■ Electronic Key Battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping
the electronic key from receiving radio waves.
■ Conditions affecting operation
The smart entry & start system uses weak radio waves. In the following situa-
tions, the communication between the el ectronic key and the vehicle may be
affected, preventing the smart entry & start system, wireless remote control
and engine immobilizer system from operating properly.

Maintenance and care
AYGO_EE_OM99J92E
■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 procedure 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 dealer or repairer, or another duly qualified and equipped professional.

AYGO_EE_OM99J92E
Once the vehicle’s engine has started, remove the jumper cables in
the exact reverse order from which they were connected.
Once the engine starts, have the vehicle inspected at any authorized
Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional as soon as possible.
■ To prevent battery discharge
● Turn off the headlights and the audio system while the engine is off.
● Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic.
■ Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
■ 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.
