facturer.
●Dispose of used batteries according to local laws.

function properly.
●The operational range will be reduced.

5327-2. Steps to take in an emergency
CAMRY_U (01999-06122)■When recharging or replacing the battery (vehicles with a 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 exchanging the battery
●Use a battery that conforms to European regulations.
●Use a battery that the case size is same as the previous one (LN3), 20 hour
rate capacity (20HR) is equivalent (70Ah) or greater, and performance rating
(CCA) is equivalent (600A) or greater.
• If the sizes differ, the battery cannot be properly secured.
• If the 20 hour rate capacity is low, even if the time period where the vehi-
cle is not used is a short time, the battery may discharge and the engine
may not be able to start.
●For details, consult your Toyota dealer.
