Volvo C70 Convertible Top Reset

When the weather is nice and sunny, it is most definitely the perfect time to bring the top of your convertible down. This way, you can actually soak up some sun and enjoy the pleasant weather.

Normally, there are simple ways to get the top down. First, you need to remove any objects from your trunk and roof area. The vehicle must also be on a level and flat surface. Be sure there is ample clearance of 6 feet to overhead objects and stand clear of your vehicle to prevent injury. And most importantly, the trunk should remain closed. 

Next, turn your car on and press down on your brake pedal. Then, press and hold the button on the right on your console Wait for the option that says Roof Open in the display. Once you have selected this option, your roof should retract into the back portion of your car automatically. At this point, you can now take your foot out of the brake and then turn your car off. 

When closing the roof, you only need to press the left button on your console until you see the Roof Closed option in your display. Then, you can close the roof automatically before taking your foot right off the brake and turn your engine off.

However, these operations may not always work as they should. For instance, it may be that the roof is going through some mechanical issues due to water damage, which impacts the roof system’s operation.

Among the most common issues with the Volvo C70 convertible top that will require a reset include:

  • Convertible roof stuck to closed or open
  • Roof needs to be calibrated

  1. Press the 1 or 2 button until the roof failure see manual option is displayed.
  2. Let go of the button gently.
  3. Press and hold the button the second time. After about 5 seconds, you should see the power retractable top will start to move. Keep it pressed until you have seen the top is completely raised.

The movement of the top should briefly stop. Yet, you should continue to hold the button down during the whole operation. You should hear an audible notification that will come during the entire procedure.

  1. I have a 2012 C70. The top is not functioning. When I put the switch in the open position nothing happens and there is nothing on the display. When I put it in the closed position, the display says “Top fully closed.” Could this be a faulty switch?

    • Hi Marc,

      It’s possible that the issue you’re experiencing with your 2012 C70’s convertible top could be related to a faulty switch, but there are other potential causes as well. Here are a few things you can check and consider:

      – Fuse: Check the fuse box to ensure that the fuse for the convertible top system is intact. A blown fuse can prevent the top from functioning properly.

      – Wiring: Inspect the wiring connections related to the convertible top system. Look for any loose or damaged wires that could be causing a disruption in the electrical circuit.

      – Hydraulic Fluid: The convertible top mechanism relies on hydraulic fluid to operate. Make sure the hydraulic fluid level is sufficient and that there are no leaks in the system. Low fluid levels or leaks can prevent the top from moving.

      – Convertible Top Module: There is a module that controls the operation of the convertible top. It’s possible that the module is malfunctioning, which could explain the lack of response when you activate the switch. A diagnostic scan of the vehicle’s electronic systems may be necessary to identify any module-related issues.

      While a faulty switch is a possibility, it would be advisable to have a professional mechanic or a Volvo dealership examine your vehicle to diagnose and fix the problem accurately. They have the specialized knowledge and equipment needed to diagnose issues with the convertible top system and perform any necessary repairs.
