WARNING
■Situations unsuitable for dynamic radar cruise control
with full-speed range
Do not use dynamic radar cruise con- trol with full-speed range in any of the
following situations. Doing so may result in inappropriate speed control and could cause an accident resulting
in death or serious injury.
●Roads where there are pedestrians,
cyclists, etc.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as those
covered with rain, ice or snow
●On steep downhills, or where there
are sudden changes between sharp up and down gradients
Vehicle speed may exceed the set
speed when driving down a steep hill.
●At entrances to freeways and high- ways
●When weather conditions are bad enough that they may prevent the
sensors from detecting correctly (fog, snow, sandstorm, heavy rain, etc.)
●When there is rain, snow, etc., on the front surface of the radar or
front camera
●In traffic conditions that require fre-
quent repeated acceleration and deceleration
●When your vehicle is towing a trailer or during emergency towing
●When an approach warning buzzer is heard often

Driving
This mode employs a radar to detect the presence of vehicles up to approx-
imately 100 m (328 ft.) ahead, d etermines the current vehicle-to-vehicle fol-
lowing distance, and operates to maintain a suitable following distance from
the vehicle ahead. The desired vehicle-to-vehicle distance can also be set
by operating the vehicle-to-vehicle distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distanc e may become
shorter.
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 appe ars
When a vehicle is detected running ahead of you, the system automatically deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the sys-
tem applies the brakes (the stop lights will come on at this ti me). The system will
respond to changes in the speed of the vehicle ahead in order t o maintain the vehi-
cle-to-vehicle distance set by the driver. Approach warning war ns you when the sys-
tem cannot decelerate sufficiently to prevent your vehicle from closing in on the
vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also sto p (vehicle is stopped
by system control). After the vehicle ahead starts off, pressin g the “+RES” switch or
depressing the accelerator pedal (start-off operation) will res ume follow-up cruising.
If the start-off operation is not performed, system control con tinues to keep your
vehicle stopped.

1Pressing the cancel switch can-
cels 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.
When your vehicle is too close to a
vehicle ahead, and sufficient auto-
matic 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 follow-
ing a vehicle. Depress the brake
pedal to ensure an appropriate
vehicle-to-vehicle distance.
■Warnings may not occur when
In the following instances, warnings
may not occur even when the vehi-
cle-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 con-
trol speed was set
 When depressing the accelerator
pedal
When constant speed control mode
is selected, your vehicle will main-
tain a set speed without controlling
the vehicle-to-vehicle distance.
Select this mode only when vehi-
cle-to-vehicle distance control
mode does not function correctly
due to a dirty radar, etc.
1 With the cruise control off, press
and hold the cruise control main
switch for 1.5 seconds or more.

tions:
●Actual vehicle speed is more than approximately 16 km/h (10 mph)
below the set vehicle speed.
●Actual vehicle speed falls below
approximately 30 km/h (20 mph).
●VSC is activated.
●TRC is activated for a period of time.
●When the VSC or TRC system is turned off.
●When the brake control or output restriction control of a driving support system operates.
(For example: Pre-Collision System, Drive-Start Control)
●The parking brake is operated.
If constant speed control mode is auto- matically canceled for any reasons other
than the above, there may be a malfunc- tion in the system. Contact any autho-rized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
■The Dynamic Radar Cruise Control with Road Sign Assist may not
operate properly when (if equipped)
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.266), 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 with full-speed range
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.215, 413)
■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.245) 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.)

*: If equipped
In vehicle-to-vehicle distance con-
trol mode, the vehicle automati-
cally accelerates and decelerates
to match the speed changes of the
preceding vehicle even if the accel-
erator pedal is not depressed. In
constant speed control mode, the
vehicle runs at a fixed speed.
Use the dynamic radar cruise con-
trol on freeways and highways.

WARNING
■Before using dynamic radar cruise control
●Driving safely is the sole responsi-bility of the driver. Do not rely solely on the system, and drive safely by
always paying careful attention to your surroundings.
●The dynamic radar cruise control provides driving assistance to
reduce the driver’s burden. How- ever, there are limitations to the assistance provided.
Read the following conditions care-
fully. Do not overly rely on this system
and always drive carefully.
• When the sensor may not be cor- rectly detecting the vehicle ahead:  P.259
• Conditions under which the vehicle- to-vehicle distance control mode may not function correctly: P.260

Driving
WARNING
●Set the speed appropriately depending on the speed limit, traffic
flow, road conditions, weather con- ditions, etc. The driver is responsi-ble for checking the set speed.
●Even when the system is function-ing normally, the condition of the
preceding vehicle as detected by the system may differ from the con-dition observed by the driver.
Therefore, the driver must always remain alert, assess the danger of each situation and drive safely.
Relying solely on this system or assuming the system ensures safety while driving can lead to an
accident, resulting in death or seri- ous injury.
●Switch the dynamic radar cruise control setting to off, using the cruise control main switch when not
in use.
■Cautions regarding the driving
assist systems
Observe the following precautions, as there are limitations to the assistance
provided by the system. Failure to do so may cause an accident resulting in death or serious injury.
●Assisting the driver to measure fol-lowing distance
The dynamic radar cruise control is
only intended to help the driver in
determining the following distance
between the driver’s own vehicle and
a designated vehicle traveling ahead.
It is not a mechanism that allows
careless or inattentive driving, and it
is not a system that can assist the
driver in low-visibility conditions.
It is still necessary for driver to pay
close attention to the vehicle’s sur-
roundings.
●Assisting the driver to judge proper following distance
The dynamic radar cruise control
determines whether the following dis-
tance between the driver’s own vehi-
cle and a designated vehicle traveling
ahead is within a set range. It is not
capable of making any other type of
judgement. Therefore, it is absolutely
necessary for the driver to remain vig-
ilant and to determine whether or not
there is a possibility of danger in any
given situation.
●Assisting the driver to operate the vehicle
The dynamic radar cruise control
does not include functions which will
prevent or avoid collisions with vehi-
cles ahead of your vehicle. Therefore,
if there is ever any possibility of dan-
ger, the driver must take immediate
and direct control of the vehicle and
act appropriately in order to ensure
the safety of all involved.
■Situations unsuitable for
dynamic radar cruise control
Do not use dynamic radar cruise con- trol in any of the following situations.
Doing so may result in inappropriate speed control and could cause an accident resulting in death or serious
injury.
●Roads where there are pedestrians,
cyclists, etc.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as those
covered with rain, ice or snow

When a vehicle is detected running ahead of you, the system automatically deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the sys-

When the turn signal lever is operated and your vehicle moves t o an overtaking lane
while driving at 80 km/h (50 mph) or more, the vehicle will acc elerate to help to over-
take a passing vehicle.
The system’s identification of what is an overtaking lane may b e determined solely
based on the location of the steering wheel in the vehicle (lef t side driver position
versus right side driver position.) If the vehicle is driven to a region where the over-
taking lane is on a different side from where the vehicle is no rmally driven, the vehi-
cle may accelerate when the turn signal lever is operated in th e 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 over-
taking lane is to the left, the vehicle may accelerate when the right turn signal is acti-
vated).
Example of acceleration
When there are no longer any preceding vehicles driving slower than the
