RSA (Road Sign Assist) *
The RSA system recognizes spe-
cific road signs using the camera
sensor and navigation system
(when data is available) to provide
information to the driver via the
multi-information display and
head-up display.
If the system judges that the vehicle
is being driven over the speed limit,
performing prohibited actions, etc.
in relation to the recognized road
signs, it alerts the driver using a
warning display and warning
buzzer *
. *
: This setting needs to be customized.
WARNING
■
Before using the RSA
Do not rely solely upon the RSA system.
RSA is a system which supports the
driver by providing information, but it is
not a replacement for a driver’s own
vision and awareness. Drive safely by
always paying careful attention to the
traffic rules.
Inappropriate or neg ligent driving could
lead to an unexpected accident.

Driving When the camera sensor recognizes a
sign or information of a sign is available
from the navigation system, the sign
will be displayed on the multi-informa-
tion display.
 When the driving support system
information is selected, a maximum
of 3 signs can be displayed. ( → P.76)  When a tab other than the driving
support system information tab is
selected, only a recognized speed
limit sign or do not enter sign (when
notification is necessary) will be dis-
played. ( → P.76)
If signs other than speed limit signs are rec-
ognized, they will be displayed in an over-
lapping stack under th e current speed limit
sign.
The following types of ro ad signs are recognized.Non-official or recently introduced traffic signs may not be recognized.Indication on the multi-informa-

: Displayed when speed limit information for th e road is available from the navigation sys-
tem
In the following situations, the RSA sys-
tem will alert the driver.
 When the vehicle speed exceeds
the speed warning threshold of the
speed limit sign displayed, the sign
display will be emphasized and a
buzzer will sound.
 When the RSA system recognizes a
do not enter sign and determines
that your vehicle has entered a
no-entry area, the displayed sign will
flash and a buzzer will sound.
Depending on the situation, traffic
environment (traffic direction, speed,
unit) may be detected incorrectly and a
warning display may not operate prop-
erly. ■

Interior features ●
When the engine 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.●
The system may not operate correctly if
more than one electr onic key is in the
vicinity or if the smart access system with
push-button start is used to unlock a pas-
senger door.●
The doors that can recall the air condi-
tioning setting *
when unlocked using the
smart access system with push-button
start can be changed. For details, contact
your Lexus dealer. *
: The doors that can recall the driving
position memory are changed at the
same time.■
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: ●
Engine speed and compressor operation
controlled to restri ct heating/cooling
capacity●
Fan speed restricted when automatic
mode is selected
To improve air condit ioning performance,
perform the following operations: ●
Turn off eco air conditioning mode
( → P.316) ●
Adjust the fan speed●
Turn off Eco drive mode ( → P.289)
■
When the outside temperature falls to
nearly 32°F (0°C)
The dehumidification function may not
operate even when “A/C” is selected.
■
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 sys-
tem. This may then cause odor to be
emitted from the vents.
●
To reduce potential odors from occur- ring:
• It is recommended that the air condition-
ing 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 pe riod of time imme-
diately after the air conditioning system is
started in automatic mode or with the
micro dust and pollen filter on. ●
When parking, the system automatically
switches to outside air mode to encour-
age better air circulation throughout the
vehicle, helping to reduce odors that
occur when starting the vehicle. ■
Using the voice command system
Air conditioning system can be operated
using voice commands. For details, refer to
the “NAVIGATION AND MULTIMEDIA
SYSTEM OWNER’S MANUAL”. ■

WARNING■
To prevent the windshield from fog-
ging up
Do not use the windshield defogger
switch during cool air operation in
extremely humid weather. The difference
between the temperature of the outside
air and that of the windshield can cause
the outer surface of the windshield to fog
up, blocking your vision.
■
When the outside rear view mirror
defoggers are operating
Do not touch the outside rear view mir-
ror surfaces, as they can become very
hot and burn you.
