INFORMATION
If you close the trunk lid while an electronic key is left
in the trunk and all doors are locked, an alarm should
be activated. However, if the electronic key is placed
near the spare tire or at the edge of the trunk, or if the
electronic key is in a metallic bag, the trunk lid might
not be unlocked.
 If you accidentally lock an electronic key in the trunk
when all doors are locked, be aware that anyone can
unlock the trunk by pushing the trunk button.
 Even when the electronic key is outside the trunk, an
alarm still might be activated if the electronic key is
near the trunk. However, if you have the electronic
key, there is no problem.

outside of the vehicle for more than 10 minutes without locking
or unlocking the doors, the entry function is disabled.
If the electronic key does not enter the effective range of the

following:
