314 4-5. Using the driving support systems
RX450h_U_OM0E013U This mode employs a radar sensor to detect the presence of vehicles up to
approximately 400 ft. (120 m) ahead, determines the current vehicle-to-vehicle
following distance, and operates to main tain a suitable following distance from
the vehicle ahead. Note that vehicle-to-vehicle distance will close in when traveling on long downhill
slopes.
Example of constant speed cruising
When there are no vehicles ahead The vehicle travels at the speed set by the driver. The desired vehicle-to-vehicle dis-
tance can also be set by operating th e vehicle-to-vehicle distance button.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appears When a vehicle is detected running ahead of you, the system automatically deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the system
applies the brakes (the stop lights will come on at this time). The system will respond to
changes in the speed of the vehicle ahead in order to maintain the vehicle-to-vehicle
distance set by the driver. Approach wa rning warns you when the system cannot
decelerate sufficiently to prevent your ve hicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your ve hicle will also stop (vehicle is stopped by
system control). After the vehicle ahead starts off, pushing the cruise control lever up
or depressing the accelerator peda l will resume follow-up cruising.
Example of acceleration
When there are no longer any preceding vehicles driving slower than the set
speed The system accelerates until the set speed is reached. The system then returns to con-
stant speed cruising.Driving in vehicle-to-vehicle distance control mode

S-FLOW mode
In S-FLOW mode, priority for the airflow is given to the front seats, reducing
the airflow and air conditioning effect on the rear seats.
If a passenger is not detected in the front passenger seat, priority for the air-
flow will be given to the driver's seat only. In this case, the temperature indicator fo r the front passenger side will turn off.
S-FLOW mode will be activated automatically according to the set tempera-
ture, outside temperature, etc. (  P. 411)The indicator comes on when S-FLOW mode is on.■

Unlocking the vehicle using an electronic key and turning the power switch to ON
mode will recall that key’s registered air conditioning settings. ●
When the power switch is turned off, the curr ent air conditioning settings will automati-
cally be registered to the electronic key that was used to unlock the vehicle. ●
The system may not operate correctly if more th an one electronic key is in the vicinity or
if the smart access system with push-button start is used to unlock a passenger door. ●
The doors that can recall the air conditioni ng setting when unlocked using the smart
access system with push-b utton start can be changed.
* For details, contact your Lexus
dealer.
* : The doors that can recall the driving positi on memory are changed at the same time.■
Using automatic mode
Fan speed is adjusted automatically accordin g to the temperature setting and the ambi-
ent conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow immediately
after the “AUTO” button is pr essed or “AUTO” is selected.■

When the outside temperature exceeds 75  F (24  C) and the air conditioning system
is on ●
In order to reduce the air conditioning po wer consumption, the ai r conditioning system
may switch to recirculated air mode automatically.
This may also reduce fuel consumption. ●
Recirculated air mode is selected as a default mode when the power switch is turned to
ON mode. ●
It is possible to switch to outside air mode at any time by pressing the outside/recircu-
lated air mode button. ■
Automatic mode for air intake control
In automatic mode, the system detects exhaust gas and other pollutants and automati-
cally switches between outside air and recirculated air modes.
When the dehumidification function is off, and the fan is operating, turning automatic
mode on will activate the dehumidification function.■
Fogging up of the windows ●
The windows will easily fog up when the humidi ty in the vehicle is high. Selecting “A/C”
will dehumidify the air from the outlet s and defog the windshield effectively. ●
If you turn “A/C” off, the windows may fog up more easily. ●
The windows may fog up if the recirculated air mode is used.
