QHands off steering wheel warning
In the following situations, a warning mes-
sage urging the driver to hold the steering
wheel and the symbol shown in the illustra-
tion are displayed on the multi-information
display to warn the driver. The warning
stops when the system determines that the
driver holds the steering wheel. Always
keep your hands on the steering wheel
when using this system, regardless of warn-
ings.
OWhen the system determines the driver is
not holding the steering wheel while the
lane centering function is operating.
If the driver continues to keep their hands
off of the steering wheel, the buzzer sounds,
the driver is warned and the function is tem-
porarily canceled. This warning also oper-
ates in the same way when the driver
continuously operates the steering wheel
only a small amount.
The buzzer also sounds even if the alert
type is set to .
OWhen the system determines that the
vehicle may deviate from the lane while
driving around a curve while the lane
centering function is operating.
Depending on the ve hicle condition and
road conditions, the warning may not oper-
ate. Also, if the system determines that the
vehicle is driving around a curve, warnings
will occur earlier than during straight-lane
driving.
OWhen the system determines that the
driver is driving with out holding the steer-
ing wheel while the steering wheel assist
of the steering assist function is operat-
ing. If the driver continues to keep their hands
off of the steering wheel and the steering
wheel assist is operating, the buzzer sounds
and the driver is warned. Each time the
buzzer sounds, the continuing time of the
buzzer becomes longer.
The buzzer also sounds even if the alert
type is set to .
QVehicle sway warning function
When the system determines that the vehi-
cle is swaying while the vehicle sway warn-
ing function is operating, a buzzer sounds
and a warning message urging the driver to
rest and the symbol shown in the illustration
are simultaneously displayed on the multi-
information display.
Depending on the vehicle and road condi-
tions, the warning may not operate.

*: If equipped
When the front camera recognizes a
sign and/or information of a sign is
RSA (Road Sign Assist)*
The RSA system recognizes spe-
cific road signs using the front cam-
era and/or navigation system
(when speed limit information is
available) to provide information to
the driver via the display.
If the system judges that the vehicle
is being driven over the speed limit,
performing prohibited actions, etc.
according to the recognized road
signs, it notifies the driver through a
visual notification and notification
buzzer.
WARNING
QBefore 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.
Indication on the multi-informa-
tion display

2024-5. Using the driving support systems

• Do Not Enter sign (when notification is
necessary)
If signs other than speed limit signs are rec-
ognized, they will be displayed in an over-
lapping stack under the current speed limit
sign.
The following types of road signs, including electronic signs and blinking
signs, are recognized.
A non-official or a recently introduced traf-
fic sign may not be recognized.
: Speed limit
: Do Not Enter
: Stop
: Yield
In the following situations, the RSA sys-
tem will notify the driver.
 When the vehicle speed exceeds
the speed notification 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

WARNING
QBefore using dynamic radar cruise
control with full-speed range
ODriving safely is the sole responsibility
of the driver. Do not rely solely on the
system, and drive safely by always pay-
ing careful attention to your surround-
ings.
OThe dynamic radar cruise control with
full-speed range provides driving
assistance to reduce the driver’s bur-
den. However, there are limitations to
the assistance provided.
Read the following conditions care-
fully. Do not overly rely on this system
and always drive carefully.
• When the sensor may not be correctly detecting the vehicle ahead: P.213
• Conditions under which the vehicle- to-vehicle distance control mode may
not function correctly: P.213
OSet the speed appropriately depend-
ing on the speed limit, traffic flow, road
conditions, weather conditions, etc.
The driver is responsible for checking

Driving
The vehicle travels at the speed set by the driver.
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 decelerates
your vehicle. When a greater reduction in vehicle speed is necessary, the system applies
the brakes (the stop lights will come on at th is 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 warning warns you when the system cannot decelerate sufficiently to
prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicl e will also stop (vehicle is stopped by sys-
tem control). After the vehicle ahead starts off, pressing the “+RES” switch or depressing
the accelerator pedal (start-off operation) will resume follow-up cruising. If the start-off
operation is not performed, system contro l continues to keep your vehicle stopped.
When the turn signal lever is operated and your vehicle moves to an overtaking lane while
driving at 50 mph (80 km/h) or more, the vehicle will accelerate to help to overtake a
passing vehicle.
The system’s identification of what is an overtaking lane may be determined solely based on
the location of the steering wheel in the vehicl e (left side driver position versus right side
driver position.) If the vehicle is driven to a region where the overtaking lane is on a differ-
ent side from where the vehicle is normally driven, the vehicle may accelerate when the
turn signal lever is operated in the opposite direction to the overtaking lane (e.g., if the
driver normally operates the vehicle in a region where the overtaking lane is to the right but
then drives to a region where the overtaking lane is to the left, the vehicle may accelerate
when the right turn signal is activated).
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 displayed
on the multi-information display. Press the
switch again to deactivate the cruise con-
trol. If the cruise control main switch is pressed
and held for 1.5 seconds or more, the sys-
tem turns on in constant speed control
mode. (

2104-5. Using the driving support systems
1Pressing the cancel switch cancels
the speed control.
The speed control is also canceled when
the brake pedal is depressed.
(When the vehicle has been stopped by
system control, depressing the brake pedal
does not cancel the setting.)
2Pressing the “+RES” switch
resumes the cruise control and
returns vehicle speed to the set
speed.
When your vehicle is too close to a
vehicle ahead, and sufficient automatic
deceleration via the cruise control is
not possible, the display will flash and
the buzzer will sound to alert the
driver. An example of this would be if
another driver cuts in front of you while
you are following a vehicle. Depress
the brake pedal to ensure an appropri-
ate vehicle-to-vehicle distance.
QWarnings may not occur when
In the following instances, warnings
may not occur even when the vehicle-
to-vehicle distance is small.
 When the speed of the preceding
vehicle matches or exceeds your
vehicle speed
 When the preceding vehicle is trav-
eling at an extremely slow speed
 Immediately after the cruise control
speed was set
 When depressing the accelerator
pedal
While driving in vehicle-to-vehicle dis-
tance control mode, this function will
reduce the vehicle speed, if it is deter-
mined to be necessary.
QFunction operation
When the steering wheel begins to be
turned, the vehicle speed will begin
being reduced. When the steering
wheel is returned to the center posi-
tion, the vehicle speed reduction will
end.
