Before recharging
■
When recharging, the battery produces
hydrogen gas which is flammable and
explosive. Therefore, observe the following
precautions 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 char-
●
ger is off when connecting and discon-
necting the charger cables to the battery.

tery
●
Unlocking the doors using the smart
access system with push-button start may
not be possible immediately after recon-
necting 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 switch in
ACC. 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 disconnected
and reconnected, the vehicle will return
the engine switch mode to the status it
was in before the battery was discon-
nected. Make sure to turn off the engine
switch before disconnecting the battery.
Take extra care when connecting the bat-
tery if the engine switch mode prior to the
battery being disconnected is unknown.
If the system will not start even after multiple
attempts at all the methods above, contact
your Lexus dealer.
