gasoline can impair
engine performance and damage the emis -
sions control system.
An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic
converter to overheat. If you notice a pungent
burning odor or some light smoke, your engine
may be out of tune or malfunctioning and may
require immediate service. Contact an autho -
rized dealer for service assistance.
The use of fuel additives, which are now being
sold as octane enhancers, is not recom -
mended. Most of these products contain high
concentrations of methanol. Fuel system
damage or vehicle performance problems
resulting from the use of such fuels or addi -
tives is not the responsibility of the manufac-
turer and may void or not be covered under
the New Vehicle Limited Warranty.
CAUTION!
