■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 using the entry function.
●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 surrounding radio
wave conditions. In this case, the key confinement prevention 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.

CAUTION
■Caution while driving
●Keep the trunk lid closed while driving.
If the trunk lid is left open, it may hit near-by objects while driving or luggage in
the trunk may be unexpectedly thrown out, causing an accident.
In addition, exhaust gases may enter the vehicle, causing death or a serious
health hazard. Make sure to close the trunk lid before driving.
●Before driving the vehicle, make sure that the trunk lid is fully closed. If the trunk
lid is not fully closed, it may open unexpectedly while driving, causing an accident.
●Never let anyone sit in the trunk. In the event of sudden braking or a collision, they
are susceptible to death or serious injury.
■When children are in the vehicle
Observe the following precautions.
Failure to do so may result in death or serious injury.
●Do not allow children to enter the trunk.
If a child is accidentally locked in the trunk, they could have heat exhaustion or
suffocate.
●Do not allow a child to open or close the trunk lid.
Doing so may cause the trunk lid to operate unexpectedly, or cause the child’s
hands, head, or neck to be caught by the closing trunk lid.
