Dynamic Radar Cruise Control with
Road Sign Assist can be
enabled/disabled in on the
multi-information display. ( →P.361)
When the Dynamic Radar Cruise
Control with Road Sign Assist is
operating, while driving down a hill,
the vehicle speed may exceed the
set speed.
In this case, the displayed set vehi-
cle speed will be highlighted and a
buzzer will sound to alert the driver.
■Dynamic radar cruise control can be set when
●The shift lever is in range 2nd or higher.
●Depending on the control mode, this item can be set at the following
speeds. • Vehicle-to-vehicle distance control mode: Approximately 30 km/h (20
mph) or more
• Constant speed control mode:
Approximately 30 km/h (20 mph) or more
■Accelerating after setting the vehi-cle speed
The vehicle can accelerate by operating the accelerator pedal. After accelerat-ing, the set speed resumes. However,
during vehicle-to-vehicle distance con- trol mode, the vehicle speed may decrease below the set speed in order
to maintain the distance to the preceding vehicle.
■Shift position selection
Select a shift position according to the
vehicle speed. If the engine speed is too high or too low, control may be automat-ically canceled.
■Automatic cancelation of vehicle-
to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the follow-
ing situations.
●Actual vehicle speed falls below
approximately 25 km/h (16 mph).
●VSC is activated.
●TRC is activated for a period of time.
●When the VSC or TRC system is turned off.
●The sensor cannot detect correctly because it is covered in some way.
●Pre-collision braking is activated.
●When the shift lever is in N or the
clutch pedal is depressed for a certain amount of time or more.
●The parking brake is operated.
If vehicle-to-vehicle distance control mode is automatically canceled for any
reasons other than the above, there may be a malfunction in the system. Contact any authorized Toyota retailer
or Toyota authorized repairer, or any reli- able repairer.

■The Dynamic Radar Cruise Control
with Road Sign Assist may not
operate properly when
As the Dynamic Radar Cruise Control
with Road Sign Assist may not operate
properly in conditions in which RSA may
not operate or detect correctly
(→P.194), when using this function,
make sure to check the speed limit sign
displayed.
In the following situations, the set speed
may not be changed to the recognized
speed limit by pressing and holding the
“+RES”/“-SET” switch.
●If speed limit information is not avail-
able
●When the recognized speed limit is
the same as the set speed
●When the recognized speed limit is
outside of the speed range that the
dynamic radar cruise control system
can operate
■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
dynamic radar cruise control
Warning messages and buzzers are
used to indicate a system malfunction or
to inform the driver of the need for cau-
tion while driving. If a warning message
is shown on the multi-information dis-
play, read the message and follow the
instructions. (→P.158, 323)
■When the sensor may not be cor-
rectly detecting the vehicle ahead
In the case of the following and depend-
ing on the conditions, operate the brake
pedal when deceleration of the system
is insufficient or operate the accelerator
pedal when acceleration is required.
As the sensor may not be able to cor-
rectly detect these types of vehicles, the
approach warning (→P.187) may not be
activated.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving in the
same lane
●Vehicles with small rear ends (trailers
with no load on board, etc.)
●Motorcycles traveling in the same lane
●When water or snow thrown up by the
surrounding vehicles hinders the
detecting of the sensor
●When your vehicle is pointing
upwards (caused by a heavy load in
the luggage compartment, etc.)

■Conditions under which the vehi-
cle-to-vehicle distance control
mode may not function correctly
In the case of the following conditions,
operate the brake pedal (or accelerator
pedal, depending on the situation) as
necessary.
As the sensor may not be able to cor-
rectly detect vehicles ahead, the system
may not operate properly.
●When the road curves or when the
lanes are narrow
●When steering wheel operation or
your position in the lane is unstable
●When the vehicle ahead of you decel-
erates suddenly
●When driving on a road surrounded by
a structure, such as in a tunnel or on a
bridge

accelerates by depressing the accel-
erator pedal

4-5. Using the driving support systems
*: If equipped
The RSA system recognizes spe-
cific road signs using the front cam-
era and/or navigation system (when
speed limit information is available)
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.
When the front camera recognizes
a sign and/or information of a sign
is available from the navigation sys-
tem, the sign will be displayed on
the multi-information display.
z When the driving support system
information is selected, a maxi-
mum of 3 signs can be dis-
played. ( →P. 8 6 )
z When a tab other than the driving
support system information is
selected, the following types of
road signs will be displayed.
( →P. 8 6 )
• Speed limit begins/ends sign
• Speed limit related information sign
(Highway, Motorway, Urban area,
Residential area)
• End of prohibition sign
• No-entry sign* (when notification is
necessary)
• Speed limit with supplemental sign
(Ramp way only)
*: For vehicles with navigation system

Summary of function
WARNING
■Before using the RSA
Do not rely solely upon the RSA sys-
tem. 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.

information of the navigation sys-
tem, the no-entry sign flashes
and a buzzer will sound. (For
vehicles with navigation system)

is overtaking when a no overtak-
ing sign is displayed on the multi-

release the clutch pedal. The
engine will stop automatically.
When the engine is stopped by the Stop
& Start system, the Stop & Start indica-
tor will illuminate.
■Restarting the engine
With the shift lever in N, depress
the clutch pedal. The engine will
start automatically.
When the engine starts, the Stop &
Start indicator will turn off.
Press the Stop & Start cancel
switch to disable the Stop & Start
system.

Start system
If the Stop & Start system is disabled
using the Stop & Start cancel switch, it
will be automatically re-enabled once
the engine switch is turned off and then
the engine is started.
■Points for use
●If the engine switch is pressed when
the engine is stopped by the Stop &
Start system, the engine will not be
able to be restarted by the automatic
engine start function. In this case,
restart the engine using the normal
engine starting procedure. (→P.136)
●When the engine is being restarted by
the Stop & Start system, the power
outlets may be temporarily unusable,
but this does not indicate a malfunc-
tion.
Stop & Start system
The Stop & Start system stops
and starts the engine accord-
ing to clutch pedal or shift
lever operation when the vehi-
cle is stopped, such as at a
stoplight, intersection, etc., in
order to improve fuel economy
and reduce noise pollution
caused by the engine idling.
