Dynamic radar cruise control supplements conventional cruise control with a vehicle-to-vehicle distance control. In vehicle-to-vehicle distance control mode, the vehicle automatically accelerates or decelerates in order to maintain a set following distance from vehicles ahead.
*: If equipped
Press the “ON-OFF” button to activate the cruise control.
Dynamic radar cruise control indicator will come on.
Press the button again to deactivate the cruise control.
Accelerate or decelerate the vehicle to the desired speed, and push the lever down to set the speed.
“SET” indicator will come on.
The vehicle speed at the moment the lever is released becomes the set speed.
To change the set speed, operate the lever until the desired set speed is displayed.
Fine adjustment: Momentarily move the lever in the desired direction.
Large adjustment: Hold the lever in the desired direction.
In the vehicle-to-vehicle distance control mode, the set speed will be increased or decreased as follows:
Fine adjustment: By approximately 5 mph (8 km/h) each time the lever is operated Large adjustment: By approximately 5 mph (8 km/h) for each 0.75 seconds the lever is held
Fine adjustment: By approximately 3.1 mph (5 km/h) each time the lever is operated Large adjustment: By approximately 3.1 mph (5 km/h) for each 0.75 seconds the lever is held In the constant speed control mode , the set speed will be increased or decreased as follows: Fine adjustment: By approximately 1 mph (1.6 km/h) each time the lever is operated Large adjustment: The set speed can be increased or decreased continually until the lever is released
Pressing the button changes the vehicle-to-vehicle distance as follows:
The vehicle-to-vehicle distance is set automatically to long mode when the “ENGINE START STOP” switch is turned to IGNITION ON mode.
If a vehicle is running ahead of you, the preceding vehicle mark will also be displayed.
Select a distance from the table below. Note that the distances shown correspond to a vehicle speed of 50 mph (80 km/h). Vehicle- to-vehicle distance increases/decreases in accordance with vehicle speed
The speed setting is also canceled when the brakes are applied.
Resuming is available when the vehicle speed is more than approximately 25 mph (40 km/h).
Driving in vehicle-to-vehicle distance control mode
This mode employs a radar sensor to detect the presence of vehicles up to approximately 400 ft. (120 m) ahead, determines the current vehicle-to-vehicle following distance, and operates to maintain a suitable following distance from the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on long downhill slopes.
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-tovehicle distance can also be set by operating the vehicle-to-vehicle distance control.
When the vehicle ahead is driving slower than the set speed
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. A warning tone warns you when the system cannot decelerate sufficiently to prevent your vehicle from closing in on the vehicle ahead.
When following a vehicle driving slower than the set speed
The system continues follow-up cruising while adjusting for changes in the speed of the vehicle ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
When there are no longer any vehicles ahead driving slower than the set speed
The system accelerates until the set speed is reached. The system then returns to constant speed cruising.
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. Apply the brakes to ensure appropriate vehicleto- vehicle distance.
In the following instances, there is a possibility that the warnings will not occur:
Selecting conventional constant speed control mode
Constant speed control mode differs from vehicle-to-vehicle distance control mode. When constant speed control mode is selected, your vehicle will maintain a set speed regardless of whether or not there are other vehicles in the lane ahead.
Press the button again to deactivate the cruise control.
Cruise control indicator will come on.
When in constant speed control mode, to return to vehicle-to-vehicle distance control mode, push the lever forward again and hold for approximately 1 second.
After the desired speed has been set, it is not possible to return to vehicleto- vehicle distance control mode.
If the “ENGINE START STOP” switch is turned off and then turned to IGNITION ON mode again, the vehicle will automatically return to vehicleto- vehicle distance control mode.
Adjusting the speed setting: Canceling and resuming the speed setting:
The vehicle can accelerate normally. After acceleration, the set speed resumes.
However, during vehicle-to-vehicle distance control mode, the vehicle speed may decrease below the set speed in order to maintain the distance to the vehicle ahead.
Vehicle-to-vehicle distance control driving is automatically canceled in the following situations:
If vehicle-to-vehicle distance control driving is automatically canceled for any other reason, there may be a malfunction in the system. Contact your Toyota dealer.
The cruise control will stop maintaining the vehicle speed in the following situations:
At this time, the memorized set speed is not retained.
Always keep the sensor and grille cover clean to ensure that the vehicle-tovehicle distance control operates properly. (Some obstructions, such as snow, ice and plastic objects, cannot be detected by the obstruction sensor.) Dynamic radar cruise control is canceled if an obstruction is detected.
Warning messages and buzzers are used to indicate a system malfunction or to inform the driver of the need for caution while driving.
FCC ID: HYQDNMWR005
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
Radiofrequency radiation exposure Information: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
This equipment should be installed and operated with minimum distance of 20 cm between the radiator (antenna) and your body.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
Do not overly rely on vehicle-to-vehicle distance control.
Be aware of the set speed. If automatic deceleration/acceleration is not appropriate, adjust the vehicle speed, as well as the distance between your vehicle and vehicles ahead by applying the brakes, etc.
Observe the following precautions.
Failure to do so may cause an accident resulting in death or serious injury.
Switch the cruise control off using the “ON-OFF” button when not in use.
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 accident resulting in death or serious injury.
Vehicle speed may exceed the set speed when driving down a steep hill.
Apply the brakes as necessary when any of the following types of vehicles are in front of you.
As the sensor may not be able to correctly detect these types of vehicles, the approach warning will not be activated, and a fatal or serious accident may result:
Apply the brakes as necessary in the following conditions as the radar sensor may not be able to correctly detect vehicles ahead, and a fatal or serious accident may result:
Observe the following to ensure the cruise control system can function effectively.
Otherwise, the system may not function correctly and could result in an accident.
