Steering assist function/lane centering
function
Depending on the vehicle speed, lane
departure situation, ro ad conditions, etc.,
the driver may not feel the function is oper-
ating or the function may not operate at all.■
Lane departure alert function
The warning buzzer may be difficult to hear
due to external noise, audio playback, etc.
Also, it may be difficult to feel steering
wheel vibrations due to the road conditions,
etc. ■
Hands off steering wheel alert
When the system determines that the driver
has removed the hands from the steering
wheel while the steering assist function or
lane centering function is operating, a warn-
ing message is displaye d on the multi-infor-
mation display. If the driver continues to
keep the hands off of the steering wheel, a
warning message is displayed and the func-
tion is temporarily canceled. This alert also
operates in the same way when the driver
continuously operates the steering wheel
only a small amount. However, depending
on the road conditions , etc., the function
may not cancel. ■

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.

248 4-5. Using the driving support systems
LS500h_OM_OM50F42U_(U) 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.86)  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.86)
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. ■

1 Select on of the multi-informa-
tion display ( → P.86)
2 Press on the steering wheel.

Automatic turn-off of RSA sign display
In the following situations, a displayed
speed limit sign will stop being displayed
automatically: ●
A new sign is not recognized for a certain
distance. (When speed limit information
is not available from the navigation sys-
tem)
In the following situations, do not enter, stop
and yield signs will stop being displayed
automatically: ●
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 camera sensor 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 camera sensor. ●
In inclement weather such as heavy rain,
fog, snow or sand storms
●
Light from an oncoming vehicle, the sun,
etc. enters the camera sensor.
●
The sign is dirty, faded, tilted or bent.
●
All or part of the sign is hidden by the
leaves of a tree, a pole, etc.
●
The sign is only visible to the camera sen-
sor for a short amount of time.

speed cruising.
1 Press the cruise control main switch
to activate the cruise control.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 control.
If the cruise control ma in switch is pressed
and held for 1.5 seconds or more, the sys-

accelerator pedal operation, to the
desired vehicle speed (at or above
approximately 30 mph [50 km/h])
and press the “-SET” switch to set
the speed.Cruise control “SET” indicator will come
on.
The vehicle speed at the moment the
switch is released becomes the set speed.
If the switch is operated while the vehicle
speed is below approximately 30 mph (50
km/h) and a preceding vehicle is present,
the set speed will be adjusted to approxi- mately 30 mph (50 km/h).
To change the set speed, operate the
“+RES” or “-SET” switch until the
desired set speed is displayed.
1 Increases the speed (Except when the vehicle has been
stopped by system control in vehi-
cle-to-vehicle distance control mode)
2 Decreases the speed

off, press the “+RES” switch.
Your vehicle will also resume follow-up
cruising if the accelerator pedal is
depressed after the vehicle ahead of
you starts off. 1 Pressing 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.)
2 Pressing the “+RES” switch
resumes the cruise control and
returns vehicle speed to the set
speed. However, when a vehicle ahead is not
detected, cruise control does not resume
when the vehicle speed is approximately
25 mph (40 km/h) or less.
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
