3-6 Air Conditioning
The air conditioner cools, dehumidifies and filters the
air for the inside of the vehicle.
The air conditioning compressor is enabled in all modes
unless the A/C ON button is in the off position (the
indicator light will not be illuminated). However, the air
conditioning compressor will not operate when the
outside temperature is below 42
F (7
C). When the air
conditioner is on, you may sometimes notice slight
changes in your vehicle's engine speed and power. This
is normal, because the system is designed to cycle the
compressor on and off to keep the desired cooling and
help fuel economy.
On very hot days, open the windows long enough to let
the hot air out. This reduces the time required to cool the
interior of the vehicle to a comfortable level. If the
system is in the automatic mode (AUTO
-PUSH knob
indicator light is on), during very hot days the system
will automatically go to the RECIRC ON mode and the
temperature door will be positioned at the full cold
position for maximum cooling. You can choose the
extreme comfort setting of 60
F (16
C), but the
system will not cool any faster by choosing the extreme
comfort setting.
Heating
In cold weather, if the automatic mode is selected
(AUTO
-PUSH knob indicator light is on), the system
will automatically direct the airflow out of the lower
floor outlets and the temperature door will be positioned
at the full hot position. You can choose the extreme
comfort setting of 90
F (32
C), but the system will not
warm up any faster by selecting the extreme
comfort setting.
In cold weather, the system will delay turning on the fan
to avoid blowing cold air. The length of the delay
depends on the engine coolant temperature and the
outside temperature. The fan speed will increase as the
temperature of the engine coolant increases. Turning the
AUTO FAN knob will override this delay by turning off
the automatic fan control mode and changing the
fan speed.

Engine Air Cleaner/Filter
The air cleaner and filter are on the driver's side of the
engine compartment.
To check or replace the air filter:
1. Remove the radiator hose from the resonator channel.
2. Release the tension of the wing screw clamp on the
air intake hose where it attaches to the air cleaner
cover near the top of the engine. Just turn the wing
screw counterclockwise, then detach the hose from
the air cleaner cover.
3. To remove the air cleaner cover, push the hose and
resonator assembly rearward and up, and hold them
out of the way.

6. Remove the air filter.
7. Install the new air filter and reverse all of the steps to
reinstall the cover, electrical wires, hose and clamp.
Be sure the tabs of the air cleaner cover fit into the
slots of the air cleaner housing. Then make sure both
clamps are fully engaged.
Refer to the Maintenance Schedule to determine when to
replace the air filter.
See ªScheduled Maintenance Servicesº in the Index.
CAUTION:
Operating the engine with the air cleaner/filter
off can cause you or others to be burned. The air
cleaner not only cleans the air, it stops flame if
the engine backfires. If it isn't there, and the
engine backfires, you could be burned. Don't
drive with it off, and be careful working on the
engine with the air cleaner/filter off.
NOTICE:
If the air cleaner/filter is off, a backfire can
cause a damaging engine fire. And, dirt can easily
get into your engine, which will damage it.
Always have the air cleaner/filter in place when
you're driving.

Scheduled Maintenance
7-5
The services shown in this schedule up to 100,000 miles
(166 000 km) should be performed after 100,000 miles
(166 000 km) at the same intervals. The services shown
at 150,000 miles (240 000 km) should be performed at
the same interval after 150,000 miles (240 000 km).
See ªOwner Checks and Servicesº and ªPeriodic
Maintenance Inspectionsº following.
Footnotes

The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to the
completion of the vehicle's useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the maintenance
be recorded.# Lubricate the suspension and steering linkage,
transaxle shift linkage, parking brake cable guides
and underbody contact points and linkage.
* Your vehicle has an Engine Oil Life Monitor. This
monitor will show you when to change the engine oil
and filter
-- usually between 3,000 miles (5 000 km)
and 7,500 miles (12 500 km) since your last oil change.
Under severe conditions, the indicator may come on
before 3,000 miles (5 000 km). Never drive your vehicle
more than 7,500 miles (12 500 km) or 12 months
without an oil and filter change.
The system won't detect dust in the oil. So if you drive
in a dusty area, be sure to change your oil and filter
every 3,000 miles (5 000 km) or sooner if the CHANGE
OIL SOON message appears. Remember to reset the
Oil Life Monitor whenever the oil is changed. For more
information, see ªEngine Oil Life Monitorº in the Index.
+ A good time to check your brakes is during tire
rotation. See ªBrake System Inspectionº under ªPeriodic
Maintenance Inspectionsº in Part C of this schedule.
