To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get
the electronic key too close to the vehicle when operating the system from
the outside of the vehicle.
Depending on the position and holding condition of the electronic key, the
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.)
n Note for the smart key system
l
Even when the electronic key is within the effective range (detection
areas), the system may not operate properly in the following cases.
• The electronic key is too close to the window or outside door handle,
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 back door is locked or unlocked.
• The electronic key is on the instrument panel, luggage cover, floor or in
the glove box when the hybrid system is started or “POWER” switch
modes are changed.
l As long as the electronic key is within the effective range, the doors may
be locked or unlocked by anyone. However, only the doors detecting the
electronic key can be used to unlock the vehicle.
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.
l When the lock operation is performed using the lock sensor, recognition
signals will be shown up to two consecutive times. After this, no recogni-
tion signals will be given.
l
The doors may unlock or lock if a large amount of water splashes on the
door handle, such as in the rain or in a car wash when the electronic key
is within the effective range. (The doors will automatically be locked after
approximately 60 seconds if the doors are not opened and closed.)
l If the key is kept near the vehicle while it is being washed, water applied
to a door handle may cause the door to lock and unlock repeatedly. In
this event, place the key in a location 6 ft. (2 m) or more from the vehicle,
taking care not to lose the key.
