The automatic climate control
system 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 f low f rom the
vents in the center and each side of
the dashboard is adjustable. Move
the tab in the center of each vent up-
and-down and side-to-side.
Thesideventscanbeopenedand
closed with the dials next to them.The climate control system draws air
through the exterior vents at the
bottom of the windshield. Keep
these vents clear of leaves and other
debris.For the climate control system to
provide heating and cooling, the

trol system is on (see page ). 132

When you set the temperature to its
lower limit (60°F/18°C) or its upper
limit (90°F/32°C), the system runs
at f ull cooling or heating only. It does
not regulate the interior temperature.
When the temperature is setbetween the lower and upper limits,
the system regulates the interior
temperature to the set value.
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 f rom its current level to
the set temperature. To put the Automatic Climate
Control in f ully-automatic mode,
press the AUTO button and set the
f an 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 either the
or button also goes
on to show you which is selected.
In cold weather, the f an will not
come on automatically until the
vehicle has been driven f or a short
time and the heater starts to develop
warm air.Pressing the OFF button shuts the
climate control system of f . Keep the
system of f only f or short periods. To
keep stale air and mustiness from
collecting, you should have the f an
