■Stopping the engine
Shift the shift lever to P and press the engine switch as you normally do when stopping the engine.
■Replacing the key battery
As the above procedure is a temporary measur e, it is recommended that the electronic key battery be replaced immediately when the battery is depleted. ( P. 563)
■Alarm (if equipped)
Using the mechanical key to lock the doors will not set the alarm system. If a door is unlocked using the mechanical key when the alarm system is set, the alarm may be triggered.
■Changing engine switch modes
Release the brake pedal and press the engine switch in step above. The engine does not start an d modes will be changed each time the switch is pressed.
( P. 248)
■When the electronic key does not work properly
●Make sure that the smart entry & start system has not been deactivated in the
customization setting. If it is off, turn the function on. (Customizable features P. 685)
●Check if battery-saving mode is set. If it is set, cancel the function. (P. 177)
WARNING
■When using the mechanical key and operating the power windows or moon roof
Operate the power window or moon roof after checking to make sure that there is no possibility of any passenger having any of their body parts caught in the window or moon roof.
Also, do not allow children to operate the me chanical key. It is possible for children and other passengers to get caught in the power window or moon roof.

Connect a positive jumper cable clamp to the positive (+) battery terminal on
your vehicle.
Connect the clamp on the other end of the positive cable to the positive (+)
battery terminal on the second vehicle.
Connect a negative cable clamp to the negative (-) battery terminal on the
second vehicle.
Connect the clamp at the other end of the negative cable to a solid, stationary,
unpainted metallic point away from the battery and any moving parts, as
shown in the illustration.
Start the engine of the second vehicle. Increase the engine speed slightly and
maintain at that level for approximately 5 minutes to recharge the battery of
your vehicle.
Open and close any of the door of your vehicle with the engine switch off.
Maintain the engine speed of the second vehicle and start the engine of your
vehicle by turning the engine switch to IGNITION ON mode.
Once the vehicle’s engine has started, remove the jumper cables in the exact
reverse order from which they were connected.
Once the engine starts, have the vehicle inspected at any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional as soon
as possible.
■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 stopped. (Vehicles with a Stop & Start system: except when the engine is stopped by the Stop &
Start system.)
●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 beunable to start. (The battery recharges automatically during driving.)

When trouble arises

■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. Us e the wireless remote control or the mechan-
ical key to lock or unlock the doors.
●The engine may not start on the first attempt after the battery has recharged but will start normally after the second attempt. This is not a malfunction.
●The engine switch mode is memorized by the vehicle. When the battery is recon-nected, the system will return to the mode it was in before the battery was discharged. Before disconnecting the battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery discharged, be especially careful when reconnecting the battery.
●Vehicles with Stop & Start system:
For a while after the battery terminals have been disconnected and reconnected, for a while after the battery has been replaced, the Stop & Start system may not automati-cally stop the engine for approximately 5 to 60 minutes.
■When exchanging the battery (vehicles with Stop & Start system)
Use a battery specified for use with the Stop & Start system and equivalent to a genuine battery. If an unsupported battery is used, Stop & Start system functions may be
restricted to protect the battery.
Also, battery performance may decrease and the engine may not be able to restart. Contact any authorized Lexus retailers or Le xus authorized repairers, or any reliable
repairers.

WARNING
■Avoiding battery fires or explosions
Observe the following precautions to preven t 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 notunintentionally 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 battery.
●If the battery fluid level is excessively low ( P. 530), do not use the battery.
■Battery precautions
The battery contains poisonous and corrosive acidic electrolyte, while related parts contain lead and lead compounds. Observ e 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 vehicle body.
●Do not lean over the battery.
●In the event that battery fluid comes into contact with the skin or eyes, immediatelywash 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 bat-

6969-2. Customization
RC200t_RC F_EE(OM24728E)
■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, both side the doors will be
locked. • If the vehicle is started with both side doors locked, the speed-detecting automaticdoor 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 custom-ized.
●When the doors remain closed after unlocking the doors and the timer activated auto-
matic door lock function activates, signals will be generated in accordance with the operational signal (Emergency flashers) function setting.
●Some settings can be changed using a switch or the audio system screen. If a setting is
changed using a switch, the changed setting will not be reflected on the audio system screen until the engine switch is turn ed off and then to IGNITION ON mode.
■When customizing using the Remote Touch or Lexus Display Audio controller
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.
WARNING
■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 monoxide (CO) may collect and enter the vehicle. Thismay lead to death or a serious health hazard.
NOTICE
■During customization
To prevent battery discharge, ensure that the engine is running while customizing fea-
tures.
