Toyota Camry (XV70): Selecting constant speed control mode - Dynamic radar cruise control

Toyota Camry Owner's Manual XV70 (2017-2024) / Driving / Using the driving support systems / Selecting constant speed control mode - Dynamic radar cruise control

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.

Using the driving support systems

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.

Using the driving support systems

■Dynamic radar cruise control can be set when

  • The shift lever is in D.
  • 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.

■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.
  • When the brake control or output restriction control of a driving support system operates. (For example: Pre-Collision System, Drive-Start Control)
  • The parking brake is operated.

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.
  • When the brake control or output restriction control of a driving support system operates. (For example: Pre-Collision System, Drive-Start Control)
  • The parking brake is operated.

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.

■Situations in which the curve speed reduction function may not operate

In situations such as the following, the curve speed reduction function may not operate:

  • When the vehicle is being driven around a gentle curve
  • When the accelerator pedal is being depressed
  • When the vehicle is being driven around an extremely short curve

■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.)

Using the driving support systems

  • 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.)

Using the driving support systems

  • Preceding vehicle has an extremely high ground clearance

Using the driving support systems

■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

Using the driving support systems

  • When steering wheel operation or your position in the lane is unstable

Using the driving support systems

  • 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

■Situations in which the curve speed reduction function may not operate properly

In situations such as the following, the curve speed reduction function may not operate properly:

  • When the vehicle is being driven around a curve on an incline/decline
  • When the course of the vehicle differs from the shape of the curve
  • When the vehicle speed is excessively high when entering a curve
  • When the steering wheel is suddenly operated
