●
The lock sensor may not work properly if it comes into contact with ice,
snow, mud, etc. Clean the lock sensor and attempt to operate it again, or
use the lock sensor on the lower part of the door handle.
● Fingernails may scrape against the door during operation of the door
handle. Be careful not to injure fingernails or damage the surface of the
door.
■ Notes for the unlocking function
● Gripping the door handle when wearing a glove may not unlock the door.
● A sudden approach to the effective range or door handle may prevent the
doors from being unlocked. In this case, return the door handle to the
original position and check that the doors unlock before pulling the door
handle again.
● If there is another electronic key in the detection area, it may take slightly
longer to unlock the doors after the door handle is gripped.
■ When the vehicle is not dr iven for extended periods
To prevent theft of the vehicle, do not leave the electronic key within 6 ft. (2
m) of the vehicle.
■ 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 function may
not operate.)

■Electronic key battery depletion
● The standard battery life is 1 to 2 years.
● As the electronic key always transmits radio waves, the battery will
become depleted even if the electronic key is not used. The following
symptoms indicate that the electronic key battery may be depleted.
Replace the battery when necessary. ( P. 528)
• The smart key system or the wireless remote control does not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
● To avoid serious deterioration, do not leave the electronic key within 3 ft.
(1 m) of the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Glass top ranges
• Table lamps
■ Precautions when disc onnecting the battery
● In some cases, it may not be possible to unlock the doors using the smart
key system immediately after the battery has been disconnected. Use
the wireless remote control or the mechanical key to lock or unlock the
doors.
● The engine may not start on the first attempt after reconnecting the bat-
tery but will start normally after the second attempt. This is not a malfunc-
tion.
● The “ENGINE START STOP” switch mode is memorized by the vehicle.
When the battery is reconnected, the system will return to the mode it
was in before the battery was disconnected. Before disconnecting the
battery, turn the “ENGINE START STOP” switch off.
If you are unsure what mode the “ENGINE START STOP” switch was in
when the battery was disconnected, be especially careful when reconnect-
ing the battery.
