Operation of each component
IS300h_EE(OM53B95E)
When riding in an aircraft
When bringing an electronic key onto an aircraft, make sure you do not press any
buttons on the electronic key while inside the aircraft cabin. If you are carrying
an electronic key in your bag etc., ensure that the buttons 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 sound in the cabin when the hybrid
system is stopped. (P. 527)
As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms indi-
cate that the electronic key battery may be depleted. Replace the battery when
necessary. (P. 472)
• The smart entry & start system or the wireless remote control does not oper-
ate.
• 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 1 m (3 ft.)
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
• Table lamps
• Induction cookers
Replacing the battery
P. 472

The number of keys already registered to the vehicle can be confirmed. Ask any
authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional for details.
