vehicle speed exceeds the LTA opera-
tion range. Drive slower.
■Customization
Function settings can be changed. (Customizable features: P.358)
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. 1 9 0
• Conditions under which the vehicle- to-vehicle distance control mode may not function correctly: P. 1 9 1
●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.

WARNING
●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
●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
●During emergency towing
●When an approach warning buzzer is heard often

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 (vehicles with manual transmission)
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.
●When the brake control or output restriction control of a driving support
system operates. (For example: Pre- Collision System, Drive-Start Control)
●Vehicles with manual transmission: When the shift lever is in N or the clutch pedal is depressed for a certain
amount of time or more.
