6. Operating Instructions
Your Avital 4115L system comes with two 1-button remote controls. The single button on the remote performs multiple functions based on how it is pressed.
6.1 Remote Starting Your Vehicle
- Ensure the vehicle is in Park (automatic transmission) or Neutral with the parking brake engaged (manual transmission, if configured for this).
- Press and hold the button on your 1-button remote control for approximately 3 seconds.
- The vehicle's parking lights will flash, and the engine will start. The vehicle will run for a pre-set duration (typically 10 or 15 minutes).
- To turn off the vehicle remotely, press and hold the button again for approximately 3 seconds.
Note: The remote start function will not engage if the hood is open, the brake pedal is pressed, or the vehicle's check engine light is on.
6.2 Entering the Vehicle After Remote Start
- Unlock the vehicle using your factory remote or key.
- Enter the vehicle. Do NOT press the brake pedal yet.
- Insert your key into the ignition and turn it to the "ON" or "RUN" position (do not turn to "START").
- Press the brake pedal. The remote start system will disengage, and the vehicle will now be operating under key control.
6.3 Remote Control Battery Replacement
When the remote control's range decreases significantly, it may be time to replace the battery. Refer to the remote control's specific instructions for battery type and replacement procedure. Typically, this involves opening the remote casing and replacing a coin-cell battery.
7. Maintenance
The Avital 4115L Avistart Remote Start System is designed for minimal maintenance. Follow these guidelines to ensure longevity:
- Remote Control Care: Keep remote controls dry and avoid dropping them. Replace batteries as needed.
- System Inspection: Periodically have your vehicle's electrical system and the remote start wiring inspected by a qualified technician, especially if you notice any unusual behavior.
- Cleaning: Do not use harsh chemicals to clean the remote controls or any visible components of the system. A soft, damp cloth is sufficient.
8. Troubleshooting
If you experience issues with your Avital 4115L system, consider the following common solutions:
- Remote Start Not Engaging:
- Check if the vehicle is in Park (automatic) or Neutral with the parking brake engaged (manual).
- Ensure all doors, hood, and trunk are closed.
- Verify the remote control battery is not depleted.
- Check if the vehicle's check engine light is on. Some systems prevent remote start under certain fault conditions.
- Reduced Remote Range:
- Replace the remote control battery.
- Ensure there are no large metallic objects or structures blocking the signal between the remote and the vehicle.
- Vehicle Shuts Off After Remote Start:
- Ensure the key is turned to the "ON" or "RUN" position before pressing the brake pedal when entering the vehicle.
- This could indicate an issue with the vehicle's immobilizer bypass module or the system's programming. Professional diagnosis may be required.
For persistent issues, contact a qualified Avital dealer or automotive electronics technician for assistance.
