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.) 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. ( P. 495)
● If the battery becomes low, an alarm will sound in the cabin when the
hybrid system stops. (P. 54)
● 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 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 on the instrument panel, luggage cover, floor or in the glove box when the hybrid system is started or “POWER” 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 conditions, 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.
