■

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 the battery is removed or discharged

●

Information stored in the ECU is cleared. When the battery is depleted, have
the vehicle inspected at your Toyota dealer.

●

Some systems may require initialization. (

P. 499)

■

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 Toyota 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 cer-
tain 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
key system 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
reconnected, 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 dis-
charged, be especially careful when reconnecting the battery.

■

When replacing the battery

●

Use a battery that conforms to European regulations.

●

Use a battery that the case size is same as the previous one (LN3), 20 hour
rate capacity (20HR) is equivalent (70Ah) or greater, and performance rating
(CCA) is equivalent (603A) 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 vehi-

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

●

For details, consult your Toyota dealer.

WARNING

■

When removing the battery terminals
Always remove the negative (-) terminal first. If the positive (+) terminal con-
tacts 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 flam-
mable 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 “+” termi-
nal 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 pre-
cautions 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 battery-related parts.

●

Do not allow children near the battery.
