When recharging or replacing the ba ttery (vehicles with smart key sys-
tem)
● In some cases, it may not be possible to unlock the doors using the smart
key system when the battery is discharged. Use the wireless remote control
or the mechanical key to lock or unlock the doors.
● The engine may not start on the first attempt after the battery has recharged
but will start normally after the second attempt. This is not a malfunction.
● The engine switch mode is memorized by the vehicle. When the battery is
reconnected, the system will return to the mode it was in before the battery
was discharged. Before disconnecting the battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery dis-
charged, be especially careful when reconnecting the battery.
■ When the battery is removed or discharged
●The power back door (if equipped) must be initialized. ( →P. 123)
● The moon roof (if equipped) must be initialized. ( →P. 162)
● Toyota parking assist monitor (if equipped) must be initialized. (Refer to
“NAVIGATION AND MULTIMEDIA SYSTEM OWNER’S MANUAL”)
● Panoramic view monitor (if equipped) must be initialized. (Refer to “NAVI-
GATION AND MULTIMEDIA SYSTEM OWNER’S MANUAL”)
WARNING
■Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the battery:
● Make sure each jumper cable is connected to the correct terminal and that
it is not unintentionally in contact with any other than the intended terminal.
● Do not allow the other end of the jumper cable connected to the “+” termi-
nal to come into contact with any other parts or metal surfaces in the area,
such as brackets or unpainted metal.
● Do not allow the + and - clamps of the jumper cables to come into contact
with each other.
● Do not smoke, use matches, cigarette lighters or allow open flame near
the battery.
