■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 surroundings.
  • 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 conditions carefully. Do not overly rely on this system and always drive carefully.

  • When the sensor may not be correctly detecting the vehicle ahead
  • Conditions under which the vehicle-to-vehicle distance control mode may not function correctly
  • 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 preceding vehicle as detected by the system may differ from the condition 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 serious 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 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 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 surroundings.

  • Assisting the driver to judge proper following distance

The dynamic radar cruise control determines whether the following distance 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 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 the safety of all involved.

■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 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 highways
  • 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 frequent repeated acceleration and deceleration
  • During emergency towing
  • When an approach warning buzzer is heard often

    Dynamic radar cruise control

    In vehicle-to-vehicle distance control mode, the vehicle automatically accelerates and decelerates to match the speed changes of the preceding vehicle even if the accelerator pedal is not depressed...

    Driving in vehicle-to-vehicle distance control mode

    This mode employs a radar to detect the presence of vehicles up to approximately 328 ft. (100 m) ahead, determines the current vehicle- to-vehicle following distance, and operates to maintain a suitable following distance from the vehicle ahead...

    Engine immobilizer system

    The vehicle’s keys have built-in transponder chips that prevent the engine from starting if a key has not been previously registered in the vehicle’s on-board computer.

    Never leave the keys inside the vehicle when you leave the vehicle.

    This system is designed to help prevent vehicle theft but does not guarantee absolute security against all vehicle thefts.
