■Before recharging
When recharging, the battery produces hydrogen gas which is flammable and
explosive. Therefore, before recharging:
● If recharging with the battery installed on the vehicle, be sure to disconnect
the ground cable.
● Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the battery.
■ After recharging/reconnecting the battery (vehicles with a smart entry &
start system)
The engine may not start. Follow the pr ocedure below to initialize the system.
Depress the brake pedal with the shift lever in N.
Open and close any of the doors.
Restart the engine.
● Unlocking the doors using the smart entry & start system may not be possi-
ble immediately after reconnecting the battery. If this happens, use the wire-
less remote control or the mechanical key to lock/unlock the doors.
● Start the engine with the engine switch in ACCESSORY mode. The engine
may not start with the engine switch turned off. However, the engine will
operate normally from the second attempt.
● The engine switch mode is recorded by the vehicle. If the battery is recon-
nected, the vehicle will return the engine switch mode to the status it was in
before the battery was disconnected. Make sure to turn off the engine
before disconnect the battery. Take extra care when connecting the battery
if the engine switch mode prior to discharge is unknown.
If the engine will not start even after multiple attempts, contact any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.

When trouble arises
AYGO_OM_Europe_OM99R19E
■ 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.
