After recharging/reconnecting the bat-

tery

The engine may not start. Follow the proce-

dure below to initialize the system.

1

Shift the shift lever to P.

2

Open and close any of the doors.

3

Restart the engine.

●

Unlocking the doors using the smart 

access system with push-button start may 

not be possible immediately after recon-

necting the battery. If this happens, use 

the wireless remote control or the 

mechanical key to lock/unlock the doors.

●

Start the engine with the engine switch in 

ACCESSORY mode. The engine may 

not start with the engine switch turned off. 

However, the engine will operate nor-

mally from the second attempt.

●

The engine switch mode is recorded by 

the vehicle. If the battery is disconnected 

and reconnected, the vehicle will return 

the engine switch mode to the status it 

was in before the battery was discon-

nected. Make sure to turn off the engine 

before disconnecting the battery. Take 

extra care when connecting the battery if 

the engine switch mode prior to the bat-

tery being disconnected is unknown.

If the system will not start even after multiple 

attempts, contact your Lexus dealer.

WARNING

Chemicals in the battery

Batteries contain poisonous and corro-

sive sulfuric acid and may produce 

hydrogen gas which is flammable and 

explosive. To reduce the risk of death or 

serious injury, take the following precau-

tions while working on or near the bat-

tery:

●

Do not cause sparks by touching the 

battery terminals with tools.

●

Do not smoke or light a match near the 

battery.

●

Avoid contact with eyes, skin and 

clothes.

garage or closed room where there is 

insufficient ventilation.

■

How to recharge the battery

at a quicker rate.

Emergency measures regarding 

electrolyte

●

If electrolyte gets in your eyes

Flush your eyes with clean water for at 

least 15 minutes and get immediate 

medical attention. If possible, continue 

to apply water with a sponge or cloth 

while traveling to the nearest medical 

facility.

Wash the affected area thoroughly. If 

you feel pain or burning, get medical 

attention immediately.

If electrolyte gets on your clothes

It can soak through clothing on to your 

skin. Immediately take off the clothing 

and follow the procedure above if nec-

essary.

Drink a large quantity of water or milk. 

Get emergency medical attention 

immediately.
