repeated impacts or vibrations:

ing:
• Wind or the movement of objects such as leaves and insects inside the vehicle
• Ultrasonic waves emitted from devices
such as the intrusion sensors of other vehi-
cles

cle

or clothes hanging on the coat hooks, are in
the vehicle.

Operation of each component
IS200t_EE(OM53D19E)
■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 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 engine is stopped.
( → P. 5 1 9 )
●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. 4 6 6 )
• The smart entry & start 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 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. 4 6 6
■Confirmation of the registered key number
The number of keys already registered to the vehicle can be confirmed. Ask any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped professional for
details.
■If a wrong key is used
The key cylinder rotates freely to isolate inside mechanism.
