AUTO OPERATION

Sunroof and sunshade operates automatically by operating the sunroof switch assembly.

NOTE:

If initialization setting is not performed, the automatic function does not operate.

During automatic operation, when the sunroof switch assembly is operated, automatic operation can be stopped.

ANTI-PINCH FUNCTION

Sunroof motor assembly monitors the sunroof condition using the signals from sunroof motor. When sunroof motor assembly detects an interruption during auto operation (close or tilt down operation), sunroof motor will tilt up or open [145 mm (5.91 in) or more] sunroof.
Sunshade motor assembly monitors the sunshade condition using the signals from sunshade motor. When sunshade motor assembly detects an interruption during auto close operation, sunshade motor will open [145 mm (5.91 in) or more] sunshade.

CAUTION:

There are some small distances immediately before the closed position which cannot be detected.

NOTE:

If initialization setting is not performed, the anti-pinch function does not operate.

When the distance between pinching position and fully-open position is less than 145 mm (5.91 in), sunroof or sunshade reverses to fully-open position.

LIN COMMUNICATION

Sunroof motor assembly, sunshade motor assembly and BCM transmit and receive sunroof motor & sunshade motor malfunction signal and retained power function status signal the LIN communication.

RETAINED POWER FUNCTION

Retained power operation is an additional power supply function that enables sunroof system to operate for 45 seconds after power switch is turned OFF.

Retained power function canceled any of the following conditions is satisfied.

Front door CLOSE (door switch OFF)→OPEN (door switch ON)
When power switch is ON again.
When timer times out. (45 seconds)

REMOTE CONTROL FUNCTION

Sunroof and sunshade open when the unlock button on Intelligent Key is activated and kept pressed for more than for approximately 3 seconds with the power switch OFF.

OPERATION CONDITION

Power switch OFF.
Sunroof motor assembly and sunshade motor assembly initialized condition.

NOTE:

Sunroof and sunshade stops when the following operations are performed.

When the unlock button is released.

When the power switch is switched ON while the sunroof and sunshade opening is operated.

Fail-safe

FAIL-SAFE CONTROL BY SUNROOF MOTOR ASSEMBLY

Sunroof motor assembly switches sunroof operation to fail-safe control when malfunction is detected.

Detected item	Judgment condition	Fail-safe operation	Recovery condition
Non-Initialized condition	When the motor integrated CPU detect sunroof position non-initialized condition	Auto OPEN/CLOSE operation (Anti-pinch) and Tilt UP/Tilt DOWN operation are forbidden	Initialization completed
Thermal protection	When the motor integrated CPU detect temperature increases and exceeds threshold	Sunroof operation is forbidden	Approximately 20 seconds or more passed then operate. (Temperature returns to normal)

FAIL-SAFE CONTROL BY SUNSHADE MOTOR ASSEMBLY

Sunshade motor assembly switches sunshade operation to fail-safe control when malfunction is detected.

Detected item	Judgment condition	Fail-safe operation	Recovery condition
Non-Initialized condition	When the motor integrated CPU detect sunshade position non-initialized condition	Auto OPEN/CLOSE operation (Anti-pinch) is forbidden	Initialization completed
Thermal protection	When the motor integrated CPU detect temperature increases and exceeds threshold	Sunshade operation is forbidden	Approximately 20 seconds or more passed then operate. (Temperature returns to normal)
