■Conditions in which the function may not operate or detect correctly
In the following situations, RSA does not operate normally and may not rec-
ognize signs, display the incorrect sign, etc. However, this do es not indicate a
malfunction.
● The front camera is misaligned due to a strong impact being applied to the
sensor, etc.
● Dirt, snow, stickers, etc. are on the windshield 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 incorr ectly.
● If a sign not appropriate for the currently traveled lane, but the 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.
● Side road speed signs may be detected and displayed (if positio ned in sight
of the front camera) while the vehicle is traveling on the main road.
● Roundabout exit road speed signs may be detected and displayed (if posi-
tioned in sight of the front camera) while traveling on a round about.
● The front of the vehicle is raised or lowered due to the carrie d load.
● The surrounding brightness is not sufficient or changes suddenly.
● When a sign intended for trucks, etc. is recognized.
● The navigation system map data is outdated.
● The navigation system is not operating.
● 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 si gn was displayed
on the multi-information display, the same sign displays again when the
engine switch is turned to ON.

Driving
In vehicle-to-vehicle distance control mode, the vehicle automatically
accelerates, decelerates and st ops to match the speed changes o f the
preceding vehicle even if the acc elerator pedal is not depressed. In
constant speed control mode, t he vehicle runs at a fixed speed.
Use the dynamic radar cruise control with full-speed range on f ree-
ways and highways.

2684-5. Using the driving support systems
When the turn signal lever is operated and your vehicle moves to an over-
taking lane while driving at 50 mph (80 km/h) or more, the vehi cle will
accelerate to help to overtake a passing vehicle.
The system’s identification of what is an overtaking lane may b e deter-
mined solely based on the location of the steering wheel in the vehicle (left
side driver position versus right 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 vehicle 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 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 syst em then
returns to constant speed cruising.
Press the cruise control main
switch to activate the cruise
control.
Dynamic radar cruise control indi-
cator will come on and a message
will be displayed on the multi-infor-
mation display.
Press the switch again to deacti-
vate the cruise control.
If the cruise control main switch is pressed and held for 1.5 seconds or
more, the system turns on in constant speed control mode. ( P. 274)
Accelerate or decelerate, with
accelerator pedal operation, to
the desired vehicle speed (at or
above approximately 20 mph
[30 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.

2724-5. Using the driving support systems
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.
■Warnings may not occur when
In the following instances, war nings may not occur even when th e
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
While driving in vehicle-to-vehi cle distance control mode, this function
will reduce the vehicl e speed, if it is determined to be necess ary.
■Function 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 position, the vehicl e speed reduction will end.
Depending on the situat ion, the vehicle speed will then return to the
vehicle-to-vehicle distanc e control mode set speed.
In situations where vehicle-to-v ehicle distance control needs to
operate, such as when a preceding vehicle cuts in front of your
vehicle, the curve speed reduction function will be canceled.

■Automatic cancelation of c onstant speed control mode
Constant speed control mode is automatically canceled in the following situa-
tions:
● Actual vehicle speed is more than approximately 10 mph (16 km/h ) below
the set vehicle speed.
● Actual vehicle speed falls below approximately 20 mph (30 km/h) .
● VSC is activated.
● TRAC is activated for a period of time.
● When the VSC or TRAC system is turned off.
● When the brake control or output restriction control of a driving support sys-
tem operates. (For example: Pre -Collision System, Drive-Start Control)
If constant speed control mode is automatically canceled for any reasons
other than the above, there may be a malfunction in the system. Contact your
Toyota dealer.
■ Situations in which the curve speed reduction function may not operate
In situations such as the following, the curve speed reduction function may
not operate:
● When the vehicle is being driven around a gentle curve
● When the accelerator pedal is being depressed
● When the vehicle is being driven around an extremely short curve
■ Brake operation
A brake operation sound may be heard and the brake pedal response may
change, but these are not malfunctions.
■ Warning messages and buzzers for d ynamic radar cruise control with
full-speed range
Warning messages and buzzers are used to indicate a system malfunction or
to inform the driver of the need for caution while driving. If a warning message
is shown on the multi-information display, read the message and follow the
instructions. ( P. 226, 465)
