When trouble arises
LS460/LS460L_GE (OM50G06E)
■Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
■To prevent battery discharge
●Turn off the headlights and the audio system while the engine 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 battery
The electricity stored in the battery will discharge gradually even when the vehicle is
not in use, due to natural discharge and the draining effects of certain electrical
appliances. If the vehicle is left for a long time, the battery may discharge, and the
engine may be unable to start. (The battery recharges automatically during driving.)
■When recharging or replacing the battery
In some cases, it may not be possible to unlock the doors using the smart entry &
start system when the battery is discharged. Use the wireless remote control or the
mechanical key to lock or unlock the doors.
■If the battery is discharged
The information stored in the computer will be deleted.
If the battery is discharged, have the vehicle inspected by your Lexus dealer.

CAUTION
■Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flammable
gas that may be emitted 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.
■Battery precautions
The battery contains poisonous and corrosive acidic electrolyte, while related
parts contain lead and lead compounds. Observe the following precautions when
handling the battery:
●When working with the battery, always wear safety glasses and take care not to
allow any battery fluids (acid) to come into contact with skin, clothing or the vehi-
cle body.
●Do not lean over the battery.
●In the event that 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 be
received.
●Always wash your hands after handling the battery support, terminals, and other
battery-related parts.
●Do not allow children near the battery.
NOTICE
■When handling jumper cables
When connecting the jumper cables, ensure that they do not become entangled in
the cooling fans or engine drive belt.

Vehicle specifications
LS460/LS460L_GE (OM50G06E)
■Vehicle customization
●When the speed-detecting automatic door lock and shift-linked automatic door
lock 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 doors locked, the speed- detecting automatic
door lock will not operate.
• If the vehicle is started with any door unlocked, the speed- detecting automatic
door lock will operate.
●When the smart entry & start system is off, the entry unlock function cannot be cus-
tomized.
●When the doors remain closed after unlocking the doors and the timer activated
automatic door lock function activates, signals will be generated in accordance
with the operation buzzer volume and operational signal (Emergency flashers)
function 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 battery discharge, leave the engine running while customizing the
features.
CAUTION
■During customization
As the engine needs to be running during customization, 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 mo noxide (CO) may collect and enter the
vehicle. This may lead to death or a serious health hazard.
NOTICE
■During customization
To prevent battery discharge, ensure that the engine is running while customizing
features.
