KEYS AND DOORS
26The doors cannot be locked using the smart key system
in the following conditions:

Key reminder alarm
If you push the lock button on the outside door handle
with a smart key left in the vehicle, an alarm sounds for 2
seconds and the doors will not lock.
Before you push the lock button, make sure you are carrying
the smart key.
INFORMATION
 Do not put a smart key on the instrument panel, rear
package tray or floor, or in the glove box or auxiliary
box near the selector lever, which falls outside of the
effective range of the smart key system. As the alarm
does not sound when a key is left in such a place, you
might accidentally lock the doors by pushing the lock
button on the outside door handle and be locked out
of the vehicle. Be sure to take the smart key with you.
 If you have the smart key but bring it very close to the
window or outside door handle, the alarm might
activate. In this case, keep the smart key a certain
distance away from the window or outside door
handle and then push the lock button again.
 If the smart key is left in the vehicle, attempting to
lock the door by pushing in the button located in the
inside door handle and holding up the outside door
handle will unlock all the doors and activate the alarm
for 2 seconds.

Key reminder alarm
If you lock your key in the trunk, an alarm sounds for 10
seconds to remind you that the key is in the trunk.
To stop the alarm, push the trunk button. At this time, the trunk
lid is unlocked. Even after the alarm stops sounding, pushing
the trunk button will unlock the trunk lid.

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