buttons on the electronic key while inside the aircraft cabin. If you are carry -
ing an electronic key in your bag etc.,
ensure that the buttons are not likely to be pressed accidentally. Pressing a but -

■Electronic key battery depletion
●The standard battery life is 1 to 2
years.
●If the battery becom es low, an alarm
will sound in the cabin and a message will be displayed on the multi-informa -
tion display when the hybrid system
stops.
●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 batter y-saving mode.
( →P.225)

when necessary.
• The smart entry & start system or the wireless remote control does not oper -
ate.

ger that the electro nic key may be dam-
aged, it is recomm ended that replace-
ment is carried ou t by any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.

leave the electronic key within 1 m (3
ft.) of the followi ng electrical appli- ances that produce a magnetic field:
•TVs
• Personal computers • Cellular phones, cordless phones and
battery chargers
• Table lamps • Induction cookers
●If the electronic key is near the vehicle for longer than necessary, even if the
smart entry & star t system is not oper-
ated, the key battery may become depleted faster than normal.
