■
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.)
■
When recharging or replacing the battery (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, equivalent or greater 20 hour rate
capacity (20HR), and equivalent or greater performance rating (CCA) as the
battery which is being replaced.
Type A
Type B
Type C
The case size, 20 hour rate capacity (20HR) and performance rating
(CCA) are specified on the label attached to the battery.
• 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.
