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.
