Adaptive Cruise

[2 Kids]

I recently bought a 2023 ES 250. The salesman specifically assured me there was a way to turn off the adaptive cruise and use regular cruise control. I trued what he said but it does not work.  Is there a regular cruise option? The owners manual does not say anything about it.

Go back to the dealer and make them show you how it works. Every dealer up here has a demonstration and setup expert. They go through a 1 to 2  hour process with each buyer. They will show you how your car works and preset all of the driver selectable options for you and walk you through how to do it. Well worth the hour or so it takes to see this hands on.

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

Dynamic radar cruise control with full-speed range can be set when

• The shift lever is in D.
• The desired set speed can be set when the vehicle speed is approximately 20 mph (30 km/h) or more. (However, when the vehicle speed is set while driving at below approximately 20 mph [30 km/h], the set speed will be set to approximately 20 mph [30 km/h].)

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.

When the Vehicle Stops while Follow up Cruising

• Pressing the “+RES” switch while the vehicle ahead stops will resume follow-up cruising if the vehicle ahead starts off within approximately 3 seconds after the switch is pressed.
• If the vehicle ahead starts off within 3 seconds after your vehicle stops, follow-up cruising will be resumed.
•  
• Automatic Cancelation of Vehicle-to-Vehicle Distance Control Mode
• Vehicle-to-vehicle distance control mode is automatically canceled in the following situations.
• 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.
• The vehicle is stopped by system control on a steep incline.
  • The following are detected when the vehicle has been stopped by system control:
  • The driver is not wearing a seat belt.
  • The driver’s door is opened.
  • The vehicle has been stopped for about 3 minutes
• If vehicle-to-vehicle distance control mode is automatically canceled for any reasons other than the above, there may be a mal-function in the system. Contact your Lexus 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 Lexus 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.

Typical, new member, one post, never comes back, no thank you for the info. Pretty common pattern on this and other car forums. They wonder why newbies have a hard time getting an answer.
