the speed notific ation threshold
of the speed limit sign displayed,
the sign display will be empha -
sized and a buzzer will sound.
 When the RSA system recog-
nizes a no-entry sign and detects
that the vehicle has entered a
no-entry area based on the map
information of the navigation sys -
tem, the no-entry sign flashes
and a buzzer will sound. (For
vehicles with navigation system)
 If it is detected that your vehicle
is overtaking when a no overtak -

3805-5. Using the driving support systems
When a vehicle is de tected running ahead of you, the system automatically deceler-
ates your vehicle. When a great er reduction in vehicle speed is necessary, the sys-
tem 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 vehi-
cle-to-vehicle distance set by the driver. Approach warning war ns you when the sys-
tem cannot decelerate sufficiently to prevent your vehicle from closing in on the
vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also sto p (vehicle is stopped
by system control). After the veh icle ahead starts off, pressing the “+RES” switch or
depressing the accelerator pedal (start-off operation) will res ume follow-up cruising.
If the start-off operation is not performed, system control continues to keep your
vehicle stopped.
When the turn signal lever is operated and your vehicle moves t o an overtaking lane
while driving at 50 mph (80 km/h) or more, the vehicle will acc elerate to help to over-
take a passing vehicle.
The system’s identificat ion of what is an overtaking lane may be determined solely
based on the location of the ste ering wheel in the vehicle (left side driver position
versus right side driv er position.) If the vehicle is driven to a region where the over-
taking lane is on a different sid e from where the vehicle is normally driven, the vehi-
cle may accelerate when the turn signal lever is operated in th e opposite direction to
the overtaking lane (e.g., if th e driver normally operates the vehicle in a region
where the overtaking lane is to t he right but then drives to a region where the over-
taking lane is to the left, the vehicle may accelerate when the right turn signal is acti-
vated).
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
constant speed cruising.
1 Press the cruise control main
switch to activate the cruise con -
trol.
Dynamic radar cruise control indicator
will come on and a message will be dis - played on the multi-information display.
Press the switch again to deactivate the
cruise control.

■Brake operation
A brake operation sound may be heard
and the brake pedal response may change, but these ar e not malfunctions.
■Warning messages and buzzers for
dynamic radar cruise control with full-speed range
Warning messages and buzzers are
used to indicate a system malfunction or to inform the driver of the need for cau -
tion while driving. If a warning message
is shown on the multi-information dis - play, read the messa ge and follow the
instructions. ( →P.353, 578)
■When the sensor may not be cor-
rectly detecting the vehicle ahead
In the case of the following and depend -
ing on the conditions, operate the brake
pedal when deceleration of the system is insufficient or ope rate the accelerator
pedal when acceleration is required.
As the sensor may not be able to cor - rectly detect these types of vehicles, the
approach warning ( →P.383) may not be
activated.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving in the same lane
●Vehicles with small rear ends (trailers with no load on board, etc.)

WARNING
■Limitations of the Parking Sup -
port Brake system
Do not overly rely on the system, as doing so may lead to an accident.
Always drive while checking the
safety of the surroundings of the vehi - cle.
Depending on the v ehicle and road
conditions, weather, etc., the system
may not operate.
The detection capabilities of sensors
and radars are limited. Always drive
while checking the safety of the sur- roundings of the vehicle.
●The driver is solely responsible for safe driving. Always drive carefully,
taking care to observe your sur -
roundings. The Parking Support Brake system is designed to pro-
vide support to lessen the severity
of collisions. However, it may not operate in som e situations.
●The Parking Support Brake system is not designed to stop the vehicle
completely. Additionally, even if the
system has stopped the vehicle, it is necessary to depress the brake
pedal immediately as brake control
will be canceled after approximately 2 seconds.
●Do not attempt to test the operation of the Parking Support Brake sys -
tem yourself such as intentionally
driving to a vehicle or wall. Depending on the situations, the
system may not ope rate properly,
possibly leading to an accident.
NOTICE
■If “PKSB Unavailable” is dis -
played on the multi-information
display and the PKSB OFF indi - cator illuminates
If this message is displayed immedi -
ately after the power switch is changed to ON, ope rate the vehicle
carefully, paying attention to your sur -
roundings. It may be necessary to
drive the vehicle for a certain amount of time before the system returns to
normal. (If the syst em does not return
to normal after driving for a while, clean the sensors and their surround -
ing area on the bumpers.)

■Heating
●In HV mode, the gasoline engine may
operate in order to extract heat from the engine coolant via the heater.
●In EV mode, heating is done by a heat pump system.
• When the outside t emperature is low
or it is snowing, compared to conven - tional vehicles, heating may be less
effective and warm air may not come
out. • When the outside heat exchanger is
frosted over, fan speed declines and it
may become harder to heat the inte- rior. However, it is not a malfunction.
In this situat ion, the air temperature
from the outlets may not change even though the set tem perature is raised.
• If frost has formed of the outside heat
exchanger, the heating performance will decline. The frost can be removed
from the outside heat exchanger by
operating the Remote Air Conditioning System before driving ( →P.460).
When frosted over, the heating opera -
tion of the Remote Air Conditioning System starts after defrosting.
• When “AUTO” switch is turned on, the
heating is controlle d optimally. There- fore, the set heating performance may
not be achieved even if the fan speed
setting is increased.
Outside heat exchanger
●In the following situations the gasoline
engine may operate in order to extract heat from the engine coolant via the
heater even in EV mode.
• The outside temperature is approxi -

●During use, various odors from inside
and outside the vehicle may enter into and accumulate in the air conditioning
system. This may t hen cause odor to
be emitted from the vents.
●To reduce potential odors from occur -
ring: • It is recommended that the air condi-
tioning system be se t to outside air
mode prior to turning the vehicle off. • The start timing o f the blower may be
delayed for a short period of time
immediately after t he air conditioning system is started in automatic mode.
●When parking, the system automati- cally switches to outside air mode to
encourage better air circulation
throughout the vehicle, helping to reduce odors that occur when starting
the vehicle.

WARNING
■Cautions for using “My Room Mode”
Do not leave children, people who
need assistance, or pets inside the vehicle. The system may turn off
automatically and the interior tem-
perature may become high or low, resulting in heat stroke, dehydration
or hypothermia. Fa ilure to do so may
result in death or serious injury.
■To prevent the windshield from fogging up
Do not use the wi ndshield defogger
switch during cool air operation in extremely humid weather.
The difference bet ween the tempera-
ture of the outside air and that of the windshield can cause the outer sur -
face of the windshield to fog up,
blocking your vision.
■When the outside rear view mir -
ror defoggers are operating
Do not touch the rear view mirror sur -
faces when the out side rear view mir-
ror defoggers are on.
