Air Conditioner Maintenance  
WARNING!  
For best possible performance, your air conditioner  
should be checked and serviced by an authorized dealer  
at the start of each warm season. This service should  
include cleaning of the condenser fins and a system  
performance check. Drive belt tension should also be  
checked at this time.  
Use only refrigerants and compressor lubricants  
approved by the manufacturer for your air condi-  
tioning system. Some unapproved refrigerants are  
flammable and can explode, injuring you. Other  
unapproved refrigerants or lubricants can cause  
the system to fail, requiring costly repairs. Refer to  
the “Warranty and Maintenance Booklet” for fur-  
ther warranty information.  
CAUTION!  
Do not use chemical flushes in your air conditioning  
system as the chemicals can damage your air condi-  
tioning components. Such damage is not covered by  
the New Vehicle Limited Warranty.  
The air conditioning system contains refrigerant  
under high pressure. To avoid risk of personal  
injury or damage to the system, adding refrigerant  
or any repair requiring lines to be disconnected  
should be done by an experienced repairman.

Refrigerant Recovery And Recycling  
WARNING!  
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 an authorized dealer or other an  
authorized service facility using recovery and recycling  
equipment.  
Do not remove the A/C air filter while the blower is  
operating or personal injury may result.  
The A/C air filter is located in the fresh air inlet behind  
the lower glove box. Perform the following procedure to  
replace the filter:  
NOTE: Use only manufacturer approved A/C System  
Sealers, Stop Leak Products, Seal Conditioners, Compres-  
sor Oil, or Refrigerants.  
1. Open the glove compartment and remove all contents.  
2. Push in on the sides of the glove compartment and  
lower the door.  
A/C Air Filter – If Equipped  
Refer to the “Warranty and Maintenance Booklet” for the  
proper maintenance intervals.  
3. Pivot the glove compartment downward.  
4. Disengage the two retaining tabs that secure the filter  
cover to the HVAC housing, and remove the cover.

CAUTION!  
The A/C air filter is labeled with an arrow to indicate  
airflow direction through the filter. Failure to prop-  
erly install the filter will result in the need to replace  
it more often.  
7. Rotate the glove compartment door back into position.  
Body Lubrication  
Locks and all body pivot points, including such items as  
seat tracks, door hinge pivot points and rollers, liftgate,  
tailgate, sliding doors and hood hinges, should be lubri-  
cated periodically with a lithium based grease to assure  
quiet, easy operation and to protect against rust and  
wear. Prior to the application of any lubricant, the parts  
concerned should be wiped clean to remove dust and  
grit; after lubricating excess oil and grease should be  
removed. Particular attention should also be given to  
hood latching components to ensure proper function.  
A/C Air Filter Replacement  
5. Remove the A/C air filter by pulling it straight out of  
the housing.  
6. Install the A/C air filter with the arrow on the filter  
pointing toward the floor. When installing the filter  
cover, make sure the retaining tabs fully engage the  
cover.

tions of salt or road film.  
The fluid reservoir for the windshield washers and the  
rear window washer is shared. It is located in the engine  
compartment and should be checked for fluid level at  
regular intervals. Fill the reservoir with windshield  
washer solvent (not engine coolant/antifreeze) and op-  
erate the system for a few seconds to flush out the  
residual water.  
Operation of the wipers on dry glass for long periods  
may cause deterioration of the wiper blades. Always use  
washer fluid when using the wipers to remove salt or dirt  
from a dry windshield.
