2404-5. Using the driving support systems
■Lane centering function
This function is linked with
dynamic radar cruise control
with full-speed range and pro-
vides the required assistance by
operating the steering wheel to
keep the vehicle in its current
lane.
When dynamic radar cruise control
with full-speed range is not operat-
ing, the lane centering function
does not operate.
In situations where the white (yel-
low) lane lines are difficult to see or
are not visible, such as when in a
traffic jam, this fu nction will operate
to help follow a preceding vehicle
by monitoring the position of the
preceding vehicle.
If the system detects that the steer-
ing wheel has not been operated
for a fixed amount of time or the
steering wheel is not being firmly
gripped, a warning is displayed on the multi-information display and
the function is temporarily can-
celed.
Press the LTA switch to turn the
LTA system on.
The LTA indicator illuminates and a
message is display
ed on the multi-
information display.
Press the LTA switch again to
turn the LTA system off.
When the LTA syste m is turned on
or off, operation of the LTA system
continues in the same condition the
next time the engine is started.

2444-5. Using the driving support systems
■Hands off steering wheel warn-
ing
In the following situations, a warning
message urging the driver to hold
the steering wheel and the symbol
shown in the illustration are dis-
played on the multi-information dis-
play to warn the driver. The warning
stops when the sys tem determines
that the driver holds the steering
wheel. Always keep your hands on
the steering wheel when using this
system, regardless of warnings.
●When the system determines that
the driver is driving without hold-
ing the steering wheel while the
system 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 temporarily can-
celed. This warning also operates in
the same way when the driver con-
tinuously operates the steering
wheel only a small amount.
●When 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 vehicle condition
and road conditions, the warning
may not operate. Also, if the system
determines that the vehicle is driv-
ing around a curv e, warnings will
occur earlier than during straight-
lane driving.
●When the system determines that
the driver is driving without hold- ing the steering wheel while the
steering wheel assi
st of the steer-
ing assist function is operating.
If the driver continues to keep their
hands off of the steering wheel and
the steering wheel assist is operat-
ing, the buzzer sounds and the
driver is warned. Each time the
buzzer sounds, the continuing time
of the buzzer becomes longer.
■Vehicle sway warning function
When the system determines that
the vehicle is swaying while the
vehicle sway warning function is
operating, a buzzer sounds and a
warning message urging the driver
to rest and the sym bol shown in the
illustration are simultaneously dis-
played on the multi-information dis-
play.
Depending on the vehicle and road
conditions, the warning may not
operate.
■Warning message
If the following warning message is
displayed on the multi-information
display and the LT A indicator illumi-
nates in orange, follow the appropri-
ate troubleshooting procedure. Also,
if a different warning message is
displayed, follow the instructions
displayed on the screen.

due to a malfunction in a sensor
other than the front camera. Turn
the LTA system off, wait for a little
while, and then turn the LTA system
back on.
●“LTA Unavailable at Current
Speed”
The function cannot be used as the
vehicle speed exceeds the LTA
operation range. Drive slower.
■Customization
Function settings can be changed.
(  P.94)
*: If equipped
RSA (Road Sign
Assist)*
The RSA system recognizes
specific road signs using
the front camera 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 recog-
nized road signs, it notifies
the driver through a visual
notification and notification
buzzer.
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 replace-
ment for a driver’s own vision and
awareness. Drive safely by
always paying careful attention to
the traffic rules.

●The dynamic radar cruise con-
trol with full-speed range pro-
vides driving assistance to
reduce the driver’s burden.
However, there ar e limitations
to the assistance provided.
Read the following conditions
carefully. Do not overly rely on
this system and always drive
carefully.
• When the sensor may not be correctly detecting the vehicle
ahead: P.257
• Conditions under which the vehicle-to-vehicle distance con-
trol mode may not function cor-
rectly: P.258
●Set the speed appropriately
depending on the speed limit,
traffic flow, road conditions,
weather conditions, etc. The
driver is responsible for check-
ing the set speed.
●Even when the system is func-
tioning normally, the condition
of the preceding vehicle as
detected by the system may dif-
fer from the condition observed
by the driver. Therefore, the
driver must always remain alert,
assess the danger of each situ-
ation and drive safely. Relying
solely on this system or assum-
ing the system ensures safety
while driving can lead to an
accident, resulting in death or
serious injury.
●Switch the dynamic radar cruise
control with full-speed range
setting to off, using the cruise
control main switch when not in
use.

