■

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.

■

When removing the battery terminals
When the battery terminals are removed, the information stored in the ECU is cleared.

Before removing the battery terminals, contact your Lexus dealer.

■

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 the battery is removed or discharged

●

In some cases, it may not be possible to unlock the doors using the smart access system

with push-button start when the battery is discharged. Use the wireless remote control

or the mechanical 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.

●

The power back door must be initialized. (

P. 138)

■

When replacing the battery

●

Use a battery with the same case size as the previous battery and an equivalent 20

hour rate capacity (20HR) or greater.
• If the sizes differ, the battery cannot be properly secured.

• If the 20 hour rate capacity is low, even if the time period where the vehicle is not

used is a short time, the battery may discharge and the engine may not be able to

start.

●

For details, consult your Lexus dealer.

WARNING

■

When removing the battery terminals
Always remove the negative (-) terminal first. If the positive (+) terminal contacts any

metal in the surrounding area when the positive (+) terminal is removed, a spark may

occur, leading to a fire in addition to electrical shocks and death or serious injury.

■

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 battery.

■

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 vehicle body.

●

Do not lean over the battery.

●

In the event that 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 the battery support, terminals, and other bat-

tery-related parts.

●

Do not allow children near the battery.
