When connecting the jumper (or

booster) cables, depending on the

situation, the alarm may activate

If you have a set of jumper (or

booster) cables and a second

vehicle with a 12-volt battery,

you can jump start your vehicle

by following the steps below.

1 Vehicles with an alarm

(P.78): Confirm that the

electronic key (vehicles with

a smart key system) or key

(vehicles without a smart key

system) is being carried.

2 Open the hood. (P.302)

minals

When the battery terminals are

removed, the information stored in

the ECU is cleared. Before remov-

ing the battery terminals, contact

your Toyota dealer.

5 Vehicles with a smart key

system: Open and close any

of the doors of your vehicle

with the engine switch OFF.

■Charging the battery

The electricity stored in the battery

will discharge gradually even when

the vehicle is not in use, due to nat-

ural discharge and the draining

effects of certain electrical appli-

ances. If the vehicle is left for a long

time, the battery may discharge,

and the engine may be unable to

start. (The battery recharges auto-

matically during driving.)

6 Maintain the engine speed of

the second vehicle and start

the engine of your vehicle by

turning the engine switch to

ON.

7 Once the vehicle’s engine

has started, remove the

jumper cables in the exact

reverse order from which

they were connected.

■When recharging or replacing

the battery (vehicles with a

smart key system)

●In some cases, it may not be pos-

sible to unlock the doors using the

smart key system when the bat-

tery is discharged. Use the wire-

less remote control or the

mechanical key to lock or unlock

the doors.

Once the engine starts, have the

vehicle inspected at your Toyota

dealer as soon as possible.

■Starting the engine when the

battery is discharged

●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 cannot be started by

push-starting.

■To prevent battery discharge

●The engine switch mode is memo-

rized by the vehicle. When the

battery is reconnected, the system

will return to the mode it was in

before the battery was dis-

charged. 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.

●Turn off the headlights and the

audio system while the engine is

off.

●Turn off any unnecessary electri-

cal 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

20 hour rate capacity (20HR) is

equivalent (45Ah) or greater, and

performance rating (CCA) is

equivalent (286A or 307A) or

greater.

●Do not smoke, use matches,

cigarette lighters or allow open

flame near the battery.

■Battery precautions

• If the sizes differ, the battery can-

not be properly secured.

The battery contains poisonous

and corrosive acidic electrolyte,

while related parts contain lead

and lead compounds. Observe

the following precautions when

handling the battery:

• 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 Toyota

●When working with the battery,

always wear safety glasses and

take care not to allow any bat-

tery fluids (acid) to come into

contact with skin, clothing or the

vehicle body.

dealer.

WARNING

■When removing the battery

terminals

●Do not lean over the battery.

Always remove the negative (-)

terminal first. If the positive (+) ter-

minal contacts any metal in the

surrounding area when the posi-

tive (+) terminal is removed, a

spark may occur, leading to a fire

in addition to electrical shocks

and death or serious injury.

●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.

■Avoiding battery fires or

explosions

●Always wash your hands after

handling the battery support,

terminals, and other bat-

tery-related parts.

Observe the following precautions

to prevent accidentally igniting the

flammable gas that may be emit-

ted from the battery:

●Do not allow children near the

battery.

●Make sure each jumper cable is

connected to the correct termi-

nal and that it is not unintention-

ally in contact with any other

than the intended terminal.

NOTICE

■When handling jumper cables

●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.

When connecting the jumper

cables, ensure that they do not

become entangled in the cooling

fan or engine drive belt.

●Do not allow the + and - clamps

of the jumper cables to come

into contact with each other.
