AUTO TRUNK SYSTEM

AUTO TRUNK SYSTEM

Outline of System

EIS0055K

●

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.

●

When trunk lid opener switch is operated.

●

When trunk lid close switch is operated.

●

When remote control trunk opening switch is operated (at least 0.5 seconds).

●

When selector lever is shifted to a position other than “P” position (detention switch: ON).

●

When vehicle speed becomes 7 km/h or higher.

●

When auto operation does not end after 10 seconds since the start.

●

With trunk lid position falls within ranges A and B in the figure,
when trunk lid stops auto operation forcefully or because of
pinched foreign material.

Removal and Installation

EIS0055L

PRECAUTIONS FOR WORK

●

During removal and installation, be careful not to allow any
grease to adhere to the solenoid clutch joint (A in the figure).

●

If grease adheres to the solenoid clutch joint (A in the figure),
clutch becomes slippery and generates a transmission loss
resulting in inactive auto operation.
