Electronic key battery depletion
●
The standard battery life is 1 to 2 years.
● The battery becomes depleted even if the electronic key is not used
because the key always transmits radio waves. If the smart key system
or the wireless remote control function does not operate, or the detection
area becomes smaller, the battery may be depleted. Replace the battery
when necessary. (

●
If the battery becomes low, an alarm will sound in the cabin when the
engine stops. (

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
• Recharging cellular phones or cordless phones
• Table lamps
■
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.)
■ Note for the smart key system
●
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 trunk is unlocked.
• The electronic key is on the instrument panel, package tray, floor, or in
the auxiliary box of the driver's side instrument panel or glove box
when the engine is started or “ENGINE START STOP” switch modes
are changed.
