Air Conditioning
On very hot days, open the windows long enough to let
hot inside air escape. This reduces the time the
compressor has to run, which should help fuel economy.
For quick cool-down on very hot days, use
MAX with
the temperature knob all the way in the blue area. If this
setting is used. for long periods of time, the air in your
vehicle may become too dry.
For normal cooling on hot days, use
VENT with the
temperature knob
in the blue area and the NC'button
pushed
in. The system will bring in outside air and cool it.
On cool but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
You can use BI-LEVEL with the,terhperature
knob in
the middle and the
A/C button pushed in. The system
will bring
in outside air and direct it to your upper body,
while sending slightly warmed
air to your lower body.
You may notice this temperature difference more at
. '
some times than others.
J
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 heatkr, you can use
it to help your system provide warm air faster when it's
cold outside
(0" F (-1 8 O 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
For mild outside temperatures when little heating or
cooling is needed, use
VENT to direct outside air through
your vehicle. Your vehicle also has the flow-through
ventilation system described later in this section.
Defogging and Defrosting Windows
Your system' has two settings for clearing the front and
side windows. To defrost the windows'quickly, use
DEFROST with the temperature knob all the way in the
red area. To warrn passengers while keeping the
windows' clean, use
QEFOG.

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.
If the coolant inside the coolant recovery tank is boiling,
don’t do anything else (until it
cools down.

NOTICE:
Engine damage from running your engine
without coolant isn’t covered
by your warranty.
If there seems to be no leak, with the engine on check to
see if
the electric engine fan(s) are running. If the engine
is overheating, both fan(s) should be running. If they
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 clean
water (preferably distilled) and a proper antifreeze at the
coolant recovery ‘tank. (See “Engine Coolant” in the
Index for more information about the proper coolant
mix
.)

filler neck may be lower. If the level
is lower, add
more of the proper
mix through the filler neck until
the level reaches the base of the filler neck.

10. Then replace the

time during this
procedure if coolant
begins to flow out of
the filler neck, reinstall
the pressure cap. Be
sure the arrows on the
pressure cap line up
like this.
11. Check the coolant in the recovery tank. The level in
the coolant recovery tank should be at the HOT
mark when the engine
is hot or at the COLD mark
when the engine
is cold.
If a Tire Goes Flat
It’s unusual for a tire to “blow out” while you’re \
driving,
especially
if you maintain your tires properly. If air goes
out
of a tire, it’s much more likely to leak out slowly.
But if you should ever have a “blowout,” here are a few
tips about what to expect and what to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot
off the
accelerator pedal and grip the steering wheel firmly.,
Steer to maintain lane position, then gently brake to a
stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go.
It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop, well
off the road if possible.
If a tire goes flat, the next part shows how to
use your
jacking equipment to change a flat tire safely.

NOTICE:
~f you use an improper coolant mix, your engine
could overheat and be badly damaged. The repair cost wouldn’t be covered by your
warranty. Too much water in the mix can freeze
and crack the engine, radiator, heater core and
other parts.
..
To Check Coolant
When your engine is cold, the coolant level should be at
the
COLD mark or a little higher. When your engine is
warm, the level should be up to the HOT mark or a little
higher.
