* Brake Pedal: Pressing the brake pedal will immediately disengage the cruise control.
* Clutch Pedal (if manual transmission): Pressing the clutch pedal will disengage the cruise control.
* Throttle Pedal: Pressing the accelerator pedal beyond a certain point will disengage the cruise control.
* Cruise Control Cancel Button: This is typically a button on the steering wheel or a stalk near the steering wheel that specifically cancels cruise control.
Therefore, there's no single switch to find. The system is deactivated through normal vehicle operation. Look for the cruise control cancel button on your steering wheel or its immediate vicinity.
