Toyota Sienna 2010-2018 Owners Manual: 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.

Toyota Sienna. Selecting conventional constant speed control mode


  1. Press the “ON-OFF” button to activate the cruise control.

    Press the button again to deactivate the cruise control.

  2. Switch to constant speed control mode.

    (Push the lever forward and hold for approximately one second)

Constant speed control mode indicator will be displayed.

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 switch is turned off and then turned to IGNITION ON mode again, the vehicle will automatically return to vehicle-to-vehicle distance control mode.

Adjusting the speed setting: Canceling and resuming the speed setting:

Dynamic radar cruise control can be set when

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.

Automatic cancelation of vehicle-to-vehicle distance control

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.

Automatic cancelation of constant speed control

The cruise control will stop maintaining the vehicle speed in the following situations.

Radar sensor and grille cover

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

Before using dynamic radar cruise control

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.

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 travelling 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 travelling 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 travelling ahead. Therefore, if there is ever any danger, the driver must take immediate and direct control of the vehicle and act appropriately in order to ensure the safety of all involved.

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 accident resulting in death or serious injury.

  • 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 sensors from functioning correctly (fog, snow, sandstorm, heavy rain, etc.)
  • When an approach warning buzzer is heard often
  • When your vehicle is towing a trailer

When the sensor may not be correctly detecting the vehicle ahead

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.

  • 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

Conditions under which the vehicle-to-vehicle distance control may not function correctly

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:

  • 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 luggage 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

Handling the radar sensor

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.

  • 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 malfunction.

    If the sensor or surrounding area is subject to a strong impact, always have the area inspected and adjusted by a Toyota dealer.

  • Do not disassemble the sensor.
  • Do not attach accessories or stickers to the sensor, grille cover or surrounding area.
  • Do not modify or paint the sensor and grille cover.
  • If the sensor needs to be replaced, contact your Toyota dealer.
