3. Installation

Installation of the Kufatec Cruise Control System involves replacing the existing control stalk and integrating the new wiring harness into the vehicle's electrical system. Due to the complexity and the requirement for diagnostic activation, professional installation by a qualified technician is highly recommended.

3.1 Key Installation Steps (General Guidance):

1. Disconnect Battery: Always disconnect the vehicle's battery before beginning any electrical work.
2. Access Steering Column: Remove necessary trim panels to gain access to the steering column and existing control stalks.
3. Replace Control Stalk: Carefully remove the original control stalk and install the new Kufatec control stalk.
4. Integrate Wiring Harness: Connect the provided wiring harness according to the vehicle-specific instructions (not included in this general manual, typically provided with the kit or available from Kufatec). This usually involves connecting to the vehicle's ECU and other relevant electrical points.
5. Reassemble: Reinstall all trim panels and reconnect the battery.
6. Diagnostic Activation: After physical installation, the cruise control function must be activated in the engine control unit (ECU) using appropriate diagnostic software (e.g., VCDS). This step is crucial for the system to function correctly.

Warning:

Incorrect installation can lead to vehicle malfunction or damage. If you are not confident in performing the installation, please seek assistance from a professional automotive technician.

4. Operating Instructions

Once installed and activated, the Kufatec Cruise Control System is operated via the control stalk located on the steering column. Familiarize yourself with the stalk's buttons and their functions before driving.

4.1 Basic Operation:

• Activating Cruise Control:
  • Ensure your vehicle is traveling above the minimum speed required for cruise control (typically around 30 km/h or 20 mph).
  • Move the ON/OFF switch on the stalk to the "ON" position.
  • Press the "SET" button when you reach your desired speed. The system will now maintain this speed.
• Increasing Speed: While cruise control is active, push the stalk upwards or press the "SET +" button (if available) to incrementally increase the set speed.
• Decreasing Speed: While cruise control is active, pull the stalk downwards or press the "SET -" button (if available) to incrementally decrease the set speed.
• Resuming Last Set Speed: If cruise control was temporarily deactivated (e.g., by pressing the brake pedal), press the "RES" (Resume) button to return to the previously set speed.
• Deactivating Cruise Control:
  • Press the brake pedal or clutch pedal.
  • Move the ON/OFF switch on the stalk to the "OFF" position.

Safety Precaution:

Only use cruise control when road and traffic conditions permit. Do not use it in heavy traffic, on winding roads, or in adverse weather conditions (rain, snow, ice) where maintaining constant speed may be unsafe.

5. Maintenance

The Kufatec Cruise Control System is designed to be maintenance-free. Regular vehicle maintenance, as recommended by the vehicle manufacturer, will ensure the proper functioning of all related components.

• Keep the control stalk clean and free from debris.
• Ensure all electrical connections remain secure during routine vehicle inspections.

No user-serviceable parts are contained within the cruise control stalk or wiring harness. Any issues should be addressed by a qualified automotive technician.

6. Troubleshooting

If the Kufatec Cruise Control System does not function as expected, consider the following common issues:

• System Not Activating:
  • Verify that the vehicle speed is above the minimum activation threshold.
  • Check if the ON/OFF switch is in the "ON" position.
  • Ensure the system has been correctly activated via diagnostic software in the engine control unit. This is a common reason for non-functionality after installation.
  • Check for any blown fuses related to the cruise control or vehicle's electrical system.
• Intermittent Operation:
  • Inspect wiring connections for looseness or corrosion.
  • Ensure brake light switches and clutch switches are functioning correctly, as these can deactivate cruise control.

For persistent issues, it is recommended to consult a professional automotive technician who can perform a diagnostic scan of the vehicle's systems.
