nect the ground cable.

■After recharging/reconnecting the 12-volt battery
●Unlocking the doors using the smart ke y system may not be possible immedi-
ately after disconnecting the 12
-volt battery. If this happens, use the wireless
remote control or the mechanical key to lock/unlock the doors.
●Start the hybrid system with the “P OWER” switch in ACCESSORY mode. The
hybrid system may not start with the “POWER” switch turned OFF. However,
the hybrid system will operate normally from the second attempt.
●The “POWER” switch mode is recorded by the vehicle. If the battery is recon -
nected, the vehicle will return the “POWER” switch mode to the status it was in
be
fore the battery was disconnected. Make sure to turn off the power before
disconnect the battery. Take extra care when connecting the battery if the
“POWER” switch mode prior to discharge is unknown.
If the system will not start even after mult i
ple attempts, contact your Lexus dealer.
