systems and contributes to a safe and comfortable driving expe-
rience:
WARNING
■ Toyota Safety Sense
The Toyota Safety Sense is designed to operate under the assumption that
the driver will drive safely, and is designed to help reduce the impact to the
occupants and the vehicle in the case of a collision or assist the driver in
normal driving conditions.
As there is a limit to the degree of recognition accuracy and control perfor-
mance that this system can provide, do not overly rely on this system. The
driver is always responsible for paying attention to the vehicle’s surround-
ings and driving safely.

Dynamic radar cruise control
In vehicle-to-vehicle distance control mode, the vehicle automatically
accelerates and decelerates to match the speed changes of the pre-
ceding vehicle even if the accelerator pedal is not depressed. In con-
stant speed control mode, the vehicle runs at a fixed speed.
Use the dynamic radar cruise control on freeways and highways.

WARNING
■Before using dynamic radar cruise control
Driving safely is the sole responsibility of the driver. Do not rely solely on the
system, and drive safely by always paying careful attention to your sur-
roundings.
The dynamic radar cruise control provides driving assistance to reduce the
driver’s burden. However, there are limitations to the assistance provided.
Set the speed appropriately depending on the speed limit, traffic flow, road
conditions, weather conditions, etc. The driver is responsible for checking
the set speed.
Even when the system is functioning normally, the condition of the preced-
ing vehicle as detected by the system may differ from the condition
observed by the driver. Therefore, t he driver must always remain alert,
assess the danger of each situation and drive safely. Relying on this system
or assuming the system ensures safety while driving can lead to an acci-
dent, resulting in death or serious injury.
■ 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 following 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 care-
less 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 surroundings.
● Assisting the driver to judge proper following distance
The dynamic radar cruise control det ermines whether the following dis-
tance between the driver’s own vehicle 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
vigilant 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 has limited capability to prevent or avoid
a collision with a vehicle traveling ahead. Therefore, if there is ever any
danger, the driver must take immediate and direct control of the vehicle
and act appropriately in order to ens ure the safety of all involved.
■ To avoid inadvertent dynamic radar cruise control activation
Switch the dynamic radar cruise control off using the “ON-OFF” button
when not in use.

WARNING
■Situations unsuitable for dynamic radar cruise control
Do not use dynamic radar cruise control in any of the following situations.
Doing so may result in inappropriate speed control and could cause an acci-
dent 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 highways
● When weather conditions are bad enough that they may prevent the sen-
sors from detecting correctly (fog, snow, sandstorm, heavy rain, etc.)
● When there is rain, snow, etc. on the front surface of the radar sensor or
camera sensor
● In traffic conditions that require frequent repeated acceleration and decel-
eration
● During emergency towing
● When an approach warning buzzer is heard often

Press the “ON-OFF” button 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 button again to deacti-
vate 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. 308)
Accelerate or decelerate, with
accelerator pedal operation, to
the desired vehicle speed (at or
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.

Pulling the lever toward you
cancels the speed control.
The speed control is also canceled
when the brake pedal is
depressed.
Pushing the lever up resumes
the cruise control and returns
vehicle speed to the set speed.
However, 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.
■Warnings may not occur when
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

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 vehicle-to-vehicle distance control mode
does not function correctly due to a dirty radar sensor, etc.
With the cruise control off,
press and hold the “ON-OFF”
button for 1.5 seconds or more.
Immediately after the “ON-OFF”
button is pressed, the dynamic
radar cruise control indicator will
come on. Afterwards, it switches to
the cruise control indicator.
Switching to constant speed con-
trol mode is only possible when
operating the lever with the cruise
control off.
Accelerate or decelerate, with
accelerator pedal operation, to
the desired vehicle speed (at or
above approximately 40 km/h
[25 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.
