Lights (CONT.)
When you close a door (or the last door
when more than one are open at the
same time), other lights will come on.
They are in your instrument panel and
the switches for your doors, headlamps,
radio, heating and air conditioning
systems
(if equipped).
These lights will go
off automatically
after about
30 seconds.

Rearview Mirror
To reduce glare from lights behind you,
pull the lever toward
you to the night
position.
Convex Outside Mirror
Your right side mirror is convex. A
convex mirror's surface is curved so you
can see more from the driver's seat.
1 CAUTIVN
I
If you aren't used to a convex
mirror, you can hit another
vehicle. A convex mirror can make
things (like other vehicles) look
farther away than they redly are. If
you cut too sharply into the right
lane, you could hit a vehicle on
youi right. Check your inside
mirror
or glance over your shoulder II
before changing lanes.

Downloaded from www.Manualslib.com manuals search engine Air Conditioning (OPTION)
There are three air conditioning
settings:
MAX: Provides maximum cooling or
quick cool-down on very hot days. 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.
A/C 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 Use on cool, but sunny days.
This setting brings in the 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.
OFF: Press to turn the system off.
Some air will still come from the outlets
at the floor. Press any function button
to turn the system on. On
very hot days, open the windows
long enough to let hot inside air escape.
This reduces the time your air
conditioner’s compressor will have to
run, which should help fuel economy.
The air conditioner compressor operates in
all three air conditioning
settings.
It also operates in BLEND and
ljjjl (Defrost) when the temperqture is
above freezing. This helps remove
moisture from the air inside your
vehicle.

Air Conditioning (CONT.)
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 the
VENT and HEAT 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.
HEAT When outside temperatures are
cold, push
HEAT. This will send most
of the heated air through the ducts near
the floor. The rest will come out of the
defroster vents and side window
defogger vents.
Defogging and Defrosting
There are two settings for clearing your
windows. For each setting, adjust the
temperature control as desired. The air
conditioner compressor will run in
these settings to remove moisture from
the air when the temperature is above
freezing.
BLEND: This setting allows half of the
air to flow to the floor heater ducts, and
half to
go to the windshield and side
window vents located in the windshield
pillars. Use this setting to warm
passengers while keeping the
windshield clear.
The setting directs
90
through the defroster vents and the side
window vents, and
10% to the floor.

Rear Window Defogger (CONT.)
Don’t use a razor blade 0.
something else sharp on the insid
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.

Flow-Through Ventilation System
Your Chevrolet’s flow-through
ventilation system supplies outside air
into the vehicle when it is moving.
Outside air will
also enter the vehicle
when the heater or the air conditioning
fan is running.
I
Ventilation Tips
Keep the hood and front air inlet free
of ice, snow, or any other obstruction
(such as leaves). The heater and
defroster will work far better,
reducing the chance of fogging the
inside of your windows.
When you enter a vehicle in cold
weather, set the blower fan to the
highest setting for a few moments
before driving
off. This helps clear the
intake ducts of snow and moisture,
and reduces the chance of fogging the
inside of your windows.
Keep the air path under the front
seats clear
of objects. This helps air to
circulate throughout your vehicle.
