After the camera sensor recognizes a sign, it is displayed on the multi-informa-
tion display when the vehicle passes the sign.
●When the driving assist system infor-
mation is selected, a maximum of 3
signs can be displayed. (→P. 111)
●When other than the driving assist
system information is selected, a
speed limit sign or an all canceled
sign can be displayed. ( →P. 111)
A no overtaking sign and a speed
limit sign with supplemental mark are
not displayed. However, if signs other
than speed limit signs are recog-
nized, they are mentioned in a stack
under the current speed limit sign.

In the following situations, the RSA system alerts the driver using a warning dis-
play.
●When the vehicle speed exceeds the speed warning threshold applied to the
speed limit of the sign displayed on the multi-information display, the sign
color becomes inverted.
●If it is detected that your vehicle is overtaking when a no overtaking sign is dis-
played on the multi-information display, the sign flashes.
●When the RSA system recognizes a no-entry sign and detects that the vehicle
has entered a no-entry area based on the map information of the navigation
system, the no-entry sign flashes.
■Automatic turn-off of RSA sign display
One or more signs automatically turn off in the following situations.
●A new sign is not recognized for a certain distance.
●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 op erate normally and may not recognize signs,
display the incorrect sign, etc. However, this does not indicate a malfunction.
●The camera sensor is misaligned due to a st rong impact being applied to the sensor,
etc.
●Dirt, snow, stickers, etc., are on the windshield 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, and if an electronic sign, the contrast is poor.
●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 sensor for a short amount of time.
●The driving scene (turning, lane change, etc.) is judged incorrectly.
●Even if it is a sign not appropriate for the currently traveled lane, such a sign exists
directly after a freeway branches, or in an adjacent lane just before merging.
●Stickers are attached to the rear of the preceding vehicle.
●A sign resembling a system compatible sign is recognized.
●The vehicle is driven in a country with a different direction of traffic.
●Side road speed signs may be detected and displayed (if positioned in sight of the cam-
era sensor) while the vehicle is traveling on the main road.
●Roundabout exit road speed signs may be detected and displayed (if positioned in sight
of the camera sensor) while traveling on a roundabout.

GS450h_300h_OM_OM30F00E_(EE)
■When driving vehicle in country with different speed unit
Since RSA recognizes signs based on the set unit of the meter, it is necessary to change
the set unit of the meter. Adjust the set unit of the meter to the speed unit of signs in the
current location. (→P. 585)
■Turning the system on/off
■Speed limit sign display
If the power switch was last turned off while a speed limit sign was displayed on the multi-
information display, the same sign displays again when the power switch is turned to ON
mode.
■Customization
Setting (e.g. speeding warning threshold) can be changed.
(Customizable feature: →P. 5 8 1 )

multi-information display (

range
∗
In vehicle-to-vehicle distance control mode, the vehicle automatically acceler-
ates, 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.
Use the dynamic radar cruise control with full-speed range on freeways and
highways.

Press the “ON/OFF” button to acti-
vate the cruise control.
Radar cruise control indicator will come
on and a message will be displayed on
the multi-information display.
Press the button again to deactivate the
cruise control.
If the “ON/OFF” button is pressed and
held for 1.5 seconds or more, the system
turns on in constant speed control
mode. (→P. 311)
Accelerate or decelerate, with
accelerator pedal operation, to the
desired vehicle speed (above
approximately 50 km/h [30 mph])
and push the lever down to set the
speed.
Cruise control “SET” indicator will come
on.
The vehicle speed at the moment the
lever is released becomes the set speed.
If the lever is operated while the vehi cle speed is below approximately 50 km/h
(30 mph) and a preceding vehicle is pres ent, the set speed will be adjusted to
approximately50 km/h (30 mph).

Pressing the button changes the vehi-
cle-to-vehicle distance as follows:Long
Medium
Short
The vehicle-to-vehicle distance is set
automatically to long mode when the
power switch is turned to ON mode.
If a vehicle is running ahead of you, the pr eceding vehicle mark will also be displayed.
Select a distance from the table below. Note that the distances shown corre-
spond to a vehicle speed of 80 km/h (50 mph). Vehicle-to-vehicle distance
increases/decreases in accordance with vehicle speed. When the vehicle is
stopped by system control, the vehicle-to-vehicle distance will be about 3 m
(10 ft.) to 5 m (16 ft.) regardless of the vehicle-to-vehicle distance setting.
After the vehicle ahead of you starts off,
push the lever up.
Your vehicle will also resume follow-up
cruising if the accelerator pedal is
depressed after the vehicle ahead of
you starts off.

Pulling the lever toward you 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.)
Pushing the lever up 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 40 km/h (25 mph) 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
following a vehicle. Depress the brake
pedal to ensure an appropriate vehicle-
to-vehicle distance.
■Wa r n i n g s m a y n o t o c c u r w h e n
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 traveling at an extremely slow speed
●Immediately after the cruise control speed was set
●When depressing the accelerator pedal
