Before driving
IS250C/350C_U
NOTICE
■To prevent key damage
Observe the following.
●Do not drop the keys, subject them to strong shocks or bend them.
●Do not expose the keys to high temperatures for a long period 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 electronic keys.
●Do not place the keys near objects that produce magnetic fields, such as TVs,
audio systems and induction cookers, or medical electrical equipment, such as
low-frequency therapy equipment.
■Precautions for handling the card keys
●Do not apply excess force when inserting the mechanical key to the card key.
Doing so may damage the card key.
●If the battery or card key terminals get wet, the battery may corrode and the card
key may stop working.
If the key is dropped into water, or if drinking water etc. is spilled on the key,
immediately remove the battery cover and wipe the battery and terminals. (To
remove the battery cover, lightly grasp it and pull.) If the battery is corroded, have
your Lexus dealer replace the battery.
●Do not crush the battery cover or use a screwdriver to remove the battery cover.
Forcibly removing the battery cover may bend or damage the key.
●If the battery cover is frequently removed, the battery cover may become loose.
●When installing the battery, make sure to check the direction of the battery.
Installing the battery in the wrong direction may cause the battery to deplete rap-
idly.
●The surface of the card key may be damaged, or its coating may peel off in the
following situations.
• The card key is carried together with hard objects, such as coins or keys.
• The card key is scraped with a sharp object, such as a tip of mechanical pencil.
• The surface of the card key is wiped with thinners or benzene.

IS250C/350C_U
■Operation signals
A buzzer sounds and the emergency flashers flash to indicate that the doors have
been locked/unlocked. (Locked: Once; Unlocked: Twice)

lowing situations, the communication between the electronic key and the vehicle

●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas station, radio station, large display,
airport or other facility that generates strong radio waves or electrical noise
●When carrying a portable radio, cellular phone, cordless phone or other wire-
less communication devices
●When the electronic key is in contact with, or is covered by the following metal-
lic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
●When multiple electronic keys are in the vicinity
●When another wireless key (that emits radio waves) is being used nearby
●When carrying or using the electronic key together with the following devices
that emit radio waves
• Another vehicle's electronic key or a wireless key that emits radio waves
• Personal computer or personal digital assistant (PDA)
• Digital audio player
• Portable game system
●If window tint with a metallic content or metallic objects are attached to the rear
window
●Immediately after the retractable hardtop is opened or closed
