Air Vents
You will find air vents in the center and on the sides
of
your instrument
panel. You can move the vents to direct the flow of air, or close the vents
altogether. When you close a vent, it will increase the flow of air coming out
of any vents that are open.
If your vehicle does not have air conditioning, there are air vents in each kick
panel below the instrument panel. Each vent has
a
handle to open and close
it.
