2003 Acura RSX air conditioning

The engine must be running f or the
heater and air conditioning to
generate hot and cold air. The heater
uses engine coolant to warm the air.
If the engine is cold, it will be several
minutes bef ore you f eel warm air
coming from the system.
The heating and cooling system
draws air through the exterior vents
at the bottom of the windshield.
Keep these vents clear of leaves and
other debris.
The direction of air f low f rom the
vents in the center and each side of
the dashboard is adjustable.
Open each vent by pushing on the
recess. Adjust the direction of air
flow by rotating the vent. The heating and cooling system in
your Acura has f ull heating,
ventilation, and air conditioning
capabilities. In combination with the
air conditioning, the system
maintains the interior temperature
you select. The system also adjusts
the fan speed and air flow direction
automatically depending on the set
temperature.

To use the heating and cooling
system in automatic mode, set the
system as f ollows.Set the f an control dial to AUTO.
Set the mode control dial to AUTO.
Turn the temperature control dial
to the desired temperature.
Select Fresh Air mode by pressing
the Recirculation button. The
indicator in the switch should be
off.
Turn on the A/C by pressing the
button. TurningthefancontroldialtoOFF
shuts the heating and cooling system
completely off. Keep the system
completely of f only f or short periods.
To keep stale air and mustiness from
collecting, you should have the f an
running at all times.
To heat or cool the interior f aster,
select Recirculation mode and set
the temperature control dial to the
upper or lower limit. The system runs of f ull cooling or
heating only. It does not regulate the
interior temperature. When the
temperature is set between the lower
and upper limits, the system
regulates the interior temperature to
the set value.

When you turn the A/C of f , the
system cannot regulate the inside
temperature if you set the dial below
the outside air temperature.
With A/C on, use the temperature
control dial to adjust the temperature
of the air f low to a comf ortable
setting.Air conditioning also removes mois-
ture from the air as it operates. You
can use it to def og the windows
quickly in cool or damp weather.
Used in combination with the heater,
it also makes the interior warm and
dry.Air conditioning places an extra load
on the engine. Watch the engine
coolant temperature gauge (see page
) when using the A/C in heavy
traf f ic or driving up long hills. If it
moves near the red zone, turn of f the
air conditioning until the gauge
reads normally.
You can manually set the system
controls f or ventilation, air condi-
tioning, heating, air f low direction,
and fan speed in various combination.
Pressing the A/C button turns the
air conditioning ON and OFF. The
indicator in the button lights when
the A/C is ON.

A cold engine uses more f uel than a
warm engine. It is not necessary to
‘‘warm-up’’ a cold engine by letting it
idle f or a long time. You can drive
away in about a minute, no matter
how cold it is outside. The engine
will warm up f aster, and you get
better f uel economy. To cut down on
the number of ‘‘cold starts,’’ try to
combine several short trips into one.
You can improve f uel economy by
driving moderately. Rapid acceler-
ation, abrupt cornering, and hard
braking use more f uel.
Always drive in the highest gear that
allows the engine to run and acceler-
ate smoothly.
The air conditioning puts an extra
load on the engine which makes it
usemorefuel.Turnoff theA/Cto
cut down on air conditioning use.
Use the f low-through ventilation
when the outside air temperature is
moderate.
Always maintain your car according
to the maintenance schedule. This
will keep it in top operating condition.
An important part of that mainte-
nance is the
(see page ). For
example, an underinf lated tire
causes more ‘‘rolling resistance,’’
which uses f uel. It also wears out
f aster, so check the tire pressure at
least monthly.
In winter, the build-up of snow on
your car’s underside adds weight and
rolling resistance. Frequent cleaning
helps your f uel mileage and reduces
thechanceof corrosion. Depending on traf f ic conditions, try
to maintain a constant speed. Every
time you slow down and speed up,
your car uses extra f uel. Use the
cruise control, when appropriate, to
increase f uel economy.
The condition of your car and your
driving habits are the two most
important things that affect the fuel
mileage you get.

µ
µ Being able to see
clearly in all directions and being
visible to other drivers are important
in all weather conditions. This is
more dif f icult in bad weather. To be
seen more clearly during daylight
hours, turn on your headlights.
Inspect your windshield wipers and
washers f requently. Keep the wind-
shield washer reservoir f ull of the
proper f luid. Have the windshield
wiper blades replaced if they start to
streak the windshield or leave parts
unwiped. Use the def rosters and air
conditioning to keep the windows
f rom f ogging up on the inside (see
page ).
Exercise extra caution when driving
in rain af ter a long dry spell. Af ter
months of dry weather, the f irst
rains bring oil to the surf ace of the
roadway, making it slippery.
Rain, f og, and snow conditions
require a dif f erent driving technique
because of reduced traction and
visibility. Keep your car well-
maintained and exercise greater
caution when you need to drive in
bad weather. The cruise control
should not be used in these
conditions. Always drive
slower than you would in dry
weather. It takes your car longer to
react, even in conditions that may
seem just barely damp. Apply
smooth, even pressure to all the
controls. Abrupt steering wheel
movements or sudden, hard appli-
cation of the brakes can cause loss of
control in wet weather. Be extra
cautious f or the f irst f ew miles
(kilometers) of driving while you
adjust to the change in driving
conditions. This is especially true in
snow. A person can f orget some
snow-driving techniques during the
summer months. Practice is needed
to relearn those skills. 107

The added weight, length, and
height of a trailer will af f ect your
vehicle’s handling and perf ormance,
so driving with a trailer requires
some special driving skills and
techniques.
Foryoursafetyandthesafetyof
others,taketimetopracticedriving
maneuvers bef ore heading f or the
open road, and f ollow the guidelines
discussed below.
Drive slower than normal in all
driving situations, and obey posted
speed limits f or vehicles with trailers.
If you have an automatic
transmission, use D position when
towing a trailer on level roads. D is
the proper shif t lever position to use
when towing a trailer in hilly terrain.
(See ‘‘’’ in the next
column f or additional gear
inf ormation.) Make turns more slowly and wider
than normal. The trailer tracks a
smaller arc than your vehicle, and it
canhitorrunoversomethingthe
vehicle misses. Allow more time and
distance f or braking. Do not brake or
turn suddenly as this could cause the
trailer to jackknif e or turn over.
When climbing hills, closely watch
your temperature gauge. If it nears
the red (Hot) mark, turn the air
conditioning of f , reduce speed and, if
necessary, pull to the side of the
road to let the engine cool.

Periodically check the engine’s
radiator and air conditioning
condenser f or leaves, insects, and
dirt stuck to the f ront surf ace. These
block the air f low and reduce cooling
ef f iciency. Use a light spray f rom a
hose or a sof t brush to remove them.
Run the air conditioning at least once
a week during the cold weather
months. Run it f or at least ten
minutes while you are driving at a
steady speed with the engine at
normal operating temperature. This
circulates the lubricating oil con-
tained in the ref rigerant.If the air conditioning does not get as
cold as before, have your dealer
check the system. Recharge the
system with Ref rigerant HFC-134a
(R-134a). (See Specif ications on page
.)
Your car’s air conditioning is a sealed
system. Any major maintenance,
such as recharging, should be done
by a qualif ied mechanic. You can do
a couple of things to make sure the
air conditioning works ef f iciently.

The condenser and radiator f ins bend
easily. Only use a low-pressure spray
or sof t-bristle brush to clean them.Whenever you have the air conditioning
system serviced, make sure the service
f acility uses a ref rigerant recycling
system. This system captures the
ref rigerant f or reuse. Releasing
ref rigerant into the atmosphere can
damage the environment.
