LTA (Lane Tracing Assist)
While driving on a road with clear
white (yellow) lane lines, the LTA
system warns the driver if the vehi-
cle may deviate from the current
lane or course
*
, and also can
slightly operate the steering wheel
to help avoid deviation from the
lane or course
*
. Also, while the
dynamic radar cruise control with
full-speed range is operating, this
system will operate the steering
wheel to maintain the vehicle’s lane
position.
The LTA system recognizes white
(yellow) lane lines or a course
*
using the front camera. Addition-
ally, it detects preceding vehicles
using the front camera and radar.
*
: Boundary between asphalt and the
side of the road, such as grass, soil, or
a curb
WARNING

If signs other than speed limit signs are
recognized, they will be displayed in an
overlapping stack under the current
speed limit sign.
The following types of road signs,
including electronic signs and blinking
signs, are recognized.

RSA (Road Sign Assist)
*
The RSA system recognizes spe-
cific road signs using the front cam-
era 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
■
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.

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
that your vehicle has entered a no-
entry area, the displayed sign will
flash and a buzzer will sound.
Depending on the situation, a notifica-
tion function may not operate properly.

Automatic turn-off of RSA sign display
In the following situations, a displayed
speed limit sign and/or do not enter sign
will stop being displayed automatically:
●
No sign has been recognized for a cer-
tain distance.
●
The road changes due to a left or right
turn, etc.
In the following situations, stop and yield
signs will stop being displayed automati-
cally:
●
The system determines that your vehicle
has passed the sign.
●
The road changes due to a left or right
turn, etc.
■
Conditions in which the function may
not operate or detect correctly
In the following situations, RSA does not
operate normally and may not recognize
signs, display the incorrect sign, etc. How-
ever, this does not indicate a malfunction.
●
The front camera is misaligned due to a
strong impact being applied to the sen-
sor, etc.
●
Dirt, snow, stickers, etc. are on the wind-
shield near the front camera.
●
In inclement weather such as heavy rain,
fog, snow or sand storms.
●
Light from an oncoming vehicle, the sun,
etc. enters the front camera.
●
The sign is dirty, faded, tilted or bent.
●
The contrast of electronic sign is low.
●
All or part of the sign is hidden by the
leaves of a tree, a pole, etc.
●
The sign is only visible to the front camera
for a short amount of time.
●
The driving scene (turning, lane change,
etc.) is judged incorrectly.

Stickers are attached to the rear of the
preceding vehicle.
●
A sign resembling a system compatible
sign is recognized.
●
Side road speed signs may be detected
and displayed (if positioned in sight of the
front camera) while the vehicle is travel-
ing on the main road.
●
Roundabout exit road speed signs may
be detected and displayed (if positioned
in sight of the front camera) while travel-
ing on a roundabout.
●
The front of the vehicle is raised or low-
ered due to the carried load.
●
The surrounding brightness is not suffi-
cient or changes suddenly.
●
When a sign intended for trucks, etc. is
recognized.
●
The speed information displayed on the
meter and on the navigation system may
be different due to the navigation system
using map data.

Speed limit sign display
If the engine switch was last turned off while
a speed limit sign was displayed on the
multi-information display, the same sign dis-
plays again when the engine switch is
turned to ON.

trol with full-speed range
In vehicle-to-vehicle distance con-
trol mode, the vehicle automati-
cally accelerates, decelerates and
stops to match the speed changes
of the preceding vehicle even if the
accelerator pedal is not depressed.
In constant speed control mode,
the vehicle runs at a fixed speed.
