Dynamic radar cruise controlToyota Safety Sense
Dynamic radar cruise controlDynamic radar cruise controlThis dynamic radar cruise control detects the presence of vehicles ahead, determines
the current vehicle-to-vehicle distance, and operates to maintain a suitable distance
from the vehicle ahead. The desired vehicle-to-vehicle distance can be set by operating
the vehicle-to-vehicle distance switch.Use the dynamic radar cruise control only on highways and expressways.Warning:For safe useDriving safely is solely the responsibility of the driver. Do not overly rely on this
system, and pay careful attention to the surrounding conditions in order to ensure
safe driving.The dynamic radar cruise control provides driving assistance to reduce the driver’s
burden. However, there are limitations to the assistance provided.Read the following items carefully. Do not overly rely on this system and always drive
carefully.Conditions under which the system may not operate correctly: Conditions under which the system may not operate correctlySet the speed appropriately according to the speed limit, traffic flow, road conditions,
weather conditions, etc. The driver is responsible for confirming the set speed.Even if the system is operating correctly, the condition of a preceding vehicle as
recognized by the driver and detected by the system may differ. Therefore, it is necessary
for the driver to pay attention, assess risks, and ensure safety. Over-reliance on
this system to drive the vehicle safely may lead to an accident resulting in death
or serious injury.Precautions for the driving assist systemsObserve the following precautions, as there are limitations to the assistance provided
by the system. Over-reliance on this system may lead to an accident resulting in death
or serious injury.Details of support provided for the driver’s visionThe dynamic radar cruise control is only intended to help the driver in determining
the distance between the driver’s own vehicle and a designated preceding vehicle.
It is not a system which allows for careless or inattentive driving, and is not a
system which assists in poor visibility conditions.The driver must pay attention to their surroundings, even when the vehicle stops.Details of support provided for the driver’s judgementThe dynamic radar cruise control determines whether the distance between the driver’s
own vehicle and a designated preceding vehicle 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.Details of support provided for the driver’s operationThe dynamic radar cruise control does not include functions which will prevent or
avoid collisions with vehicles ahead of your vehicle. Therefore, if there is ever
any possibility of danger, the driver must take immediate and direct control of the
vehicle and act appropriately in order to ensure safety.Situations in which the dynamic radar cruise control should not be usedDo not use the dynamic radar cruise control in the following situations. As the system
will not be able to provide appropriate control, using it may lead to an accident
resulting in death or serious injury.Roads where there are pedestrians, cyclists, etc.When driving on a highway or expressway entrance or exitWhen the approach warning sounds frequentlySituations in which the sensors may not operate properly: Situations in which the sensors may not operate properlySituations in which the lane may not be detected: Situations in which the lane may not be detectedBasic functionsConstant speed cruising:When there are no vehicles aheadThe vehicle drives at the speed set by the driver.If the set vehicle speed is exceeded while driving down a hill, the set vehicle speed
display will blink and a buzzer will sound.Deceleration and follow-up cruisingWhen a preceding vehicle driving slower than the
set vehicle speed is detectedWhen a vehicle is detected driving ahead of your vehicle, the vehicle automatically
decelerates and if a greater reduction in vehicle speed is necessary, the brakes are
applied (the stop lights will come on at this time). The vehicle is controlled to
maintain the vehicle-to-vehicle distance set by the driver, in accordance with changes
in the speed of the preceding vehicle. If vehicle deceleration is not sufficient and
the vehicle approaches the vehicle ahead, the approach warning will sound.AccelerationWhen there are no longer any preceding vehicles driving slower than the
set vehicle speedThe vehicle accelerates until the set vehicle speed is reached and then resumes constant
speed cruising.Starting off:If a preceding vehicle stops, the vehicle will also stop (controlled
stop). After the preceding vehicle starts off, pressing the “
RES” switch or depressing the accelerator pedal will resume follow-up cruising (start
off operation). If a start off operation is not performed, the controlled stop will
continue.System ComponentsMulti-information display

Vehicle-to-vehicle distance switchChanging the vehicle-to-vehicle distanceEach time the switch is pressed, the vehicle-to-vehicle distance setting will change
as follows:If a preceding vehicle is detected, the preceding vehicle mark will be displayed.
The actual vehicle-to-vehicle distance varies in accordance with the vehicle speed.
