Maintenance and care
GX460_CANADA (OM60F29U)
■Before recharging
When recharging, the battery produces hydrogen gas which is flammable and
explosive. Therefore, observe the following 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 discon-
necting the charger cables to the battery.
■After recharging/reconnecting the battery
●Unlocking the doors using the smart key system may not be possible immedi-
ately after reconnecting the battery. If this happens, use the wireless remote
control or the mechanical key to lock/unlock the doors.
●Start the engine with the “ENGINE START STOP” switch in ACCESSORY
mode. The engine may not start with the “ENGINE START STOP” switch
turned OFF. However, the engine will operate normally from the second
attempt.
●The “ENGINE START STOP” switch mode is recorded by the vehicle. If the bat-
tery is reconnected, the vehicle will return the “ENGINE START STOP” 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 con-
necting the battery if the “ENGINE START STOP” switch mode prior to dis-
charge is unknown.
If the system will not start even after multiple attempts, contact your Lexus dealer.
