temperature control Acura TL 2000 3.2 User Guide

Climate Control System
The automatic climate controlsystem in your Acura picks the
proper combination of air condi-
tioning, heating, and ventilation to maintain the interior temperature
you select. The system also adjusts the fan speed and air flow levels.
The direction of air flow from the vents in the center and each side ofthe dashboard, and in back of thecenter console is adjustable.
To adjust the air flow from each vent, move the tab in the center of each
vent up-and-down and side-to-side.
The side and rear vents can be opened and closed with the dials.CENTER VENTS
The climate control system draws airthrough the exterior vents at the
bottom of the windshield. Keep
these vents clear of leaves and otherdebris.
DRIVER'S-SIDE VENT
For the climate control system to
provide heating and cooling, the
engine must be running.

Fully-automatic Operation
To put the Automatic Climate Control in fully-automatic mode,
press the AUTO button and set the
fan control dial to AUTO, then set
the desired temperature by turning
the temperature control dial. You will see FULL AUTO in the system's
display. The light above the
button also shows you which
mode, Recirculation or Fresh Air, is selected.
The system automatically selects the proper mix of conditioned and/or
heated air that will, as quickly as
possible, raise or lower the interior
temperature from its current level to
the set temperature.

When you set the temperature to its lower limit (60°F/18°C) or its upper
limit (90°F/32°C), the system runsat full 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

Fuel Economy
The condition of your car and yourdriving habits are the two most
important things that affect the fuel
mileage you get.
Vehicle Condition 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 Owner MaintenanceChecks (see page 199). For
example, an underinflated tire
causes more "rolling resistance,"
which uses fuel. It also wears out
faster, 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 fuel mileage and reduces
the chance of corrosion. Driving Habits
You can improve fuel economy by driving moderately. Rapid acceler-
ation, abrupt cornering, and hard
braking use more fuel.
Always drive in the highest gear that allows the engine to run and acceler-
ate smoothly.
Depending on traffic conditions, try
to maintain a constant speed. Every
time you slow down and speed up,
your car uses extra fuel. Use the cruise control, when appropriate, to
increase fuel economy. A cold engine uses more fuel than a
warm engine. It is not necessary to
"warm-up" a cold engine by letting it
idle for a long time. You can drive away in about a minute, no matter
how cold it is outside. The engine
will warm up faster, and you get
better fuel economy. To cut down on
the number of "cold starts," try to combine several short trips into one.
The air conditioning puts an extra load on the engine which makes it
use more fuel. Turn off the A/C tocut down on air conditioning use.Use the flow-through ventilation
when the outside air temperature is moderate.
Before Driving

Driving in Bad Weather
Visibility — Being able to seeclearly in all directions and being
visible to other drivers are important in all weather conditions. This is
more difficult in bad weather. To be
seen more clearly during daylight
hours, turn on your headlights.
Inspect your windshield wipers and
washers frequently. Keep the wind- shield washer reservoir full of theproper fluid. Have the windshield
wiper blades replaced if they start to streak the windshield or leave parts
unwiped. Use the defroster and air
conditioning to keep the windows
from fogging up on the inside (see pages 112 and 118). Traction — Check your tires
frequently for wear and properpressure. Both are important in
preventing "hydroplaning" (loss of
traction on a wet surface). In the
winter, mount snow tires on all four
wheels for the best handling.
Watch road conditions carefully, they can change from moment tomoment. Wet leaves can be as slip-
pery as ice. "Clear" roads can have
patches of ice. Driving conditions
can be very hazardous when theoutside temperature is near freezing.
The road surface can become covered with areas of water puddlesmixed with areas of ice, so your
traction can change without warning.
Be careful when downshifting. If
traction is low, you can lock up the
drive wheels for a moment and cause
a skid. Be very cautious when passing, or
being passed by other vehicles. The spray from large vehicles reduces
your visibility, and the wind buffeting can cause you to lose control.
