Press
LO to lower the fan speed, HI to
raise it.
Air Conditioning
On very hot days, open the windows
long enough to let hot inside air escape.
This reduces the time it takes for your
vehicle to cool down, which should help
fuel economy.
There are three
air conditioning settings:
MAX: Provides maximum cooling or
quick cool-down on very hot days. This
setting also helps prevent outside odors
from entering your vehicle.
This setting recirculates much of the air
inside your vehicle, and it should not be
used for long periods because the air
may become too cold and dry. This
setting is not recommended if an
occupant is smoking.
NORM: Use for normal cooling on hot
days. This setting brings in outside air, cools
it and directs it through the
instrument panel outlets.
BI-LEV (Bi-Level): Use on cool, but
sunny days. This setting brings in
outside air, but directs it in two ways.
The cool air is directed to the upper
portion of your body through the
instrument panel outlets, but most
warmed air is directed through the
heater ducts and a little to the defrost
and side window vents. At times this
temperature difference may be more
apparent than others.
Heating and Ventilation
When you don’t need to cool the
outside air, use these next settings. You
can leave the air as it is or heat it.
The air conditioner compressor doesn’t
run in these settings. This reduces the
engine load, resulting in improved fuel
economy (gas mileage).
VENT: For mild outside temperatures,
when little heating or cooling is needed,
push
VENT. Air flow is through the
instrument panel outlets. Slide the
temperature control lever to a
comfortable level.

(OPTION)
This system allows you to set the
temperature
you want. It also lets you
choose automatic air flow and direction
control, or air flow and direction
settings you select. Your vehicle also
has the flow-through ventilation system
described later in this section.
The digital screen displays the outside
temperature, the inside temperature
setting and the fan speed.
When you select the
AUTO mode, the
air conditioner compressor
will operate
if the outside temperature is above
freezing.
The air conditioner compressor also
operates in
DEFOG, DEF (Defrost) and
BI-LEV (Bi-Level)
when the
outside temperature is above freezing.
COOL/WARM: Sets the interior
temperature you want. Press
COOL to
lower the inside temperature setting;
press
WARM to raise the setting. The
temperature you set will be displayed on
the digital screen.
Once you set the temperature, the
system will try to maintain the set
temperature, whether. you are using the
heating or cooling controls.
Your system has an interior
temperature sensor that dete.cts
increased interior temperature caused
by sunlight. To keep you comfortable, it
reduces the interior temperature by as
much as
5°F (3°C) below the setting on
the digital screen.
AUTO: To allow the system to
automatically control the temperature,
air distribution and fan speed:
1. Set the temperature you want with
the
COOL/WARM switch.
2. Press the AUTO switch. The AUTO
symbol will appear on the digital
screen.
The system will approach the
temperature you select as quickly as
possible.
For most efficient operation,
just set the system temperature where
you would like it and drive away.
You may notice a delay of three or four
minutes before the blower comes on.
OUTS TEMP: Press to have the
outside temperature displayed
on the
digital screen. Press
again to return to
the inside temperature setting.
If the system is left in the outside
temperature mode, the outside
temperature will be displayed except
when changing the inside temperature
setting using the
COOL/WARM
switch. The display will return to the
outside temperature setting in about
five seconds.

Steering Wheel Touch Controls
for Climate Control
(OPTION)
Some heating and cooling controls can
be adjusted at the steering wheel. These
touch controls also operate some audio
controls. See the
Index under Steering

FAN: Press the upper part of the
control to increase the fan speed; press
the lower part to reduce the fan speed.
TEMP: Press the upper part of the
control to raise the inside temperature
setting; press the lower part to lower
the setting.

Rear Window Defogger
R. DEFOG: Press to warm the
defogger grid on the rear window. The
indicator light will glow while the rear
window defogger is operating. The rear
window defogger will turn
off
automatically after about 10 minutes of
use. If you turn it on again, the defogger
will operate for about five minutes only.
You can also turn the defogger off by
turning off the ignition or pressing the
R. DEFOG switch again.
Do not attach a temporary vehicle
license across the defogger grid on the
rear window.
NOTICE:
Don’t use a razor blade or
something else sharp on the inside
of the rear window.
If you do, you
could cut or damage the warming
grid, and the repairs wouldn’t be
covered by your warranty.

There is something about an easy
stretch
of road with the same scenery,
along with the hum
of the tires on the
road, the drone of the engine, and the
rush of the wind against the vehicle that
can make you sleepy. Don’t let it
happen to
you! If it does, your vehicle
can leave the road in
less than a
second, and you could crash and be
injured.
What can you do about highway
hypnosis? First, be aware that it can
happen.
Then here are
some tips:
Make sure your vehicle is well
ventilated, with a comfortably cool
interior.
Keep your eyes moving. Scan the road
ahead and to the sides. Check your
rearview mirrors and your
instruments frequently.
If you get sleepy, pull off the road into
a rest, service, or parking area and
take
a nap, get some exercise, or both.
For safety, treat drowsiness on the
highway as an emergency.
Hill and Mountain Roads
Driving on steep hills or mountains is
different from driving in flat or rolling
terrain.
If you drive regularly in steep country,
or
if you’re planning to visit there, here
are some tips that can make your trips
safer and more enjoyable.
Keep your vehicle in good shape.
Check all fluid levels and also the
brakes, tires, cooling system and
transaxle. These parts can work hard
on mountain roads.
Know how to go down hills. The most
important thing to lmow is this: let
your engine do some
of the slowing
down. Shift to
a lower gear when you
go down a steep or long hill.
Ihow how to go uphill. You may
want to shift down to a lower gear.

Mainfenance When Trailer Towing
Your vehicle will need service :nore
often when you’re pulling a trailer. See
the
Maintenance Schedule for more on
this. Things that are especially
important in trailer operation are
automatic transaxle fluid (don’t
overfill), engine oil, belts, cooling
system, and brake adjustment. Each of
these is covered in this manual, and the
Index will help you find them quickly. If
you’re trailering, it’s a good idea to
review these sections before you start
your trip.
Check periodically to see that all hitch
nuts and bolts are tight.

Cooling System
When you decide it’s safe to lift the
hood, here’s what you’ll see:
(A) Coolant recovery tank
(€3) Radiator pressure cap
(C) Electric engine fans If
the coolant inside the coolant
recovery tank
is boiling, don’t do
anything else until it cools down.
The coolant level should be at or above
the
COLD mark. 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.

Use
a mixture of one-half dean-water
(preferably distilled) and one-half
antifreeze that meets
“GM Specificatkm
1825-M,” which won’t damage
aluminum parts.
You can also use a
recycled coolant conforming
to GM
Specification 1825-M with
a complete coolant
flush and refill.
If you use this
mixture, you don’t need to add
anything
else.
