ITO24P127 277 PRIUS_OM_OM47A17U_DVD_(U) 2-4. Using other driving systems 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 suit- able following distance from the vehicle ahead. Note that vehicle-to-vehicle distance will close in when traveling on long downhill slopes. 278 PRIUS_OM_OM47A17U_DVD_(U) 2 2-4. Using other driving systems Example of constant speed cruising When there are no vehicles ahead The vehicle travels at the speed set by the driver. The desired vehicle-to- vehicle distance can also be set by operating the vehicle-to-vehicle dis- tance control. Example of deceleration cruising When the vehicle ahead is driving slower than the set speed When a vehicle is detected running ahead of you, the system automati- cally 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. Example of follow-up cruising 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 dis- tance set by the driver. Example of acceleration 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. 279 PRIUS_OM_OM47A17U_DVD_(U) 2-4. Using other driving systems Approach warning When your vehicle is too close to a vehicle ahead, and sufficient automatic deceleration via the cruise control is not possible, the dis- play will flash and the buzzer will sound to alert the driver. An exam- ple of this would be if another driver cuts in front of you while you are following a vehicle. Apply the brakes to ensure an appropriate vehi- cle-to-vehicle distance. ■ Warnings may not occur when In the following instances, there is a possibility that the warnings will not occur: ● When the speed of the vehicle ahead matches or exceeds your vehicle speed ● When the vehicle ahead is traveling at an extremely slow speed ● Immediately after the cruise control speed was set ● At the instant the accelerator is applied 280 PRIUS_OM_OM47A17U_DVD_(U) 2 2-4. Using other driving systems Selecting conventional constant speed control mode Constant speed control mode differs from vehicle-to-vehicle distance control mode. When constant speed 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 “ON-OFF” button to activate the cruise control. Press the button again to deacti- vate the cruise control. Switch to constant speed con- trol mode. (Push the lever forward and hold for approximately 1 sec- ond.) Cruise control indicator will come on. When in constant speed control mode, to return to vehicle-to-vehi- cle 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 vehicle-to-vehicle distance con- trol mode. 281 PRIUS_OM_OM47A17U_DVD_(U) 2-4. Using other driving systems If the “POWER” switch is turned off and then turned to ON mode again, the vehicle will automati- cally return to vehicle-to-vehicle distance control mode. Adjusting the speed setting: P. 275 Canceling and speed setting: P. 277 resuming the ■Dynamic radar cruise control can be set when ●The shift position is in D. ●Vehicle speed is above approximately 30 mph (50 km/h). ■Accelerating after setting the vehicle speed 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. ■Set speed The set speed may be unsustainable depending on driving circumstances. 282 PRIUS_OM_OM47A17U_DVD_(U) 2 2-4. Using other driving systems ■Automatic cancelation of vehicle-to-vehicle distance control Vehicle-to-vehicle distance control driving is automatically canceled in the following situations: ●Actual vehicle speed falls below approximately 25 mph (40 km/h). ●Enhanced VSC is activated. ●The sensor cannot operate correctly because it is covered in some way. ●The windshield wipers are operating at high speed (when the wiper switch is set to the high speed windshield wiper operation position). 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. ■Automatic cancelation of constant speed control The cruise control will stop maintaining the vehicle speed in the following sit- uations: ●Actual vehicle speed is more than approximately 10 mph (16 km/h) below the set vehicle speed. At this time, the memorized set speed is not retained. ●Vehicle speed falls below approximately 25 mph (40 km/h). ●Enhanced VSC is activated. 283 PRIUS_OM_OM47A17U_DVD_(U) 2-4. Using other driving systems ■Radar sensor and grille cover Always keep the sensor and grille cover clean to ensure that the vehicle-to- vehicle distance control operates properly. (Some obstructions, such as snow, ice and plastic objects, cannot be detected by the obstruction sensor.) Dynamic radar cruise control (vehicle-to-vehicle distance control mode) will be canceled if dirt is detected. (Constant speed control mode can be used).

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. ■Cautions regarding the driving assist systems Observe the following precautions. 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 determines whether the following dis- tance between the driver’s own vehicle and a designated vehicle traveling ahead is appropriate or not. 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 no capability to prevent or avoid a collision with a vehicle traveling ahead. Therefore, if there is ever any 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. 286 PRIUS_OM_OM47A17U_DVD_(U) 2 2-4. Using other driving systems CAUTION ■To avoid inadvertent cruise control activation Switch the cruise control off using the “ON-OFF” button when not in use. ■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. ●Except on highways or expressways ●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 expressways ●When weather conditions are bad enough that they may prevent the sen- sors from functioning correctly (fog, snow, sandstorm, heavy rain, etc.) ●When an approach warning buzzer is heard often ●During emergency towing 287 PRIUS_OM_OM47A17U_DVD_(U) 2-4. Using other driving systems CAUTION ■When the sensor may not be correctly detecting the vehicle ahead Apply the brakes (or accelerator pedal) as necessary when any of the follow- ing 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 (P. 280) will not be activated, and a fatal or serious accident may result. ●Vehicles that cut in suddenly ●Vehicles traveling at low speeds ●Vehicles that are not moving ●Vehicles with small rear ends (trailers with no load on board etc.) ●Motorcycles traveling in the same lane ●Vehicles splashing up water or snow ■Conditions under which the vehicle-to-vehicle distance control may not function correctly Apply the brakes (or accelerator pedal) as necessary in the following condi- tions as the radar sensor may not be able to correctly detect vehicles ahead, and a fatal or serious accident may result: ●When water or snow thrown up by the surrounding vehicles hinders the functioning of the sensor ●When your vehicle is pointing upwards (caused by a heavy load in the lug- gage compartment etc.) ●When the road curves or when the lanes are narrow ●When steering wheel operation or your position in the lane is unstable ●When the vehicle ahead of you decelerates suddenly 288 PRIUS_OM_OM47A17U_DVD_(U) 2 2-4. Using other driving systems CAUTION ■Handling the radar sensor Observe the following to ensure the cruise control system can function effec- tively. Otherwise, the system may not function correctly and could result in an acci- dent. ●Keep the sensor and grille cover clean at all times. Clean the sensor and grille cover with a soft cloth so you do not mark or damage them. ●Do not subject the sensor or surrounding area to a strong impact. If the sensor moves even slightly off position, the system may become inaccurate or malfunction. If the sensor or surrounding area is subject to a strong impact, always have the area inspected and adjusted by your Toyota dealer.
