SLIDING ROOF SYSTEM


  1. SYSTEM CONTROL


    1. The sliding roof system has the following functions:

      Function Outline
      Manual Open-and-close Opens and closes the sliding roof when the open switch or close switch is pressed for less than 0.3 seconds. The sliding roof stops as soon as the switch is released.
      One-touch Auto Open

      • Opens the sliding roof up to the fully opened position when the open switch is pressed for 0.3 seconds or more.

      • To reduce wind noise, this function stops opening the roof at an appropriate stop position. By pressing the open switch once again, the sliding roof can be fully opened.
      One-touch Auto Close Fully closes the sliding roof when the close switch is pressed for 0.3 seconds or more.
      Manual Tilt Up-and-down Tilts the sliding roof up or down when the up switch or down switch is pressed for less than 0.3 seconds. The sliding roof stops as soon as the switch is released.
      One-touch Auto Tilt Up-and-down Fully tilts the sliding roof up or down when the up switch or down switch is pressed for 0.3 seconds or more.
      Jam Protection Automatically stops the sliding roof and opens it almost fully if a foreign object gets jammed in the sliding roof during a close or tilt down operation.
      Key Off Operation Makes it possible to operate the sliding roof for approximately 43 seconds after the engine switch has been turned on (ACC) or off, if the driver or front passenger door is not opened.
      Key-linked Operation*

      • When the driver door key cylinder is turned and held in the unlock position for 1.5 seconds or more, the sliding roof control ECU activates the sliding roof motor to open the sliding roof while the key cylinder is turned.

      • Similarly, turning and holding the driver door key cylinder in the lock position will cause the sliding roof to close.
      Transmitter-linked Operation*

      • When the certification ECU (smart key ECU assembly) receives an unlock signal from the key continuously for 3 seconds or more via the door control receiver, the sliding roof control ECU opens the sliding roof.

      • Similarly, when the certification ECU (smart key ECU assembly) receives a lock signal from the key continuously for 3 seconds or more via the door control receiver, the sliding roof control ECU closes the sliding roof.
      Sliding Roof Open Warning When the engine switch is turned from on (IG) to off and the driver door is opened with the sliding roof open, a warning message appears on the multi-information display, the multi buzzer sounds and the master warning light blinks.

      *: Customizable parameters can be configured through customize settings. For details, refer to the Repair Manual.

    2. Jam Protection Function


      1. To control the jam protection function, the sliding roof ECU monitors the amount of movement and judges jamming of the sliding roof based on the pulse signal from Hall IC and the movement direction of the sliding roof from the magnetic fields.
