Before driving
long periods of time, set the electronic
key to the battery-saving mode.
(P.125)
● 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.
● You can replace the battery by yourself
(P.499). However, as there is a dan-
ger that the electronic key may be dam-
aged, it is recommended that
replacement is carried out by your Lexus
dealer.
● 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
• 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 vehi-
cle longer than necessary.
■ If a message regarding the state of the
electronic key or engine switch mode,
etc. is shown

sage that prompts the user to confirm the

mode may be shown on the multi-informa-
tion display. In those cases, follow the
instructions on the display immediately.

peratures for long periods of time.
