AIR CONDITIONING
263
(e) Outside temperature display
Outside temperature is displayed on
the screen.
The displayed temperature ranges from
−40 _C( −40 _F) up to 50 _C (122 _F).
If the temperature shows “ −−” or “E”, take
your vehicle to your Lexus dealer.
In the following situations, the correct out-
side temperature may not be displayed, or
the display may take longer than normal to
change.
DWhen stopped, or driving at low
speeds (less than 12 mph [20 km/h])
DWhen the outside temperature has
changed suddenly (at the entrance/exit
of a garage, tunnel, etc.) (f) Operating tips
DTo help cool down the interior after
parking in the hot sun, drive for the first
few minutes with the windows open.
After the excess heat has blown away,
close the windows.
DMake sure the air inlet grilles in front of
the windshield are not blocked by
leaves or other obstructions.
DIf air flow control is not satisfactory,
check the dashboard vents and rear
vents. (See “(g) Adjusting the position
of and opening and closing the air out-
lets” on page 266.)
DKeep the area under the front seats
clear to allow air to circulate through-
out the vehicle.
DOn cold days, set the fan speed to high
for a minute to help clear the intake
ducts of snow or moisture. This can re-
duce the amount of fogging on the win-
dows.
DWhen driving on dusty roads, close all
windows. If dust thrown up by the ve-
hicle is still drawn into the vehicle after
closing the windows, it is recom-
mended that the air intake control but-
ton be set to the OUTSIDE AIR mode
to take in the fresh air and set the fan
speed selector to any setting except
OFF.
DIf following another vehicle on a dusty
road, or driving in windy and dusty
conditions, it is recommended that the
air intake control button be temporarily
pressed in to the RECIRCULATED AIR
mode, which will close off the outside
passage and prevent outside air and
dust from entering the vehicle interior.
