8-2. Steps to take in an emergency

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

Toyota retailer or Toyota authorized repairer, or any reliable repairer

as soon as possible.

■ Starting the engine when the battery is discharged (vehicles with auto-

matic transmission)

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.

(Vehicles with Stop & Start system: Except when the engine is stopped due

to 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.

■ When the battery is removed or discharged

●Information stored in the ECU is cleared. When the battery is depleted, have

the vehicle inspected at any authorized Toyota retailer or Toyota authorized

repairer, or any reliable repairer.

●The power windows may not close normally. In this case, initialize the power

windows. (if equipped) (P. 185)

●If it is necessary to initialize the panoramic view monitor (if equipped), refer

“Navigation and multimedia system Owner’s manual” or “Multimedia

Owner’s Manual”.

■ 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.)

8-2. Steps to take in an emergency

605

■ When recharging or replacing the battery (vehicles with smart entry &

start system)

●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.

● 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.

● Vehicles with Stop & Start system: After the battery terminals have been dis-

connected and reconnected or, the battery has been replaced, the Stop &

Start system may not automatically stop the engine for up to an hour.

■ When replacing the battery

● Use a battery that conforms to European regulations.

● Use a battery with the same case size as the previous battery and an equiv-

alent 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 vehi-

cle is not used is a short time, the battery may discharge and the engine

may not be able to start.

● Vehicles with Stop & Start system: Use a genuine battery specifically

designed for use with the Stop & Start system or a battery with equivalent

specifications 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 Toyota retailer or Toyota authorized

repairer, or any reliable repairer for details.

● For details, consult any authorized Toyota retailer or Toyota authorized

repairer, or any reliable repairer.

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.
