Operating tips (type 2)
D
To cool off your Toyota after it has
been parked in the hot sun, drive with
the windows open for a few minutes.
This vents the hot air, allowing the air
conditioning to cool the interior more
quickly.
D
Make sure the air intake grilles in front
of the windshield are not blocked (by
leaves or snow, for example).
D
On humid days, do not blow cold air
on the windshield. The windshield could
fog up because of the difference in air
temperature on the inside and outside
of the windshield.
D
Keep the area under the front seats
clear to allow air to circulate through-
out the vehicle.
D
On cold days, push the fan speed se-
lector to adjust the fan speed high for
a minute to help clear the intake ducts
of snow or moisture. This can reduce
the amount of fogging on the windows.
