Refrigerant Recovery And Recycling R134a —
If Equipped
R-134a Air Conditioning Refrigerant is a hydrofluoro-
carbon (HFC) that is endorsed by the Environmental
Protection Agency and is an ozone-saving product. How-
ever, the manufacturer recommends that air conditioning
service be performed by authorized dealer or other service
facilities using recovery and recycling equipment.
NOTE:Use only manufacturer approved A/C system PAG
compressor oil and refrigerants.
Refrigerant Recovery And Recycling — R–1234yf
R–1234yf Air Conditioning Refrigerant is a hydrofluo-
roolefin (HFO) that is endorsed by the Environmental
Protection Agency and is an ozone-friendly substance with
a low global-warming potential. The manufacturer recom-
mends that air conditioning service be performed by
authorized dealer using recovery and recycling equipment.
NOTE: Use only manufacturer approved A/C system
PAG compressor oil, and refrigerants.
Air Conditioning Filter Replacement (A/C Air Filter)
WARNING!
Do not remove the cabin air filter while the vehicle is
running, or while the ignition is in the ACC or ON/
RUN mode. With the cabin air filter removed and the
blower operating, the blower can contact hands and
may propel dirt and debris into your eyes, resulting in
personal injury.

SERVICING AND MAINTENANCE 463

CAUTION!
•The catalytic converter requires the use of unleaded
fuel only. Leaded gasoline will destroy the effective-
ness 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 involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and
vehicle.
Under normal operating conditions, the catalytic converter
will not require maintenance. However, it is important to
keep the engine properly tuned to assure proper catalyst
operation and prevent possible catalyst damage. NOTE:
Intentional tampering with emissions control sys-
tems 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 manufacturer’s specifications,
should be obtained immediately.
To minimize the possibility of catalytic converter damage:
• Do not shut off the engine or interrupt the ignition,
when the transmission is in gear and the vehicle is in
motion.
• Do not try to start the engine by pushing or towing the
vehicle.
• Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough idle
or malfunctioning operating conditions.

SERVICING AND MAINTENANCE 473

NOTE:When the vehicle has not been started or driven for
at least 30 days, an Extended Park Start Procedure is
required to start the vehicle. Refer to “Starting Procedures”
in “Starting And Operating” for further information.
CAUTION!
Before removal of the positive and negative terminals
to the battery, wait at least a minute with ignition
switch in the OFF position and close the drivers door.
When reconnecting the positive and negative terminals
to the battery be sure the ignition switch is in the OFF
position and the drivers door is closed.
BODYWORK
Protection From Atmospheric Agents
Vehicle body care requirements vary according to geographic
locations and usage. Chemicals that make roads passable in
snow and ice and those that are sprayed on trees and road
surfaces during other seasons are highly corrosive to the
metal in your vehicle. Outside parking, which exposes your
vehicle to airborne contaminants, road surfaces on which the
vehicle is operated, extreme hot or cold weather and other
extreme conditions will have an adverse effect on paint,
metal trim, and underbody protection.
The following maintenance recommendations will enable
you to obtain maximum benefit from the corrosion resis-
tance built into your vehicle.
What Causes Corrosion?
Corrosion is the result of deterioration or removal of paint
and protective coatings from your vehicle.
The most common causes are:
• Road salt, dirt and moisture accumulation.
• Stone and gravel impact.
• Insects, tree sap and tar.
• Salt in the air near seacoast localities.
• Atmospheric fallout/industrial pollutants.
Body And Underbody Maintenance
Cleaning Headlights
Your vehicle is equipped with plastic headlights and fog
lights that are lighter and less susceptible to stone breakage
than glass headlights.
Plastic is not as scratch resistant as glass and therefore
different lens cleaning procedures must be followed.

Fuel System Cautions
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 perfor-
mance and damage the emissions 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 your authorized dealer for service assistance.
• The use of fuel additives, which are now being sold
as octane enhancers, is not recommended. Most of
these products contain high concentrations of metha-
nol. Fuel system damage or vehicle performance
problems resulting from the use of such fuels or
additives is not the responsibility of the manufac-
turer and may void or not be covered under the New
Vehicle Limited Warranty. NOTE:
Intentional tampering with the emissions control
system can result in civil penalties being assessed against
you.Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon mon-
oxide poisoning:
• Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle
is stopped in an open area with the engine running
for more than a short period, adjust the ventilation
system to force fresh, outside air into the vehicle.
• Guard against carbon monoxide with proper main-
tenance. Have the exhaust system inspected every
time the vehicle is raised. Have any abnormal condi-
tions repaired promptly. Until repaired, drive with
all side windows fully open.
