Before driving
● To reduce key battery depletion when the
electronic key is to not be used for long
periods of time, set the electronic key to
the battery-saving mode. (P.110)
● 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 electronic key battery may be
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.
● To avoid serious deterioration, do not
leave the electronic key within 3 ft. (1 m)
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
● If the electronic key is near the vehicle for
longer than necessary, even if the smart
access system with push-button start is
not used, the key battery may become
depleted faster than normal. When not
using the smart access system with
push-button start, it is recommended not
to stay with the electronic key near the
vehicle longer than necessary.

■ Confirmation of the number of regis-
tered keys
The number of keys already registered to
the vehicle can be confirmed. Ask your
Lexus dealer for details.
■ If “A New Key has been Registered
Contact Your Dealer for Details” is
shown on the multi-information display
This message will be displayed each time
the driver’s door is opened when the doors
are unlocked from the outside for approxi-
mately 10 days after a new electronic key
has been registered.
If this message is displayed but you have not
had a new electronic key registered, ask
your Lexus dealer to check if an unknown
electronic key (other than those in your
possession) has been registered.
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-
peratures 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 keys.
● Do not attach a sticker or anything else
to the surface of the electronic key.
● 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.
■ Carrying the electronic key on your
person
Carry the electronic key 3.9 in. (10 cm)
or more away from electric appliances
that are turned on. Radio waves emitted
from electric appliances within 3.9 in. (10
cm) of the electronic key may interfere
with the key, causing the key to not func-
tion properly.
■ In case of a smart access system with
push-button start malfunction or
other key-related problems
