the electronic key to the power

ting, the power switch will turn to
ACCESSORY mode.

authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
Stopping the hybrid system
Shift the shift lever to P and press the power switch as you normally do when

As the above procedure is a temporary measure, it is recommended that the elec-
tronic key battery be replaced immediately when the battery is depleted. (P.

When trouble arises

Once the hybrid system has started, remove the jumper cables in the
exact reverse order from which they were connected.
Once the hybrid system starts, have the vehicle inspected at any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped
professional as soon as possible.
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 system while the hybrid system is off.
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 cer-
tain electrical appliances. 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 bat-
tery recharges automatically while the hybrid system is operating.)
When recharging or replacing the 12-volt battery
For vehicles with an alarm: Make sure that the key is not inside the vehicle
when recharging or replacing the 12-volt battery. The key may be locked in the
vehicle if the alarm is activated. (P. 98)
In some cases, it may not be possible to unlock the doors using the smart entry
& start system 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 mal-
function.
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
discharged, be especially careful when reconnecting the 12-volt battery.