Also, when the vehicle is stopped by system control, it will be stopped at a certain
distance from the preceding vehicle, depending on the situation, regardless of the
setting.Note:Operating conditionsThe shift lever is in D.The desired set speed can be set when the vehicle speed is approximately 20 mph (30
km/h) or more.If the vehicle speed is set while driving at below approximately 20 mph (30 km/h),
the set vehicle speed will be approximately 20 mph (30 km/h).If the vehicle speed is set while driving at a speed that exceeds the system's upper
limit, the set vehicle speed will be the system's upper limit.Accelerating after setting the vehicle speedAs with normal driving, acceleration can be performed by depressing the accelerator
pedal. After accelerating, the vehicle will return to the set vehicle speed. However,
while in vehicle-to-vehicle distance control mode, the vehicle speed may decrease
to below the set vehicle speed in order to maintain the distance from the preceding
vehicle.When the vehicle is stopped by system control during follow-up cruisingWhen the “
+RES” switch is pressed while the vehicle is stopped by system control, if the preceding
vehicle starts off within approximately 3 seconds, follow-up cruising will resume.If the preceding vehicle starts off within approximately 3 seconds of the vehicle
being stopped by system control, follow-up cruising will resume.Automatic cancellation of vehicle-to-vehicle distance control modeIn the following situations, vehicle-to-vehicle distance control mode will be canceled
automatically:When the brake control or output restriction control of a driving support system operates(For
example: Pre-Collision System, drive-start control)When the parking brake has been operatedWhen the vehicle is stopped by system control on a steep inclineWhen any of the following are detected while the vehicle is stopped by system control:The driver’s seat belt is unfastenedThe driver’s door is openedApproximately 3 minutes have elapsed since the vehicle was stoppedThe parking brake may be actived automatically.Situations in which some or all of the functions of the system cannot operate: Situations in which some or all of the functions of the system cannot operateDynamic radar cruise control system warning messages and buzzersFor safe use: For safe usePreceding vehicles that the sensor may not detect correctlyIn the following situations, depending on the conditions, if the system cannot provide
sufficient deceleration or acceleration is necessary, operate the brake pedal or accelerator
pedal.As the sensor may not be able to correctly detect these types of vehicles, the approach
warning (Approach warning) may not operate.When a vehicle cuts in front of your vehicle or changes lanes away from your vehicle
extremely slowly or quicklyWhen changing lanesWhen a preceding vehicle is driving at a low speedWhen a vehicle is stopped in the same lane as the vehicleWhen a motorcycle is traveling in the same lane as the vehicleConditions under which the system may not operate correctlyIn the following situations, operate the brake pedal (or accelerator pedal, depending
on the situation) as necessary.As the sensor may not be able to correctly detect a vehicle, the system may not operate
properly.When a preceding vehicle brakes suddenlyWhen changing lanes at low speeds, such as in a traffic jamWarning buzzers
Approach warningApproach warningApproach warningIn situations where the vehicle approaches a preceding vehicle and the system cannot
provide sufficient deceleration, such as if a vehicle cuts in front of the vehicle,
a warning display will flash and a buzzer will sound to alert the driver. Depress
the brake pedal to ensure appropriate vehicle-to-vehicle distance.Warnings may not occur whenIn the following situations, the warning may not operate even though the vehicle-to-vehicle
distance is short.When the preceding vehicle is traveling at the same speed or faster than your vehicleWhen the preceding vehicle is traveling at an extremely low speedImmediately after the vehicle speed has been setWhen the accelerator pedal is depressedCurve speed reduction functionWhen a curve is detected, the vehicle speed will begin being reduced. When the curve
ends, the vehicle speed reduction will end.Depending on the situation, the vehicle speed will then return to the set vehicle
speed.In situations where vehicle-to-vehicle distance control needs to operate, such as
when a preceding vehicle cuts in front of your vehicle, the curve speed reduction
function will be canceled.Note:Situations in which the curve speed reduction function may not operateIn situations such as the following, the curve speed reduction function may not operate:When the vehicle is being driven around a gentle curveWhen the accelerator pedal is being depressedWhen the vehicle is being driven around an extremely short curveSupport for lane changeIf your vehicle is being driven at approximately 50 mph (80 km/h) or more and a lane
change to the passing lane is performed, when the turn signal lever is operated and
the lane is changed, the vehicle will accelerate up to the set speed to assist in
overtaking.The system’s recognition of which lane is the passing lane may be based solely on
the location of the steering wheel in the vehicle (left-hand drive/right-hand drive).
If the vehicle is driven in a location where the passing lane is on the opposite side
of that where the vehicle was originally sold, the vehicle may accelerate when the
turn signal lever is operated away from the passing lane. (e.g. The vehicle was manufactured
for a right-hand traffic location, but is being driven in a left-hand traffic location.
The vehicle may accelerate when the turn signal lever is operated to the right.)If your vehicle is being driven at approximately 50 mph (80 km/h) or more and the
lane is changed to that with a vehicle traveling slower than your vehicle, when the
turn signal lever is operated the vehicle will gradually decelerate to assist in changing
lanes.Changing Dynamic radar cruise control settingsThe settings of Dynamic radar cruise control can be changed through customize settings.
