The quickest way to disable adaptive cruise control

To turn off adaptive cruise control on your Lexus RX 350, press the CANCEL button on the left side of your steering wheel, or tap the brake pedal. Both methods stop the system when ready. The CANCEL button is the fastest option if you want to keep your hands on the wheel — it's the button with a diagonal line through a circle, located on the stalk below the cruise control lever.

If you want to turn off the system entirely rather than just pause it for one drive, you can disable it through the vehicle settings. This prevents adaptive cruise control from activating when you use the cruise control lever, though the lever itself remains functional for regular cruise control.

Key Takeaways

  • Press CANCEL on the steering wheel stalk or tap the brake pedal to stop adaptive cruise control when ready during a drive.
  • The CANCEL button is located on the left side of the steering wheel, below the cruise control lever.
  • You can permanently disable adaptive cruise control through the vehicle's multi-information display settings without affecting regular cruise control.
  • Tapping the brake pedal disables the system for that drive only; the next time you start the vehicle, the setting returns to your previous preference.

Stopping adaptive cruise control during a drive

When adaptive cruise control is active and you want to stop it when ready, you have two options. The first is to press the CANCEL button on your steering wheel stalk — it's the button with a circle and diagonal line symbol. This is the preferred method because you don't have to remove your foot from the accelerator or brake.

The second option is to tap the brake pedal. Any pressure on the brake will disengage adaptive cruise control right away. This method works if you're uncomfortable reaching for the CANCEL button or if you need to slow down anyway. Note that tapping the brake only stops the system for that moment; it doesn't change your settings for future drives.

Finding the adaptive cruise control settings in your RX 350

To turn off adaptive cruise control at the settings level, start with your vehicle running and the ignition in the ON position. Look at the multi-information display in your instrument cluster — this is the screen between your speedometer and tachometer. On the steering wheel, you'll find buttons labeled with up and down arrows; use these to navigate the menu.

Press the down arrow button repeatedly until you see "Vehicle Settings" or "Driver information Settings" on the display. The exact menu name varies slightly depending on your model year, but it will be in this general area. Once you find it, press the center button or the right arrow to enter that menu.

Disabling adaptive cruise control through the menu

After you enter the Vehicle Settings or Driver information Settings menu, look for an option labeled "Adaptive Cruise Control," "ACC," or "Pre-Collision System." These names refer to the same feature. Use the up and down arrow buttons to highlight the option, then press the center button to open it.

You should see a toggle or on/off setting. Press the center button again to switch it from ON to OFF. The display will confirm the change. Once you've turned it off, press the back button or navigate away from the menu. Your adaptive cruise control will now remain off until you turn it back on through the same process.

If you can't find this option in the main settings, check under "Safety Features" or "Convenience Features" — different model years organize these menus differently. Your owner's manual will show the exact path for your specific year and trim level.

What happens when you disable adaptive cruise control

When you turn off adaptive cruise control through the settings, your regular cruise control still works normally. You can still use the cruise control lever to set a steady speed. The difference is that the system will no longer automatically adjust your speed based on the distance to the car ahead of you.

Disabling it through settings is permanent until you turn it back on. This is different from pressing CANCEL or tapping the brake, which only pauses the system for that drive. If you disable it and then start your vehicle the next day, it will remain off unless you go back into the settings and turn it on again.

Common mistakes when trying to turn off adaptive cruise control

The most common mistake is pressing the cruise control lever itself instead of the CANCEL button. The lever controls whether cruise control is on or off, but it doesn't specifically disable adaptive cruise control — it just pauses the system. If you want to fully turn off the feature, you need to either press CANCEL or change the settings.

Another mistake is confusing the CANCEL button with other buttons on the steering wheel stalk. The CANCEL button has a specific symbol: a circle with a diagonal line through it. It's always on the left side of the wheel, below the main cruise control lever. If you press a different button, you might set up a different feature instead.

Some drivers also assume that turning off adaptive cruise control will turn off regular cruise control too. It won't. You can have regular cruise control on while adaptive cruise control is off, or you can have both on. They're separate systems that work together when both are enabled.

Frequently Asked Questions

Does pressing the brake pedal turn off adaptive cruise control permanently?

No. Pressing the brake pedal stops adaptive cruise control for that moment only. The next time you start your RX 350, the system will return to whatever setting you had before. If you want to permanently disable it, you need to go through the vehicle settings menu.

Can I turn off adaptive cruise control without turning off regular cruise control?

Yes. Regular cruise control and adaptive cruise control are separate features. You can disable adaptive cruise control through the settings while keeping regular cruise control available. When you use the cruise control lever, it will only maintain a set speed without adjusting for traffic ahead.

What's the difference between CANCEL and the cruise control lever?

The CANCEL button stops the system when ready but doesn't change your settings. The cruise control lever turns the entire cruise control system on or off. If you want adaptive cruise control off for all future drives, use the settings menu instead of either button.

Where exactly is the CANCEL button on the steering wheel?

The CANCEL button is on the left side of your steering wheel, on the stalk below the main cruise control lever. It has a symbol of a circle with a diagonal line through it. It's the easiest way to stop adaptive cruise control while driving without using the brake pedal.

Will disabling adaptive cruise control affect my vehicle's safety features?

Disabling adaptive cruise control only turns off that specific feature. Other safety systems like pre-collision warnings and automatic emergency braking remain active. These are separate systems that work independently of adaptive cruise control.
