■
Situations in which the pre-collision system does not function properly
The system may not function effectively in situations such as the following: ●
On roads with sharp be nds or uneven surfaces●
If a vehicle suddenly moves in front of your vehicle, such as at an intersection●
If a vehicle suddenly cuts in front of your vehicle, such as when overtaking●
In inclement weather such as heav y rain, fog, snow or sand storms●
When your vehicle is skiddi ng with the VSC system off●
When an extreme change in vehicle height occurs●
When the axis of the radar is out of adjustment■
Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor contamination, etc. that results in the
sensors being unable to detect obstacles, the pre-collision system will be automati-
cally disabled. In this case, the system will not activate even if there is a collision pos-
sibility.■
When there is a malfunction in the system, or if the system is temporarily unus-
able
Warning lights and/or warning messages will turn on or flash. (  P. 7 3 3 , 74 3 )

3563-2. Using the air conditio ning system and defogger
■
When the outside temperature exceeds 75°F (24°C) and the air conditioning
system is on ●
In order to reduce the air conditioning power consumption, the air 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 .■
Window defogger feature
Recirculated air mode may automatically switch to outside air mode in situations
where the windows need to be defogged.■
When outside air temperature is below 32  F (0  C)
The cooling and dehumidification fu nction may not operate even when
is
pressed.■
When the indicator light on goes off
Press to turn on the cooling and dehumi dification function again. There may
be a problem in the air conditioning system if the indicator light goes off again
shortly after the button is pressed. Have it inspected by your Lexus dealer.■
Ventilation and air conditioning odors ●
To let fresh air in, set the air conditioning system to the outside air mode.●
During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning sy stem. This may then cause odor to be
emitted from the vents.●
To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic mode.
