NC button again.(the indicator light will go off).
On cool but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.

BI-LEVEL position, with
the temperature knob set for comfort and press the
A/C
button once (the indicator light will come on). The

Heating
On cold days, use FLOOR with the temperature knob all
the way in the red area. The system will bring in outside
air, heat it and send it to the floor ducts.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it’s
cold outside
(0°F (-18°C) or lower). An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See “Engine Coolant
Heater” in
the Index.
Ventilation System
Adjust the direction of airflow by moving the louvered vents.
Your vehicle’s flow-through ventilation system supplies outside air into the vehicle when
it is moving. Outside
air will also enter the vehicle when the air conditioning
fan is running.
For mild outside temperatures when little heating or
cooling is needed,
use VENT to direct outside air
through your vehicle.

If Steam Is Coming From Your Engine
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine
if you see or hear steam coming
from it. Just turn it off and get everyone away
from the vehicle until
it cools clown. Wait until
there
is no sign of steam or coolant before
opening the
hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire, You or
others could be badly burned. Stop your engine if
it overheats, and get out of the vehicle until the
engine
is cool.

driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be

at or above the COLD
mark on a cold engine. The coolant level should be
at or above the HOT mark on a hot engine. If it isn’t,
you may have a leak
in the radiator hoses, heater
hoses, radiator, water pump or somewhere else in
the cooling system.

aren’t, your vehicle needs service.
How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the COLD mark, add a 50/50 mixture of ckm
water (preferably distilled) and DEX-COOL”
(orange-colored, silicate-free) antifreeze at the coolant
recovery
tank. (See “Engine Coolant” in the Index for
more information.)
Adding only plain water to your cooling system
can be
dangerous. Plain water, or some other
liquid Eke alcohol, can boil before the proper
coolant
mix will. Your vehicle’s coolant warning
system
is set for the proper coolant mix. With
plain water or the wrong mix, your engine could
get too hot but you wouldn’t get the overheat
warning.
Your engine ‘could catch fire and you or
others could be burned. Use a
50/50 mix Q€ clean
water and
DEX-COOL antifreeze.
