Toyota Corolla: Dynamic radar cruise control / Selecting constant speed control mode

When constant speed control mode is selected, your vehicle will maintain a set speed without controlling the vehicle-to-vehicle distance. Select this mode only when vehicle-to-vehicle distance control mode does not function correctly due to a dirty radar, etc.

1 With the cruise control off, press and hold the cruise control main switch for 1.5 seconds or more.

Immediately after the switch is pressed, the dynamic radar cruise control indicator will come on. Afterwards, it switches to the cruise control indicator.

Switching to constant speed control mode is only possible when operating the switch with the cruise control off.

2 Accelerate or decelerate, with accelerator pedal operation, to the desired vehicle speed (at or above approximately 20 mph [30 km/h]) and press the “-SET” switch to set the speed.

Cruise control “SET” indicator will come on.

The vehicle speed at the moment the switch is released becomes the set speed.

■Dynamic radar cruise control can be set when

  • Vehicles with a continuously variable transmission: The shift lever is in D.
  • Vehicles with a manual transmission: The shift lever is in range 2nd or higher.
  • Depending on the control mode, this item can be set at the following speeds.
  • Vehicle-to-vehicle distance control mode: Approximately 20 mph (30 km/h) or more
  • Constant speed control mode: Approximately 20 mph (30 km/h) or more

■Accelerating after setting the vehicle speed

The vehicle can accelerate by operating the accelerator pedal. After accelerating, 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 preceding vehicle.

■Shift position selection (vehicles with a manual transmission)

Select a shift position according to the vehicle speed. If the engine speed is too high or too low, control may be automatically canceled.

■Automatic cancelation of vehicle- to-vehicle distance control mode

Vehicle-to-vehicle distance control mode is automatically canceled in the following situations.

  • Actual vehicle speed falls below approximately 16 mph (25 km/h).
  • VSC is activated.
  • TRAC is activated for a period of time.
  • When the VSC or TRAC system is turned off.
  • The sensor cannot detect correctly because it is covered in some way.
  • Pre-collision braking is activated.
  • Vehicles with a manual transmission: When the shift lever is in N or the clutch pedal is depressed for a certain amount of time or more.

If vehicle-to-vehicle distance control mode is automatically canceled for any reasons other than the above, there may be a malfunction in the system. Contact your Toyota dealer.

■Automatic cancelation of constant speed control mode

Constant speed control mode is automatically canceled in the following situations:

  • Actual vehicle speed is more than approximately 10 mph (16 km/h) below the set vehicle speed.
  • Actual vehicle speed falls below approximately 20 mph (30 km/h).
  • VSC is activated.
  • TRAC is activated for a period of time.
  • When the VSC or TRAC system is turned off.
  • Pre-collision braking is activated.
  • Vehicles with a manual transmission: When the shift lever is in N or the clutch pedal is depressed for a certain amount of time or more.

If constant speed control mode is automatically canceled for any reasons other than the above, there may be a malfunction in the system. Contact your Toyota dealer.

■Brake operation

A brake operation sound may be heard and the brake pedal response may change, but these are not malfunctions.

■Warning messages and buzzers for dynamic radar cruise control

Warning messages and buzzers are used to indicate a system malfunction or to inform the driver of the need for caution while driving. If a warning message is shown on the multi-information display, read the message and follow the instructions.

■When the sensor may not be correctly detecting the vehicle ahead

In the case of the following and depending on the conditions, operate the brake pedal when deceleration of the system is insufficient or operate the accelerator pedal when acceleration is required.

As the sensor may not be able to correctly detect these types of vehicles, the approach warning may not be activated.

  • Vehicles that cut in suddenly
  • Vehicles traveling at low speeds
  • Vehicles that are not moving in the same lane
  • Vehicles with small rear ends (trailers with no load on board, etc.)

  • Motorcycles traveling in the same lane
  • When water or snow thrown up by the surrounding vehicles hinders the detecting of the sensor
  • When your vehicle is pointing upwards (caused by a heavy load in the luggage compartment, etc.)

  • Preceding vehicle has an extremely high ground clearance

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

In the case of the following conditions, operate the brake pedal (or accelerator pedal, depending on the situation) as necessary.

As the sensor may not be able to correctly detect vehicles ahead, the system may not operate properly.

  • 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
  • When driving on a road surrounded by a structure, such as in a tunnel or on a bridge
  • While the vehicle speed is decreasing to the set speed after the vehicle accelerates by depressing the accelerator pedal

    Approach warning (vehicle- to-vehicle distance control mode)

    When your vehicle is too close to a vehicle ahead, and suffisufficient automatic deceleration via the cruise control is not possible, the display will flash and the buzzer will sound to alert the driver...

    RSA (Road Sign Assist)

    The RSA system recognizes specific road signs using the front camera to provide information to the driver via the display. If the system judges that the vehicle is being driven over the speed limit, performing prohibited actions, etc...
