5028-2. Steps to take in an emergency
AYGO_OM_Europe_OM9A012E
■ Precautions when the battery is discharged (vehicles with a smart entry
& start system)
● In some cases, it may not be possible to unlock the doors using the smart
entry & start 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 replacing the battery
● Use a battery that conforms to European regulations.
● Use a battery with the same case size as the previous one;
vehicles without cold area specifications or a stop & start system: (LN0),
20 hours rate capacity (20HR) is equiva lent (35Ah) or greater, and perfor-
mance rating (CCA) is equivalent (300A) or greater;
vehicles with cold area specifications: (LN0), 20 hours rate capacity (20HR)
is equivalent (42Ah) or greater, and performance rating (CCA) is equivalent
(390A) or greater; or
vehicles with a stop & start system: (LN2), 20 hours rate capacity (20HR) is
equivalent (60Ah) or greater, and performance rating (CCA) is equivalent
(540A) 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 any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
