Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system applies the brakes (the stop lights will come on at
this time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the turn signal lever is operated and your vehicle moves to an over-
taking lane while driving at 80 km/h (50 mph) or more, the vehicle will
accelerate to help to overtake a passing vehicle.
The system’s identification of what is an overtaking lane may be 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 from where the
vehicle is normally driven, the vehicle may accelerate when the turn signal
lever is operated in the opposite direction to the overtaking lane (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 system then
returns to constant speed cruising.

Q Automatic cancelation of constant speed control mode
Constant speed control mode is automatically canceled in the following situa-
tions:
O Actual vehicle speed is more than approximately 16 km/h (10 mph) below
the set vehicle speed.
O Actual vehicle speed falls below approximately 30 km/h (20 mph).
O VSC is activated.
O TRC/A-TRC is activated for a period of time.
O When the VSC or TRC/A-TRC system is turned off.
O When the brake control or output restriction control of a driving support sys-
tem operates. (For example: Pre-Coll ision System, Drive-Start Control)
O When the shift lever is in N or the clutch pedal is depressed for a certain
amount of time or more. (Vehicles with manual transmission)
O 4WD models: Switching the transfer mode is not completed within 5 sec-
onds while the cruise control system is on.
If constant speed 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 reliable
repairer.
Q The Dynamic Radar Cruise Control with Road Sign Assist may not oper-
ate properly when
As the Dynamic Radar Cruise Control with Road Sign Assist may not oper-
ate properly in conditions in which RSA may not operate or detect correctly
( P. 299), 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 recog-
nized speed limit by pushing the lever up or down.
O If speed limit information is not available
O When the recognized speed limit is the same as the set speed
O When the recognized speed limit is outside of the speed range that the
dynamic radar cruise control system can operate
Q Brake operation
A brake operation sound may be heard and the brake pedal response may
change, but these are not malfunctions.
Q 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 caution while driving. If a warning message
is shown on the multi-information display, read the message and follow the
instructions. ( P. 271, 575)

A buzzer sounds when the sensors are operating.
QWhen an object is detected to the front or rear of the vehicle
O The buzzer sounds faster as the vehicle approaches an object.
When the vehicle comes within the following distance of the object,
the buzzer beeps continuously.
• Front corner sensor: Approximately 35 cm (1.1 ft.)
• Rear corner sensor: Approximately 40 cm (1.3 ft.)
• Rear center sensor: Approximately 60 cm (2.0 ft.)
O When 2 or more objects are detected simultaneously, the buzzer
system responds to the nearest object.
Approximately 60 cm (24 in.)
Approximately 150 cm (59 in.)
The diagram shows the detection
range of the sensors. Note that the
sensors may not be able to detect
objects that are extremely close to
the vehicle.
The range of the sensors may
change depending on the shape of
the object etc.

When the engine is stopped by the Stop & Start system when the
vehicle is on an incline, when the brake pedal is released, brake force
is temporarily maintained to prevent the vehicle from rolling back-
wards before the engine is restarted and drive force is generated.
When drive force is generated, the maintained brake force is automat-
ically canceled.
O This function operates on flat surfaces as well as steep inclines.
O Sound may be generated from the brake system, but this does not
indicate a malfunction.
O Brake pedal response may change and vibration may occur, but
this does not indicate a malfunction.
Q Points for use
O 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. 220, 223)
O 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.
O Installation and removal of electrical components and wireless devices may
affect the Stop & Start system. Contact any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer for details.
O When stopping the vehicle for a longer period of time, turn the engine switch
to the “LOCK” position*1 or off*2 to stop the engine completely.
O When the engine is restarted by the Stop & Start system, the steering wheel
may temporarily feel heavy.
O 4WD models only: While driving in L4 mode, it is recommended that the
Stop & Start system be canceled because the system may not operate prop-
erly.
