■Caution for use while driving
●When operating the multi-information
display while driving, pay extra atten-
tion to the safety of the area around the
vehicle.
●Do not look continuously at the
multi-information di splay while driving
as you may fail to see pedestrians,

play
As the engine needs to be running
during setting up the display, ensure that
the vehicle is parked in a place with ade-
quate ventilation. In a closed area such as
a garage, exhaust gases including harm-
ful carbon monoxide (CO) may collect
and enter the vehicle. This may lead to
death or a serious health hazard.

To prevent battery discharge, ensure that
the engine is running while setting up the
display features.

■Card key (if equipped)
●The card key is not waterproof.
●The mechanical key that is stored inside
the card key should be used only if a
problem arises, such as when the card key does not operate properly.
●If it is difficult to take out the mechanical
key, push down the lock release button
using a pen tip etc. If it is still difficult to
pull it out, use a coin etc.
●To store the mechanical key in the card

■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 acci-
dentally. Pressing a button may cause the
electronic key to emit radio waves that
could interfere with the operation of the air-
craft.
■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.)

depleted. Replace the battery when nec-
essary.
• The smart access system with push-but- ton start or the wireless remote control
does not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.

Lexus dealer for details.
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 tem-
