The Kenworth T680 is a workhorse, known for its efficiency and advanced safety features, including its Collision Mitigation System (CMS). While this system is designed to prevent accidents, there might be specific situations where a driver needs to temporarily disable it. Understanding how to do this safely and responsibly is crucial for maintaining control and adapting to challenging road conditions.
Why Would You Even Want to Disable the CMS?
Okay, let's be real. The Collision Mitigation System is there for a reason: safety. It uses radar and cameras to detect potential collisions and can automatically apply the brakes to help avoid or lessen the impact. So, why would anyone want to turn it off? Well, there are a few legitimate scenarios:
- Extremely Inclement Weather: In heavy snow or dense fog, the radar sensors can sometimes get confused, leading to false alerts or unnecessary braking. This can be particularly dangerous on slippery roads, potentially causing the truck to skid or lose control.
- Specific Low-Speed Maneuvers: When navigating tight loading docks or maneuvering in low-speed environments, the CMS might intervene unexpectedly, making precise movements difficult. Imagine trying to back into a tight spot and the brakes suddenly engage because the system thinks you're about to hit something.
- Diagnostic Purposes: Technicians might need to disable the CMS during troubleshooting or repair procedures.
Important Disclaimer: Safety First!
Before we dive into the "how-to," it's absolutely vital to emphasize the importance of safety. Disabling the CMS should only be done when absolutely necessary and when you, the driver, can confidently maintain complete control of the vehicle. Remember, the CMS is a safety net, and removing it increases your responsibility. Always prioritize safe driving practices, maintain a safe following distance, and be extra vigilant when the system is disabled.
Finding the Controls: Where's the Off Switch?
The exact location of the CMS controls can vary slightly depending on the specific Kenworth T680 model year and configuration. However, you'll typically find the relevant controls within the dashboard area, often near the instrument cluster or on the steering wheel.
- Dashboard Controls: Look for buttons or switches labeled "CMS," "Collision Mitigation," "Bendix Wingman Fusion," or similar terms. The specific terminology might vary depending on the system installed in your truck.
- Steering Wheel Controls: Some T680 models have controls integrated into the steering wheel, allowing you to adjust or disable the CMS with a simple button press. Consult your owner's manual to identify the specific controls on your steering wheel.
- Driver Information Display: The driver information display (the screen behind the steering wheel) often provides access to CMS settings. You might be able to navigate through the menus to find options for adjusting the system sensitivity or disabling it altogether.
The Step-by-Step Guide to Disabling the CMS (Temporarily!)
Okay, let's get down to the nitty-gritty. Here’s a general guide, but always refer to your Kenworth T680 owner's manual for the most accurate and model-specific instructions.
- Identify the CMS Controls: As mentioned earlier, locate the relevant buttons, switches, or menu options within the dashboard area, steering wheel, or driver information display.
- Access the CMS Settings: Depending on your truck's configuration, you might need to press a specific button or navigate through the driver information display menus to access the CMS settings.
- Disable the System: Look for an option to "Disable," "Turn Off," or "Deactivate" the Collision Mitigation System. Select this option.
- Confirmation: The system should provide some form of confirmation that the CMS has been disabled. This might be an icon on the driver information display, a message on the screen, or an audible beep.
- Double-Check: Before proceeding, double-check that the CMS is indeed disabled. Review the driver information display and any warning lights to ensure that the system is not active.
A Note About Bendix Wingman Fusion
Many Kenworth T680s are equipped with the Bendix Wingman Fusion system, which integrates various safety features, including collision mitigation, adaptive cruise control, and lane departure warning. Disabling the CMS might also affect other features within the Bendix Wingman Fusion system. Consult your owner's manual for details on how disabling the CMS impacts other functionalities.
Remember to Re-enable the System!
This is crucial! Once the specific situation that required you to disable the CMS has passed (e.g., the heavy snow has stopped, you're no longer maneuvering in a tight space), immediately re-enable the system. The CMS is a vital safety feature, and it should be active whenever possible. Follow the same steps you used to disable the system, but this time, select the option to "Enable," "Turn On," or "Activate" it.
What About Permanent Disablement? (Spoiler: Don't Do It!)
We strongly advise against attempting to permanently disable the CMS. This system is designed to enhance safety and prevent accidents. Permanently disabling it could void your warranty, increase your liability in the event of an accident, and significantly compromise the safety of yourself and others on the road. There are no legitimate reasons to permanently disable the CMS.
Understanding the Potential Consequences
Disabling the CMS, even temporarily, has potential consequences.
- Increased Risk of Accidents: Without the system's intervention, you are solely responsible for preventing collisions. This requires increased vigilance and attention to the road.
- Potential Liability: In the event of an accident, disabling the CMS could be viewed negatively by insurance companies and legal authorities, potentially increasing your liability.
- Warranty Implications: Tampering with or permanently disabling the CMS could void your truck's warranty.
Troubleshooting: What If It Doesn't Work?
If you're having trouble disabling the CMS, here are a few troubleshooting tips:
- Consult the Owner's Manual: The owner's manual is your best resource for detailed instructions and troubleshooting information.
- Check for Error Codes: The driver information display might show error codes related to the CMS. Consult the owner's manual or a qualified technician to interpret these codes.
- Inspect the Sensors: Check the radar sensors (usually located on the front of the truck) for any obstructions, such as dirt, snow, or ice. Clean the sensors if necessary.
- Contact a Kenworth Dealer: If you're still unable to disable the CMS, contact a Kenworth dealer or a qualified technician for assistance.
Frequently Asked Questions
- Can I disable the CMS while driving? Yes, in most cases, you can temporarily disable the CMS while driving, but it's best to do so when safe and practical.
