HONDA 2005 Civic Hybrid - Owner's Manual - Manual (Page 120)

You may notice that using the A/C
causes a greater drop in fuel
economy than you are used to in
other vehicles. Although the amount
of extra fuel used by the A/C load on
the engine is no greater than other
vehicles, it is more noticeable
because of your Civic Hybrid’s
excellent fuel mileage. Using the
A/C in hot weather may result in
fuel economy that is lower than
expected. The air conditioning puts an extra
load on the engine which makes it
use more fuel. Use the fresh-air
ventilation when possible.
If air conditioning is needed, you can
save some fuel by using the A/C in
‘‘ECON’’ mode. When the outside
temperature is above freezing, this
mode allows the Auto Idle Stop
function to shut off the engine when
the vehicle is stopped, resulting in
fuel savings.
