When trouble arises
If the hybrid system will not start
One of the following may be the cause of the problem:
●The electronic key may not be functioning properly. (
→P. 5 2 8 )
●There may not be sufficient fuel in the vehicle’s tank.
Refuel the vehicle.
●There may be a malfunction in the immobilizer system. ( →P. 76 )
●There may be a malfunction in the steering lock system.
●The hybrid system may be malfunctioning due to an electrical problem such
as electronic key battery depletion or a blown fuse. However, depending on
the type of malfunction, an interim measure is available to start the hybrid sys-
tem. ( →P. 5 2 6 )
One of the following may be the cause of the problem:
●The 12-volt battery may be discharged. ( →P. 5 2 9 )
●The 12-volt battery terminal connec tions may be loose or corroded.
( → P. 4 6 1 )
One of the following may be the cause of the problem:
●The 12-volt battery may be discharged. ( →P. 5 2 9 )
●One or both of the 12-volt battery terminals may be disconnected. ( →P. 4 6 1 )
Contact your Lexus dealer if the problem cannot be repaired, or if repair procedures
are unknown.

When trouble arises
■Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
■To prevent 12-volt battery discharge
●Turn off the headlights and the audio syst em while the hybrid system is stopped.
●Turn off any unnecessary electrical components when the vehicle is running at a low
speed for an extended period, such as in heavy traffic.
■Charging the 12-volt battery
The electricity stored in the 12-volt battery will discharge gradually even when the vehicle
is not in use, due to natural discharge and the draining effects of certain electrical appli-
ances. If the vehicle is left for a long time, the 12-volt battery may discharge, and the
hybrid system may be unable to start. (The 12-volt battery recharges automatically while
the hybrid system is operating.)
■When recharging or replacing the 12-volt battery
●In some cases, it may not be possible to unlock the doors using the smart access system
with push-button start when the 12-volt battery is discharged. Use the wireless remote
control or the mechanical key to lock or unlock the doors.
●The hybrid system may not start on the first attempt after the 12-volt battery has
recharged but will start normally after the second attempt. This is not a malfunction.
●The power switch mode is memorized by the vehicle. When the 12-volt battery is
reconnected, the system will return to the mode it was in before the 12-volt battery was
discharged. Before disconnecting the 12-volt battery, turn the power switch off.
If you are unsure what mode the power switch was in before the 12-volt battery dis-
charged, be especially careful when reconnecting the 12-volt battery.
