The "MAIN button" on a Honda steering wheel is a specific control, explicitly labeled, that typically serves to activate or deactivate certain driver-assist systems.
On Honda vehicles, particularly those equipped with advanced driver-assist systems (ADAS), the steering wheel houses various controls for convenience and safety features. Among these, the MAIN button plays a crucial role in managing systems like the Lane Keeping Assist System (LKAS) or adaptive cruise control.
Understanding the MAIN Button's Functionality
Based on the provided reference, the MAIN button is directly linked to the control of specific vehicle systems. For instance:
- System Activation/Deactivation: You can press the MAIN button or the LKAS button to turn the system off. This indicates its primary function is to toggle the operational status of a linked feature.
- Association with LKAS: The reference highlights its use with the Lane Keeping Assist System (LKAS), which assists drivers in staying within their lane. While LKAS is designed for convenience, the reference clearly states that it "is not a substitute for your vehicle control" and requires driver engagement ("The system does not work if you take your hands off the steering wheel or fail to steer the vehicle."). The MAIN button provides a quick way to disengage this system when desired.
Common Placement and Related Controls
The MAIN button is usually located on the right side of the steering wheel, often near controls for adaptive cruise control (like SET, RES, and CANCEL) or other driver-assist features. Its presence allows drivers to easily manage these sophisticated systems without taking their hands far from the wheel.
Here's a quick overview of relevant buttons often found on Honda steering wheels:
| Button Name | Common Function | Notes on Usage |
|---|---|---|
| MAIN | Activates/Deactivates core driver-assist systems (e.g., Adaptive Cruise Control, LKAS) | Provides master control for linked features. |
| LKAS | Activates/Deactivates Lane Keeping Assist System | Specifically for lane-keeping assistance. |
| CRUISE | Engages/Disengages Cruise Control | Traditional cruise control activation. |
| SET/- | Sets current speed or decreases speed for cruise control | Part of the cruise control cluster. |
| RES/+ | Resumes set speed or increases speed for cruise control | Part of the cruise control cluster. |
| CANCEL | Disables active cruise control or other temporary functions | Safely stops automatic system control. |
Why is the MAIN Button Important?
The MAIN button is essential for driver control and safety. While driver-assist systems enhance convenience and reduce fatigue, drivers must always maintain full control of their vehicle. The ability to quickly turn these systems on or off via the MAIN button ensures that the driver remains the ultimate authority over the vehicle's operation, especially in situations where automated assistance might not be ideal or desired.
