Battery-saving function
The battery-saving function w ill be activated in order to pr event 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 approximatel y 6 ft. (2 m) of the outside
of the vehicle for 10 minutes or longer.

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 wa ves. 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 sy stem from operating properly.
(Ways of coping: → P. 546)●
When the electronic key battery is depleted ●
Near a TV tower, electric power plant, gas st ation, radio station, la rge display, airport or
other facility that generates strong radio wave s or electrical noise●
When the electronic key is in contact wi th, 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 ●

If the wireless remote control is used to lo ck the doors when the electronic key is near
the vehicle, there is a possibility that the d oor may not be unlocked by the entry func-
tion. (Use the wireless remote control to unlock the doors.) ●
When the lock operation is performed using the lock sensor, recognition signals will be
shown up to two consecutive times. After this, no recognition signals will be given.●
If the door handle becomes wet while the el ectronic key is within the effective range,
the door may lock and unlock repeatedly. In this case, follow th e following correction
procedures to wash the vehicle.

of death or serious injury in the event of an accident.
Adjustments should not be made while drivin g as the seat may unexpectedly move and
cause the driver to lose control of the vehicle. Inner
