■When riding in an aircraft
When bringing an electronic key onto an aircraft, make sure you do not press any but- tons on the electronic key while inside the airc raft cabin. If you are carrying an electronic
key in your bag etc., ensure that the button s are not likely to be pressed accidentally.
Pressing a button may cause the electronic key to emit radio waves that could interfere with the operation of the aircraft.
■Electronic key battery depletion
●The standard battery life is 1 to 2 years. (The card key battery life is about a year and a half.)
●If the battery becomes low, an alarm will so und in the cabin when the hybrid system is
stopped. ( P. 606)
●As the electronic key always receives radio waves, the battery will become depleted
even if the electronic key is not used. The following symptoms indicate that the elec-
tronic key battery may be depleted. Replace the battery when necessary. ( P. 549)
• The smart entry & start system or the wi reless remote control does not operate.
• The detection area becomes smaller.
• The LED indicator on the ke y surface does not turn on.
●To avoid serious deterioration, do not leave the electronic key within 1 m (3 ft.) of the
following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, co rdless phones and battery chargers • Recharging cellular phon es or cordless phones
•Table lamps
• Induction cookers
■Replacing the battery
 P. 549
