5-3. Using the air conditioning system
Interior features
Q When driving on dusty roads
Close all windows. If dust thrown up by the
vehicle is still drawn into the vehicle after
closing the windows, it is recommended
that the air intake mode be set to outside air
mode and the fan speed to any setting
except off.
Q Outside/recirculated air mode
O Setting to the recirculated air mode tem-
porarily is recommended in preventing
dirty air from entering the vehicle interior
and helping to cool the vehicle when the
outside air temperature is high.
O Outside/recirculated air mode may
automatically switch regardless of the air
conditioning setting depending on the
temperature setting or inside tempera-
ture.
Q Registering air conditioning settings to
electronic keys
O Unlocking the vehicle using an electronic
key and turning the power switch to ON
mode will recall that key’s registered air
conditioning settings.
O When the power switch is turned off, the
current air conditioning settings will auto-
matically be registered to the electronic
key that was used to unlock the vehicle.
O The system may not operate correctly if
more than one electronic key is in the
vicinity or if the smart entry & start system
is used to unlock the passenger door.
O Vehicles with the driving position mem-
ory: The doors that can recall the air con-
ditioning setting
*
when unlocked using
the smart entry & start system can be
changed. For details, contact any autho-
rized Lexus retailer or Lexus authorized
repairer, or any reliable repairer.
*
: The doors that can recall the driving posi-
tion memory are changed at the same
time.
Q Operation of the air conditioning sys-
tem in Eco drive mode
In Eco drive mode, the air conditioning sys-
tem is controlled as follows to prioritize fuel
efficiency:
O Engine speed and compressor operation
controlled to restrict heating/cooling
capacity
O Fan speed restricted when automatic
mode is selected
To improve air conditioning performance,
perform the following operations:
O Adjust the fan speed
O Turn off Eco drive mode (P.267)
Q When the outside temperature falls to
nearly 0°C (32°F)
The dehumidification function may not
operate even when “A/C” is selected.
Q Ventilation and air conditioning odors
O To let fresh air in, set the air conditioning
system to the outside air mode.
O During use, various odors from inside
and outside the vehicle may enter into
and accumulate in the air conditioning
system. This may then cause odor to be
emitted from the vents.
O To reduce potential odors from occur-
ring, the start timing of the blower may be
delayed for a short period of time imme-
diately after the air conditioning system is
started in automatic mode.
O When parking, the system automatically
switches to fresh air intake mode to
encourage better air circulation through-
out the vehicle, helping to reduce odors
that occur when starting the vehicle.
