■Battery-saving function
The battery-saving function w
ill be activated in order to prevent the electronic key bat-
tery and the battery from being discharged while the vehicle is not in operation for a long
time.
●In the following situations, the smart acce ss system with push-button start may take
some time to unlock the doors.
• The electronic key has been le ft in an area of approximately 6 ft. (2 m) of the outside
of the vehicle for 10 minutes or longer.
• The smart access system with push-button st art has not been used for 5 days or lon-
ger.
●If the smart access system with push-button start has not been used for 14 days or lon-
ger, the doors cannot be unlocked at any doors except the driver’s door. In this case,
take hold of the driver’s d oor handle, or use the wireless remote control or the mechan-
ical key, to unlock the doors.
■Electronic Key Battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping the elec-
tronic key from re ceiving radio waves.
The smart access system with push-button st art uses weak radio waves. In the following
situations, the communication between the electronic key and the vehicle may be
affected, preventing the smar t access system with push-but ton start, wireless remote
control and engine immobilizer system from operating properly.
(Ways of coping: P. 551)
●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas st ation, radio station, large display, airport or
other facility that generates strong radio wave s or electrical noise
●When the electronic key is in contact with, or is covered by the following metallic
objects
• Portable radio, cellular phone, cordle ss phone or other wireless communication
device
• 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 other wireless keys (that emit radio waves) are being used nearby
Press twice while pressing and holding
. Confirm that the electronic key indica-
tor flashes 4 times.
While the battery-saving mode is set, the smart
access system with push -button start cannot be
used. To cancel the function, press any of the
