MEMORY RESET PROCEDURE
1. Please observe the following instructi ons at confirming the moonroof operation.
NOTE:
Do not disconnect the electronic power while the moonroof is operating or within 5 seconds after the
moonroof stops. (to wipe-out the memory of lid position and operating friction.)
2. Initialization of system should be conducted after the following conditions. • When the moonroof motor is changed.
• When the moonroof does not operate normally. (Incomplete initialization conditions)

quirement

INITIALIZATION PROCEDURE
If the moonroof does not open or clos e automatically, use the following procedure to return moonroof opera-
tion to normal.
NOTE:
If the moonroof switch is released at any time duri ng step 4, the procedure must be started over again. Leave
the ignition switch ON for at least 2 seconds after this procedure.
1. Push the ignition switch to the ON position.
2. Hold the moonroof switch in the tilt up position. Release the switch when the moonroof has reached the
full tilt up position.
3. Hold the moonroof switch in the tilt up position agai n. After a delay, the moonroof will backup. Release the
switch.
4. Within 4 seconds of releasing the switch in step 3, hold the moonroof switch in the tilt up position again.
The moonroof will move from the full tilt-up → slide-close → slide-open → slide-close → tilt-up → slide-
close. Release the switch, initialization is complete if the moonroof operates normally.
ANTI-PINCH FUNCTION
1. Fully open the moonroof to the full open position.
2. Place a piece of wood at the fully closed position.
3. Close the moonroof completely with auto-slide close function.
4. Moonroof should make contact and then tilt up in reverse for 100mm (3.94 in.) (approx.).
CAUTION:
• Do not test the anti-pinch functi on with your hands or other part of body parts because they may be
pinched.
• Depending on environment and drivin g conditions, if a similar impact or load is applied to the moon-
roof it may lower.
• Test the auto-slide operation before inspectio n when the system initialization is performed.
• Perform the initialization proced ure when the auto-slide operation or anti-pinch function does not
operate normally.
