RX400h_URear outlets
Direct air flow to the left or right,
up or down
Turn the knob up to open the
vent and down to close the vent
■Using the automatic mode
Fan speed is adjusted automatically in accordance with the temperature setting and
ambient conditions. As a result, the following may occur.
●The system may switch automatically to recirculated air mode when the coolest
temperature setting is selected in summer.
●Immediately after the switch is pressed, the fan may stop for a while until warm or
cool air is ready to flow.
●Cool air may flow to the area around the upper body when the heater is on.
■Using the system in recirculated air mode
The windows will fog up more easily if the recirculated air mode is used for an
extended period.
■Window defogger feature
Recirculated air mode may automatically switch to outside air mode in situations
where the windows need to be defogged.
■Outside air temperature approaches 32
°F (0 °C).
The air conditioning system may not operate even when is pressed.
■When the indicator light on flashes
Press and turn off the air conditioning system before turning it on once
more. There may be a problem in the air conditioning system if the indicator light
continues to flash. Turn the air conditioning system off and have it inspected by your
Lexus dealer.

■After a fuse is replaced
●If the lights do not turn on even after the fuse has been replaced, a bulb may need
replacement. (→P. 3 6 5 )
●If the replaced fuse blows again, have the vehicle inspected by your Lexus dealer.
■If there is an overload in the circuits
The fuses are designed to blow before the entire wiring harness is damaged.
CAUTION
■To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failing to do so may cause damage, and possibly a fire or injury.
●Never use a fuse of a higher amperage rating than indicated, or use any other
object in place of a fuse.
●Always use a genuine Lexus fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.
This can cause extensive damage or even fire.
●Do not modify fuses or the fuse box.
