Air Conditioning Before using your vehicle's conditioning, open the air windows to clear the vehicle of hot air.This reduces the time it takes for your vehicle to cool down. Then keep your windows closed for the air conditioner to work at its best. You can use MAX A/C with the temperature knob the in blue area when it's really hot outside and you needto cool the inside air quickly. MAX A/C lets in only alittle air from the outside. 1 ~ ~ ting On cold days, use HEATER with the temperature knob in the red area. Outside air will be brought in through the floor outlets. The heater works best if you keep your windows closed while using it. If you use the optional engine coolant heater before starting yourengine, your heating system will produce warmer air faster to heat the passenger compartment in cold weather. See "Engine Coolant Heater"in the Index. If you first use MAX A/C, you can then use A/C with the temperature knob in the blue area, as soon as the vehicle has cooleddown, so outside air will be going through your vehicle. If your vehicle hasrear air conditioning, setting it on LO may enhance front A/C performance by allowing trapped refrigerant inrear lines to circulate. When the air conditioning, DEFROST or BLEND is on, you may noticea slight increase or decrease in engine speed, due to compressor operation. This is normal because the system is designed cycle the compressor to on andoff to keep the desired temperature. 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 better, reducing the far chance of fogging the inside of your windows. When you enter a vehicle in cold weather, turn the blower fan to HI 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. 0 Keep the air path under the front seats clear of objects. This helps air to circulate throughout your vehicle. Your vehicle has air vents in the center and the sides on of your instrument panel. 3-6

Before
using
your
vehicle’s
air conditioning, open
the
windows to clear the
vehicle
of
hot
air. This reduces
the
time it takes for your vehicle to cool down. Then keep
your windows
closed for the air conditioner to work
at
its best.
You can use
MAX
A/C
with
the
temperature
knob
in the
blue area
when
it’s
really
hot
outside and
you
need to
cool
the inside air quickly.
MAX
A/C
lets in
only
a
little
air from the
outside.
If
you
first use
MAX
A/C,
you
can then use
A/C
with
the
temperature
knob
in
the
blue area, as soon
as
the
vehicle
has
cooled down,
so
outside air will
be
going
through
your
vehicle.
If your
vehicle
has
rear air conditioning, setting
it
on
LO
may enhance front
A/C
performance by allowing
trapped
refrigerant
in
rear lines
to
circulate.
When
the air conditioning, DEFROST or
BLEND
is
on,
you
may
notice
a
slight increase or decrease in engine
speed, due to compressor operation. This is
normal
because
the
system
is
designed
to
cycle the compressor
on
and off
to
keep the
desired
temperature.
On cold days,
use
HEATER
with
the
temperature
knob
in the
red area. Outside air will be brought
in
through
the floor outlets. The heater works
best
if
you keep your
windows
closed
while
using
it.
If
you
use
the
optional engine coolant heater
before
starting
your engine, your
heating system will
produce
warmer air faster to
heat
the
passenger
compartment
in
cold weather. See “Engine
Coolant
Heater”
in
the Index.
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,
turn
the
blower fan to HI 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.
Your vehicle
has
air
vents
in
the
center
and
on
the
sides
of
your
instrument
panel.
