Trunk light
The trunk light turns on when the trunk is opened.
Trunk easy closer (vehicles with power trunk lid)
In the event that the trunk lid is left slightly open, the trunk easy closer will
automatically close it to the fully closed position.
Function to prevent the trunk being locked with the electronic key inside
When all doors are being locked, closing the trunk lid with the electronic
key left inside the trunk will sound an alarm.
In this case, the trunk lid can be opened pressing the trunk release button on
the trunk lid.
Even when the spare electronic key is put in the trunk with all the doors
locked, the key confinement prevention function can be activated so the
trunk can be opened. In order to prevent theft, take all electronic keys with
you when leaving the vehicle.
Even when the electronic key is put in the trunk with all the doors are
locked, the key may not be detected depending on the places and the sur-
rounding radio wave conditions. In this case, the key confinement preven-
tion function cannot be activated, causing the doors to lock when the trunk
is closed. Make sure to check where the key is before closing the trunk.
The key confinement prevention function cannot be activated if any one of
the doors is unlocked. In this case, open the trunk using the trunk opener.
Overload protection function (vehicles with power trunk lid)
The trunk lid will not operate when excessive load is present on the top of the
trunk lid.
Fall-down protection function (vehicles with power trunk lid)
While the trunk lid is opening automatically, applying excessive force to it
will stop the opening operation to prevent the trunk lid from rapidly falling
down.

CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
Before driving
Make sure that the trunk lid is fully closed. If the trunk lid is not fully

luggage in the trunk may be thrown out, causing an accident.
Do not allow children to play in the trunk.
If a child is accidentally locked in the trunk, they could suffer from heat
exhaustion, suffocation or other injuries.
Do not allow a child to open or close the trunk lid.
Doing so may cause the trunk lid to open unexpectedly, or cause the
child’s hands, head, or neck to be caught by the closing trunk lid.
Important points while driving
Never let anyone sit in the trunk. In the event of sudden braking or a colli-
sion, they are susceptible to death or serious injury.

Recorded seat positions can be activated up to 180 seconds after the driver’s
door is opened and another 60 seconds after it is closed again.
Front passenger’s seat:
Recorded seat positions can be activated up to 180 seconds after the front
passenger’s door is opened.
In order to correctly use the driving position memory function
If a seat position is already in the furthest possible position and the seat is
operated in the same direction, the recorded position may be slightly differ-
ent when it is recalled.
Each electronic key (including a card key) can be registered to
recall your preferred driving position.
Registering procedure
Record your driving position to button “1”, “2” or “3” before
performing the following:
Carry only the key you want to register, and then close the
driver’s door.
If 2 or more keys are in the vehicle, the driving position cannot
