key may not be detected correctly and the system may not operate properly.
(The alarm may go off accidentally, or the door lock prevention may not func-
tion.)

near the ground, or in a high place when the doors are locked or
unlocked.
• The electronic key is near the ground or in a high place, or too close to
the rear bumper center when the trunk is unlocked.

the auxiliary box of the driver's side instrument panel or glove box
when the hybrid system is started or "POWER" switch modes are
changed.
As long as the electronic key is within the effective range, the doors may
l
be locked or unlocked by anyone.
l Even if the electronic key is not inside the vehicle, it may be possible to
start the hybrid system if the electronic key is near the window.
