To select the
temperature you want,
push the blue button
for a cooler setting and
the red button for a
warmer setting. The
temperature setting
will be displayed on
the digital screen.
You can select temperatures from 65
F (18 C) to 85 F (29 C). And, at
each end, you may choose
60 F (16 C), for maximum cooling, and 90 F
(33 OC), for maximum heating. We recommend when fiit getting familiar
with your vehicle, select 75
OF (24OC). You may find that your own personal
comfort requires a slightly higher or lower setting. Once you set the
temperature, the system
will automatically maintain the set temperature.
ECON
With this setting it’s all automatic, but the air conditioning compressor
does not operate and it won’t remove humidity from the air. However,
the system will try to keep the air at the selected temperature. Use this
setting in cold or cool weather to save fuel.
If it’s warm outside and you need to cool the air, use the next choice.
AUTO
With this setting, the air conditioning compressor cycles when needed to
cool the air and it’s all automatic.
In cold weather when the system senses
the need for heat, the air flow will
be directed out the floor ducts. As the
interior temperature approaches the desired setting, the blower speed
will decrease and the air flow could be directed through the defroster and
floor ducts.
To maintain interior comfort, the air flow may move to the air
outlets and floor ducts (Bi-level). On bright sunny days in cold weather,
the air flow could even come out the
A/C outlets to maintain comfort and
prevent stuffiness.

1-1 Push this button to
remove fog or frost
from the windshield.
This setting sends most of the air flow to the windshield with only a small
amount to the floor outlets. In some cold start conditions, the
“AUTO”
blower fan speed may be limited until the cooling system warms up. This
is normal to prevent windshield fogging.
The .fan speed will work automatically to maintain your requested interior
temperature. If
you need more air to your windshield, you should select a
higher fan speed.
It will help a lot if you first clear any ice and snow from the hood and the
air inlet (it’s between the hood and the windshield).
REAR DEFOGGER
I
Push this button to turn
on the rear defogger.
With it, your rear window and both outside rearview mirrors are heated.
The system will automatically shut off after
10 minutes. If further
defrosting is desired, simply push the button again.
NOTICE:
Scraping the inside of your rear window could cut and damage
the heating grids. Your warranty would not,cover this damage.
And don’t put decals there; you might have to scrape them.off.

Keep your vehicle in good shape. Check all fluid levels and also the
brakes, tires, cooling system and transaxle. These parts can work hard

continue to drive your vehicle.
If “ENGINE COOLANT HOT IDLE ENGINE’’ message appears on
the Driver Information Center, pull off to the side of the road as soon as
it is safe to do
so. When the vehicle is at a complete stop, shift the

Engine damage from running your engine without coolant isn’t
covered
by your warranty.
If there seems to be no leak, check to see if the electric engine fans are
running.
If the engine is overheating, both fans should be running. If they
aren’t, your vehicle needs service.
How to Add Coolant to the Coolant Surge Tank
If you haven’t found a problem yet, but the coolant level isn’t visible
inside the surge tank add a
50/50 mixture of clean water (preferably
distilled) and a proper antifreeze at the coolant surge tank, but be sure
the cooling system, including the coolant surge tank pressure cap, is cool
before you do it.
(See “Engine Coolant” in the Index for more
information about the proper coolant mix.)
If it isn’t, you may have a leak in the radiator fiose, heater hoses, radiator, -
water pump or somewhere else in the cooling system. -
