Acura 2010 TSX - Manual (Page 120)

Push the button under the audio
controls to turn on the hazard
warning lights (four-way flashers).
This causes all four outside turn
signal lights and both turn signal
indicators in the instrument panel to
flash. Use the hazard warning lights
if you need to park in a dangerous
area near heavy traffic, or if your
vehicle is disabled. The rear window defogger will clear
fog, frost, and thin ice from the
window. Push the defogger button to
turn it on and off. The indicator in
the button comes on to show the
defogger is on. It also shuts off when
you turn off the ignition switch. You
have to turn the defogger on again
when you restart the vehicle.
The defogger will shut itself off
within about 10 to 30 minutes
according to the outside temperature
(over 32°F, 0°C).
Make sure the rear window is clear
and you have good visibility before
starting to drive.
The defogger and antenna wires on
the inside of the rear window can be
accidentally damaged. When
cleaning the glass, always wipe side-
to-side.
Pushing this button also turns the
mirror heaters on or off. For more
