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 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 certain elec-
trical appliances. If the vehicle is left for a long time, the 12-volt battery may dis-
charge, 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
●Make sure the key is not inside the vehicl e when recharging or replacing the 12-volt
battery to prevent the doors from being locked with the key left inside the vehicle
when the alarm operates.
●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 wire-
less remote control or the mechanical key to lock or unlock the doors.
●The hybrid system may not start on the fir st 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 bat-
tery was discharged. Before disconnectin g 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.

CAUTION
■Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flammable
gas that may be emi tted from the battery:
●Make sure each jumper cable is connected to the correct terminal and that it is
not unintentionally in contact with any other than the intended terminal.
●Do not allow the other end of the jumper cable connected to the “+” terminal to
come into contact with any other parts or metal surfaces in the area, such as
brackets or unpainted metal.
●Do not allow the + and - clamps of the jumper cables to come into contact with
each other.
●Do not smoke, use matches, cigarette lighters or allow open flame near the bat-
tery.
■12-volt battery precautions
The 12-volt battery contains poisonous and corrosive acidic electrolyte, while
related parts contain lead and lead compounds. Observe the following precau-
tions when handling the 12-volt battery:
●When working with the 12-volt battery, al ways wear safety glasses and take care
not to allow any 12-volt battery fluids (aci d) to come into contact with skin, cloth-
ing or the vehicle body.
●Do not lean over the 12-volt battery.
●In the event that 12-volt battery fluid comes into contact with the skin or eyes,
immediately wash the affected area with water and seek medical attention.
Place a wet sponge or cloth over the affected area until medical attention can be
received.
●Always wash your hands after handling th e 12-volt battery support, terminals, and
other battery-related parts.
●Do not allow children near the 12-volt battery.
■After recharging the 12-volt battery
Have the 12-volt battery inspected at yo ur Lexus dealer as soon as possible.
If the 12-volt battery is deteriorating, continued use may cause the 12-volt battery
to emit a malodorous gas, which may be detrimental to the health of passengers.

8-2. Customization
■Vehicle customization
●When the “Auto Lock by Speed” and “Auto Lock by Shift from P” are both on, the
door lock operates as follows.
• When shifting the shift lever to any position other than P, all the doors will be
locked.
• If the vehicle is started with all the door s locked, the “Auto Lock by Speed” would
not operate.
• If the vehicle is started with any door unlocked, the “Auto Lock by Speed” will operate.
●When the smart access system with push-b utton start is off, the “Select Doors to
Unlock” cannot be customized.
●When the doors remain closed after un locking the doors and the “Auto Relock
Timer” activates, the signals will be generated in accordance with the “Lock/
Unlock Feedback-Tone” and the “Lock/Unlock Feedback-Lights” settings.
■When customizing using the Remote Touch
Stop the vehicle in a safe place, apply the parking brake, and shift the shift lever to P.
Also, to prevent 12-volt battery discharge, leave the engine running
while customizing the features.
CAUTION
■During customization
As the engine needs to be running during customiza-
tion, ensure that the vehicle is parked in a place with adequate ventilation. In a
closed area such as a garage, exhaust gases including harmful carbon monoxide
(CO) may collect and enter the vehicle. This may lead to death or a serious health
hazard.
NOTICE
■During customization
To prevent 12-volt battery discharge, ensure that the engine is run-
ning while customizing features.
