■When riding in an aircraft
When bringing an electronic key onto an aircraft, make sure you do not press any but- tons on the electronic key while inside the ai rcraft cabin. If you are carrying an electronic
key in your bag etc., ensure that the buttons are not likely to be pressed accidentally. Pressing a button may cause the electronic key to emit radio waves that could interferewith the operation of the aircraft.
■Electronic key battery depletion
●The standard battery life is 1 to 2 years. (The card key battery life is about a year and a half.)
●If the battery becomes low, an alarm will sound in the cabin when the engine is stopped.( P. 615)
●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 elec- tronic key battery may be depleted. Replace the battery when necessary. ( P. 563)
• The smart entry & start system 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 1 m (3 ft.) of thefollowing 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

■Note for the entry function
●Even when the electronic key is within the effective range (detection areas), the system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle, near the ground, or in a high place when the doors are locked or unlocked.• The electronic key is near the ground or in a high place, or too close to the rear
bumper center when the trunk is opened. • The electronic key is on the instrument pa nel, rear package tray or floor, or in the door pockets or glove box when the engine is started or engine switch modes are
changed.
●Do not leave the electronic key on top of th e instrument panel or near the door pockets
when exiting the vehicle. Depending on the radio wave reception conditions, it may be detected by the antenna outside the cabin and the doors will become lockable from the outside, possibly trapping the electronic key inside the vehicle.
●As long as the electronic key is within the effective range, the doors may be locked orunlocked by anyone. However, only the doors detecting the electronic key can be usedto unlock the vehicle.
●Even if the electronic key is not inside the vehicle, it may be possible to start the engine if the electronic key is near the window.
●The doors may unlock or lock if a large amou nt of water splashes on the door handle,
such as in the rain or in a car wash, when th e electronic key is within the effective range. (The doors will automatically be locked after approximately 30 seconds if the doorsare not opened and closed.)
●If the wireless remote control is used to lock the doors when the electronic key is nearthe 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.)
●Touching the door lock or unlock sensor while wearing gloves may prevent lock or unlock operation.
●If the door handle becomes wet while the electronic key is within the effective range,the door may lock and unlock repeatedly. In this case, follow the following correction procedures to wash the vehicle:
• Place the electronic key in a location 2 m (6 ft.) or more away from the vehicle. (Take care to ensure that the key is not stolen.)• Set the electronic key to battery-saving mode to disable the smart entry & start sys-
tem. ( P. 177)
