WARNING
■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 precautions when han-
dling the 12-volt battery:
●When working with the 12-volt battery, always wear safety glasses and take care not to allow any 12-volt battery fluids (acid) to come into contact with skin, clothing 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, immedi-
ately wash the affected area with water and seek medical attention. Place a wet sponge or cloth over the affected area until medical attention can bereceived.
●Always wash your hands after handling the 12-volt battery support, terminals, andother 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 any authorized Lexus retailer or Lexus autho- rized repairer, or any reliable repairer 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.
■When replacing the 12-volt battery
P. 414
NOTICE
■When handling jumper cables
When connecting the jumper cables, ensure that they do not become entangled in the cooling fans or belt.
■To prevent damaging the vehicle
The exclusive jump starting terminal is to be used when charging the 12-volt battery from another vehicle in an emergency. It cannot be used to jump start another vehicle.

WARNING
■When inspecting under the hood of your vehicle
Observe the following precautions. Failure to do so may result in serious injury such as burns.
●If steam is seen coming from under the h ood, do not open the hood until the steam has subsided. The engine compartment may be very hot.
●After the hybrid system has been turned off, check that the indicator on the power
switch and the “READY” indicator are off. When the hybrid system is operating, the gasoline engine may automatically start, orthe cooling fan may suddenly operate even if the gasoline engine stops. Do not touch
or approach rotating parts such as the fan, which may lead to fingers or clothing (especially a tie, a scarf or a muffler) getting caught, resulting in serious injury.
●Do not loosen the coolant inlet cap or thecoolant reservoir caps while the hybrid sys-tem and radiator are hot.
High temperature steam or coolant could spray out.

■Vehicle customization
●When the speed linked door locking function and shift position linked door locking function 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 speed linked door locking func- tion would not operate.
• If the vehicle is started with any door un locked, the speed linked door locking func- tion will operate.
●When the entry function is off, the select ing doors to unlock cannot be customized.
●When the doors remain closed after unlocking the doors and the automatic door lock function (time elapsed before the automatic door lock function is activated if a door is
not opened after being unlocked) activates, the signals will be generated in accordance with the operation signal (buzzers) and the operation signal (emergency flashers) set-tings.
●Some settings can be changed using a switch or the Remote Touch screen. If a setting ischanged using a switch, the changed setting will not be reflected on the Remote Touchscreen until the power switch is turned off and then to ON mode.
■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 hybrid system operating while customiz-
ing the features.

WARNING
■During customization
As the hybrid system needs to be operating during customization, ensure that the vehi- cle 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.