2504-5. Using the driving support systems
WARNING
■Cautions regarding the driv-
ing assist systems
Observe the following precau-
tions, as there are limitations to
the assistance provided by the
system. Failure to do so may
cause an accident resulting in
death or serious injury.
●Assisting the driver to measure
following distance
The dynamic radar cruise control
with full-speed range is only
intended to help the driver in
determining the following distance
between the driver’s own vehicle
and a designated vehicle traveling
ahead. It is not a mechanism that
allows careless or inattentive driv-
ing, and it is not a system that can
assist the driver in low-visibility
conditions.
It is still necessary for driver to
pay close attention to the vehi-
cle’s surroundings.
●Assisting the driver to judge
proper following distance
The dynamic radar cruise control
with full-speed range determines
whether the follo wing distance
between the driver’s own vehicle
and a designated vehicle traveling
ahead is within a set range. It is
not capable of making any other
type of judgement. Therefore, it is
absolutely necessary for the
driver to remain vigilant and to
determine whether or not there is
a possibility of danger in any
given situation.
●Assisting the driver to operate
the vehicle
The dynamic radar cruise control
with full-speed range does not
include functions which will pre-
vent or avoid collisions with vehi-
cles ahead of your vehicle.
Therefore, if there is ever any
possibility of dang er, the driver
must take immediate and direct
control of the vehicle and act
appropriately in order to ensure
the safety of all involved.
■Situations unsuitable for
dynamic radar cruise control
with full-speed range
Do not use dynamic radar cruise
control with full-speed range in
any of the following situations.
Doing so may result in inappropri-
ate speed control and could
cause an accident resulting in
death or serious injury.
●Roads where there are pedes-
trians, cyclists, etc.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as
those covered with rain, ice or
snow
●On steep downhills, or where
there are sudden changes
between sharp up and down
gradients
Vehicle speed may exceed the
set speed when driving down a
steep hill.
●At entrances to freeways and
highways

2514-5. Using the driving support systems

Driving
This mode employs a radar to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, determines the current vehicle-
to-vehicle following distance, and operates to maintain a suitable fol-
lowing distance from the vehicle ahead. The desired vehicle-to- vehi-
cle distance can also be set by operating the vehicle-to-vehicle
distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distanc e may
become shorter.
WARNING
●When weather conditions are
bad enough that they may pre-
vent the sensors from detecting
correctly (fog, snow, sandstorm,
heavy rain, etc.)
●When there is rain, snow, etc.
on the front surface of the radar
or front camera
●In traffic conditions that require
frequent repeated acceleration
and deceleration
●When your vehicle is towing a
trailer or during emergency tow-
ing
●When an approach warning
buzzer is heard often
Driving in vehicle-to-vehicle distance control mode

2524-5. Using the driving support systems
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration crui sing and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected runni ng ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle s peed is nec-
essary, the system applies the brakes (the stop lights will come on at this
time). The system will respond to changes i n the speed of the vehicle
ahead in order to maintain the ve hicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you st ops, your vehicle will also stop (vehicle is
stopped by system control). Afte r 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
control continues to keep your vehicle stopped.
When the turn signal lever is ope rated and your vehicle moves to an over-
taking lane while driving at 50 mph (80 km/h) or more, the vehi cle will accel-
erate to help to overt ake a passing vehicle.
The system’s identifi cation of what is an overtaking lane may be deter-
mined solely based on the location of the steering wheel in the vehicle (left
side driver position versus righ t side driver position.) If the vehicle is driven
to a region where the overtaking lane is on a different side fr om where the
vehicle is normally driven, the v ehicle may accelerate when the turn signal
lever is operated in the opposite direction to the overtaking l ane (e.g., if the
driver normally operates the vehicle in a region where the over taking lane is
to the right but then drives to a region where the overtaking l ane 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 constan t speed cruising.

Your vehicle will also resume
follow-up cruising if the acceler-
ator pedal is depressed after the
vehicle ahead of you starts off.
1Pressing the cancel switch

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 suffi-
cient automatic deceleration via
the cruise control is not possi-
ble, 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 appropriate
vehicle-to-vehicle distance.
■Warnings may not occur
when
In the following instances, warn-
ings may not occur even when
the vehicle-to-vehicle distance is
small.
 When the speed of the pre-
ceding vehicle matches or
exceeds your vehicle speed
 When the preceding vehicle is
traveling at an extremely slow
speed
 Immediately after the cruise
control speed was set
