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 cond ition of the electronic key, the key may
not be detected correctly and the system may not oper ate properly. (The alarm
may go off accidentally, or the door lock prevention may not function.) ■
Note for the entry function ●
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, floor or in the glove box when
the engine is started or “ENGINE ST ART STOP” switch modes are changed.●
Do not leave the electronic key on top of the instrument panel or near the door
pockets when exiting the vehicle. Depending on the radio wave reception con-
ditions, it may be detected by the antenna outside the cabin and the door will
become lockable from the outside, possibly trapping the electronic key inside
the vehicle. ●
As long as the electronic key is within the effective range, the doors may be
locked or unlocked by anyone. ●
Even if the electronic key is not inside the vehicle, it may be possible to start the
engine if the electronic key is near the window. ●
The doors may unlock if a large amount of water splashes on the door handle,
such as in the rain or in a car wash. (T he doors will automatically be locked after
approximately 60 seconds if the doors are not open ed and closed.)●
Gripping the door handle when wear ing a glove may not unlock the door.●
If the wireless remote control is used to lock the doors when the electronic key
is near the vehicle, there is a possibility that the door may not be unlocked by the
entry function. (Use the wireless remote control to unlock the doors.) ●
A sudden approach to the effective ra nge or door handle operation may pre-
vent the doors from being unlocked. In th is case, return the door handle to the
original position and check that the do ors unlock before pulling the door han-
dle.
