Operation of each component
IS300h_EE(OM53D56E)
■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 so und in the cabin when the hybrid system is
stopped. ( →P. 5 4 2 )
●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 8 8 )
• 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 8 8
■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.

NOTICE
■To prevent key damage
●Do not drop the keys, subject them to strong shocks or bend them.
●Do not expose the keys to high temperatures for long periods of time.
●Do not get the keys wet or wash them in an ultrasonic washer etc.
●Do not attach metallic or magnetic materials to the keys or place the keys close to
such materials.
●Do not disassemble the keys.
●Do not attach a sticker or anything else to the surface of the electronic key.

systems and induction cookers, or medical electrical equipment, such as low-fre-
quency therapy equipment.
■Carrying the electronic key on your person
Carry the electronic key 10 cm (3.9 in.) or more away from electric appliances that are
turned on. Radio waves emitted from electric appliances within 10 cm (3.9 in.) of the
electronic key may interfere with the key, causing the key to not function properly.
■In case of a smart entry & start system malfunction or other key-related problems
Take your vehicle with all the electronic keys provided with your vehicle, including the
card key, to any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
