●
Operating remote controller trunk switch or trunk lid opener switch (under the driver door armrest) allows
trunk lid auto OPEN operation. Also, operating trunk lid close switch (inside the trunk lid) allows trunk lid
auto CLOSE operation.
●
If any pinched foreign material is detected during auto CLOSE operation, the anti-pinch mechanism stops
trunk lid from closing and shifts the operation to manual.
●
The buzzer sounds when trunk lid auto operation starts (operation start buzzer).
●
The buzzer sounds during trunk lid auto CLOSE operation (warning buzzer).
OPERATING CONDITION
Any of the following operations during trunk lid auto operation stops the auto operation and shifts the operation
to manual. Moving trunk lid manually to a position just before fully closed position activates the auto closure
mechanism to close trunk lid completely.

●
